Leather substitute prodn. by impregnating textile with chlorhydrin der - by impregnating textile with chlorohydrin deriv. and fixing by means of nitrogen cpd.

摘要

In the parent patent textile flat goods with increased capacity for absorption of water vapour are prepd. by (a) treatment with polymeric binders and impregnation with 6-4 wt. % of glycidyl ethers, and (b) drying the impregnated textile at increased temp. while fixing the glycidyl cpd. by means of cps. contg. NH gps. In this addn. the glycidyl ethers are replaced by cpds. of formula (I) R -( O (CH2CH2O)p-CH2-CH(OH) -CH2Cl )-q where R is a 2-13C (un)branched 2-6 valent (cyclo)aliphatic hydrocarbon gp.; p = 1-30; and q = 2-6. Conversion prods. of (I) with cpds. contg. NH gps. may be used in place of (I). (I) are very stable and are cheap. The treated textile is a synthetic leather.
