Abstract

A jacquard loop weaving method simulating burnt-out effect on a double-side knitting weft machine is to arrange every two groups of loops in a full-flat-row on the machine. In first group, all disk needles do not go out and all cylinder needles feed the ground bear yarns after quiting from loops, then the knitting needless fall down but don't unhook and all hooks of the cylinder hold the ground yarns, then in the second group, some cylinder needles are selected again to feed loop bear yarns, and all disk needles go out to hold the loop threads, the selected needles hook the ground yarns on the first group bearing and loop yarns on the second to fall down quiting and looping, at the brnt-out simulation effect spots without loops their corresponding cylinder needles are not selected and remain at the height of the first group fall down but not catch the loop yarns which are at the back of the texture in suspension.

Description

The braid method of imitative etching effect knitted velvet article

Affiliated technical field

The present invention relates to a kind of preparation method of knitted jacquard looped pile, especially the method for the imitative etching effect jacquard weave looped pile of braiding on double knit circle latitude machine.

Background technology

The imitative etching effect jacquard weave pile stitch of weft knitting is the fabric construction that is formed by two kinds of loop constructions: the looped pile structure is made of jointly wire gauze with short sinker loop and the terry yarn with long sinker loop; The unfertile land loop construction, single thread line weft plain weave only be made of wire gauze, and loopy yarn is the flotation line state, and by after being cut off, the flat thin tissue of remaining wire gauze latitude only just has the hollow out effect of imitative etching effect to this flotation line in the shorn velvet operation.Though imitative etching effect jacquard weave looped pile has comparatively unique hollow out carving appearance effect behind shorn velvet, thin saturating ground tissue combines with abundant velvet flowers and forms the three-dimensional pattern effect, has application promise in clinical practice taking and decorate with the field, but its complexity and special organization structure, the machine that makes it possible to produce it is less, and the breach of required production capacity is bigger.

At present, the braiding of imitative etching effect jacquard weave looped pile is to adopt German MAYER﹠amp on the known knitting circular knitting machine; The MCPE2.4 type polychrome jacquard weave looped pile single face large circle machine of CIE company.But this machine is the special-purpose single face machine of imitative etching effect jacquard weave looped pile, bigger to the fertile product variety restriction of institute, and, must in the same sedimentation film trap of the sinker bar of machine, insert two different sinkers side by side, sinker holding and pulse sinker, and separately motion control triangle must be arranged are with the cooperatively interact motion of the different rules of having relatively high expectations of formation, mechanism's complexity, manufacturing cost is higher.In addition, the adjustment of terry height is finished by changing sinker, and is more bothersome, and the sinker that needs different size is as spare part.

Summary of the invention

In order to overcome the restriction that imitative etching effect jacquard weave looped pile can only use the round latitude machine of the special-purpose single face with two kinds of different sinkers to weave, overcoming prior art can not use to such an extent that develop the deficiency of imitative etching effect jacquard weave knop cloth on the double-faced jacquard circle latitude machine that has a large capacity and a wide range, the invention provides a kind of weaving method of on double knit circle latitude machine, imitating etching effect jacquard weave looped pile, make and promptly have the thin saturating characteristics of base fabric, have the appearance effect of three-dimensional looped pile lint again concurrently, soft, can be used as DINNER JACKET and ornamental newer fabric product can be low-cost, produce in large quantity.

The technical solution adopted for the present invention to solve the technical problems is: carry out the lopping braiding of an imitative etching effect jacquard weave looped pile line completely with every two-way of double-faced jacquard circle latitude machine; In the first via, all coverers do not go out pin, and all cylinder knitting needle is fed the pad wire gauze moving back the circle back, and knitting needle descends but not knocking over promptly maintains wire gauze in the pinhock of all cylinder knitting needles subsequently; Then in the second the tunnel, selectively the cylinder knitting needle at looped pile place is chosen once more and fed the pad terry yarn, all coverers go out pin and hold loopy yarn to put simultaneously, the knitting needle of choosing subsequently hook simultaneously hauls terry yarn decline knocking over and the lopping that the wire gauze and the second tunnel on the first via pad fills up, and at the base fabric place of no looped pile, corresponding cylinder knitting needle is not chosen and is remained on the height that the first via descends that pad is less than loopy yarn, and the reverse side that loopy yarn then is positioned at fabric tissue is the flotation line state.At coverer terry yarn is put and to be held and wire gauze is not had under the differentiation of effect, form wire gauze and have the pile stitch of the terry yarn of long sinker loop with short sinker loop; So, just form single face flotation line jacquard weave knop cloth.This fabric is through behind the loop cutting machine shorn velvet, and the looped pile place is cut into lint, and after the loopy yarn of flotation line state cuts off, imitative etching effect effect.

The invention has the beneficial effects as follows, can use on the double knit jacquard circular knitting machine that has a large capacity and a wide range by to the repacking of triangle and the adjustment of thread-carrier position, form the ability of producing imitative etching effect jacquard weave looped pile, changed imitative etching effect jacquard weave knop cloth and can only increase the fertile product variety of double knit jacquard circular knitting machine by the restriction of special-purpose single face circle latitude machine production.

Among the figure: 1. cylinder knitting needle, 2. dials knitting needle, 3. wire gauze, 4. wool yarn, 5. cylinder knitting needle syringe needle movement locus 6. grips line, 7. dials knitting needle syringe needle sports level line, the 8. height and position line that rises on the second tunnel of cylinder knitting needle syringe needle, a. first via, b. the second tunnel.

The specific embodiment

The specific embodiment and step that the present invention weaves imitative etching effect jacquard weave looped pile are as follows: use the cyclinder needle 1 of vertical state and the coverer 2 (Fig. 1) of level on the weft-knitting machine, the line of an imitative etching effect jacquard weave pile stitch of two-way braiding.In first via a, all coverers 2 do not go out pin, and all cylinder knitting needle 1 is fed pad wire gauze 3 moving back the circle back, and knitting needle 1 descends but not knocking over promptly maintains wire gauze 3 in the pinhock of all cylinder knitting needles 1 subsequently; Then in the second road b, selectively the cylinder knitting needle 1 at looped pile place is chosen once more and fed pad terry yarn 4, all coverers 2 go out pin and hold loopy yarn 4 to put simultaneously, the knitting needle chosen subsequently 1 hook simultaneously hauls wire gauze 3 on the first via a pad and terry yarn 4 decline knocking over and the lopping on the second road b pad, put at 2 pairs of terry yarns 4 of coverer and to hold and wire gauze 3 is not had under the differentiation of effect, formation has the wire gauze of short sinker loop and has the pile stitch of the terry yarn of long sinker loop, the loop construction shown in Fig. 2 b; And at the base fabric place of no looped pile, corresponding cylinder knitting needle 1 is not chosen and is remained on the height that the first via descends pad less than loopy yarn 4 the second the tunnel, the reverse side that 4 of loopy yarns are positioned at fabric tissue is the flotation line state, becomes the no looped pile structure by single ground yarn weaving shown in the middle part of Fig. 2 c; So, just form single face flotation line jacquard weave knop cloth.This fabric is through behind the loop cutting machine shorn velvet, and the looped pile place is cut into lint, and after the loopy yarn of flotation line state cuts off, imitative etching effect effect.As a comparison, Fig. 2 a is depicted as the two yarn coil structures of traditional jacquard weave pile stitch at no looped pile position, i.e. loopy yarn and wire gauze and lump together lopping.

The 5 syringe needle movement locus that are expressed as cylinder knitting needle 1 among the figure, 6 grip the line altitude line during for the expression braiding, and 7 are expressed as dials knitting needle 2 syringe needle sports level lines, the height and position line that 8 syringe needles that are expressed as cylinder knitting needle 1 rise on the second tunnel.

The height that cyclinder needle 1 descends after first via effect should design and regulate to such an extent that reach following requirement: the second the tunnel, makes terry yarn 4 satisfy pad only and feeds under the condition in the pinhock of the cyclinder needle of the high position of choosing, and high as much as possible.Last figure () among Fig. 1 shows that cyclinder needle 1 drops to higher position m after first via effect, and figure below (two) shows that cyclinder needle 1 drops to lower position n after first via effect.If this position is too high, just can not guarantee that lower position syringe pincushion do not go up terry yarn, as above shown in the figure (); If this position is too low, just can not guarantee the not knocking over after the wire gauze 3 on pad of lower position cyclinder needle, shown in figure below (two).

The looped pile of fabric or the height of lint can be regulated by moving up and down of dials.
