Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] Such as figure 1 and figure 2 Shown is a cylindrical alkali-resistant polypropylene fabric, which is a continuous cylindrical fabric woven from polypropylene. The fabric has a warp density of 120 threads / inch and a weft density of 33 threads / inch.

[0021] The total number of layers of the braid is 7 layers, and the braid is composed of the first layer of warp yarn 1, the second layer of warp yarn 2, the second layer of warp yarn

[0022] Three layers of warp yarn 3, fourth layer of warp yarn 4, first layer of weft yarn 5, second layer of weft yarn 6, third layer of weft yarn 7 interweave to form a three-dimensional continuous cylindrical braid, the first layer of warp yarn 1 or the second layer The warp yarn 2 or the third layer of warp yarn 3 or the fourth layer of warp yarn 4 all pass through other layers of warp yarn, a...

Abstract

The invention discloses a piece of cylindrical alkaline-resistant polypropylene fabric which is a continuous cylinder made of polypropylene through knitting. According to a manufacturing method for manufacturing the cylindrical alkaline-resistant polypropylene fabric, weaving is conducted through a three-dimensional multi-layer cylindrical fabric knitter, all layers of warp yarn are placed on bobbins on the two sides of a creel, each layer of warp yarn interweaves with the corresponding layer of weft yarn entering a corresponding suspension type yarn guide device and enters a cylindrical collecting and knitting pipe of a collecting and knitting device after entering a corresponding opening of an opening device, and three-dimensional multi-layer cylindrical knitting is completed after collecting and knitting are conducted through the collecting and knitting device. By means of the process of winding multiple layers of fiber, the cylindrical fabric can be directly knitted without sewing the opening position of the cylindrical edge, all faces of the manufactured cylindrical fabric bear force evenly, the structure is compact, and the fabric can better adapt to high-temperature and high-pressure filtering.

Description

[0001] technical field [0002] The invention belongs to the technical field of fabric weaving, in particular to a cylindrical alkali-resistant polypropylene fabric and a manufacturing method thereof. [0003] Background technique [0004] Conventional polypropylene fabric can only be flat. In the process of making cylindrical filter bags, both sides of the fabric need to be stitched to form a cylindrical shape. The cylindrical fabric has seams due to uneven stress at the sewing place, and the structure is not tight, which will directly affect the filtration efficiency and service life of the filter bag. Moreover, in the process of filter bag processing, since the opening of the cylinder side needs to be stitched, it directly affects the production efficiency. Therefore, how to weave a cylindrical fabric so as to be better suitable for high-temperature and high-pressure filtration has become the direction of efforts of those skilled in the art.
