Description
Technical Field
The invention relates to the technical field of real silk fabric dyeing, in particular to a color-changing real silk fabric and a processing method thereof
Background
In recent years, with the improvement of living standard, people have higher and higher requirements on the beauty, comfort and diversity of clothes, so that research on functional fabrics attracts the attention of scientists, and the scientists have carried out a series of researches on stimulus response type materials, and the external stimulus factors are as follows: temperature, light, pH, ionic strength, enzyme activity, and the like. Among these factors, the temperature sensitive material can be conveniently applied to the textile field, and at the same time, the change of the external temperature is easily controlled, so that the temperature becomes a widely used stimulus signal.
The temperature sensitive material (commonly called temperature change powder) mainly comprises three parts of color changing dye, color developing agent and solvent. Under the high temperature state, the color-changing dye and the color developing agent are dissolved and dispersed in the solvent, and the system is in a white state. When the temperature is reduced, the solvent is gradually solidified, the color-changing dye and the color-developing agent are close to each other, and the color-changing dye is subjected to structural change under the action of the color-developing agent, so that the system can show color. By regulating and controlling the solidification temperature of the solvent, temperature-change products which change color at different temperatures can be prepared.
The oxazoline compound can be chemically reacted with macromolecules containing carboxylic acid, acid anhydride, epoxy group, phenolic group, sulfydryl, halogen and other groups, so that the oxazoline compound can be used as a coupling agent, a chain extender, a curing agent, a cross-linking agent and a heat stabilizer, thereby obviously improving the thermal stability, hydrolysis resistance and the like of the polymer. The oxazoline ring in the cross-linking agent can react with related groups in real silk fabrics and temperature-sensitive materials, so that the adhesive force of the dye is improved, the cross-linking fixation degree of the dye and fibers is enhanced, and the soaping and rubbing color fastness after dyeing is high.
However, the existing color-changing real silk fabric has poor hand feeling and low dye crosslinking and fixation degree, so that the color-changing effect of the real silk fabric is poor, the utilization rate of the dye in the dyeing process is low, the color fastness of soaping and friction after dyeing is poor, the discharge of printing and dyeing wastewater in actual production is increased, and the cost of the color-changing real silk fabric is increased.

(1) temperature-sensitive color-changing dye liquor: by mass fraction of 100%, the temperature sensitive dye TPMN3102 sapphire blue is 5%, the oxazoline cross-linking agent WS-500 is 3%, the defoaming agent AFE-3168 is 0.5%, and the balance is deionized water.

Table 1 shows the finally measured fastness test results of the discolored real silk fabric:
TABLE 1 fastness test results of fabrics
As can be seen from Table 1, when comparing example 1 with comparative examples 1 and 2, the soaping resistance and rubbing resistance of the color-changing silk fabric prepared in example 1 are obviously better than those of comparative examples 1 and 2, because the temperature-sensitive color-changing dye solutions of comparative examples 1 and 2 do not contain oxazoline cross-linking agent WS-500 and aqueous polyurethane emulsion at the same time, and cannot play a role in fixing color, so that the color fastness and the washing resistance of the fabric are poor.
The results show that the color-changing real silk fabric finished by the method has good soaping resistance, friction resistance and color fastness.
It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments.
