Abstract

The invention discloses natural dye for spinning. The dye is prepared from, by weight, 50-70 parts of green alga extraction solution, 30-45 parts of polyacrylic acid compound, 10-15 parts of chitosan, 5-9 parts of chitin, 12-18 parts of styrene-butadiene rubber latex and 16-25 parts of iron oxide red. The invention further discloses a preparation method of the natural dye for spinning. Raw materials of the dye are low in price and easy to obtain, and the dye is natural and healthy and free of toxicity and harms to human bodies; the whole dye is beneficial to coloring, firm in dyeing, not prone to fading, easy and convenient to use, green, environmentally friendly and quite suitable for large-scale industrial production.

Description

Technical field: [0001] The invention relates to the field of textiles, in particular to a natural dyeing agent for textiles and a preparation method thereof. Background technique: [0002] In modern life, environmental pollution is becoming more and more serious, and people's awareness of environmental protection is gradually strengthening. However, the printing and dyeing industry will generate a large amount of sewage, and if it is discharged randomly, it will cause serious pollution to the environment. Compound dyes will not only have adverse effects on the environment, but also cause safety hazards to human health. Compound dyes are likely to cause skin allergies, and some even have carcinogenicity. Therefore, there is an urgent need to study some natural dyes, which will not harm human health while protecting the environment. [0003] Chinese patent CN201510252220.8 discloses a dyeing agent for natural plant textile fabrics. The dyeing agent uses impatiens flower extr...
