Abstract

The invention discloses silk-gum and organic-acid finishing liquid and a method thereof for skin-close finishing on a cotton fabric, and relates to the technical field of spinning and weaving. Deguming is carried out on natural silk by using an organic acid such as citric acid, butanetetracarboxylic acid and the like, so as to obtain organic acid degummed liquid; the obtained degummed liquid is directly used for the crease-resistant finishing of a textile without needing treatment. The cross-linking reaction among the organic acid, the cotton fabric and silk gum is catalyzed through adding a composite catalyst sodium ethylene diamine tetracetate and nano TiO2; the use level of the catalyst is drastically reduced; the environmental pollution is greatly decreased; the cost is low. The cotton fabric is jointly finished through the organic acid and sericin; not only can the key problem that the crease-resistant and shrinkage-prevention performance of the cotton fabric is poor be solved, but also the proteinic skin-close attribute is given to the cotton fabric at the same time.

Description

technical field [0001] The invention relates to the textile field, in particular to a sericin organic acid finishing solution and a skin-friendly finishing method for cotton fabrics. Background technique [0002] Cotton fabric has the advantages of softness, breathability, and moisture absorption, and is widely used in clothing fabrics, decorative fabrics, and industrial fabrics. However, when the cotton fabric is subjected to external forces during washing or wearing, the cellulose molecules are deformed along the direction of the external force, the basic structural units are relatively slipped, and the hydroxyl groups will generate and re-establish new hydrogen in new positions. key, this irreversible deformation causes a large number of wrinkles in the cotton fabric. In order to improve the wrinkle-prone properties of cotton fabrics, the anti-wrinkle finishing of cotton fabrics is often carried out by cross-linking method. . [0003] In the prior art, cotton fabrics a...
