It is reported to have the profiled filament of moisture absorption sweat discharging functions, the cross section of fiber is all fluted.As " Coolmax " polyester fiber that du pont company is produced, its cross section becomes unique flat cross, and fiber surface is vertically forming four grooves, has to have more 20% surface area than general fiber, and its moisture absorption sweat discharging functions is better than other allied fiber.The emerging limited company that weaves produces in the Taiwan " Coolplus " is by Y shape and star section equally, utilizes the fiber surface minute groove to produce capillarity, makes sweat wicking, diffusion, volatilization.The H type end side PET hygroscopic fibre (commodity are called EASTLENE) of Far East textiles company and " Topcool " hygroscopic fibre of the said firm have good wicking, can breathe, do soon, sticking characteristic such as take.
Odd-shaped cross section hygroscopic fibre in the market all is staple fibre yarn, low-stretch yarn and the full-drawn yarn (FDY, DT) of all size.The characteristics that the rigidity of polyster fibre is big, fabric is very scraped have been well known fact, when the odd-shaped cross section of many grooves is given the dry and comfortable characteristic of fabric moisture, have also given prominence to the inherent defect of polyster fibre, make the feel of fabric more coarse, stiffening.Because hygroscopic fibre must be made underwear or be used for its good moisture absorption function of a fabric competence exertion next to the shin, the soft feel of fabric next to the shin is undoubtedly another important indicator of comfort property, and the flexibility that existing hygroscopic fibre production technology does not all have how to improve fabric is included in the research.
Summary of the invention
The objective of the invention is to improve the existing coarse stiffening feel of moisture absorbing and sweat releasing fabric, a kind of production method with hygroscopic fibre of improved flexibility energy is provided, the fabric that utilizes this fiber to make, its comfort property improves a lot.
Purpose of the present invention is achieved through the following technical solutions:
The production method of hygroscopic fibre, it is characterized in that: polyester fondant is through being installed on the profiled-cross-section spinnerets spray silk in the spinning manifold, carry out slow cooling heating, lateral blowing then, oil, reel through 4800～10000m/min ultrahigh speed again, make hygroscopic fibre.
Further, in the production method of above-mentioned hygroscopic fibre, the temperature of described spinning manifold is that 280～300 ℃, the temperature of slow cooling heating are 270～290 ℃, and the temperature of lateral blowing is 20～26 ℃, and the wind speed of lateral blowing is 0.30～0.85m/s.
Further, in the production method of above-mentioned hygroscopic fibre, described profiled-cross-section spinnerets be have that wicking, quick-drying function, vertical table mask fluted spinnerets, especially cross section are Y-shaped, 3T shape, cross, H shape, five leaf or ninth of the ten Heavenly Stems word shape spinnerets.
Again further, in the production method of above-mentioned hygroscopic fibre, described polyester fondant directly comes the final polycondensation reactor of autopolyester synthesis phase; Also can be by polyester slice through after pre-crystallization and the dried, extrude and the melt that forms through screw extruder, the operating temperature of described screw extruder is 260～300 ℃.
The present invention is extruded into melt with the normal polyester section through screw extruder, perhaps directly uses the polyester fondant that forms after the polymerisation, by the profiled-cross-section spinnerets, utilizes the super high-speed spinning technology to produce different section type hygroscopic fibre (HOY).This HOY silk has odd-shaped cross section and the groove identical with hygroscopic fibre of the same type, thereby has kept the dry and comfortable characteristic of good moisture absorption that similar hygroscopic fibre had; Simultaneously, owing to adopt the super high-speed spinning winding process, the supramolecular structure of the HOY silk that forms obviously is different from fibers such as traditional polyester DTY, FDY, DT, the fabrics feel soft that adopts the HOY silk to make, significantly better than the fabric of producing with hygroscopic fibres such as similar polyester DTY, FDY, DT, improve the coarse stiffening feel of existing moisture absorbing and sweat releasing fabric, improved the soft comfort property that promotes this kind fabric.The present invention can utilize existing high-speed spinning equipment to produce, and technical process is simple, production efficiency height, stable.
The specific embodiment
Be that example is described further technical solution of the present invention to adopt the normal polyester section to be extruded into melt below through screw extruder.
Adopt normal polyester (PET) section, utilize the profiled-cross-section spinnerets, adopt the super high-speed spinning processing technology routine, drawn is not produced hygroscopic fibre HOY silk.Technological process is: PET section → drying → screw extruder → spinning → slow cooling heat block → lateral blowing cools off → oils → ultrahigh speed coiling → profiled-cross-section moisture absorbing and sweat releasing HOY silk.
The spinnerets cross section can be " Y " shape, " 3T " shape, " ninth of the ten Heavenly Stems " font, " ten " font, " H " shape, " five leaves " shape etc. among the present invention, also can be other shape with wicking, quick-drying function, the fluted profiled fibre of vertical table mask.
Enter screw extruder, 260～300 ℃ of extruder temperature, 280～300 ℃ of spinning manifold melt temperatures through pre-crystallization, dried section, 270～290 ℃ of slow cooling heat block temperature, 20～23 ℃ of lateral blowing temperature, side-blown wind speed 0.45～0.65m/s, spinning speed 4800～10000m/min.Spinning technology parameter can be adjusted according to different size, the different cross section shape of distinct device, fiber, general dried section is moisture can satisfy spinning requirement about 20ppm, low more good more, the cross section special-shaped degree of fiber is between 20～60%, degree of profile is lower than 20%, is difficult to guarantee the moisture absorbing and sweat releasing performance of fabric, is higher than 60%, easily broken end is difficult to normal winding.
Because it is high that HOY spins speed, oriented crystallineization takes place in the spinning process, the unformed shape of local orientation is very fast crystallization in the melt-spun process, so crystal degree of perfection height that forms, crystalline region degree of orientation height, crystallite dimension is big, correspondingly in the crystalline region between crystalline particle the slit bigger, promptly the amorphous region size increases greatly.Existing research data shows, the degree of orientation of ultra-high-speed spinning fiber amorphous region is low more than other, the composite bending modulus of fiber is lower, the feel that shows as fiber on the macroscopic view improves greatly than the pliability that low speed of the same type spins (FDY, DT, staple fibre yarn, DTY) fiber, thereby improve the soft degree that promotes fabric, improved the soft comfort property of moisture absorbing and sweat releasing fabric.
The wicking that the moisture absorbing and sweat releasing HOY fiber that the present invention produces is had, do pleasant performance and soft hand feeling soon and illustrate with the following example:
The DTY of same specification (83dt/36f), same cross section (" ninth of the ten Heavenly Stems " font) and the fabric that two kinds of hygroscopic fibres of HOY are made into same institutional framework are carried out testing its moisture absorbing and sweat releasing performance and softness after same dyeing and finishing technology is handled, concrete data such as following table 1 and table 2.The cross section degree of profile of two kinds of fibers is approaching, and its capillary height and moisture content are more or less the same, and illustrate that its moisture absorbing and sweat releasing performance is similar, and suspended coefficient differs greatly, and illustrates that the fabric sofetening degree that the HOY fiber is made into really is greatly improved.
