【摘要】 用不同规格的易水解聚酯(EHDPET)/共聚醚酯(COPEET)海岛复合丝与高收缩聚酯长丝、氨纶或普通涤纶长丝组合织制的经平绒织物为基布,对其进行聚氨酯(PU)浸胶、碱减量开纤及磨毛等工艺处理,制得经编超细纤维合成革;研究了不同用纱种类和规格的经编基布与其浸胶开纤织物的性能。结果表明,全牵伸丝(FDY)作经绒的经平绒基布较全部采用牵伸变形丝(DTY)的同组织基布更易与PU胶结合;经绒为FDY、经平为DTY且结构紧密的浸胶开纤织物纵向拉伸延展性大,透气性差;含有高收缩丝和氨纶的经编基布浸胶开纤后,较易形变和回复;所制4种超纤革的透湿率均高于6 000 g/(m~2·d)。更多还原

【Abstract】 The warp-knitted base fabric made of EHDPET/COPEET sea-island composite filament of different specifications, high-shrinkage polyester filament, polyurethane filament and conventional polyester filament are processed into microfiber synthetic leather through impregnating in polyurethane(PU) and alkali peeling. This paper researches the properties of these base fabrics that are knitted in half tricot stitch with different types and specifications of yarns and their impregnated and alkali peeled fabrics. The result indicates that the base fabrics with Fully Drawn Yarn(FDY) are easier to combine with PU adhesive than those with Draw Texturing Yarn(DTY); the compact impregnated and alkali peeled warp-knitted fabrics with FDY and DTY have greater lengthwise extensibility but lower breathability; the impregnated and alkali peeled warp-knitted fabrics with the minority of high shrinkage polyester and polyurethane filaments have higher deformability and recoverability. The water vapor transmission(WVT) of the four kinds of microfiber synthetic leathers exceeds 6 000 g/(m~2·d).更多还原
