Abstract
The present invention relates to a kind of high-strength net cloth, which is made of terylene multifilament through processing and the holes of which are rectangular as well as its manufacturing method. The crossing points of warp and weft on the net cloth are cemented together through heating. The manufacturing method of the net cloth includes the following steps: doff, the terylene long threads will become straightened after going through doffer; double twisting, the doff materials will be twisted twice through twister; steam, the twisted materials will be steamed in the steam box; warping, the steamed materials will go through warping machine; reed; weave by machine; sizing, grey cloth will finalize its design on the machine through high temperature with the help of sizing agent. The invention raises the quality of the product and improves the shape of net holes and its stability.
Description
Technical field
The present invention relates to a kind of textiles and manufacture method thereof.
Background technology
Polyester multifilament screen cloth with high strength is mainly used in the liquid filtering of industries such as chemical industry, food, medicine.In the prior art, used screen cloth mainly is made by monofilament, owing to be subjected to the restriction of aspects such as raw material and processing method, this screen cloth exists the shape instability of mesh, the uniformity relatively shorter, mesh in service life of screen cloth to pay no attention to problems such as the stiffness of thinking of product is not enough mostly.
Summary of the invention
The objective of the invention is to seek a kind of polyester multifilament screen cloth with high strength and production method thereof, with the quality that improves product, intensity, the shape of improving mesh and the stability thereof that improves product.
According to design provided by the present invention, this screen cloth is processed by polyester multifilament, and the mesh of screen cloth is rectangle, and in screen cloth, the intertwined point of warp and parallel bonds together mutually through after the HEAT SETTING.
The production method of polyester multifilament screen cloth with high strength is: a, reeling: polyester filament becomes quantitative straightforward person by spooler with original big bobbin; B, double twisting: the straightforward person who gets off from spooler twists by two-for-one twister, and the twist is every centimeter 5～8 twists; C, steaming silk: the raw material after will twisting is placed on and uses steamed, 90 ℃～100 ℃ of temperature, 40～60 minutes time in the steam box; D, warping: the raw material that steamed with steam box passes through the warping machines warping, forms beam of a loom; E, gait: with beam of a loom gait, denting; F, weave: will gait, the beam of a loom of denting weaves on Rapier looms, forms grey cloth; G, typing: grey cloth is finalized the design temperature on the high-temperature shaping machine with setting agent: 170～190 ℃, 30～50 meters/minute of typing speed.
Before weaving back, typing, grey cloth tested to repair knit.
Advantage of the present invention is: 1, select for use terylene to make the raw material of screen cloth, have acidproof preferably, alkaline-resisting, decay resistance, can effectively improve the service life of product.2, adopt polyester multifilament to make raw material, price is lower than single hole silk, after twisting, suitably increases the diameter of raw material, has increased the flexural wave of longitude and latitude intertwined point, and the coefficient of friction between tram, reaches to prevent the stripped thread phenomenon, guarantees the stability of product mesh.3, adopt rectangular filtering holes, compare, not only have same filtering accuracy, and can improve the rate of filtration and production efficiency again with original square filtering holes.4,, improved the stability of mesh cloth mesh and made the stability that is fit to the moulding of various device liquid filter through high-temperature shaping and after increasing the treatment process of stiffness.
The specific embodiment
This screen cloth is processed by polyester multifilament, and the mesh of screen cloth is rectangle, and in screen cloth, the intertwined point of warp and parallel bonds together mutually through after the HEAT SETTING.
The production method of this polyester multifilament screen cloth with high strength is as follows:
A, reeling: the 70D/14F polyester filament is become quantitative straightforward person by spooler with original big bobbin, for the later process double twisting is prepared;
B, double twisting: the straightforward person who gets off from spooler twists by two-for-one twister, and the twist is every centimeter 5～8 twists;
C, steaming silk: the raw material after will twisting is placed on and uses steamed, 90 ℃～100 ℃ of temperature, 40～60 minutes time in the steam box;
D, warping: the raw material that steamed with steam box passes through the warping machines warping, forms beam of a loom;
E, gait: with beam of a loom gait, denting;
F, weave: will gait, the beam of a loom of denting weaves on Rapier looms, forms grey cloth;
G, repair and knit: grey cloth is tested to repair knit.
H, typing: will repair the grey cloth that weaves and on the high-temperature shaping machine, finalize the design temperature with setting agent: 170～190 ℃, 30～50 meters/minute of typing speed.
The effect of per pass operation is as follows:
1, reeling and double twisting: by reeling and two-for-one twister, the 70D/14F polyester filament is increased the twist,, increase the stiffness of screen cloth to improve brute force, frictional force and the elasticity of raw material.
2, steam silk:,, make the raw material typing, do not beat song so must steam with steam by steam box owing to be difficult for weaving after this raw material twisting.Be convenient to warping, weave.
3, warping, gait, weave: the terylene screen cloth that is made into plurality of specifications by K72 magnetic control Rapier looms.Mesh has square and rectangle, especially with slot for well, because the filter efficiency of liquid can be improved in this hole.
4, typing: by high-temperature shaping, can make polyester raw material under certain temperature action, can blend together mutually in the intertwined point of its mesh, makes mesh be difficult for left and right sides slippage; And in type-approval process, allow " KHN " stiffening agent generation effect on the screen cloth, make screen cloth seem stiffening.Be convenient to make various filtering mesh bags, satisfy the use needs on the various device.
Claims (2)
1, the production method of polyester multifilament screen cloth with high strength is characterized in that, a, reeling: polyester filament becomes quantitative straightforward person by spooler with original big bobbin; B, double twisting: the straightforward person who gets off from spooler twists by two-for-one twister, and the twist is every centimeter 5～8 twists; C, steaming silk: the raw material after will twisting is placed on and uses steamed, 90 ℃～100 ℃ of temperature, 40～60 minutes time in the steam box; D, warping: the raw material that steamed with steam box passes through the warping machines warping, forms beam of a loom; E, gait: with beam of a loom gait, denting; F, weave: will gait, the beam of a loom of denting weaves on Rapier looms, forms grey cloth; Crouch and finalize the design: grey cloth is finalized the design temperature with setting agent on the high-temperature shaping machine: 170～190 ℃, 30～50 meters/minute of typing speed form screen cloth; The mesh of described screen cloth is rectangle, and in screen cloth, the intertwined point of warp and parallel bonds together after finalizing the design mutually.
