Description
Technical field
The present invention relates to a kind of polyster fibre, relate in particular to a kind of anion wet-guiding terylene fibre and its production and application.
Background technology
Terylene (PET) fiber, function admirable, of many uses low because of its cost is subjected to people day by day and payes attention to.The American produces terylene since nineteen fifty-three, and by 2002, whole world polyster fibre total output was 1882.5 ten thousand tons, and wherein long filament is 1071.9 ten thousand tons.Terylene has become utilization fiber the most widely.People had proposed many method of modifying to the PET fiber and make Woven fabric and clothes have more wearing comfortableness and wholesomeness in recent years.But the PET fiber can not be realized multiple functional coexistence for a long time, has limited the variation of fabric variety.
In recent years, the research of leading the raising of wet and anionic property about PET fiber heteromorphosis has had breakthrough progress respectively, but how these two functions are organically combined, realization fiber heteromorphosis is led unification wet and high effect negative ion, although caused the concern of Chinese scholars, not seeing so far has any report.Technology as following bibliographical information:

Above bibliographical information only limits to the one-side modification of fiber being led wet or anion basically; And how both are organically combined, be that the problem that solves is extremely expected in relevant field.
Usually the solution polyster fibre is led wet approach has following several: a kind of is by introducing hydrophilic radical in the methods such as copolymerization (comprising grafting and block copolymerization), blend, face coat; Another kind is to change fibre section shape (trilobal cross, cross, king's word, hollow etc.) to reduce the special number of monofilament and make fibrous inside have micropore shape structure, its objective is and change the smooth complete surface texture of terylene, utilize micropore capillary water absorption principle, increase specific area.In the practical application, except that these two class methods of independent use, also have these two kinds of methods to be combined and the trend of usefulness.The difference of various weaves also has very big influence for the fabric wetness guiding ability aspect weaving process simultaneously.Developing thin dawn chemical fibre dimension on this basis also can obviously improve fiber and lead wet ability.How, on the basis of control process complexity and cost, improve to greatest extent and lead wet ability these technology reasonable combination, no matter hot and cold, can both give comfortable sensation, mentioned agenda.
Current terylene negative-ion fiber method of modifying can reduce following two aspects.One, fiber, fabric coating method: a kind of ore utilization nanometer technology that can produce anion is made superfine powder (anion powder), this powder is assigned in certain solution makes finishing agent, adopt the method for back arrangement to handle fiber or fabric again.This method is simple, anion emission rate height, but exist shortcomings such as big to equipment attrition, that washability is relatively poor.
Two, melt-blending process: anion powder and high polymer section blend extruded make functional master batch, the melt spinning of again master batch and high polymer being cut into slices makes fiber.The fiber anion emission function that this method makes is lasting, washability is superior, but the difficult control of its production process, its distinct issues are the dispersion problem of superfine powder in polymeric matrix, this also is a common difficult problem studying nano composite material at present and run into.
Along with the development of nanometer technology, negative-ion fiber development and some difficult problems that industrialization faced will progressively be solved, and people will seek more kinds of natural mineral matters with more superior anion emission function simultaneously.In addition, also there is the researcher that some other functional powder (as: ceramic powder, antibiotic powder etc.) is mixed with anion powder again and makes fiber: on the one hand in the hope of strengthening anion emission function with polyblend; Make fiber can have multiple function simultaneously on the other hand, increase the added value of fiber.
