Problems solved by technology

Although this method has the characteristics of not producing formaldehyde in the whole shirt production process, its disadvantages are that the method has high cost and complicated process, and does not fundamentally solve the problem of significant decline in the strength of cotton fabrics after non-ironing finishing
However, its disadvantages are that the process of this method is relatively complicated, and the amount of reagents is relatively large, which does not fundamentally solve the problem of fabric strength decline.

Embodiment 1

[0039] According to the above process steps: select the scouring and non-ironing cotton fabric as the fabric to be finished, place the scouring and non-ironing cotton fabric in liquid ammonia for padding liquid ammonia treatment, wherein the padding time is 0.1 minute , the paddle pressure is 0.2Mpa, and the fabric pretension is 0.1kg / cm 3 . Put the cotton fabrics treated with liquid ammonia in N-methylol resin for heavy-duty non-ironing finishing, wherein the cotton fabrics after padding with N-methylol resin are pre-dried at 40°C and baked at 160°C for later use . Put the cotton fabric after heavy non-iron finishing in liquid ammonia for heavy liquid ammonia finishing, wherein the padding time is 30 minutes, the padding pressure is 0.05Mpa, and the fabric pretension is 0.5kg / cm 3 .

Embodiment 2

[0041] According to the above process steps: select the cotton fabric after scouring, bleaching and non-ironing as the fabric to be finished, place the cotton fabric after scouring, bleaching and non-ironing in liquid ammonia for padding liquid ammonia treatment, wherein, padding The time is 30 minutes, the padding pressure is 0.05Mpa, and the fabric pretension is 0.5kg / cm 3 . Put the cotton fabrics treated with liquid ammonia in N-methylol resin for heavy-duty non-ironing finishing, wherein the cotton fabrics after padding with N-methylol resin are pre-dried at 60°C and baked at 120°C for later use . Put the cotton fabric after heavy non-ironing finishing in liquid ammonia for heavy liquid ammonia finishing, wherein the padding time is 0.1 minute, the padding pressure is 0.2Mpa, and the fabric pretension is 0.1kg / cm 3 .

Embodiment 3

[0043] According to the above process steps: select the cotton fabric after scouring, bleaching, mercerizing and non-ironing as the fabric to be finished, place the cotton fabric after scouring, bleaching, mercerizing and non-ironing in liquid ammonia for padding liquid ammonia treatment, Among them, the padding time is 15 minutes, the padding pressure is 0.1Mpa, and the fabric pre-tension is 0.3kg / cm 3 . Put the cotton fabric treated with liquid ammonia in N-methylol resin for heavy non-ironing finishing, roll the cotton fabric after padding with N-methylol resin, and store it at 24°C for 48 hours before use. Put the cotton fabric after heavy non-ironing finishing in liquid ammonia for heavy liquid ammonia finishing, wherein the padding time is 10 minutes, the padding pressure is 0.15Mpa, and the fabric pretension is 0.5kg / cm 3 .

Abstract

The invention relates to an anti-crease finishing method for improving the strength and the hand feeling of a cotton fabric, and belongs to a textile printing and dyeing post-finishing technology. Thepurpose of the invention is to provide the method for changing the anti-crease finishing process of the cotton fabric. A non-iron finished cotton fabric is sequentially subjected to liquid ammonia finishing, non-iron finishing and liquid ammonia finishing, so the anti-crease effect of the cotton fabric is greatly improved, and the strength and the hand feeling of the cotton fabric are improved. The method fully shows the original advantages of the cotton fabric, and also can modify and optimize the cotton fabric, increase the creasy recovery angle of the cotton fabric, increase the strength of the cotton fabric, improve the flatness and improve the hand feeling of the cotton fabric, so the non-ironing effect is achieved, and the quality of the cotton fabric and the grade of the obtained product are greatly improved. The method has a simple process and a good anti-crease effect, is a clean production technology meeting environmental protection requirements, and has extremely high social and economic benefits.

Description

technical field [0001] The invention relates to an anti-wrinkle finishing method for improving the strength and hand feeling of cotton fabrics, which belongs to the finishing technology of textile printing and dyeing. Background technique [0002] In the traditional wrinkle-resistant finishing of cotton fabrics, the method of liquid ammonia finishing and non-ironing finishing is generally adopted. Although liquid ammonia finishing can expand the spacing between cellulose molecular chains, improve the roundness of cotton fibers, increase the hydrophilicity and air permeability of cotton fibers, improve the softness of cotton fabrics, and protect cotton fabrics to a certain extent. The strength of the fabric. However, before padding the non-iron finishing agent, it is usually necessary to keep the pH value of the cotton fabric surface in the range of 6.5 to 7. Since the cotton fiber is alkali-resistant and not acid-resistant, a series of problems will appear after the cotton ...
