Abstract
This invention discloses one Hollow polybutylene terephthalate fiber fabrics, the proportion of fiber in the fabrics is 0.79 to 1.2 g / cm 3 .The method is that mix the polybutylene terephthalate and soluble polyethylene terephthalate, blend by mixing Machine, winding through spinning, produce the long silk, form the soluble the formation fabric in the NaOH solution to get the fiber braiding of hollow polybutylene terephthalate. This invention use the water soluble COPET as Dao component, PBT polyester as Hai component, the processed fabric is treated in the alkali solution to get rid of the COPET in Dao component, so the PBT fiber contains the hole which size below 1000nm. Compared to other normal fabric with PBT fiber, the fabric in this invention not only keeps all the original features, but also has the characters of warm, washing-available, thin, soft, breathable. The method in this invention is simple and easy to manipulate.
Description
Technical field:
The present invention relates to a kind of polybutylene terephthalate (PBT) fiber (being the PBT fiber) fabric and manufacture method.
Background technology:
Polybutylene terephthalate (PBT) fiber (being the PBT fiber) and goods thereof are soft, and hygroscopicity ABRASION RESISTANCE and fiber crimp are good, and the tensile elasticity and the elasticity of compression are fabulous, and its elastic recovery is better than terylene.The PBT fiber all has special retractility under dried hygrometric state condition, and the elasticity influence that not changed by ambient humidity, and price is far below spandex fibre.The PBT fiber also has good dyeability, and available common DISPERSE DYES is carried out boiling dyeing at normal pressure, and need not carrier.It is bright-coloured to dye the back fiber colour, and COLOR FASTNESS and chlorine resistance thereof are good.
Because the PBT fiber has more above-mentioned characteristics, is subjected to the common concern of textile industry in recent years, obtained using widely in every field.Be specially adapted to make swimsuit, tights, training clothes, gym outfit, the contour elasticity textile product of using in the medical treatment of bandage.
And the composite fibre of PBT is better comfortable with it, and performances such as gloss and adsorptivity enjoy people's attention, can be widely used in clothes, dermatine, and construction material, filtering materials etc. become 21 century one of the most promising fiber.
Yet, any fiber, if constitute the words of fiber by single polymer, its performance must be subjected to certain restriction, single PBT fabric warming, can wash, have shortcoming aspect frivolous, soft, the permeability, so special composite fibre research is had more certain future.
Summary of the invention:
The object of the present invention is to provide a kind of characteristic that had both had the PBT fiber, have simultaneously excellent warming, can wash, the hollow polybutylene terephthalate (PBT) fabric and the production method of frivolous, soft, permeability.
Technical solution of the present invention is:
A kind of hollow polybutylene terephthalate (PBT) fabric is characterized in that: the fiber proportion in the fabric be 0.79～1.2 the gram/every cubic centimetre.
In the fiber cross section, the area in hole accounts for 10～40%.
On the fiber cross section, the hole is circular.
Hole in the fibre single thread is a blind hole, and on the cross section of monofilament, hole count is 3～100 or more.
In the fibre single thread, diameter is that the pore of 5～1000nm accounts for 98～99.9%, and all the other are the above pore of diameter 1000nm.
Fibre number is 40～300dtex, and the diameter of monofilament is 10～25 microns.
Fibre strength is more than the 2.0cN/dtex, and degree of stretching is 40～80%, and shrinkage factor 8～16% is being dyed rate 70～90%, and bar evenness is 0.1～5%.
A kind of production method of hollow polybutylene terephthalate (PBT) fabric, it is characterized in that: comprise the following steps: polybutylene terephthalate (PBT) is mixed with water-soluble poly ethylene glycol terephthalate (being COPET), by the muller blend, through spinning silk winding, make the DTY long filament again, weave into behind the fabric through the dissolution process of NaOH solution, obtain hollow polybutylene terephthalate (PBT) fibrous braid.
The weight ratio of polybutylene terephthalate (PBT) and water-soluble poly ethylene glycol terephthalate is 60～90: 40～10 in the proportioning raw materials.
Polybutylene terephthalate (PBT) and the water-soluble poly ethylene glycol terephthalate rate of dissolution in aqueous slkali is than being polybutylene terephthalate (PBT): water-soluble poly ethylene glycol terephthalate=1: 80～1: 200.
The present invention cuts into slices with water-soluble COPET and makes island component, the PBT polyester slice is made sea component, the fabric that processes is through the processing of aqueous slkali, remove the COPET of island component, contain the following pore of 1000nm in such PBT fiber, not only kept all characteristics of original PBT fiber, also more have warming compared with the fabric of general PBT fiber, can wash, frivolous, softness, characteristics such as ventilative.Production method is simple, and is easy to operate.
The invention will be further described below in conjunction with embodiment.
The specific embodiment:
