Abstract

The invention provides a single bath finishing technology for antibacterium and dyeing of textile by natural products and relates to textile chemical technology. In the invention, natural products are used as raw materials to produce finishing agent. The raw material is preliminarily crushed by mini plant pulverizer into powder which is then arranged in the waterbath and stirred for some time before going through suction filtration and being produced into natural product finishing agent. The cation-modified cotton fabric is soaked in the finishing agent and treated with dyeing antibacterial finish by the single bath technology. The technology is simple and convenient to operate and energy-saving and environment-friendly. After the finishing, the fabric features good lustre, excellent antibacterial effect, and is nonhazardous to human body.

Description

technical field [0001] The invention discloses a one-bath finishing process for fabric dyeing and antibacterial by utilizing natural products, which belongs to the technical field of textile chemistry. Background technique [0002] Synthetic dyes are widely used for their rich and colorful colors, excellent color fastness and low price. However, as the world advocates health, returning to nature and advocating environmental protection, the disadvantages of synthetic dyes such as harm to the human body and environmental pollution have attracted more and more attention. Good environmental compatibility and biodegradability are becoming a research hotspot in the ecological processing of textiles. [0003] In the process of fabric finishing with natural products, its medicinal active ingredients, aroma ingredients and natural pigments are absorbed by the fabric together. In some cases, the medicinal active ingredients are natural pigment ingredients, so that the dyed fabric has...
