Embodiment 1

[0023] A preparation method for a flame retardant webbing, comprising the steps of:

[0024] (1) 5wt% lithium chloride ethanol solution is atomized in the ultrasonic atomization box, and the textile fiber is transmitted through the ultrasonic atomization box, the ultrasonic frequency is 60KHz, and the time for the textile fiber to pass through the ultrasonic atomization box is 8min, so that Lithium chloride ethanol solution infiltrates and modifies the surface of textile fibers, and then dries them through a drying chamber. The drying chamber is kept in an inert gas atmosphere for drying. The drying temperature is 100°C. The time is 20s, the inert gas is nitrogen, and the modified fiber is obtained;

[0025] (2) Use electrostatic spraying equipment to electrostatically spray the flame retardant solution on the surface of the modified fiber obtained in step (1). The voltage is 170V, and then the modified fiber enters the dryer for drying to obtain flame-retardant fiber. The dr...

Abstract

The invention relates to the field of braid preparation, and discloses a preparation method of a flame-retardant braid. The preparation method includes the following steps: (1) atomizing a lithium chloride solution in an ultrasonic atomization box, conveying textile fibers to pass through the ultrasonic atomization box thus allowing the lithium chloride solution to infiltrate and modify the surfaces of the textile fibers, and then drying to obtain modified fibers; (2) spraying a flame-retardant solution on the surfaces of the modified fibers obtained in the step (1) through electrostatic spraying, and then drying to obtain flame-retardant fibers; and (3) weaving the flame-retardant fibers into the braid to obtain the flame-retardant braid. The flame-retardant braid prepared by the method, a flame-retardant layer is formed on the surface of the braid and firmly combined with the textile fibers, the steps are simple and convenient, and generation of a large amount of sewage in traditional methods is avoided.

Description

technical field [0001] The invention relates to the field of preparation of webbing, in particular to a method for preparing a flame-retardant webbing. Background technique [0002] With the improvement of people's living standards and the enhancement of fire protection awareness, the requirements for flame retardancy of textile fabrics for home decoration are also getting higher and higher. Flame-retardant textiles can slow the spread of a fire while giving people time to evacuate or take steps to put it out. Therefore, it is particularly important to carry out flame-retardant finishing on textiles in order to prevent the occurrence of fire. [0003] At present, methods such as grafting and copolymerization of flame retardants and fiber molecular chains or methods of impregnating and padding fibers or textile products are mostly used for modification. The former process is more complicated and affects the strength of the fabric, while the latter process Although it is sim...
