Abstract
The present invention relates to a resin mixture for manufacturing anti-static fine denier and super fine denier polypropylene fibre and its application. It is made up by blending two polypropylene fibres which are different in melt index and antistatic agent polyethylene glycol and sodium alkylsulfonate. Said invention can use conventional spinning or high-speed spinning to produce antistatic fine denier yarn and super fine denier yam whose filament size is 0.6-1.5 dtex., and the antistatic property of said fibre and knitted fabric, woven fabric and non-woven fabric made of said fibre after having been washed 50 times also can be retained within electrostatic half-life less than 20 sec..
Description
The present invention relates to be used to make the resin mixture that antistatic thin dawn and super fine denier polypropylene fibre are used, belong to the high polymer blending and modifying.
Polypropylene fibre is hydrophobic fibre, when the neutralization of its process is stood to rub by its textiles of making, is easy to generate accumulation of static electricity, the easy dust suction of the clothes of making and disagreeable electric-shock feeling is arranged, and dress is uncomfortable, thereby the antistatic property of raising polypropylene fiber is very necessary.Solve three approach of the general employing of antistatic problem: (1) surface preparation, promptly fiber or textile fabrics are carried out impregnation process with antistatic additive, this method is easy, and cost is low, but its antistatic property is often decayed with washing; (2) adopt compound spinning, another component is for having electric conductivity, but cost is more expensive, complex process; (3) adopt antisatic additive, but usually because general antistatic additive adds, the rheological characteristic variation that can cause polymer, the fibre machinery degradation, thereby can not spin out thin dawn superfine Denier fibre, and thin dawn and super fine denier polypropylene fibre can be given textiles and leads wet, ventilative, snugness of fit, thus the added value of raising fabric.
The object of the present invention is to provide a kind of be used to produce have antistatic behaviour (electrostatic half-life＜20 second), fiber number is the blending resin of 0.6-1.3 dtex polypropylene fibre.
For achieving the above object, the present invention is by the following technical solutions: a kind of antistatic thin dawn and super fine denier polypropylene fibre blending resin, form by polypropylene and antistatic additive, it is characterized in that described polypropylene is that the polypropylene A of 31-75 and polypropylene B that melt index is 0.5-30 form by melt index, described antistatic additive is polyethylene glycol (molecular weight 2000-30000) and sodium alkyl sulfonate (alkyl carbon atoms is 12-16), and the percentage by weight of its prescription is:
Polypropylene A 50-98
Polypropylene B 2-50
Polyethylene glycol 0.2-5
Sodium alkyl sulfonate 0.1-5
Above-mentioned blend after screw rod is extruded pelletizing routine spin or high-speed spinning (spin fast 2500-3500 rice/minute) condition under make fine denier filament and the superfine denier fiber that the Antielectrostatic monofilament fiber number is the 0.6-1.3 dtex.
Sodium alkyl sulfonate is a kind of ion-type surface modifier among the present invention; it is made up of hydrophobic group and hydrophilic radical; its hydrophobic grouping combines with polypropylene matrix; hydrophilic radical combines with polyethylene glycol; make the polypropylene-base body interface form protective layer; improve the electric charge translational speed, therefore improved the antistatic behaviour and the anlistatig stability of fiber.
The present invention has following advantage:
1. adopt the composite antistatic additive with suitable molecular weight, make fiber and goods antistatic effect thereof lasting, wash 50 times, its antistatic behaviour still remains in electrostatic half-life＜20 second.
2. adopt the polypropene blended of different melt index, adding can improve the antistatic additive of rheological characteristic, makes mixture have enough flowabilities in spinning process, can spin thin dawn and super fine denier polypropylene fiber.
3. the tensile strength of fiber can be carried out routine and high speed spinning greater than 3.5 lis of newton/dtexs, and technology controlling and process is easy, and weaving processing smoothly.
Below the present invention is further elaborated by example:
Example one:
With melt index be 70 polypropylene A65% (weight) and melt index is that 25 polypropylene B35% (weight) molecular weight is 20,000 polyethylene glycol 2.5% (weight), after dodecyl sodium sulfate 1% (weight) blend, at spinning speed is 800 meters/minute, draw ratio is that its filament number of fiber that obtains under 3.1 times of conditions is 0.7 dtex, 3.8 lis of newton/dtexs of intensity, electrostatic half-life 1 second, ductility 25%.
Example two:
With melt index be 75 polypropylene A70% (weight) and melt index is that 4 polypropylene B30% (weight) molecular weight is 15000 polyethylene glycol 2% (weight), after sodium cetanesulfonate 0.5% (weight) blend, at spinning speed is 3300 meters/minute, draw ratio is under 1.5 times of conditions, its filament number of the fiber that obtains is 1.2 dtexs, 3.7 lis of newton/dtexs of intensity, electrostatic half-life 10 seconds, ductility 22%.
Antistatic thin dawn and the super fine denier polypropylene fibre produced by the present invention can be applicable to knitted product, machine woven article and bondedfibre fabric.
Claims (2)
1. antistatic thin dawn and super fine denier polypropylene fibre blending resin, form by polypropylene and antistatic additive, it is characterized in that described polypropylene is that the polypropylene A of 31-75 and polypropylene B that melt index is 0.5-30 form by melt index, described antistatic additive is polyethylene glycol (molecular weight 2000-30000) and sodium alkyl sulfonate (alkyl carbon atoms is 12-16), and the percentage by weight of its prescription is:
Polypropylene A 50-98
Polypropylene B 2-50
Polyethylene glycol 0.2-5
Sodium alkyl sulfonate 0.1-5
2. be the fine denier filament and the superfine denier fiber of 0.6-1.3 dtex with described antistatic thin dawn of claim 1 and super fine denier polypropylene fibre with the Antielectrostatic monofilament fiber number that blending resin prepares.
