Non-directional door curtain tape for industrial use and manufacturing method thereof

Abstract

The invention discloses an industrial non-directional curtain belt and a manufacturing method of the industrial non-directional curtain belt, which relate to a light conveyor belt for a rapid roller shutter door and a manufacturing method of the light conveyor belt for a rapid roller shutter door. The industrial non-directional curtain belt is mainly applied to industrial rapid roller shutter doors and can be applied to ultra-wide roller shutter doors. The industrial non-directional curtain belt uses a polyester fabric as a basic fabric, and a structure of a PVC (polyvinyl chloride) adhesive layer adhered between two basic fabrics is adopted. The basic fabric is a non-lateral stable polyester fabric which does not contain monofilaments and whose fabric count is 4030. Ultralow shrinkage polyester multifilament with the warp-wise and weft-wise finenesses which are both 1000D is twisted at the speed of 60 turns per meter. The industrial non-directional curtain belt provided by the invention provides the ultra-wide curtain belt for the industry of rapid roller shutter doors and the curtain belt can be cut vertically according to the width of the roller shutter doors so as to meet the requirement of width. In addition, the industrial non-directional curtain belt provided by the invention can be used bidirectionally to avoid the width splicing step of the original roller shutter door, thereby lowering the business cost and reducing the yield of unaccepted products.

Description

technical field [0001] The invention relates to an industrial non-directional door curtain belt and a manufacturing method thereof, which relate to a light conveyor belt for a fast rolling door and a manufacturing method thereof, and is mainly applied to an industrial fast rolling door, and can be applied to a non-directional door curtain belt on an ultra-wide rolling door . Background technique [0002] The fast rolling door has many functions such as heat preservation, cold preservation, insect prevention, windproof, dustproof, sound insulation, fire prevention, odor prevention, lighting, etc., and is widely used in food, chemical, textile, electronics, supermarket, refrigeration, logistics, storage, etc. It can meet the needs of high-performance logistics and clean places, save energy, automatically shut down at high speed, improve operating efficiency, and create a better operating environment. With the use of large rolling doors, the requirements for the door curtain b...

AI Technical Summary

Problems solved by technology

The traditional door curtain belt is made of laterally stable polyester fabric, so the lateral and longitudinal properties are quite different, and it cannot be used in different directions. Therefore, it is difficult to meet the needs of current customers due to the limitation of the width of the processing equipment.

[0003] According to the customer's requirements for the width of the door curtain, at present, the production enterprises mainly adopt the following two solutions: 1) Improve the equipment and invest in a wide production line. The disadvantage is that the investment in equipment is too large, and it cannot meet different widths. Customer needs; 2) During the post-finishing period, the width of the curtain belt can be adjusted. Although the existing equipment can be used to avoid a large amount of capital investment, the width of the width is affected by the worker's operating technology and various factors in the process of processing the curtain belt. The wide door curtain belt is not smooth, and there are waves in the widening part, which will affect the appearance and performance of the door curtain belt
