Description
Technical field
The invention belongs to textile technology field, more particularly to it is a kind of based on dry spinning technology prepare staple fibre long filament without
The Processes and apparatus of woven fabric.
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-coagulating bath-washing-winding-boundling-
The secondary washing of stretching-curling-cut-out-- wet shredding-drying-shredding-packing.Concrete technology flow process is：1. the preparation of viscose glue：Packet
Include the processes such as dipping, squeezing, crushing, aging, yellow, dissolving, maturation, filtering, deaeration.2. spinning technique：Using wet spinning.
Viscose 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 yellow acid
Ester transformation tissue culture is at cellulose.3. post-processing：Fiber need to be after washing, neutralization, washing, oiling and drying etc. again after forming
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.
In conclusion although dry spinning can prepare staple fibre at present, do not have in actual production and research and development field
Someone expects after obtaining staple fibre long filament with dry spinning technology, carries out the side that lapping prepares staple fibre continuous yarn non-woven fabrics
Method.
