Description
Technical field
The invention belongs to chemical fiber field, specifically is a kind of production method of bamboo charcoal polyester fiber.
Background technology
Bamboo charcoal is that raw material forms through high-temperature firing with the mao bamboon.Its maximum feature is that molecular structure is hexagon, and quality is hard, fine and closely woven porous, the specific area of bamboo charcoal is big, has very strong absorption property, and bamboo charcoal contains abundant mineral matter simultaneously, can produce anion, releasing far infrared, also have the effect of conducting electricity and intercepting electromagenetic wave radiation.
Bamboo charcoal polyester fiber is to be the functional polyalkylene ester fiber that functional additive is made with super Fine bamboo charcoal powder, is a kind of release anion that has, emitting far-infrared outside, the health care fiber of antibiotic, adsorption function.
Chinese patent CN1807714 " bamboo-carbon fibre and preparation method thereof ", CN1939983 " a kind of functional bamboo-carbon powder process and use in synthetic fiber ", CN1590051 " a kind of processing method of bamboo charcoal superfine powder and the application in synthetic fiber thereof " have related to the production method of bamboo charcoal polyester fiber, method is: adopt ultra-fine bamboo-carbon powder, mix the back melt pelletization with synthetic fiber material (polyester), make the master batch that contains the high concentration bamboo charcoal powder, then bamboo charcoal master batch and synthetic fiber material (polyester) blend melt spinning production bamboo charcoal polyester fiber.There is following defective in this method: this technology is difficult to guarantee that bamboo-carbon powder is uniformly dispersed fully in fiber, causes the performance of fiber inhomogeneous; This technology melt spinnability is poor, difficulty in spinning; The Granulation Equipments that this arts demand is special, the production process complexity.
Summary of the invention
The technical issues that need to address of the present invention are at the deficiencies in the prior art, provide a kind of bamboo charcoal to be uniformly dispersed in polyester, spinning properties is good, the production method of the simple bamboo charcoal polyester fiber of production technology.
The production method of bamboo charcoal polyester fiber of the present invention, it is characterized in that, earlier grain through being that the ultra-fine bamboo charcoal powder of 0.3～0.8 μ m is dispersed in and makes bamboo charcoal/ethylene glycol (EG) suspension in the ethylene glycol solution, add above-mentioned suspension and directly produce the polyester that contains ultra-fine bamboo charcoal powder in polyester production process, to produce ultra-fine bamboo charcoal powder content be 0.5～3% bamboo charcoal polyester fiber to melt spinning again.
The preparation of above-mentioned bamboo charcoal/glycolic suspension: add ethylene glycol in material-compound tank, under agitation add ultra-fine bamboo charcoal powder and be made into slurries, pass through ball mill grinding then, be dispersed into uniform suspension, bamboo charcoal content is 10～40% in bamboo charcoal/glycolic suspension.
The grain of ultra-fine bamboo charcoal powder is through meticulous, and the manufacturing cost of bamboo-carbon powder increases; Grain is through big, and the polyester filament spinning component switching cycle that then contains bamboo charcoal is fast, is unfavorable for spinning, so the best grain of ultra-fine bamboo charcoal powder of the present invention is through being 0.3～0.8 μ m.When bamboo charcoal content in bamboo charcoal/glycolic suspension is low, need to consume a large amount of EG, the grinding effect of ball mill descends simultaneously; During the bamboo charcoal too high levels, then the stability decreases of bamboo charcoal suspension when esterification finishes the back interpolation, is unfavorable for that bamboo charcoal is uniformly dispersed, so bamboo charcoal content is 10～40% in bamboo charcoal/glycolic suspension of the present invention simultaneously in polyester.
