Abstract

The invention discloses deep color easily-dyed thick-stitch single-side velvet and a production method of the deep color easily-dyed thick-stitch single-side velvet. The thick-stitch single-side velvet comprises superficial silks and bottom silks, wherein the superficial silks are knitted by 900D/768F polyester fibers obtained by twisting 30% of general polyester fibers and 70% of cationic modified polyester fibers in a texturing process; the bottom silks are knitted by 150D/48F polyester fibers; the superficial silks and the bottom silks are serially sleeved in sequence, and the thick-stitch single-side velvet with rough style and soft and comfortable feeling is obtained by dyeing, drying and after-finishing knitted gray fabric. The general polyester fibers and the cationic modified polyester fibers are directly twisted in the texturing process, in the knitting process, horizontal stripes caused by uneven networks do not appear after the cationic polyester fibers and the general polyester fibers are combined, a plurality of the cationic modified polyester fibers are utilized by the superficial silks, so that the groups with good affinity with dispersible cationic dye are increased, the fabric is unlikely to decolor and can be dyed only at room temperature, and the color and lustre of the fabric is enriched.

Description

A kind of dark bodkin single-side pile and production method thereof of easily dying

Technical field

The present invention relates to a kind of dark bodkin single-side pile and production method thereof of easily dying, belong to textile technology field.

Background technology

Polyster fibre is hydrophobic synthetic fiber, shortage can with the functional group of the combinations such as direct dyes, ACID DYES, basic-dyeable fibre.Although have the ester group that can form with DISPERSE DYES hydrogen bond, the terylene molecular chain structure is tight, dye molecule is difficult for entering fibrous inside, cause the dyeing difficulty, color and luster is dull, generally can not adopt dark color to dye, and directly has influence on the exploitation of polyester fabric designs and varieties.Because the degree of crystallinity of terylene is high, only there is less space in the fiber, when temperature is low, the amplitude that molecular thermalmotion changes its position is less, under wet condition, polyster fibre can increase the space by violent swelling as cotton fiber again, and dye molecule is difficult to be penetrated into fibrous inside.Usually can only dye with DISPERSE DYES during dyeing terylene, and must under High Temperature High Pressure or by carrier, dye.

Summary of the invention

The present invention provides a kind of dark bodkin single-side pile that easily dyes in order to address the above problem.

The present invention is for realizing this purpose, the method that adopts is: a kind ofly easily dye dark bodkin single-side pile, comprise face silk and end silk, by face silk and end silk go here and there successively the cover after carry out post processing, described silk raw material is the terylene of 900D/768F, and the raw material of silk of the described end is the terylene of 150D/48F, and the terylene of described 900D/768F is the terylene that mixes that comprises ordinary polyester and Cationic Dyeable Pet, wherein ordinary polyester accounts for 30%, and Cationic Dyeable Pet accounts for 70%.

A kind of production method of easily dying dark bodkin single-side pile, described production stage is as follows:

Ordinary polyester is added bullet through elasticizer, add Cationic Dyeable Pet in the texturing process and carry out the terylene that twisted forms 900D/768F, wherein ordinary polyester accounts for 30%, Cationic Dyeable Pet accounts for 70%, the terylene woven of 900D/768F is become the face silk, the terylene woven of 150D/48F becomes end silk, and face silk and end silk are gone here and there cover successively;

The grey cloth that makes is dyeed, dyeing comprises dip-dye, reduction cleaning and neutralization washing, contaminate the dyestuff that adopts and comprise the dispersible cationic dyestuff, adjuvant used glacial acetic acid 0.8g/L, high temperature levelling agent 1.2g/L and the sodium acetate 0.5g/L of comprising, dye bath is than being 1:10～12, the pH value is 4.5, dyeing temperature is 130 ℃, is incubated 30～40 minutes, and reduction cleaning auxiliary agent is sodium hydrosulfite 1～2g/L and caustic soda 2～3g/L; bath raio is 1:10～12; temperature is 80 ℃, in and water washing assistant and water be glacial acetic acid 1g/L, bath raio is 1:10～12; temperature is 60 ℃, cleans 15 minutes;

At 130 ℃, cloth speed is for drying under the 20m/min with the grey cloth after cleaning;

Grey cloth is carried out rear arrangement and typing.

Its beneficial effect is: in texturing process directly with ordinary polyester and Cationic Dyeable Pet twisted, just can not occur because CATION terylene and the irregular horizontal stripe that causes of the compound rear network of ordinary polyester in the braiding process, adopt simultaneously bodkin rough apart from the knitted or woven fabrics style, soft comfortable; The face silk uses Cationic Dyeable Pet in a large number, has increased and the good group of dispersible cationic dyestuff compatibility, makes fabric be difficult for decolouring, only needs just can dye at normal temperatures, has enriched the color and luster of fabric.

The specific embodiment

Disclosed all features in this specification, or the step in disclosed all methods or the process except mutually exclusive feature and/or step, all can make up by any way.

Disclosed arbitrary feature in this specification (comprising any accessory claim, summary) is unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, unless special narration, each feature is an example in a series of equivalences or the similar characteristics.

The color and luster of horn of plenty fabric makes the facing material design and colour diversification of varieties, the present invention proposes a kind of production method of easily dying dark bodkin single-side pile, describedly easily dyes dark bodkin single-side pile and makes by face silk and end silk string cover and through later arrangement and form.Ordinary polyester is added bullet through elasticizer, add Cationic Dyeable Pet in the texturing process and carry out the terylene that twisted forms 900D/768F, wherein ordinary polyester accounts for 30%, and Cationic Dyeable Pet accounts for 70%.The terylene woven of 900D/768F is become the face silk, and the terylene woven of 150D/48F becomes end silk, and face silk and end silk are gone here and there cover successively, and the fabric that obtains so can be owing to network be not inhomogeneous, and causes the appearance of band, influence surface item matter.

The grey cloth that makes is dyeed, dyeing comprises dip-dye, reduction cleaning and neutralization washing, contaminate the dyestuff that adopts and comprise the dispersible cationic dyestuff, the adjuvant used glacial acetic acid 0.8g/L that comprises, high temperature levelling agent 1.2g/L and sodium acetate 0.5g/L, dye bath is than being 1:10, the pH value is 4.5, dyeing temperature is 130 ℃, is incubated 30 minutes, and reduction cleaning auxiliary agent is sodium hydrosulfite 1g/L and caustic soda 2g/L; bath raio is 1:10; temperature is 80 ℃, in and water washing assistant and water be glacial acetic acid 1g/L, bath raio is 1:10; temperature is 60 ℃; cleaned 15 minutes, the grey cloth after the cleaning is at 130 ℃, cloth speed is dried under the 20m/min; can make color on the fabric dyeing; owing to adopted 70% CATION terylene, increased the group good with dispersible cationic dyestuff compatibility, dyestuff adheres to and is more prone to; be easier to catch the dyestuff of dark color than ordinary polyester fabric or the less fabric of Cationic Dyeable Pet, enriches the color pattern of fabric.

Grey cloth is carried out rear arrangement and typing, and rear arrangement comprises plucking, bristle, cropping and shakes grain, and after later arrangement, the fabric soft fluffy is comfortable, and pattern is rough.

The present invention is not limited to the aforesaid specific embodiment.The present invention expands to any new feature or any new combination that discloses in this manual, and the arbitrary new method that discloses or step or any new combination of process.
