Problems solved by technology

[0003] Generally, you need to add dry cleaning agents such as petroleum or tetrachlorethylene with outstanding performance during dry cleaning. For light-colored fabrics, it may be within the qualified standard, but medium and dark-colored fabrics may not be able to meet the standard, especially the elasticity of spandex. For fabrics, the color fastness to dry cleaning measured according to the JIS L0860 standard often cannot reach the qualified standard of grade 3 or above. Even if it is strengthened by washing or color fixation, it may be possible to achieve the qualified value of grade 3 for dry cleaning discoloration and dry cleaning staining. However, for dry cleaning liquid pollution items, it often only reaches level 1-2 or level 2
[0004] In addition, although some dye manufacturers have successively carried out a series of product innovations for the dry cleaning project, and improved the dry cleaning fastness by using special dyes, these dyes are often more expensive, and the color stability is not as good as that of conventional dyes. good color stability

Embodiment 1

[0024] The warp yarn is made of 150D polyester-spandex covered yarn, and the weft yarn is made of 32S viscose spandex covered yarn, in which the spandex content is 10.5%. The medium-dark fabric of the present invention is obtained through the following steps: 135°C*60min disperse dyeing→90°C*30min alkaline reduction water washing (caustic soda 3g / L, hydrosulfite 3g / L)→170°C drying and setting→80°C*30min Acid reducing water washing (glacial acetic acid 2g / L, acid reducing agent 2g / L) → 60°C*60min reactive dyeing → 180°C finishing and setting. The performance parameters of the obtained fabric are shown in Table 1.

Embodiment 2

[0026] The warp and weft yarns are all made of 75D polyester-spandex covered yarn woven gray fabric, of which the spandex content is 12.2%. The medium-dark fabric of the present invention is obtained through the following steps: 135°C*60min disperse dyeing→90°C*30min alkaline reduction water washing (caustic soda 3g / L, hydrosulfite 3g / L)→170°C drying and setting→80°C*30min Acid reduction water washing (glacial acetic acid 2g / L, acid reducing agent 2g / L) → 180°C finishing and setting. The performance parameters of the obtained fabric are shown in Table 1.

Embodiment 3

[0028] The warp yarn is made of 75D polyester-spandex covered yarn, and the weft yarn is made of 50D polyester-spandex covered yarn, in which the spandex content is 18.2%. The medium-dark fabric of the present invention is obtained through the following steps: 135°C*60min disperse dyeing→90°C*30min alkaline reduction water washing (caustic soda 3g / L, hydrosulfite 5g / L)→170°C drying and setting→80°C*30min Acid reduction water washing (glacial acetic acid 3g / L, acid reducing agent 3g / L) → 185°C finishing and setting. The performance parameters of the obtained fabric are shown in Table 1.

Abstract

The invention discloses a medium-dark fabric and a production method thereof. The fabric is a woven or knitted fabric containing at least polyester and spandex, wherein the content of spandex fiber is 3% to 20%, and the L value of the fabric is 12 to 65. The dry cleaning of the fabric measured according to JIS L 0860 standard In color fastness, discoloration is above level 3-4, staining is above level 3, and lotion pollution is above level 3. The dry cleaning color fastness of medium-dark fabrics is effectively improved by adding drying and setting and acid washing after dyeing, and the improvement effect is stabilized by controlling the finishing and setting temperature. The resulting fabric has excellent dry cleaning color fastness.

Description

technical field [0001] The invention relates to a medium-dark color fabric and a production method thereof, in particular to a medium-dark elastic fabric with high color fastness to dry cleaning and a production method thereof. Background technique [0002] As we all know, the initial color of most clothing fabrics is relatively bright, but the color will change after friction or sun exposure. In order to solve these color fastness problems, people have proposed corresponding solutions. For example, in CN200810062408.6, the color fastness to rubbing of knitted fabrics made of polyester and spandex is ensured through the good dyeability and dyeing permeability of cationic polyester. As another example, in CN201310581010.4, the light fastness of fabrics is improved by using anti-ultraviolet additives during finishing and setting. But all fail to solve the dry-cleaning color fastness problem of fabric in above-mentioned patent. [0003] Generally, you need to add dry cleaning...
