Semi-material dyeing technology of silk-cotton interweaving garment material

A technology of silk cotton and clothing, which is applied in the field of half-material dyeing process of silk and cotton interwoven clothing fabrics. It can solve the problems that the performance requirements of silk and cotton interwoven clothing fabrics cannot be met, the color of silk and cotton interwoven fabrics is not bright enough, and the dyeing time is long. Process and color control is simple and easy, the visual effect has no sense of white fog, and avoids the effect of whitening cotton fibers

Problems solved by technology

For silk cotton products dyed with reactive dyes, the color depth of real silk fiber is better than that of cotton fiber, especially in dark blue and black series. The depth of real silk fiber is 50% deeper than that of cotton fiber. Low strength, it is difficult to achieve the ideal dyeing effect
Silk-cotton interwoven fabrics are dyed in dark colors. The existing technology always has the problem that the color on the silk fiber is dark and the color on the cotton is light, so that the cloth surface is not plump, the cotton is white, and the overall effect is not high-end.
The whiteness of the cotton fiber increases the brightness of the silk-cotton interwoven fabric. When viewed visually, the surface of the silk-cotton interwoven fabric seems to be covered with a layer of white mist, which makes the overall color of the silk-cotton interwoven fabric not bright enough.
Especially when silk-cotton interwoven fabrics are used as silk-cotton interwoven clothing fabrics, the requirements for color fastness and brightness saturation of colors are relatively high, and the performance requirements of silk-cotton interwoven clothing fabrics cannot be met with the existing technology
[0005] Finally, although there is a design in the prior art that uses the two-bath method for dyeing, the prior art requires repeated washing, soaping, and water washing between the two baths, which is a serious waste of water resources and time-consuming and labor-intensive; the two-bath method requires Immersing the silk-cotton interwoven fabric twice in the dyeing liquor results in high wastewater discharge and increases production costs; the dyeing time in the second bath is too long, reducing work efficiency

Abstract

The invention provides a semi-material dyeing technology of a silk-cotton interweaving garment material, and belongs to the technical field of silk-cotton goods dyeing. The semi-material dyeing technology comprises the following steps: firstly respectively preparing a first coloring agent and a second coloring agent; then pre-processing a silk-cotton interweaving garment material by adopting one bath process in a dyeing process, keeping temperature at 55-65 DEG C, and dyeing the silk-cotton interweaving garment material at a constant temperature by adopting a jig dyeing method; when dyeing for one half of the total dyeing time, adding 14-36g / L of sodium carbonate to the first coloring agent, uniformly stirring, then adding the second coloring agent to the first coloring agent, keeping temperature at 55-65 DEG C, dyeing at a constant temperature by adopting a jig dyeing method till the total dyeing time is over, and discharging waste liquid, wherein the total dyeing time is 60-200 minutes. The silk-cotton interweaving garment material obtained by adopting the method has the advantages that the dye up-take of silk fibers and cotton fibers is consistent, the color fastness of cotton is improved, the fabric obtained by adopting the method has bright integral color without exposed white, and the color fastness of the fabric is high.

Description

technical field [0001] The invention belongs to the technical field of dyeing of silk-cotton interwoven fabrics, and in particular relates to a half-material dyeing process of silk-cotton interwoven fabrics. Background technique [0002] Silk-cotton blended fabric integrates the excellent properties of silk fiber and cotton fiber. Silk fiber has the reputation of "fiber queen" since ancient times, and modern people endow it with "health care fiber". It belongs to protein fiber and contains 18 kinds of amino acids necessary for human body. It has the characteristics of luxury, smoothness and good luster. The fiber is a natural fiber, which has the characteristics of softness, moisture absorption, warmth retention, and good air permeability. Silk-cotton interwoven fabrics can be dyed to obtain silk-cotton interwoven clothing fabrics. Silk-cotton interwoven clothing fabric is currently the most respected high-end clothing fabric. [0003] In the prior art, there are the foll...
