Embodiment 1

[0014] Embodiment 1: The fabric specification is: plain weave fabric of CM50*CM80 / 2T*160*70*60 / 61, and the technical process is as follows:

[0015] Cloth turning: singeing, deboiling, bleaching, mercerizing, liquid ammonia, non-ironing, baking, washing, tentering, shrinking and packing inspection

[0016] Cloth turning process: the front and back are consistent, and the seam is straight and firm;

[0017] Singeing process: Singeing is clean;

[0018] Desizing and scouring process: desizing is clean, the desizing rate reaches over 98%, and the hair effect after scouring reaches 5cm / 5min to ensure the non-ironing effect and hand feeling;

[0019] Bleaching process: the whiteness of the bleached fabric reaches 87 in CIE resin under D65 light source;

[0020] Mercerizing process: mercerizing is sufficient, and the pH value of the cloth surface is 7-9.

[0021] Liquid ammonia finishing process: adopt conventional liquid ammonia finishing, and the pH value of the fabric after li...

Abstract

The invention provides a non-iron finishing method for piece-dyed pure cotton fabric. The non-iron finishing method is characterized by comprising technological processes in sequence as follows: cloth turning, singeing, desizing and scouring, bleaching, mercerizing, liquid ammonia finishing, non-ironing, baking, washing, tentering, pre-shrinking as well as checking and packaging, wherein an intelligent non-iron technology is adopted for the fabric, resin and fibers are subjected to a crosslinking reaction sufficiently, formaldehyde and strength loss caused by resin residues are avoided, strength repair is avoided in a dyeing and finishing process, the content of formaldehyde of a cloth cover can be reduced, and the increase of formaldehyde can be prevented; with the adoption of non-iron finishing, the appearance of the fabric washed 5 times with an AATCC 124 method can reach level 3.2 or higher, and the content of formaldehyde is 60 PPM or lower through testing with a JIS L1041:2011 / 8.1.4B method. The processed fabric is soft and comfortable to wear, is environment-friendly and has an excellent non-iron effect.

Description

technical field [0001] The invention provides a non-ironing finishing method for pure cotton piece dyed fabrics, which belongs to the technical field of textile printing and dyeing. Background technique [0002] Cotton, as a commonly used fiber for clothing, has the advantages of moisture absorption, breathability, antistatic, and comfortable wearing, and is deeply loved by people. However, it also has disadvantages such as poor elasticity, easy to wrinkle, and uncomfortable wearing. Therefore, non-ironing finishing is an important finishing process to improve the wearing performance and added value of cotton fabrics. [0003] However, with the increase of the non-ironing level of the fabric, the tear strength of the fabric decreases, the formaldehyde content of the fabric surface increases, and the formaldehyde increases after the fabric is placed. Therefore, in order to prevent the tearing strength from being damaged and reduce the wearing performance, reduce the formalde...
