Description
Technical field
The present invention relates to a kind of making process of polypropylene fiber, particularly in polypropylene fibre, contain the making process of polypropylene fiber with mosquito repelling function of culicifuges such as repefral, benzethazet acetofenate or methothrin equably with mosquito repelling function.
Background technology
For avoiding by bite by mosquitos, the gas mosquito repellent is that present people adopt maximum methods, and early stage mosquito repellent gas is generally carried secretly out by flue gas, and is bigger to the harm of human body.By constantly improving, adopt electrical heating low toxicity or nontoxic organic culicifuge directly to volatilize now mostly and produce culicifuge gas, the harm of human body has been reduced to low-down degree.But the method for gas mosquito repellent usually can only be in indoor use, because can't make mosquito repellent gas reach enough concentration because air velocity is very fast in the open air.In the prior art, existing a kind of very suitable field work or sports person avoid the method for bite by mosquitos, i.e. operating personnel's dress has the clothes of keeping away the mosquito effect.It is usually this that to have the clothes of keeping away the mosquito effect be owing to contain culicifuge on the fabric fibre, introduced a kind of polyester fiber with function of driving mosquitoes as Japanese patent application JP10219565, this polyester fiber is to contain by fiber under glass transition temperature that heat treated obtained more than 10 minutes in the solution of culicifuge.Chinese patent 1102767A has introduced a kind of manufacture method of mosquito-repelling socks, after in reactor, polyvinyl alcohol, polyvinyl acetate, mosquito repellent, dodecyl sodium sulfate being added water and making micro-capsule dispersion liquid, adding adhesive, bleeding agent and water again makes and keeps away mosquito liquid, after socks are soaked into therein, extract the whole moulding of scalding again.Have the fiber of mosquito repelling function or fabric in the prior art and generally be by drying or make protomere that is enclosed with culicifuge to stick on fiber or the fabric after fiber or fabric are flooded in the culicifuge soup and make, its ubiquitous problem is that culicifuge only adheres on fiber surface, and wash durability is relatively poor.
Summary of the invention
Technical problem to be solved by this invention provides a kind of making process of polypropylene fiber with mosquito repelling function, contain culicifuge in the polypropylene fibre that obtains equably rather than only be attached to the surface, wash durability obviously improves, thereby can overcome the existing in prior technology defective effectively.
Below be the technical scheme that the present invention solves the problems of the technologies described above:
A kind of manufacturing has the method for mosquito repelling function polypropylene fibre, and this method comprises following process:
1) adding antioxidant and molecular weight regulator evenly mix with culicifuge in the powdered polypropylene resin, and wherein the content of culicifuge is controlled to be 5～10wt%, and the following column weight amount of the addition of antioxidant and molecular weight regulator is recently determined:
Polypropylene: antioxidant=100: 0.4～0.6
Polypropylene: molecular weight regulator=100: 0.01～0.02
Culicifuge is taken from a kind of compound in repefral, benzethazet acetofenate or the methothrin or the mixture of more than one compounds, adopt screw extruder to carry out the granulation of blend heating and melting and make master batch, the heating-up temperature of screw extruder is 150～210 ℃;
2) adopt screw extruder to carry out the blended melting granulation after above-mentioned master batch that obtains and the plain polypropylene mix particles and make spinning material, the heating-up temperature of screw extruder is 150～210 ℃, and the content of culicifuge is controlled to be 1.0～3.0wt% in the spinning material;
3) spinning material carries out the heating and melting spinning after drying and makes long filament or staple fibre in screw extruder, and spinning temperature is 220～260 ℃, and winding speed is 700～2500m/min.
The content of culicifuge preferably is controlled to be 1.0～2.5wt% in said process 2 spinning materials; And process 1 described antioxidant the most commonly used be four [3-(3, the 5-di-tert-butyl-hydroxy phenyl) propionic acid], what molecular weight regulator was the most commonly used is 2,5-dimethyl-2,5-diperoxy tert-butyl group hexane.
The manufacturing of fiber mainly comprises the manufacturing of master batch, full granulation and spinning.The manufacturing of master batch and full granulation process are that culicifuge is warm equably in polypropylene particles, in order to ensure good spinning properties, added an amount of molecular weight regulator, antioxidant during the manufacturing of master batch, these are identical with the requirement of the common polypropylene fibre of spinning all.
Conventional molten spinning is then adopted in spinning, according to different back processing purposes, fiber can be made into the pre-oriented yarn POY that filament number is 1.0～4.0dtex, or further be processed into drafted fibre DT or the elastic filament DTY that filament number is 0.5～3.0dtex, perhaps make the staple fibre that fiber number is 1.0～4.0dtex, the after-processing technology of staple fibre, drafted fibre DT and elastic filament is basic identical with existing similar polypropylene fibre processing technology.
Compared with prior art, advantage of the present invention is that its culicifuge of the polypropylene fibre with mosquito repelling function of making is to be present in the fiber equably rather than only to be attached to the surface, and wash durability obviously improves.In addition, because the polypropylene fibre structure is comparatively loose, exist irregular micropore in the fiber, the culicifuge composition can discharge by micropore lentamente, keeps away the mosquito effect and can keep the longer time.
Because polypropylene fibre and other natural fabric and synthetic fiber and good blending spinning property, the polypropylene fibre that the present invention makes with mosquito repelling function can with natural fabrics such as cotton, wool, flax, or with artificial fibre blending such as terylene, acrylic fibers, polyamide fibre, viscose glue, can make sock and glove, clothes, tent, door curtain, curtain or mosquito net with mosquito repelling function or the like.
