Description
Technical field
The present invention relates to fiber production field, more particularly to a kind of production method of antistatic fiber.
Background technology
Silver is the metal that resistivity is minimum in all metals, so having high conductivity, is resistant to 5000 volts of electrostatic, has
Electro-magnetic screen function, as long as a small amount of silver fiber is present on clothing, it will rapidly eliminate because of electrostatic caused by friction, and have product
The comfort of electrostatic is whether there is, therefore silver fiber quickly and efficiently can conduct electrostatic to rate very much, human body can be protected to exempt from
Foetus is especially protected to pregnant woman from electromagnetic wave influence by electromagnetic wave infringement and is ensured attached in electromagnet sources such as computers for a long time
The health of nearly staff has important health-care effect.The mechanism of argent sterilization is exactly to block the physiology course of bacterium.
Under wetting conditions, silver ion can make the protein coagulating inside and outside bacterial cell membrane, so as to block the breathing of bacterial cell and breeding
Process.The antibacterial ability of silver ion is very surprising, and the silver of parts per billion milligram is with regard to that can purify 1 kilogram of water.Common antibiotic
Six kinds of different pathogen can be eliminated, and the antibiotic of argentiferous can then eliminate more than 650 kinds of pathogen.This spy of silver-colored material
Property, before more than 2,000 years, in terms of being just widely used in medicine.Just because of the excellent antibacterial function of silver, silver fiber have
Mould proof odour repellent function.
Chinese patent application 200410024079.8 discloses a kind of preparation method of silver-plated fiber fabric, and it is knitted with chemical fibre
Thing or terylene non-woven fabric make matrix, under the protection of nitrogen or argon gas, using ion plating method is silver-plated or stainless steel, then pass through biography
The electroplating plastic technique of system is in the continuous nickel plating of matrix surface, copper or silver, last one layer of silver of re-plating, produce it is non-take have
The silver-plated fiber fabric of shielding properties.
And golden yellow color fibre of the prior art is typically using the wire drawing of true yellow gold or yellow by being added in chemical fibre
Golden pigment obtains.The defects of obvious be present in this two eka-golds yellow fibers, on the one hand, and the former is expensive, such as 2011 years
Nylstar companies of the U.S. develop a kind of 24KNylgold gold fiber, it is said that have skin care, beauty, anti-aging effects, but every gram
Price is more than 90 U.S. dollars；The latter does not shield, antibacterial effect, and due to introducing chrome yellow containing toxic element Cr, medium chrome yellow
Chemical pigment, fiber can not be compared with " coating ", it is difficult to exist with avoiding a certain degree of with the fastness of the combination between pigment
Pollution, it is not appropriate for home textile product use.On the other hand, the golden yellow color fibre prepared using true yellow gold drawing process is not also had
There is the absorbing sweat of natural cotton fiber, breathe freely, comfortable wears performance, be difficult to take；By adding gold in chemical fibre
Color pigment obtain golden yellow color fibre, due to using chemical fibre as base material, the discarded object after its use in nature very
Difficult degradation, it is unfavorable for environmental protection.
