Abstract
The present invention relates to a denim environmental-protection post-finishing technology, which specifically comprises that: (1) a production process comprises singeing, desizing, mercerizing, shaping before printing, PU coating, baking, shaping, shrinking, and testing packaging; (2) main technical characteristics comprise that generally the PU coating is not too thick according to the comfort degree of the handfeeling, in order to achieve good cloth surface effect, generally 2-3 rotary screens are adopted to concurrently print, the scraping cutter pressure is 9-13, and the machine speed is controlled at 30-50 m/min; (3) a single-side coating finishing process comprises singeing, desizing, mercerizing, shaping before printing, PU coating, baking, shaping, and shrinking; and (4) a denim chromatic printing production process comprises singeing, desizing, mercerizing, dyeing, drying, shaping stenting, shrinking, and finished product packaging. With the process, the enterprise can easily develop the new denim variety and use the new post-finishing process so as to create the variety suitable for market and meet the customer requirement, and the process is environmentally friendly and is worthy of promoting.
Description
Technical field
The present invention relates to a kind of denim environmental protection hindlimb unload, belong to denim technical field.
Background technology
Denim is one of clothes of extremely liking of people, denim (Denim) is also called and splits silks, that a kind of thicker look is knitted through face jean, warp thread color is dark, and be generally indigo, weft yarn is of light color, be generally the raw white yarn after light gray or kiering, also known as indigo denim, start from US West, the personnel that herd gain the name in order to make clothing; Warp thread adopts piece-dyeing one-step method dyeing, special number has 80tex (7 English prop up), 58tex (10 English prop up), 36tex (16 English prop up) etc., the special number of weft yarn has 96tex (6 English prop up), 58tex (10 English prop up), 48tex (12 English prop up) etc., adopt 3/1 tissue, also employing diversified twill is had, cowboy organized by plain weave or crape, and grey cloth is through shiinkproof finish, and washing shrinkage is less than general fabrics, quality is tight, abundant, bright in colour, weavy grain is clear; Be applicable to men and women's formula jeans, the upper dress of cowboy, cowboy vest, cowboy's skirt etc.
Summary of the invention
The object of the present invention is to provide a kind of denim environmental protection hindlimb unload, to carry out Final finishing for denim better, produce satisfactory denim.
To achieve these goals, technical scheme of the present invention is as follows:
A kind of denim environmental protection hindlimb unload, specifically comprises the following steps:
(1) technological process of production: singe → the front sizing → PU coating of destarch → mercerising → print → bake → shape → shrink → test package;
(2) main technological features: according to market to the needs of denim PU coating result and the intrinsic style keeping PU coating product, the PU coating that this department produces adopts water paste; According to the level of comfort of feel, general PU coating can not be too thick, and generally adopt 2-3 to prop up cylinder to print to reach good cloth cover effect, scraper pressure is between 9-13, and the speed of a motor vehicle controls at 30-50m/min simultaneously;
(3) effect analysis: PU top finish can give fabrics for shrinkage, the special property such as wrinkle resistant, stiffening, and the fabric feeling after PU is plentiful, there is film sense on surface; After jean warp mercerising+PU arranges, improve the shortcoming that mercerized cloth feel is too soft, stiffening not, but also remain the cloth style of mercerized cloth;
(4) one side top finish technique: singe → the front sizing → PU coating of destarch → mercerising → print → bake → shape → shrink; The processing technology of one side coating is also uncomplicated, and basic production technique is with the process of PU coating; The control of difference mainly coloured light and COLOR FASTNESS, and PU coating is produced focuses on feel; The control of coloured light is the emphasis produced, and must control the speed of a motor vehicle, scraper pressure in coating production process well, mends the uniformity that slurry will give special heed to coloured light, viscosity, the height of net cylinder entoplasm position, the size of mesh when comprising coating, and these all can have an impact to coloured light; The control criterion of COLOR FASTNESS is the standard that fades according to customer requirement, in the control of binder and temperature as the emphasis of quality control, the consumption of binder and baking temperature directly have influence on last wash water effect, so just require that the binder of mill base is consistent, the speed of a motor vehicle and drying room of printing machine, baker temperature stable;
(5) the denim chromatography technological process of production: → destarch → mercerising → dyeing → oven dry → sizing tentering → shrink → finished product packing of singing; In dyeing course, mainly be divided into following operation: dyeing, wash water, be oxidized, boil soda-wash water, oven dry: 1. dye: mixing color pigment and auxiliary agent dissolve on demand, continuous dip-dye 1-2 hour, waits fabric fibre to absorb pigment to fibrous inside, increases the COLOR FASTNESS of fabric; 2. wash water: after dyeing, because fabric upper surface posts loose colour material, need utilize machinery repeatedly to cross water flushing fabric face loose colour and remove; 3. be oxidized: utilize water and acetic acid, by the color neutralization on fabric, fix; 4. soda-wash water is boiled: by the various impurity on fabric after oxidation, utilize alkali oil (temperature: 90 DEG C) repeatedly to boil 1 hour, then wash moves hot water, is removed by the impurity on fabric totally; 5. dry: by fabric drying.
This beneficial effect of the invention is: the cowboy world is constantly in change, hand cowboy through fashion designer walks the tip at fashion forever, become seaman, denim is also along with the market demand becomes diversification, above-mentioned technique contributes to the new denim kind of enterprise development and uses new postfinishing process, releases marketable kind, meets the needs of client, and technique environmental protection, be worthy to be popularized.
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.
