Description
Technical field
The present invention relates to a kind of dye selection at bamboo charcoal modified polyester fibre dyeing, and in slub dyeing dye corresponding dyeing, aftertreatment technology of complex dye.Belong to the stock-dye technical field.
Background technology
In the epoch that modern science and technology is advanced by leaps and bounds, science and technology brings increasing benefit for people's life, and people go out toward the health of back to nature and comfortable more, and many new fibers also just arise at the historic moment, and the bamboo carbon dacron fiber of Chu Xianing is exactly one of them in recent years.
Bamboo charcoal modified polyester fibre is meant that bamboo charcoal ultramicro powder and polyester are had a multi-cellular structure by what co-blended spinning was made, has the polyster fibre of specific functions such as superpower absorption, antistatic, antibiotic, mildew-resistant, transmitting anion.Its production process is: the bamboo of perennation is formed bamboo charcoal by 1000 ℃ of anaerobic high-temperature firings; Methods such as employing air-flow pulverizing are broken into ultramicro powder with bamboo charcoal powder; The bamboo charcoal ultramicro powder that crushes is evenly dispersed in the polyester support, is processed into the bamboo charcoal dacron master grain of high-load, wherein bamboo charcoal content is about 40%; Then, in terylene chips, add different proportion bamboo charcoal dacron master grain, obtain the bamboo charcoal terylene through spinning technique according to the difference requirement of product.Bamboo charcoal content is generally about 3% in the bamboo charcoal terylene, the highlyest is no more than 7%.
In the dyeing of terylene, terylene belongs to hydrophobic fibre, fibre structure is tightr, the amorphous region that dyestuff must enter fiber during dyeing could combine with fiber, and DISPERSE DYES has affinity to hydrophobic fibre, and in these fibers, have dissolubility, so in normal dyeing, use DISPERSE DYES at high temperature to dyeing terylene.Cation dyes are class synthetic dyestuffs of producing the earliest, be mainly used in the dyeing of polyacrylonitrile fibre, because cation dyes have positive charge, so during with anionic dyestuff and promoter effect, generate precipitation or oily mater, for fear of this phenomenon, make them temporarily be transformed into neutral charge with suitable anionic auxiliary some cation dyes and make the dyestuff of high degree of dispersion, be called disperse type cationic dye, dye in the process last, they can be heated and dissociate gradually, disengage on the original cation dyes and dye fiber.
Bamboo carbon dacron fiber is compared with conventional polyester, physical property and chemical property are all different, added hydrophilic anionic group in the molecular structure of bamboo carbon dacron fiber, but not sulfonic acid group, DISPERSE DYES reduces the affinity of bamboo carbon dacron fiber like this, dissolubility in fiber also reduces, and also weakens with the conjugation of fiber, again because the adding of bamboo charcoal powder thereupon, increased the hole of fiber, fiber is cellular hollow structure, combines weak dyestuff with fiber and comes out easily, so after dyeing with DISPERSE DYES, COLOR FASTNESS is very poor, through reduction cleaning, then most dyestuff can't be reached the color requirement by wash-out at all.
Because bamboo carbon dacron fiber is cellular hollow structure, dyestuff is easy to enter fiber, so we consider to select the dyestuff of other types to its dyestuff.
Summary of the invention
The objective of the invention is to select a kind of suitable bamboo charcoal modified polyester fibre slub dyeing, Color is good, COLOR FASTNESS is good and in dyeing course, copper ammonia fibre is damaged little dye well dyeing.
The object of the present invention is achieved like this: a kind of dyeing of bamboo charcoal modified polyester fibre is characterized in that it is to adopt disperse type cationic dye dyeing.
The dyeing of copper ammonia fibre of the present invention, described disperse type cationic dye adopt the A Si that is produced by German De Sida textile dyestuff company (Dystar) to bend and draw high (Astrazon) disperse type cationic dye.
Because it is electronegative to have anionic group in the molecular structure of bamboo carbon dacron fiber, cation dyes are then positively charged in dye bath, therefore cation dyes combine with the anion of bamboo charcoal terylene easily, consider that cationic migration property can be relatively poor, in order to improve level-dyeing property, select disperse type cationic dye that bamboo carbon dacron fiber is dyeed.
Because the structure and the common acrylic fibers of bamboo carbon dacron fiber are different, though also be to adopt cation dyes to dye but technology must be reformulated, property and structure according to bamboo carbon dacron fiber is determined process conditions, and technology is divided into two parts: dyeing and post processing.
The first step, dyeing
The bamboo charcoal modified polyester fibre wool top pinecone is placed in the high temperature top dyeing machine, at 30-40 ℃ of operation 3-5min, add 0.3-0.5g/L glacial acetic acid and 2.5-4g/L glauber salt, operation 5-10min, add dyestuff, begin to heat up behind the operation 5-10min, heating rate 1-2 ℃/min, when reaching 80 ℃ ± 2 ℃, temperature stops heating and heat preservation 10-15min, speed with 0.75-1 ℃/min is warming up to 100-115 ℃ again, operation 40-60min (determining the length of temperature retention time by the depth of color), directly discharge opeing flushing, bath raio 1: 20-50.
In bamboo carbon dacron fiber, because the adding of powdered carbon, increased the hole in the fiber, and be micropore more than 90% in the pore structure, for the active carbon polyester staple fiber provides a large amount of internal surface areas, and a large amount of micropores all opening at fiber surface, dye on dyestuff in the process, the approach of dye molecule adsorption and permeation is short, can directly enter fibrous inside, this makes the dyeing condition that needs reduce, adding bamboo carbon dacron fiber is that bamboo charcoal powder and terylene mixing cospinning form, and fibre structure is loose, and the strength and elongation index of fiber descends than ordinary polyester, so we determine that its dyeing temperature can be lower than ordinary polyester even other terylene, dyeing temperature is 100-115 ℃.
Because cation dyes are positively charged in dye bath, and bamboo charcoal polyester belt negative electrical charge, therefore, cation dyes combine with the anion of bamboo charcoal terylene easily, be adsorbed on fiber surface, be easy to generate the uneven dyeing phenomenon, A Si bends that pH value need be stabilized in 4.5-5.5 when drawing high dyestuff to dye bamboo carbon dacron fiber, because when pH value is 5, can suppress the ionization of anionic group on the fiber, and then the control dyeing rate; When the glauber salt consumption is increased to 2.5g/L when above, help the formation of electronegative fiber surface, the anion that sodium ion slightly occupies fiber dyes seat, and both of these case can reduce dyestuff and just dye rate, improves the level-dyeing property and the stability of dyestuff.
Bamboo carbon dacron fiber is because there is the existence of powdered carbon, its vitrification point is 78～82 ℃, dyestuff need enter the amorphous region of fiber during dyeing, and the microstructure change of amorphous region can reflect by its vitrification point, when amorphous region molecule segment motion fierceness arrives to a certain degree, dye molecule could spread in a large number, so when dyeing temperature is higher than vitrification point, the dyeing rate of dyestuff is accelerated rapidly, because the migration property of dyestuff on fiber can be relatively poor, for the uniformity that guarantees to dye, just to vitrification point the time, stop to heat up at 80 ℃ ± 2 ℃ operation 10-15min, and then reduce heating rate, to improve Color.
Second step, post processing
1, light color (common washing)
Bamboo charcoal modified polyester fibre wool top after the dyeing is placed 2-5% (the heavy percentage of the fabric) liquid of soaping, handle 20-30min for 80-90 ℃.
2, middle dark color (reduction cleaning)
Bamboo carbon dacron fiber wool top after the dyeing is placed the bath of 0.5-2g/L caustic soda (according to shade decision consumption), 0.5-2g/L sodium hydrosulfite (according to shade decision consumption) and 0.5-1g/L non-ionic surface active agent (according to shade decision consumption) composition earlier, handle 20-30min for 70-80 ℃, and then place the glacial acetic acid of 1%-4% (the heavy percentage of fabric) to bathe 40-45 ℃ of processing 10-15min, bath raio: 1: 20-1: 50.
During dyeing, when especially dying dark color, the particle adhesion that some dyestuffs are always arranged is at fiber surface, be not penetrated into fibrous inside, the dye granule of these mechanical bond causes washing fastness, crock fastness, biochemical fastness, drycleaning to descend easily, and the deposition of surface dye is removed in washing that can be common when dying light color; But in dying, when dark, must carry out reduction cleaning when especially dying dark color and handle, to obtain desirable COLOR FASTNESS.
As reductant, caustic soda provides alkali condition with sodium hydrosulfite, and the reduction back takes place dye granule is handled with suspended form by non-ionic surface active agent, through leaving fiber after the flushing; The temperature of reduction cleaning will be lower than the glass transition temperature of bamboo charcoal terylene, ionic compound is impermeable to advance fibrous inside, only reduces the dyestuff of fiber surface, when guaranteeing fastness, do not change the wool top color, so we select the 70-80 ℃ of temperature as reduction cleaning.
