Abstract

The invention discloses a method for producing other-color all-cotton colorful bar clothes, wherein, weaving cation modified cotton yarn, cation bleached AB yarn and common white cotton yarn into white bar clothes; using active dye to dye the white bar clothes via two-step method in one bath or two bath, while the active dye is common active dye or the active dye with low affinity on cotton fiber. The inventive white bar clothes can be dyed into needed color, applicable to the production with low batch and multiply kinds.

Description

The preparation method of novel pure cotton color stripe

One, technical field

The present invention relates to a kind of preparation method of heterochromatic accent pure cotton color stripe, more particularly, be that cation-modified cotton yarn, cationic bleach AB yarn and common white cotton yarn are made into white stripe, the application of active dyestuff carries out the method for two-step method dyeing to white stripe.

Two, background technology

In the prior art, in general, cotton yarn dyeing earlier can be got heterochromatic accent pure cotton color stripe for different target tones through making up mutual braiding.And traditional fancy AB yarn then earlier with cotton dyeing, adopts the rove of two different color and lusters to feed the spinning-drafting device simultaneously again and is spun into the double-colored yarn of AB.This kind stripe is long delivery date, needs the pure color yarn and the fancy AB yarn stock of a large amount of kinds.

In order to address this is that, can earlier cation-modified cotton yarn and common white cotton yarn be made into white stripe, the application of active dyestuff dyes to stripe again, and the color stripe that dyes is matching in color, depth striped is obvious, but its shortcoming is to show two kinds of tones that differ greatly.Therefore, for showing the style of heterochromatic system, heterochromatic accent, whitening method is stayed in the dyeing that needs to use bicomponent fiber.

Three, summary of the invention

One of purpose of the present invention provides a kind of preparation method of heterochromatic accent pure cotton color stripe.

Two of purpose of the present invention provides and a kind of cation-modified cotton yarn, cationic bleach AB yarn and common white cotton yarn is made into white stripe, and the application of active dyestuff carries out the method for two-step method dyeing to white stripe.

These and other purpose of the present invention will further embody and set forth by following detailed description and explanation.

In the preparation method of heterochromatic accent pure cotton color stripe of the present invention, cation-modified cotton yarn, cationic bleach AB yarn and common white cotton yarn are made into white stripe, the application of active dyestuff carries out two-step method dyeing to white stripe, described dyeing is one bath two stage process or two one bath two-step methods, and described REACTIVE DYES is common REACTIVE DYES or the REACTIVE DYES low to cotton fiber affinity.

Further, in the preparation method of heterochromatic accent pure cotton color stripe of the present invention, in dyeing product, bar is cation-modified cotton yarn between dark color, and fancy AB yarn style is a cationic bleach AB yarn, and bar is common combing bleached yarn between light color.The non-same colour system of the color of bar between the depth is two tones that differ greatly, and fancy AB yarn style is the mixed color effect of two kinds of tones.Wherein cationic bleach AB yarn adopts 50% market bleach cotton and 50% cation-modified cotton, makes with the AB spinning process.In dyeing, do not add saline and alkalinely, or only add alkali not with salt.Described REACTIVE DYES is vapour crust CIBACRON S or De Sida Procion PX REACTIVE DYES.

In the present invention, the preparation method of cation-modified cotton yarn gets 100% cation-modified cotton spinning, and wherein the preparation method of cation-modified cotton is earlier bulk cotton fibres to be re-used cation modifier to handle after concise pre-treatment.(seeing Chinese patent CN200510063111.8 for details, the method for making pure cotton yarn of no flying contamination)

In the present invention, the preparation method of cationic bleach AB yarn is with 50% market bleach cotton and 50% cation-modified cotton, processes with the AB spinning process.Wherein the preparation method of cation-modified cotton is earlier bulk cotton fibres to be re-used cation modifier to handle after concise pre-treatment.(seeing Chinese patent CN200510063111.8 for details, the method for making pure cotton yarn of no flying contamination)

White for guaranteeing that the common white cotton yarn stays when the dyeing, avoid staining as far as possible, can select for use the cotton affinity height of modification, the dyeing very little, for example the Procion PX REACTIVE DYES of De Sida cotton fiber affinity; And rationally formulate dyeing condition, and guarantee that as far as possible the modification cotton exhausts the maximum of dyestuff, reduce and stay white fiber staining amount, for example in dyeing, do not add saline and alkalinely, or only add alkali not with salt.Therefore in the fiber " dyeing is stayed white ", have only the modification cotton-wadded quilt to dye a certain tone, and not staining of common cotton or slight staining; If adopt and high REACTIVE DYES and the normal dyeing technology of cotton fiber compatibility, then modification cotton and common Cottonopolis dye the same tone for depth style, and wherein the cotton dye uptake of modification is than the common cotton height.

The two-step method dyeing of different tone dyestuffs is promptly used in the rationalization combination of " dyeing is stayed white " and " normal dyeing ", comprises one bath two stage process and two one bath two-step methods, and the pure cotton color stripe after guaranteeing to dye represents the mannerism of heterochromatic accent.

Can dye required color at any time with the white stripe that method of the present invention is made, effectively reduce plant stock, shorten product and handed over the phase, be applicable to small lot, many variety production.The color stripe that uses the inventive method to produce is matching in color, and heterochromatic depth striped is obvious, can be the excellent raw material of producing high-grade underwear, T-shirt, Casual Wear etc.

The preparation method of the heterochromatic accent pure cotton color stripe of the inventive method is equally applicable to pure cotton color stripes or pure cotton color plaids etc.

Below further specify the present invention by specific embodiment, but embodiment only be used for the explanation, can not limit the scope of the invention.

In the present invention, if not refer in particular to, all parts, amount are the unit of weight based on gross weight, and all raw materials all can be buied from market.
