Problems solved by technology

[0004] At present, the most important way to make fabrics anti-wrinkle and non-ironing effect is to add polyurethane, but there are two disadvantages in polyurethane finishing process: (1) The formaldehyde content produced is high, which is not conducive to human health; (2) The strength of the fabric is seriously damaged, The strength is reduced by more than 30%, and it is easy to wear and tear due to strong damage in the non-ironing finishing collar, trouser seam and other parts, thus shortening the service life of the clothes

Embodiment Construction

[0014] The present invention will be further described in conjunction with embodiment now.

[0015] The present invention is a non-ironing process of epoxy resin, which is carried out according to the following steps: step 1, put the pretreated fabric into the finishing working solution for 2 times of padding, and the excess rate of padding for the first time is 75%. -80%, the speed of the padding machine is 20 m / min, and the excess rate of padding for the second time is 68-70%, and the speed of the padding machine is 60 m / min; Step 2, the fabric after padding is put into the drawing Stenter drying is carried out in the tenter dryer. The tenter dryer is set in eight drying rooms. The temperature of the first two drying rooms is set at 80°C, and the temperature of the last six drying rooms is set at 120°C. The speed of the stenter dryer is 20 m / min. After the fabric is stenter dried, it is dropped.

[0016] The finishing working solution is composed of 30 grams of hydrophilic...

Abstract

The invention provides a non-ironing process capable of searching formaldehyde content and improving fabric strength aiming at shortcomings of the prior art. A fabric is put into a finishing working solution to be padded for two times and then is put into a tentering dryer to be subjected to tentering drying. Compared with the prior art, according to the invention, hydrophilic silicone softener is adopted to change the problem that the hand feeling of a fabric treated by adopting epoxy resin is hard, and the finished fabric is soft in hand feeling. The finishing effect of the fabric after non-ironing finishing can reach a good effect, namely, the flatness reaches more than or equal to 3.5, the formaldehyde content is zero, furthermore, the strength is improved by more than or equal to 20%, the situation that clothes is worn due to forcible damage is improved, and the life of the clothes is prolonged.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to an epoxy resin non-ironing process. Background technique [0002] For a long time, pure cotton fabric has the advantages of good air permeability, strong hygroscopicity, soft hand feeling and comfortable wearing, and has been welcomed by consumers. But the clothes of pure cotton fabric are easy to wrinkle, not crisp in wearing and washing, and the clothes that wrinkle-prone pure cotton fabric is made have influenced people's attractive in appearance. Apparently, the wrinkle-prone nature of pure cotton fabrics significantly affects the breadth of use of the fabric. [0003] Therefore, it is an important and broad field of fabric dyeing and finishing to vigorously develop and develop various anti-wrinkle finishing agents and strive to improve the quantity and quality of anti-wrinkle finishing. The anti-wrinkle finishing of cotton fabrics has a history of nearly a hundred years. ...
