Textile treatment

A textile treatment composition which comprises; a textile binding agent which forms a chemical bond with the outer layer of the textile according to the formula (Ia): ##STR1## and, a barrier agent which forms a chemical bond with the textile binding agent and which increases the surface tension of the textile. Methods for treating textiles with the treatment composition, and kits comprising the components are also provided.

BACKGROUND OF THE INVENTION 
The present invention relates to a textile treatment composition, methods 
of treating textiles and to textiles which have been treated. Compositions 
and methods of the present invention are especially suitable to impart 
stain resist properties to textiles such as wool, cotton and nylon, but 
the invention is not limited thereto. 
Various processes exist for the treatment of textiles to impart some stain 
resist qualities thereto. These processes have limited effectiveness with 
some textiles such as wool. For example, fluorocarbons are used to provide 
oil and water repellancy to textiles such as fabrics, furnishings, carpets 
and clothing. The fluorocarbon prevents wetting of the textile thus 
minimizing contact between the textile and the foreign substance. However 
such treatment does not impart stain resist properties to the textile and 
such an approach offers little protection to the textile where the foreign 
substance is a substance such as F D & C Red 40, an acid dye commonly 
added to food and beverages. Such treatment is also non-durable and wears 
off quickly. Some processes exist that are suitable to treat nylon, for 
example nylon carpets, however it has been found that these treatments are 
unsuitable to treat wool, for example wool carpets. 
It is known that wool fibre material can be treated with sulphonated 
compounds so as to protect the material against soiling by oily foods or 
aqueous beverages which have been dyed with synthetic dyes such as F D & C 
Red 40. See for example U.S. Pat. No. 4,699,812 and 4,857,392. However, 
the stain resisting effect is inadequate. 
It is also widely known that the lack of durability of stain resist 
finishes of nylon carpets is such that it does not allow the use in 
commercial installations. 
European Patent Application 267681 discloses a method for providing fibrous 
polyamide materials with stain resistance comprising contacting the 
fibrous polyamide materials with aqueous solution comprising a normally 
solid, water-soluble, partially sulphonated resin, which comprises the 
condensation product of at least one phenolic compound and an aldehyde, 
and a water-soluble divalent metal salt. 
U.S. Pat. No. 4,592,940 discloses a process for imparting stain resistance 
to a carpet having a pile made of nylon yarn comprising immersing the 
carpet in an aqueous solution of a selected phenol-formaldehyde 
condensation product. 
U.S. Pat. No. 4,501,591 discloses an improvement in certain processes for 
continuously dyeing polyamide carpets whereby stain resistance is imparted 
to the carpets during the dyeing process. The improvement comprises adding 
an alkali metal silicate and a sulphonated phenol-formaldehyde 
condensation product to the dye liquor used in the dyeing process. 
European Patent Application 235 989 discloses an improvement in a process 
for applying sulphonated naphthol- or sulphonated phenol-formaldehyde 
condensation products to polyamide textile articles to render them stain 
resistant, the improvement comprising applying the condensation products 
at a pH of between 1.5 and 2.5. 
U.S. Pat. No. 4,940,757 discloses a stain resistant composition which is 
prepared by polymerizing an .alpha.-substituted acrylic acid in the 
presence of a sulphonated aromatic formaldehyde condensation polymer.

In a preferred aspect of the present invention the fibre treatment 
composition may further include a solvent for the textile binding agent 
and/or barrier agent. Accordingly, in a further aspect of the present 
invention there is provided a textile treatment composition including: 
a textile binding agent which forms a chemical bond with the outer layer of 
the textile; 
a barrier agent which forms a chemical bond with said binding agent and 
which increases the surface tension of the textile; and 
a solvent. 
Any suitable solvent may be used. Suitable solvents include aqueous and 
organic solvents. In a preferred embodiment of the invention an aqueous 
solvent is used. Preferably the solvent is water of similar quality to 
that normally used in textile dyeing. In a preferred embodiment, the 
solvent used is a common solvent to that used in any other processes which 
may be used to treat the textile, such as dyeing. In one form the 
composition and for example a dye which may be used to treat the textile 
may both be placed in the same solution. 
In a further preferred embodiment the composition of the present invention 
further includes a salt. The salt may include an alkali metal salt, for 
example sodium chloride (common salt). 
It has surprisingly been found that the treatment with common salt during 
or subsequent to treatment with the composition in accordance with the 
method of the present invention increases the stain resistance imparted to 
the textile. 
Accordingly in a further aspect of the present invention there is provided 
a textile treatment composition including an effective amount of: 
a textile binding agent which forms a chemical bond with the outer layer of 
the textile; 
a barrier agent which forms a chemical bond with said binding agent and

have a pH less than 8. Preferably the composition is buffered such that it 
has a pH in solution of between 3.0 and 6.0. 
The present invention also provides a method of treatment of a textile to 
render it stain resistant comprising: 
providing a textile; and 
contacting the textile with a textile treatment composition including 
a textile binding agent which forms a chemical bond with the outer layer of 
the textile; 
a barrier agent which forms a chemical bond with said binding agent and 
which lowers the surface tension of the textile; 
for a time sufficient and at a temperature sufficient to permit reaction 
therebetween. 
This method is particularly useful in treating wool of all types including 
but not limited to knitting wool and wool carpet; and other textiles such 
as nylon and cotton. 
Preferably the composition used in the method includes a ratio of textile 
binding agent to barrier agent of from 1:2 to 10:1. The preferred ratio 
will depend on the textile binding agent and barrier agent used and also 
the textile to be treated. The ratio may be established by the person 
skilled in the art. When the composition is to be applied to wool or 
wool/nylon blends for example it has been found that when the compound or 
compounds sold under the trade designation "Paranyl B" is used as the 
textile binding agent, a ratio of 2:1 is suitable. It has been found when 
the compound or compounds sold under the trade designation "Sandospace R" 
is used as the textile binding agent that a ratio of between 6:1 and 7:1 
is suitable, and 6.66:1 is especially suitable. 
The term "wool/nylon blends" includes for example 80% wool to 20% polyamide 
and 70% wool to 30% polyamide which are commonly used in the carpet trade. 
When the composition is to be applied to nylon it has been found that when 
the compound or compounds sold under the trade designation "Paranyl B" is 
used as the textile binding agent that a ratio of 0.8:1 is suitable. It 
has been found that when the compound or compounds sold under the trade 
designation "Sandospace R" is used as the textile binding agent that a 
ratio of between 2:1 and 3:1 is suitable and 2.66:1 is especially 
suitable. 
The composition is preferably applied to the textile in an amount of 
between about 2 to about 35%, preferably about 5 to about 10% of 
composition to weight of textile to be treated. By way of example of the 
method 10 kilograms of a wool or wool/nylon blend carpet may 
advantageously be treated using a solution containing 0.75 kilograms of 
the compound or compounds sold under the trade designation "Paranyl B" 
agent and 0.375 kilograms of barrier agent, or 2.5 kilograms of the 
compound or compounds sold under the trade designation "Sandospace R" and 
0.375 kilograms of binding agent. 
The treatment solution which is used to treat the textile in accordance 
with the above method is heated. In the case of wool, the treatment 
solution is preferably heated to and maintained at a temperature within a 
range of about 85.degree. C. to about 105.degree. C. More preferably the 
treatment solution is heated to and maintained at a temperature of about 
100.degree. C. It will be appreciated that for textiles other than wool 
different temperatures may be used. It will also be appreciated that the 
temperature should not be so high as to damage the wool or other textile. 
In accordance with the method of the present invention, the textile to be 
treated is placed in the treatment solution including the composition, for 
a time sufficient to allow the composition to act upon the textile. It 
will be appreciated that time will be dependent upon the nature of the 
textile and will also be temperature and pressure dependent. The treatment 
time may be established by a person skilled in the art according to the 
type of textile to be treated and the temperature and pressure used. By 
way of example, wool placed in the above referred to most preferred 
solution at 100.degree. C. will require about 3 to 6 minutes. In one 
embodiment of the method, the treatment solution is provided by mixing the 
composition including binding agent and barrier agent as described above, 
together with an already existing solution used in the manufacturing 
process. Preferably the existing treatment solution meets the above 
preferred temperature, pH, solvent, pressure and other relevant 
requirements. By way of example, the treatment solution may be provided by 
placing the composition including textile binding agent and barrier agent 
together with the dye solution used to dye the textile. The textile may 
then be treated with the composition of the present invention and dyed at 
the same time. For example if level dyeing acid dyes are used for dyeing 
the textile, the textile treatment according to the present invention can 
be done during the dyeing either from an exhaust bath or in a continuous 
dyeing process. The composition of the present invention may be simply 
added to the dye liquor and the dyeing may be carried out as normal. 
For other classes of dye commonly used on wool, for example premetallised 
and reactive dyes, the stain resist finish is preferably applied as a 
dyebath post treatment to avoid partial blocking of the dyes. For example, 
the composition of the present invention may be added to the boiling 
dyebath at the end of the dyeing process and the dyebath may be kept 
boiling for a sufficient time to effect the treatment of the textile 
according to the present invention. For example the dyebath may be kept 
boiling for approximately a further 30 minutes. 
It will be appreciated that the method of the present invention could be 
carried out in a "closed" or at least "partially closed" system in which 
the solution including the composition is applied to the textile under 
pressure. It will be appreciated that the pressure should not be 
sufficient that damage would be caused to the textile. It will be further 
appreciated that the temperature and composition reaction time will vary 
in relationship with the pressure used. 
The textile treated in the manufacturing process is preferably treated with 
a common salt application liquor during or subsequent to dyeing. The 
treatment with the common salt application liquor may take place 
concurrent with or subsequent to treatment with the composition in 
accordance with the method of the present invention. Most preferably the 
common salt application liquor is applied at the same time as the 
treatment composition. The concentration of common salt may be about 4 to 
30% to the weight of the textile to be treated, preferably 4 to 10% and 
most preferably 4 to 5%. 
In a further method according to the present invention the textile may be 
treated either by applying the textile binding agent or barrier agent to 
the textile at a time different to the time at which the other agent is 
applied to the textile. In one preferred form the textile will be treated 
in a solution including textile binding agent and at a later stage in the 
treatment process a solution including barrier agent is used to treat the 
textile; or vice versa. For example, the textile is treated with a 
solution including textile binding agent concurrent with dyeing of the 
textile and barrier agent is included subsequent to the dyeing process. 
The textile is preferably treated with a common salt application liquor 
concurrent with or subsequent to treatment with the barrier agent. 
It has been found that the following are exemplary conditions in which the 
method of the present application may be performed; 
(a) in the case of wool and wool/nylon blends using a continuous dyeing 
method, the textile treatment method of the present invention is performed 
concurrently with the dyeing process. An aqueous solution consisting of 
acid levelling dye stuffs, textile binding agent, preferably 7.5% "Paranyl 
B" or 25% "Sandospace R" barrier agent, preferably 3.75%, and common salt, 
preferably 5%, is buffered to a pH of between 3.0 and 6.0 depending on the 
required dyeing conditions. The solution is applied to the wool or 
wool/nylon blend by any commonly used technique such as padding, flooding, 
spraying or printing. The application rates mentioned above are based on 
the weight of textile treated. The textile is then steamed at between 
95.degree. C. and 100.degree. C. for a sufficient time to fix the dye 
stuff and the textile treatment composition, usually about 3 to 6 minutes. 
The textile is then rinsed and dried. 
(b) In the case of application to wool and wool/nylon blends a batch wise 
exhaustion of the dye stuff and textile treatment composition may also be 
conducted concurrently. The textile binding agent, preferably 7.5% 
"Paranyl B" or 25% "Sandospace R" , barrier agent, preferably 3.75%, and 
common salt, preferably 5%, based on the weight of the textile to be 
treated is added to a bath at the beginning of the dyeing process together 
with acid levelling dye stuffs and a suitable acid to give a pH of between 
3.0 and 6.0. The dyeing process is carried out as normal. 
(c) The above continuous dyeing and batch wise exhaustion processes may 
similarly be carried out on polyamide textiles except that the suitable 
percentages of the textile binding agent is 1.2% of "Paranyl B" or 4% of 
"Sandospace R" based on the weight of the textile and 1.5% barrier agent 
based on the weight of the textile, and common salt 4 to 5% based on the 
weight of the textile. 
Whilst we do not wish to be restricted by theory, it is postulated that the 
achievement of stain-resistant properties imparted to the textile can be 
accounted for in the following way. Treatment of the textile with the 
textile binding agent will result in attach of groups on the textile such 
as amino groups on wool (for example on lysine residues) with the triazine 
ring, resulting in displacement of one of the chlorines as chloride ion. 
For example: 
##STR15## 
For steric reasons, it is believed that it is unlikely that the second 
chlorine could also be displaced by another wool amino group. 
The second chlorine, it is postulated, is displaced by another nucleophile, 
such as the phenolic constituents of the barrier agent. For example: 
##STR16## 
In the above example, since the textile binding agent is covalently and 
irreversably bound to the textile and the barrier agent is covalently and 
irreversably bound to the binding agent, the textile is effectively coated 
with an organic structure containing numerous highly polar acidic groups 
(i.e. SO.sub.3 H and 
##STR17## 
Such groups would present electrostatic repulsion to incoming staining 
molecules and not allow them to bind strongly. In the case of wool, the 
usual wool protein structures would be effectively protected by a veneer 
of polymer-like structures. The original dye molecules applied prior to or 
together with the composition of the present invention would remain fast 
and not be destabilised as they would be embedded in the above coating. 
It has also been found that treatment of textiles by the composition of the 
present invention results in textiles having a good twist retention and 
improved wearability. It is postulated that the internal charge repulsion 
of the polar acidic groups attached to the modified textile provide a 
steric stiffening of the fibre, which results in the good twist retention 
and improved wearability. 
The present invention also provides a textile having improved stain-resist 
properties, and/or improved twist retention and/or improved wearability. 
The textile according to the present invention comprises a textile which 
has been treated with the composition of the present invention. Preferably 
the textile of the invention has been treated according to the method of 
the present invention as described above. 
It has also surprisingly been found that the durability of the stain resist 
treatment of the present invention is superior to known stain resist 
finishes on nylon carpets. 
The present invention also provides a textile treatment kit comprising: 
a first component textile binding agent which forms a chemical bond with 
the outer layer of the textile, in a suitable container; and 
a second component barrier agent which forms a chemical bond with said 
binding agent and which increases the surface tension of the textile, in a 
suitable container.

The present invention will now be more fully described with reference to 
the accompanying examples. It should be understood, however, that the 
description following is illustrative only and should not be taken in any 
way as a restriction on the generality of the invention described above. 
EXAMPLE 1 
In the following example a sample of wool carpet was treated with a 
composition comprising "Cibatex RN" and "Paranyl B". The following table 
illustrates the stain resist properties of untreated carpet compared to 
treated carpet.

As can be seen above, the treated carpet showed a very good stain block 
effect on a wood carpet when tested with F D & C Red 40. To the best of 
the Applicants knowledge, there is no compound on the market which has the 
same effect. 
EXAMPLE 2 
In the following example the 3M carpet stain release test 1 was used. This 
test is designed to provide a simple standard method for measuring and 
rating the effectiveness of removing stains from carpet. 
The following is the 3M carpet stain release test 1 procedure and 
evaluation: 
Test Procedure 
1. Test pH of staining test solution. It must be between 2.5-4.0. Record pH 
value. Water temperature should be 21.degree..+-.3.degree. C. 
2. Draw 15 ml of staining test solution into the applicator syringe, avoid 
bubbles. 
3. Place the applicator in the center of the carpet face. 
4. Twist the applicator from left to right so it touches the carpet 
backing. With heavy face weights this is not always possible, strive for 
deepest penetration achievable. 
5. Slowly depress plunger of the syringe to stain the carpet with the 
staining test solution in the syringe. Wait a few seconds to insure all 
staining test solution has transferred into the carpet. 
6. Place hands evenly on base of the applicator, twist from left to right. 
7. Remove applicator and allow stained carpet to sit undisturbed for 8 
hours on a hard, nonabsorbent surface. 
8. Rinse the carpet well under flowing tap water 21.degree..+-.3.degree. C. 
for a minimum of 3 minutes. 
9. Remove excess water by squeezing or an extraction method. 
10. Allow rinsed sample to air dry completely. 
Evaluation 
1. Place the 3M Stain Release Rating Scale 1-8 against the back wall of a 
Lighting chamber. 
2. Place test sample in front of the Rating Scale. On cut pile carpet brush 
the pile with your hand in the direction giving the greatest lay to the 
yarn. 
3. Visually rate stained area by comparing to the rating scale. Each test 
sample will be rated two times. The first time with the pile lay facing 
the rating scale. The second time, rotated 90.degree.from the first rating 
position. Record each rating to the nearest 1/2 point. 
4. Average the 2 ratings for each test sample. If the final value is 
between half point increments, round to the next higher half point 
increment (example: 1st value=3.5, 2nd value=4.0, average=3.75; Record the 
value as 4.0). 
A sample of carpet was treated with "Paranyl B" at 100.degree. C. for 30 
minutes with 5% common salt. Table 2 illustrates the various amounts of 
"Paranyl B" which were applied and whether the sample passed or failed the 
above test.

A further test was conducted using "Cibatex RN". A sample of carpet was 
treated with "Cibatex RN" at 100.degree. C. for 30 minutes with 5% common 
salt. Table 3 illustrates the amount of "Cibatex RN" which was used and 
whether the carpet passed or failed the test.

A sample of carpet was then treated with a composition comprising a mixture 
of 7.5% "Paranyl B" with 3.75% "Cibatex RN" and 5% common salt. The carpet 
was treated at 100.degree. C. for 30 minutes. The sample of carpet treated 
with this composition according to the present invention had no trouble 
passing the 3M carpet stain release test. 
EXAMPLE 4 
The 3M carpet stain release test 1 was also carried on a nylon carpet which 
had been treated with a composition comprising 1.8% "Paranyl B", 1.0% 
"Thiotan WPN" liquid, and 4% common salt. The carpet passed the 3M carpet 
stain release test 1. 
EXAMPLE 5 
A sample of carpet which had been treated by composition comprising 
"Cibatex RN" and "Paranyl B" was compared with an untreated sample of 
carpet using 4 commonly used tests in the industry. The carpet used was a 
100% wool carpet. Each method was rated against Grey Scales for staining 
by three judges to give the required ratings. 
The staining was rated against a new carpet sample, any change in colour 
tone of carpet was neglected and only the stained area was considered.

A rating of 4 is considered to be very good, only very slight colouration 
on the tips of yarn. 
As can be seen above, the stain has effectively been removed in the treated 
sample under all of the above tests. 
EXAMPLE 6 
Two polyamide carpets namely a 32 ounce per square yard plush pile obtained 
from DuPont and T66 Superba Heat Set Continuous Filament yarn were treated 
by two different methods: 
(a) DuPont "Stain Release" method 
(b) Textile treatment method according to the present invention. 
In every other respect, the two carpet samples were finished and treated 
similarly. 
Samples of each carpet were then subjected to rapid wear tests on a hexapod 
wear tester through 6000 and 9000 cycles. Both worn and unworn samples 
were then subjected to the 3M 8 hour stain test and the DuPont 24 hour 
stain test. The results are shown in Table 5.

EXAMPLE 7 
The example illustrates the improved twist retention and wearability of a 
carpet sample which has been treated with the textile treated treatment 
composition of the present invention. 
A 100% wool cut pile carpet weighing 50 ounces per square yard was tufted 
on a 1/10 Guage Tufting machine. Half of this carpet was dyed using acid 
levelling dyes on an industry standard continuous dyeing line. The other 
half of the carpet was dyed under the same conditions but incorporating 
the textile treatment composition of the present invention in with the 
dyeing liquor. The two samples of carpet were then subjected to 8600 
cycles of a hexapod wear testing machine and each sample was then rated 
for appearance retention using a grey scale rating system from 1 to 5 in 
which 5 indicates no change in appearance. The results are 15 provided in

EXAMPLE 9 
A sample of 10 g of a woollen carpet yarn is treated in the dye apparatus 
with a liquor in the liquor ratio of 1:30 which contains 7.5%* of the 
sodium salt of 4-[(4,6-dichloro -1,3,5-triazin-2-yl)amino] benzene 
sulphonic acid (a) 10% NaCl. 
The pH of the liquor is adjusted to 5.5 with acetic acid. 
(* all percentage figures are based on the weight of material) 
The liquor is heated to 98.degree. C., the previously moistened sample is 
immersed in the liquor and treatment is carried out for 30 minutes at this 
temperature. After this 3.75% of the ammonium salt of a condensation 
product of naphthalene sulphonic acid, dihydroxy-diphenylsulphone and 
formaldehyde (b) is added to the treatment bath, and treatment is 
continued for 30 minutes at 98.degree. C. Subsequently the material is 
rinsed and dried. 
EXAMPLE 10 
The procedure is the same as in Example 9, however, instead of the benzene 
sulphonic acid derivative specified there, 7.5% 
2-[(4,6-dichloro-1,3,5-triazin-2-yl)amino]naphthalene-1,5-disulphonic acid 
(c) is used. 
EXAMPLE 11 
The procedure is the same as in Example 9, however, instead of the 
condensation product specified there, 3.75% of a condensation product of 
phenol sulphonic acid and dihydroxydiphenylsulphone with 0.4 mole of 
formaldehyde (d) is used. 
EXAMPLE 12 
The procedure is the same as in Example 9, however, instead of the woollen 
carpet yarn a sample of 10 g of a woollen carpet of 350 g/m.sup.2 is used 
and instead of the benzene sulphonic acid derivative, 7.5% of the 
naphthalene-1,5disulphonic acid derivative of Example 10 is used, and 
instead of the condensation product of Example 9, the condensation product 
of Example 11 is used. 
EXAMPLE 13 
The procedure is the same as in Example 12, however, instead of the 
naphthalene-1,5-disulphonic acid derivative, 7% of the derivative 
according to example 9 is used and instead of the condensation product of 
Example 11, 3.5% of the condensation product of phenol sulphonic acid and 
dihydroxydiphenylsulphone with 0.58 moles formaldehyde (e) is used. 
EXAMPLE 14 
The procedure is the same as in Example 9, however, instead of the benzene 
sulphonic acid derivative, 7.0% of the naphthalene-1,5-disulphonic acid 
derivative of Example 10 is used, and instead of the condensation product 
of Example 9 3.5% of the condensation product according to Example 13 is 
used. 
Comparative Examples A-F 
Six samples of woollen carpet yarn of 10 g each are treated with liquor in 
the liquor ratio of 1:30 which contain 
10% NaCl and each 
7.5% of the component (a) or (b) or 3.75% of the component (c), (d) or (e), 
respectively not a single component. 
The pH value of the liquors is adjusted to 5.5 with acetic acid. 
The moistened samples are then immersed in the liquors which have been 
heated to 98.degree. C. and treatment is carried out for 60 minutes at 
this temperature. Subsequently, the samples are rinsed cold and dried. 
The samples which were dressed according to the Examples 9 to 14 and the 
comparative Examples A to F are each separately immersed at a liquor ratio 
of 1:20 in a liquor at 20.degree. C. which contains 80mg/L of the acid dye 
FD & C Red 40 and 0.5 g/L of citric acid (pH 3) and are kept there for 15 
minutes at this temperature. After this they are rinsed cold for 5 minutes 
and are dried at 60.degree. C.
