Description
Technical field
The present invention relates to a kind of core-sheath compound fibre, relate in particular to a kind of antistatic, moisture absorption, dyeable core-skin composite fiber
Background technology
In the processing of chemical fibre class textiles and use, polyamide fiber all can produce electrification phenomenon each other or with other object contact frictions, if electric charge constantly accumulates and fails to eliminate, will cause various electrostatic phenomenons.Static makes polyamide textiles processing difficulties, easily adsorbs dust in the product use, and the electric spark that static produces can set off an explosion and fire.Therefore conduction and antistatic fibre be as the polymer fiber material of a kind of high-tech, high added value, civilian, industry with, decoration with and aspect such as military have extremely important and demand widely.
Antistatic approach commonly used is: (1) pure conduction high polymer fiber, and this fibrid antistatic effect is good, but cost is too high; (2) metal fibre, this fibrid antistatic effect is good, but fabric can not dye, and feel is poor; (3) Polymer Surface carburizing fiber, this kind fabric antistatic effect is good, but fastness to washing and stainability are poor; (4) carbon element conductive fiber, this fibrid antistatic effect is good, but stainability not, cost is higher; (5) composite conducting fiber adds fibrous inside and surface with little molecule antistatic additive, but it exists shortcomings such as lack of homogeneity, fastness to washing are poor, gas permeability difference.
Chinese patent application CN102021670A relates to a kind of conductive sheath-core conjugate fiber and manufacture method thereof, specifically, the component that relates to a kind of cortex is that metal or metal alloy, sandwich layer component are the conductive sheath-core conjugate fiber of thermoplastic polyester, and preparation method thereof.The composite fibre cortex component of this invention and the weight ratio of sandwich layer component are 10/90～30/70, and described metal is selected from indium, tin, polonium, bismuth or cadmium.The metal or metal alloy of this composite fibre cortex improves fiber antistatic behaviour, electric conductivity, shielding property greatly, can be applied in the industry of various high-antistatics, anti-radiation requirement.But its feel is poor, and stainability is poor, and cost is higher.
Adopt the complex of inorganic matter among the Chinese patent application CN1099823A, as sodium hydrogensulfite, sodium thiosulfate, ammonium vanadate, copper sulphate etc., and on-macromolecular organic compound, as quaternary ammonium alkyl chloride, alkylamide halide etc. fabric is handled, make it have antistatic effect, such arrangement type processing mode, the fabric that this kind mode is handled, has antistatic effect preferably at the use initial stage, but this kind fabric is wash resistant not, after repeatedly washing, its antistatic effect also reduces gradually even disappears.
Chinese patent CN101205651B discloses a kind of nano durable antistatic textile, and the fiber in the fiber of composition textiles more than 85% is the epithelium fiber; The nano involucra resin bed that the filament surface recombination of described epithelium fiber is made up of one or more resins in polyurethanes, aziridine, esters of acrylic acid, Carbodiimides, the melamine class, the thickness of this nano involucra resin bed is below the 1500nm, and wherein to contain diameter be the following nano level metal conductive particles of 200nm.Metal conductive particles is one or more in silver, copper, the gold.This kind fabric relative cost is higher.
Summary of the invention
In order to overcome above-mentioned defective, the invention provides a kind of antistatic, moisture absorption, dyeable core-skin composite fiber, this fiber has advantages such as good mechanical strength, hygroscopicity, antistatic behaviour and stainability.
This purpose is achieved through the following technical solutions: a kind of antistatic, moisture absorption, dyeable core-skin composite fiber, and it comprises cortex and sandwich layer, the skin/core mass ratio is that 90/10～10/90(is also referred to as skin/core ratio); Sandwich layer is the fiber that has polyhydroxy or many carboxyls with good moisture pick-up properties, stainability energy and antistatic property; But cortex is the high polymer of melt-spun.
The sandwich layer of a kind of antistatic, moisture absorption of the present invention, dyeable core-skin composite fiber is the fiber that has polyhydroxy or many carboxyls with good moisture pick-up properties, stainability energy and antistatic property, at least a in preferred cotton fiber, bamboo fibre, the flax fibre, further preferred bamboo fibre or flax fibre, most preferably bamboo fibre.
But the cortex of a kind of antistatic, moisture absorption of the present invention, dyeable core-skin composite fiber is the high polymer of other melt-spun, and is at least a in preferred polyethylene terephthalate, High Temperature High Pressure type cation dyeable polyester, boiling dyeing at normal pressure type cation dyeable polyester, boiling dyeing at normal pressure type disperse dye dyeable polyester, polypropylene, polyamide 6 or the polyamide 66; More preferably polyamide 6 or polyamide 66 most preferably are polyamide 6.
The sandwich layer too high levels, though moisture pick-up properties, stainability energy and antistatic property are more excellent, but fibre strength descends, and the operability of spinning process worsens, and the fastness to washing of fabric descends; Sandwich layer content is low excessively, then can not get due moisture absorption, antistatic etc. functional.Emphasis of the present invention has carried out experimental study to the skin/core ratio (mass ratio) of core-sheath compound fibre, and it is 70/30～30/70 o'clock that skin/core ratio (mass ratio) is preferably, and this composite fibre has better antistatic, moisture absorption, stainability energy.Skin/core ratio (mass ratio) more preferably 65/35～40/60 most preferably is 45/55.The specification of this composite fibre and physical and mechanical properties can satisfy the requirement of weaving processing fully.
A kind of antistatic, moisture absorption of the present invention, dyeable core-skin composite fiber can be made as follows: above-mentioned cortex and core material are adopted composite spinning equipment, with 2 screw extruders difference fusion skins, sandwich layer high polymer, high polymer molten is transported to composite spining module extrudes after measuring pump metering, the melt strand cools off, oiling, reeling obtains core-sheath compound fibre after stretching, finalizing the design.
