Embodiment 1

[0015] The quaternary ammonium salt is selected from lauryl trimethyl ammonium chloride, tetradecyl trimethyl ammonium chloride, hexadecyl trimethyl ammonium chloride or octadecyl trimethyl ammonium chloride solution At least one of them, based on the total amount of the modified finishing agent, has a concentration of 0.03 mol / L. The penetrating agent is fatty alcohol polyoxyethylene ether solution JFC, and its mass concentration is 1g / L based on the total amount of modified finishing agent. The pH value of the mixture was adjusted to a neutral range of 6-7. After the modified tussah silk fiber or its fabric treated with the modified finishing agent is dyed with reactive dyes, its dyeing rate, color fixation rate and color fastness are all obviously improved, and the dyeing effect is obviously improved. The amount of quaternary ammonium salt and penetrant used in this example is relatively low, and the cost of modification is relatively low.

Embodiment 2

[0017] The quaternary ammonium salt is selected from lauryl trimethyl ammonium chloride, tetradecyl trimethyl ammonium chloride, hexadecyl trimethyl ammonium chloride or octadecyl trimethyl ammonium chloride solution At least one of them has a concentration of 0.035 mol / L based on the total amount of the modified finishing agent. The penetrating agent is fatty alcohol polyoxyethylene ether solution JFC, and its mass concentration is 2g / L based on the total amount of modified finishing agent. This embodiment is the best modified finishing agent composition, which can make the reactive dye dyeing of the modified tussah silk fiber or its fabric obtain the best dyeing uptake rate, color fixation rate and color fastness.

Embodiment 3

[0019] The quaternary ammonium salt is selected from lauryl trimethyl ammonium chloride, tetradecyl trimethyl ammonium chloride, hexadecyl trimethyl ammonium chloride or octadecyl trimethyl ammonium chloride solution At least one of them, based on the total amount of the modified finishing agent, has a concentration of 0.04mol / L. The penetrating agent is fatty alcohol polyoxyethylene ether solution JFC, and its mass concentration is 5g / L based on the total amount of modified finishing agent. Compared with Example 1, the modification effect of this embodiment is slightly improved, but the improvement is not large. Because the amount of quaternary ammonium salt and penetrating agent is increased, the modification process can be shortened, that is, within the above-mentioned impregnation time range, use a short Time impregnation to achieve the modification effect.

Abstract

The invention provides tussah silk fiber or a fabric cation modified finishing agent thereof and a modified technique thereof, wherein tussah silk fiber or the fabric cation modified finishing agent thereof is formed by mixing quaternary ammonium salt and a penetrant; the quaternary ammonium salt is at least one of solutions of dodecyl trimethyl ammonium chloride, myristyl trimethyl ammonium chloride, hexadecyl trimethyl ammonium chloride or octadearyl dimethyl ammonium chloride; the penetrant is a fatty alcohol-polyoxyethylene ether solution JFC in a nonionic surfactant; and the modified technique comprises the steps of: steeping degummed tussah silk or a fabric of the degummed tussah silk in the modified finishing agent for 20-30 minutes at the modified temperature of 65-75 DEG C, and then carrying out pre-drying and baking for 3 minutes, so as to obtain the modified tussah silk fiber or the fabric of the degummed tussah silk. The technical scheme provides an effective implementation scheme for high-performance and pollution-free dyeing of reactive dyes of the tussah silk fiber or the fabric of the degummed tussah silk.

Description

technical field [0001] The patent application of the present invention relates to the technical field of dyeing technology of tussah silk fiber or its fabric with reactive dyes, and in particular relates to a modified finishing agent and a modification process for tussah silk and its silk fabric for better dyeing effect. Background technique [0002] Tussah silk is a natural protein fiber. Its fabric has the advantages of good elasticity, plumpness and gorgeousness, roughness and comfort, and anti-ultraviolet rays. . [0003] Reactive dyes are water-soluble dyes, which have the technical advantages of complete color spectrum, bright color, good color fastness, simple dyeing process and low cost. And cause dyestuff utilization rate low, dyestuff consumption is big and dyed fabric color fastness is poor. In order to make the floating color formed by reactive dyes that have not chemically reacted with the fabric easily washed out during the boiling and floating process, more ...
