Description

The preparation method of gradual change stamp denim

Technical field

The present invention relates to the preparation method of cloth field of textiles, more particularly to gradual change stamp denim.

Background technology

Denim is that a kind of thicker thick color is knitted through face jean.Warp thread color is deep, generally indigo, and weft yarn face Color is shallow, generally the raw white yarn after light gray or kiering.Pattern is more single, lacks new meaning, more traditional.In view of this, there is dealer couple Denim has carried out many improvement projects.

" preparation method with light ice line denim " disclosed in Chinese invention patent application CN1212172A, is direct Dyestuff pattern-making is used on denim, then sealing wax, then be placed on dyeing in the background color dyestuff of needs, in this process The pattern with light ice line is produced again, makes manufactured goods lovely luster, with the beautiful ice line pattern of light color.The disadvantage is that, Sealing wax process is relatively complicated and wax might have influence to human body skin in itself.

The technological process of " manufacture craft of colorful denim " disclosed in Chinese invention patent application CN1737233A：A. contaminate Yarn, first to Quality Pure Cotton Yarn Production warping, then upper sizing-dyeing machine, the ratio of each dyed yarn will be pure according to needed for colorful denim pattern color The staining bath that cotton yarn is divided into different colours carries out dye gigging, pad dyeing, while dying colorful denim pattern by assorted material prescription Each dyed yarn of ratio needed for color, then starching, drying；B. weave cotton cloth；C. Final finishing；D. detect, pack.The disadvantage is that, dyeing Technique is cumbersome, and dyeing processing, waste material are both needed to per one thread, and finished color effect is excessively bright-coloured, is completely out of the model of denim Enclose.

" a kind of warming-type fluorescent denim fabric " disclosed in Chinese invention patent application CN104068538A, it forms suede Including layer of cloth, denim is located at centre, the sandwich layer structure of the face bed of material outside.Shortcoming is：Fluorescent fabric is easy Come off.

The content of the invention

It is an object of the invention to overcome the problem of multifarious improvement project of colour image is not very improved in the prior art, A kind of new gradual change stamp denim and preparation method thereof is provided.

In order to realize this purpose, technical scheme is as follows：Gradual change stamp denim, includes, is staggered Warp thread and weft yarn；Wherein, stamp figure layer, the stamp figure are formed with warp thread system cotton yarn, the cotton yarn Cowboy's indigo dyeing layer is formed with layer again.

Present invention also offers the preparation method of gradual change stamp denim, include following steps and perform successively,

There is provided warp thread by step S1, it is preferable that warp thread system cotton yarn；

Step S2, warp prints；

Step S3, warp dyeing；And,

Step S4, with weft weaving after gaiting.

As the preferred scheme of the preparation method of gradual change stamp denim, in step S1, the density system of warp thread is according to cowboy The requirement of cloth finished product, warping and axle, it is ensured that each yarn beam, which is parallel to each other, to be closely aligned.

As the preferred scheme of the preparation method of gradual change stamp denim, in step S2, the mode system direct printing of stamp Or transfer printing.

As the preferred scheme of the preparation method of gradual change stamp denim, in step S2, dyestuff or pigment used in stamp System uses the dyestuff or pigment of bleach tolerant.

As the preferred scheme of the preparation method of gradual change stamp denim, the tone of dyestuff or pigment in step S2 is low The tone of use dyestuff or pigment in step S3.

As the preferred scheme of the preparation method of gradual change stamp denim, in step S2, after stamp is finished, baking immediately is also needed It is dry.

As the preferred scheme of the preparation method of gradual change stamp denim, also include, step S5, wash.

Compared with prior art, advantages of the present invention at least that：A kind of new denim fabric preparation method is provided.With The increased frequency of washing or the conventional machining of clothing factory, cloth are crossfaded into stamp from traditional indigo plain color, are given people new Strange sensation.

Brief description of the drawings

Fig. 1 is the flow chart of one embodiment of the invention.

Embodiment

The present invention is described in further detail below by specific embodiment combination accompanying drawing.

Fig. 1 is referred to, shown in figure is the preparation method of gradual change stamp denim.Specific preparation method flow is such as Under：

1) radical of the warp density requirement by warp thread at cylinder yarn according to cowboy's finished product takes yarn.Through warping and axle, it is ensured that Each yarn is parallel to each other and tightly around in warp beam, in case subsequent decal.During warping, warp thread will keep appropriate Tension force and elasticity and the uniformity for keeping whole warp thread.In addition, Warp Tension Test density is uniform, it is smooth, it is impossible to have concavo-convex or dilute Dredge uneven phenomenon.Ground is required supplementation with, warp thread here does not refer to single yarn, but is integrally made up of plural one thread, is one The concept in individual face, rather than single line.

2) beamed yarn after warping is uniformly introduced into printing equipment.Printing equipment such as roller printing machine or transfer printing Machine（It is commercial equipment）.

3) default design is imprinted on beamed yarn by printing equipment（On whole warp thread can gamut stamp, Can part stamp, needed according to design selected）.Because the cloth will subsequently be processed by denim conventional rinse, so stamp is used Dyestuff or pigment, it is desirable to bleach tolerant（Hydrogen peroxide or sodium hypochlorite）, i.e., after being washed by bleaching agent, decalcomania can not become Color fades.In the present embodiment, the problem of printed color changes after rinsing is solved by using the method for pigment printing.In addition, Decalcomania requires that gradual change appears, so requiring that tone should be less than in color（It is dark in）The indigo dispatched from the factory.During stamp, warp thread Keep uniform tension force and density, it is impossible to have up-and-down phenomenon and folded yarn phenomenon.After stamp, printing paste is dried immediately Material, in order to avoid viscous color phenomenon occurs when returning warp beam later.

4）Warp thread after stamp is passed through into the special sizing-dyeing machine of denim（It is also commercial equipment）Upper dye cowboy is indigo, Cowboy is indigo to be completely covered decalcomania so that can not now see or see clearly being patterned.It may be noted that warp thread during dyeing starching Uniform ground is wanted in arrangement, and tension force will be consistent, and dividing sinker is clear, should avoid the exceeded dislocation of warp thread, cause flower pattern to change.

5）Gait weaving.Gaited according to Warp Tension Test order, by the warp beam looming weaving gaited.The step is that cowboy walks system Make conventional step, seldom repeat.

6）Final finishing.The denim weaved is as common denim by being dispatched from the factory after the Final finishings such as shrinkproof sizing. The step is that cowboy walks the step for making routine, is seldom repeated.

It is seen that, though the denim is printed on design on warp thread, warp thread bipseudoindoxyl dye colouring is covered, therefore The denim being made into does not see there is decalcomania on the surface.It is conventional through producer when this denim makes clothes or other finished products After the post-processing such as cowboy's rinsing or sandblasting, and or, one integral piece cowboy finished product increases with user's washing times, originally indigo The decalcomania covered can gradually be revealed with taking off for indigo, i.e. crossfade into portion by generally conventional plain color cowboy Divide the finished product of plain color part stamp or whole stamps, give people novel and feeling of freshness, more give cowboy's product to increase a kind of brand-new kind.

Embodiments of the present invention are only expressed above, and it describes more specific and detailed, but can not therefore understand For the limitation to patent of invention scope.It should be pointed out that for the person of ordinary skill of the art, not departing from this hair On the premise of bright design, various modifications and improvements can be made, these belong to protection scope of the present invention.Therefore, this hair The protection domain of bright patent should be determined by the appended claims.
