Description
Technical field
The invention belongs to technical field, more particularly to one kind preparing viscose fiber filament non-woven fabrics based on wet spinning technology
Processes and apparatus.
Background technology
Non-woven fabrics (English name：Non Woven Fabric or Nonwoven cloth) it is also known as nonwoven fabric, it is a kind of non-
Woven cloths are to be made of fiber orient or random, are environment-friendly materials of new generation, have it is moisture-proof, ventilative, flexible, light,
Not combustion-supporting, easy the features such as decomposing, is nontoxic nonirritant, rich in color, cheap, recyclable.Such as mostly use poly- third
Alkene (pp materials) pellet is raw material, batches continuous one-step through high-temperature fusion, spinneret, lapping, hot pressing and produces.Because having cloth
Appearance and certain performances and be called cloth.Because it is a kind of need not spin cotton and weave cloth and the fabric formed, only will weaving
Staple fiber or long filament are oriented or random alignment, forms fibre net structure, is then added using the methods of mechanical, hot sticky or chemical
Admittedly forming.New type of fibrous product with a soft, breathable and planar structure, advantage are not generate Soft flocks, tough, durable, silk
As soft and reinforcing material one kind, and the feeling of also cotton is compared with cotton goods, and the sack of non-woven fabrics is easy into
Shape, and low cost.Bonded fabric product is rich in color, bright-coloured bright and beautiful, Eco-Fashion, widely used, beautiful and generous, pattern and
Style is all various, and light, environmentally friendly, recyclable, by the internationally recognized environment-friendly products for ecology of preserving our planet.Suitable for agriculture
With film, shoemaking, process hides, mattress, child-mother-covering, decoration, chemical industry, printing, automobile, building materials, the industries such as furniture and dress lining cloth,
The gift of health care disposable surgical clothing, mask, cap, sheet, the disposable tablecloth in hotel, beauty, Saunas or even current fashion
Bag, fine work bag, shopping bag, advertising bag etc..Environment-friendly products, it is widely used, it is economical and practical.According to different application field, it can have
Have：Light, soft, water repellent, ventilative, nontoxic, nonirritant, antibacterial, anti-chemical agent, antibiotic property.Prepare non-woven fabrics master at present
If directly utilizing high polymer (spinning) slice, staple fiber or long filament that fiber by air-flow or mechanical networking, is then passed through water
Thorn, needle thorn or hot rolling are reinforced, and the non-woven cloth finally formed by final finishing, that is, fiber are laggard through dry spinning
Prepared by row, staple card networking may be used, or use fiber filament spunbond networking, and production technology includes mainly spunbond
Method, meltblown, Hot rolling, spun lacing method, needle point method.Because it is a kind of need not spin cotton and weave cloth and the fabric formed, only will
Textile staple or long filament are oriented or random alignment, forms fibre net structure, then uses the side such as mechanical, hot sticky or chemical
Method is reinforced.Non-woven cloth breaches traditional weaving principle, and it is short with technological process, throughput rate is fast, yield is high, at
The features such as this is low, purposes is wide, raw material sources are more.
Continuous yarn non-woven fabrics are to prepare continuous yarn non-woven fabrics using spun-bond process in field of textiles and actual production, are to polymerize
Object has been extruded, has been stretched after forming continuous filament yarn, and long filament is laid with networking, and fibre web is viscous using itself bonding, heat bonding, chemistry
Conjunction or mechanical consolidation method, make fibre web become non-woven fabrics.Continuous filament yarn prepares non-woven fabrics：Using spun-bond process；Staple fiber prepares nothing
Woven fabric：Mixing, shredding are reinforced after combing networking using needle thorn, spun lacing or thermal bonding.Continuous yarn non-woven fabrics and staple fiber nonwoven fabric
It compares, can so that non-woven fabrics is more thin, intensity is more preferable, but prepares continuous yarn non-woven fabrics at present and mostly use spun-bond process, fine
Dimension can only also use the hot melts synthetic fibers such as terylene, polypropylene fibre, polyamide fibre and spandex, can not use the regenerated fiber system of superior performance
It is standby, although and synthetic fibers intensity is good, flexibility, water imbibition and comfort are poor, this application in continuous yarn non-woven fabrics
Field is obviously restricted.Currently, the main technological steps of wet spinning are：Spinning solution-solidification-washing-winding-boundling-drawing
It stretches-curling-and cuts off-secondary washing-wet shredding-drying-shredding-packing.Concrete technology flow process is：1. the preparation of viscose glue：Including
The processes such as dipping, squeezing, crushing, aging, yellow, dissolving, maturation, filtering, deaeration.2. spinning technique：Using wet spinning.It is viscous
Glue forms thread by spinneret orifice and enters the coagulating bath containing acid, and alkali is neutralized in viscose glue, and thread is frozen into strand, cellulose xanthate
Transformation tissue culture is at cellulose.3. post-processing：Fiber need to be after washing, neutralization, washing, oiling and drying etc. again after forming
Reason processing.Wet spinning not only needs the stoste that type is various, bulky to prepare and prepares equipment before spinning, but also to have solidification
Bath, cycle and reclaimer, technological process is complicated, factory building and equipment investment are expensive, spinning speed is low, therefore cost
It is higher.Staple fiber can be made in this method, and fiber filament can also be made, and traditional application is staple fiber directly by fine with other
Tie up it is blended, after combing networking carry out non-woven fabrics production, fiber filament be directly sent to after packing the enterprising hand-manipulating of needle of loom knit or
It is woven.It follows that obtain continuous yarn non-woven fabrics, can only be obtained through spunbond networking post-reinforcing using dry spinning, because of fiber
Long filament is after wet spinning if cut into staple fiber again combs networking production non-woven fabrics with other fibers, due to wet spinning sheet
Body complex process, cost are higher, and the production cost of non-woven fabrics will be greatly increased by doing so, and increase the complexity of technique.At present
Anyone is had no in field of textiles to expect with wet spinning technology during preparing viscose fiber filament, utilizes spun lacing
Step is cleaned, saves the more of winding, boundling, stretching, curling, cut-out, secondary washing, wet shredding, drying, shredding and packing
A processing step carries out lapping and reinforces the technique for directly producing non-woven fabrics,
103320968 A of CN disclose a kind of manufacturing method of continuous yarn non-woven fabrics, which is walked using following technique
Suddenly：Filament fiber is unwound first with creel；Filament fiber includes polyphenylene sulfide fibre, aramid fiber, polytetrafluoroethylene (PTFE)
Fiber, viscose rayon, polyimide fiber or polyacrylonitrile fibre and carbon fiber, glass fibre or basalt fibre, and it is long
Silk fiber is non-twist continuous filament yarn, and fineness is 1 μm -200 μm；Ultrasonic washing filament fiber is used again；Thereafter single fiber is utilized
Drying unit dries filament fiber；Then filament fiber tubular drafting device drawing-off is sent by speed governing roller and tensioner to carry
Speed, then by the evenly dispersed filament fiber of pendulum wire device, and putting into filament web at lace curtaining upper berth；Finally by needle thorn, water
Continuous yarn non-woven fabrics are made in filament web by thorn or the method for processing nonwoven fabrics of hot rolling.
104480642 A of CN disclose a kind of preparation process of non-woven fabrics, including：It is sent into after PP feed stock chips are dried
Screw extruder evenly distributes from spinneret orifice again through die head after melt extruded, filtering, metering and sprays to form as-spun fibre；Just
Raw fiber is uniformly laid on lapper lapping curtain, the filament web of formation after air-flow cools down drawing-off by diffusor duct, is passed through
Hot rolling, winding become non-woven fabrics after cutting.
CN103352318A discloses the production technology that a kind of pearl fiber combines spunlace non-woven cloth with viscose rayon, uses
Pearl fiber and viscose rayon are raw material, and sequentially enter shredding process, carding step, lapping process, drafting process, spun lacing work
Sequence, baking operation, on-line checking process, coiling process, cutting process；Wherein, in shredding process, pearl fiber and viscose rayon
Shredding is carried out respectively, feeds corresponding carding machine hopper；In carding step, viscose rayon is combed to obtain using carding machine one
Viscose web, using high speed, carding machine two is combed to obtain pearl fiber net pearl fiber in a jumble；In lapping process, viscose glue
Web uses cross lapping, and pearl fiber net is using straight paving.
Although the technique that 103320968 A patents of above-mentioned CN prepare non-woven fabrics using long filament breaches the short fibre of tradition utilization
Dimension combs pattern prepared by networking preparation or fiber filament spunbond networking heat bonding, but through the finally obtained fiber of wet spinning
Its production technology of long filament itself is more complex, and fiber filament is not knitted and does non-woven fabrics, increases the production cost of non-woven fabrics, this
The policy of China's energy-saving and emission-reduction and the strategy of sustainable development is not met, 104480642 A patents of CN are then that traditional spun-bond process is long
Silk non-woven fabrics preparation process, representative of the CN103352318A patents as traditional blended weave, belongs to dry method lapping, is not to adopt
With the direct lapping of the direct wet spinning of viscose fiber filament, it is unable to reach thin, the saturating effect of viscose fiber filament non-woven fabrics.
Viscose rayon because its soft texture, pendency degree is good, dyeability is good, bright in luster, good hygroscopicity, uncomplicated laundering it is excellent
Point, and spinnability is excellent, Chang Yumian, hair or various synthetic fibers are blended, interweave, are used for all kinds of clothes and decorative textile product.
Due to the wide application field of current non-woven fabrics, viscose rayon non-woven fabrics be more and more applied to mattress, decoration, chemical industry,
Printing, automobile, building materials, the industries such as furniture and dress lining cloth, facial mask, health care disposable surgical clothing, mask, sheet, hotel
The disposable tablecloth, or even the gift bag of fashion now, fine work bag, shopping bag, advertising bag etc..Viscose rayon non-woven fabrics passes at present
System production method is added using a variety of staple card networkings including viscose rayon as disclosed in CN103352318A
Gu directly using viscose fiber filament lapping reinforcing, the nothing that staple card networking produces as disclosed in 103320968 A of CN
Woven fabric is thicker, and performance is poor, and application field is relatively narrow, and due to being mixed with other fibers, the performance of viscose rayon can not obtain
To effective method for embodying, and using viscose fiber filament lapping, cost is too high, is not suitable for promoting and applying.China's viscose glue is fine
It is big to tie up demand, but due to inevitably generating the pernicious gases such as CS2, H2S in preparation process, pole is injured to health
Greatly, therefore low cost and high performance viscose rayon non-woven fabrics how is prepared as field of textiles technical staff difficulty urgently to be resolved hurrily
