Abstract
The inventive polyvinyl chloride fibre, is prepared by adding suitable chlorinated polyvinyl chloride resin, heat stabilizer and active agent into polyvinyl chloride resin, spinning the mixture using a spinning machine equipped with a dry or wet heating apparatus mounted just below a nozzle and maintaining at 100 to 250 DEG C and winding same; drawing the wound fibers at 50 to 100 DEG C, heat treating in dry method at 120 to 180 DEG C or drawing in boiling water at 85 to 100 DEG C, drying at 95 to 130 DEG C and heat treating in wet method at 100 to 140 DEG C. The polyvinyl chloride fibre prepared by the inventive method has the advantages of excellent flame retardant, uniform section and good physical property, and may be used as raw threads for curtain fabric, a carpet, a high quality toy or an artificial wig.
Description
The present invention relates to polyvinyl chloride fibre and manufacture method thereof, relate to the manufacture method of the fiber that the percent thermal shrinkage than existing fiber is significantly improved.More particularly, relate to an amount of polyvinyl chloride (chlorinated polyvinylchloride), heat stabilizer and the lubricant that adds chlorination in Corvic, make pill then, it is reeled off raw silk from cocoons to make extend silk, again polyvinyl chloride fibre and the manufacture method thereof that its stretching and heat treatment are made.
Polyvinyl chloride fibre has good anti-flammability, is used for carpet, bedding class, curtain bottom, child with precursor of doll and artificial hair etc.The present invention is from the fusion manufacturing polyvinyl chloride fibre that reels off raw silk from cocoons, and in order to improve the high shortcoming of polyvinyl chloride percent thermal shrinkage, even produce under high temperature treatment conditions such as boiling water or hot blast the also fiber of rare contraction.
Always, the fiber of only making with polyvinyl chloride.When carrying out damp and hot or dry heat treatment under 100 ℃, length takes place shrink, percent thermal shrinkage reaches more than 20%, can produce to curl and the problem of the original shape of infringement silk.In addition, in making the polyvinyl chloride artificial hair, when curling, shrink, have the shortcoming of the original length of can not get with the heat treatment manufacturing.
The inventor adopts polyvinyl chloride, heat stabilizer and the lubricant that adds chlorination in Corvic, after making the pill shape and carrying out wire drawing, stretch again and heat treated melt drawing method, finish and develop the polyvinyl chloride fibre that percent thermal shrinkage obviously reduces, rerum natura is good.
The objective of the invention is to, provide a kind of anti-flammability good polyvinyl chloride fibre.
Another object of the present invention is to, provide the uniform rerum natura of a kind of section good polyvinyl chloride fibre.
A further object of the present invention is, the polyvinyl chloride fibre with low-shrinkage that a kind of percent thermal shrinkage is low, morphological stability is good is provided.
Another purpose of the present invention is, a kind of manufacture method of using the polyvinyl chloride fibre of melt-out spinning method is provided.
Above-mentioned and other purpose of the present invention can all reach according to the present invention described below.Below describe content of the present invention in detail.
The present invention relates to polyvinyl chloride fibre and manufacture method thereof as fire-retardant silk.Polyvinyl chloride fibre of the present invention, be by an amount of Corvic, heat stabilizer and the lubricant that adds chlorination in Corvic, temperature maintenance after will spray silk stretches and heat-treating methods is made after reeling more than the uniform temperature again.
The Corvic that adds chlorination in Corvic is in order to reduce percent thermal shrinkage.The addition of the polyvinyl chloride of chlorination is that 15～70% of Corvic weight is more preferred from and adds 20～50%.If addition less than 15%, then the effect that reduces of percent thermal shrinkage is small, if more than 70% then fusing point is too high, in particle manufacturing process thermal decomposition takes place, and the xanthochromia phenomenon easily takes place.
Therefore Corvic decomposition temperature and melt temperature must add heat stabilizer for carrying out melt-out spinning much at one.In the present invention, preferably use organo-tin compound, organotin based compound or their mixture of sulfur-bearing as heat stabilizer.
Except the organo-tin compound and organotin based compound of sulfur-bearing, also append the general heat stabilizer of using when using the polyvinyl chloride ejection.As such heat stabilizer, have barium/cadmium system, barium/zinc system, calcium/zinc system, plumbous system, nonmetal be heat stabilizer etc.In addition, for improving stability, also can add stabilizing agent.
The consumption of above-mentioned heat stabilizer is 2～6 parts of weight with respect to 100 parts of weight of Corvic.Under the situation of the organo-tin compound of sulfur-bearing, use 1～5 part of weight.In the occasion of organotin based compound, use 2～6 parts of weight.When the use amount of heat stabilizer was less than 2 parts of weight, when silk spray be not only because of thermal decomposition generation fracture of wire, and coiling in time becomes impossiblely, and when surpassing 6 parts of weight, spray silk and the manufacturability that stretches are bad, the shortcoming that has percent thermal shrinkage to increase.
Because do not add plasticiser in polyvinyl chloride fibre, so mobile bad, fiber forms the performance deficiency, therefore should add lubricant.Lubricant should add internal lubricant and exterior lubricant simultaneously, as internal lubricant, use higher fatty acids, the alcohol of carbon number 14～18 or the montanic acid of carbon number 26～32 of carbon number 14～18,, use paraffin, polyethylene or montanic acid etc. as exterior lubricant.
The use amount of above-mentioned lubricant is 1～4 part of weight with respect to 100 parts of weight of Corvic.When the use amount of lubricant surpassed 4 parts of weight, fused mass was skidded off by nozzle, and the unevenness of the silk of coiling is increased.When being less than 1 part of weight, fiber forms performance and reduces, and reeling, it is impossible to become.
Polyvinyl chloride fibre of the present invention is Corvic, heat stabilizer and the lubricant that adds chlorination with the amount of above-mentioned record in Corvic, and heat treatment manufacturing stretches after this mixture spray silk being reeled again.For the polyvinyl chloride fibre of the present invention of reeling, should establish heater in the positive bottom of nozzle, with temperature maintenance at 100～250 ℃.As heater cylinder heater preferably,, also can use the water vapour of heating or use hot water in order to reel more sleekly.As the spray silk nozzle that can use in the present invention, not only can be circular, and can be any forms such as Y shape, triangle, hollow shape, star, change the sense of touch, gloss, coiling, cardability of wig etc. by such fracture morphology.
By above-mentioned spinning appts spray silk, reel and the polyvinyl chloride fibre intensity of extending is not low, be to improve ductility, must stretch.Polyvinyl chloride fibre of the present invention can stretch with wet method or dry method.Wet method is to stretch in boiling water, for the water after the drying stretching passes through drying machine, passes through heat-treating machine again.Dry method is to utilize dry heating method, and heat-treat immediately without dry run the back that stretches.Not only above-mentioned wet type and dry method, but also can use water vapour to stretch.
When using wet method, 85～100 ℃ draft temperature, 95～130 ℃ baking temperature, 100～140 heat treatment temperature are suitable.When using dry method, 50～100 ℃ draft temperature, 120～180 ℃ heat treatment temperature are suitable.Draft temperature is crossed when hanging down, and is not easy to stretch, and fracture of wire takes place part, and the too high manufacturability that also can make is bad.Heat treatment temperature has direct relation to the percent thermal shrinkage that extends silk, and heat treatment temperature crosses that shrinkage factor uprises when low, when heat treatment temperature is too high, thermal decomposition takes place, and fracture of wire is increased.
The present invention further specializes by following embodiment, and the following example is to be exemplified as purpose with the present invention, and not as the restriction that limits protection domain of the present invention.
