Title: Improvements in the treatment of cellulosic textile materials
IPC: D06M15/71
Filed: 1964-10-27
Abstract: Fabrics and fibre-fleeces of cellulosic fibres, e.g regenerated cellulose, are crease-proofed and/or waterproofed by impregnating them an aqueous solution containing a crease-proofing and/or waterproofing agent subjecting them to migration-free moisture extraction until a moisture content of 25 - 40% by weight of the bone dry fabric is attained and then subjecting them to a heat treatment for 1-3 minutes.  The migration-free moisture extraction may be carried out by drying slowly so that uniform impregnation of the fibres with the treating medium is obtained.  The treatment may be preceded by a soda lyemercerising operation with complete shrinkage in warp and weft of 15 - 30% reduction in both directions with subsequent severe stretching in a warp stretching machine and weft stretching in a full width stenter.  The mercerising treatment may be combined with a desizing, bucking and bleaching treatment with completely relaxed web guidance for 10 - 15 minutes in air-free water vapour.  The materials may also be subjected to an extra wash process in which during the entire passage through the wash and post-treatment process a warp tension load of 5 - 10 kg according to the kind if material is not exceeded.  The supplementary wash treatment may be combined with a steam treatment in air-free water vapour.  The subsequent heat treatment may be carried out on a continuous throughgoing ring winder.

Title: Treatment of cellulosic fabrics
IPC: D06M13/175
Filed: 1959-12-24
Abstract: Cellulosic fabrics, e.g. cotton and regenerated cellulose are crease-proofed and shrink-proofed by treating them with a thiodiglycol of the formula <FORM:0935421/IV(a)/1> in which R is H or CH3, or an ester or ether derivative thereof with a C1-C19 alkanoic acid or C1-C18 alkanol and then curing them to effect bonding of the thiodiglycol or derivative thereof to the cellulosic fibres.  The fabrics may be treated with aqueous solutions, dispersions or emulsions containing 1-30% by weight of the thiodiglycol or derivative thereof and 0,2-5% based on the weight of the thiodiglycol or derivative thereof of an acid catalyst.  Suitable catalysts are phosphoric acid, sodium and ammonium bisulphates and the salts of metals of Group Ib, II, IIIb, IV and VIII of the Periodic Table having an atomic weight of at least 12 and acids having the formula Ha(XY6) where thio hydrogen, a is an integer which depends upon the valence of the complex ion and may have a value of 1, 2 or 3, X is boron, silicon, sulphur or chlorine in which the valence state is from 3-7, Y is fluorine or oxygen and b is 4 or 6, e.g. zinc, lead, copper and magnesium perchlorates and fluoborates, aluminium and copper sulphates and magnesium, zinc and copper fluosilicates. The treating composition may also contain synthetic polymer latices and aminoplast resins or precondensates.  After impregnation excess liquid may be removed from the fabrics by squeezing, shaking or centrifuging and they may then be dried at room temperature or at a temperature of 140 DEG F. or above and then cured by heating to a higher temperature.  Alternatively, after the impregnation, the fabrics may be cured by heating to 212 DEG -450 DEG F. or higher for 1-30 minutes or more without the preliminary low-temperature drying or a flash cure at 700 DEG -750 DEG F. for 1-20 seconds may be used.

Abstract: 1463978 Built laundry composition PROCTER & GAMBLE CO 18 Sept 1974 [19 Sept 1973] 43969/73 Addition to 1401726 Heading C5D In a process for making a built laundry detergent composition comprising: (A) granular particles which comprise (i) from 30 to 80% by weight of the granular particles of a soap compound; and (ii) from 1 to 30% by weight of the granular particles of a curd-dispersing agent; and (B) an impalpable smectite-type clay having an ion exchange capacity of at least about 50 meg./100g. of clay, attached to the surfaces of the granular particles, the compositions having a weight ratio of granular particles to smectite clay in the range from 20 : 1 to 3 : 1, a moving bed of a  particulate carrier (as defined), optionally also containing some or all of the clay for the composition, is sprayed with a liquid agglomerating agent or a suspension therein of the clay or of the rest, if any, of the clay for the composition, to form free flowing agglomerates comprising said clay and said carrier, and thereafter said agglomerates are dry mixed with other particulate components, if any, of the composition. The carrier may be sodium or potassium tripolyphosphates, tetrasodium and disodium pyrophosphates, carbonates, sulphates and borates or spray-dried built soap-based detergent granules. The liquid agglomerating agent may be water, an aqueous electrolyte or a C 10-24  fatty acid mixture. When the agglomerating agent is aqueous, the particulate carrier is or contains an incompletely hydrated hydratable salt, which may be inorganic. A suspension of clay in a C 10-24  fatty acid may be sprayed directly on to a spray-dried soap composition, and the resultant powder mixed with sodium perborate and sodium tripolyphosphate. The carrier is such that the clay can be bonded by physical bonding to the particles of carrier.

The pressure is maintained on the lubricant by a piston 32 urged by a spring 31 and slidable along the tube in a chamber 2. The interior of the string is connected by channel 4 to the chamber above the piston so that the piston and the lubricant are also subjected to the pressure within the string. The seal comprises a rubber ring 16 vulcanized to a metal ring 35 and having outer surfaces coated with a graphited layer 36. In a modification (Fig. 8, not shown), the seal comprises a rubber ring 38 vulcanized to metal rings 35, 37, the ring 37 being adapted to bear against a ring 39 of rubber or anti-friction material fixed to the cutter. The ring 37 has a rubber section inserted in its circumference, and may have a straight limb adapted to bear against the ring 39. The seal may be reinforced with metal, nylon, silk or cotton, and may contain silicon or fluorine.

Heading D1N A carding machine has means for gradually changing the speed of its feed and delivery elements. The invention has particular application to an automatic sliver production line as described in Specification 910, 759 where it may reduce the amount of waste consequent on very rapid stoppage of the drawbox and coiler section of the apparatus. The drawbox and coiler sections are indicated at DB and CO and the shaft driving the carding section at 22. A gear reduction motor GRM drives the input shaft 21 at a low speed through a free wheel unit FWU. An alternative drive to the input shaft 21 is provided by the main motor MM through a variable speed gear CG controlled by the motor CM and so arranged that its lowest speed is slightly lower than the speed imparted to the shaft 21 by the motor GRM. If it is necessary to stop the drawbox quickly, a clutch 23 is de-energized and a brake 25 applied. Deceleration of the carding machine then follows deenergization of a clutch 24. Specification 910,761 also is referred to.
