A kind of high-strength polyethylene light conveyor belt and its preparation method
A technology of high-strength polyethylene and light-duty conveyor belts, which is applied in conveyors, chemical instruments and methods, clothing belts, etc., can solve the problems of long-distance transportation that cannot meet the needs of customers, the extension of the polyethylene conveyor belt, and the tensile strength and tension. The strength does not meet the requirements, the polyester staple fiber has low strength, etc., and achieves the effect of reducing the increase in fabric cost, reducing the tension length requirement, and improving the flow performance

Embodiment 1
[0029] see figure 1 Be the process flow chart and the figure 2 Shown in the structural representation of the high-strength polyethylene light-duty conveyor belt of the present invention, the manufacturing method of the high-strength polyethylene light-duty conveyor belt comprises the following steps:
[0030] S1: Preparation of high-strength composite yarn fabric: composite yarn of polyester filament and polyester staple fiber is used in the warp direction, the linear density of polyester filament is 800D low-shrinkage polyester activated yarn, polyester staple fiber is 10S / 3 short yarn, weft 21S / 6 short yarns are used in the direction, the warp density of the fabric is 40 threads / inch, the weft density of the fabric is 15 threads / inch, and the weaving method adopts plain weave structure. The high-strength composite yarn fabric is shaped under infrared heating conditions;
[0031] S2: Prime the composite yarn fabric after setting with high melt index polyethylene powder (th...
