Abstract

The invention belongs to the technical field of textiles, and particularly relates to a preparation method of a phenolic yellowing resistant white chinlon non-ironing fabric. Desizing, pre-tentering,dry shaping, non-ironing, padding, jig dyeing, tentering and pre-shrinking are performed to obtain the fabric, wherein an anti-yellowing finishing agent is added in the pre-tentering process, the non-ironing temperature is 155-165 DEG C, and an anti-phenolic yellowing agent is added in the jig dyeing process. Compared with the conventional white chinlon fabric, the white chinlon non-ironing fabricobtained by the method adopts a high-temperature non-ironing process, has the characteristics of good non-ironing property and washability, and is padded and bleached by using an Ostbook stacking method according to the whiteness requirement, so that the stability of the whiteness of the fabric is improved. The anti-phenolic yellowing agent is added in the jig dyeing process, and a weak cation softener with small influences on yellowing is used for tentering, so that the hand feeling of the fabric is improved, the anti-phenolic yellowing fastness of the fabric is not influenced, the anti-phenolic yellowing fastness of the fabric reaches the grade 4 or above, and the requirement for high quality of high-grade fabrics can be met.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a preparation method of an anti-phenol yellowing white nylon non-ironing fabric. Background technique [0002] Nylon non-iron fabrics have good non-ironing properties, good elasticity, comfort and soft touch, so they are loved by people. However, during the processing, storage and transportation of textiles, due to the reaction of the antioxidant BHT contained in the polyethylene polymer material of the packaging material with nitrogen oxides, obvious yellowing will occur under external packaging and humid and hot conditions, resulting in phenol yellow Change. For products containing spandex after high temperature setting, yellowing is more likely to occur, affecting appearance, strength and wearing performance, especially white fabrics, affecting the quality of fabrics. [0003] Chinese patent CN 105821657 A discloses a non-ironing fabric and its preparation metho...
