Description
Technical field
The present invention relates to a kind of modification, particularly the dacron master grain with high hydroscopicity and the method for making thereof of the improvement of the hygroscopic property of trevira about polyster fibre (trevira).
Background technology
Polyester filament of Xiao Shouing and staple fibre in the market, mostly be the trevira of end through modification, its moisture regain under standard conditions only has 0.4%, because it is a hydrophobic fibre, influence the clothes wearing comfortableness, the clothes that particularly wears next to the skin has prodding and itching feeling, feeling of oppression and heat, thereby the human consumer likes pure cotton fabric, more and more dislike synthon, especially the underwear made of trevira.Therefore, how to improve the hydrophilicity of trevira, comfortableness and wholesomeness in the hope of the goods that improve it make it to become a kind of existing stiffness, quick-drying washable advantage, have good hygroscopic textile materials just becoming urgent problem again.
High moisture absorption terylene technology abroad the later stage seventies 20th century just begin, the eighties in 20th century of industrialization is come into operation.China also begins the development research of high moisture absorption polyester resin in the initial stage eighties, and has obtained achievement in research, but these achievements do not obtain widely applying as yet.The method that solves the trevira hydrophilicity at present has: the A chemical process, comprising 1. making the hydrophilization of fiber macromole by copolymerization (grafting or block copolymerization); 2. make the fiber surface hydrophilization by top coat; 3. in fiber, introduce hydrophilic radical with the wetting ability component blend.The B physical method is comprising 1. making fiber surface have vesicular structure; 2. make the fiber surface roughening; 3. fiber cross section heteromorphosis.The purpose of these physical methods is increased fiber specific surface areas, utilizes the suction of micropore capillarity, improves its hydrophilicity.And in actually operating, above-mentioned two class methods of existing independent use, also have with above-mentioned two kinds of methods in conjunction with and usefulness.
With the wetting ability component add in the vibrin, blend melt spinning, again with the hydroaropic substance stripping, make fiber surface form the method for micropore-be stripping method, be efficient ways in above-mentioned all multi-methods that technology also comparative maturity is stable.Japan Supreme Being people company adopts stripping method to produce the high water-absorbent polyester staple of multi-hole type in nineteen eighty-two, and trade name is Wellkey.It is pore former that Japan JP57-193559 adopts ethylene glycol copolymer, and adopting sodium hydroxide is that solvent is made high moisture absorption terylene; It is properties-correcting agent that Japan JP57-161125 adopts the alkyl isophthalic ester, and with its polyester blending spinning, adopting sodium hydroxide is that solvent is made high moisture absorption terylene.
Summary of the invention
The purpose of this invention is to provide a kind of macromolecular material that utilizes as composite additive, and this preparation of composite additives is become high density and dacron master grain with high hydroscopicity resin.With a small amount of this kind dacron master grain with high hydroscopicity and vibrin co-blended spinning, and employing sodium hydroxide be solvent with the stripping of part dacron master grain with high hydroscopicity, promptly can obtain the high moisture absorption polyster fibre that the surface has micropore.
The object of the present invention is achieved like this: it comprises following composition and weight percent: the two hydroxyl ethyl ester resin 50-90% of poly terephthalic acid, the two hydroxy butyl ester resin 50-10% of poly terephthalic acid that contain 1.3 1 dicarboxyl benzene sulfonic acid sodium salts or 1.4 1 dicarboxyl benzene sulfonic acid sodium salts.
Content of the present invention also comprises: can add polyoxyethylene glycol 0-20% as required on the basis of aforementioned proportion; The two hydroxyl ethyl ester resins of poly terephthalic acid that can also on the basis of aforementioned proportion, add 0-40%.
Manufacture method of the present invention is: it is by the two hydroxyl ethyl ester resins of the poly terephthalic acid of 1.3 1 dicarboxyl benzene sulfonic acid sodium salts that drop into by above-mentioned weight percent or 1.4 1 dicarboxyl benzene sulfonic acid sodium salts, the two hydroxyl ethyl ester resins of poly terephthalic acid, the two hydroxy butyl ester resins of poly terephthalic acid, after mixing under 120-140 ℃ of temperature vacuum-drying 4-6 hour, mix with polyoxyethylene glycol again after the cooling; And then through twin screw extruder in fusion under the 240-290 ℃ of temperature, extrude, behind the cooling granulation, can obtain dacron master grain with high hydroscopicity.
During application, the vibrin blended melting spinning tubular fibre with dacron master grain with high hydroscopicity resin 10-30 parts by weight of the present invention and 90-70 parts by weight after the sodium hydroxide stripping is handled, can obtain high moisture absorption polyster fibre again.
Dacron master grain with high hydroscopicity spinning property when co-blended spinning of the present invention's preparation is good, and result of extraction is good, can reach higher hygroscopic property and water retention, simultaneously the static resistance of endowing terylene fiber, pilling resistance, heat retention, dyeability and anti-performance.Master batch of the present invention brings many convenience because its concentration height is convenient to transportation to the user.
