喷气涡流纺纱无PVA浆纱工艺

Study on PVA-Free Sizing Technology of Jet Vortex Spinning

对丙烯酰胺基共聚浆料用于喷气涡流纺纱的无PVA浆纱工艺进行研究。采用丙烯酰胺基共聚浆料对19.7 tex涤/黏喷气涡流纺纱及9.7 tex黏胶喷气涡流纺纱进行浆纱试验,测试丙烯酰胺基共聚浆料的浆膜成膜性能、浆液流动性以及浆纱力学性能。结果表明:丙烯酰胺基共聚浆料的成膜较为柔韧,浆液黏度稳定,流动性较好,对喷气涡流纺纱的上浆效果优异,能够满足无PVA浆纱工艺的要求。

In this paper,the PVA-Free sizing process of acrylamide copolymer used in jet eddy spinning was studied.The sizing experiments of T/R 19.7 tex jet eddy spinning and R 9.7 tex jet eddy spinning were carried out with acrylamide copolymer.The film forming properties,slurry fluidity and sizing mechanical properties of acrylamide copolymer were tested.The test results show that the film forming of acrylamide copolymer slurry is flexible,the slurry viscosity is stable,the slurry fluidity is good,and the sizing efect on jet vortex spinning is excellent,which can meet the requirements of PVA free sizing process.
