Problems solved by technology

The warp and weft density of these two heavyweight silk twills is too high, the fabric is compact, and the gaps between fibers are small. During the printing process, the printing paste is not easy to penetrate from the front to the back of the silk twill through the gaps between the fibers. As a result, the color difference between the front and back of the silk twill is relatively large, and the printing is not clear

Embodiment 1

[0039] A printing color paste, comprising the following components by mass fraction:

[0040] Printing paste 8%;

[0041] Urea 10%;

[0042] Dyes, the dyes used and the percentage content are shown in Table 1 below;

[0043] Water 79.92%;

[0044] The printing paste is prepared from 20% modified guar gum seed extract, 1% preservative, and 79% water.

[0045] The preparation method of the printing paste: after mixing the modified guar gum seed extract, preservative and water according to the mass fraction, the mixer stirred for 45 minutes, and then added 5% H 2 SO 4 , after fully mixing, hydrolyze at 70°C for 2 hours, add NaOH to neutralize until the pH is 6.5-7, and obtain a printing paste with a molecular weight of 10,000-15,000 and a paste rate of 18%-20%, which can be directly used to prepare printing colors Paste, the printing paste viscosity of modulation is 4000CPS.

Abstract

The invention discloses printing color paste. The printing color paste comprises the following components in parts by mass: 8%-12% of a printing paste material, 8%-10% of urea, 0.01%-5% of dye, and the balance being water, wherein the range of the dye molecular weight is 500-800. The printing paste material is prepared from the following components in percentage by mass: 18-20% of a modified guar gum seed extract, 0.8-1.2% of a preservative and the balance being water. The invention also provides a printing silk twill production technology comprising the following steps: weaving silk twill, carrying out refinement treatment on the silk twill, printing the silk twill by adopting the printing paste, steaming, rinsing, drying, fixing color, tentering and thermosetting. By the improvement of the weaving process and the printing paste, the heavy printing silk twill prepared by adopting the printing silk twill production technology is delicate in pattern, is good in printing paste permeation, and is clear in color and pattern in front and back surfaces.

Description

technical field [0001] The invention relates to a printing color paste and a production process of printed silk twill, which can be used to prepare heavy printed silk twill. Background technique [0002] Silk fabrics are fine and smooth, with soft luster, light and thin texture, soft and elastic hand feeling, strong hygroscopicity, gorgeous and noble, and good for human health. They can be made into clothing, decorations, interior products, handicrafts, etc. Heavyweight silk is made of twice the amount of silk of ordinary silk fabrics, and is spun by special techniques. It has elegant appearance, soft luster and comfortable wearing. In addition to the characteristics of ordinary silk fabrics, heavy silk also has the characteristics of no shrinkage, crispness, easy finishing, and not easy to scratch. The fabric weight is greater than 40g / m 2 , the fabric is dense and thick, soft and smooth to the touch, strong drape, and elegant in quality. It is not only an ideal fabric fo...
