Abstract
The invention discloses a process for producing bamboo charcoal polyester composite fibers. The process comprises the steps of adding terephthalic acid, glycol, an initiating agent, nano bamboo charcoal micro-powder and a solvent into a polymerization reactor made of stainless steel material; heating the polymerization reactor for continuous polymerization reaction to obtain a mixed stock solution; and filtering the mixed stock solution at the temperature between 50 and 70 DEG C, extruding the filtrate through spinneret orifices, drawing the filtrate in an air layer, and putting the filtrate into bath water to solidify the filtrate into threads, thus obtaining the bamboo charcoal polyester composite fibers. Therefore, by adopting the process for producing the bamboo charcoal polyester composite fibers, the prepared fibers has high extensibility, small difference of wet strength and dry strength, high strength, good shaping stability and capability of improving the durability of a fabric; the fabric has high sunlight resistance and high fluffiness, and the added bamboo charcoal has the functional characteristics of adsorbability, antibiosis and the like, so that the process is simple for preparation, reduces the production cost, and is suitable for large-scale batch industrialized production.
Description
Technical field
The present invention relates to the weaving face fabric field, particularly relate to a kind of production technology of bamboo charcoal polyester complex fiber.
Background technology
In modern society, people are more and more higher to the quality requirement of material life, and as the clothes of people's life necessity, having the ecology and the health that are beneficial to man has become a kind of prerequisite key element.Bamboo-carbon fibre is to get mao bamboon as raw material, adopt pure oxygen, high temperature and nitrogen to intercept the calcine technology of time-delay, refinement and honeycomb obtain bamboo charcoal micropowder more to make micropore that bamboo charcoal innately has, select nano level bamboo charcoal micropowder to mix with section or spinning solution by special processing technology, the conventional spinning technique of foundation spins has the new functional fiber product again.The fabric of making by bamboo-carbon fibre has effect and the functions such as bacteria mildew-proof, absorbing and deodorizing, emission far infrared, more and more is subject to people's favor.
The intensity of the viscose that adopts in the production of general bamboo-carbon fibre is lower, the percentage elongation of fiber is low, dried wet strength differs larger, the typing poor stability, application on fabric has very large limitation, and the durability of fabric reduces greatly, even add a large amount of dispersants in bamboo carbon dacron fiber or the bamboo carbon chinlon, the dispersing uniformity of bamboo charcoal in polymer matrix is difficult to solve, so the application of bamboo charcoal in fabric also has certain limitation.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of production technology of bamboo charcoal polyester complex fiber, and this technique can improve the fabric durability.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of production technology of bamboo charcoal polyester complex fiber is provided, comprises that step is:
