Textilene is the extraordinary textile of no shuttle machine production, using the complex yarn of special packet complex structure, i.e. PVC/PET skin
Core pattern yarn.Core uses high-strength polyester industrial long filament, and cortex is ageing-resistant, polyvinyl chloride (PVC) material of ultra-violet radiation resisting
Material.Polyester filament is extended cladding, and Jing Laguang is cooled into smooth surface, Water-proof and oil-proof, nontoxic, cooling feeling recombination line.Warp thread
Beam of a loom is made by warping machine, directly weaving networking, then final products are organized into, such as beach chair, window blind, gardening, building
And protective fence, decoration, table mat, plate mat, coaster, tablecloth, carpet, tarpaulin of agricultural etc..Terylene has good resistance to
Hot, creep resistance, fatigue durability, rub resistance and abrasiveness, electrical insulating property and chemical resistance, but the brittleness of terylene compared with
Greatly, cause to apply and be restricted.
The structure of common PVC/PET core-skin type yarn is one layer of PVC material of polyester multifilament external sheath, the disadvantage is that should
Covering thread section seems rougher since polyester multifilament part is prominent, unsightly, and since polyester multifilament is relatively soft, product
It is not well-pressed.Its solution is found as covering thread through relevant test using PVC cladding polyester monofilament, and PVC coats terylene
The fibre section of monofilament is smooth, so that manufactured textile is beautiful.But there are problems that one is difficult to overcome because of terylene list
The surface of silk is more smooth, and roughness is inadequate, and bond stress is inadequate, preferable cladding is unable to reach, to affect product quality.
Polystyrene-Polyethylene-polybutene-polystyrene (SEBS) is a kind of multiduty novel thermoplastic elastomer,
It is thermoplastic block copolymers SBS molecule unsaturated double-bond by new modified elastomer prepared by selection plus hydrogen.With excellent
Different resistance to ozone, UV resistant, corrosion resistance, wearability, flexibility and electric insulating quality, and can reuse, mechanical property
Can also preferably, it has been more than vulcanized rubber that elongation at break, which is 0~150%,.How to make full use of the good characteristic of SEBS resin with
The low cost and high performance feature of polyester fiber prepares complex yarn, expands its application field, will hold out broad prospects.

Select HT type polyester filament.
It is further preferred that the number of impregnation is no less than 2 times in step 1.
It further include as a preferred technical solution, pigment in the PVC plastic masterbatch, it, can by adding different pigment
To obtain different colors, the pigment mainly common Masterbatch of plastics in the prior art.
It is further preferred that in the PVC plastic masterbatch, also containing the EVA for accounting for PVC plastic masterbatch quality 5%-10%.
Inventor is found surprisingly that, a small amount of EVA is added, and can be very good the elasticity and pliability that promote PVC coating modification dacron thread.
In step 3, temperature of plate is 150-170 DEG C, and extruder screw revolving speed is 30-40rpm, winding speed 110-
120rpm。
The present invention also provides the PVC coating modification dacron threads that the above method produces, successively by inner core to outer layer
Are as follows: polyester filament inner core, SEBS coat, PVC clad.
PVC coating modification dacron thread of the present invention, wherein polyester filament after SEBS is composite modified, the ultimate strength of yarn and
Elongation at break significantly improves, and solves the problems, such as that polyester filament brittleness is larger.And further improve PVC cladding polyester filament
The defect of common covering property difference, improves product quality.Present invention process method is simple, without adding extras, existing
Having can directly implement on the basis of production line.The PVC coating modification dacron thread produced using method of the invention has color fresh
Gorgeous colour-fast, high-tension, Waterproofing/oilproofing antiultraviolet is ageing-resistant, wear-resistant, and resistance to rot, chemicals-resistant is nontoxic, surface light
The advantages that cunning is nice and cool, long service life, can be widely applied to the products such as carpet, wall paper, beach chair, curtain, seat cushions.
