The number that penetrates of the fabric is set to 2 and enters/dent according to the tissue of the fabric and product style.

9th, weaving process

The selection of loom:From the GA747 looms system of knitting.This fabric warp has three systems, and difficulty of weaving is big, raw material T/ R mixed yarns, easily there is electrostatic, shed open is not easy clearly, to weave from high speed loom, low production efficiency, thus selects low speed sword The bar loom system of knitting.From GA747 looms knit system still yet another advantage is that:Weft yarn is elastic force composite yarn, is weaved using rapier loom, Sword head is strong to the control ability of weft yarn, weft yarn will not untwisting, when stockinette knits processed, easily caused by naked silk and hollow silk defect Point, it can be avoided by.GA747 loom optimums knit institutional framework complexity processed, the big fabric of difficulty of weaving;

Three axles are weaved:This fabric has three warp systems, and table is through being plain weave, and radical is more, and shed open is not easy clearly, to make With the original feeding system of warp of GA747 looms;Back warp is four pieces and becomes then satin weave, the half that warp thread radical passes through for table, interleaving degress It is few, the warp let-off is controlled using frictional force, warp beam is arranged on the top of the back rest, will be in 12cm or so away from rear depth of beam, this distance Can not be small, passed through because band yarn will be also passed through between back warp from table;Band yarn is not placed on back rest rear with weft yarns, band yarn axle Ground, it is the same with back warp, using frictional force control the warp let-off.

Reverse side is weaved:Because table is more through radical, interleaving degress is also more, and shedding is frequent, thus is weaved using reverse side.Using anti- Face is weaved, and can reduce shedding number:When knitting back weft processed, table lifts through needing, after reverse side weaving, under table more than radical is through becoming Layer fabric, when knitting back weft, it is no longer necessary to lift.The effect of the following aspects can be obtained using reverse side weaving:1. make shed open It is easily clear, beneficial to wefting insertion;2. reduce warp end break;3. beneficial to saving power consumption.

Increase Side End Number:Weft yarn is elastic force composite yarn, crimping fault is easily produced during weaving, to ensure that it is good that fabric is formed Good selvedge, during one side warping, add the tension force of side warp thread;On the other hand Side End Number is increased to increase side yarn to latitude The controling power of yarn, form good selvedge.

Early opening:280 ° of openings.Warp thread has three systems, and it is big to weave into difficulty, and shed open is not easy clearly, using the early work that is open Skill, it is clear to be advantageous to shed open.

Evening enters sword:80 ° are entered sword, and GA747 looms enter sword using 75 ° more.When this fabric knits processed, it is because warp thread has three System, it is clear that opening is not easy, and easily produces side three and jumps fault.To prevent that side three is jumped, will enter the sword time is adjusted to 80 ° and enters sword, makes The increase of shed open effective depth is obtained, is avoided that faults are jumped in generation three.

The low back rest:When two-layer fabric knits back weft processed, the top line of layer fabric, easily sink, cause opening unclear, sternly Constantly warp can be even produced during weight and is stopped, when knitting back weft processed to reduce, the sinking of top line, using the low back rest, to subtract The tension difference of few levels warp thread, increases the tension force of top line, reduces the sinking of top line.

Short shed open:Warp stop frame is moved into most inner side, reduces the length of rear portion shed open, it is comprehensive flat after rear portion shed length is reduced When warp tension it is constant, during shed open full gate, yarn tension increase is advantageous to that shed open is clear, beneficial to the sinking for reducing warp thread.

Move back the sword time:When connecing latitude sword and exiting shed open, angle residing for loom is moves back the sword time.When non-stretchable fabric knits processed, Weft yarn screen resilience is small, and it is identical with opening time to move back the sword time, connects latitude sword and exits shed open, and weft yarn is released, and weft yarn is clamped by warp thread, Realize warp and weft interweaving.When Filling-wise Elastic Fabric knits processed, because weft yarn screen resilience is big, if it is identical with opening time to move back the sword time, Connecing latitude sword and just exit shed open, weft yarn is released, and now, warp thread can produce retraction to the chucking power also very little of weft yarn, weft yarn, Side looped weft fault is formed at the selvedge of right side.When Filling-wise Elastic Fabric knits processed, 5 ° -10 ° more late than opening time of sword time is moved back, is so connect When latitude sword exits shed open, the chucking power of warp thread is bigger, can prevent looped weft fault.Move back evening sword time, warp thread clamps to weft yarn Power is big, and moving back the sword time can not be late again, moves back the sword time too late, can draw weft yarn apart from right side selvedge 10-15cm place It is disconnected, form fault.

Weft yarn discharges length:When fabrics in general knits processed, weft yarn release length is:Upper machine reed width+5-6cm, stockinette are knitted When processed, in upper machine reed width+10-12cm, this fabric weft yarn is full elastic fabric for weft yarn release length control, and weft yarn release length controls In upper machine reed width+12cm, to prevent the generation of right edge looped weft.

Waste selvage yarn radical:The crimping of fabric, side looped weft fault, mostly occur in the right side selvedge of fabric, therefore prevent side latitude Contracting, crimping fault, mainly take measures in the right technique of fabric.We increase to the radical of the right waste selvage yarn by 16 After 20, right side slitter edge well can just clamp elastic force latitude, fabric is formed good selvedge.

Hightension:When this fabric knits processed, knitted using counter, the table more than interleaving degress is original by GA747 looms through being placed on lower floor Let-off mechanism control.When knitting layer fabric processed to reduce, the sinking of top line, warp tension wants control bigger than normal, to reduce The possible sinking of warp thread.When knitting processed, tension weight hammer stem both sides respectively configure 5kg tension weight, the tension force bullet of let-off mechanism Spring force control bigger than normal.

The trimmed size of 3 fabrics:

Fabric width is 59/60inch, after washing through it is close be 121 pieces/inch, finished product through it is close be 126 pieces/inch;Washing Filling density is 94 pieces/inch afterwards, and finished product filling density is 97 pieces/inch.It is 5%, dyeing and finishing width shrinkage 4%, the contracting of lower machine width to wash width shrinkage Rate 17%, long shrinkage is washed as 3%, the long shrinkage 3% of dyeing and finishing, latitude crimp 2.2%.

The present invention is not limited to above-mentioned preferred forms, and anyone can show that other are various under the enlightenment of the present invention The product of form, however, make any change in its shape or structure, it is every that there is skill identical or similar to the present application Art scheme, is within the scope of the present invention.

    (6) warping
    From GA121 beam warpers, during speed of beaming 400m/min, T/R blend fabric warping, to improve warp quality, Using collective's creeling, tension force zone configuration;Front-seat tension washer 13g, middle row 12g, heel row 11g, side yarn 16g;
    Warp thread has three systems, table warp, back warp, band yarn, and textura epidermoidea is plain weave, and nexine is organized as four pieces and becomes then satin weave, band yarn It is not involved in interweaving, is clipped among two-layer fabrics, thus it is different through crimp, it is necessary to the weaving of three axles, difference warping;
    One flower circulation 32, wherein, table is through 40S/ 2 doublet cords 16, back warp 30S/ 2 doublet cords 8, band yarn 30S/ 2 doublet cords 8 Root, full width 223 are spent;Side yarn is 40S/ 2 doublet cords 112, and table, through warping together, table is through 3568+112=3680 of radical Root, back warp radical 1784, band yarn radical 1784, bobbin cradle capacity are 768, and table is through 40S/ 2 are with axle:736*5, back warp 30S/2, it is with axle:594*1+595*2, band yarn 30S/ 2 with axle be 594*1+595*2;
    And axle (7)
    Using XB150 type warp rebeaming machines, and axle speed is 100m/min, and axle tension force is 100kg;
    (8) pass
    For table through being plain cloth, warp thread radical is more, and it is clear that opening is not easy, and is placed on proparea, comprehensive with 1-2 pages, and back warp is four pieces of changes Then satin weave, comprehensive using 3-9 pages, band yarn is not involved in interweaving, and comprehensive using page 10, Side End Number is few, amounts to only 112, uses 11-12 pages comprehensive;One circulation in, the 1-2 pages it is comprehensive, page 10 it is comprehensive, each circulate 8 yarns, comprehensive the 5-9 pages of page 3 through comprehensive, each Circulate 1 yarn, the comprehensive often circulation 2 of page 4;The 1-2 pages comprehensive, comprehensive, every page of heald number 1784 of page 10, the heald number 446 of page 4 Root, page 3, the 5-9 pages comprehensive, every page of heald number 223, side yarn be through page 11,12 it is comprehensive, 56 every page;According to the fabric The number that penetrates of the fabric is set to 2 and enters/dent by tissue and product style;
    (9) weaving process
    The selection of loom:From the GA747 low speed rapier looms system of knitting;
    Three axles are weaved:This fabric has three warp systems, and for table through being plain weave, radical is more, and shed open is not easy clearly, to use The original feeding system of warp of GA747 looms;Back warp is four pieces and becomes then satin weave, and warp thread radical is the half of table warp, and interleaving degress is also few, The warp let-off is controlled using frictional force, warp beam is arranged on the top of the back rest, will be in 12cm away from rear depth of beam, and this distance can not be small, Because band yarn will also be passed through between back warp from table and passed through;Band yarn is not placed on the ground at back rest rear with weft yarns, band yarn axle, It is the same with back warp, the warp let-off is controlled using frictional force;
    Reverse side is weaved:Because table is more through radical, interleaving degress is also more, and shedding is frequent, thus is weaved using reverse side, knits back weft processed When, table lifts through needing, and after reverse side weaving, the table more than radical is through becoming layer fabric, when knitting back weft, it is no longer necessary to lift, because This can reduce shedding number;
    Increase Side End Number:Weft yarn is elastic force composite yarn, crimping fault is easily produced during weaving, to ensure that it is good that fabric is formed Selvedge, during one side warping, increase the tension force of side warp thread;On the other hand increase Side End Number, to increase control of the side yarn to weft yarn Power processed, form good selvedge;
    Early opening:280 ° of openings, warp thread have three systems, and difficulty of weaving is big, and shed open is not easy clearly, using early opening process, to have It is clear beneficial to shed open;
    Evening enters sword:GA747 looms enter sword using 75 ° more, and when this fabric knits processed, because warp thread has three systems, opening is not easy clear It is clear, easily produce side three and jump fault, to prevent that side three is jumped, will enter the sword time is adjusted to 80 ° and enters sword so that shed open effective depth Increase, it is avoided that fault is jumped in generation three;
    The low back rest:When two-layer fabric knits back weft processed, the top line of layer fabric, easily sink, cause opening unclear, when serious Constantly warp can even be produced and stopped, when knitting back weft processed to reduce, the sinking of top line, using the low back rest, with reduction The tension difference of lower layer warp yarns, increase the tension force of top line, reduce the sinking of top line;
    Short shed open:By warp stop frame move to most inner side, reduce rear portion shed open length, rear portion shed length reduce after, it is comprehensive usually on Machine tension force is constant, and during shed open full gate, yarn tension increase is advantageous to that shed open is clear, beneficial to the sinking for reducing warp thread;
    Move back the sword time:When Filling-wise Elastic Fabric knits processed, 5 ° -10 ° more late than opening time of sword time is moved back, latitude sword is so connect and exits shed open When, the chucking power of warp thread is bigger, can prevent looped weft fault;
    Weft yarn discharges length:Weft yarn release length control is in upper machine reed width+12cm, to prevent the generation of right edge looped weft;
    Waste selvage yarn radical:The crimping of fabric, side looped weft fault, mostly occur in the right side selvedge of fabric, therefore prevent side looped weft, volume Side fault, mainly taken measures in the right technique of fabric, it is right after the radical of the right waste selvage yarn is increased into 20 by 16 Side slitter edge well can just clamp elastic force latitude, fabric is formed good selvedge;
    Hightension:When this fabric knits processed, knitted using counter, the table more than interleaving degress is sent through being placed on lower floor by GA747 looms are original Through mechanism controls;When knitting layer fabric processed to reduce, the sinking of top line, warp tension wants control bigger than normal, to reduce warp thread Possible sinking, when knitting processed, tension weight hammer stem both sides respectively configure 5kg tension weight, the tension spring bullet of let-off mechanism Power control bigger than normal.
