Description

A kind of manufacture method of wet balance polyester fiber
Technical field
The present invention relates to a kind of manufacture method of wet balance polyester fiber, belong to textile fabric manufacturing technology field.
Background technology
Polyethylene terephthalate (abbreviation PET) is the principal item of polyester, because it possesses higher melt temperature (Tm) and glass transition temperature (Tg), and there is excellent combination property, be widely used in synthetic fibers, bottle piece, The fields such as thin film.Because in PET macromolecular chain structure, hydrophilic radical seldom, leads to its hygroscopicity minimum, if as woven face Material uses, and the regain only 0.4% about of PET leads to its comfort poor, easy balling-up, generation electrostatic, easily adsorbs dust, The shortcomings of cloth cover is easily dirty, affects human body wearing comfort.So, carry out the research of moisture-absorption modified polyester fiber, give it new Characteristic, widens its application, the always focus of researcher research and development.
The domestic at present research and development for moisture absorption type polyester fiber, are concentrated mainly on the following aspects：1) ultra-fine fibre The exploitation of dimension：By developing water-soluble polyester, prepare sea-island fibre with conventional PET composite spinning, then dissolve sea component, preparation Go out that surface area is big, have hygroscopicity and the superfine fibre of preferable comfort；2) method passing through blending and copolymerization：Add tool Have in the inorganic ionss of moisture absorbing or strand and introduce the group with moisture absorbing, to give PET polyester moisture absorbing； 3) exploitation of profiled filament：By profiled filament spinning pack, prepare the fiber (as cross, platypelloid type) of odd-shaped cross section, make It possesses preferable moisture absorption sweat discharging functions.The main application focus of the moisture-absorption modified polyester of exploitation is that textile fabric is led at present Domain.
Sodium bentonite has very strong hygroscopicity and a dilatancy, the water yield of 8～15 times of adsorbable own vol, volume Expansion can reach 30 times, has stronger cation exchange and absorbability；Halloysite nanotubes are by silicon-oxy tetrahedron, alumina octahedral Body forms, and outer wall contains certain silicone hydroxyl, has a stronger absorbability to cation, polar molecule etc., natural nanometer Tubular structure and the property that is easily dispersed so that halloysite nanotubes as a kind of new polymer reinforcing material poly- third It is applied in alkene, epoxy resin, polyethylene, polyamide, polyester, rubber etc.；Diatomaceous density 1.9-2.3g/cm3, heap is close Degree 0.34-0.65g/cm3, specific surface area 40-65m2/g, pore volume 0.45-0.98m, water absorption rate is 2-4 times of own vol, There are fine and smooth, loose, light weight, porous, water absorption and the strong property of permeability, macromolecule polymer material adds a small amount of diatom Soil can significantly improve adsorptivity and the hygroscopicity of material, and can improve the heat-resisting, insulation of product, aging resistance etc. and act on.Gather to benzene Because methylene based structures exist in naphthalate (PTT) molecule, its lattice bulk density is less than PET, has more preferably saturating Lightness, thermostability and processability.
It is a kind of conventional method by the hygroscopicity that the method for copolymerized grafting improves polyester fiber, patent " a kind of polyester, Its preparation method and the middle M-phthalic acid being used containing sulfonic acid group of polyester fiber (CN 104788664A) or derivatives thereof conduct 3rd body is simultaneously carried out termination process and is prepared modified copolyester using one or more of polytetramethylene glycol, polypropylene glycol, and this changes The hydroscopicity highest of property copolyesters only reaches 2.5%.This stable preparation process is poor, and the measuring equipment requirement of production is higher, It is difficult to large-scale production.
