The specific embodiment

Referring to Fig. 1, Fig. 2 and Fig. 3, it comprises that the two-layer fabric latitude becomes the latent bar digit code crape 5 of tightness, design produce step that double-deck latitude becomes the latent bar fabric of tightness into:

Step 1, the quasi-regular pattern theory generating principle that discloses according to the applicant's Chinese invention patent 02139044.4 produces textile design flower type, and its formula is as follows:

$f\left(x\right)=\frac{1}{3}\cos (u+\mathrm{<figure-callout\; id="2"\; label="v\; cos"\; filenames="Y20082017110700062.png,Y20082017110700063.png"\; state="\{\{state\}\}">v</figure-callout>}\cos \frac{2\mathrm{\&pi;j}}{q})+\frac{1}{5}(\cos u-v\sin \frac{2\mathrm{\&pi;j}}{q})+\frac{1}{24}\cos \frac{1}{\mathrm{uv}}+\cos \frac{1}{v}$

Can generate the figure of q=7, this figure then obtains textile design flower type through littleization processing and dichromatism processing.

Step 2 is by carry out the plan of weave design that the two-layer fabric latitude becomes the latent bar digit code crape of tightness by line system CAD method.Line system CAD method has obtained elaboration in patent of invention (02139044.4), therefore, detailed method slightly.

Step 3, design two-layer fabric latitude become the method for tightness.Theoretically, the variation of fabric compactness is actually infinite many.Because at first, diameter of the weft yarn (mm) is bigger with the excursion of weft density, in much length (wide) degree scope, carries out tightness and change, selectable excursion is very big, for example, for two kinds of tightness A, B, can be a kind of every one centimeter, also can be one centimeter A, two centimeters B, or the like; Secondly, the various matching methods that change tightness are infinite, still are example with above-mentioned, two kinds of tightness A, B, even fixed its width separately, ABABAB also arranged ..., ABAABABAAB ... ABBAABABBAAB ... etc. the version of various permutation and combination, and the permutation and combination of these versions, or the like.So the two-layer fabric latitude of design variation becomes tightness, be with reference to actual needs and process conditions.

Referring to Fig. 1-Fig. 3, the utility model is realized by following structure: warp thread 2 and weft yarn 1 are made of a single thread and a strand yarn, it comprises the latent bar digit code fabric 5 with wrinkle reason, described weft yarn 1 has two groups, warp thread 2 has two groups, two groups of weft yarns 1 and two groups of warp thread 2 interweave, and fabric 5 warp-wises are provided with the different fabric strip of tightness 3,4, and the tightness of adjacent strips of fabric 3,4 is alternately arranged by rule and irregular structure.The width of fabric strip 3,4 is 1-10 centimetre.

The utility model is from practicality, and the latitude tightness that proposes concrete two-layer fabric changes structure,

1, the thread count of two-layer fabric is fixed.

2, utilization is made the weft yarn of two-layer fabric with a kind of filament fiber, be divided into single fiber yarn (single thread) with by two fibers and the yarn (strand yarn) that closes.The first latitude of supposing two-layer fabric table latitude adopts the single fiber yarn, and the second latitude adopts two fibers and the thigh yarn that closes, and it is diverse then using single thread and strand its fabric compactness of yarn of these two kinds of forms of yarn, and in the utility model, they are relations of 1 to 2.

3, as required with concrete two-layer fabric technological parameter, as elementary organization, warp, weft density etc., the latent bar width of design determines to adopt the width of same tightness;

4, the width of note single thread tightness is A, and the width of note burst yarn tightness is B, then can determine a concrete A, B permutation and combination method.

5, because the utility model is based on the shuttleless loom proposition, therefore, on warp-wise (promptly along warp direction), the variation of latitude tightness can select latitude to realize by control.For example, determine that A, B are respectively on the machine one centimeter wide, and determine that concrete A, B permutation and combination method is ABAB ... then can go out one centimeter wide how many root first latitudes and second latitude are arranged according to the filling density designing and calculating, arrange whenever to inweave how many root A latitudes then and inweave how many root B latitudes again, obtain corresponding double-deck latitude thus and become the latent bar fabric of tightness.

Step 4, according to above design, the latent bar digit code crape plan of weave of the change tightness that will be obtained by line system CAD method be sent into the electronic jacquard machine management information system, carry out jacquard weaving.

According to above step, can obtain double-deck latitude and become the latent bar digit code crape of tightness.

Two-layer fabric is meant by two groups of warp thread and interweaves with two groups of weft yarns respectively, forms the fabric of overlapped upper and lower two-layer (or claiming in the table two-layer).The tissue of this fabric is called the two-layer fabric tissue, or is called for short double-layered structure.The warp on two-layer fabric upper strata and parallel are called table warp, table latitude; The warp of lower floor and parallel are called back warp, back weft.

Tightness is for density.In the unit length fabric, the filling yarn radical is called the density of fabric, and the branch through weft count is arranged.And two kinds of identical density of density differ as thickness of yarn, and its tightness degree is also different.So, must adopt an expression tightness degree index---fabric is through the tightness of broadwise.Tightness is meant the ratio of the average centre distance between filling yarn diameter and two warps, parallel, represents with percentage.That is:

Warp-wise tightness (%)=warp diameter (mm) * warp-wise density (radical/10cm) (%) ... (1)

Broadwise tightness (%)=diameter of the weft yarn (mm) * latitudinal density (radical/10cm) (%) ... (2)

Therefore, for Density, fabric compactness has reflected the isopycnic actual conditions of the geometric shape of fabric yarn more truly.

The so-called double-deck tightness that becomes, the tightness that refers on fabric warp-wise or broadwise changes, and weaves with two or more tightness, to obtain the latent bar effect that changes the two-layer fabric that brings owing to tightness.Double-deck latitude becomes the variation that tightness then specifically refers to two-layer fabric generation latitude tightness, weaves with two or more tightness, conceals the bar effect to obtain because tightness changes the fabric that brings.
