芳纶/阻燃粘胶/阻燃锦纶混纺织物制备及其性能

为获得长效阻燃、高强、耐磨且服用性能好的织物，将芳纶1414、阻燃粘胶与阻燃锦纶3种本质阻燃纤维混纺织造，探讨了混纺比、纱线捻度、织物组织结构和黏合剂种类对纱线及其织物力学性能、阻燃性能和色牢度的影响。结果表明：芳纶1414/阻燃粘胶/阻燃锦纶(30/45/25)混纺纱线同时具备优异的力学性能和阻燃性能，阻燃锦纶的加入使三元混纺纱线断裂强度相比芳纶/阻燃粘胶二元混纺纱线提升56%,耐磨次数提升58%,其纱线的力学性能随着捻度增加先增强后降低，峰值捻度为680捻/m;织物采用斜纹组织结构时，其阻燃性能和力学性能优于平纹和缎纹组织；采用非离子型丙烯酸酯共聚物G-BD作为印花浆料黏合剂，可使得到的高强耐磨阻燃织物水洗20次后变色牢度级数仍保持在2级以上。

Preparation and properties of aramid/flame retardant viscose/flame retardant polyamide blended fabrics

In order to obtain fabrics with long-term flame retardancy, which are strong, wear-resistant and with satisfactory wearability, aramid 1414, flame retardant viscose and flame retardant polyamide were blended for producing woven flame retardant fabrics. The influence of fiber blend ratio, strand twist, fabric structure and adhesive types on the mechanical properties, flame retardancy and color fastness of the fabric was discussed. The results show that the aramid 1414/flame retardant viscose/flame retardant polyamide blend ratio 30/45/25 leads to optimal mechanical properties and flame retardancy. Compared with the fabric using aramid/flame retardant viscose blended yarn, the 3-component yarn demonstrates a 56% increase in breaking strength, 58% increase in abrasion resistance. The mechanical properties of the yarn are improved as the twist level increases and peak at 680 twist/m, but decrease with further increase of yarn twist. The flame retardancy and mechanical properties of the fabric with twill weave are better than that of fabrics with plain weave and satin weave. By using non-ionic acrylate copolymer G-BD as binder in printing paste, the color fastness grade of the high-strength, wear-resistant and flame retardant fabric can be kept above grade 2 after washing for 20 times.
