Abstract

The present application relates to the technical field of garment finishing, and specifically discloses a non-iron finishing process for shirts. The non-iron finishing process of shirts includes the following steps: S1 pre-cleaning; S2 chitosan finishing; S3 epoxy resin finishing: immerse the cotton shirts finished with S2 chitosan into the epoxy resin finishing solution, one dipping and one rolling, and the immersion temperature is 60°C ‑80℃, dipping time 20‑30min, residual ratio 90%, after taking out, pre-bake at 90‑100℃ for 4‑6min, then bake at 170‑190℃ for 90‑120s, then wash with water and dry; S4 Pressing and shaping: Pressing and shaping each part of the cotton shirt finished with S3 epoxy resin, the pressing temperature is 130-150°C, to obtain a non-iron shirt. The present application adopts the method of finishing with chitosan first and then finishing with epoxy resin, so as to improve the whiteness of cotton shirts and the resistance to ironing and washing.

Description

technical field [0001] The present application relates to the field of garment finishing, more specifically, it relates to a non-iron finishing process for shirts. Background technique [0002] Cotton shirts have the advantages of soft hand feel, good moisture absorption and air permeability, etc., but they are easy to wrinkle and need to be ironed after washing, which is troublesome. In order to avoid the trouble of ironing, iron-free shirts are currently very popular in the market. A non-iron shirt is a 100% cotton textured shirt that can be restored flat after ordinary washing without ironing or a little ironing. The non-iron finishing of shirts mostly uses the initial shrinkage of amide and formaldehyde. Although a higher non-iron grade can be obtained, it does not conform to the current environmental protection concept. [0003] At present, many kinds of formaldehyde-free finishing agents have been developed, such as: chitosan finishing agent, silicone finishing agent...
