Abstract
The invention discloses a burn-proof and flame-retardant finishing method for nylon spinning, which comprises the following steps: immersing nylon spinning in a polyamidase solution for modification treatment to obtain modified nylon spinning A; configuring sodium periodate and The solution of the inositol triammonium triphosphate salt of the o-diol hydroxyl group is oxidized to obtain the dialdehyde-based phosphorus-containing flame retardant B; the amino silicone softener is added to the dialdehyde-based phosphorus-containing flame retardant B to obtain a finishing solution , immersing the modified nylon spinning A in the finishing solution for finishing treatment, washing and drying after finishing treatment. The invention adopts polyamidase to modify the surface of nylon fiber, which increases the binding fastness of dialdehyde-based phosphorus-containing flame retardants and fiber and amino silicone softeners, and has long-lasting anti-burning and flame-retardant effects; Anti-burning and flame-retardant finishing under relatively slow conditions can effectively reduce production energy consumption and cost compared with traditional methods. While ensuring a high flame-retardant effect, it can avoid the problems of reduced strength and hand feeling of the fabric.
Description
technical field [0001] The invention relates to the technical field of textile materials, in particular to a burn-proof and flame-retardant finishing method for nylon textiles and flame-retardant nylon textiles. Background technique [0002] Nylon is the most commonly used synthetic fiber raw material and is widely used in sportswear and outdoor textile processing. Compared with natural fibers, nylon fiber products have stronger single fiber strength, excellent wear resistance, not only soft to the touch, but also excellent dimensional stability. In recent years, consumers have put forward requirements for the functionality of clothing (such as cold-proof clothing, jackets) and outdoor equipment (such as tents, travel bags, paragliders) processed with nylon fabrics, that is, the fabrics not only have good appearance and feel, but also It should have excellent protective functions to improve the adaptability of nylon fiber products in different outdoor scenarios. Nylon is t...
