Problems solved by technology

[0002] Cotton, as one of the representatives of natural fibers, has the characteristics of good air permeability and natural comfort, but the main disadvantage of cotton is that it is easy to wrinkle and shrink after washing; so in order to improve this shortcoming, the wrinkle resistance finishing of pure cotton fabrics appears Especially important, however, the fabrics finished by the previous non-ironing finishing method have poor warp and weft elasticity, poor seamability of the fabric, and poor wearing comfort

Embodiment 1

[0024] The fabric specification is: CM40*CPT36*160*66*61 / 62 plain weave fabric, and the non-ironing finishing process of the fabric is as follows:

[0025] 1. Fabric preparation: the desizing rate of the gray fabric reaches over 98%, and the hair effect after scouring reaches 5cm / 5min to ensure the non-ironing effect and hand feeling. The whiteness of the bleached fabric under the D65 light source has a CIE value of 87, which is alkali mercerized. It is required to be fully mercerized, and the pH value of the cloth surface is between 6 and 7.

[0026] 2. The mercerizing process is carried out on the mercerizing machine. Firstly, alkali rolling is carried out. The auxiliary agent used in the alkali rolling is 32Be caustic soda. The pH value of the cloth surface is controlled at 6-7.

[0027] 3. Liquid ammonia finishing: adopt conventional liquid ammonia finishing, and the pH value of the fabric after liquid ammonia finishing is set at 6.

[0028] 4. Pre-softening: carried out...

Embodiment 2

[0037] The specifications of the fabric are: CM50*CPT50*140*90*57 / 58 twill fabric, and the non-ironing finishing process of the fabric is as follows:

[0038] 1. Fabric preparation: the desizing rate of the gray fabric reaches over 98%, and the hair effect after scouring reaches 5cm / 5min to ensure the non-ironing effect and hand feeling. The whiteness of the bleached fabric under the D65 light source has a CIE value of 84, which is alkali mercerized. It is required to be fully mercerized, and the pH value of the cloth surface is between 6 and 7.

[0039] 2. The mercerizing process is carried out on a mercerizing machine. First, alkali rolling is carried out, and the auxiliary agent used in rolling alkali is 32Be caustic soda. The pH value of the cloth surface is controlled at 6-7.

[0040] 3. Liquid ammonia finishing: adopt conventional liquid ammonia finishing, and the pH value of the fabric after liquid ammonia finishing is set at 7.

[0041] 4. Pre-softening: carried out ...

Abstract

The invention belongs to the technical field of textile printing and dyeing, and in particular relates to a high-elastic non-ironing finishing method for pure cotton fabric. The method includes the following steps: fabrics preparation, mercerized finish, liquid ammonia finish, pre-softening, applying of a moist crosslinking agent, pre-shrinkage, storage reaction, washing, stretching setting and second pre-shrinkage. A stenter is used for applying the moist crosslinking agent, the moist crosslinking agent comprises CMC, a catalyst, a fiber protecting agent, a softener, hydrochloric acid, and the rest of water. The temperature of a drying room is controlled at 80 to 100 DEG C, the temperature of the fabric is controlled between 35 to 40 DEG C, the falling cloth humidity is 6-8%, and the fabric is rolled at the falling position. The treated fabric has non-ironing level reaching the AATCC124 standard 4.0 or above of the U.S.A, formaldehyde content below 75ppm, warp elasticity of 4% above the ASTM D3107-2011 standard, weft elastic elongation of 17% above the ASTM D3107 standard, and has ensured sewability and non-ironing performance.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and in particular relates to a high-elastic non-ironing finishing method for pure cotton fabrics. Background technique [0002] Cotton, as one of the representatives of natural fibers, has the characteristics of good air permeability and natural comfort, but the main disadvantage of cotton is that it is easy to wrinkle and shrink after washing; so in order to improve this shortcoming, the wrinkle resistance finishing of pure cotton fabrics appears It is particularly important, but, through the fabric after the non-ironing finishing method in the past, the warp and weft elasticity is relatively poor, the seamability of the fabric is relatively poor, and the wearing comfort is relatively poor. Contents of the invention [0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a high-elastic non-ironing finishing method for pure c...
