Abstract
The present invention relates to oil for spinning polyacrylonitrile staple fibers, which is prepared from the following components of the proportion by weight: 10 to 25% of open-chain quaternary ammonium salt surfactant, 10 to 25% of fatty acid polyatomic alcohol ester-type non-ionic surfactant whose general formula is R1COOQ, 0 to 8% of fatty alcohol polyethenoxy ether whose general formula is PO(CH2CH2O)nH, and water as the rest, wherein R represents alkyl, X represents sulfate or phosphate, P represents castor oil, and Q represents polyatomic alcohol. With the oil of the present invention for polyacrylonitrile staple fibers, the polyacrylonitrile fiber bundles have soft hand feel, smoothness, bright luster and favorable spinnability, and thus, the quality and the production efficiency of the polyacrylonitrile staple fibers can be improved.
Description
The present invention relates to a kind of finish of acrylic staples spinning, spinning usefulness.
Acrylic fiber is a kind of important chemical fibre, is one of synthetic fiber three big kinds.Copolymer by polyacrylonitrile or acrylonitrile and a small amount of other monomers makes.Because its hygroscopicity is little, poorly conductive, coefficient of friction is big, therefore must use finish to eliminate because of fricative static, adjusts coefficient of friction, guarantees carrying out smoothly of acrylic spinning and back processing.
Acrylic staples generally divides cotton type and two kinds of specifications of wool type, short-staple adopts cotton spinning apparatus processing, wool type fiber uses the wool spinning processing technology, the former has relatively high expectations to the spinnability of finish weaving processing, if the oil performance imperfection just can not pass through each manufacturing procedure such as blowing, comb and parallel cotton fibers prior to spinning, spun yarn smoothly, cause many, the easy broken ends of yarn fault, consume height, weaving efficient is low.And wool spinning processing is low relatively to the spinnability requirement of finish.Usually the acrylic staple fibre finish is made up of antistatic additive, lubricant and other surfactants, and the kinds of surface activating agent is together composite, learns from other's strong points to offset one's weaknesses the performance cooperative effect mutually.Present domestic acrylic staples finish is mostly with alkyl phosphate salt, alkyl polyoxyethylene phosphate salt and trihydroxyethyl methyl quaternary ammonium Methylsulfate makes antistatic host and other single agent are composited, as domestic TZ-48, YQM-3001 etc., Tai Lun-A280, the Tai Lun-A330 etc. of Japan also belong to this type of.U.S. Pat 4072617 discloses a kind of polyacrylic fibre oil, and it is made up of alkylphenol polyoxyethylene, fatty alcohol phosphate, mineral oil, fatty alcohol-polyoxyethylene ether, aliphatic alcohol polyethenoxy phosphate.With regard to present homemade polyacrylic fibre oil, because the component that finish adopted lacks characteristic, the cooperative effect shortcoming, most of finishes are used for wool type fiber and still can, but be used for short-staple, especially the wet spinning short-staple then can not satisfy the requirement of each manufacturing procedure of spinning.The finish of making antistatic host with the phosphate anion surfactant has hygroscopicity owing to phosphate, and its use is subjected to the influence of operating environment humiture bigger, and under the high humidity situation, this oil performance is not good, and the fiber that oils is clamminess.The quality of acrylic staple fibre is except the inherent quality of fiber itself, and the good and used finish of its spinnability also is inseparable, and therefore domestic part acrylic fiber production process factory still uses expensive import finish.
The object of the present invention is to provide a kind of cotton type, wool type acrylic staples Wesy of being applicable to, have excellent anti static behaviour, flexibility, suitable flatness, an oil for acrylic staples of coherent.
The object of the present invention is achieved like this:
Acrylic staples finish of the present invention is to be by structural formula:
Open chain quaternary ammonium salt cationic surfactant 10～25%, its general formula is the polyol esters of fatty acids type non-ionic surface active agent 10～25% of RCOOQ, its general formula is PO (CH

The present invention uses the open chain quaternary cationics can make acrylic fiber have excellent antistatic and flexibility.Use polyol esters of fatty acids type non-ionic surface active agent can make acrylic staple fibre have good flatness, can make acrylic staple fibre have good antistatic behaviour and coherent, use fatty alcohol-polyoxyethylene ether can make the acrylic staple fibre coefficient of friction moderate and make the mutual compatibility of several components, cooperative effect is strengthened.
Acrylic staple fibre finish of the present invention, excellent performance oils evenly the film strength height.This finish can be given acrylic staple fibre excellent antistatic, flexibility, suitable flatness, coherent, soft, smooth with the acrylic staple fibre of its production, gloss is bright, moderate, the good spinnability of frictional coefficient of fiber can be passed through each procedure of textile mills smoothly.Finish of the present invention can improve the product quality of acrylic staple fibre greatly.
