Abstract

The present invention is forming process of weft-knitted fabric with thin mesh effect. In a weft knitting machine with back needle bed needle and special front needle bed needle capable of raising the loop on the needle, the basic stitch of the looping structure is first knitted with fine yarn in the back needle bed and the setting-on plus missed loop is then knitted with coarse yarn in the back needle bed. The missed loop may cross several needle wales, and the front needle bed needle acts for hanging missed loop only. After several continuous ranks are kitted, the front needle bed needle will raise all the missed loops inside the needle hook and transfer them to the hook of the back needle bed needle for retaining loop. The said process is circulated to form the weft-knitted fabric with thin mesh effect, and the fabric is suitable for use as decorating or fashionable dress material.

Description

A kind of method that forms the weft-knitted fabric of thin saturating big mesh effect

Affiliated technical field

The invention belongs to field of textiles, it provides a kind of knitting weft-knitted complex tissue braid method, and is especially a kind of on the two-needle bar weft-knitting machine, forms the method than the fabric of the saturating mesh appearance effect of Da Bao, and the fabric that is woven into is fit to the usefulness of decoration or fashion material.

Background technology

At present, the known method that forms the mesh tissue on knitting machine is divided into through compiling and weft-knitted two kinds, and they respectively have characteristics.

Wherein, use morely through the volume method, weft-knitted method is less.

Kind and method through compile forming eyelet are various and easy, for example only just can form mesh and have organized through compiling single comb.This is because on being organized in institutional framework and when weaving, be easy to just accomplish not contact between some knitting needle stringer in the line scope of eyelet effect requirements, and these unrelated places just present orifice effect behind the machine under the fabric, and the mesh that forms can be bigger.But the eyelet fabric through the volume method forms exists following shortcoming on the top-grade fashion lining: braiding based on chemical-fibres filaments, is difficult to use feel and appearance effect natural fabric preferably with yarn, weaves as cotton, fiber crops and wool fibre; Practical warp knitting fabrics is the above tissue of two combs normally, and technological design and last machine debugging difficulty are bigger, production technology and flow process complexity; Equipment investment and production cost are higher.

The kind and the method for weft knitting formation eyelet are less, and be difficult, and the mesh that forms is less.This is because weft knitting on institutional framework and when weaving, yarn is continuous in proper order on the normally line direction, stringer direction upper sleeve through links to each other, this just is difficult to form the eyelet effect on principle, because there is not the leap of yarn in presenting on requirement or line direction or the stringer direction of eyelet or wears contact.Realize weft-knitted eyelet, existing technological means and tissue have tuck, pineapple or leno.But the deficiency that exists is: the little and out-of-flatness of eyelet that tuck forms; The realization of pineapple or leno needs complicated loop-forming element, mechanism and control, and inefficiency.As seen, weft knitting is difficult to form the thin mesh effect of larger area bulk.

Summary of the invention

In order to overcome the deficiency that weft knitting is difficult to form big eyelet effect, the invention provides a kind of method of weft-knitted fabric of the thin mesh effect that forms the larger area bulk.

The technical solution adopted for the present invention to solve the technical problems is: have back needle-bed knitting needle and have particular design, on the weft machine of the front needle bed knitting needle lifted on can be with the coil on the pin, at first, on the needle-bed knitting needle of back, carry out the braiding (fine yarn is made stitching thread) of the ground tissue of loop-forming structure with fine yarn, on the needle-bed knitting needle of back, carry out the braiding (coarse yarn is made laying-in thread) that tuck adds flotation line with coarse yarn, flotation line can be crossed over a plurality of knitting needle stringers, and front needle bed knitting needle only plays the hook flotation line; So several lines of continuous weaving, around here, the flotation line of hook on front needle bed knitting needle both can be single, also can be many and be collected at together; Then, front needle bed knitting needle will be lifted on all flotation lines in pinhock, shift on the pinhock that is suspended to the back needle-bed knitting needle, and back needle-bed knitting needle carries out tuck.As the method circulation braiding, form the fabric with thin saturating big mesh effect of full wafer.

Use two kinds of yarn purposes of thickness to be in the technical solution of the present invention: thin yarn weaves in due form, to guarantee that knitted fabric loop wears mutually, forms the overall structure that neither can decoherence, and has the ground tissue of thin saturating effect again; Thick yarn weaves in the mode that tuck adds flotation line, tuck is to be attached to thin thin ground tissue for coarse yarn being hung, flotation line is not get in touch in order to organize with ground in the certain-length scope, gather so that in braiding afterwards, can will be the coarse yarn of flotation line state, appear the ground tissue of the thin effect in big zone.The thickness yarn combination just can make fabric form the thin mesh effect of larger area bulk together like this, and fabric integral body is not decoherenced.Exactly because ben these coarse yarns play a major role covering on the sight line, its distributional pattern in fabric also just reflects into artistic effect.

The invention has the beneficial effects as follows, opened up weft-knitted product category, can on the two-needle bar weft machine, produce the fancies of the thin saturating mesh effect of larger area.This be because, because the flotation line of inlay thread is striden many lines tuck, exposed the ground tissue better, thin effective thoroughly; Because it is to stride many stringers pad yarn, so the scope of the mesh effect that it forms is bigger; Because adopt thinner yarn to organize, thicker yarn is made the effect yarn with doing, outstanding more thin saturating mesh effect.
