Description
Technical field
It is the present invention relates to synthetic fibers production technical field, in particular to a kind of highly hygroscopic to perspire rich font nylon elastic
Silk.
Background technique
With warming for global climate, China's spring and summer temperature based on damp and hot weather, people to the moisture absorbing and sweat releasing of dress ornament,
Permeability has higher requirements, so garment material product must have frivolous, ventilative feature.Moisture absorbing and sweat releasing class textile fabric
Primary efficacy be: absorbing sweat, quick-drying, easy to wash, non-ironing, in summer and high temperature and humidity, use refrigerant can relax to people is a kind of
Suitable wearing feeling.So it is widely used in underwear, coat, shirt, easy dress, gym suit, especially related to movement
Its application prospect of field it is quite wide.The elastic filament raw materials market demand of current frivolous nylon fabric is larger, nylon stretch yarn
It is mainly used in machine packet.Therefore, develop it is highly hygroscopic perspire rich font nylon stretch yarn product and gear to actual circumstances very much, meet client's
Demand.
Summary of the invention
The purpose of the present invention is to provide it is a kind of it is highly hygroscopic perspire rich font nylon stretch yarn, there is the highly hygroscopic spy perspired
Special effect fruit, the conventional nylon stretch yarn product compared in summer clothes raw materials market have biggish competitive advantage, Neng Gouchuan
Make more economic benefits.
The technical solution adopted by the present invention to solve the technical problems is:
One kind is highly hygroscopic to perspire rich font nylon stretch yarn, is prepared by following steps:
(1) melting high-speed spinning: slices of caprone (relative viscosity 2.45 ± 0.03 of slices of caprone, moisture content≤0.06wt%) is thrown
Enter in screw extruder and melt uniformly, screw extruder temperature of each section is set between 250-270 DEG C, and spinning temperature is
260-265 DEG C, melt sprays to form melt stream by the spinneret orifice of spinning pack, and the cross-sectional shape of the spinneret orifice is rich
Font；
(2) be cooled and shaped: melt stream is cooled into as-spun fibre through cross air blasting；
(3) oiling cluster: as-spun fibre forms tow through oil nozzle oiling cluster；
(4) wind: then tow is wound through pre- Network device, draw-off godet, master network device, obtain rich font POY long filament；
(5) seal wire heats: in RPR plus playing in equipment, extremely through seal wire, the first roller for feeding silk, twist arrester by rich font POY long filament
Heater box, heating temperature are 168-172 DEG C；
(6) cooling false twisting: it is cooling through coldplate after rich font POY long filament heating, false twisting is carried out into scroll tube；
(7) drawing-off: by after false twisting, rich font POY long filament enters the second roller and carries out drawing-off, and drafting multiple is in 1.23-
Between 1.28；
(8) wind: tow enters winding area winding by yarn cutter, filar guide, oiling roller, obtains product.
The spinneret section of conventional polyamide fibre melt spinning is with round in the majority, and this product is in spinning production by spinneret spinneret
The circular cross-section in hole is adjusted to rich shaped sections.The section for developing matched spinning and draft process production is rich font polyamide fibre bullet
Power silk product, the cross section with class " rich " character form structure, thus the degree of profile (namely degree of irregularity) of fiber is increased, and
Since the outer profile of class " rich " character form structure has groove, capillary effect is enhanced, fiber is enable to absorb skin table rapidly
The moisture and sweat in face by spreading, being transmitted to outer layer, thus have stronger moisture absorbing and sweat releasing ability.Utilize cutting for rich font
Face fiber can overcome the limitation of natural fiber, so that the snugness of fit of dress ornament improves a lot.
For cooperation produce it is highly hygroscopic perspire rich font nylon stretch yarn, the production equipment of POY must redesign, spinneret
Plate must be changed to rich font hole spinneret.Other than matched hardware device, the selection of raw material is also extremely important, because of production
Porous chinlon POY silk flow during spinning is smaller, it is necessary to improve flow velocity it is slow and caused by heat deterioration phenomenon.Secondly
Since fine-titred fibre bundle is more sensitive, the precision requirement of spinning pump and oil agent metering pump can produce commonly than originally
Specification requirement it is more stringent, matched supplementary material is also that opposite promotion is done on original quality base, be can be only achieved
The requirement of production is refined, in addition the texturing process in rear road must properly adjust production technology, keep the different of fiber to greatest extent
Shape degree.
The screw pressure of screw extruder is 120-125kg/cm in step (1)2, screw speed 45-50r/min.
The spinning speed of step (1) high speed spinning is 4200-4300m/min.
Rich font includes "-" type seam in step (1), and "-" type sews on interval same distance four pairs of semicircles pair of arrangement, semicircle
Pair two semicircles using "-" type seam as axis setting symmetrical above and below, the width of "-" type seam is 0.2-0.4mm, and the radius of semicircle is
0.5-0.8mm, the spacing distance of adjacent semicircle pair are 0.8-1mm.
The parameter setting of side-blown air cooling in step (2) are as follows: 16-18 DEG C of wind-warm syndrome, relative humidity 95-98%, wind speed 0.45-
0.5m/s。
The nylon oiling agent pure water lotion that the finish used that oils in step (3) is 6%, the conductivity of pure water is in 0.4-0.6 μ s/
Between cm, oil applying rate 0.6-0.7%.
Winding speed is 4200-4300m/min in step (4).
False stranding device friction disk uses PU disk, specification 6mm in step (6), and frictional disk group is combined into 1-7-1, and D/Y ratio is set as
1.55-1.60.PU disk is used to reduce false twist tension, reduces lousiness, increases intensity.
Second roller revolving speed described in step (7) is 650-680m/min.
Winding speed is 600-630m/min in step (8).
The beneficial effects of the present invention are: having the highly hygroscopic special-effect perspired, compare in summer clothes raw materials market
Conventional nylon stretch yarn product have biggish competitive advantage, more economic benefits can be created.
