Problems solved by technology

[0005] At present, the technology of extracting active ingredients from natural products is relatively mature. In the research on the application of natural extracts in the functional finishing of textiles, the main focus is on the single-purpose research, that is, the use of a certain extract in the dyeing of textiles , or use a certain extract for antibacterial finishing, or use a certain extract for anti-ultraviolet finishing. Effects, especially the use of optimal process conditions, the one-bath multifunctional finishing of textiles, that is, the research on simultaneously obtaining dyeing, antibacterial and anti-ultraviolet effects has not been reported.

Embodiment 1

[0017] The composition of natural extracts used in this example includes (based on solid mass): 10 parts of Scutellaria baicalensis extract, 5 parts of Coptidis Rhizoma extract, 2 parts of gallnut extract, and 8 parts of lac extract. In actual use, natural extracts include shellac extract, and two or more of the extracts of Coptidis Rhizoma, Scutellaria, Pomegranate Peel, Houttuynia cordata, and Honeysuckle; One or more of them; the selection of components and proportions of each natural extract can be determined according to the product color and the index requirements of anti-ultraviolet and antibacterial functions. The above-mentioned natural extracts are active ingredients extracted from their plants or other natural products. The extraction method is the prior art. For example, the extracts of Scutellaria baicalensis and Coptis chinensis can be extracted at 100°C with water as the solvent, and the concentrate after vacuum distillation The extract method of Galla gall is t...

Embodiment 2

[0022] The composition of the natural extract used in this example includes (by solid mass): 6 parts of pomegranate peel extract, 5 parts of Scutellaria baicalensis extract, 6 parts of honeysuckle extract, 8 parts of turmeric extract, and 5 parts of shellac extract. The following extraction methods can be used to extract active ingredients from the above natural products: the extracts of pomegranate peel, scutellaria baicalensis and honeysuckle are extracted at 100°C with water as a solvent, and the concentrates are distilled under reduced pressure; the extracts of turmeric are extracted with 60% The ethanol solution is refluxed and extracted in a Soxhlet extractor, and the concentrate is distilled under reduced pressure; the shellac extract is extracted with a dilute sodium carbonate aqueous solution, neutralized and concentrated.

[0023] The treatment process of natural extracts on silk fabrics is as follows: the amount of extracts is 15% (o.w.f.), the bath ratio is 1:40, th...

Abstract

The invention discloses a method for real silk fabric functional finishing, especially relates to a method for one-bath multifunctional finishing of real silk fabric by utilizing natural extract, which pertains to textile dyeing and finishing technical field. The invention includes the following steps: placing real silk fabric in solution with 5-20%(o.w.f) natural extract, liquor ratio of 1:10 to 1:100 and PH value of 2-8, treating for 10-100min; then treating for 10-100min in solution with 3-15%(o.w.f.) metal salt, liquor ratio of 1:10 to 1:100 and PH value of 4-8; after washing, dehydrating and furnace drying, completing one-bath finishing with dyeing, antimicrobial and anti-ultraviolet function to real silk fabric. The invention reduces manufacturing procedure of real silk fabric, has effect of energy-saving and emission-reduction, improves cleaning production of textile processing, is harmless to human body and surroundings, and conforms to ecological textile processing requests.

Description

technical field [0001] The invention relates to a method for functional finishing of real silk fabrics, in particular to a method for one-bath multifunctional finishing of real silk fabrics using natural extracts, which belongs to the technical field of textile dyeing and finishing. Background technique [0002] In recent years, with the improvement of people's living standards and the development of science and technology, people pay more and more attention to environmental protection and human health. In the process of textile processing, the raw materials and production technology of textile processing are required to have the least damage to the ecology all over the world. Since the German Legislative Assembly in July 1994 banned the use of azo dyes or other dyes for carcinogenic effects on textiles, synthetic dyes and auxiliaries or their raw materials have been found to be harmful to the environment and humans. It is restricted to be used in the processing of textiles...
