Description
The present invention relates to a kind of preparation technology of cotton knitwear, belong to textile technology field.
In recent years, the performance of cotton products is familiar with by people, still, the low in glossiness of cotton products, flexibility is poor, and feel is bad, and the big grade of washing shrinkage has limited its development, and this just need adjust, improve performance, to satisfy various requirement.At present, yarn mercerising, yarn singeing, grey cloth mercerising, grey cloth are singed as the existing report of single technical matters, but only limit to research, test, single process operation stage, far can not adapt to large-scale production, especially fairly large production.
The object of the present invention is to provide the two preparation technologies that singe of mariages light of cotton knitwear a kind of maturation, that can adapt to large-scale production.
Purpose of the present invention can be realized by following scheme:
The two preparation technologies that singe of the mariages light of described cotton knitwear, comprise mercerising, the operation of singing, it is characterized in that its concrete processing step is followed successively by: yarn singeing, yarn mercerising, yarn dyeing, braiding, grey cloth are singed, grey cloth softness, grey cloth mercerising, typing, at last cotton knitwear.
The translational speed of yarn is 650～850m/min during yarn singeing, and optimum value is 800m/min, and the tension force of yarn is 1.5～2Kg/cm
2Yarn passes through burned flame fast, removes the filoplume of yam surface, reaches the effect of yarn any surface finish, and its cleanliness factor can reach more than 80%.
The yarn mercerising mainly is the glossiness that increases yarn, improves affinity and the intensity of yarn to dyestuff.Behind the yarn mercerising, its internal junction crystalline region changes, and crystal region reduces to 68～70% by original 82～87%, because the increase of noncrystalline domain, fiber is accelerated dye absorption rate, and dye-uptake improves.Mercerization adopts the method for handling with alkali lye.The technological parameter of yarn mercerising is controlled to be: alkali (NaOH) liquid concentration is that 27～30 ° of Be tension force are that 20～25 ℃ of mercerising times are 120～140s for the power temperature than raw yarn long 2%.
During yarn dyeing, selected suitable dyestuff and auxiliary agent, and adjusted technology, be specially: heating rate is 0.5-1 ℃/min; Reinforced branch adds for three times; Alkali number with hot water injection's yarns of 70～80 ℃; Used dyestuff is the KN type dye; With leveling agent o is retarding agents; Dyeing temperature is 90 ℃, and color fixing temperature is 80 ℃.
The translational speed of grey cloth was 60～70m/min when grey cloth was singed, and the tension force of grey cloth is 1.5～2Kg/cm
2This is to singe for the second time, and purpose is the filoplume that is created in blank cloth surface in the burning-off knitting process.
The grey cloth mercerising is in order further to improve the glossiness of grey cloth, the stability of controlling dimension, improve the cloth cover feel, make fabric face Paint Gloss, prevent the edge-rolling of single face fabric, the technological parameter of operation is that alkali (NaOH) liquid concentration is that 260～280g/l mercerising tension force is that 25～30Kg mercerising temperature is to be that 5～6min mercerising speed is 15～17m/min 20～25 ℃ of mercerising times.
In order to strengthen mercerization effect, accelerate mercerising speed, need to add mercerizing assistant in the alkali lye, we choose Tianjin and reach the mercerizing assistant FM-3A that an outstanding company produces from no phenol mercerizing assistant alkyl sulfide sodium commonly used, hydrocarbyl sulfonic sodium, pure ether compound, alkamine compound, organic acid compound, organic amidated compound, phosphate compounds.
After mercerising was handled, the acetum lixiviating of the alkali lye on yarn and/or the grey cloth finally reached pH value and is 6～7 more suitable.
For stability and the pleasant softness that further improves grey cloth, grey cloth also will be handled through soft and typing, and grey cloth is soft with 910
#Softener, bath raio are 1: 8, and treatment temperature is 100 ℃.
The typing of grey cloth is treated to:
Stentering forming: tentering 175cm
Cloth speed 15m/min
Temperature 130
Grey cloth preshrunk 10m/min abb finishing automatically is adjusted
In the present invention, singe, the mechanism of mercerising is as follows:
Singe:
Staple fibre has a large amount of gloss filoplumes on yarn in spinning process, directly influence the gloss of yarn, and the grease on the yarn, wax ester have a strong impact on the dyeing of yarn.The processing of singing of yarn, grey cloth has strengthened glossiness, has improved last chromatic effect.
Mercerising:
Mercerising is can improve fabric sheen from changing the manufacturing procedure of knitted fabric characteristic in essence one, improves the anti-intensity that rises, and strengthens dyeing uniformity and tinctorial yield, improves elasticity, guarantees size stability, can make the final washing shrinkage of knitted fabric reach 2～3%.
Mercerising is analyzed from following several respects the effect of fiber:
In order to understand this problem, we begin from swelling and backtwisting earlier, when cotton fiber is handled with concentrated alkali solution, the cotton fiber cross section that original not specification is similar to the broad bean shape becomes more and more round, and the cell disappearance, the variation of length and width can take place in cotton fiber simultaneously, is exactly swelling.Under swelling action, what fabric became is more abundant tight.And, in high concentration alkali solution, handle cellulose fibre, can cause the contraction of the wide and length of cellulose, amount of contraction is inversely proportional to the power that applies, this contraction is corresponding with the increase of cellulosic material volume, be swelling cause a kind of, swelling also can cause the variation of fiber cross section, when processing is to increase under the tension force to carry out, then fiber become round.Meanwhile, it is more glossy that fiber surface becomes, and by swelling, the distortion of fiber disappears, and this is that the result causes the backtwisting of fiber, the glossiness of fortifying fibre because the outer fibril layer of fiber more dwindles than internal layer.
Mercerising is processed the influence to cellulose fibre character:
(1) to the influence of gloss
The gloss of cellulosic material (yarn and fabric) is decided with the characteristic of fiber and yarn, the characteristic of fiber comprise cross section shapes and all once, spirality, surface roughness and transparency etc., the characteristic of yarn comprises the twist, compound with regular structure degree and fineness etc., mercerising is handled the gloss that causes cotton fiber to be increased, the characteristic of fabric and surface obtain changing, change more orienting reflex into by the diffuse reflection to light before the mercerising, increased catoptrical intensity, thereby made fabric demonstrate soyeux gloss.
(2) influence to dyeing
Mercerization causes fiber crystal region volume to reduce, degree of crystallinity about 70% before by mercerising reduces to 50～60%, the crystal region area increases, this processing, change the quality of fiber, particularly changed their accessibilities in aqueous medium, so the mercerising fiber has had bigger wettability power, the chemical reagent aqueous solution there is bigger reagency, higher accessibility is arranged with dye molecule.Mercerization has increased the absorption (dyestuff dye-uptake) and the dyeing rate of dyestuff, and has increased the vision tinctorial yield.
(3) mercerising is to the influence of brute force
Because the effect of concentrated base makes the fiber swelling, big intermolecular force is destroyed, hydrogen bond rupture, under straight laterally forceful action, the macromolecular arrangement trend of fiber is neat, the degree of orientation is improved, eliminated the uneven distortion of fiber surface, reduced weak link, the big molecule of some bendings is originally unfolded to be stretched, molecules align is neat, and is stressed even, via the fiber of expanded rearrangement, be close to mutually, embrace and power improves, eliminate or reduced the factor that fiber ruptures because of molecule slippage greatly, so its brute force increases.
(4) mercerising is to the influence of dimensional stability for fabric and washing shrinkage
In the mercerising process, owing to the swelling of cotton fiber in concentrated caustic solution broken and weakened active force between original fiber macromolecular chain, alleviate the internal stress that stores in the fiber by the fracture hydrogen bond, reset by stretching then, big molecular link is set up new molecular link on new position, fiber molecule tend to arrange and intermolecular active force than original swelling before molecular force big.Applying lixiviating under the brute force at last, a large amount of new hydrogen bonds have been formed between the fiber of orientations, like this, fiber is more natural, and new stable state is fixed, and at this moment fiber is in lower energy state, reach dimensionally stable, the also corresponding decline of washing shrinkage, mercerization simultaneously also makes COTTON FABRIC wrinkle resilience obtain moderate improvement, thereby has partly prevented because the tensile strength that the flatiron arrangement causes reduces.
Step of preparation process of the present invention is reasonable, and parameter stability can adapt to large-scale production.By the cotton knitwear of the present invention preparation, its performance has obtained improving greatly, is mainly reflected in glossiness, soft, aspect such as washing shrinkage is little.The key technical indexes is as follows after testing:
It is blunt to 3.2% vertical 2.7% to shrink
Barium value 165
Glossiness 80
