Description
Technical field
The present invention relates to the product in a kind of textile fiber technology field and preparation method thereof, particularly relate to a kind of viscose material and preparation method thereof.
Background technology
Along with the raising of people's living standard, the requirement of people to underclothes material is also more and more higher.Fiber textile, at dress or the effluent such as sweat, sebum that can absorb human secretory in using, very easily becomes carrier and the communication media of germ parasitized breeding, directly or indirectly affects the healthy of people.Thus can grow and reduce the antibacterial fabric of skin infectious disease by anti-bacteria, becoming one of functional textile most popular with consumers.At present, antibacterial fabric mainly adds organic antibacterial agent by postfinishing process or adds in the fibre spinning stage that the inorganic material such as such as silver, copper, zinc oxide realizes.But the former water-wash resistance is not good, and easily damage is caused to skin, and the latter not only cost is high, and due to the heavy metal introduced easily free out, cause variable color and also have worth Some Opinions to the impact of environment and human body.
In addition, though antibacterial fabric can prevent by bacteriogenic peculiar smell.But to the peculiar smell that other approach produces, the cigarette in as smelly in the bad smell of perspiration of human body, underarm odor, old man and environment is smelly, formaldehyde etc. is felt simply helpless.So can decompose or adsorb various peculiar smell, the smelly eliminating fabric building fresh and comfortable environment to people receives increasing concern.At present, mainly to add deodorant by postfinishing process or add in the fibre spinning stage that such as bamboo charcoal isoreactivity charcoal composition or catalysis material realize.But the former declines obviously at effect after washing; And the fibers such as bamboo charcoal are black gray expandables, painted difficulty, limits its range of application; Photocatalytic fiber then needs the effect of Ultraviolet radiation competence exertion, and the scope of application is narrow.
In the autumn and winter season of drying, human skin very easily causes pruitus because of lack of water, redness even comes off, usual people can adopt and smear all kinds of moisturiser to prevent or treat, but whole body smear waste time and energy and the duration not as people's will, therefore can uninterruptedly provide the moistureretaining fabric of the suitable moisture of skin to become the focus of consumption for 24 hours.At present, mainly or in the fibre spinning stage add that the organic moisture such as such as aloe, collagen, glycerine becomes to assign to realize, but water-wash resistance is not good.
Meanwhile, along with development and the growth in the living standard of national economy, people start to favor frivolous warm clothing and replace in the past thick and heavy winter coat, and various fabric that is warming, heating arises at the historic moment, and becomes the focus in market.At present, the market mainstream has far infrared, heat storing and heat preserving, moisture absorption heating, hollow warm-keeping fiber etc.
Viscose is the cellulose fibre produced for raw material with cotton or other natural fabric.In 12 kinds of main textile fabrics, the moisture percentage of viscose meets the physiological requirement of human body skin most, have smooth nice and cool, ventilative, antistatic, dye the characteristic such as gorgeous.As one of three large raw materials (cotton, terylene, viscose glue) spinned, viscose has the advantage of cotton and terylene concurrently: the functions such as its moisture absorption, anti-electricity and softness are better than terylene, and its drapability and dyeability are better than cotton fiber.
Through finding the retrieval of prior art, patent document publication number CN1544725A describes one " antibacterial viscose fiber and production technology thereof ", this technology is mainly through by antiseptic, mainly aromatic halogen compound, organosilicone quaternary ammonium salt compounds, and/or comprise to mix with viscose glue after organic oxidized compound makes antibacterial mother liquor after spinning prepare antibacterial viscose glue.But the viscose of the prior art does not comprise smelly eliminating and moisturizing heating function.
Patent document publication number CN1779004A describes one " antibacterial viscose fiber and production method thereof ", and this technology is realized by silver antibacterial agent and cellulose sulfonate co-blended spinning.But the viscose of the prior art does not comprise smelly eliminating and moisturizing heating function.
Patent document publication number CN1936124A describes one " silver-containing antibacterial viscose fiber and preparation method thereof ", and nano-class silver colloidal solution is mixed into viscose glue to realize when spinning by this technology.But the prior art does not comprise smelly eliminating and moisturizing heating function.
Patent document publication number CN103015170A describes one " manufacture method of antibacterial and deodorizing viscose face fabric ", and this technology, mainly through being flooded in copper ammon solution by viscose face fabric, obtains copper chelating viscose fabric and has antibacterial and function that is smelly eliminating.But the prior art can only process fabric, can not process fibre and yarn, water-wash resistance is also undesirable, its range of application is limited to, and does not comprise moisturizing heating function.
Patent document publication number CN101440534A describes one " nano bamboo charcoal anti-bacterial fiber and manufacture method thereof ", this technology is mixed with bamboo charcoal nano by Nano Silver, after obtained nano bamboo charcoal antibacterial liquid slurry, it is mixed with alpha cellulose, according to adhering process production method, nano bamboo charcoal anti-bacterial fiber can be obtained through wet spinning and post processing.This fibre antibacterial rate reaches more than 98%, also has certain smelly eliminating effect, but due to fiber color be grey black, the fabric of white or light color cannot be made, limited to its application, and do not comprised moisturizing heating function.
