Description
Technical field
The present invention relates to a kind of blending polyester fiber.
Background technology
Polyester fiber is the maximum synthetic fiber of current garment industry industry use amount, because of its excellent physics, chemical property and the favor of extremely users.Along with the raising of people's living standard, the comfortableness for clothes is had higher requirement.Polyester fiber hydrophily is poor, can not absorb the sweat of skin surface in time, and propose today of requirements at the higher level people to comfortableness, range of application is restricted.And natural fabric is as cotton textiles, although there is good water imbibition, water retention rate is higher, wet guilding is poor, rapid-drying properties is bad, and Application Areas is also restricted.
Making clothing fabric have water-absorbing fast-drying, is the target that people pursue.The hydrophobicity of dacron polyester, the high water retention rate of natural fabric, make a kind of fiber be difficult to take into account water suction, this two attribute of rapid-curing cutback simultaneously.
Chinese patent CN200710019723.6 discloses a kind of water-absorbing fast-drying and produces the method for fabric, using alkali soluble copolymer polyester as pore former, carry out co-blended spinning with fibre-forming polymer and obtain water-absorbing fast-drying fiber, the fabric made is through alkali decrement treatment, fiber surface is made to produce pore, groove, make sweat be absorbed, conduct by capillarity, be diffused into rapidly fabric face volatilization, thus reach water-absorbing fast-drying effect.This product has water-absorbing fast-drying performance, and its measure wicking height reaches 70 ~ 120mm, and water evaporation rate is 85 ~ 95%.
But the fiber that this invention is formed and fabric are when decrement treatment, the stripping property of fiber sheath is better, and the stripping property of internal layer is suppressed, and its moisture sorption effect can not get very big raising.
In addition, compared to thick and heavy solid silk clothes material, light and reach the dress material of heat insulation effect equally, obviously more can bring people comfortable, experience easily.The fabric pursuing light weight is also one of main flow of current Garment Industry.Doughnut has the effect of light weight.
Thus be necessary to develop a kind of tencel simultaneously possessing water suction, rapid-curing cutback, light weight performance, this twice-laid dress material can bring people light, dry and comfortable, comfortable impression.
Summary of the invention
The object of this invention is to provide a kind of blending polyester fiber continuously with through hollow bulb, this fiber to be made after fabric through decrement treatment, can form micro hole construction again, reach the performance of water-absorbing fast-drying, lightweight heat-preserving in fiber.
Technical solution of the present invention is: a kind of blending polyester fiber, containing the conventional polyester A composition of 60 ~ 95 wt%, the solubility polyester B component of 5 ~ 40 wt % in this fiber, and the center of fiber or eccentric position have 1 ~ 3 continuous through hollow bulb, the section of fiber is hollow shape, and hollow rate is 5% ~ 25%.
The center of fiber of the present invention or eccentric position have 1 continuous through hollow bulb, and the section of fiber is hollow shape, and hollow rate is 10% ~ 25%.
In blended fiber of the present invention, conventional polyester A composition is any one in polyethylene terephtalate, polytrimethylene terephthalate PTT, polybutylene terephthalate (PBT) PBT or cation-modified polyester CDP.
In blending polyester fiber of the present invention, alkali soluble copolymer polyester B component is formed by terephthalic acid (TPA), ethylene glycol and M-phthalic acid-5-sulfonate or the combined polymerization of isophthalic acid ester-5-sulfonate; Or formed by terephthalic acid (TPA), ethylene glycol, polyethylene glycol and M-phthalic acid-5-sulfonate or the combined polymerization of isophthalic acid ester-5-sulfonate.
In alkali soluble copolymer polyester B component of the present invention, relative to binary acid total amount, the content of M-phthalic acid-5-sulfonate or isophthalic acid ester-5-sulfonate is 1 ~ 5 mol%, relative to alkali soluble copolymer polyester B component total amount, polyethyleneglycol content is 1 ~ 20 wt%, and preferably molecular weight polyethylene glycol scope is 500 ~ 10000.
The manufacture method of blending polyester fiber of the present invention, comprise following steps: by conventional polyester A composition 60 ~ 95 weight portion, with alkali soluble copolymer polyester B component 5 ~ 40 weight portion, drying respectively, Homogeneous phase mixing, melting, ejection, spinning from the hollow spinneret plate that can generate 1 ~ 3 hollow bulb, to batch, further across deep processing or false twisting processing, obtain the blending polyester fiber that section is hollow shape, hollow rate is 5% ~ 25%.
Blending polyester fiber of the present invention, can be applied in and prepare on water-absorbing fast-drying light weight fibre fabric.Can partly use or all use blending polyester fiber of the present invention, obtained initial fibers, then carries out stripping process by initial stage fabric, removes part alkali soluble copolymer polyester B component, obtains water-absorbing fast-drying light weight fabric.
Stripping process can choose conventional alkali decrement treatment mode, preferably concentration be 1% ~ 5%, bath raio is carry out in the NaOH solution of 100 ~ 200.
Above-mentioned alkali decrement treatment technique adopts common process, and such as, fabric is 1% ~ 5% in concentration, and bath raio is decrement 20 ~ 50min in the NaOH solution of 100 ~ 200, and fabric reduction rate is 10% ~ 30%.By this decrement condition, in fiber, the decrement speed of alkali soluble copolymer polyester B component is 6 ~ 300 times of conventional polyester A composition.
Blending polyester fiber of the present invention, on fiber length direction, has 1 ~ 3 continuous through hollow bulb at center or eccentric position.When the initial stage fabric made carries out stripping process, alkali lye can from the inner surface of the hollow part of fibrous outer surfaces and fibrous inside, and infiltrated fiber makes alkali soluble copolymer polyester B component dissolve, and no matter is dissolution velocity or solute effect, is obtained for larger raising.
Blended fiber after dissolving, in the fibre, on the inner surface of particularly fibrous outer surfaces and internal void, has the minute aperture of circle or ellipse, can see the structure of these minute apertures of fibrous outer surfaces with SEM observation.The capillarity utilizing these minute apertures to produce can make sweat through effects such as wicking, diffusion, transmission, migrates to fabric face rapidly and distributes, thus reaching the object of water-absorbing fast-drying.The inner surface of the hollow part of fibrous inside also has the structure of minute aperture, compared to simple outer surface, there is micro hole construction, there is better wick effect and water evaporation rate.
Blended fiber of the present invention is again doughnut simultaneously, inherently has the characteristic of light weight, and alkali dissolves away part alkali soluble copolymer polyester B component simultaneously, and fabric more light weight is soft, has good feel and snugness of fit.
In the present invention, the water absorbing properties of fabric measures by JIS L1907 A method, as follows:
Fibre water imbibition evaluation method JIS L1907 A method: by the partially submerged water of sample cloth (2 × 25cm) lower end 2cm of vertical hanging, waits for 10min, surveys the height (mm) of liter waterborne, represents absorption speed.
In the present invention, the drying property of fabric adopts the detection method of Shanghai Ke Ken company, as follows:
Fibre drying property evaluation method section cultivates method (0.3 ml): the sample of 10 × 10 cm is arranged in 20 ± 1 DEG C, 24h in the environment of humidity 65 ± 2%, take sample cloth initial weight Wo, 1 cm place above titration mouth of pipe distance sample cloth, instillation 0.3ml water, hang airing, every 5 min claim a weight Wt, until sample cloth is returned to initial weight Wo, record sample cloth water evaporation rate curve over time
Water evaporation rate: (Wt-Wo)/0.3 × 100%.
Fiber hollow rate assay method of the present invention: shoot fiber cross section photo by SEM, after printing, usable floor area instrument, measures hollow space area S
