Abstract

The present invention relates to superfine fiber cut velvet fabric and its woven process. During the weaving, composite superfine Dacron-Chinlon filament as material is processed into composite superfine Dacron-Chinlon velvet through steaming to dry, weaving, cutting, pre-settling, opening, settling, dyeing, antistatic treatment, settling and circling. The composite superfine Dacron-Chinlon velvet has good hand feeling, good look and high heat insulting performance, and may be used in producing various high-grade household articles and as material for high-grade costume.

Description

Composite ultrafine fiber VELVET and spinning technique thereof

Technical field the present invention relates to superfine fibre clipping cloth field, relates to the spinning technique of this flannelette simultaneously.

Technical background is made velvet material now, generally is the grey cloth that the chemical-fibres filaments with cotton yarn, TC yarn or common fiber number directly is made into, through cut circle, dyeing and finishing forms.This velvet performance vague generalization, its warmth retention property is poor, and comfort level is poor, and cotton easily falls hair, and the feel of long filament is coarse, can not adapt to the requirement of spinning high-grade fabric articles and warming, comfortable clothes.

It is material with the bright and beautiful composite superfine long filament of washing of making the wedge fiber that colyliform alternately arranges mutually that summary of the invention the object of the present invention is to provide a kind of, dry through steaming oven dry, by being made into flannelette through volume and weft knitting, again through clipping, pre-setting is opened fine dyeing, antistatic treatment, typing, the velvet spinning technique of composite ultrafine fiber of looping and forming.

The present invention includes the bright and beautiful composite superfine long filament of washing of sliver type, the described brocade of washing is terylene and polyamide fibre, and terylene wherein and polyamide fibre are the wedge fiber, and its distribution is made colyliform and alternately arranged mutually, and the long filament of opening two kinds of heterogeneities of fine back terylene and polyamide fibre repels mutually; Described wedge fiber does have PA-6 to support as the core shape during colyliform arranges mutually, makes the PET wedge fibre number as single fiber be less than 0.2dtex.

The velvet spinning technique of above-mentioned composite ultrafine fiber can be: earlier that the bright and beautiful composite superfine long filament of washing of sliver type bobbin steaming oven dry is dry, then on volume and weft-knitted towel machine, be made into blank, with loop cutting machine the looped pile on the blank is cut, carry out pre-setting, dyed again machine decrement is opened fine dyeing, add antistatic auxiliary agent and carry out antistatic treatment, looping through typing forms the suede material and then must become brilliant again, and its technological process is: yarn steaming-weave-cut circle-pre-setting-decrement is opened fibre dyeing-antistatic treatment-finalize the design-loop-finished product.

Described steaming baking can be steamed 1.5 hours in the yarn steaming device, vacuumized dry 0.5 hour.

The present invention adopts washs bright and beautiful composite superfine long filament cross section to make the wedge colyliform arranged evenly mutually, and there is the support of core shape at its center; Dry before knitting through steaming oven dry, make its boiling water shrinkage less than 1%, curling stability reaches more than 90%; Can make and produce crystalline substance to have velvet good, soft plentiful, the comfortable pine of sense of touch is sliding, and drapability is good, and heat-insulating property is strong, and machine washing and hand washing be the good result of fulling milling not all.

Description of drawings Fig. 1 makes wedge colyliform structure arranged schematic cross-sectional view alternately mutually for the terylene that constitutes flannelette and polyamide fibre superfine fibre.

Fig. 2 makes fiber make the core shape supporting plane schematic diagram that colyliform is alternately arranged mutually.

The specific embodiment now is illustrated in conjunction with the accompanying drawings and embodiments.

Press Fig. 1, Fig. 2, terylene 1 and polyamide fibre 2 superfine fibres by the sliver type are the wedge fiber, distribute on its cross section and do colyliform alternately arrangement mutually, opening fine back terylene 1 does to repel mutually with two kinds of heterogeneities of polyamide fibre 2, the wedge fiber do colyliform arranged evenly in, there is PA-6 to support 3, makes fiber number be less than 0.2dtex as the PET wedge fiber of single fiber as the core shape.

When spinning above-mentioned composite ultrafine fiber VELVET, be 167dtex/70 * 16F with specification earlier, being about to be equivalent to 70 * 16 superfine fibre bobbins for a branch of yarn places the yarn steaming device through knitting preceding 1.5 hours saturated vapor yarn steamings, and in the yarn steaming device, vacuumized dry 0.5 hour, make its boiling water shrinkage less than 1%, curling stability reaches more than 90%; Be made into the single or double blank on warp let-off volume and the weft-knitted towel machine then, the terry height that is made into is 2.8mm, send and wipes out looped pile on the shearing machine, and the suede after looped pile is wiped out is thick to be 2.2mm, just becomes smooth clipping cloth; Carry out pre-setting again, dyed machine carries out decrement and opens fine dyeing, adds antistatic auxiliary agent etc. and carries out antistatic treatment, oven dry, typing, it is good then to get velvet after looping, the gloss top grade, sense of touch is comfortable, pine is sliding, and drapability is good, and is extremely efficient in preserving heat, and machine washing and hand washing be the composite ultrafine fiber velvet of fulling milling not all.

Claims
