Description

A kind of production technology of crystal cotton

Technical field:

The present invention relates to fiber filament fields, are especially a kind of production technology of crystal cotton.

Background technique:

Crystal cotton is a kind of using bright yarn as the novel fibre in differentiation of raw material, is the primary raw material of weaving Chenille Yarns, Give a house textile fabric an a kind of thick and solid feeling after weaving, have it is high-grade it is luxurious, soft, that flannelette is plentiful, drapability is good etc. is excellent Point.Crystal cotton is primarily adapted for use in the interior decorations ornaments such as slip cover, bedcover, bed blanket, platform blanket, carpet, wall coverings, curtain curtain, uses Way is extensively.But existing crystal cotton production technology is usually as described in China Patent No. CN106245180A, using there is light flat POY precursor as raw material, precursor is introduced into tow precursor pipe simultaneously by guide frame hanging wire device, keeps tow straight by filar guide It taps into first roller, compressed air network is carried out before first roller, enter back into hot tank and carry out cryogenic tensile deformation, later Enter cooling and shaping after coldplate stretches and enter scroll tube false twisting, makes tow that there is good bulkiness, enter lower hot tank afterwards It carries out shaping, the tow after sizing is sent out by third roller, to spindle position after filar guide finally sufficiently oils on oil tanker Friction roller is wound molding；Its process flow is as follows: the POY precursor for having light flat → tow precursor pipe → network nozzle → the first Roller → upper hot tank → coldplate → scroll tube → second roller → lower hot tank sizing → third roller → wire vent filar guide → oil Take turns → friction roller the coiling and molding that oils.The crystal staple beam of this technique production easily fluffs, due to the bearing of twist arrester when repiece Revolving speed does not catch up with tow speed and is also easy to produce flyings, and monofilament is easily broken off, and the fluffy degree of tow is lacking, and Curl only has 14%, it is difficult to further be promoted.

Summary of the invention:

The technical problem to be solved by the invention is to provide a kind of reduction tow burr, when repiece, will not generate flyings, single The fiber filament Curl of not easy to break, the production technology of the good crystal cotton of tow fluffy degree of silk, production technology preparation is reachable 16%.

The technical solution of the invention is as follows, provides a kind of production technology of crystal cotton, using the POY precursor for having light flat As raw material, it is characterised in that: its process flow is as follows, original silk rack → precursor pipe → pre- network → the first drawing-off godet → at the uniform velocity Threading end bar → upper hot tank → coldplate → scroll tube → the second drawing-off godet → open type master network → auxiliary drawing-off godet → lower heat Case → three rollers of apron formula → oil tanker → coiling and molding → shakes socks, outer inspection → steam box cooks → is packed, wherein three roller of apron formula Godet around wire ring number be 6 circles, increase scroll tube PU disk diameter to 52.5mm to increase the arc of contact of tow and scroll tube And length, drafting multiple 1.72-1.76, upper heater temperature are 198-220 DEG C, lower heater temperature is 165-180 DEG C, winding Power is 8-10g, 150-200 DEG C of steamer temperature, pressure 0.04-0.05MPa, steaming silk time 5-10h.

Preferably, the wind regime of coldplate comes from freeze drier.Stablize air source quality, it is soft.

Preferably, being at the uniform velocity fixed with ceramic draw-off godet on threading end bar, cancel the twist arrester on threading end bar, ceramic draw-off godet There are two, it is evenly spaced at the top of threading end bar and middle part, sets that there are two seal wire slots on ceramic draw-off godet.It avoids flyings and subtracts Few fracture of wire.

The beneficial effects of the present invention are: prior art is improved, first passes through pre- network and enters back into the first drawing-off godet, Burr can be effectively reduced, tow is made to be not easy to fluff, meanwhile, carry out repiece using at the uniform velocity threading end bar when repiece, substitute it is traditional only Twister, tow are not likely to produce flyings, enclose in conjunction with the godet of three roller of apron formula around wire ring number for 6, increase and stretch space, make its drawing It is stretched flat surely, reduces the flat tow plucking phenomenon of more F, to reduce filament stretch fracture, produce flying hair；It is straight to increase scroll tube PU disk Diameter increases the arc of contact and length of tow and scroll tube to 52.5mm, thus when increasing stop of the tow in scroll tube Between, increasing tow fluffy degree, Curl can reach 16% or more, meet the specific richness requirement of Chenille Yarns, and parameter The adjustment of draw ratio improves bulkiness so that being sufficiently tensile, and reduces shrinkage；Winding tension is 8-10g, steamer temperature 150- 200 DEG C, pressure 0.04-0.05MPa keeps spinning cake soft, there is shrink space, has abundant shrinkage.

Specific embodiment:

The invention will be further described With reference to embodiment:

A kind of production technology of crystal cotton, using the POY precursor for having light flat as raw material, it is characterised in that: its technique Process is as follows, original silk rack → precursor pipe → pre- network → the first drawing-off godet → at the uniform velocity threading end bar → upper hot tank → coldplate → vacation Twister → the second drawing-off godet → open type master network → auxiliary drawing-off godet → lower hot tank → three rollers of apron formula → oil tanker → volume Around form → shake socks, outer inspection → steam box cooks → is packed, wherein the godet of three roller of apron formula is 6 circles around wire ring number, is increased false Twister PU disk diameter increases the arc of contact and length of tow and scroll tube to 52.5mm, drafting multiple 1.72-1.76, Upper heater temperature is 198-220 DEG C, and lower heater temperature is 165-180 DEG C, winding tension 8-10g, steamer temperature 150-200 DEG C, pressure 0.04-0.05MPa, steaming silk time 5-10h.In addition, the wind regime of coldplate comes from freeze drier.At the uniform velocity threading end bar On be fixed with ceramic draw-off godet, cancel the twist arrester on threading end bar, there are two ceramic draw-off godets, is evenly spaced in threading end bar Top and middle part, set that there are two seal wire slots on ceramic draw-off godet.It avoids flyings and reduces fracture of wire.

Wherein, by the adjustment to processing step, such as by the successive adjustment of pre- network and the first drawing-off godet, facilitate silk Beam is phozy, reduces burr, meanwhile, using at the uniform velocity threading end bar progress repiece when repiece, traditional twist arrester is substituted, tow is not easy Flyings are generated, is enclosed in conjunction with the godet of three roller of apron formula around wire ring number for 6, three roller of roller formula is improved to three sieve of apron formula It draws, and its godet increases to 6 circles around wire ring number creativeness, increases and stretches space, stretches it steady, reduces more F flat filaments Shu Lamao phenomenon produces flying hair to reduce filament stretch fracture；Increase scroll tube PU disk diameter to 52.5mm to increase silk The arc of contact and length of beam and scroll tube increase tow fluffy degree, volume to increase residence time of the tow in scroll tube Bent elasticity can reach 16% or more, meet the specific richness requirement of Chenille Yarns, and the adjustment of parameter draw ratio, so that filling Divide and stretch, improve bulkiness, reduces shrinkage；Winding tension is 8-10g, 150-200 DEG C of steamer temperature, pressure 0.04- 0.05MPa keeps spinning cake soft, there is shrink space, has abundant shrinkage.
