棉/丝光羊毛/Outlast纤维混纺纱的性能

Properties of cotton/mercerized wool/Outlast fiber blended yarns

为研究Outlast纤维含量对棉/丝光羊毛/Outlast混纺纱热性能的影响,采用差示扫描量热仪对其进行测试分析。结果表明,Outlast纤维的含量对相变调温的起止温度、峰值温度影响较小。在降温过程中终止温度和峰值温度随Outlast纤维含量的增加逐渐降低。混纺纱降温时的相变热焓值与Outlast纤维含量之间呈显著线性关系,升温时混纺纱的相变热焓值与Outlast纤维含量的线性关系没有降温时显著。在Outlast纤维含量为40%时,混纺纱的热焓值和相变起止点的温度都相对较好。

In order to study the cotton /mercerized wool /Outlast fiber blended yarns′ thermal properties,DSC was used to test the thermal properties of the blended yarn by varying Outlast fiber content.The results showed that the effect of Outlast fiber content on the beginning,ending,and peak temperatures of the phase-changing temperature-regulating is very small,only in the cooling process the ending and peak temperatures slightly decrease with the Outlast fiber content increases.Furthermore,there is a linear relationship between the yarns′ enthalpy values and the Outlast fiber content at the time of cooling,but it is not so prominent during the warming process.When Outlast fiber content is 40%,yarn′s enthalpy value and the starting and ending points of phase-changing are relatively good.
