| abstract | Crape effects are produced on fabrics comprising highly twisted crape threads and more particularly on fabrics comprising crape threads made of or containing cotton or other natural cellulose fibres, or artificial filaments such as regenerated cellulose or cellulose acetate or other cellulose esters or ethers, by treating the threads before or after twisting to a high degree with a substance adapted to cause swelling of the material of the threads. Examples of such swelling agents are ammonium, calcium, or other thiocyanates, or zinc halides, sodium iodide, and calcium chloride or nitrate, acetic, lactic, aromatic-sulphonic, or other organic acids, methyl, ethyl, or other alcohols, acetones methyl-ethyl-ketone, methyl acetate, ethyl lactate, and amines such as aniline, any of which are suitable for cellulose esters or ethers while the inorganic compounds are more suitable for cotton or regenerated cellulosic artificial silk. On scouring fabrics containing threads so treated craping is effected. As an example, a fabric comprising threads of cellulose acetate which have been treated with absolute ethyl alcohol or with acetic acid applied in a benzene solution is subjected to the action of water whereupon craping is effected. The swelling agents may be incorporated in the filaments or fibres during processes of their manufacture, suitable swelling agents for incorporation being calcium chloride or nitrate, zinc chloride, sodium iodide and ammonium, calcium or other thiocyanate, which agents may be applied in acetone or other suitable solutions. Where the swelling agents have too strong a solvent action on the materials treated, their use with suitable diluents either as vapour, liquid, or gas is preferred. Suitable diluents are aliphatic or aromatic hydrocarbons such as petroleum ether, benzene, or toluene. Soaps, wetting agents, salts, acids, or other substances which modify the craping action of the water may be added thereto, and the craping treatment may be combined with the dyeing of the fabric. Softening of the filaments should be avoided. The conditions necessary in the process described in Specification 348,589, for treating a sized craped thread or fabric should be observed, and with that process the present process may be combined. The highly twisted crape threads may be used either as warp or weft. In an example, cellulose acetate yarn is immersed in commercial dichlorethylene, twisted to form a crape thread which is then woven as a warp, two picks of left-hand twist alternating with two picks of right-hand twist. The fabric so obtained, on scouring in an aqueous bath, exhibits crape effects. Specifications 224,642 and 226,256, [both in Class 142 (iv), Woven fabrics &c.], are also referred to. |
