Embodiment 1

[0030] A kind of soft discoloration real silk fabric and its processing method, concrete steps are as follows:

[0031] (1) Temperature-sensitive color-changing dye solution: based on the mass fraction of 100%, 5% temperature-sensitive dye TPMN3102 royal blue, 3% isocyanate crosslinking agent XC-227, 10% water-based polyurethane emulsion, 0.5% defoamer AFE-3168, and more The volume is deionized water. According to the mass fraction of the dye solution, first dilute 3% of the cross-linking agent XC-227 with the same amount of deionized water, then dilute the 10% water-based polyurethane emulsion with the same amount of deionized water, mix them evenly, and add 0.5% Defoamer AFE-3168, add 68.5% deionized water, add 5% thermosensitive dye TPMN3102 sapphire blue and stir evenly.

[0032] (2) Dyeing: the silk fabric is dyed by the padding method, and the padding dyeing solution, pre-baking, baking, soaping, and drying are processed, wherein the padding dyeing solution and pre-baki...

Abstract

The invention relates to a soft color-changing real silk fabric and a processing method thereof, and belongs to the technical field of real silk fabric dyeing. The processing method comprises the following steps of diluting a water-based cross-linking agent and a water-based emulsion with water, uniformly mixing, adding a defoaming agent, a temperature-sensitive dye and water, and uniformly stirring to obtain a temperature-sensitive color-changing dye solution; dyeing the real silk fabric by adopting a padding method to obtain a color-changing real silk fabric; and carrying out softening finishing on the color-changing real silk fabric by adopting a softening agent solution to obtain the soft color-changing real silk fabric. The method provided by the invention is simple and rapid, does not influence the color change effect of the temperature-sensitive material, enhances the crosslinking fixation degree of the dye and the fiber, improves the utilization rate of the dye in the dyeing process, and reduces the discharge of printing and dyeing wastewater in actual production, and the obtained fabric has high soaping resistance and rubbing resistance color fastness. In addition, the soft color-changing real silk fabric is better in softness and hand feeling, the requirement for attractiveness is met, and meanwhile the requirement for comfort is met.

Description

technical field [0001] The invention relates to the technical field of silk fabric dyeing, in particular to a soft and color-changing silk fabric and a processing method thereof. Background technique [0002] In recent years, with the continuous improvement of living standards, people have higher and higher requirements for the aesthetics, comfort and diversity of clothing. Therefore, the research on functional fabrics has attracted the attention of scientists. They have carried out research on stimuli-responsive materials. A series of studies have been carried out, and the external stimuli include: temperature, light, pH value, ionic strength, enzyme activity, etc. Among these factors, temperature-sensitive materials can be easily applied in the textile field, and at the same time, the change of external temperature is easy to control, so temperature has become a widely used stimulus signal. [0003] Temperature-sensitive materials (commonly known as temperature-changing p...
