Abstract

The invention relates to a method for flame-retardant finishing of silk fabrics by modified nanometer metal hydroxide / zinc salts. Modified nanometer metal hydroxides and zinc salts are used to pad and finish silk fabrics successively to obtain flame-retardant silk fabrics. Wherein, the modified nanometer metal hydroxide is a nanometer metal hydroxide modified by a silane coupling agent. The LOI of the finally prepared flame-retardant silk fabric is ≥ 36.6%, and the damage length of vertical burning is ≤ 6.5 cm; after washing ten times, the LOI of the flame-retardant silk fabric is ≥ 27.3%, and the damage length of vertical burning is ≤ 8.3 cm. The flame-retardant finishing method of the present invention has environmentally-friendly and easy-to-obtain raw materials, is simple and easy to implement, and has excellent promotional value. The flame-retardant real silk fabric finally obtained has both good flame-retardant effect and water-resistant effect.

Description

technical field [0001] The invention belongs to the technical field of textile functional finishing, and relates to a method for flame-retardant finishing of silk fabrics by modifying nanometer metal hydroxide / zinc salt. Background technique [0002] Silk is a protein fiber, known as the "fibre queen". Silk fibroin contains 18 kinds of amino acids that are beneficial to the human body, and the silk feels soft, smooth, thick, plump, and has excellent elasticity. Now it is mainly used in home furnishing, interior decoration and other fields, and high-grade silk products with flame retardant properties are also indispensable. Therefore, the development of silk fabrics with good flame-retardant properties is of great significance to the textile industry. [0003] At present, most of the silk flame retardants used in industrial applications are phosphorus-based cotton flame retardants, such as Pyrovatex CPNEW, which can obtain better flame-retardant effects; Favored by flame re...
