Description
Technical field
The present invention relates to a kind X-type and lead wet moisturizing coloured polyester POY fiber and manufacture method thereof.
Background technology
POY: preoriented yarn, full name: PRE-ORIENTED YARN or PARTIALLY
ORIENTED YARN.Refer to through high speed spinning obtain the degree of orientation between non-oriented silk and drawn yarn not
The chemical-fibres filaments being completely stretched.Compared with undrawn yarn, it has a certain degree of orientation, good stability,
Often it is used as the special silk of draw false twisting textured filament (DTY).
According to the Morphologic Characteristics of chemical fibre, generally fall into long filament (Continuous filament) and short fibre
The dimension big class of (staple fibre) two.Long filament in chemical fibre manufacture process, spin fluid (melt or solution)
After spinning technique and post-treatment operation, the length obtained fiber in terms of km is referred to as chemical fiber filament.
Chemical-fibres filaments can be divided into monofilament (Monofils), multifilament (Multi-filament), twisted filament, retwist silk, cord silk
With textured filament (Textured filament), POY fiber belongs to the one of polyester filament.
At present, although the portion of techniques of China's polyester fiber industry and product are reached advanced world standards, but
Also being faced with such as that high added value functional fiber kind is few simultaneously, yield poorly, quality is the highest, and homogeneity is competing
Strive fierceness, the outstanding problems such as industrial profit rate is low.Owing to chemical fibre and textile product are in functionalization, comfortable
All there are respective pluses and minuses in the characteristic aspects such as property, it is impossible to meets people to natural, comfortable, attractive in appearance, green
The fashion demand of environment protection health.Therefore, all kinds of various super emulation, functional and biomass fiber material are researched and developed
Such as antibacterial, deodorant, promotion microcirculation in human body etc., it is increasingly becoming the weight of various countries' chemical fiber factory new product development
Point, from the nineties in last century so far, Japan of Japan spins the y-shaped cross-section succeeded in developing and carrys out wet dissipation.
For POY fiber, the most domestic it is primarily present following patent documentation:
Patent publication No.: CN101435113, it is provided that one is washed by recycled PET bottles sheet stock large-scale production
The method of synthetic fibre POY long filament, is ground into the bottle chips of lamellar by the waste PET bottle of recovery, cleans post-drying,
It is then fed into crystallizing bed internal, under the hot wind action entering crystallization bed body, crystallizes, bottle chips table
Face forms crystallizing layer, then bottle chips is sent into drying tower and is dried, and dried bottle chips enters screw rod
Extruder carries out melt extruded, after the melt feeding dual stage filter apparatus of gained being filtered, enters spinning
Case, uses high-speed spinning process to carry out spinning, prepares terylene POY filament.This production terylene POY filament
Method, have employed fill-type drying mode, uniform drying, operating cost is low；Drying tower is provided with
Spiral agitator, solves the problem that recycled PET bottles sheet stock occurs " bridging " in dry run；Use
Two-stage filter, it is ensured that filter quality.This just can with serialization, producing terylene POY filament in scale this
One high-end product.But, the polyester that this patent is used is single PET polyester, it is difficult to avoid single poly-
Defect existing for ester fiber.
Summary of the invention
For solving the problem of above-mentioned existence, it is an object of the invention to provide a kind X-type, to lead wet moisturizing coloured
Polyester POY fiber and manufacture method thereof, described POY fiber be not greatly reduced terylene physical and mechanical properties
With carry out physical and chemical modified under conditions of textile process performance, overcome that polyester derivative is wet, moisturizing is poor, dress
The most next to the skin, there is feeling of oppression and heat, affect attractive in appearance and comfortableness, retain natural fiber and there is moisture absorption, warming, alkaline-resisting
It is not likely to produce electrostatic, soft comfortable, the endurable feature such as washable.
For reaching above-mentioned purpose, the technical scheme is that
One kind X-type leads wet moisturizing coloured polyester POY fiber, and described fiber is by polyester fiber and polyhydric alcohol
After blending and modifying, melt spinning is formed, and described fiber includes the composition of following weight portion: polyester fiber:

Cooling and solidifying, Xu Leng temperature is 110～120 DEG C, and cross air blasting wind speed is 0.2～0.5m/s, and pathogenic wind-warm is
15～20 DEG C, through oiling, pre-network, coiling and molding, winding speed controls 500～800m/min, prepares
Described novelty artificial toothed oak silk fiber.
Separately, described class X-type leads wet moisturizing coloured polyester POY fibrous fracture intensity >=3.45cN/dtex, and fracture is stretched
Long rate >=20%.
The beneficial effects of the present invention is:
Described POY fiber is not under conditions of being greatly reduced terylene physical and mechanical properties and textile process performance
Carry out physical and chemical modified, overcome that polyester derivative is wet, moisturizing is poor, wear the most next to the skin, have feeling of oppression and heat, impact
Attractive in appearance and comfortableness, retains natural fiber and has moisture absorption, warming, alkaline-resisting is not likely to produce electrostatic, soft relaxes
The feature such as washable suitable, endurable, in fiber surface morphology performance and functionally to surmount other moisture absorbing and sweat releasings in the past
Product, it is important that the solution that a little seeks to lead wet dehumidifying moisturizing problem, this is because a kind of fiber or one piece
The regain of fabric can not be the highest or the lowest, because Tai Gao or the lowest the most easily affects its comfortableness, namely
There is the dynamic equilibrium of excellent hot wet migration energy, make the class X-type of this Project-developing lead wet moisturizing coloured poly-
Ester POY fiber should retain the feature of polyester fiber and natural fiber, overcomes natural fiber and polyester again
The defect of " the general character shortcoming " of fiber, has and leads wet, moisturizing, the anti-fuzz balls of antistatic, soft bulk, light
Pool is soft, take the good characteristic such as be unlikely to deform comfortable, well-pressed, even surmounts in terms of some combination property
The natural quality of natural fiber, to property such as high-performance, multi-functional, differential, comfortableness, Safety and Environmental Protections
Can aspect development.
Use polyester profiled cross section abnormal shape spinning (quaterfoil shape cross section) and rough surface microporous skill
Art, while keeping fiber to lead wet moisturizing and improve fiber gloss, improves the uvioresistant function of fiber.Logical
Cross the application of the Industry Promotion to this project, effectively digest domestic existing normal polyester production capacity and alleviation is spun
Knit the raw material demand to natural fiber, be expected to alleviate China current polyester dacron industry homogeneity competition serious,
The present situation that added value of product is low, changes the simple fabric of conventional, lacks fabric specific functionalities target
Research, promotes product to develop to diversification, superior and high additive value direction, for research and development class X-type
Lead wet moisturizing coloured polyester POY fiber and new approaches are provided.
Research uses the most steady of the accurate controlled system of polyhydric alcohol blending and modifying, cross section abnormal shape and high degree of profile
Determine spinning technique process technology and prepare polyester fiber.Research class X-type leads wet moisturizing coloured polyester POY fiber
Aggregation has stronger leads wet moisturizing differential capillary effect.By changing fibre section form abnormal shape and face
Expect that rough surface is indulged surface at fiber and formed groove, utilize this groove to carry out the capillary tube in reinforced fabric
Wicking and moisture absorption ability.
Described class X-type leads wet moisturizing coloured polyester POY fibrous fracture intensity >=3.45cN/dtex, extension at break
Rate >=20%.
