Abstract

The invention relates to a method for improving dry rubbing fastness of a smooth-haired slubbed product. The process flow of the method is as follows: getting grey cloth of the smooth-haired product, performing primary washing, milling, re-washing, dewatering, drying, decating, napping, shearing, performing wet brushing, drying, lustring, shearing, steaming and trimming, steaming and brushing, decating and getting a finished product, wherein the milling process conditions are as follows: auxiliary agents comprise 2% owf (on weight of fabric)-2.5% owf of Igephon T, 3% owf-3.5% owf of oleate soap and 0.8-1% owf of Invalon DAM dispersant; the milling time is 60-90min; and the milling temperature is 45-50 DEG C. The method mainly comprises the steps that the dispersant is added in the milling process to disperse dust and dye particles which are washed down so as to prevent the dust and the dye particles from being re-stained on fabric, enable the dust and the dye particles to be washed away in the subsequent washing process and further improve the dry rubbing fastness. According to the method, compared with normal products, the dry rubbing fastness of slubbing can be improved from level half to level1.

Description

Improve the method along woolen spinning product dry fastness

Technical field

The present invention relates to a kind of method improved along woolen spinning product dry fastness.

Background technology

Woolen fabrics comprises pure cashmere, cashmere and wool blended product, pure wool product etc., after the processing such as braying, fulling, plucking, often occurs the phenomenon that crock fastness is not up to standard, and mainly dry fastness is normal not up to standard.The reason causing dry fastness bad mainly the following aspects: 1. woolen fabrics raw material is complicated, there are many assorted hairs, lower toe feathering, secondary hair, the fine dust of some of mixing is wrapped up in these raw materials, what slubbing raw material adopted is flock dyeing, without after backwashing, therefore the dye granule of a large amount of not upper dye is had to be present in fiber surface, the dye granule of these tiny dusts is after spinning and weaving, just wrapped up in the innermost layer of fabric, in the braying, fulling process of Final finishing, be difficult to remove totally.And along wool product in the production process in rear road, again through plucking operation, after plucking, a large amount of wool fibre is pulled out by from yarn, original be like this wrapped in nexine fine dust and dye granule also taken out of, be attached to fabric face, so cause dry fastness bad.2. the dust on fabric face and dye granule, after washing, stain fabric face again, cause dry fastness bad.3. existing COLOR FASTNESS standard improves half grade than original, so originally qualified, becomes now major part defective.For this problem, we tested many braying auxiliary agents and multiple braying technique, but be all not improved.

Summary of the invention

The object of the invention is to overcome above-mentioned deficiency, a kind of method improved along woolen spinning product dry fastness is provided.

The object of the present invention is achieved like this:

Improve the method along woolen spinning product dry fastness, the technological process that the method is produced along wool product is:

Brush → decatizing → finished product is repaiied → is steamed in grey cloth → previous cleaning → fulling → after backwashing → dehydration → oven dry → decatizing → plucking → cropping → wet brush → oven dry → hot light → cropping → ripe

Milling process condition is as follows:

Auxiliary agent: Igepon T 2% (owf) ~ 2.5% (owf)

Oleate soap 3% (owf) ~ 3.5% (owf)

Dispersant (Invalon (gorgeous dimension the is even) DAM of Huntsman (Hensel steps) company): 0.8-1% (owf)

The fulling time: 60-90 minute, the concrete time is according to long contracting.

Fulling temperature: 45 ~ 50 DEG C, when being greater than 50 DEG C, gatte rwalking automatic window cools.

Fulling equipment: TURBOMAT 2C-SM/500 tetra-contracting road.

Research shows, it is best that dispersant is added in effect in fulling, because fulling effect is very violent, phase mutual friction between face, part wool fibre inside yarn also can contract out, so can take a lot of parcels dust in the yarn and dye granule out of, these dusts and dye granule can spread out rapidly by dispersant, it is allowed not again to stain on fabric, then wash through after backwashing again.And the mechanism that in previous cleaning and after backwashing operation, fabric is subject to does not have in fulling strong, the dust come out and dye granule are also few, and dispersant role is little.So we select to add dispersant in fulling process.

Compared with prior art, the invention has the beneficial effects as follows:

This method mainly adds dispersant in fulling process, the dust washed and dye granule is spread out, and allows it again not stain on fabric again, is washed off in follow-up flushing process, thus improves dry fastness.This method can improve half grade to 1 grade to slubbing dry fastness common product.

Detailed description of the invention

Embodiment 1:

Pure cashmere is dark dark blue along wool product.

This kind is produced by following technological process: brush → decatizing → finished product is repaiied → steamed in grey cloth → previous cleaning → fulling → after backwashing → dehydration → oven dry → decatizing → plucking → cropping → wet brush → oven dry → hot light → cropping → ripe;

Wherein milling process condition is as follows:

Auxiliary agent: Igepon T 2% (owf)

Oleate soap 3% (owf)

Dispersant (the Invalon DAM of Huntsman company): 0.8% (owf)

The fulling time: 70 minutes;

Fulling equipment: TURBOMAT 2C-SM/500 tetra-contracting road

Final testing result is dry fastness is 4 grades, improves 1 grade than originally, exceedes Eligibility requirements half grade.

Embodiment 2:

50% cashmere 50% wool black is along wool product.

This kind is produced by following technological process: brush → decatizing → finished product is repaiied → steamed in grey cloth → previous cleaning → fulling → after backwashing → dehydration → oven dry → decatizing → plucking → cropping → wet brush → oven dry → hot light → cropping → ripe

Wherein milling process condition is as follows:

Auxiliary agent: Igepon T 2% (owf)

Oleate soap 3.5% (owf)

Dispersant (the Invalon DAM of Huntsman company): 1.0% (owf)

The fulling time: 80 minutes

Fulling equipment: TURBOMAT 2C-SM/500 tetra-contracting road

Final testing result is dry fastness is 3.5 grades, improves half grade, reach Eligibility requirements than originally.
