In production, the denim fabric has used following four fiber to the present invention：
(1) cashmere (Cashmere) is a kind of advanced wool textile raw material, have the characteristics that it is light, soft, soft, warm, cashmere it
So it is very precious, it is rare (only account for world animal fiber total output 0.2%) to be not only due to yield, it is often more important that its is excellent
Quality and characteristic, determined the price in transaction with gram, quilt is that the current mankind can it is believed that be " fiber jewel ", " fiber queen "
All textile raw materials utilized are all incomparable, thus are otherwise known as " soft gold ".
(2) Modal fibre (Modal) is a kind of high wet modulus regenerated celulose fibre.With soft, bright and clean, color and luster is gorgeous
It is beautiful, the characteristics such as fabric feeling is smooth, the fabric made with it, a kind of silk face gloss is illustrated, there is pleasant soft touch
Feel and pendency feels and fabulous endurable performance.
(3) cotton fiber (Cotton) is a kind of natural fiber, has soft, ventilative, good hygroscopicity, spy comfortable and easy to wear
Point.
(4) spandex (Spandex) is a kind of elastomer, and scientific name polyurethane fiber, China's Mainland is referred to as " spandex ".Its bullet
Property is excellent, can elongate 6~7 times, but can be promptly restored to original state with the disappearance of tension force, and more resistant to chemical degradation.Ammonia
The resistance to acids and bases of synthetic fibre, sweat proof, dry cleaning resistance, wearability are preferable.
Each process parameter for producing denim fabric to complete cashmere/Modal/cotton/spandex fibre has following spy
Point：
(1) denim fabric made from the production of cashmere/Modal/cotton/spandex fibre it is characterized in that：Fabric with cashmere,
Modal fibre, cotton fiber, spandex fibre blending form, and percentage by weight scope of design shared by its fabric each component is：Goat
Suede 3.0~5.5%, Modal fibre 25~40%, cotton fiber 50~72%, spandex fibre 1.0~2.5%；
(2) cashmere feature：Fineness is thin, and flexibility, warmth retention property are good, and feel cunning is glutinous, and containing grease, electrostatic is big, fluffy, saturation
Power is poor, easily occurs viscous, loose phenomenon in spinning processing on cotton spinning equipment, makes spinning difficult, health is wanted before use, increase can be spun
Property, health preserving adjuvant proportioning is and crude oil 0.1-0.2%, antistatic additive 0.5-1.5%, water 1.5-3% that auxiliary agent is using very few, no
It can improve that fiber electrostatic in spinning process is big, fluffy problem, auxiliary agent is easily caused in spinning process and twined car, networking using excessive
Difficult phenomenon；
(3) two kinds of raw material difference of specific gravity of cashmere and Modal fibre are big, only with mechanical mixture, spin after mixing and easily occur
Incomplete mixing phenomenon, therefore before throwing raw material, first artificial shredding mixes to ensure to mix the cashmere after health with Modal fibre
Uniformly；
(4) due to cashmere the characteristics of, it is easy to lost in spinning process, especially rear the noil and curtain in carding step
Spend middle loss more, to ensure that the cashmere ratio in final products meets the requirements, ingredient proportion is big, and cashmere will by design
The 1.06-1.10 asked, Modal fibre feed intake by the 1.0-1.02 of design requirement, and ingredient proportion is less than normal, may cause finally to produce
Each blended fiber ratio example of product is undesirable, and ingredient proportion is bigger than normal, causes significant loss；
(5) it is difficult to reduce spinning according to cashmere feature, take cashmere coiled in carding procedure with Modal fibre
Into bar, cashmere in cotton cleaning process, is combed more using light quantitative, few beat with Modal fibre, is dropped irregular technological principle, beneficial into
Volume, reduces each portion's Beater Speed to reduce fibre damage, reduces coiled rice weight irregularity.Main technologic parameters：Griping cotton machine hired roughneck
Rib -2~+2mm of distance is stretched out, griping cotton machine is frequently grabbed, grabbed less every time, inspiration raw material is acted on by wind-force, in favor of well mixed；
Griping cotton machine hired roughneck stretches out rib apart from bigger than normal, and crawl raw material block is big, and crawl is irregular；Opener hired roughneck rotating speed 430-470r/min,
Single beater scutcher integrates hired roughneck 850~950r/min of rotating speed, lap roller rotating speed 10-12r/min；
(6) in carding step, licker-in rotating speed is reduced, mitigates the damage to fiber；Doffing speed is reduced in favor of networking, is protected
Card fiber normally shifts, and improves web quality；Reduce cover plate speed, reduce curtain flower, cover plate speed is higher, curtain spend it is more, and
Curtain spends middle cashmere in the majority.Main technologic parameters：Cylinder rotating speed 330-370r/min, licker-in 830~930r/min of rotating speed, road
Husband rotating speed 13-17r/min, cover plate speed 127-162mm/min；
(7) spin afterwards in process, roving twist properly increases, and makes up caused by combing cotton fibre is loose, cashmere is fluffy and lacks
Fall into, roving twist factor 88-98；In spinning process, core siro spinning wheel speed is preferably relatively low, and ingot speed 9000-11000r/min, back zone is led
Stretch multiple grasp less than normal to improve evenness quality, back zone drafting multiple 1.18-1.34, spandex thread and its pre-draft multiple selection with
Fabric elastic recovery is larger preferably, 40D or 70D spandex thread pre-draft multiples 2.75-3.37；
(8) in weaving process, according to denim fabric yarn count made from cashmere/Modal/cotton/spandex fibre production slightly
Slightly, yarn strength and the characteristics of higher ultimate strength, uses 2.7~3.3cn of warp tension in weaving process, and back beam height 90~
110mm, 300~340mm of opening time, it is more plentiful so to knit cowboy's cloth cover of system, close structure, breaks reduced；
(9) in preshrinking process, according to denim fabric blending raw material made from cashmere/Modal/cotton/spandex fibre production
The characteristics of, fabric is before machine is entered through appropriate dewing and heating, 0.4~0.5MPa of blanket cylinder steam pressure.Become fiber
Soft and there is larger plasticity, drying cylinder drying process, to strengthen preshrunk control and raising preshrunk effect.Fabric passes through
During by rubber blanket pre-shrinking, first preliminary drying removes partial moisture, rubber blanket cylinder 0.2~0.3MPa of steam pressure, goes out after machine again through nothing
The felt dryer of tension force is dried and plated, when eliminating compression because shrink it is excessive and caused by wrinkle, preshrinking rate 10~
15%, to obtain plentiful feel and excellent elasticity.
Compared with prior art, the beneficial effects of the invention are as follows：
The present invention is to use several functions using cashmere/Modal/cotton/denim fabric made from spandex fibre production
Fiber carries out rational proportion, employs new technology what is produced, and several fibers are gained the upper hand complementation, and finished product fabric interior quality is high
It is expensive, there is the denim fabric of high added value (dress is warming, environment protection health, comfortable, attractive in appearance, elastic free).The fabric is to human body
Fanout free region, environmentally safe, cloth cover bamboo joint layout is unique, and lines is clear, and gloss is beautiful, comfortable feel is soft, collects four kinds of fibres
The good characteristic of dimension is learnt from other's strong points to offset one's weaknesses in one, has reached and more preferably taken effect.
End part of in August, 2017, the products symbiosis produces 3.6 myriametres, 2,000,000 yuan of income from sales, increases foreign exchange earning 240,000 newly
Dollar, considerable economic benefit and social benefit are brought to enterprise.Product structure is have adjusted to enterprise, lifting product adds
Value, adds profit margin, improves the popularity of enterprise, to promoting this area or even national tencel to be produced in denim
To all good impetus be played by being applied on product.
