多组分羊绒混纺针织纱制备及其性能研究

Preparation and Properties of Multi-Component Cashmere Blended Knitted Yarn

对各系列的多组分低比例羊绒混纺针织纱的强伸性能和捻度进行了测试和分析。结果显示:线密度为20.8tex×2股线、捻度为350 T/m左右的羊绒/羊毛/竹浆纤维三组分混纺纱,线密度为31.3tex×2股线、捻度为350 T/m左右的羊毛/竹浆纤维/PTT纤维三组分混纺纱,以及单纱捻度为650 T/m、股线捻度为400 T/m,线密度为20.8tex×2的羊绒/羊毛/竹浆纤维/PTT纤维四组分混纺纱线性能较好,适合于开发轻薄春秋羊绒衫。

The tensile strength and extension and the breakage and the twist of different series cashmere blended knitted yarns are tested and analyzed. And the results show that the cashmere/wool/bamboo pulp fiber blended yarn with yarn density of 20. 8tex×2, yarn twist about 350T/m, the wool/bamboo pulp fiber/PTT blended yarn with yarn density of 31.3tex×2, yarn twist about 350T/m, the cashmere/wool/ bamboo pulp fiber/PTT blended yarn with yarn density of 20. 8tex×2, single yarn twist about 650T/m, yarn twist about 400T/m, has better performance for developing light and thin cashmere sweater.
