Abstract
The invention provides a method for preparing a composite antibacterial polyester fiber containing nano zinc oxide and titanium dioxide, which is characterized by comprising the following steps: blending a composite antibacterial polyester master batch containing the nano zinc oxide and the titanium dioxide and polyester chips by the weight percent, carrying out vacuum drying by gradually raising the temperature; the production process of the polyester fiber is applied; the spinning temperature is 260 DEG C to 280 DEG C; and the drafting multiple is 3.3 to 3.8. Compared with an organic antibacterial agent, the composite material of the nano zinc oxide and the titanium dioxide as a novel organic antibacterial material has the characteristics of broad spectrum, durability, safety and no toxicity. Compared with an ordinary antibacterial material, the nano antibacterial material has the advantages of aging resistance, high temperature resistance, difficulty of decomposition, safety and sanitation, and high efficiency. The composite antibacterial polyester fiber containing the nano zinc oxide and the titanium dioxide has double functions of photocatalysis antibacterial property and metal ion dissolving antibacterial property.
Description
Technical field
The present invention relates to textile industry, relate in particular to the manufacture method of a kind of nano zine oxide of synthetic fiber production field, titanium dioxide composite antibiosis polyester fiber.
Background technology
Characteristics such as nano material is little because of its particle size, specific area is big, surface energy is high, the surface atom proportion is big have peculiar property and new rule, make it become the research focus of many research fields as quantum size, skin effect and characteristics such as local field-effect, coupling effect.Along with people's living standard day by day improves, more and more higher to the requirement of health, the inexpensive material that strong antibiotic property arranged again obtains further extensively and dark people's research.Nano zine oxide, titanium dioxide are a kind of photochemical catalysts, and solar radiation, fluorescence irradiation, dosage increase all help improving its anti-microbial property.Its Heat stability is good has no side effect to human body and animal body, in medical product and other have the product of antibiotic requirement good production and application prospect is arranged.And nano zine oxide, titanium dioxide composite antibiosis polyester fiber are exactly to make nano zine oxide, titanium dioxide composite antibiosis master batch earlier, then with the polyester blend spinning.
Summary of the invention
The object of the present invention is to provide the manufacture method of a kind of nano zine oxide, titanium dioxide composite antibiosis polyester fiber.
The present invention at first is mixed and made into powder mixture with the zinc oxide below 100 nanometers, titanium dioxide powder, and the weight ratio of mixing is zinc oxide: titanium dioxide=80-90: 20-10; Powder mixture by weight 20-35: 80-65 and fibre-forming polymer blend, is processed into the master batch that is applicable to that polyester fiber is produced through special process again.Special master batch and polyester slice blend are made into nano zine oxide, titanium dioxide composite antibiosis polyester fiber through the polyester fiber production technology.
Nano zine oxide, the titanium dioxide composite antibiosis polyester fiber technological process of production are: with nano zine oxide, titanium dioxide composite antibiosis polyester master particle with percentage by weight 6%-15% and polyester slice blend, after vacuumize, fusion, spinning machine spinning, obtain as-spun fibre to the up-coiler bucket of reeling, fall by the path.Spin before this in process, spinning temperature is 260 ℃～280 ℃, with 265 ℃～275 ℃ be good, spinning speed is 1100～1300 meters/minute.Again through drawing-off, curl, cut off and make nano zine oxide, titanium dioxide composite antibiosis polyester fiber.Drafting multiple of the present invention is 3.3～3.8 times.
Nano zine oxide of the present invention, titanium dioxide composite antibiosis polyester fiber cross section can be any cross sections of known melt spinning, as circle, triangle, trilobal cross, hollow shape, pancake,, L shaped, T shape, W shape, polygon, dog bone shape or the like.Its monofilament fineness was 1.5 dawn～6 dawn.
The present invention has significant good effect:
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, titanium dioxide is compound compares 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.Nano zine oxide, titanium dioxide composite antibiosis polyester fiber have photocatalysis antibacterial and the antibiotic dual-use function of metal ion stripping.When being subjected to sunlight and ultraviolet irradiation, nano zine oxide, titanium dioxide composite antibacterial agent 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 of generation and superoxide anion free radical O
2 -All very active, chemical activity is very strong, can react with multiple organic matter (comprising the organic matter in the bacterium and the toxin of secretion thereof) thus bacterium, remains and toxin are killed, and the stink in the surrounding environment thoroughly can be removed, thereby be reached the purpose of elimination; Zinc ion can dissociate out gradually, and when he and bacterium contacted, will combine with activated protein in the bacterial body lost activity it, thereby bacterium is killed.
