A kind of production equipment and process of pvc tubular membrane yarn

Abstract

The invention belongs to the technical field of PVC plastic woven fabrics, and in particular relates to a production equipment for PVC tubular membrane filaments, comprising a compressed gas steady flow system, a tubular mould, a cooling device and a wire collecting device, wherein the tubular mould comprises a vertical The mold core and the mold cover are provided, the axis of the mold core is provided with a through air guide channel, and the air guide channel is connected with the steady flow gas pipe to form a gas steady flow system. In the water tank, a horizontal water tank is arranged on one side of the vertical water tank, a wire guide wheel is arranged in both the vertical water tank and the horizontal water tank, and the horizontal water tank is connected to a wire collecting device through a tractor. The invention also discloses a process for producing PVC tubular film yarn by using the above-mentioned equipment. The production equipment and process of the PVC tubular film yarn provided by the invention have similar appearance to that of the calendered film yarn, are rough and restrained, and can be quickly put into production in small batches and multiple varieties.

Description

technical field [0001] The invention belongs to the technical field of PVC plastic textiles, and in particular relates to a production equipment and process of PVC tubular membrane yarn. Background technique [0002] The warp and weft yarns used in the existing PVC plastic textile fabrics, one is to use PET / PVC coated yarns, the process is to use high-strength industrial polyester yarns as the skeleton (core yarn), and the PVC is extruded and melted into streams on the outside. The surface of the polyester filament is coated dynamically and uniformly in a circular shape, and the polyester filament can be either covered or monofilament. [0003] The second is to use the film silk process to make the warp thread, and the weft thread is to cover the thread. The film thread process is to cut the PVC calendered film into film strips of a certain width (generally 1cm), and then unwind and warp and weave it into PVC plastic textiles. things. [0004] The main flaws are: [0005]...

AI Technical Summary

Problems solved by technology

[0005] 1. The appearance of PET / PVC coated wire is relatively regular, and the resulting fabric style is relatively clean. When it is applied to carpets, in order to reflect the rough and atmospheric design concept, it needs thicker and wider tows to weave. If the covering yarn is too thick, the first one is difficult to weave, and the appearance of the two is old-fashioned.

[0006] 2. Although the second type of film yarn currently used meets the requirements of appearance style, due to the large production batch and long production cycle of calendered film, it cannot meet the requirements of diversified design color requirements and limited delivery time, so it is often decorated The project is coming to an end, the membrane materials have not yet been produced, and cannot adapt to the market, so a large amount of storage must be prepared, the backlog of funds, and the production cost are also high

[0007] 3. There are also defects in the current yarn collection equipment. When collecting yarn, the membrane yarn is directly put into the barrel. This method is likely to cause irregular and concentrated stacking of the yarn bundles, resulting in difficulties in exiting, causing hanging yarn and broken ends; or winding the membrane yarn into shape , this method is easy to compress the tow to form an impression, which affects the appearance of the fabric
