doi:10.19398/j.att.202107037

Abstract

Abstract: To design new thermal protective clothing, this paper designed and weaved six kinds of double stitching fabrics with the same specifications of Nomex^® ⅢA yarns based on plain, 2/2 hopsack, 2/2 twill, and 3/1 twill by changing the fabric texture so as to study the effect of fabric texture on its bending properties, mechanical properties, air permeability, moisture permeability and thermal protective performance. The results show that the bending performance, mechanical properties and thermal protective performance increase while the moisture permeability property decrease with the the tightening of the fabric texture under the same warp and weft density. Among the six kinds of fabrics, the No.1 fabric whose surface texture is plain and inner texture is 2/2 hopsack has the best bending property, mechanical property and thermal protective performance but poor air permeability and moisture permeability. Meanwhile, the thermal protective performance increases by 67.53% compared with that of the fabric system with general flame retardant coatings on the market.

Key words: flame retardant coatings, stitching double fabrics, air permeability, moisture permeability, thermal protective performance

摘要： 为开发新型热防护服,采用相同规格的Nomex^® ⅢA纱线,以平纹、2/2方平、2/2斜纹、3/1斜纹4种组织为基础,改变织物组织结构,设计织造了6种接结双层阻燃面料,研究织物组织对其弯曲性能、力学性能、透气、透湿性能及热防护性能的影响。结果表明:在织物经纬密相同时,织物结构越紧密,其弯曲性能、力学性能和热防护性能增加,透气、透湿性能下降;在6种织物中,表组织为平纹、里组织为2/2方平组织的1#织物的弯曲性能、力学性能和热防护性能最好,透气、透湿性能相对较差,比市售通用的阻燃层所在织物系统的热防护性能提高了67.53%。
