Description

The double-deck pluse cloth of jacquard weave

The invention relates to a kind of structure of double-deck pluse cloth.This pluse cloth is divided into upper and lower two width after two-layer weave, has each shed open and introduces a latitude, the design feature (taking double-deck on deep pile carpets as typical products) of the fixed U-shaped suede bundle of each latitude.

In double-deck plush production process, upper and lower two-layer fabrics simultaneously with the additional suede inweaving through connecting mutually, overlapping weave in.After having weaved, the suede between levels fabric is through being cut off, and vertical fine hair bundle is separated, and so just producing two width one sides has the fabric of upright fine hair.

For the inweaving of suede warp that connects two-layer ground cloth, can consider single Velveteen hair consolidation structure of single shed open weft yarn introducing method formation that a kind of use selects at first.But in this structure, whenever immersing oneself in suede in the time occurring, just complying with the back side at layer fabric.These temporary transient not nappings immerse oneself in suede through meeting at layer fabric back side emersion.Therefore must strike off in processing and be struck off afterwards.While striking off, there is being also drawn out through the suede bundle of organizing change location in suede of half.Therefore on layer fabric, organize variation place at each suede, just correspondingly occur a zonal fault.Although its layer fabric is second-rate, this have immerse oneself in suede through at single fine hair consolidation structure of bottom surface emersion, still a large amount of production for double-deck on deep pile carpets and other textile-like of quilt in many countries even now, this is because corresponding weaving technology is fairly simple, only needs to adopt common high shed open jacquard to be just enough to form shed open.In addition, the production efficiency of the fixed fabric of single Velveteen hair is higher comparatively speaking, because the every fixed a line suede of weft yarn bundle, result needn't be introduced additional auxiliary weft just can obtain comparatively dense fine hair coverage rate.

In order to offset the low-quality shortcoming of layer fabric being caused by so-called single Velveteen hair consolidation structure, can adopt the fixed fluff structures of a kind of three latitude.This structure also can be made into single shed open weft yarn introducing form on common high shed open jacquard.Different from single weft yarn fine hair consolidation structure, adopt this structure can be by suede through organizing change point to be transferred to two different weft yarns, thereby enter in upper layer of fabric.Although immerse oneself in suede while adopting this structure and must be struck off through being still attached to the back side of layer fabric, can not produce fault striking off layer fabric in operation.Adopt this structure can obtain following benefit: to fall at the end production loss; Reduce in fine hair forming process, certainly also comprise and immerse oneself in the loss of striking off a large amount of very valuable suede footpath materials in process of suede warp, thereby production cost has declined.

In above-mentioned two kinds of consolidation structures, what glow at the layer fabric back side immerses oneself in suede through utilizing as leftover bits and pieces.The quality of drawing together the carpet of valuable villus material for fear of loss and the improvement of this respect, a kind of can having grown up with the double weft fine hair consolidation structure that single shed open weft yarn introducing method is made into.In this structure, immersing oneself in suede is distributed in upper and lower two-layer fabrics when inweaving, and at this moment the upper and lower fabric such as becomes at the weight, and the tow sides of fabric present pattern clearly.But in levels fabric, must have sum nearly the weft yarn of four to form complete suede bundle consolidation structure.Each latitude must be joined a cardboard, and card converts in the intermittence of twice wefting insertion.Because for above-mentioned purpose, lifting-hook on girff always must move to lower position and go to read, so in each of loom turns, girff must complete complete moving up and down, and the rotating speed of the common high shed open loom consequently using is in this case approximately the half in single Velveteen hair consolidation structure situation.

Therefore, people have adopted many double shed weft yarns to introduce the weaving method of mode, the output while weaving to improve double-deck pluse cloth.Obviously,, in each of automatic loom turns, inweaving in the fabric of the upper and lower of being replaced if not weft yarn just gone, but there are two weft yarns to be introduced at the same time in often turning, mutually overlap, inweave separately levels fabric, just can obtain much higher productivity ratio.Double weft fine hair consolidation structure is the simplest a kind of in this weaving technology.This structure can be made into by double shed weft yarn introducing method.But in this structure, due to splitting of the setting of fine hair, or in complete organization circulation, or half complete organization circulation, just there will be the profile of mixed once, thereby can produce more coarse upper surface.

Therefore the three Velveteen hair consolidation structures that, adopt double shed weft yarn to introduce mode are created out.Now in carpet weaving mill the most common employing be this structure.In this weaving technology, between two weft yarns of double weft fine hair consolidation structure, further introduce the 3rd weft yarn.This 3rd weft yarn covered carpet lower surface immerse oneself in suede through and prevent that it from extruding.Although because three weft yarns of needs carry out fixed suede bundle, thereby productivity ratio is relatively low, from technology, aesthetic, economic angle, does not still exist more satisfied substitute to replace this three Velveteen hair consolidation structures at present.

An object of this invention is a kind of fabric construction of development, and this structure is the advantages with the single Velveteen hair consolidation structure being made into by single shed open weft yarn introducing method by the advantage of the three Velveteen hair consolidation structures that are made into by double shed weft yarn introducing method.Thereby in this structure, neither can produce and immerse oneself in the pull-out of suede warp, also there will not be mixing profile, and the weft yarn number of fixed each suede bundle is reduced to minimum.In addition,, although adopted single shed open weft yarn lead-in device, still can produce pattern clearly at the obverse and reverse of levels fabric.

According to the present invention, be divided into bilevel figured plush fabric after providing one to weave.This fabric has each shed open and introduces the structure of a latitude, the fixed U-shaped suede bundle of each latitude, and immerses oneself in suede through inweaving and be distributed among upper and lower two-layer fabrics.

In addition, according to the present invention, provide a kind of double-deck pluse cloth, in this fabric, a continuous suede that forms upper and lower two-layer fabrics is through extending in two-layer fabrics of replacing.This continuous suede warp is through among continuous a series of weft yarn sequence, each sequence weft yarn, comprise the lower weft yarn of two two-layer fabrics and the upper weft yarn of two two-layer fabrics, and have at least one to immerse oneself in suede through adjacent passing between weft yarn up and down in each sequence, whereby, the weft yarn up and down of every layer of fabric tightened up immerse oneself in suede through and make U-shaped suede bundle more firm.

The method of double-deck pluse cloth in this invention of weaving must be included in levels fabric and to use an independent cardboard to control all suede warps of immersing oneself in to every upper and lower weft yarn.

Method like this, can obtain such result-can with single shed open weft yarn lead-in device weave single Velveteen hair consolidation structure double-deck plush structure, this structure is not wasted suede warp, or at the suede warp of wasting layer by layer up and down complete equivalent in fabric.Therefore, this invention combines following advantage:

A) there is the what is called list Velveteen hair consolidation structure that single shed open weft yarn introducing method is made into, and do not immerse oneself in suede through the shortcoming at layer fabric back of the body emersion.

B) for the double weft fine hair consolidation structure of a complete organization circulation, also can be made into by single shed open weft yarn introducing method, and required weft yarn reduces to half simultaneously.

C) can produce the three Velveteen hair consolidation structures that are made into by double shed weft yarn introducing method with cheap many machines.For example: invent each operative employee according to this and can see two or more machine, and each operative employee can only see a double shed machine.

In the method according to this invention, each weft yarn all must have a cardboard.Introduce common weaving in production at single shed open weft yarn, for completing this process, double-lift open shedding jacquard is combined use with corresponding loom.But the stroke of the lifting-hook of the conventional jacquard of this form is inadequate for weaving double-layer fabric.Because double-lift open shedding loom just has the girff stroke that is applicable to produce woven, so in the time being used for double-deck plush and weaving, harness cord and be suspended on harness cord, the weight etc. on harness cord, also has lifting-hook and girff, and their stroke must double.If production efficiency does not reduce, lengthen in the time that the action of stroke must substantially not change and completed, therefore sizable power (can reach several tons in the framework of several meters wide) must be born by the mechanism in machine.

Therefore, improve according to the present invention, if hang a pulley in each castellated plates, and the harness cord being attached thereto guides by pulley.Harness cord one end connects harness cord, and one end and frame firmly connect, and just can just be adapted as single shed open wefting insertion for weaving the double-deck plush jacquard weaving machine of single Velveteen hair consolidation structure for weaving the double-lift open shedding jacquard of common fabric by one.At this moment when lifting-hook is when producing the common stroke lifting of common fabric, harness cord and harness cord are dragged up and down, the twice (movement velocity is also twice) that its distance of passing by is lifting-hook stroke accordingly.

In this method, each independent lifting-hook is determined must have a lifting tackle to coordinate, but this just makes to be added in harness cord, harness cord and weight on lifting-hook and subtracts and be a half, in this way, just can on the double-lift open shedding jacquard of producing for common woven, produce and there is single shed open wefting insertion, immerse oneself in suede footpath and inweave and be distributed in the double-deck pluse cloth of single Velveteen hair consolidation structure of levels fabric.Therefore, if the lifting-hook of corresponding jacquard and harness cord are linked up with above-mentioned pulley, can be, substantially just the fabric of producing the structure proposing in this invention on the machine of producing in enormous quantities.

According to this invention, weft yarn of every introducing all must use an independent perforation card.In order to control necessary motion, consider on average simultaneously and have each time the suede footpath of immersing oneself in of half to inweave in levels fabric, so turning middle punch card, each of loom should be read.The establishment of perforation card can be worked out with artificial with usual way on punch, and also available computers completes.

Now this invention is described below for example so that schematic diagram is for referencial use:

Fig. 1 has shown the double-deck pluse cloth structure of the fixed double weft of a complete organization circulation, is made into by technical so-called single shed open weft yarn introducing method.

Fig. 2 has shown a single latitude consolidation structure according to the present invention.

Fig. 3 has shown the heald structure for the production of the fabric construction in the present invention.

For the suede binding structure in the levels fabric of a complete organization circulation, obtain the words of double weft fine hair consolidation structure by the single shed open weft yarn introducing method in Fig. 1, must there be two weft yarns at every turn, and weave by the single shed open weft yarn introducing method in Fig. 2, only need a weft yarn according to fixed each the suede bundle of this invention.

In the fabric construction of Fig. 1 and Fig. 2, suede footpath 3 is between upper layer of fabric 1 and layer fabric 2, and these suede footpaths are cut off from centre after having weaved.Upper layer of fabric 1 and layer fabric 2 also include leading thread 4 and access node footpath 5, and lower weft yarn 6 and upper weft yarn 7 that the each freedom of weft yarn structure of upper layer of fabric 1 and layer fabric 2 alternately inweaves form.Immerse oneself in suede footpath 8 and 9, half is separately woven into respectively in upper layer of fabric 1 and layer fabric 2 on average.An essential distinction of Fig. 1 and Fig. 2 structure is in the so-called double weft consolidation structure of Fig. 1, and upper weft yarn only plays a part to tighten up immerses oneself in suede footpath 8 and 9, and also comprises every lower weft yarn 6 according to the upper weft yarn 7(of this invention) also there is the function that forms a suede bundle.

Be to immerse oneself in suede according to the feature of this single latitude consolidation structure of being made into single shed open weft yarn introducing method of invention average and be woven in upper layer of fabric 1 and 2 with approximately equal ratio through 8,9.According to the present invention, can obtain making immersing oneself in suede through 8,9 the effect being distributed in levels fabric 1 and 2 that inweaves, be similar to the double weft consolidation structure that the use single shed open weft yarn introducing method in Fig. 1 is made into.In this case, all must there is jacquard weave plate be put into program and be read for each latitude.Owing to inventing according to this, each latitude can produce a suede bundle, and therefore output is just high many than the structure in Fig. 1.Its output is produced with single shed open weft yarn introducing method thatly immerses oneself in the identical of the single Velveteen bundle consolidation structure of suede through glowing at the layer fabric back side.

In order to form shed open when the fabric of producing in this invention, double-lift open shedding jacquard is suitable for adopting.The connector of loom and jacquard is streakline, and the control information of jacquard is passed to harness cord by streakline.Shown in Fig. 3, be suspended on streakline in the castellated plates 11 of jacquard by first line 12, lifting tackle support 13, harness cord 14, harness cord 15 and weight 16 form.On harness cord 15, there is harness eye 17 so that through suede footpath.Broaching tool (not shown) rises lifting-hook after engaging with lifting-hook 18 and passes by form the necessary traverse H of shed open, then falls again.In the time declining, lifting-hook can be parked on base plate 19.Lifting tackle support (in figure total be expressed as 13) is made up of sliding clamp 20 and lifting tackle 21.The length of sliding clamp 20 and first line 12 should be greater than lift stroke H.After size arranges like this, in the time that the lifting-hook 11 being connected is raised, the lower end of first line 12 just can not be drawn out base plate 19, and adjacent lifting tackle support 13, even also always can not block in normal position in relative motion.In the example of Fig. 3, have a bit very important, be that harness cord 14 should guide by lifting tackle, and the upper end with respect to harness cord 15 of harness cord is fixed on a member of machine frame, this member can be used as the bottom support 23 of harness cord carrier, when lifting-hook rises while passing by traverse H, the harness cord 14 that upper end 22 is fixed on harness cord vehicle supports 23 completes the long traverse of 2H, harness eye 17 with the suede through wherein through being raised together same height.The double-lift open shedding jacquard weaving machine that can be just according to said method H by design lifting-hook traverse forms and is equivalent to the shed opening of 2H lifting-hook stroke, and don't makes jacquard overload.
