Abstract

The invention relates to a corduroy cloth pretreatment method. The method specifically includes the following steps of preparation, alkali rolling drying, pile cutting, hot water alkali elimination or enzyme desizing, drying, pile brushing, singeing, boiling off and bleaching, wherein in the step of alkali rolling drying, according to the concentration, alkali rolling liquor is 10-15 g/L caustic soda (100%), drying is performed after alkali rolling is performed at the temperature of 80-85 DEG C, and the moisture rate is smaller than 5%; in the step of pile cutting, a round cutter type automatic pile cutting machine is mainly used, and pile weft in fabric is cut into pile strips; in the step of desizing, a cloth body is soft after desizing, pile becomes loose, and pipe brushing is facilitated; in the step of pile brushing, pile brushing is performed on the fabric after desizing so that the pile can become loose and the pile strips can be smooth; in the step of singeing, the requirements that a pile face is regular and the pile strips are smooth and clear can be met through singeing elimination; in the step of boiling off, open-width blowing off is performed on corduroy; in the step of bleaching, chlorine bleaching is adopted in corduroy bleaching, bleaching liquor comprises 4-5 g/L effective chlorine, the concentration of the effective chlorine can be increased to 5-6 g/L for corduroy cloth high in thick strip and whiteness requirement, pH ranges from 9 to 10, after bleaching liquor rolling, the corduroy cloth is piled for 30-40 min at the room temperature, the corduroy cloth is pickled to be piled after being washed with water, and then the corduroy cloth is washed clean with water.

Description

The pre-treating method of lampwick flannelette

Technical field

The present invention relates to a kind of pre-treating method of lampwick flannelette, belong to the processing technology field of lampwick flannelette.

Background technology

CORDUROY is another large veriety in pile fabrics, of many uses, both can be used as coat fabric and interior dress material, and can be used for drapery again; CORDUROY has the plurality of specifications such as special slice, slice, discal patch, extraordinarily thick bar and jacquard weave.

Summary of the invention

The object of the present invention is to provide a kind of pre-treating method of lampwick flannelette, to produce this cloth better.

To achieve these goals, technical scheme of the present invention is as follows:

A pre-treating method for lampwick flannelette, specifically comprises the following steps:

Prepare → roll alkali oven dry → cut pile → hot water lixiviating or enzyme desizing → oven dry → brushing → → kiering → bleaching of singing;

Roll alkali to dry: object is that grey cloth itself is put down very after rolling alkali oven dry, and bar road neatly, is conducive to cut pile.Rolling concentration of lye is caustic soda (100%) 10 ~ 15g/L, dries immediately, be less than 5% containing damp rate in 80 ~ 85 DEG C after rolling alkali.

Cut pile: based on the automatic cutting machines of dise knife formula, pile filling in fabric is cut off into suede bar, for mechanical cut pile effect bad also can cut pile by hand, but work efficiency is low;

Destarch: after destarch, body is soft, fine hair is relaxed, and is conducive to brushing, and fabric washes away alkali destarch containing the few available heat level of slurry, and what textile sizing rate was high first can wash away alkali with heat level, then uses enzyme desizing, and washing is dried, and after drying, fabric is containing damp rate 10% ~ 13%;

Brushing: after destarch, fabric makes fine hair loose through brushing, suede bar is mellow and full, and after cut pile, during first open washing, matte produces along hair, later dye processing of practicing all acts in accordance with hair processing, fine hair just can be made good, and gloss foot, therefore must carry out mould turnover after every procedure terminates;

The most handy one side water suction of dehydration after open washing before brushing, in order to avoid fine hair shrivels submissive, brushing difficulty, must control fabric containing damp rate 10% ~ 13% before brushing, too low containing damp rate, fine hair is not easily loose, too high containing damp rate, dry after brushing and do not do, easily produce and crumple trace, the quality and impact is singed, brushing carries out on plate crawler belt associating brushing machine;

Singe: after bristle, wool on surface of fabric is uneven in length, the often short flannel of some curling long wool and some disorder in suede bar seam, by removing of singing, can reach that matte is neat, the mellow and full requirement clearly of suede bar, CORDUROY is singed available plate signeing or gas singeing, but it is effective with plate signeing, when using plate signeing, can not only the uneven in length disorderly fine hair of burning-off matte, simultaneously because matte contacts with scorching hot copper coin face, fine hair is burnt concordant, the effect of similar cropping, can make the finished product after processing on matte, occur soft flash of light; Main points of singing are light-burned hairs, and regulate the contact surface of matte and copper coin according to suede bar thickness, going out cloth without rolling a little, being pulled out, spray into steam smoothering by drive roll after singing;

Kiering: CORDUROY adopts open-width boilout, in kier, alkali (26 ~ 28g/L) during kiering, to be rolled be rolled into shaft-like, with caustic soda normal pressure kiering 8 ~ 10h, concentration of lye is 10 ~ 12g/L, when the decatize kiering of L-box open width, alkali concn is 30 ~ 45g/L, 100 ~ 102 DEG C of decatize lh, rolls alkali decatize continuously and can obtain better effects twice;

Bleaching: CORDUROY bleaching is general adopts chlorine drift, bleaching liquor is containing effective chlorine 4 ~ 5g/L, and thick bar and whiteness require high to be increased to 5 ~ 6g/L, pH 9 ~ 10, and roll stacking at room temperature 30 ~ 40min after bleaching liquor, after washing, pickling is banked up, then washing is clean.

This beneficial effect of the invention is: present invention process can prepare CORDUROY fabric, and technique is simple, easy to operate.

Detailed description of the invention

Below in conjunction with embodiment, the specific embodiment of the present invention is described, better to understand the present invention.
