 The labelling and marking of textiles and household textile 
articles  
1 Scope   
This Draft Uganda S tandard makes recommendations for direct mark ing on textile piece -goods of information 
that facilitates their correct invoicing and use subsequent to their manufacture.  It also specifies alternative 
methods for designating the fibre content of textiles and textile  products and for applying this infor mation to 
made -up products, piece -goods and yarns. It also  specifies the methods to be used for determining the fibre 
content of textiles and textile products.  
It includes recommendations for the labelling of each piece of textile fabric and for the markin g of bulk 
containers in order to facilitate identification, inspection, invoicing, stock control, and any  further process 
control during the subsequent manufacture of textile articles, for example control during the cut, make and trim 
of apparel.

4 Direct markings on woven and knitted piece -goods  
4.1 Truth marks  
After measuring the gross length or the gros s mass of the piece (as relevant), the manufacturer  should place, 
on each end of each piece and of each cut within a piece, a suitable indelible marking  that will enable 
unauthorized cutting of the fabric during subsequent handling to be detected.  
4.2 Indication of face side  
The side of the fabric that the manufacturer intends to be taken as the face side should be indicated  by the 
manufacturer by placing an appropriate indelible marking, on this side of the fabric, at at least  one end of each 
piece and of each cut within a piece. The wording used should be “FACE SIDE”.  
NOTE  This marking could also be used for the truth marks.  
5 Labelling of piece -goods and marking of bulk containers  
5.1 Piece labels  
5.1.1  Attachment of piece labels  
After the final inspectio n of each piece of fabric, the manufacturer should securely attach a label to  one end of 
the piece, either by means of a string or by stapling it onto a narrow strip of the fabric  made by tearing the end 
of the fabric about three -quarters along the width o f the piece.  
If the fabric is to be wrapped, the string attaching the label to the piece should be long enough to  permit the 
label to be read from outside the wrapping.  
If the fabric is to be rolled, the label should be attached to the inner end of the rol l. DUS 426: 2018

7.5.1 In etch -printed and embroidered fabrics, the individual fibre type content shall be separately  indicated 
by the marking of the name of the base fabric and of the etched parts or of the embroidery  yarns by the listing, 
in de scending order of dominance, by mass, of the generic name of each fibre  type with or without a n 
indication of the percentages  
7.5.2 In fabrics where the embroidered parts do not exceed 10 % of the surface area of the fabric,  the fibre 
content of the embroi dery yarns need not be indicated  
7.6 Marking of velvet and plush fabrics  
If the backing of any velvet or plush fabric is distinct from, and does not have the same fibre content  as, the 
use-surface, the fibre content shall be indicated by the name of each c omponent being  marked by the listing, 
in descending order of dominance, by mass, of the generic name of each  fibre type with or without a n 
indication of the percentages  DUS 426: 2018

 7.7 Marking of textile floor coverings  
If the backing of textile floor coverings is different from that of the use -surface , the fibre of the use -need be 
indicated  
7.8 Marking of core -spun yarns on packages  
If a yarn has a core and cover of different fibre content, the fibre content  shall be marked  separately, for 
example "polyester core", " cotton outer" or "cotton -covered polyester".  
7.9 Main linings  
7.9.1 Class  
Any lining, such as the linings of curtains, jackets, upholstery, skirts and coats, can be classed as a  main 
lining.  
7.9.2 Marking  
7.9.2.1  The marking on a textile product shall indi cate the fibre content of any main lining and shall  state 
which fibre type applies to which part, for example "all cotton; lining: acrylic".  
7.9.2.2  The fibre content of linings of undergarments, nightwear, hats, ties, trousers and slacks,  and that 
of slee ve linings of jackets and coats (if different from the main lining) need not be marked.  
7.9.2.3  Non-textile material linings of coats, jackets and other garments need not be marked, but  the fibre 
content of linings or waddings of, for example, gloves, foot wear and padded jackets shall  be marked if these 
linings or waddings are described as having, or if it is implied that they have,  warming properties.  
7.9.2.4  An indication of the fibre content of interlinings is not required.  
7.10 Textile products of unspe cified fibre content  
7.10.1  Class  
In the case of any product or part of any product whose fibre content would be impractical to  determine for 
technical reasons, or when information on the fibre content cannot be obtained from  the previous supplier and 
it would be demonstrably impractical for technical reasons to determine  the actual fibre content, the product 
can be classed as a textile product of unknown or unspecified  fibre content or as a textile product of mixed 
fibres  
7.10.2  Marking  
7.10.2.1  When it is  possible to determine the predominant fibre type(s), the generic name(s) of the  fibre 
type(s) shall be marked, by being listed in descending order of dominance, by mass, with or  without an 
indication of their percentages.  
EXAMPLE 1  
A regenerated or a blen ded fabric  contains 40 % acrylic, 35 % polyester and 25 % is  marked as  
a) "40 % acrylic, 35 % polyester, 25 % mixed fibres", or as  
b) "acrylic, polyester, mixed fibres".  
EXAMPLE 2  DUS 426: 2018  
© UNBS 2018  – All rights reserved  11 
 A fabric that contains 45 % cotton and 55 % blended fabric  is marked as  
55 % mixed  fibres, 45 % cotton", or as  
7.10.2.2 When it is impractical to determine the constituting fibre types, the product shall be  marked "exact 
fibre content unknown", or "unspecified fibre content" or "mixed fibres".  
7.11 Textile products composed of two or mo re units or textile components  (excluding 
foundation garments)  
A textile product composed of two or more units or textile components that have different fibre  contents – for 
example a two -piece suit whose jacket and trousers are of different fabrics, or a dress  whose bodice and skirt 
components are of different fabrics (but excluding foundation garments as  given in 7.4) – shall be so marked 
as to state the fibre content of each unit or component. Such  labelling applies to units or components that 
represent 30 % or more of the total mass of the  product, where the mass is taken as excluding the main lining 
and other relevant accessories  (see 8.1). 
8 Determination of actual fibre content  
8.1 Preparation of laboratory sample  
Remove the following from the laborat ory sample, as appropriate:  
a) non-textile parts, selvedges, labels, badges, edgings and trimmings that are not an integral part  of the 
product;  
b) buttons, buckles, accessories, decorations, non -elastic ribbons, elastic threads and elastic bands  that 
are added at specific and limited points of the product;  
c) in the case of textile floor coverings, all components other than the use -surface;  
d) in the case of textile products other than those referred to in (c) above, base fabrics or underlying  
fabrics that do not serv e as a backing for the use -surface; stiffenings, interlinings and canvas  
backings, stitching and assembly threads that do not replace the warp or weft of the fabric;  fillings that 
do not have an insulating function; and linings other than main linings; and  
e) fatty substances, binders, weightings, sizings and dressings, impregnating products, additional  dyeing 
and printing products, and other textile processing products.  
8.2 Procedure  
Determine the actual fibre content of a textile or of a textile product in a ccordance the relevant part(s) of ISO 
1833, as appropriate.  
8.3 Calculation  
Calculate the fibre percentage(s) by applying, to the anhydrous mass of each fibre, the appropriate  
conventional moisture -regain value as given in Annex B.  DUS 426: 2018

 9 Labelling and marking  
9.1 General  
9.1.1 The labelling or marking indicating the fibre content of a textile or of a textile product shall be  clearly 
visible, and no part of this information shall be obscured.  
9.1.2 The trade name or trademark of an undertaking may immediately pr ecede or immediately  follow the 
indication of fibre content. Trade names etc. need not be of the same size lettering as the  generic name.  
9.1.3 The supplier shall be responsible for ensuring that the textile or the textile product is  appropriately 
labelled  or marked (see 9.3) and that the required information is easily accessible to  the prospective 
purchaser when the textile or the textile product is offered or displayed for sale or is  sold.  
NOTE  Textile products that are exempt from fibre -content labelling  are listed in Annex A.  
9.2 Labels  
9.2.1 When a label is to be permanently attached to a textile or to a textile product, the appropriate  fibre-
content information shall either be woven into or be printed onto a label of suitable size and  material such tha t 
the information is clearly legible, and the label material and the information on the  label are capable of 
withstanding the appropriate cleaning treatment throughout the useful life of the  textile or textile product.  
NOTE 1  It is recommended that for qua lity control purposes, the fibre -content marking on the label have a grey scale 
rating for change in colour of not less than 4 -5 after five cleaning treatments carried out in accordance with the care -
labelling instructions for the textile or textile produc t. 
NOTE 2  Statutory requirements for fibre -content labelling are given in the relevant national legislation (see foreword).  
9.2.2 When a label is to be permanently attached to an item of clothing in such a way that the label will be 
in direct contact with the wearer's body, the label shall be manufactured and attached so as to prevent 
discomfort through irritation to the skin, for example scratching.  
9.3 Application of labels or marking  
The appropriate fibre -content information shall be labelled or marked i n one (or more) of the  following ways:  
a) directly on the fabric, i.e. printed on the fabric or woven into the fabric along the selvedge at  regular 
intervals, for example in the case of textile piece -goods;  
b) on a label securely attached to the textile or texti le product, for example a sewn -in label on a  garment 
(as described in 9.2.2);  
c) on the packaging or on a label firmly attached to the packaging;  
d) on a label attached to the textile or textile product in a non -permanent way, for example a swing  ticket 
or a rem ovable adhesive label;  
e) when textiles or textile products (or both) are passed between processors and are not offered for  sale 
to the consumer, labelling may be in the form of a note on, or contained in, the commercial  
documents that accompany the goods, su ch as the invoice, receipt, brochure or pamphlet,  relating to 
the specific textile or textile product; and  
f) when textile products are sold as a complete unit, for example a skirt and top, only one label or  
indication of the fibre content is required, provid ed that the items comprising the complete unit  consist 
of the same fibre content  DUS 426: 2018
