AI Technical Summary

Problems solved by technology

The flame retardant fiber made by the coating method, because the flame retardant is coated on the fiber surface, makes the fiber surface hard and rough, and even some flame retardants will emit some unpleasant smells, and the flame retardancy will decrease after long-term use, making the fiber The application field is limited; the flame-retardant fiber prepared by the blending method has a fundamental change in the surface state and softness of the fiber compared with the coated fiber, but the flame-retardant fiber prepared by this method still has a single function, Shortcomings such as narrow application fields have seriously restricted the market promotion of flame-retardant fibers
[0004] Bamboo pulp has defects such as poor reactivity and high gray iron content. If bamboo pulp is used to produce bamboo pulp flame-retardant fibers, the fiber preparation process is more difficult than other pulp fibers, and at the same time, the fiber indicators are also different from other pulp fibers. reduce
The use of bamboo pulp to produce bamboo pulp flame-retardant fiber has not been reported in domestic publications and patents

Abstract

The invention relates to a bamboo pulp flame-retardant fiber produced by using phosphorus flame retardant as functional material and a preparation method thereof. The prepared bamboo pulp flame-retardant fiber comprises the following components in percent by weight: 84.7-92.85% of bone dry fiber, 7-15% of water and 0.15-0.30% of oil solution. The fiber bacteriostatic value is greater than or equal to 2.0, the sterilizing value is greater than or equal to 0.3, and the limited oxygen index of the fiber fabric reaches more than 26%. The bamboo pulp flame-retardant fiber can not generate toxic gas or harmful gas after being burnt and can be widely applied to the fields of home textiles, decoration and the like. The invention creates a new field for the functionalization of the bamboo pulp fiber.

Description

technical field [0001] The present invention relates to bamboo pulp flame retardant fiber produced by using phosphorus flame retardant as additive and its preparation method. Flame retardant fibers. Background technique [0002] Bamboo pulp fiber is made of bamboo as raw material, processed into bamboo pulp, and then processed by viscose fiber production process. Bamboo pulp fiber not only has the characteristics of viscose fiber, but also has excellent antibacterial and antibacterial functions, making bamboo pulp fiber a textile material with excellent performance. However, with the increasing consumption of various textiles, fires caused by textiles are also increasing. Developed countries such as Europe, America and Japan have put forward requirements on the flame retardancy of textiles and formulated various standards to restrict non-flame retardant fabrics from the types of textiles and applicable occasions, which will affect the application and export of bamboo fiber...
