兔羊毛加工新助剂——和毛油

兔毛或兔、羊毛混纺制品质地轻,手感滑糯,保暖性好,受到人们的青睐。但在纺织和穿着过程中容易掉毛,这已成为一个突出和急待解决的问题。最近,杭州市化工研究所研制成功的毛纺工业前纺用和毛油油剂HA-1就是用以减少飞毛、落毛,提高兔羊毛质量的新助剂。由于兔毛纤维光滑,摩擦、抱和力小,强力低等原因引起纤维掉毛。在纤维上机梳理纺纱前,以雾化喷淋方式将含有和毛油新助剂的水乳化液均匀地洒到纤维表面上,改善了纤维加工性能,使毛纤维易开松,具有理想的可纺性。

Study on the Prevention of Rabbit Hair from Loss

A new method is presented to solve the problem of loss of rabbit hair by using ES fiber blending with rabbit hair. ES fiber is used to bond the rabbit hair to prevent the rabbit hair from losing after heat setting. The factors affecting hair loss are heat setting temperature, rabbit hair/ES fiber blend ratio, fabric heating setting, twists of yarn, etc. Temperature of heat setting and ES fiber content are the two key factors. This method has almost no detrimental effect on the coziness of the fabric, which is better than other hair loss prevention methods.

Study of Rotor Spun Basofil/Cotton Blended Yarn Quality Characteristics during Optimisation of Processing Parameters

Yarn quality characteristics are affected by processing parameters. A 36 tex rotor spun yarn of 50/50 Basofil/ cotton （B/C） blended yarn was spun, and the spinning process optimised for rotor speed, opening roller speed and twist factor. Selected yarn characteristics were studied during the optimization process. During the optimizations process yarn elongation and hairiness reduced with increase in rotor speed. Tenacity increased with increase of rotor speed. The increase in TF caused tenacity and CV of count to increase up to a peak and then started to decrease with further increase of TF.While TF caused an increase in yarn hairiness, elongation decreased to a minimum level and then started to increase with further increase of TF. CV of count and hairiness increased with increase in opening roller speed, but tenacity and elongation decreased with increase in opening roller speed. The optimization process yielded the optimum levels for rotor speed, opening roller speed and twist factor （TF） as 45,000 rpm, 6,500 rpm and 450 respectively. As per uster Standards the optimum yam showed good results for CV of count, CV of tenacity and thin places/km.
