CN104631125A - Environmentally friendly pretreatment technology of colored cotton - Google Patents

Abstract

The invention relates to an environmentally friendly pretreatment technology of colored cotton. The technology concretely comprises the following steps: 1, singeing, desizing, carrying out alkali boiling, mercerizing, softening, and post-treating; 2, carrying out enzyme desizing, carrying out alkali boiling, carrying out enzyme polishing, mercerizing, softening, and post-treating; 3, desizing: wherein the color of the colored cotton obtained after boiling is darker than that of a grey cloth, and the above mercerizing step greatly improves the color uniformity of the colored cotton and makes the color darker and 15-20% lighter than that of the cotton obtained after biological enzyme finishing; 4, carrying out capillary action, and carrying out enzyme desizing, wherein the capillary effect before mercerizing is 7cm/30min, the capillary effect after mercerizing is 8cm/min, the capillary effect after alkali boiling is 14cm/30min, and the softness is good; and 5, carrying out hot water washing, carrying out enzyme washing, inactivating, carrying out water washing, and airing. The colored cotton fades in the processing process, the color fading colored cotton has deep and brilliant color, and the color possibly changes. The above colored cotton production technology is environmentally friendly, allows various required colored cotton clothing clothes to be produced, and is convenient for subsequent production.

Description

Color cotton environmental protection pre-treatment process

Technical field

The present invention relates to a kind of color cotton environmental protection pre-treatment process, belong to color cotton processing technology field.

Background technology

Natural color cotton be adopt modern biotechnology cultivate a kind of when cotton boll blowing fiber just there is the fabric raw material of natural colour; Comfortable: affine skin, non-stimulated to skin, meet environmental protection and health requirement; Antistatic: because cotton fine regain is higher, not play electrostatic, not balling-up; Having a good sweat property is good: the sweat on absorption human body skin and micro-sweat, make body temperature recover rapidly normal, really reach ventilative, absorbing sweat effect; Through investigation, the environmental protection characteristic of discovery color cotton and natural colored meet the taste demand of modern's life very much, because it is without any chemical treatment, some yarn, fabric variety also remain with some cotton seed hullss, embody the sensation of its back to nature, thus product development takes full advantage of these features, accomplishes that color and luster is soft, nature, elegance, based on leisure in style, then permeate the fashion trend of this season; The embodiment of furnishings image is solemnly generous does not lose light nature again, and family spins class image and embodies warm comfortable and give the impression of returning to original purity and simplicity.

Summary of the invention

The object of the present invention is to provide a kind of color cotton environmental protection pre-treatment process, to carry out environment-friendly type pre-treatment for color cotton.

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

A kind of color cotton environmental protection pre-treatment process, specifically comprises following technological process:

(1) singe, destarch, soda boiling, mercerising, soft, post processing;

(2) enzyme desizing, soda boiling, enzyme polishing, mercerising, soft, post processing;

(3) destarch: after kiering, color is darker than grey cloth, after mercerising, color uniformity improves greatly, darkens, but more shallow than biological filtering layer 15 ~ 20%;

(4) capillary effect: first 7 centimetres/30 minutes of mercerising, after mercerising 8 centimetres/30 minutes; Enzyme desizing, after soda boiling 14 centimetres/30 minutes, after mercerising 8 centimetres/30 minutes, pliability was good;

(5) hot water wash, enzyme is washed, deactivation, and washing, dries; Color cotton work in-process can fade, but finds in producing, treated, and after fading, color cotton color is darker, more bright-coloured, but possibility variable color;

(6) pH is less than 4, color cotton lighter, and pH rises, and darken, pH is too high, fades and seriously shoals again;

(7) color cotton Color pair temperature-insensitive, pH is greater than 9, and temperature rises, and aberration strengthens; Color cotton fiber is powerful poor, often adopts coloured silk-Bai blending; Woven color cotton needs destarch;

(8) low-temperature high-alkali method: color and luster change greatly, needs to revise; The low alkaline process of high temperature: coloured effect is little, stacks and improperly easily to cut marks; Device therefor has overflow dyeing machine, dye jigger, continuous concise method.

This beneficial effect of the invention is: the cotton technique environmental protection of coloured silk of manufacture of the present invention, can produce the cotton clothing cloth of various satisfactory coloured silks, be convenient to subsequent production.

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.

Embodiment

A kind of color cotton environmental protection pre-treatment process, specifically comprises following technological process:

(1) singe, destarch, soda boiling, mercerising, soft, post processing;

(3) destarch: after kiering, color is darker than grey cloth, after mercerising, color uniformity improves greatly, darkens, but more shallow than biological filtering layer 15 ~ 20%;

(4) capillary effect: first 7 centimetres/30 minutes of mercerising, after mercerising 8 centimetres/30 minutes; Enzyme desizing, after soda boiling 14 centimetres/30 minutes, after mercerising 8 centimetres/30 minutes, pliability was good;

(5) hot water wash, enzyme is washed, deactivation, and washing, dries; Color cotton work in-process can fade, but finds in producing, treated, and after fading, color cotton color is darker, more bright-coloured, but possibility variable color;

(6) pH is less than 4, color cotton lighter, and pH rises, and darken, pH is too high, fades and seriously shoals again;

(7) color cotton Color pair temperature-insensitive, pH is greater than 9, and temperature rises, and aberration strengthens; Color cotton fiber is powerful poor, often adopts coloured silk-Bai blending; Woven color cotton needs destarch;

(8) low-temperature high-alkali method: color and luster change greatly, needs to revise; The low alkaline process of high temperature: coloured effect is little, stacks and improperly easily to cut marks; Device therefor has overflow dyeing machine, dye jigger, continuous concise method.

The above is the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications are also considered as protection scope of the present invention.
