The specific embodiment

Following the utility model will be by embodiment, also in conjunction with the accompanying drawings to the further concrete description of the technical solution of the utility model do.

Embodiment: the utility model as shown in Figure 1-Figure 3, it comprises the digital crepe fabric 5 with the triple latent bars of latitude, design is produced step that the triple fabrics of latitude become the latent bar digit code crape of tightness and is step 1, and the quasi-regular pattern theory generating principle that discloses according to the applicant's patent of invention 02139044.4 produces textile design flower type.Its formula is as follows: $f\left(x\right)=\frac{1}{3}\cos (u+\mathrm{<figure-callout\; id="2"\; label="v\; cos"\; filenames="Y20072030327500062.png,Y20072030327500063.png"\; state="\{\{state\}\}">v</figure-callout>}\cos \frac{2\mathrm{\&pi;j}}{q})+\frac{1}{5}(\cos u-\mathrm{<figure-callout\; id="2"\; label="v\; sin"\; filenames="Y20072030327500062.png,Y20072030327500063.png"\; state="\{\{state\}\}">v</figure-callout>}\sin \frac{2\mathrm{\&pi;j}}{q})+\frac{1}{24}\cos \frac{1}{\mathrm{uv}}+\cos \frac{1}{v}$ Can generate the figure of q=7, this figure then obtains textile design flower type through littleization processing and dichromatism processing.Step 2, carry out the plan of weave design that the triple fabrics of latitude become the latent bar digit code crape of tightness by line system CAD method, line system CAD method has obtained elaboration in foregoing invention patent 02139044.4, therefore, and the detailed method summary.Step 3, the triple fabrics of design latitude become the method for tightness.Theoretically, it is infinite many that the variation of fabric compactness is actually, because, at first from warp-wise tightness (%)=warp diameter (mm) * warp-wise density (radical/10cm) (%), broadwise tightness (%)=diameter of the weft yarn (mm) * latitudinal density (radical/10cm) can see in (%), bigger to the excursion of density through (latitude) yarn diameter (mm) with warp (latitude); Secondly, carry out tightness and change in much length (wide) degree scope, selectable excursion is very big, for example, for two kinds of tightness A, B, can be every one centimeter a kind of, also can be one centimeter A, two centimeters B, or the like; They are three years old, the various matching methods that change tightness are infinite, it still is example with above-mentioned, two kinds of tightness A, B even fixed its width separately, also have ABABAB ... ABAABABAAB ... ABBAABABBAAB ... etc. the version of various permutation and combination, and the permutation and combination of these versions on the longitude and latitude both direction, or the like.So the heavy fabric compactness of design variation will be with reference to actual needs and process conditions.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 the triple fabrics of latitude and become the latent bar digit code crepe fabric of tightness.

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 crepe fabric 5 with wrinkle reason, described weft yarn 1 has three groups, warp thread 2 has one group, these three groups of weft yarns 1 and one group of warp thread 2 interweave, and fabric 5 warp-wises are provided with the different fabric strip of tightness 3.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.A is the centre-to-centre spacing of two adjacent warps 2 among the figure, and all a equate; B is the centre-to-centre spacing of two adjacent parallels 1, and all b equate; A and b are fixed value in the utility model.

The utility model is from practicality, and the tightness that proposes concrete latitude three re-organized changes structure: 1, the triple pck counts of latitude are fixed.2, utilization is made yarn with a kind of filament fiber, be divided into single fiber yarn (single thread) with by two fibers and the yarn that closes (strand yarn).In latitude three re-organized, suppose the thigh yarn that first latitude that latitude is triple and second latitude adopt single fiber yarn or two fibers simultaneously and close, it is diverse then using single thread and its fabric compactness of yarn of these two kinds of forms of strand yarn, and in the utility model, they are relations of 1 to 2.3, conceal the bar width with the triple fabric technological parameters of concrete latitude (elementary organization, warp, weft density etc.) design as required, determine 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, promptly along on the warp direction, the variation of latitude tightness can select latitude to realize by control at warp-wise.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 the triple latent bar fabrics of latitude that corresponding warp-wise becomes tightness thus.

In the present embodiment, three groups of weft yarns and one group of warp thread interweave, and are called latitude three re-organized, and the fabric that this tissue forms is called the triple tissue fabrics of latitude, or are called for short the triple fabrics of latitude.By the overlapping number of plies of heavy latitude, traditionally uppermost one deck, promptly the ground floor latitude is called the first latitude, the one deck under it, and promptly second layer latitude is called the second latitude, by that analogy.

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

The so-called tightness that becomes refers on fabric warp-wise or broadwise, or simultaneously on the longitude and latitude both direction tightness change, weave with two or more tightness, to obtain because the special effect that the tightness variation brings.

The triple change tightnesses of so-called latitude refer to specifically that then the triple fabrics of latitude tightness on warp-wise changes, and weave with two or more tightness, conceal the bar effect to obtain because tightness changes the fabric that brings.
