Problems solved by technology

In the prior art, such as JP8-260361A, for the dyeing of protein-finished non-protein fiber textiles, the method used is to coat the silk protein on the textiles, and then contact the textiles with dyes for dyeing, but this method is easy to cause color difference , color flower and protein denaturation and other phenomena
Therefore, it is difficult to choose suitable dyes or dyeing process conditions for protein-finished non-protein fiber textiles

Embodiment Construction

[0017] First weigh the micron silk protein powder obtained by physical preparation and dissolve it in water, and pour it into the dyeing bath with a bath ratio of 1:20 with the silk protein powder, add leveling agent and add 0, and then Add 20-60 g / L Yuanming powder, start from 30°C, heat up to 85-95°C, vibrate and dye for 1.5 hours, dehydrate with a centrifuge after cooling, and make colored silk protein powder.

[0018] Weigh the prepared colored silk protein powder, dispersant such as T-60 and non-ionic surfactant as emulsifier, mix according to the ratio of 100:2~3:1.5~2, stir with high speed mixer for 3~5 minutes , to produce a stable silk protein slurry. Then take 2 to 8 parts of silk protein slurry, add 1 to 5 parts of acrylic emulsion copolymer as a fixing agent, stir evenly with a stirrer, and then add silk protein powder at a ratio of 1:2 to 3 for thickening paste The acrylic synthetic copolymer is stirred with a stirrer for 5 minutes to obtain a stable silk protein...

Abstract

The related preparation method comprises: preparing micron-level silk albumen powder by physical way; dyeing the powder; adding dispersant, emulsifier fixing agent and thickener to obtain the stable target fit to sort and dye technique for non-protein fiber textile. This invention needs not traditional dye paste to reduce pollution with simple technique.

Description

technical field [0001] The invention relates to a preparation method of a silk protein colorant, and the colorant is especially suitable for simultaneous processing technology of coloring of non-protein fiber textiles and protein finishing. Background technique [0002] Natural silk, because its structure is very similar to human skin, enjoys the reputation of "second skin" and is the essence of beauty bestowed by nature on human beings. Clothes and silk floss products processed from natural silk have good ventilation and warmth retention properties, and are light and comfortable. Silk protein is rich in 18 kinds of amino acids necessary for the human body. It has a good preventive effect on skin care and prevention of various skin diseases caused by moisture or dryness. It is an excellent natural nutrient. With its special crystalline structure, silk protein can reflect part of ultraviolet rays and absorb part of infrared rays, so it has sun protection effect. [0003] Th...
