相变调温纤维调温性能试验分析

Experimental Analysis of Phase Change Temperature Regulating Fiber Temperature Regulating Property

分析国产相变调温粘胶纤维的调温性能。采用不同含量调温纤维与涤纶混和,测试纤维混和样的升温和降温曲线;纺制不同混纺比的调温纤维涤纶混纺纱线,采用同一混纺比纱线织制3种组织结构织物,用两浴法染色工艺对调温纤维涤纶混纺织物进行染色处理,分别测试纱线、坯布织物、染色织物的DSC曲线。结果表明:随着调温纤维含量的增加,调温纤维与涤纶混和样、混纺纱线的调温性能提升;织物组织对织物熔融和结晶焓值影响很小,对动态升降温最大温度调控值影响较大;织物染色前后的调温性能差异不大。认为:当调温纤维含量在50%以上时,最高温度调控值超过3℃,满足调温类产品的标准要求;织物厚、透气性好有利于提升调温效果;调温纤维织物适用常规涤纶粘胶混纺织物染整工艺。

Temperature regulating property of domestic phase change temperature regulating viscose fiber was analyzed.The heating and cooling curves of the blended fiber samples were tested by blending polyester with different contents of temperature regulating fiber.Polyester blended yarns with different temperature regulating fiber blending ratios were spun.Three kinds of fabric were made with the same blending ratio yarn.Two bath dyeing process was used to dye the blended fabric.DSC curves of yarn,gray fabric and dyed fabric were tested respectively.The results showed that the temperature regulating property of temperature regulating fiber,polyester blended sample and blended yarn were improved with the increase of temperature regulating fiber content.The fabric weave had little influence on the enthalpy of melting and crystallization,but had great influence on the maximum temperature of dynamic rising and cooling.There was little difference in temperature regulation before and after dyeing.It is considered that the standard requirements of the temperature regulating products can be meet when content of temperature regulating fiber is above 50%,maximum temperature regulating value is above 3℃.Thicker fabric,better air permeability is conducive to improve the temperature regulation effect.Tempering fiber fabric is suitable for dyeing and finishing of conventional polyester viscose blended fabric.
