一种超薄轻质面料用抗紫外尼龙6纤维及其制备方法
摘要：
本发明涉及一种超薄轻质面料用抗紫外尼龙6纤维及其制备方法，该纤维由支链尼龙6功能母粒和常规尼龙6切片共混后纺丝而成，其中支链尼龙6功能母粒的质量百分比为6～10%；其制备方法包括：（1）支链尼龙6功能母粒的原位聚合制备或共混制备；（2）将支链尼龙6功能母粒与常规尼龙6切片分别结晶、干燥后混合，然后经真空干燥得共混切片；最后将共混切片经熔融纺丝设备进行共混纺丝即可。本发明减少紫外吸收剂的用量，增加了纤维的可纺性，但是又保证纤维抗紫外以及防紫外老化的效果；本发明的面料在保持了轻质的同时，又能较大吸收紫外线，适用于开发夏天轻薄型用衣。
摘要（英）：

The invention relates to an uvioresistant nylon-6 fiber for an ultrathin and light fabric and a preparation method of the uvioresistant nylon-6 fiber. The uvioresistant nylon-6 fiber is formed by branched-chain nylon-6 functional master batches and conventional nylon-6 chips through blending and spinning, wherein the branched-chain nylon-6 functional master batches account for 6-10% in weight percentage; the preparation method comprises the steps of firstly, preparing the branched-chain nylon-6 functional master batches through in-situ polymerization or blending; secondly, crystallizing and drying the branched-chain nylon-6 functional master batches and the conventional nylon-6 chips respectively and mixing, and then performing vacuum drying to obtain blended chips; and finally, performing melt spinning to the blended chips with melt spinning equipment. The using amount of ultraviolet absorbents is reduced, the fiber spinnability is improved, the uvioresistant and the ultraviolet aging resistant effects are ensured; the fabric can strongly absorbing ultraviolet radiation while light weight is ensured, and is suitable for developing thin and light clothes in summer.
