CN102767072A - Dyeing and finishing method for long staple cotton and Lyocell bamboo fiber blended high count yarn-dyed shirt fabric - Google Patents

Abstract

The invention relates to a dyeing and finishing method for a long staple cotton and Lyocell bamboo fiber blended high count yarn-dyed shirt fabric in the production of textile dyeing and finishing. The method comprises the following steps: step 1, before weaving the fabric, conducting pre-treatment before dyeing on blended cheese and dyeing the blended cheese; and step 2, after the weaving of the fabric, carrying out pre-treatment and post-treatment on the woven fabric. The step 1 sequentially comprises the following procedures: conducting pre-treatment before dyeing, dyeing, hot water washing (80 DEG C for 10 min), acid cleaning (70 DEG C for 10 min), soaping (85 DEG C for 10 min), hot water washing, cold water washing, color fixing, softening, discharging from a vat and stoving on the cheese; and the step 2 sequentially comprises the following procedures: conducting singeing, bio-enzyme desizing, mercerizing, liquid ammonia finishing, non-ironing resin finishing on the fabric to obtain the finished product. The dyeing and finishing method has the advantages that the fabric embodies good properties of long staple cotton and Lyocell fiber; and through the pretreatment and the post-treatment, and particularly due to the utilization of resin finishing technology, the elasticity of the fabric is improved, and creasing is reduced, so that the fabric provided by the invention is a high-range fabric with favorable softness and comfortableness.

Description

The bamboo fiber blended Gao Zhise of long-staple cotton and Lyocell knits the dyeing and finishing processing method of shirt fabric

Technical field

The production dyeing and finishing manufacture field that the present invention relates to weave is meant that specifically the bamboo fiber blended Gao Zhise of a kind of long-staple cotton and Lyocell knits the dyeing and finishing processing method of shirt fabric.

Background technology

The Lyocell bamboo fibre is that the natural bamboo of employing is a raw material; With nontoxic N-methyl morpholine-N-oxide (english abbreviation NMMO) as solvent; A kind of Recycled Fibers that spinning forms under no any chemical reaction, the discharging of no waste water and gas; Having high-tenacity, high wet modulus and natural antibacterial property, is the tencel cellulose fiber that integrates natural fabric and synthetic fiber characteristic.

Long-staple cotton can combine cotton, Lyocell fiber premium properties separately with the exploitation of the bamboo fiber blended lining of Lyocell, caters to modern consumer life style and the mutually unified demand of environmental protection.Lyocell, viscose glue, cotton fiber swellbility relatively see the following form.

Can be drawn by last table data, when the wet processing chance of Lyocell fiber water was expanded, the length of fiber was almost constant, and cross-sectional direction is expanded very big, and the increase through yarn crimp when expanded causes fabric shrink, increases the thickness and the volume of fabric simultaneously.Fabric is under hygrometric state, and swelling of fiber, yarn have been crowded with the spaces that can fill in the institutional framework; If institutional framework itself is tight, therefore wet process fabric produces wrinkle, and when fabric when drying; Yarn is fixed on its reposition, and wrinkle will be fixed, and is difficult to remove.

Summary of the invention

Big for overcoming the horizontal swellbility of Lyocell described in the background technology, its fabric is easy to generate the defective of wrinkle, and the present invention has taked corresponding technical measures in cheese dyeing and fabric finishing production.

The present invention realizes through following technical measures; Comprise lining before weaving earlier to the long-staple cotton that adopted and the bamboo fiber blended cheese of Lyocell dye pre-treatment and dyeing; And fabric pretreatment and the last handling process of said lining after weaving, it is characterized in that the technological process of said cheese dyeing pre-treatment and dyeing is:

Cheese → dyeing pre-treatment → dyeing → hot water wash (80 ℃, 10 minutes) → pickling (70 ℃, 10 minutes) → (85 ℃, the 10 minutes) → hot water wash → cold wash → fixation → softness of soaping → go out cylinder → oven dry;

The prescription of said cheese pre-treatment and technology:

Said cheese dyeing prescription is:

The dyeing curve of said cheese is:

The technological process of said fabric pretreatment and last handling process is:

Fabric → singe → biology enzyme destarch → mercerising → liquid ammonia finishing → no-ironing resin arrangement → finished product;

The technological process of said biology enzyme destarch process is:

Preliminary treatment (adding penetrating agent JFC 1g/L, 70-80 ℃) → dipping biology enzyme desizing liquid → hot water wash (85 ℃ add 1-2g/LNa ₂CO ₃Deactivate processing) → cold wash → oven dry.

The prescription and the process conditions of said dipping biology enzyme desizing liquid are:

The prescription of said no-ironing resin arrangement is:

Said no-ironing resin finishing technique condition is:

Two soak two rolls (pick-up 65-70 ﹪) → oven dry (90-100 ℃) → bake (150-155 ℃, 1-2 minute).

The advantage that the present invention had is the good characteristic that fabric has embodied cotton and Lyocell fiber; And through above-mentioned pre-treatment and back arrangement; Particularly adopt the RESIN FINISH technology to improve the elasticity of fabric, reduced the wrinkle phenomenon, fabric is become has the high-grade fabric of improved flexibility and comfortableness.
