Description

Gradual change stamp denim and preparation method thereof

Technical field

The present invention relates to cloth field of textiles, particularly relate to gradual change stamp denim and preparation method thereof.

Background technology

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

Chinese invention patent application CN1212172A disclosed " manufacture method with light color ice stricture of vagina denim ", it is directly on denim, use dyestuff pattern-making, then sealing wax, it is placed in the background color dyestuff of needs again and dyes, produce the pattern with light color ice stricture of vagina in this process again, make manufactured goods lovely luster, with the beautiful ice stricture of vagina pattern of light color.Disadvantageously, sealing wax process is relatively complicated and human body skin be there may be impact by wax itself.

The technological process of Chinese invention patent application CN1737233A disclosed " processing technology of colorful denim ": a. yarn dyeing, first to Quality Pure Cotton Yarn Production warping, go up sizing-dyeing machine again, Quality Pure Cotton Yarn Production is divided into the staining bath of different colours and carries out dye gigging by assorted material prescription by the ratio according to dyed yarn each needed for colorful denim pattern color, pad dyeing, each dyed yarn of ratio needed for simultaneously dying colorful denim pattern color, then starching, dry；B. weave cotton cloth；C. Final finishing；D. detect, packaging.Disadvantageously, dyeing is loaded down with trivial details, every one thread is both needed to dyeing and processes, waste material, and finished color effect is excessively bright-coloured, is completely out of the scope of denim.

Chinese invention patent application CN104068538A disclosed " a kind of warming-type fluorescent denim fabric ", it forms flannelette napped fabric layer interior, and denim is centrally located, face bed of material sandwich layer structure outside.Have drawbacks in that fluorescent fabric easily comes off.

Summary of the invention

The problem that it is an object of the invention to overcome the multifarious improvement project of colour image in prior art very imperfect, it is provided that a kind of novel gradual change stamp denim and preparation method thereof.

In order to realize this purpose, technical scheme is as follows: gradual change stamp denim, includes, the warp thread being crisscross arranged and weft yarn；Wherein, described warp thread system cotton yarn, described cotton yarn is formed stamp figure layer, described stamp figure layer is formed with again cowboy's indigo dyeing layer.

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

Step S1, it is provided that warp thread, 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 version of the manufacture method of gradual change stamp denim, in step S1, the requirement according to denim finished product of the density system of warp thread, warping axle, it is ensured that each yarn beam is parallel to each other and is closely aligned.

As the preferred version of the manufacture method of gradual change stamp denim, in step S2, the mode system direct printing of stamp or transfer printing.

As the preferred version of the manufacture method of gradual change stamp denim, in step S2, dyestuff used by stamp or pigment system adopt dyestuff or the pigment of bleach tolerant.

As the preferred version of the manufacture method of gradual change stamp denim, dyestuff in step S2 or the tone of pigment are lower than the tone with dyestuff or pigment in step S3.

As the preferred version of the manufacture method of gradual change stamp denim, in step S2, after stamp, also need instant drying.

As the preferred version of the manufacture method of gradual change stamp denim, also comprise, step S5, washing.

Compared with prior art, advantages of the present invention at least that: a kind of new denim fabric manufacture method is provided.Along with the conventional machining of the increased frequency washed or clothing factory, cloth crossfades into stamp from traditional indigo plain color, to the sensation that people is novel.

Accompanying drawing explanation

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

Detailed description of the invention

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

Referring to shown in Fig. 1, figure is the manufacture method of gradual change stamp denim.Concrete manufacture method flow process is as follows:

1) radical that warp thread requires from cylinder yarn according to the warp density of cowboy's finished product is taken yarn.Through warping axle, it is ensured that each yarn is parallel to each other and tightly around in warp beam, in order to subsequent decal.In the process of warping, warp thread to keep suitable tension force and elasticity and keep the concordance of whole warp thread.Additionally, Warp Tension Test density is wanted uniformly, smooth, it is impossible to have concavo-convex or sparse uneven phenomenon.Requiring supplementation with ground, warp thread here does not refer to single yarn, but is made up of complex root yarn entirety, is the concept in a face, rather than single line.

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

3) default design is imprinted on beamed yarn (can gamut stamp on whole warp thread, it is possible to part stamp, need selected according to design) by printing equipment.Being processed by denim conventional rinse owing to this cloth is follow-up, so the dyestuff of stamp or pigment, it is desirable to bleach tolerant (hydrogen peroxide or sodium hypochlorite), after namely being washed by bleach, decalcomania can not variable color or fade.In the present embodiment, by the problem that printed color after solving rinsing by the method for pigment printing changes.It addition, decalcomania requires that gradual change appears, so requiring the indigo that tone should dispatch from the factory lower than (secretly in) in color.During stamp, warp thread to keep uniform tension force and density, it is impossible to has up-and-down phenomenon and folded yarn phenomenon.After stamp, to immediately dry concentrator, in order to avoid there is viscous color phenomenon when returning warp beam later.

4) warp thread after stamp is indigo by sizing-dyeing machine (being also commercial equipment) the upper dye cowboy that denim is special, cowboy is indigo is completely covered decalcomania so that now cannot see or see clearly impression case.When it may be noted that dyeing starching, Warp Tension Test wants uniform ground, and tension force to keep consistent, and dividing sinker wants clear, warp thread should be avoided to exceed standard dislocation, cause that flower pattern changes.

5) gait weaving.Gait according to Warp Tension Test order, the warp beam looming weaving that will gait.This step is that cowboy walks the step making routine, seldom repeats.

6) Final finishing.The denim weaved as common denim by dispatching from the factory after the Final finishing such as shrinkproof sizing.This step is that cowboy walks the step making routine, seldom repeats.

It is seen that, though this denim is printed on design on warp thread, but the colouring of warp thread bipseudoindoxyl dye covers, therefore the denim being made into does not see there is decalcomania from the teeth outwards.Clothing or other finished product is made when this denim, after the post-treatment such as producer routine cowboy rinsing or sandblasting, again or, one integral piece cowboy's finished product increasing along with user's washing times, originally can be revealed gradually along with taking off of indigo by the indigo decalcomania covered, i.e. crossfaded into part plain color part stamp or the finished product of whole stamp by generally conventional plain color cowboy, novel and the feeling of freshness to people, increases a kind of brand-new kind more to cowboy's product.

Below only have expressed embodiments of the present invention, it describes comparatively concrete and detailed, but can not therefore be construed as limiting the scope of the patent.It should be pointed out that, for the person of ordinary skill of the art, without departing from the inventive concept of the premise, it is also possible to making some deformation and improvement, these broadly fall into protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
