Abstract

The invention discloses a woven fabric weft curve fabric and a weaving method. By means of a device capable of controlling the warp supply amount of part of warp, by changing the warp supply amount of warp, the density is changed, and therefore bending deformation happens to weft, and the curve effect is embodied on the cloth surface. By changing the weft density, the traditional ground horizontal flat effect is changed on the aspect of the fabric array of weft, and the curve appearance of weft is generated. By changing the weft density, the beautiful dual-curve pattern can be generated by means of colorful threads, and the variety level of the woven fabric is improved.

Description

Woven weft yarn curve fabric and method for weaving
Technical field
The present invention relates to a kind of woven weft yarn curve fabric and method for weaving.
Background technology
Generally mainly with two groups of yarn Jing, latitude is interwoven woven in length and breadth, and longitudinal direction is referred to as warp thread, is laterally referred to as weft yarn, It is widely used on garment material, decorative fabric and industry articles for use.Its weaving process follows Jing(Longitudinal direction), latitude(Longitudinal direction)Yarn hangs down The technological requirement of orthogonal fork, by the warp let-off of loom, opening, wefting insertion, beats up, batches five big motion coordinated and knit and make base Cloth.Routinely this smooth vertical and horizontal weaving mode so that the variety design of woven is relatively simple.For changing this traditional knitting Method is made so that we mainly by the device that the extraordinary control section warp yarn supplying amount of design is how many, change this situation, made Straight weft yarn is gone to be changed into bending change, to enrich the variety design of woven.
The content of the invention
It is an object of the invention to provide a kind of change traditionally smooth vertical and horizontal weaving mode, can make to weave cloth latitude Yarn bends change, can improve the woven weft yarn curve method for weaving of woven kind class.
The present invention technical solution be:
A kind of woven weft yarn curve fabric, is characterized in that:Formed by the weaving of following method:Using energy control section warp thread The device of warp run-in size, it is how many by changing warp yarn supplying amount, change filling density size, and then make weft yarn bend change Shape, presents J curve effectJ on cloth cover.
A kind of woven weft yarn curve method for weaving, is characterized in that:Using the dress of energy control section warp yarn supplying amount size Put, it is how many by changing warp yarn supplying amount, change filling density size, and then make weft yarn occur bending and deformation, present on cloth cover Go out J curve effectJ;
The device of energy control section warp yarn supplying amount size is made up of three rollers of isosceles triangle, and wherein lower two are Jockey pulley, surface are smooth, and upper one is that warp let-off tension adjustment deforms cam rollers;Warp thread is by lower two jockey pulley holdings, the upper warp let-off Tension adjustment deformation cam rollers warp thread is acted on according to surface outline curves, when the upper warp let-off tension adjustment deformation cam rollers by Cam base circle contour curve to cam pinnacle contour curve operate to warp thread suppressing action when, play a part of reduce warp run-in, Filling density now becomes big;When upper warp let-off tension adjustment deformation cam rollers operate from cam pinnacle contour curve to cam base circle profile When curve acts on warp thread, play a part of to increase warp run-in, filling density now diminishes.
The device of energy control section warp yarn supplying amount size is made up of three rollers of isosceles triangle, and wherein lower two are Jockey pulley, surface are smooth, and upper one is that warp let-off tension adjustment deforms cam rollers, by the Heterogeneous Permutation of axial cam piece, is realized The change in the same section of warp run-in.
A diameter of 20 ~ 40mm of the cam base circle of the cam rollers, a diameter of cam base circle diameter of cam pinnacle profile 2 ~ 4 times.
Transition profile curve from basic circle contour curve to cam pinnacle contour curve is that a variable downlink or uplink is bent Line X, being reflected in warp run-in change is:Normal warp run-in ± [(Distance/2 between two jockey pulleys)2+X2]1/2×2。
The rotating speed of three rollers of device of energy control section warp yarn supplying amount size, need to guarantee two jockey pulley rollers The speed on surface is consistent with warp let-off speed, and warp let-off tension adjustment deforms the rotating speed of cam rollers, can make appropriate change, than two The speed of jockey pulley roller surfaces can have certain speed, depending on the needs that will be changed by cloth cover upper curve.
The present invention is made weft yarn change traditionally horizontal flat effect in fabric arrangement, will produce latitude by changing weft density The curve outward appearance of yarn.Weft density size variation is realized, and beautiful hyperbola pattern can will be produced using coloured yarn, lift shuttle The kind class of fabric.
Description of the drawings
The invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of the device of energy control section warp yarn supplying amount size in the present invention.
