Abstract
The invention discloses a new hydrophile fast drying fiber and a method of production and knitting, the hydrophile fast drying fiber in alkali weight reduction treatment is produced by blend spinning 5-30wt% kali-soluble copolyester as pore-forming agent and 95-70wt% polymer-forming fiber. The invention has a good hydrophile fast drying performance, wherein the wicking height is 70-120 mm, and the evaporation rate of water is 85-95%.
Description
Technical field:
The present invention relates to a kind of polyester fiber and production method.
Background technology:
Terylene is as one of the big main force of three in synthetic fiber fiber, because of its good physics and chemical characteristic are widely used in garment surface and non-garment industry.Since dacron product comes out, also once all kinds of textiless had been weaved by downstream user as main textile raw material so that its drapability is good, intensity is high.But because its hydrophobic property and being restricted in the Application for Field that water imbibition or hygroscopicity are had relatively high expectations.Though and natural fabric has good water imbibition as textile, because of its water retention rate is very high, wet transmitting performance is relatively poor, and range of application also has been subjected to restriction.A kind of fiber is had simultaneously absorb water-lead wet high-comfort can be the target that present many fiber research persons and fiber production producer lay siege to.
Along with the variation of everyday general purpose and personalized and, carried out various trials and had premium properties, for example water absorbing capacity, wet ability etc. thoroughly in the hope of reaching natural fabric for making high-grade daily clothes.The fabric that now also has the quick-drying energy except the water imbibition height is applied at some high-grade sportswears, so that sportswear when wearing, can keep comfortable, can wear state.
Following clothing will develop towards comfortable, healthy direction with fabric, and the water-absorbing fast-drying fabric is exactly one of important indicator wherein.Here " water-absorbing fast-drying " is to instigate not hydrophilic fabric to have water imbibition and rapid-drying properties simultaneously, and in general, natural fabric still is that synthetic fiber all are difficult to take into account this two kinds of performances.But the water-absorbing fast-drying process technology can be accomplished this point.Water-absorbing fast-drying fiber is that the capillarity of utilizing the fiber surface minute groove to produce makes sweat through effects such as wicking, diffusion, transmission, migrates to fabric face rapidly and distributes, thereby reach the purpose of water-absorbing fast-drying.Water-absorbing fast-drying fiber be conceived to absorb water, the functional fibre of rapid-curing cutback characteristic and clothes comfortableness.
The section overwhelming majority of water-absorbing fast-drying fiber is trilobal, cross-like shape at present.Because the angle that forms between cross four limits has the capillary channel effect, so this fiber has the moisture transported permeable performance of a bit.But the water absorbing properties that this fiber produced can't satisfy client's requirement sometimes, needs even more ideal wicking function.
Alkali soluble polyester (COPET) is the PET copolymer that has added the 3rd component.At first in the polyester molecule chain, introduce sulfonate groups,, have sucting electronic effect, changed the regularity of polyester molecule chain simultaneously, help the infiltration of water and the carrying out of the molten process of alkali because sulfonate groups is the polarity hydrophilic radical.But, influence spinnability because the formed sterically hindered and polar effect of sulfonate groups causes melt viscosity sharply to rise.Therefore keeping introducing soft segment under the alkali-soluble prerequisite of polymer, improve the rigidity of the molecule of polymer greatly, improve the spinnability of polymer, further improve the alkali solubility of polymer simultaneously.
Summary of the invention:
The object of the present invention is to provide the method for the good novel water-absorbing fast-drying fiber of a kind of water-absorbing fast-drying performance and production method and production fabric.
Technical solution of the present invention is:
A kind of novel water-absorbing fast-drying fiber is characterized in that: be with 5wt%～30wt% alkali solubility copolyesters as pore former, carry out the product that co-blended spinning makes with 95wt%～70wt% fibre-forming polymer.
The fibre-forming polymer of fiber is any one in polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate (PBT), the cation dye chromophil polyester.
Main repetitive as the alkali solubility copolyesters of pore former is an ethylene glycol terephthalate, wherein contains copolymer polyethylene glycol 20～30wt%, 5-sodium sulfonate-ethylene isophthalate 1.5～4.5mol%.
The cross section of fiber is any one in circle, cross, the circle/cross.
A kind of production method of novel water-absorbing fast-drying fiber is characterized in that: comprise the following steps:
(1) blend: with percentage by weight is that the alkali solubility copolyesters of 5wt%～30wt% and the fibre-forming polymer of 95wt%～70wt% carry out blend before fusion;
(2) spinning: polymer blend is abundant melting mixing in screw rod and casing pipe arrangement, carries out spinning through measuring pump, filament spinning component, gets novel water-absorbing fast-drying fiber.
A kind of novel water-absorbing fast-drying fiber is produced the method for fabric, and it is characterized in that: novel water-absorbing fast-drying fiber is woven into fabric, and gets product through the alkali decrement treatment, reduction rate is controlled at 10%～30%.
The alkali decrement treatment be 1%～5% in concentration, bath raio is to carry out in 100～200 the NaOH solution.
Above-mentioned alkali decrement treatment process using common process gets final product, and for example, fabric is 1%～5% in concentration, and bath raio is decrement 20～50min in 100～200 the NaOH solution, and the fabric reduction rate is 10%～30%.By this decrement condition, the decrement speed of fiber pore former is 6～300 times of fibre-forming polymer.Fabric after the alkali decrement carries out SEM observation, and fiber surface has pit clearly.These pits have been given the performance of water absorption of fabrics rapid-curing cutback.
The production technology that the present invention adopts is simple, easy to operate, can make the fiber of gained have good water-absorbing fast-drying performance.
The invention will be further described below in conjunction with drawings and Examples.
