example 1

[0048] Example 1: If figure 1 As shown, the organizational structure adopts 1 upper and 1 lower plain weave, the thickness of the mesh body is 1.10-1.25mm, and the weight is 935g / m 2 ±190.

example 2

[0049] Example 2: If figure 2 shown. The organizational structure adopts 1 upper and 3 lower plain weaves, the thickness of the mesh body is 1.50-1.65mm, and the weight is 870g / m 2 ±190.

example 3

[0050] Example 3: If image 3 , Figure 4 As shown, the organizational structure adopts 2 upper and 2 lower twill weaves, the thickness of the mesh body is 1.30-1.45mm, and the weight is 3325g / m 2 ±380. The herringbone pattern structure is required, and the herringbone pattern (mountain shape) is 40mm-100mm wide.

[0051] (3) Interface processing: check the qualified mesh body, calculate the shrinkage and specification loss in advance according to the specification required by the customer, and then determine the cutting specification, and mark the position of the spiral ring on the mesh surface according to the cutting specification Thread, cut in sections along the direction of the marked line, extract 1-8 weft threads from each incision, and use spiral rings to fill the space left after the weft threads are drawn out at each incision (between 1 and 4 warp threads) ), use 1-6 polyether ether ketone PEEK monofilaments with a diameter of 0.65-0.90mm to pass through the ends...

Abstract

The invention discloses a production technology of a high-thermal-shrinkage net. The technology includes the steps that polyvinylidene fluoride PVDF monofilaments are selected as high-stretching net warp and weft materials; a heavy rapier loom is adopted for weaving warp and weft, wherein the warp is woven through warping of a warp plate, and weft is woven according to a weaving pattern plate graph; finally, a net body is woven; a spiral ring penetrates into chemical fiber monofilaments (such as PEEK monofilaments / PVDF monofilaments) for connector processing, and a high-stretching net finishedproduct is obtained. The product is low in production cost, long in service life, completely suitable for meeting requirement for pulp producing of a modern wet-heat rotary drum machine, and capableof meeting the pulp producing requirement of various wet-process rotary drum machines at home and abroad.

Description

technical field [0001] The invention relates to the field of stretch net processing technology, in particular to a production technology of strong heat-shrinkable net. Background technique [0002] The paper industry is an important part of modern industry, and its products are widely used in modern life. The commonly used papermaking method is wet papermaking, in which pulping is an essential front-end process. Pulping generally requires a vacuum drum washer, and the vacuum drum washer needs to be provided with a mesh body close to the drum surface during the working process. One of the existing nets for vacuum drum washing machines is made of domestic polyester or nylon wire, which is suitable for low-speed and small vacuum drum washing machines; the other is high-speed large-scale vacuum drum washing machines. The mesh body used in the pulp machine currently only relies on imports from abroad. [0003] The mesh body on the drum surface has an important influence on the...
