Use of modified fatty amines for preventing deposition of low molecular weight by-products on textile materials

摘要

The use of modified fatty amines for reducing or preventing the deposition of low-mol. wt. by-products from polyester fibre production on textile materials made of polyester fibres or mixtures of these with other fibres is claimed. These amines have the formula R-NR3-(R1-O)n-R2 (I), in which R = 9-24C alkyl or acyl; R1 = 2-4C alkylene; R2 = H, or 1-4C alkyl or acyl; R3 = H or (R1-O)m; n, m = 2-100; the groups (R1-O) can be the same or different in (R1-O)n and in (R1-O)m. Also claimed is (i) a preparation containing (A) 3-50 wt% compound (1), (B) 2-10 wt% dodecylbenzene-sulphonic acid, and optionally other components; (ii) a method for reducing or preventing the deposition of low- mol. wt. by-products as above on polyester-containing fibre material, by using a preparation as in (i).
