用尼龙短纤维和聚丙烯颗粒制取复合网络丝的方法和装置
摘要：
一种用尼龙短纤维和聚丙烯颗粒制取复合网络丝的方法和装置，其步骤是：把长度为1-5mm的尼龙短纤维，在压力为0.45-0.6Mpa的高压气流作用下，进行开松和打散得到单纤维状态的尼龙纤维。把单纤维状态的尼龙纤维和聚丙烯颗粒按照重量比为1：95-100，通过搅拌的方式进行混合均匀，在温度为165-175℃中进行熔融得到混合熔融物。把混合熔融物在压力为30-40Mpa，通过拉丝方式，并在温度为20-30℃中进行冷凝，得到复合网络丝；通过单纤维状态的尼龙纤维与聚丙烯颗粒作用，克服了聚丙烯的技术缺陷，因此提高了复合网络丝的耐疲劳强度。
摘要（英）：

Provided are a method and a device for preparing a composited interlaced yarn from a nylon short staple and polypropylene granules. The method comprises the steps of opening and scattering the nylon short staple about 1-5mm long under the action of the high pressure draft at the pressure of 0.45-0.6Mpa to obtain a nylon fiber in a single fiber state. The nylon fiber in the single fiber state and the polypropylene granules are stirred at the weight ratio of 1:(95-100) to be mixed uniformly, and are then melted at the temperature of 165-175 DEG C to obtain a mixed melt. The mixed melt is condensed through a wire-drawing mode at the pressure of 30-40Mpa and the temperature of 20-30 DEG C to obtain the composite interlaced yarn; the technical defect of the polypropylene is overcome because of the actions of the nylon fiber in the single fiber state and the polypropylene granules, therefore, the fatigue resistance of the composite interlaced yarn is improved.
