种废旧纤维制品制备再生高强度短纤维的工艺，1)将废旧聚酯纤维制品上的纽扣、拉链处理掉，送入恒温恒湿的环境下保存；2)将废旧聚酯纤维制品采用智能颜色成分分拣系统进行分色，把统种颜色的分拣为类；并对同种颜色中的废旧聚酯纤维制品进行成分含量分拣；3)将同种颜色的废旧聚酯纤维制品送入超声清洗设备清洗，然后置于低温冷风干燥设备；4)将干燥后的废旧聚酯纤维制品破碎成块状，进行消毒处理；5)将消毒后的废旧聚酯纤维制品送入挤出机进行过滤挤出，使PET熔体从模头挤出去，而棉纤维则被过滤掉；6)将挤出的PET熔体送入增粘设备中，加入增粘剂，调整熔体的粘度；7)将增粘后的PET熔体直接用于纺丝，即可得到高强度短纤维。 A technology for preparing regeneration high-strength short fibers through waste fiber products comprises the steps that firstly, buttons and zippers on the waste polyester fiber products are put away and fed into a constant-temperature constant-humidity environment to be stored; secondly, an intelligent color component sorting system is adopted for the waste polyester fiber products to carry out color sorting, waste polyester fiber products of the same color are sorted into the same kind, and the waste polyester fiber products in the same color are subject to component content sorting; thirdly, the waste polyester fiber products of the same color are fed into an ultrasonic cleaning device to be cleaned, and then
