Abstract

The invention relaters to a blend fabric dyeing process, in particular a knitted sport wool fabric and a dyeing and finishing process thereof. The fabric is made from Australia Meilinuo superfine mercerized wool and functional polyester fibers. The process comprises the steps of dyeing, finalizing, reduction clearing, drying and finalization, wherein the dyeing process is an activity-dispersion dye-bath dyeing process and comprises the addition of a protective agent GN. The process has good dyeing effect, and effectively reduces the damaged wool, ensures the dyeing color fastness of two fibers and improves the color fastness of the improved dyeing to 3 to 4 grade due to the adoption of the environmental-friendly dye and the protective agent; and the process realizes short production period, less energy consumption and low production cost due to the adopted activity-dispersion dye-bath dyeing process.

Description

Knitted sport wool fabric and dyeing and finishing technology thereof

Technical field

The present invention relates to a kind of blended fabric dyeing technology, especially a kind of knitted sport wool fabric and dyeing and finishing technology thereof.

Background technology

Two kinds of fiber co-bathing dyeings will reach desirable Color and color and luster, dyestuff, auxiliary agent, process conditions that is used for two kinds of stock-dyes etc. should do not conflicted mutually, should not have tangible adverse effect each other, dyefastness, vividness, coloured light that dyes product etc. must conform to quality requirements.Just there are some problems as wool fibre and functional fiber co-bathing dyeing.Wool fibre is issued to desirable Color at 98 ℃ dyeing temperature, obtain the correct color of needs, and functional fiber will reach desirable Color and color and luster, dyeing temperature need reach 125 ℃～130 ℃, under this high-temperature and high-pressure conditions, wool fibre has very macrolesion, can lose some functions that wool fibre itself is had.Adopt the method for carrier dyeing to be implemented in 98 ℃ dyeing temperature dyeing down as functional fiber, wool fibre can obtain needed color and luster with functional fiber under identical dyeing temperature; But the carrier auxiliary agent contains toxic and carcinogenic, is non-environmental protection auxiliary agent.Adopt the COLOR FASTNESS of carrier dyeing poststaining poor, dark colour generally can only reach about 2 grades.

Therefore traditional lining can't resolve the difficult problem of two kinds of fiber co-bathing dyeings, look is knitted and is formed after all adopting elder generation that two kinds of fibers are dyeed respectively, but also there are the following problems for this method: powerful decline after the stock-dye, can cause difficulty of weaving to strengthen behind the spun yarn, broken end is many, the lining flaw is many, and cloth cover is easy to generate horizontal stripe, and product quality is low.And the small lot setting-out is long with the production in enormous quantities required time, and speed to respond to the market is slow, does not satisfy client's delivery date.Adopt look weaving process flow process also long, energy resource consumption is big, the cost height.

Ordinary movement clothes mostly are cotton and polyster fibre is made, and the sportswear dress of cotton system is comfortable, by certain moisture, but discharge the moisture content ability, moisture content is many can suction on one's body, also can feel under the weather; Washing back modification is big, easily produces wrinkle, wears also not attractive in appearance; Washing fastness is poor, and light fastness is poor, and perspiration fastness is poor, and many local colors of perspiring when the whole clothes in washing back worn can be taken off a lot, and the different parts color and luster of whole clothes differs greatly, and is very not attractive in appearance; The sportswear hygroscopicity of terylene system is poor, discharges the moisture content ability, and after a large amount of perspirations of motion, on one's body clothes can be bonded at, human body sensory like a hen on a hot girdle.

Summary of the invention

The technical problem to be solved in the present invention is: in order to overcome above-mentioned defective, the invention provides a kind of knitted sport wool fabric and dyeing and finishing technology thereof, it can make two kinds of fiber co-bathing dyeings, and Color is good, with short production cycle, less energy consumption, and production cost is low.

The technical solution adopted for the present invention to solve the technical problems is: a kind of knitted sport wool fabric, lining composition are beautiful promise superfine mercerization wool in Australia and functional polyalkylene ester fiber.

Described functional polyalkylene ester fiber can be hydroscopic sweat-eliminating polyester fiber or high-elastic polyester fiber of T400 or PTT formative memory fiber.

The knitted sport wool fabric dyeing and finishing technology has following technical process: be followed successively by dyeing, and typing, reduction is washed and drying and shaping, and dyeing process adopts activity-DISPERSE DYES one-bath dyeing technology, and adds protective agent GN.

In dyeing process, the dye vat entry adds wool REACTIVE DYES and functional polyester fiber dispersion dyestuff; add protective agent GN again, be lowered at 60 ℃ and dye, be warming up to 110-120 ℃ then gradually; be incubated 40-60 minute, then cool to gradually below 60 ℃ to clean and go out cylinder 3-4 time.

In shaping process, required setting temperature is 170-180 ℃, in this temperature range dyestuff is fully distilled, and is convenient to improve in the subsequent handling dyeing COLOR FASTNESS.

Wash in the operation in reduction, add the faintly acid reductant down for 80 ℃, clean each 15 minutes 2 times in water temperature.

In the drying and shaping operation, required temperature is 120 ℃, to guarantee the COLOR FASTNESS that dyes.

The invention has the beneficial effects as follows: this technology Color is good, adopts the dyestuff and the protective agent of environmental protection, and it is impaired effectively to reduce wool, guarantees the dyeing COLOR FASTNESS of two kinds of fibers, improves the back COLOR FASTNESS and can reach 3～4 grades; Adopt activity-DISPERSE DYES one-bath dyeing technology, with short production cycle, less energy consumption, production cost is low; This sport wool fabric dress comfortable, bright in colour, clothing well-pressed not modification, hygroscopicity and good permeability.

The specific embodiment

Embodiment: select 180g/m for use ², door width of cloth 160cm knitted sport wool fabric, lining composition: 75% hydroscopic sweat-eliminating polyester fiber, 25% superfine mercerization wool, wool is that Australia is produced beautiful promise superfine wool and made after stripping squama mercerising is handled, and keeps moisture absorbing and sweat releasing that wool fibre itself had, function such as ventilative, warming.The dyestuff composition: lucky magnificent DISPERSE DYES: the S-R that accounts for lining weight 1.5% is bright red, accounts for the 5BL carbuncle of lining weight 0.5%; Restrain firm plain wool REACTIVE DYES: the B-CFE that accounts for lining weight 1% is bright red.

Dyeing process: dye vat entry; add firm plain wool REACTIVE DYES of gram and Ji Hua DISPERSE DYES; the wool protective agent GN that adds lining weight 3% again; this protective agent makes wool injury-free when high temperature; be lowered at 60 ℃ and dye; speed with 1 ℃/min is warming up to 110-120 ℃ gradually then, is incubated 40-60 minute, then cools to clean below 60 ℃ with the speed of 1 ℃/min to go out cylinder 3-4 time.Described wool protective agent is available from closing auspicious chemical industry Co., Ltd in Hangzhou, model is SP-OLS.

Typing: setting temperature is 180 ℃, and the speed of a motor vehicle is 15 yards/minute, under this temperature dyestuff is fully distilled, and is convenient to improve in the subsequent handling dyeing COLOR FASTNESS.

Reduction is washed: at 80 ℃ of faintly acid reductants that add lining weight 3% down of water temperature, clean each 15 minutes 2 times.This reductant is available from Zhejiang Hongda Chemicals Co., Ltd., and model is D-168A.

Drying and shaping: setting temperature is 120 ℃, and 20 yards/minute of the speed of a motor vehicle are to guarantee the COLOR FASTNESS that dyes.
