Problems solved by technology

At present, flame retardant coating is often used to impart flame retardant properties to silk fabrics. This method is very effective in the early stage, but when the fabric is washed with water or organic solvents, the flame retardant function will be destroyed.

Abstract

The invention discloses an oil-proof flame-retardant real silk textile and a finishing technology thereof. According to the technology, by conducting modification treatment on the real silk textile, functions of oil proofing and flame retarding are given to the real silk textile. Compared with the prior art, the oil-proof flame-retardant textile and the finishing technology thereof have the following advantages that the real silk textile finished through the technology cannot be infiltrated by oil drops, and the oil drops can be easily removed, so that the real silk textile has an obvious oilresistance function; the surface of the real silk textile is stable and lasting in flame retardant performance, and after long-term or multiple times of washing, a limit oxygen index does not decrease.

Description

technical field [0001] The invention belongs to the technical field of textiles, and relates to the modification of a real silk fabric, in particular to an oil-proof and flame-retardant real silk fabric and a finishing process thereof. Background technique [0002] Silk fiber is a kind of protein fiber. Protein fiber is an organic nitrogen-containing polymer with high molecular weight and complex structure, but its constituent elements are not many. Generally, protein contains 50-55% carbon, 6-7% hydrogen, and 20-20% oxygen. 30%, nitrogen 12-19% and a small amount of sulfur and trace metal elements. Due to its high nitrogen content, sulfur content, low hydrogen content, and high moisture regain under standard conditions, compared with other fibers, protein fiber has certain flame retardant properties. For example, the limiting oxygen index of real silk fabrics is about 23%, but this still cannot meet the current increasingly stringent flame-retardant requirements for cert...
