The free reed of weft yarn curve woven and weaving method thereof and dedicated elas-tic
Technical field
The present invention relates to the weaving technology in the textile technology field, is a kind of weft yarn curve woven and weaving method and isolated plant.
Background technology
Woven mainly with two groups of yarns through being interwoven in length and breadth, be widely used in garment material, decorative fabric and industry lining etc., its weaving process is followed the technological requirement through (vertically), latitude (laterally) yarn square crossing, the warp let-off, opening, the wefting insertion by loom, beats up, batches five big motion coordinated and knit and make grey cloth.Conventional horizontal flat vertical weaving mode makes that the variety design of woven is more single.
Summary of the invention
The object of the present invention is to provide a kind of traditional horizontal flat vertical weaving form, the weft yarn curve woven of the curved formula of fabric weft yarn and weaving method thereof and free reed of dedicated elas-tic of changing.
Technical solution of the present invention is:
A kind of weft yarn curve woven is characterized in that: the curved shape of the weft yarn of fabric.
A kind of weaving method of weft yarn curve woven comprises the warp let-off, opening, wefting insertion, beats up, batches, and it is characterized in that: adopt dent to carry out the crooked free reed of elasticity according to the size of the power of beating up when beating up; Utilize the variation of fabric tissue or the variation of weft yarn thickness, make fabric in the substantial rate generation difference of broadwise on the loom on the same line, cause the power generation difference of beating up, the free reed of elasticity is when beating up, and dent carries out bending according to the size of the power of beating up, and the rate of enriching is big, dent is crooked big, the rate of enriching is little, and the dent bending is little, realizes the weft yarn curve.
The free reed of described elasticity comprises the reed base, the movable dent of dress on the reed base, fixedly connected with the reed base in the lower end of movable dent, movable being arranged on the dent locating slot in upper end of movable dent, the dent locating slot is the outside unscreened open (be bending direction one side of movable dent do not have block), partly fixedlys connected with the fixedly dent of mid portion by the limit reed between dent locating slot body and the reed base.
The free reed of described elasticity comprises the reed base, the movable dent of dress on the reed base, fixedly connected with the reed base in the lower end of movable dent, the upper end of movable dent is movable to be arranged on (upper end that is movable dent can move up and down) in the dent locating hole in the dent locating hole, partly fixedly connected with the fixedly dent of mid portion by the limit reed between dent locating hole body and the reed base.
The present invention changes traditional horizontal flat vertical weaving form, the curved formula of fabric weft yarn, as use coloured yarn will produce beautiful curve pattern, can improve woven kind class.

The specific embodiment
A kind of weaving method of weft yarn curve woven comprises the warp let-off, opening, wefting insertion, beats up, batches, and adopts dent to carry out the crooked free reed of elasticity according to the size of the power of beating up when beating up; Utilize the variation of fabric tissue or the variation of weft yarn thickness, make fabric in the substantial rate generation difference of broadwise on the loom on the same line, cause the power generation difference of beating up, the free reed of elasticity is when beating up, and dent carries out bending according to the size of the power of beating up, and the rate of enriching is big, dent is crooked big, the rate of enriching is little, and the dent bending is little, realizes the weft yarn curve; The curved shape of the weft yarn of the fabric that makes.
The free reed of described elasticity comprises reed base 1, the movable dent 2 of dress on the reed base, fixedly connected with the reed base in the lower end of movable dent, movable being arranged on the dent locating slot 3 in upper end of movable dent, the dent locating slot is the outside unscreened open (be bending direction one side of movable dent do not have block), partly fixedlys connected with the fixedly dent 4,5 of mid portion by the limit reed between dent locating slot body and the reed base.
The free reed of described elasticity can also be another kind of form: comprise reed base 6, the movable dent 7 of dress on the reed base, fixedly connected with the reed base in the lower end of movable dent, the upper end of movable dent is movable to be arranged on (upper end that is movable dent can move up and down with the bending of movable dent) in the dent locating hole 8 in the dent locating hole, partly fixedly connected with the fixedly dent 9,10 of mid portion by the limit reed between dent locating hole body and the reed base.
Operation principle of the present invention:
The rule that warp thread and weft yarn be interlaced, drift along each other is called fabric tissue.Change fabric tissue, fabric tissue, mechanical and physical performance and appearance of fabrics are all had tangible influence.Fabric comprises plain weave, twill and three kinds of tissues of satin weave, based on elementary organization, changed (fly number, prolong interlacing point floatingly longly change waling, two or more tissues are weaved etc. by uniting) and can be developed into alternative construction, united organization, complex organization etc. as changing interlacing point.Under the situation of machine filling density on identical, identical thickness weft yarn, different fabric tissues has different substantial rates on loom, be organized as example for three kinds with plain weave, twill and satin weave, the different substantial rate maximum of plain weave, the substantial rate of twill secondly, the substantial rate minimum of satin weave causes the dent power size variation of beating up.According to above-mentioned feature, when Fabric Design, the partial design of the section that broadwise is different becomes different fabric tissues, replaces as plain weave and satin weave, to obtain the different power of beating up.
The variation characteristic of weft yarn thickness among the present invention: the variation of weft yarn thickness mainly also is the substantial rate generation difference of broadwise on the machine that changes on the loom, cause the generation difference of beating up, the weft yarn crude joint part power of beating up is big, make this regional weft yarn crooked big, the weft yarn detail section power of beating up is little, make this regional weft yarn bending little, realize the weft yarn curve.
