Description

The dyeing and finishing technology of flax and Lyocell fiber mixed fabrics
Technical field
The present invention relates to a dyeing and finishing technology that grows flax with the Lyocell fiber mixed fabrics, belong to textile technology field.
Background technology
Flax and Lyocell fiber belong to cellulose fibre together, the Lyocell fiber is to break into a kind of regenerated celulose fibre that slurry gushes out by certain shape with timber, because of it has ventilative, well-pressed, the easy moisture absorption good wearability such as wet, bacteriostasis antibiosis of loosing, so it is a kind of high-grade textile material, its fabric is high-grade clothing and decorating cloth.But flax fracture rebound degree is little, is about 2%~4%, and elastic stability is poor, skin-friendly is poor, rigidity is strong, and wearability has been subjected to certain restriction.The Lyocell fiber has outside the natural fabric self character, still has good hygroscopicity, comfortableness, glossiness, dyeability and biological degradability, also has and stretches characteristic by force; Aspect weaving, it is fit to various spinning methods; Aspect whole dying, suitable dyestuff is many, the dye-uptake height; Aspect taking, use comfortable moisture absorption, good water-retaining property, wet strong, wet mould height, Heat stability is good, durable in use, can make its good hand feeling by the fibrillation technology.Flax and Lyocell fiber mixed fabrics are the premium properties that utilizes flax and Lyocell fiber, with the advantage of the two kinds of fibers shortcoming of cancelling out each other, make lining after the blending well-pressed ventilative, soft, the clothes superior performance, make that the Application Areas of lining is more wide.But, for a long time, in the dyeing and finishing technology of flax and Lyocell fiber mixed fabrics, exist four big technical barriers restricting applying of sodolin always: the one, in traditional technology, for reaching the bleaching and the purpose of removal of contamination, often use alkali move back+oxygen floats+method that chlorine floats, but too drastic chemical reaction is difficult to guarantee that fiber does not sustain damage, because Lyocell cellulose fibre alkali resistance extreme difference, a large amount of caustic soda can cause fibrolysis.And need a large amount of water to clean to the caustic soda that remains on the fabric in the whole process, and correspondingly produced a large amount of alkaline waste waters, environment is produced influence greatly; The 2nd, because its inherent characteristic of Lyocell cellulose fibre in the dyeing and finishing process, through the friction of equipment, descends fibre cohesion, produce heterodoxy, the surface generates the undercoat plumage.Can pilling effect take place as wool in the wearing process, it is not bright and clean that cloth cover seems, influences apparel appearance.And the tinctorial yield of Lyocell fiber and flax differs greatly, during dyeing the colouring of two kinds of fibers inconsistent, cause the cloth cover uneven color, cloth cover often occurs and grow dim, the color problem such as dark of withering; The 3rd, Lyocell fiber work in-process very easily produces the problem of fibrillation, makes to form long uneven fibril fine hair, and the anti-fluffing and anti-pilling performance is poor, and it is coarse that outward appearance seems; The 4th, the four conventional anti-finishing agents such as the teflon arrangement of gas crust etc., arrangement back lining wiriness, gas permeability is poor, and strength loss is many, and it is restive that look becomes.
Summary of the invention
The object of the present invention is to provide the dyeing and finishing technology of a kind of improved flax and Lyocell fiber mixed fabrics, it not only can keep flax and the original good characteristic of Lyocell fiber mixed fabrics, and strength loss is little, soft, the lovely luster is beautiful, and every chemical index all meets the Oeko-Tex100 requirement.
Its technical scheme is: a dyeing and finishing technology that grows flax with the Lyocell fiber mixed fabrics, comprise singe, destarch kiering, oxygen are floated, tentering goes wrinkle, dyeing and four anti-finishing technique steps, it is characterized in that:
1) after the singeing step, before the destarch boiling step, adopts biological enzyme formulation to carry out cold dome and dispose;
2) adopt low alkaline scouring, hydrogen peroxide bleaching one-step method;
3) before dyeing, adopt polybasic carboxylic acid class crosslinking agent EH that the Lyocell fiber is prevented the fibrillation processing;
4) after dyeing, adopt cellulase to carry out the flexibility arrangement:
5) adopt nanometer finishing agent to carry out four anti-arrangements.
Its technique effect is:
1, adopt biological enzyme formulation to carry out cold dome and handle, the pectin in the flax fibre is effectively decomposed, wax and some natural impurity become and have removed easily, use low alkali treatment for following process and have created condition.Simultaneously, because biology enzyme damages brute force hardly, low alkali is also less to the damage of fiber, has reached the purpose that guarantees that promptly the semi-products quality requirement does not make fiber strength descend again, for following process lays the foundation.In addition, adopting biological enzyme formulation to carry out cold dome handles, also greatly reduce the consumption of following process alkali treatment, reduced the damage of caustic soda to the brute force of linen fibre and Lyocell fiber, kept the original natural style of fiber, and reach the consumption that reduces chemical agent, reduced blowdown, reduced energy consumption.

The dyeing and finishing technology of flax of the present invention and Lyocell fiber mixed fabrics, not only kept the original good characteristic of flax lining, and four anti-performance good, strength loss is little, dyefastness is high, has airing function, technology is reasonable, according to detection, every chemical index of product all meets the Oeko-Tex100 requirement; And advantages such as that this technology has is easy and simple to handle, easy control of process conditions.
The specific embodiment
One, kind: 63 inches of 11*11/48*42 grey cloth fabric widths
Two, dyeing and finishing technology:
1, singe:
Because the linen fibre rigidity is strong, surface hairiness is more, and bright and clean for making fabric face, color and luster is even during dyeing, singes to seem particularly important.Simultaneously, take into account the characteristic of regeneration Lyocell fiber, do not damaging under the two powerful situation, adopt gas singeing machine to carry out high speed and singe.Gas singeing machine should dispose two burners that spray, and the burner flame temperature is 1200~1300 ℃, under the quick condition of high temperature, can guarantee both burning-off fine hair, does not damage fiber again, singes that it is three positive three anti-to adopt, the speed of a motor vehicle be 80-85 rice/minute.
Be the raising quality of singing, before entering burner, adopts in fabric the steam dewing, plate through the oven dry of 12 drying cylinders afterwards, the moisture content of so both rationally having controlled fabric has solved the uneven singeing problem that folding line (wrinkle) problem because of grey cloth causes again below 5%.Strengthen bristle again, the bristle roller adopts rigidity bristle roller, and the feather that makes lodging is erecting of brush as far as possible, through three positive three anti-singing, can improve the quality of singing greatly then.
2, the biology enzyme cold dome is disposed
The biological enzyme formulation that adopts Denmark Novozymes Company to produce.This biological enzyme formulation is a kind of plurality of enzymes compound system based on alkaline pectin acid cleavage enzyme, optionally decompose pectic substance in the flax fibre by pectase, the decomposition of pectic substance helps the removal of wax and other impurity, keeps fiber strength to greatest extent, and is soft.Use the cold rolling heap machine of printing and dyeing, in every liter working solution, add 5-10 gram SKD enzyme, add 5 gram nonionic penetrant JFC simultaneously, regulate pH value with soda ash and make it reach 7-8,, during by padding machine the liquid carrying rate on the grey cloth is adjusted to 110-130% to be steam heated to the 50-60 degree, through clot grey cloth is broken into the web-like coiled hair, be placed on the indoor of environment temperature 25 degree, keep rotating 20 hours, so that enzyme fully acts on grey cloth.
3, low alkaline scouring, hydrogen peroxide bleaching:
Because the biology enzyme cold dome is disposed, pectin in the flax fibre is effectively decomposed, wax and some natural impurity become and have removed easily, greatly reduce the consumption of following process alkali treatment, reduced the damage of caustic soda to the brute force of linen fibre and regeneration Lyocell fiber, keep the original natural style of fiber, and reached the consumption that reduces chemical agent, reduced blowdown.Use is moved back and is boiled rinsing combination machine; the grey cloth of banking up 20 hours with enzyme is handled; with the running water is in the base fluid destarch working solution; add 8-10 gram caustic soda at every liter water; add digesting agent ZT-9036 gram and sodium sulfite 5 grams simultaneously; spend with Steam Heating to 80; be heated to 100 degree decatizes 50 minutes with the decatize case in the desizing machine; the slurry of washing to remove on the fabric by the hot water of 90 degree reaches the destarch purpose again; cloth after the destarch is bleached processing; handle with moving back the oxygen bleaching machine that boils in the rinsing combination machine; with the running water is in the base fluid bleaching working solution; add 6-7 gram hydrogen peroxide at every liter water; add ZT-604 protective agent 10 gram and digesting agent ZT-9035 gram simultaneously, use decatize case in oxygen bleaching machine decatize 40 minutes under the conditions of 100 degree, wash by the hot water of 90 degree again; remove impurity on the fabric with this, improve whiteness and reach the bleaching purpose.
4, tentering goes wrinkle
In order to overcome the generation of wrinkle bar, in process of production, except carrying out equipment cleaning work, some equipment to pre-treatment have carried out relevant debugging and transformation, for example: float bonus point roll dies and roller in the washing trough of operation hot water boiling, advance cloth and adopt centralising device, overcome the into skew problem of cloth well, overcome the generation of wrinkle bar to a great extent, but in actual production, cloth cover or out-of-flatness still have certain influence to the follow-up processing of dying, print, Given this we adopt and carry out squezzing at stenter, have solved the smooth problem of cloth cover.In addition, consider in pre-treatment processing that mostly fabric is that the internal stress between the fiber also is not eliminated well through compact form processing, process squezzing is tentering again, has also solved this problem, has reached the effect of getting twice the result with half the effort.
5, anti-fibrillation is handled:
Fibrillation is one of characteristic of common regeneration Lyocell fiber easily, and fibrillation is meant that fiber surface divides tiny microfiber (diameter 1-4um).Regeneration Lyocell fiber easy fibrillation under moisture conditions influences the coloration of textile materials outward appearance.So needing to prevent fibrillation before dyeing handles, adopt polybasic carboxylic acid class crosslinking agent EH that regeneration Lyocell fiber is handled, make regeneration Lyocell fiber obtain good antigen fibrillation performance. take all factors into consideration the antigen fibrillation performance of regeneration Lyocell fiber and the damage of fibre machinery performance, we adopt contactless drying plant, the consumption of polybasic carboxylic acid class crosslinking agent EH: with the running water is base fluid, adds 10 gram polybasic carboxylic acid class crosslinking agent EHs in every liter water.
6, dyeing:
Dyeing notes controlling well coloured light, notes the problem of the uniform coloring of cloth cover, comes selective staining technology according to color, generally adopts the dyeing of REACTIVE DYES or reducing dye, and we select the dyestuff of HUNTSMAN for use.
7, the flexible arrangement of cellulase:
Because the characteristic of the inherent characteristic of linen fibre and four anti-arrangements can produce bigger influence to the feel of lining.Flax feel is relatively poor and four anti-arrangements influence feel, owing to will reach decontaminable effect, can not use softener again, therefore must use other method, early stage pliability is significantly promoted, and offsets the influences of four anti-arrangements.Through test repeatedly, adopt the biological environmental production technology of cellulase to reach this purpose.With water is in the working solution of base fluid, adds 10 gram cellulase 7000L in every liter water, regulates pH value 5-6 with glacial acetic acid, handles 10 roads with Steam Heating to 50 degree in dye jigger, cleans 1 with clear water at last and says the cylinder oven dry.
8, four anti-finishing techniques:
Adopt nanometer finishing agent to carry out four anti-arrangements.Amido silicon oil NSW, waterproofing agent NT-X604A, oil-proofing agent NT-X604B, anti-fouling agent NT-X603D, resin NT-X603E and composite catalyst NKS that nanometer finishing agent is produced by U.S. NANO-TEX company, nano assistant all is manufactured goods, in every liter water, add amido silicon oil NSW 2 grams, waterproofing agent NT-X604A 40 grams, oil-proofing agent NT-X604B 40 grams, anti-fouling agent NT-X603D 15 grams, resin NT-X603E 15 grams, composite catalyst NKS 10 grams; Prepare and use the glacial acetic acid carwash, pad fabric with the four anti-liquid that prepare, to the 120-130 degree, drying cylinder was dried 90 seconds with Steam Heating.
Annotate: the cleaning requirement to equipment before carrying out four anti-arrangements is very high, and clean with acidic aqueous solution after all will cleaning with the washing agent of environmental protection in the place of processes that cloth moves such as the deflector roll on the equipment, roll, drying cylinder again, guarantees four anti-effects of putting in order.
It is shrinkproof to carry out tentering after the four anti-arrangements.
