Abstract
The invention relates to an anti-ultraviolet polyamide 6 fully drawn yarn. The anti-ultraviolet polyamide 6 fully drawn yarn is made by steps of using polyamide 6 and additives as raw materials on high-speed spinning equipment and adopting a process route of a screw extruder, a pre-filter, a static mixer, a metering pump, a spinning component, trickling, side blowing, oiling, a passage, a first fiber guide roll, a second fiber guide roll, a third fiber guide roll and winding. The process method is simple and feasible, an ultraviolet screening agent and an ultraviolet absorbing agent are added into prepared polyamide 6 fibers, and the microcapsulary is further adopted to enable lasting effectiveness of the anti-ultraviolet performance of the fibers. In addition, the process is applicable to preparation of 20D-70D polyamide 6 filaments, and corresponding dull or semi-dull products can be obtained by adding delustrant for preparation.
Description
Technical field
The invention belongs to the spinning material field, be specifically related to a kind of the section and produce the spinning technique of daiamid-6 fiber.
Background technology
Take synthetic fiber at present terylene (polyester), polyamide fibre (polyamide), polypropylene fibre (polypropylene), spandex (polyurethane), acrylic fibers (polyacrylonitrile) etc. are generally arranged.These fibers have different qualities, thereby different purposes is also arranged.
Daiamid-6 fiber is the synthetic fiber kind that drops into suitability for industrialized production in the world the earliest; It is to be raw material by aliphatic dibasic acid and diamine or aliphatic amino acid through the synthetic polyamide 6 of polycondensation reaction, again through the general name of the prepared one type of synthetic fiber of melt spinning.Owing to all contain amido link therein, so be referred to as daiamid-6 fiber.It belongs to a kind of of heterochain class synthetic fiber.Wherein the output with polycaprolactone nylon (Nylon6, polyamide 6, polyamide 66) and poly fibre (Nylon66, polyamide 66, polyamide 66 6) is maximum, uses the widest.Polyamide fibre is not only industrialized the earliest synthetic fiber kind; And it also has multiple good characteristic; It has higher intensity, elasticity, and wear-resisting weather resisteant is good, thereby the consumers in general's that experience welcome; But along with improving constantly of living standards of the people, people to the diversity of clothes, comfortableness, functional requirement also more and more widely.Fiber finer dawnization, functionalization are important directions of fibre in differentiation development, also are the main development trends of daiamid-6 fiber spinning.Compare with conventional polyamide fibre, differential nylon fibre has more excellent performance: gas permeability, compliance, comfortableness, dyeability, functional etc., exploitation variety classes, just like a raging fire the carrying out of research novel, functional daiamid-6 fiber.
The electromagnetic wave that the sun is launched divides by wavelength, can be divided into gamma-rays, X ray, ultraviolet ray, visible light, infrared ray and microwave, and ultraviolet ray wherein is not only favourable but also harmful to the mankind.Ultraviolet ray has sterilization virus killing effect, can promote the absorption of calcium and vitamin, the prevention osteomalacia.But wrinkle appears in excessive ultraviolet ray irradiation easily quickens skin aging, even the pathology equivalent risk that occurs burning.In recent years, because gases such as the carbon tetrachloride of human a large amount of discharging consumption ozone, fluorochlorohydrocarbon, methane make ozone content reduce year by year.There is data to show, the every minimizing 1% of ozone layer, ultraviolet radiation intensity can increase by 2%, and the human possibility of suffering from cutaneum carcinoma improves 3%.For this reason, people begin to pay attention to the research and development of ultraviolet prevention fiber and fabric thereof.Usually through in fabric, adding ultraviolet light screener, the height through these materials reflects to be realized the ultraviolet ray of incident is reflected and reflected in the prior art, thereby reaches the purpose of ultraviolet radiation preventing; But add inorganic ultraviolet light screener, the poor durability of anti-ultraviolet function.
