Abstract

The invention discloses a coloring agent for textile fabric. The coloring agent for the textile fabric is prepared from the following components: polypropylene glycol, aloe extracting solution, dibutyltin dilaurate, alum, hydroxypropyl methyl cellulose, polyvinylpyrrolidone, acetic ether and blocked polyisocyanate, wherein the aloe extracting solution is prepared by using the following preparationmethod: firstly loading aloe leaf dry powder in a supercritical extraction kettle, feeding carbon dioxide, performing extraction separation by using supercritical carbon dioxide, wherein an extraction temperature is 35-50 DEG C, an extraction pressure is 8-25 MPa, extraction time is 1-3 hours, a flow rate of the carbon dioxide is 1-10 L/h, and a flow rate of an entrainer is 1-5 ml/min; and decompressing the supercritical carbon dioxide containing an extract, separating an extraction product, wherein a separating temperature is 25-50 DEG C, and a separating pressure is 2-10 MPa, and collectingthe obtained extraction product, namely the aloe extracting solution. The coloring agent is good in colorability, difficult to color fading, bright in color and lustre, and harmless to a human body.

Description

technical field [0001] The invention relates to the technical field of textile fabrics, in particular to a dyeing agent for textile fabrics. Background technique [0002] At present, a large amount of chemical dyes are used in the dyeing process of textile fabrics. The finished dyes are easy to fall off during use, causing skin allergies to the wearer, and even carcinogenic, which has a serious impact on the human body. Moreover, these chemical dyes produce a large amount of sewage in the synthesis process, such as direct discharge, polluting the environment, such as discharge after treatment, and the treatment cost is relatively expensive. The existing natural dyes are not suitable for large-scale industrial production due to the cumbersome preparation process and high cost. [0003] In response to the above phenomenon, patent CN 106087474 A discloses a dyeing agent for textile fabrics, which is made of the following raw materials in parts by weight: 40-60 parts of plant e...
