Placement core filaments are pulled on, conveying roller operating drives core filaments unwrapping wire, and core filaments pass through coating machine spindle to make under certain draw ratio
Linear motion since coating machine spindle is sequentially connected with transmission mechanism and drives high-speed motion by transmission mechanism at this time, makes aluminum pipe
On outsourcing silk at the uniform velocity unwound with certain steering, uniformly by the core filaments to move along a straight line cladding get up to form cladding
Yarn batches sieve take-up by by being located above covering machine, in yarn winding to paper tube, will complete entire cladding process；Wherein
Cladding process is twists with the fingers 500 TPM -600TPM, outer sth. made by twisting 400 TPM -5000TPM, drawing-off 110%-300%, because of core filaments kind in double-contracting
Class, specification are different and adjust, and coating machine spindle rotating speed is 7000 m/min-10000 m/min.
The preparation method of the novel imitation leather elastic fabric wrap yarn of production of the present invention, further preferred technical side
Case is：The thickness of the outsourcing silk is 70D-500D, and core filaments are common coloured spandex, thickness 20D-100D.
The preparation method of the novel imitation leather elastic fabric wrap yarn of production of the present invention, further preferred technical side
Case is：Step（4）The draw ratio of middle core filaments, core filaments are spandex, and draw ratio is 2.5-3.0 times, and core filaments is polyamide fibres or wash
Synthetic fibre, draw ratio are 1.1-1.2 times.
The application of the wrap yarn of production novel imitation leather elastic fabric of the present invention according to prepared by any of the above-described, feature
It is：Above-mentioned wrap yarn is scalded surely by being knitted to form fabric, fabric by scalding machine surely, and surface layer low melting point spandex melts bonding,
The film layer of leather effect is formed in textile surface.
The present invention, as outsourcing wire material, is coated on the elasticity or non-such as polyamide fibre, terylene, spandex using low melting point spandex material
Wrap yarn is spun into outside elastic material long filament.And it is made into this wrap yarn by machines such as weft machine, tricot machine, looms
Fabric, then the fabric being made into is scalded surely by scalding machine surely, surface layer low melting point spandex melts bonding, forms pole like leather surface
The garment material of effect and feel；Not only the very high manufacture of efficiency is at low cost, but also environmental protection, unlike being generated using fabric coating technology
Waste water and gas etc..In addition the outsourcing wire material used is fibers material, therefore stability is very high for spandex, and it is old will not to generate leather
Change, chap, the problems such as decoloration, while acid and alkali-resistance, water-fast, insect prevention is mothproof etc..There are no use low melting point spandex in the prior art
It coats other materials and this fabric of wrap yarn making is made, in addition because of the characteristic of low melting point spandex, there is certain gluing to stick
Property, therefore process very inconvenient.
Compared with prior art, the present invention uses low melting point spandex as outsourcing silk first, first will be low in preparation process
Fusing point spandex carries out rewinding procedure processing, as the preparatory process before winder, can improve moving back for outsourcing silk low melting point spandex
It around performance, is used convenient for next procedure, therefore production is made to realize continuity, improve production efficiency, while make this low melting point
Wrap yarn of the spandex as outsourcing silk because of the characteristic of low melting point spandex, is heat-treated it on rear road finished product, so as to make
Spandex deforms upon, and forms the film layer of leather effect in textile surface, can be used for imitation leather elastic fabric.
Specific embodiment
The specific technical solution of the present invention described further below, in order to which those skilled in the art is further understood that
The present invention, without forming the limitation to its right.
The present invention is a kind of preparation method for producing novel imitation leather elastic fabric wrap yarn, and its step are as follows：

Color spandex is connected with as core filaments；
（2）Outsourcing silk is subjected to rewinding procedure processing, improves the backing-off performance of low melting point spandex outsourcing silk；Rewinding procedure processing step
It is rapid as follows：Using rewinder, low melting point spandex outsourcing silk is allowed to pass sequentially through tensioner（Tensioner at this time does not have adjusting
The function of power, but play the role of fixed outsourcing silk）, fracture of wire inductor, the bar of falling yarn, with molding curved frame pull forming it is convex
Low melting point spandex is perfectly wound on tube by plate, in favor of winding procedure use, while the speed of rewinding for 300m/
Min stretches 125% technological parameter, so as to which low melting point spandex be enable smoothly to unwind.
（3）Rewinding procedure treated outsourcing silk is subjected to winding procedure processing, it is made to be wrapped on aluminum pipe；Winding procedure
Step is as follows：On the board putting things that rewinding procedure treated low melting point spandex outsourcing silk is placed to bobbin-winding machine, outside low melting point spandex
Packet silk passes sequentially through conducting wire pole, and tensioner, filar guide, is twined onto aluminum pipe tension link, and aluminum pipe is placed on spindle, after booting, in ingot
Aluminum pipe rotates under the drive of son, low melting point spandex outsourcing silk is made uniformly to be wound on aluminum pipe as required, wherein the speed of bobbin-winding machine
It spends for 400 m/min, on-line tension 6g.
（4）Aluminum pipe after winder is placed on coating machine spindle, core filaments pass through coating machine spindle under 2.5 times of draw ratios
For linear motion, coating machine spindle drives aluminum pipe high speed rotation, and outsourcing silk is at the uniform velocity unwound with certain steering, uniformly will just
In the core filaments cladding to move along a straight line, wrap yarn is formed；Specific steps：Using covering machine, by the low melting point spandex of the good cylinder of network
Outsourcing silk is placed on the coating machine spindle for the covering machine that aluminum pipe can be driven to rotate, and coating machine spindle is sequentially connected with transmission mechanism
And it is driven and moved by transmission mechanism；Spandex core filaments are placed on conveying roller below covering machine, conveying roller operating drives ammonia
Synthetic fibre core filaments unwrapping wire, spandex core filaments pass through coating machine spindle for linear motion under 1.1 times of draw ratio, due to coating machine at this time
Spindle is sequentially connected with transmission mechanism and drives high-speed motion by transmission mechanism, makes the low melting point spandex outsourcing silk on aluminum pipe with one
Fixed steering is at the uniform velocity unwound, and uniformly the core filaments to move along a straight line cladding gets up to form wrap yarn, by by being located at
Sieve take-up is batched above covering machine, entire cladding process in yarn winding to paper tube, will be completed；Wherein cladding process is double-contracting
Interior sth. made by twisting 570TPM, outer sth. made by twisting 460TPM, drawing-off 250%, coating machine spindle rotating speed are 10000 m/min.
（5）Wrap yarn is handled by rewinding procedure up to product, and wherein rewinding speed is 500 m/min, and on-line tension is
6g。
