氨基胍盐酸盐抗菌改性生物基PA56纤维的制备与性能

Preparation of bio-based PA56 fiber modified with aminguanidine hydrochloride and its properties

通过制备氨基胍盐酸盐抗菌改性生物基PA56母粒,再在PA56熔融纺丝的切片中共混不同质量比例的母粒制得纯PA56纤维、0.5wt%氨基胍盐酸盐的抗菌改性PA56纤维和1.0wt%氨基胍盐酸盐的抗菌改性PA56纤维,并试织成相同规格的织物。在相同的测试条件和测试标准下,对纺制的纤维和试织的织物进行拉伸断裂强力、断裂伸长率、线密度、紫外线防护性能和抗菌性等对比测试。测试结果表明,PA56纤维共混氨基胍盐酸盐材料后,纤维的力学性能随着混纺比例的增加而降低,纤维的线密度和织物紫外线防护性能变化不大,但织物的抗菌性能随着共混比例的增加显著提升。

Three type bio-based PA56 fibers of pure PA56 fiber,antibacterial modified PA56 fiber with 0.5wt%aminoguanidine hydrochloride,and antibacterial modified PA56 fiber with 1.Owt%aminoguanidine hydrochloride are made by melting spinning method with different contents of powder of aminoguanidine hydrochloride,and then woven into 3 fabrics with same weave structure and specifications.The fabric properties of breaking tenacity,elongation,linear density and CV values,anti-UV and anti-bacteria are tested under same testing condition and standards.The test results show that the mechanical properties of PA56 fiber blended with aminoguanidine hydrochloride material decrease with the increase of blending ratio.The linear density of the fiber and the UV protection performance of the fabric do not change much,but the antibacterial performance of the fabric significantly improves with the increase of blending ratio.
