Description
Technical field
The present invention relates to textile industry, particularly relate to the manufacture method of synthetic fiber production field inorganic nanometer zinc oxide multifunctional composite antibacterial polyester fiber.
Background technology
Terylene hygroscopicity is poor, dress has feeling of oppression and heat, also easily produce serial bacterium, and how to improve the hygroscopicity of chemical & blended fabric, gas permeability is the problem paid close attention to both at home and abroad, particularly how making an effort on raw material at garment industry solves bacterium existing problems and also becomes eternal topic.For retaining well-pressed, the wash durability of dacron, improve the comfortableness that it is taken, the U.S. (Du Pont), Japan, Korea S, Taiwan etc. are in succession studied and are released the special polyester of moisture absorbing and sweat releasing.The dry-touch type polyester fiber development time is short technically also exists a certain distance, although commercially also there is the product of mark dry-touch type fiber, but because shortage is to the defect in the codes and standards of properties of product and processing technology, the performance of product physical property and moisture absorbing and sweat releasing is often not ideal enough.Increase capillarity by fibre section heteromorphosis for this reason, make fabric due on fiber or interfibrous capillary channel, produce core sucting action and there is dry-touch wet permeability performance.Core sucting action is larger, and wet transmitting performance better.Obtain the profiled filament with moisture absorption, fast dry characteristic, the cross section of fiber must have groove, the raw material of fiber must carry out modification.In fibre spinning process, add antibacterial matrices (nano inorganic antimicrobial agent), the reeded antibacterial polyester fibre of spinning band, makes fiber and fabric have dry and comfortable, hydrophilic and antibacterial multi-functional simultaneously.
And inorganic nanometer zinc oxide multifunctional composite antibacterial polyester fiber is exactly first make nano zine oxide antibacterial matrices, then adopt profile spinneret co-blended spinning with modified poly ester.
Summary of the invention
The object of the present invention is to provide a kind of manufacture method of inorganic nanometer zinc oxide multifunctional composite antibacterial polyester fiber.
First the present invention prepares hydrophilically modified polyester slice: in slurry kettle, add PTA, EG, catalyst, stabilizing agent, ester exchange reaction is carried out in 170-220 DEG C, when ester exchange rate reaches more than 96%, BHET and oligomer thereof are imported polycondensation vessel, add molecular weight be 2000 ~ 6000 polyethylene glycol and the concentration that is mixed with of ethylene glycol be 10% ~ 20% slurry and other auxiliary agents, through 40min normal pressure ethylene glycol mutually after, temperature reaches 250 DEG C, again after 20-30min reduces pressure continuously, enter the high vacuum polycondensation reaction stage, temperature is raised to (270 ± 1) DEG C.When power of agitator reaches certain value, stop reaction, to disappear vacuum with nitrogen, with cold rinse bank cooling, Cast Strip, pelletizing, the viscosity that in section, the percentage by weight 5% ~ 10% of polyethylene glycol is cut into slices controls between 0.68 ~ 0.72, and fusing point controls between 235 ~ 245 DEG C.
Zinc oxide powder below 100 nanometers is blended with fibre-forming polymer by weight 20 ~ 35: 80 ~ 65, then the master batch being applicable to polyester fiber and producing is processed into through special process.Special master batch with the ratio of percentage by weight 5% ~ 15% and hydrophilically modified polyester slice blended, be made into inorganic nanometer zinc oxide multifunctional composite antibacterial polyester fiber through polyester fiber production technology.
Inorganic nanometer zinc oxide multifunctional composite antibacterial polyester fiber cross section of the present invention adopts triangle hollow shape, trilobal cross, hollow shape, cross.Its monofilament fineness be 1.2 dawn ~ 3 dawn.
The present invention has significant good effect: 1) give its hygroscopicity to hydrophobicity polyster fibre, adopt the precursor method of modifying at polymerization stage and hydrophilic component copolymerization, innovatively introduce polyethylene glycol, and carried out selecting to determine to the molecular weight of polyethylene glycol, consumption, synthesize the modification section with excellent hydrophilic effect; Cross section Design is unique triangle hollow shape, trilobal cross, hollow shape, cross, and fiber surface longitudinally becomes groove (secondly area ratio conventional circular cross section large 20%).Increase capillarity by fibre section heteromorphosis, make fabric due on fiber or interfibrous capillary channel, produce core sucting action and there is dry-touch wet permeability performance; Possessed natural fabric good hygroscopicity by the fabrics of polyester of modification, advantage comfortable and easy to wear, also thoroughly solve natural fabric because existing when human body amount of sweat is larger, clothes can cling to the body, and makes us feeling clammy shortcoming.Fewer than traditional cloth water absorption rate 14 times of its fabric, dryer and comfortableer than other functional cloth---than textile quick-drying 5 times, than nylon quick-drying 2 times, thus improve pliability and the flatness of fabric, and then improve the wearability of fabric.
2) nano inorganic material has superpower antibacterial deodourizing ability, and to human body fanout free region." antibacterial " refers to that the growth of bacterium in certain hour, breeding, survival are suppressed, and nano zine oxide compared with organic antibacterial agent, has wide spectrum, lasting, safe, nontoxic feature as a kind of novel inorganic antibacterial material.Compared with common anti-biotic material, nano anti-biotic material has ageing-resistant, high temperature resistant, not easily decomposition, safety and sanitation, the advantage such as efficient.Nano zine oxide antibacterial polyester fibre has photocatalysis antibacterial and the antibacterial dual-use function of digestion of metallic ion.During by sunlight and ultraviolet irradiation, nano zine oxide can disintegrate discharge free electron in the system having moisture and air to exist, leave the hole of positively charged simultaneously, the hydroxyl free radical OH generated and superoxide anion radical O2-is very active, chemical activity is very strong, can react with gas chromatography (toxin comprising organic matter in bacterium and secretion thereof) thus bacterium, remains are killed together with toxin, and the stink in surrounding environment thoroughly can be removed, thus reach the object of elimination; Zinc ion can dissociate out gradually, when he contacts with pre biooxidation, will combine and make it lose activity, thus killed by bacterium with activated protein in bacterial body.
