The present invention compared with prior art has tangible advantage and beneficial effect.By above technical scheme as can be known, in order to reach aforementioned goal of the invention, major technique of the present invention thes contents are as follows:
The invention provides a kind of upgrading polyester fiber, be to be principal component unit repeatedly, and (wherein R is selected from the alkyl of carbon number 3 to 30, the aromatic radical and the alkylaryl of carbon number 7 to 40 to contain the organic sulfonate RSO3M that following formula A represents by 85 moles of above ethylene glycol terephthalates of %; M is alkali metal, alkaline-earth metal) polyester that forms of the poly-alkylene glycols composition of composition and B, through spinning and fiber, and satisfy following three conditions:
(1), the content of above-mentioned A composition RSO3M is 0.4～5 weight %;
(2), the content of above-mentioned B one-tenth segregation alkylene glycols is 0.4～5 weight %;
(3), through spinning and above-mentioned polyester fiber carry out the decrement processed with the alkaline solution of concentration 0.2～8 weight % in 60～130 ℃, reduction rate 5～45 weight %, dye, making and forming single fiber at fiber surface is the superfine filoplume of 0.1 to 0.001 red Buddhist nun.
Manufacture method as for the upgrading polyester fiber relevant with the present invention, be to be the polyester of principal component with the polyethylene terephthalate, before esterification to polymerisation finishes, the poly-alkylene glycols that adds the organic sulfonate and the B composition of above-mentioned A composition, get the polyester of desired molecule amount through polymerization, make fiber via extruder melt spinning, extension.The fiber of gained, carry out the decrement processed with alkaline solution, the fiber surface local segmentation is become the thinner fiber of most fiber numbers, dye then, pass through the mechanical shock strength of current in the dyeing and finishing process, can further deepen the fine degree of branch, at the fiber surface filoplume that to form most single fiber fiber numbers be 0.1～0.001 red Buddhist nun.
The manufacture method of the upgrading polyester fiber relevant with the present invention, the molecule that is characterized as the long-chain shape of wherein crucial additive A, two kinds of compositions of B.The organic sulfonate of A composition is not possess ester formation property functional group, and evenly has fibrous inside with dispersity.In the process that fibre spinning is extended, organic sulfonate is straightened into rectangular monomolecular form because of the effect of shearing force, and parallel fibers is axial, is uniformly distributed in fibrous inside.In follow-up decrement process, above-mentioned be straightened, be parallel to fiber axis to the organic sulfonic acid molecules of salt be dissolved, so fiber is divided into thinner fiber filoplume.The fiber filoplume that this kind is very thin has uneven fiber number and uneven length, therefore has the feel of extremely soft, dry and comfortable and similar natural fabric.Though B becomes the segregation alkylene glycols to possess ester formation property functional group, the part for polymerization in fiber is few, and major part exists in the fiber in homodisperse mode.This poly-alkylene glycols helps the dispersion of organic sulfonic acid molecules of salt in fiber, therefore can further strengthen the effect of cutting apart fiber.
The manufacture method of the upgrading polyester fiber relevant with the present invention, what wherein (A) formula was represented is organic sulfonate, it specifically comprises: the mixture of sodium salt, lithium salts, sylvite, calcium salt and the nonyl benzene sulfonic acid of propyl sulfonic acid, butyl sulfonic acid, amyl group sulfonic acid, hexyl sulfonic acid, heptyl sulfonic acid, octyl group sulfonic acid, nonyl sulfonic acid, decyl sulfonic acid, the cool basic sulfonic acid of lauryl sulfonic acid, Rou Beans, palmityl sulfonic acid, hard ester group sulfonic acid etc., sodium salt, lithium salts, sylvite, calcium salt and the above organic sulfonate of lauryl benzene sulfonic acid.Organic sulfonate used in the present invention is not required to be single compound, and the mixture of the organic sulfonate in the above-mentioned example also can use, to effect of the present invention and have no adverse effects.The addition of organic sulfonate is 0.4～5.0 weight % among the present invention.Addition is during less than 0.4 weight %, and the effect of being reached is also not obvious; Addition is during greater than 5.0 weight %, reached saturatedly to reaching effect of the present invention, and formed fibrous physical property reduces, the stability variation.Optimal addition need be looked the kind of the organic sulfonate that uses and do suitable adjustment.
