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
Technical field
The invention belongs to weaving textile technical field, particularly relate to the alkaline-resisting polypropylene fabric of a kind of cylindrical shape and manufacture method thereof.
Background technology
Conventional polypropylene fabric can only be plane, and in making cylinder filter bag process, fabric both sides need sew up and be shaped cylindric.This cylindraceous fabric is due to sewing place unbalance stress, and seam, structure is not tight, directly can affect filter efficiency and the service life of filter bag.And in filter bag processing, because cylinder limit opening part needs to sew up, directly affect production efficiency.Therefore, how to knit out a kind of leno cellular, thus be better applicable to High Temperature High Pressure and be filtered into direction in order to these those skilled in the art make great efforts.
Summary of the invention
For above-mentioned the deficiencies in the prior art part, the invention provides the alkaline-resisting polypropylene fabric of a kind of cylindrical shape and manufacture method thereof, solve the fabric sewing place unbalance stress of existing craft woven, seam, structure is not tight, and then affect crawler belt filter efficiency and service life, and the technical problem that production efficiency is not high.
The technical solution used in the present invention is:
The alkaline-resisting polypropylene fabric of a kind of cylindrical shape, this fabric is the continuous print cylindrical shape woven by polypropylene fibre.
Further, described fabric is the solid be intertwined to form by more than three layers warp thread and two-layer above weft yarn
Continuous print circular knit thing.
Further, other layer of warp thread more than two-layer worn by every layer of warp thread of described braided fabric, and every layer of warp thread and other layer of warp thread are successively worn successively around and surround continuous print cylinder, and every layer of orthogonal buckle of weft yarn is in each layer warp thread and surround continuous print cylinder.
A kind of manufacture method manufacturing the alkaline-resisting polypropylene fabric of above-mentioned cylindrical shape, stereoscopic multi-layer leno cellular braiding machine is adopted to weave, whole layer warp thread all placed by creel both sides yarn cylinder, entering the tubular of incorporating device into own forces to the every layer of weft yarns entering corresponding floated feed carrier after every layer of warp thread enters shedding motion respective openings and incorporate pipe into own forces, having incorporated the columnar braiding of stereoscopic multi-layer into own forces by incorporating device into own forces.
Compared with prior art, the invention has the advantages that: adopt multi-layer fiber winding process, directly knit out leno cellular, cylinder limit opening part is no longer needed to sew up, the tubular fabric produced each uniform force, close structure, can better be applicable to High Temperature High Pressure and filter.

Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
As depicted in figs. 1 and 2, the alkaline-resisting polypropylene fabric of a kind of cylindrical shape, this fabric is the continuous print cylindrical shape woven by polypropylene fibre.This fabric through close be 120 pieces/inch, filling density is 33 pieces/inch.
Total number of plies of this braided fabric is 7 layers, and braided fabric is by ground floor warp thread 1, second layer warp thread 2,
The cylindric braided fabric of three-dimensional continuous print that three layers of warp thread 3, the 4th layer of warp thread 4 and ground floor weft yarn 5, second layer weft yarn 6, third layer weft yarn 7 are intertwined to form, ground floor warp thread 1 or second layer warp thread 2 or third layer warp thread 3 or the 4th layer of warp thread 4 are all worn around other layer of warp thread, every layer of warp thread and other layer of warp thread are successively worn successively around and surround continuous print cylinder, and ground floor weft yarn 5 or second layer weft yarn 6 or the orthogonal buckle of third layer weft yarn 7 are in each layer warp thread and surround continuous print cylindrical shape.
A kind of manufacture method manufacturing the alkaline-resisting polypropylene fabric of above-mentioned cylindrical shape, stereoscopic multi-layer leno cellular braiding machine is adopted to weave, creel 8 both sides yarn cylinder is all placed with ground floor warp thread 1, second layer warp thread 2, third layer warp thread 3, 4th layer of warp thread 4, ground floor warp thread 1, second layer warp thread 2, third layer warp thread 3, 4th layer of warp thread 4 enters shedding motion 9 respective openings, ground floor weft yarn 5, second layer weft yarn 6, third layer weft yarn 7 enters corresponding floated feed carrier 10, enter the tubular of incorporating device 11 into own forces to the every layer of weft yarns entering corresponding floated feed carrier 10 after every layer of warp thread enters shedding motion 9 respective openings and incorporate pipe into own forces, the columnar braiding of stereoscopic multi-layer has been incorporated into own forces by incorporating device 11 into own forces.This fabric needs, through high-temperature hot sizing, to strengthen the telescopicing performance of filter cloth, scalable 2 meters long; And the surface smoothness of fabric is improved through press polish process.
As shown in Figure 3, a kind of stereoscopic multi-layer leno cellular braiding machine, this braiding machine has creel 8, shedding motion 9, floated feed carrier 10, band tubular incorporate pipe into own forces incorporates device 11 into own forces, creel 8 both sides are provided with the yarn cylinder for placing whole layer warp thread, shedding motion 9 is for penetrating warp thread, shedding motion 9 is symmetrical set, floated feed carrier 11 is for penetrating weft yarn, floated feed carrier 11 suspends and is arranged in the interval of every two-layer warp thread, the left-right asymmetry setting of floated feed carrier 11, floated feed carrier 11 is positioned at inside shedding motion 9.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
