Antistatic flame-retardant composite fabric and preparation method thereof

By introducing antistatic and flame-retardant components stepwise onto the surface of the base fabric layer, and utilizing the synergistic effect of sodium alginate oxide, chitosan, and Ca²⁺, a double-network interpenetrating structure is formed. This solves the problem of mutual interference between antistatic and flame-retardant fabrics during blending in existing technologies, achieves a tight bond between the antistatic layer and the flame-retardant layer, and improves the antistatic, flame-retardant, and durability properties of the fabric.

AI Technical Summary

⚠Technical Problem

Existing antistatic and flame-retardant fabrics are prone to mutual interference and uneven dispersion when conductive and flame-retardant components are blended, which affects the continuity of the conductive network and the stability of flame-retardant properties, making it difficult to maintain good antistatic and flame-retardant properties during repeated washing.

⚗Method used

A step-by-step impregnation process is adopted, in which antistatic components and flame-retardant components are sequentially introduced onto the surface of the base fabric layer. The synergistic effect of sodium alginate oxide, chitosan and Ca²⁺ is utilized to form a covalent and ionic double-network interpenetrating structure, which improves the bonding tightness between the antistatic layer and the flame-retardant layer.

🎯Benefits of technology

It significantly improves the antistatic, flame retardant and durability properties of composite fabrics, and uses environmentally friendly raw materials, meeting the sustainable development requirements of green textiles.

Abstract

The application provides an antistatic flame-retardant composite fabric and a preparation method thereof, and relates to the technical field of composite fabric preparation. The preparation method comprises the following steps: S1, mixing and shearing and dispersing glacial acetic acid, deionized water, chitosan, anhydrous calcium chloride and a carbon nanotube dispersion solution to obtain A tank solution; S2, ultrasonic dispersing a wet-state oxidized sodium alginate filter cake, deionized water and sodium-based montmorillonite to obtain B tank solution; S3, a base fabric layer is immersed in the A tank solution for one time of padding and pre-drying to obtain an antistatic layer; then the antistatic layer is immersed in the B tank solution for two times of padding to obtain a flame-retardant layer; the obtained fabric is subjected to heat baking, washing and drying to obtain the antistatic flame-retardant composite fabric; and the wet-state oxidized sodium alginate filter cake is prepared by mixing deionized water and sodium alginate, stirring and dissolving, adding a sodium periodate solution, heating, stirring and reacting in the dark, adding ethylene glycol, stirring, adding anhydrous ethanol, precipitating, centrifuging and alcohol washing. The composite fabric prepared by the application has good antistatic and flame-retardant properties.
