Abstract
The invention provides a production method of inorganic nanometer zinc oxide multifunctional composite antibacterial polyester fiber, comprising the following steps of: firstly preparing hydrophilic modified polyester chip, mixing zinc oxide powder with particle size being less than 100 nanometers with fiber-forming polymer according to the weight ratio of 20-35:80-65, and producing master batch suitable for the production of polyester fiber by a special technology; and mixing the specially-made master batch with the hydrophilic modified polyester chip in the proportion of 5wt%-15wt%, and producing the inorganic nanometer zinc oxide multifunctional composite antibacterial polyester fiber by a production technology of the polyester fiber. The capillary action is increased by the irregular shaping of the cross section of the fiber, so that the fabric generates the wicking due to capillary channels on the fibers or among the fibers to achieve a dry and comfortable wet guide performance; and the modified polyster fiber fabric has the advantages of good hygroscopicity and wearing comfortableness just like natural fiber, and the defect that the cloth made from the natural fiber is attached to a human body closely to make people feel wet and cold when the human body discharge sweat in large quantity can be thoroughly solved as well.
Description
Technical field
The present invention relates to textile industry, relate in particular to the manufacturing approach of synthetic fiber production field inorganic nano zinc oxide multifunctional composite antibiosis polyester fiber.
Background technology
The terylene hygroscopicity is poor; Dress has feeling of oppression and heat; Also be easy to generate serial bacterium, and the hygroscopicity, the gas permeability that how to improve chemical & blended fabric are the problems of paying close attention to both at home and abroad, particularly how on raw material, working hard at garment industry solves the bacterium existing problems and also becomes eternal topic.For keeping well-pressed, the washable characteristic of dacron, improve the comfortableness that it is taken, the special polyester of moisture absorbing and sweat releasing is studied and is released in the U.S. (Du Pont), Japan, Korea S, Taiwan etc. in succession.Short technical a certain distance that also exists of dry-touch type polyester fiber development time; Though the product of mark dry-touch type fiber is also arranged on market; But owing to lack the codes and standards of properties of product and the defective on the processing technology, the performance of product physical property and moisture absorbing and sweat releasing is often not ideal enough.Increase capillarity through fibre section heteromorphosis for this reason, make fabric because on the fiber or interfibrous capillary channel, produce core sucting action and have the dry-touch wet permeability performance.Core sucting action is bigger, and wet transmitting performance better.Obtain to have moisture absorption, the profiled filament of fast dry characteristic, the raw material that the cross section of fiber must have groove, fiber must carry out modification.In the fibre spinning process, add simultaneously antibacterial matrices (nano inorganic antimicrobial agent), spinning has the antibacterial polyester fibre of groove, makes fiber and fabric have dry and comfortable, hydrophilic and antibiotic multi-functional.
And inorganic nano zinc oxide multifunctional composite antibiosis polyester fiber is exactly to process the nano zine oxide antibacterial matrices earlier, adopts the profile spinneret co-blended spinning with modified poly ester then.
Summary of the invention
The object of the present invention is to provide a kind of manufacturing approach of inorganic nano zinc oxide multifunctional composite antibiosis polyester fiber.
The present invention at first prepares hydrophilically modified polyester slice: in the slurry still, add PTA, EG, catalyst, stabilizing agent; Carry out ester exchange reaction in 170-220 ℃,, BHET and oligomer thereof are imported polycondensation vessel when ester exchange rate reaches 96% when above; Add molecular weight and be concentration that 2000～6000 polyethylene glycol and ethylene glycol is mixed with and be 10%～20% slurry and other auxiliary agents; Through 40min normal pressure ethylene glycol mutually after, temperature reaches 250 ℃, again through 20-30min continuously after the decompression; Get into the high vacuum polycondensation reaction stage, temperature is raised to (270 ± 1) ℃.When power of agitator reaches certain value, stop reaction, with the nitrogen vacuum that disappears; With cold rinse bank cooling, Cast Strip, pelletizing; The viscosity Control of percentage by weight 5%～10% section of polyethylene glycol is between 0.68～0.72 in the section, and fusing point is controlled between 235～245 ℃.
With the Zinc oxide powder below 100 nanometers by weight 20～35: 80～65 with the fibre-forming polymer blend, be processed into the master batch that is applicable to that polyester fiber is produced through special process again.Special master batch is made into inorganic nano zinc oxide multifunctional composite antibiosis polyester fiber with the ratio and the hydrophilically modified polyester slice blend of percentage by weight 5%～15% through the polyester fiber production technology.
Triangle hollow shape, trilobal cross, hollow shape, cross are adopted in inorganic nano zinc oxide multifunctional composite antibiosis polyester fiber of the present invention cross section.Its monofilament fineness was 1.2 dawn～3 dawn.
The present invention has significant good effect: 1) give its hygroscopicity to the hydrophobicity polyster fibre; Be employed in the precursor method of modifying of polymerization stage and hydrophilic component copolymerization; Polyethylene glycol is introduced on innovation ground; And molecular weight, the consumption of polyethylene glycol carried out selecting to confirm, synthesize modification section with excellent hydrophilic effect; Cross section Design is unique triangle hollow shape, trilobal cross, hollow shape, cross, and fiber surface vertically becomes groove (secondly area is bigger by 20% than conventional circular cross-section).Increase capillarity through fibre section heteromorphosis, make fabric because on the fiber or interfibrous capillary channel, produce core sucting action and have the dry-touch wet permeability performance; Fabrics of polyester through modification has possessed the natural fabric good hygroscopicity, and advantage comfortable and easy to wear also thoroughly solves natural fabric because of existing when the human body amount of sweat is big, and clothes can cling to the body, and makes us the shortcoming of feeling clammy.Its fabric lacks 14 times than traditional cloth water absorption rate, and is dryer and comfortableer than other functional cloth---and do 5 times than cotton textiles are fast, do 2 times than nylon is fast, thereby improve the pliability and the flatness of fabric, and then improve the wearability of fabric.
2) nano inorganic material has superpower antibacterial deodourizing ability, and human body is not had injury." antibiotic " is meant that growth, breeding, the survival of bacterium is suppressed in the certain hour, and nano zine oxide is compared with organic antibacterial agent as a kind of novel inorganic antibacterial material, has wide spectrum, lasting, safe, nontoxic characteristics.Compare with common anti-biotic material, that nano anti-biotic material has is ageing-resistant, high temperature resistant, be difficult for decomposition, safety and sanitation, advantage such as efficient.The nano zine oxide antibacterial polyester fibre has photocatalysis antibacterial and the antibiotic dual-use function of metal ion stripping.When receiving sunlight and ultraviolet irradiation; Nano zine oxide can decompose and discharge free electron voluntarily in the system that has moisture and air to exist; Stay the hole of positively charged simultaneously; The hydroxyl free radical OH and the superoxide anion free radical O2-that generate are very active, and chemical activity is very strong, can react with multiple organic matter (comprising the organic matter that bacterium is interior and the toxin of secretion thereof) thus bacterium, remains and toxin are killed; And can the stink in the surrounding environment thoroughly be removed, thereby reach the purpose of elimination; Zinc ion can dissociate out gradually, and when he contacted with bacterium, will combine with activated protein in the bacterial body lost activity it, thereby bacterium is killed.
