Abstract
The invention provides an anti-foaming double-beam weaving process for small jacquard fabrics and relates to the field of textile technology. Different fancy warp beam warp tension and body warp beam warp tension are adopted for weaving. The total tension of fancy warp beam warps is calculated through a formula according to the shrinkage of body warp beam weave, the total mass of a body warp beam, the total tension of body warp beam warps, the shrinkage of fancy warp beam weave and the total mass of a fancy warp beam. According to the total tension of the fancy warp beam warps and the designed total number of the fancy warp beam warps, loom tension of each fancy warp beam warp is calculated.; According to the anti-foaming double-beam weaving process for the dobby, the purpose of reasonably adjusting the loom tension of the fancy warp beam weave is achieved in combination with the weight difference between the body warp beam and the fancy warp beam, so that the influence of weaving shrinkages of different types of weave is made up for. The core essence of the anti-foaming double-beam weaving process is that tension is reasonably adjusted in the warp tension control process according to requirements of shrinkages of different types of weave, the tension is adjusted continuously from a full-beam state to an empty-beam state, different amounts of warp run-in are provided for different types of weave, and the requirement of the anti-foaming process of the dobby is met.
Description
Technical field
The present invention relates to textile technology field, be specifically related to weaving technology, particularly the weaving technology field of dobby.
Background technology
Dobby is the common fabric in textiles, uses the change of two or more fabric tissue and forms the fabric of decorative pattern, be one of main Types of woven fabric, occupy sizable ratio in garment material at fabric face.Dobby because of its looming weaving technique simpler than figurative jacquard, change kind time downtime short, kind, pattern can be changed in time according to customer requirement, enterprises generally all attach great importance to dobby design produce.
Dobby can be divided into two parts on composition: shading tissue and figured texture weave.In weaving process, can according to the difference condition of two kinds of tissues, mainly the difference of two-part shrinkage carries out the selection of beam of a loom quantity.The generation of fabric shrinkage mainly comprises two aspects, shrinkage rate of weaving and arrangement shrinkage.When the shrinkage difference of two kinds of tissues is less, single loom beam can be adopted to weave.And when two kinds tissue shrinkage differences obvious time, then need adopt twin shaft weave, by different warp tensions regulate, change two kinds organize warp run-in number.
In two-beam work process, the adjustment of warp tension is very important, and often rule of thumb regulate in enterprise production process, this weaving production that can not effectively control can cause after weaving or occur foaming phenomena after arranging, have a strong impact on product quality, form the adverse consequences of the economic loss of the manufacturing enterprise that cancels the order, brings.
Summary of the invention
The object of the invention be to provide a kind of adopt the dual beams of the initiatively warp let-off carry out dobby weave time, the twin shaft that can effectively avoid fabric face to bubble weaves the anti-foaming process of dobby.
Technical scheme of the present invention is: on the dual beams loom of the active warp let-off, adopt different floral axis warp tensions and earth's axis tension force to weave, according to the shrinkage organized with weaving
η 2 , the warp thread radical organized
n 2 , the total tension force of beamed warp
f 2 and the shrinkage of flower tissue
η 1 , the warp thread radical of flower tissue
n 1 , by the total tension force of setting of following formulae discovery floral axis warp thread
f 1 :
Can according to formula obtain floral axis, total tension force of beamed warp and the warp tension of warp yarn.
The principle that the present invention is based on is: in fabric twin shaft weaving process, and the number of every latitude warp run-in is controlled by warp tension, and warp tension is larger, and every latitude warp run-in is larger.On the twin shaft weaving looms of the active warp let-off, through actual production and test, the number of every latitude dual beams warp run-in is separately directly proportional to warp tension size, and between two beams of a loom, the difference of warp run-in is directly proportional to the ratio of beam of a loom tension force and beam of a loom quality.Therefore, in the concrete two-beam work warp tension process of setting, according to the shrinkage rate of weaving difference of shading tissue and figured texture weave, every latitude warp run-in difference can be set, and then in conjunction with the warp thread radical of shading tissue and figured texture weave, reasonable set beam of a loom tension values.
The present invention, by reasonable adjusting tension force, in conjunction with beam of a loom mass discrepancy, makes up the impact of shrinkage rate of weaving between different tissues.Weaving tension is directly proportional to warp run-in to the ratio of beam of a loom quality, conjunctive tissue shrinkage difference, reasonable set Tensity size.
Therefore, the present invention is according to warp yarn supplying feature, according to shrinkage rate of weaving difference and warp thread radical, the twin shaft warp tension of the configuration active warp let-off, organized and flower tissue tension by reasonable set, make up shrinkage difference between two tissues, the foaming phenomena can effectively avoiding dobby to bring because of shrinkage difference occurs.The core essence of the method is the demand according to shrinkage between different tissues, in conjunction with the warp thread radical of two kinds of tissues, reasonable adjusting tension force in warp tension control process, and then give different tissues with different warp run-ins, the demand of the anti-foaming process of dobby is realized with this.This weaving method, for the two-beam work of the active warp let-off, can not need adjustment of tonicity in weaving process, and keeping setting, tension values is constant can obtain bubble-tight dobby.
Detailed description of the invention
Example 1: weave 144*90 small jacquard pure-cotton fabric for twin shaft, weft yarn is 45S, and warp thread is 45S single thread.Shading is organized as 2/1 twill left to right, and warp thread radical 7480 is organized on ground, and warp thread warp tension 3.4KN is organized on ground; Flower is organized as width 0.34cm, and figured texture weave is 5 piece 3 and flies Warp Satin, and flower organizes warp thread radical 1049.
Under actual contrast twill left to right is organized in this density, shrinkage rate of weaving is 8%, 5 piece 3 to fly satin weave shrinkage under this density yarn count condition is 4.6%.
Bring above each parameter into formula:
According to can be calculated, flower setting tissue warp tension is
f 1 for: 4.6%/8%*3.4*1049/7480=0.27KN.
According to the dual beams loom enterprising Row sum-equal matrix of this tension force in the active warp let-off, after machine, cloth cover is after weaving washing and arranging, and fabric face is non-foaming.
Example 2: weave 158*80 small jacquard pure-cotton fabric for twin shaft, weft yarn is 80S strand, and warp thread is 50S single thread.Be organized as plain weave, warp thread radical 5200 is organized on ground, and figured texture weave is 3/1 twill, flower organize warp thread radical 3370.Through actual contrast, plain weave shrinkage rate of weaving under this density is 12%, and twill-weave shrinkage rate of weaving under this density yarn count is 8.2%, organizes warp tension to be 3.00KN to design.
Flower setting tissue warp tension is
f 1 for: 8.2%/12%*3.0*3370/5200=1.33KN.
According to the dual beams loom enterprising Row sum-equal matrix of this tension force in the active warp let-off, after machine, whole cloth cover is after weaving washing and arranging, and fabric face is non-foaming.
