Problems solved by technology

[0003] The plastic woven cloth in the prior art is generally woven by a six-shuttle circular machine, that is, a single warp yarn and a single weft yarn are used to interweave on the circular loom. This process is relatively mature, and this process has a prominent disadvantage. : To make products with high tensile requirements, the size of the cross-section of the warp and weft yarns that can only be used for weaving can only be enlarged (mainly to thicken the plastic filaments), that is, the linear density of the plastic filaments that will be used for weaving (unit: weight over length) becomes large enough
However, the manufacturing method provided by this invention also adopts single plastic filament weaving, so the tensile strength of the product manufactured according to this method is not large enough. If the tensile strength is to be increased, the linear density of the single plastic filament can only be increased. Increasing the linear density will lead to more difficult production of plastic wire drawing and weaving processes, and the woven products are thick and hard, with insufficient flexibility
[0005] Therefore, the simple weaving technology and process of the prior art can no longer meet the requirements of technological development.

Embodiment 1

[0021] A kind of embodiment of folding silk weaving method of the present invention is to be used for making plastic braid, and this method comprises:

[0022] Provide a spinning device, such as a flat film extruder, which is provided with a spinning hole for extruding a layer of plastic film.

[0023] Provide a cooling device, such as water cooling device, to properly cool and shape the plastic film.

[0024] Provide a cutting device, such as several blades, for cutting the plastic film into several independent plastic filaments with the same number and the same width.

[0025] Provide a folding device, such as several narrow grooves arranged on a body, these narrow grooves correspond to each plastic filament, the narrow groove has a certain height to accommodate the plastic filament after folding deformation, and its height is preferably It is equal to or greater than the width of the folded wire after folding, and the width of the narrow groove should be less than the widt...

Embodiment 2

[0031] As yet another embodiment of the present invention, the number of folds of the folded yarn can be two folds, four folds or more folds.

[0032]Warp yarn and weft yarn can choose one of them to adopt folded yarn, while the other still adopts single-layer plastic yarn. It is also possible to select the folding yarns for both the warp and the weft yarns, and the folding number of the folding yarns of the warp yarns is different from the folding number of the folding yarns of the weft yarns.

[0033] Folded yarns of different shapes, thicknesses and materials can be used for warp and weft respectively.

[0034] The linear density of the multi-layer plastic yarn is selected from 50 to 70 tex, and the tensile strength of the braided fabric made by this method is above 2000N / 5cm.

Embodiment 3

[0036] As yet another embodiment of the present invention, several groups of narrower plastic filaments that can be directly used for weaving can be drawn out directly from the wire drawing device, without the need for a cutting device.

[0037] The method can be further extended and applied to weaving flat yarns made of materials other than plastics, such as: flat yarns made of fiber, flat yarns made of resin, flat yarns made of metal, or a combination of the above materials.

[0038] The plastic filaments used in the present invention can be directly taken from existing plastic filaments.

[0039] The linear density of the folded wire is selected from 120 to 200 tex. The tensile strength of the braid made by the method is above 1800N / 5cm.

Abstract

The invention discloses a knitting method for folding silk, comprising silking process that one or more than one plastic silk is obtained by silking equipment; folding process that each plastic silk is folded two or more than two times on the wide direction by folding equipment; rolling process that each plastic silk after folding is rolled together to form a folding silk, which can be used as an integration, by rolling equipment; and knitting process that above mentioned silk, as one kind of warp yarn and weft yarn at least is knitted by knitting equipment.

Description

technical field [0001] The present invention relates to a folded wire weaving method and system for preparing plastic braids and the resulting products. More specifically, the present invention relates to a plastic braid that requires high tensile strength, its weaving method and the equipment used. Background technique [0002] For a long time, plastic woven products have been widely used in various industries due to their unique advantages of good strength, low price, waterproof and corrosion resistance. And its product type has also developed into a wide variety of products from the initial single-function covering cloth. Such as woven geotextiles with high strength and good hydrophobicity for highways, pond bottom fabrics for aquaculture, packaging bags for shipping items, etc. These new application areas have higher requirements for the performance of woven products: good toughness, high strength and light weight. [0003] The plastic woven cloth in the prior art is g...
