Abstract

The invention relates to a fabric dyeing process, in particular to a knitted sportwool fabric and a dyeing and finishing process thereof. The fabric comprises the components including Australian merino superfine mercerized wool and functional polyester fibers. The dyeing and finishing process comprises the steps of dyeing, setting, reduction clearing and hot setting in sequence, wherein in the dyeing step, the one-bath dyeing process based on the reactive-disperse dyes is adopted, and a protecting agent GN is added. The process has a good dyeing effect; the environment-friendly dyes and protecting agent are adopted, thus effectively reducing wool damage and ensuring the dyeing color fastness of the two fibers; the color fastness after improvement can reach grade 3-4; and the one-bath dyeing process based on the reactive-disperse dyes is adopted, thereby ensuring that the production period is short, the energy consumption is low and the production cost is low.

Description

Knitted sport wool fabric

The application is that original applying number is 200910033985.7 divides an application, and original application day is on May 27th, 2009, and the original application name is called knitted sport wool fabric and dyeing and finishing technology thereof.

Technical field

The present invention relates to a kind of fabric dyeing process, especially a kind of knitted sport wool fabric.

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, and the wool injury tolerance reaches 20% during co-bathing dyeing, 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, 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, described sport wool fabric adopt beautiful promise superfine mercerization wool in Australia and functional polyester fiber interweaving to form.

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

At the dyeing and finishing technology that described knitted sport wool fabric carries out dyeing and finishing, have following technical process: be followed successively by dyeing, 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 fabric structure that adopts beautiful promise superfine mercerization wool in Australia and functional polyester fiber interweaving to form makes the injury tolerance of wool when lining can reduce High Temperature High Pressure when carrying out co-bathing dyeing, and the wool injury tolerance is reduced to 1～3%, and Color is better simultaneously.

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.
