Abstract

The present invention relates to warp knitted square-mesh net and a knitting method thereof. The present invention is characterized in that each root of net twine of a main body and the net twine of an adjacent main body are concurrent in the same net strand weft direction, and are knotted with two net knots. One root of net twine of the main body forms five net strands of two meshes. Two adjacent roots of net twine of the main body form two net strands as the rest, so square double mesh main body is knitted. The net strands of the square double mesh main body are mutually vertical in the warp direction and in the weft direction. The warp knitted square-mesh net is formed by the combination of a plurality of square double mesh main bodies. Net sides on both sides of the warp knitted square-mesh net require two roots of net twine to form knitting the net sides. The net twine on both sides and the adjacent net twine of the main body are alternately folded in parallel, and are knotted with net knots with the adjacent net twine of the main body in the weft direction on the folding point. The warp knitted square-mesh net adopts a single warp double mesh structure, and has simple knitting technology. The warp knitted square-mesh net can be knitted into square or oblong meshes, and can be knitted into a flaky net or a tubular net with a firm mesh structure. The warp knitted square-mesh net is suitable for manufacturing protective nets, enclosure nets, shed covering nets, etc.

Description

Square-mesh is through the netting braid method

Technical field:

The present invention relates to a kind of square-mesh through the netting braid method, belong to weaving knitting skill field.

Background technology:

WEB is the product that a class is widely used at everyways such as industry, agricultural, fishery.Existing rhombus order through the mesh of netting along arrangements that assume diamond in shape through broadwise, institutional framework and braid method such as Fig. 1, Fig. 2, shown in Figure 3, at first nettle 1 intersects to knit a net with nettle 2 and ties a, nettle 1 intersects to knit a net with adjacent left-hand nettle 3 left and ties b ' then; Nettle 2 intersects to knit a net with adjacent right side nettle 4 to the right ties b, last nettle 1 and nettle 2 be the junction knot a ' that knits a net once more, so just constituted a diamond mesh aba ' b ', i.e. the braiding of a cellular construction, a plurality of diamond meshes interconnect and constitute the stable WEB of mesh.Cellular construction by two nettles weave, four adjacent nettle junctions knot that knits a net forms a diamond mesh aba ' b ', is a kind of double ends list mesh structure.The method that this diamond mesh adopts four joints to knit a net and ties connects, and anastomose can be beaten unijunction also can beat binode, and its mesh is firm, and bearing capacity is big.If each warp-wise batches equal in length, then the mesh shape is laterally zygomorphic rhombus, and is promptly tiltedly square; If it is unequal that each warp-wise batches length, then the mesh shape is an asymmetric rhombus up and down.This diamond mesh structure is that the necessary edge of mesh two diagonal warp, broadwise are vertical mutually with the formation characteristics.So its shortcoming is:

(1) mesh diagonal off plumb rectangle mesh is difficult to braiding;

(2) because vertical or horizontal tensile force f ₁Always, can produce mesh and draw phenomenon in, dwindle the mesh effective area by the diagonal of mesh.Therefore the rhombus order is suitable as fishing net through netting, and utilizes the occasion of mesh area not very good as requirements such as protection network, fence net, canopy cover nets as far as possible.

Chinese patent 94241696.1 has been introduced a kind of existing plastics plain weave mesh fabric by retrieval, as shown in Figure 4, this technology is that warp-wise two flat,

plastic guipures

plastic guipures

1,2 and two flat, plastic guipures of broadwise 3,4 or be bonded to one, form anastomose, so just finished a square mesh abcd, a plurality of square meshes interconnect and then constitute the stable plastics plain weave mesh fabric of mesh.Cellular construction is formed by connecting by warp-wise two flat,

plastic guipures

1,2 and two flat, plastic guipures of broadwise 3,4, is the single mesh structure of a kind of double ends double weft.The advantage of this technology is can knit the netting thigh along warp-wise, the orthogonal square or rectangular mesh of broadwise.But the shortcoming of this technology is:

(1) its adopts welding or adhesive method fixing the mesh structure is insecure through broadwise net thigh crosspoint, and the direction bearing capacity is low in length and breadth for wire side, generally is used for making composite or loading direction perpendicular to the packaging bag of wire side etc. more;

(2) braided material and cross sectional shape need be to be suitable for the plastics class flat guipure that welds or bond, and range of application has limitation;

(3) this method can only weave sheet-like web, and can't knit the volume cylindrical net.

Summary of the invention:

The invention reside in the shortcoming of avoiding above-mentioned technology, and the square Nikkei netting braid method that a kind of mesh is firm, technology is simple, production cost is low is provided.

The technical scheme of technical solution problem of the present invention is as follows:

A kind of square-mesh is through the netting braid method, it is characterized in that every main body nettle makes a call to two anastomoses in same net burst broadwise and the junction of adjacent body nettle, a main body nettle constitutes five net thighs of two meshes, adjacent two main body nettles constitute all the other two net thighs, be woven into square pair of mesh of a main body thus, the net thigh of square pair of mesh of main body is vertical mutually along warp-wise, broadwise, and by square pair of mesh combination of a plurality of main bodys.Its both sides selvage needs two nettles of weaving selvage, and it is parallel superimposed that both sides nettle and adjacent body nettle replace, in superimposed place and adjacent weft to the main body nettle knot that knits a net.

Compared with prior art, advantage of the present invention is:

(1) adopt Dan Jingshuan mesh structure, weaving is simple;

(2) can conveniently weave the square or rectangular mesh.Can be woven into sheet-like web or cylindrical net;

(3) braided material and cross sectional shape are suitable for the crooked flexible strand of tiing a knot of various energy, band etc.;

(4) mesh sound construction, bearing capacity is big, wide application.
