Abstract

The method of weaving double-interval hollow fabric in loom is that in the weaving of complete repeat, all the warp yarns are separated into five groups, at least three groups of the warp yarns are used in weaving the upper, middle and lower layer of the integral interval fabric separately in relatively low warp pacing speed, while the other two groups of warp yarn are used in weaving the connection between upper layer and the middle layer and between the middle layer and the lower layer in relatively high warp pacing speed, so as to form the connection with double-interval hollow fabric structure and weave double-interval hollow fabric with three layers of integral structure.

Description

On the cloth machine, weave the method for double space hollow fabric

Affiliated technical field

The present invention relates to a kind of manufacture method of space fabric, weave the method for double space hollow institutional framework on especially a kind of machine loom, the fabric that is woven into can be used as and has higher caliper, and the enhancing body of the hollow light composite material of standing upright in good condition.

Background technology

The feature of space fabric is: be meant at interval have with two fabrics become certain distance to separate to connect in the middle of the structure sheaf that connects.

The formation method of weaving space fabric can be divided into method of weaving and knitting.

At present, known woven barrier composite material with the manufacture method that strengthens body shown in the patent that patent US005175034A, application number are 00135851.0, though be woven weaving mode, but only be the individual layer spacer structure, when using as composite board, its thickness can not be done greatlyyer, the more restriction that the final use of composite is subjected to.

In the document " institutional framework of three-dimensional woven fabric and design ", the multi-ply fabrics kind has been made comparatively detailed introduction, but the fabric of not mentioned double space structure.

Be knitting weft-knitted space fabric among the patent US2004099016, can only be individual layer spacer structure fabric.

Similarly, related tricot in the document " functional warp-knitted spacer fabric " also can only be limited to the individual layer spacer structure.

Summary of the invention

For overcome the above-mentioned existing individual layer of space fabric on making as composite material reinforcement body at interval the intrinsic restriction on purposes in restriction on the thickness and multiply cloth, the invention provides a kind of method of on the machine loom, weaving double space hollow institutional framework.

The inventive method is to carry out weaving of three layers of overall structure tissue on the machine loom, and leave spacing distance between layer and the layer.For this reason, in the weaving an of complete organization, all warp thread are divided into five groups at least: first group, second group and the 3rd group of warp thread only are used for integrated spaced fabric upper, middle and lower layer respectively, are made into fabric upper, middle and lower layer separately with slower warp let-off speed; The 4th group of warp thread with certain rules appear on the fabric in turn, in the middle level, and has warp let-off speed faster, formation has being connected of hollow space structure the going up of first group of fabric that constitutes with second group of warp thread, middle level, and its change that connects the positive warp let-off speed that length or spacing distance can be by the 4th group of warp thread continuously changes; The 5th group of warp thread with certain rules appear in the fabric in turn, in the lower floor, also has warp let-off speed faster, formation in second group of fabric that constitutes with the 3rd group of warp thread, the having being connected of hollow space structure of lower floor, its change that connects the positive warp let-off speed that length or spacing distance also can be by the 5th group of warp thread continuously changes.

The invention has the beneficial effects as follows, can directly on the machine loom, weave double space hollow organized whole structure, cooperation is selected for use with raw material, such as glass fibre, this fabric can be used as the enhancing body of the hollow light composite material with higher caliper, its final use is extensive, as can be used as high-strength light, heat insulation, composite such as resistance sound etc.

Description of drawings

Fig. 1 is a fabric construction schematic diagram of the present invention.

Fig. 2 is the longitudinal cross-section figure of embodiments of the invention.

Fig. 3 is warp opening movement figure in the complete organization of embodiments of the invention.

Fig. 4 is embodiments of the invention woven drafting plan and line domains on the multi-arm loom.

The specific embodiment

Fig. 1 has represented the fabric schematic diagram of double space hollow organized whole structure.

Fig. 2 is expressed as the longitudinal cross-section figure of the fabric of embodiment, is a whole three-decker tissue, layer with layer between leave spacing distance, just formed the double space overall structure between three layers, have 14 warp thread and three layers of weft yarn are interwoven.

Fig. 3 is warp opening movement figure in the complete organization of embodiment fabric.Have 14 warp thread and be made into, successively from left to right.All warp thread are divided into five groups: first group of upper strata that

warp thread

5,12 is made in the integrated spaced fabric, second group of middle level that

warp thread

6,13 is made in the integrated spaced fabric, the 3rd group of lower floor that

warp thread

7,14 is made in the integrated spaced fabric, these three groups of warp thread are with the slower speed warp let-off; The 4th group of

warp thread

1,3,8,10 appears on the fabric in turn, in the middle level, the going up of fabric, middle level connected into spacer structure with illustrated opening rule; The 5th group of

warp thread

2,4,9,11 with illustrated opening rule appear in the fabric in turn, in the lower floor, with in the fabric, lower floor connects into spacer structure; And fourth, fifth group of warp thread has warp let-off speed faster, and its change that connects the positive warp let-off speed that length or spacing distance can be by fourth, fifth group of warp thread continuously changes.

Fig. 4 is drafting plan and the line domain of embodiment fabric when weaving on the multi-arm loom.The figure on the left side of Fig. 4 represents the state of gaiting when 14 warp thread are worn method according to figure, the line version ordered state the when figure on the right represents to form the required harness motion of Fig. 2 with the pairing heald frame of drafting plan.
