Shirt non-ironing finishing process

Abstract

The invention relates to the technical field of ready-made clothes finishing, and particularly discloses a shirt non-ironing finishing process. The shirt non-ironing finishing process comprises the following steps of S1, performing pre-cleaning; S2, performing chitosan finishing; S3, performing epoxy resin finishing: immersing a cotton shirt subjected to chitosan finishing in the step S2 in epoxy resin finishing liquid, performing once dipping and once rolling at the dipping temperature of 60-80 DEG C for 20-30 min to make the liquid entrainment rate equal to 90%, taking out the cotton shirt, pre-drying the cotton shirt at 90-100 DEG C for 4-6 min, baking the cotton shirt at 170-190 DEG C for 90-120 s, washing the cotton shirt with clear water, and drying the cotton shirt; and S4, performing pressing and shaping: performing pressing and shaping on each part of the cotton shirt subjected to epoxy resin finishing in the step S3 at the pressing temperature of 130-150 DEG C to obtain a non-ironing shirt. According to the invention, chitosan finishing and epoxy resin finishing are carried out in sequence, so that the whiteness and non-ironing washability of the cotton shirt are improved.

Description

technical field

[0001] This application relates to the field of garment finishing, more specifically, it relates to a shirt non-ironing finishing process. Background technique

[0002] Cotton shirts have the advantages of soft touch, good hygroscopicity and air permeability, but they are easy to wrinkle, and need to be ironed after washing, which is troublesome. In order to avoid the trouble of ironing, non-iron shirts are very popular in the market at present. Non-iron shirts refer to shirts made of 100% pure cotton, which can be restored to flatness without ironing or slight ironing after ordinary washing. The non-iron finishing of shirts mostly uses the initial shrinkage of amide and formaldehyde. Although it can obtain a high level of non-ironing, it does not meet 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, epoxy resi...

Examples

preparation example 1

[0045] The preparation process of the chitosan finishing solution is as follows: 1.2 parts of chitosan, 6 parts of citric acid, 0.05 parts of sodium hypophosphite, 0.12 parts of emulsifier OP-10 and 100 parts of water were mixed and stirred evenly.

preparation example 2

[0047] The preparation process of the chitosan finishing liquid is as follows: 1.5 parts of chitosan, 8 parts of citric acid, 0.08 parts of sodium hypophosphite, 0.15 parts of emulsifier OP-10 and 120 parts of water are mixed and stirred evenly.

preparation example 3

[0049] The preparation process of the chitosan finishing solution is as follows: 1.3 parts of chitosan, 7 parts of citric acid, 0.06 parts of sodium hypophosphite, 0.14 parts of emulsifier OP-10 and 110 parts of water were mixed and stirred evenly.
