Embodiment 1

[0045] The preparation method of the waterproof coil base cloth described in the present embodiment comprises the following steps:

[0046] S101. Put virgin polyester fiber 2.78dtex*65mm and low melting point polyester fiber 2.22dtex*51mm into the first feeding bin and the second feeding bin respectively, and according to the mass ratio of raw polyester fiber to low melting point polyester fiber is 3 :7 set the feeding ratio of the first feeding bin and the second feeding bin;

[0047] S102. Feed the virgin polyester fiber and low-melting point polyester fiber into the cotton mixing box through the feeding bin, and further mix the fibers; then send the fibers into the fine opening device, fully break the fibers into single fibers, and then pass the fibers through Pipeline transportation to the next process;

[0048] S103. the fully opened fiber is sent into carding machine, carded into a web, and the fiber web is obtained. The chest cylinder speed of the carding machine is 50...

Abstract

The invention provides waterproof roll base cloth, a PVC waterproof roll and a preparation method of the PVC waterproof roll. The waterproof roll base cloth is prepared from mixed fibers of native polyester fibers and low-melting-point polyester fibers, and the mass ratio of the native polyester fibers to the low-melting-point polyester fibers in the mixed fibers is 3: (5-9). The waterproof roll base cloth is prepared by mixing the native polyester fibers and the low-melting-point polyester fibers and adopting an improved production process, and the problems of unstable breadth, thermal shrinkage during construction and the like in a production process of the waterproof roll base cloth can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of nonwoven fabric production, and in particular relates to a base cloth of a waterproof coiled material, a PVC waterproof coiled material and a preparation method thereof. Background technique [0002] PVC (polyvinyl chloride) waterproof roll is a new type of polymer waterproof roll extruded from polyvinyl chloride resin as raw material, adding plasticizers, fillers, antioxidants, ultraviolet absorbers and other additives. PVC waterproof membrane has the advantages of good elasticity, high elongation, small shrinkage, good low temperature toughness, and convenient construction, and has been used in many fields. The skeleton of the PVC waterproof membrane is the waterproof membrane base fabric, which makes the PVC waterproof membrane have a certain shape, strength and toughness, so the strength and toughness of the waterproof membrane base fabric can directly affect the PVC waterproof membrane. [0003] At ...
