Abstract
The invention provides negative ion polyvinyl chloride fiber for wig and a preparation method thereof. The negative ion fiber uses polyvinyl chloride resin as a base body, negative ion powder with the grain diameter between 0.1 and 3mu m, CPVC (chlorinated polyvinyl chloride) and PVC (polyvinyl) resin, stabilizing agents, auxiliary stabilizing agents, inner lubricating agents, outer lubricating agents, impact resistance modifying agents and pigment are added into the base body, the mixture is uniformly mixed in a mixing groove according to a certain proportion, and is fused into fused mass through a screw extruder, the fused mass is compressed and homogenized, then enters a spinning box body through a bended pipe to be distributed to each spinning position, and is finally sprayed out through a metering pump and a spinning assembly, fine flows of the sprayed fused mass are slowly cooled after being heated by a heating sleeve, and are then wound on a sleeve pipe after being oiled and moistened, the fiber is then stretched, retracted, cooled and formed to be made into finished fiber products, and the finished fiber products are used for preparing the wig after being packed.
Description
Technical field:
The present invention relates to a kind of technology of preparing of functional form fiber, particularly a kind of technology of preparing that is used for the anion polyvinyl chloride fibre of wig.
Background technology:
Current, the hair products of being described as " fashionable dress on the head " by people have become " the new product gang " of fashional consumption, but present wig generally all only has decoration function, the wig product of functional form is also few in number, and the prepared negative-ion fiber of the present invention can be made anion far-infrared functional health wig.
Anion is meant atom, the atomic group (comprising molecule) that has negative electrical charge.Said anion is meant the oxonium ion that has negative electrical charge, hydration hydroxyl ion etc. among the present invention.A large amount of anions is contained in general waterfall, forest, high mountain, wilderness, and these places generally can make the people feel relaxed and joyful, and are happy.This is because anion has been brought into play its effect.For human body, anion has the cell metabolism of promotion, increases body's immunity, improves pulmonary function; Adjust blood pH, decompose cholesterol, make blood flow happy; Stable nerve, improvement are slept, are lessened fatigue; Anti-inflammatory analgetic impels multiple disease spontaneous recovery.For environment, anion has very high activity, very strong redox is arranged, can destroy the activity of bacterium or other material, therefore can purify air, adsorb micronic dust, eliminate peculiar smell (noxious odor that cigarette stink, chemicals or art work come out) etc.So sanatorium is arranged near high mountain, flowing water or the forest more.
The selected anion powder of the present invention has pyroelectricity and piezoelectricity, therefore under the situation that has temperature and pressure to change (even small variation), cause the electrical potential difference between the anion crystal, this static is up to 1,000,000 electron-volts, thereby make gas molecule generation ionization in the air, in near water and oxygen molecule, and made it be converted into negative aeroion by the electron attachment hit.
Anion powder also has far-infrared transmitting function, anion powder is because of its pyroelectricity and piezoelectricity, make its polarity ion cause that in the equilbrium position vibration dipole moment changes the electromagnetic radiation that produces far infrared band, and the anion powder polar molecule of blending by a certain percentage can fully be mixed in the texture of organic matter fiber, form uniform island structure with the nonpolar molecule group of fiber, have stronger radiation broadband, according to test negative ion health fiber to far emissivity more than 82%.Far infrared has excellent health care to human body.
The foreign study personnel find, when polyvinyl chloride fibre and human body rub mutually, can make negative electricity on the moisture subband floating in the surrounding air, quantity in every cubic centimetre can reach 880 to 2020, the reason that produces this phenomenon may be that the chlorosity in the polyvinyl chloride easily loses electronics, and very little energy just can make airborne particulate charged.But this anion quantity is equivalent to the level of town park to the greatest extent, is the level of keeping health, does not have treatment and function of health care.The present invention has overcome the complexity of polyvinyl chloride high pressure melt-spun, successfully the nano-negative ion powder is added in the polyvinyl chloride fibre, has prepared the anion far infrared health care type wig that can really be referred to as " Forest Bath ".
Use this health anion wig, to having cardiovascular and cerebrovascular disease, respiratory disease, the bad people of pulmonary function to have the fabulous function of improving, can eliminate human-body fatigue in addition, improve breathing environment, the people easily irritated to face also has fabulous prevention effect.
The anion polyvinyl chloride fibre of this method preparation is brought into play its effect except that being used for wig, and suitable adjusting process is prepared the negative ion health fiber of different fiber numbers.Can be made into fabric with this negative-ion fiber, be used for clothes, bedding, towel etc.; Also can make indoor ornament, as the wallpaper, carpet, slip cover, mat etc. of decoration usefulness; Can make short fiber, the preparation down toy; Can be used as medical woven cloths, as operating coat, nursing clothes, sick bed articles for use etc.; Filtering material be can prepare, air filtration, water filtration and water treatment aspect are used in.Thereby more fully bring into play its excellent anion far infrared health care function.
