D) join in 85～95 parts of polyester molten masses with 5～15 parts of functional materials, under the high-speed stirred effect, evenly be mixed in the polyester fondant, use the spinnerets of "+" shape irregularly-shaped hole to carry out spinning.
On the basis of the above, optimized technical scheme of the present invention is:
A) with sepiolite, be 1:8 by mass ratio, join mass percent concentration and be in 2% the hydrochloric acid solution, stirred 1 hour, dehydrate, make the activation sepiolite;
B) sepiolite after will activating is 1:5 by mass ratio, joins in the softex kw solution of mass percent concentration 4%, stirs 2.5 hours, and drying makes organic sepiolite;
C) get 2 parts of 0.3 part of ethylene glycol bisthioglycolate glycidyl ether, 1 part of sodium carboxymethylcellulose, 5 parts of Sodium Polyacrylates, 0.1 part of potassium peroxydisulfate and organic sepiolites by mass fraction, 8 parts in water, be under 80 ℃ in temperature, stirring reaction 2 hours, drying obtains the modification functional material that particle diameter is not more than 15 μ m after the grinding;
D) join in 90 parts of polyester molten masses with 10 parts of functional materials, under the high-speed stirred effect, evenly be mixed in the polyester fondant, use the spinnerets of "+" shape irregularly-shaped hole to carry out spinning.
Compared with prior art, advantage of the present invention has: 1) this polyester fiber has high wet absorption and discharging; 2) response time is short, speed is fast; 3) microporeization of fibre structure, heteromorphosis make ventilative, the good hygroscopicity of polyester fiber, and human body comfort is good.
