Abstract
The invention discloses a kind of preparation of the silver-colored silicon complex antimicrobials with permanent antibacterial action and process feather technique. No matter be the preparation of silver-colored silicon compound or the processing to feather (suede), technique is all very simple, does not substantially need increase equipment, and compared with current treatment process, cost increases seldom, but the quality of product improves greatly. As lasting in antibacterial effect, surperficial nondiscolouring, good permeability, comfortable and easy to wear.
Description
Technical field
This patent relates to a kind of preparation technology of the silver-colored silicon complex antimicrobials with permanent antibacterial action.
Background technology
The features such as light, soft, warm and " can breathe " having due to feather down, nowadays advocate " green consumption ", " return fromThe today of consumption concept such as so ", be more and more subject to various countries consumer's favor, day by day become the main flow of clothes, bedding, there is other product institutesIrreplaceable advantage. But simultaneously easily absorbing sweat easily causes microbial reproduction growth, not only produces peculiar smell, be also unfavorable for that user's is healthy.Therefore, how to obtain antibacterial finishing agent safe, comfortable, that feather down is had again to a durable antibiotic effect and just seem extremely important.
Early stage antiseptic substantially all belongs to organic series, is all kinds of complex compounds of the elements such as nitrogenous, sulphur, chlorine mostly, its main productPlant and have: quaternary ammonium salt, biguanides, alcohols, phenols, aldehydes, organic metal class, pyridines, thiophene-based etc. Such antiseptic short-term sterilizationEffective, but mostly have, heat-resistant stability is poor, the life-span is short, toxicity is relatively large, and excitant is also strong, sets it as antiseptic and is applied in featherOn suede, be dissolution type, easily wash-out, and easily in human body surface enrichment gradually, long-term use easily produces pathology. Cannot meet the safe, easypro of peopleAccommodate the antibacterial requirement of persistence. Have bibliographical information Nano Silver to process fabric and make it have antibacterial action, but Nano Silver is easily oxidized, and makes featherSuede flavescence look, affects attractive in appearance, not water-fastness equally in addition. In order to improve the washability of antibacterial finishing agent, Chinese scholars is passed through existing arrangementAgent chemical modification introduces active group, synthesized self there is the novel finishing agent of reactivity and potential reaction that preparation can activating and regenerating antibacterialFinishing agents etc., as the organosilicon quaternary ammonium salt antibacterial finishing agent of current document wide coverage (as the DC-5700 of Dow corning company), collect antibacterial effectGood, the safety non-toxic of fruit and wash resistant, have solved a difficult problem for antibacterial finishing agent existence. But organosilicon quaternary ammonium salt complex manufacturing, consumptionGreatly, price is high, this has seriously restricted it and has promoted the use of. Therefore simple, with low cost, the safety non-toxic of development technology and there is permanent antibacterial actionAntibacterial finishing agent still have important realistic meaning.
Summary of the invention
The present invention is directed to not wash resistant that existing antiseptic exists or complex process, expensive shortcoming, provide one to have foreverThe preparation technology of the silver-colored silicon complex antimicrobials of antibacterial action for a long time. The feather that this technological process is simple, with low cost, product safety is nontoxic, treatedSuede not only has permanent antibacterial action, and antistatic, flexibility good, high resilience, whiteness does not obviously change.
Detailed description of the invention
Below in conjunction with specific embodiment, further set forth the present invention. These embodiment are only not used in and limit this for the present invention is describedBright scope. In addition should be understood that after having read the content that the present invention lectures, those skilled in the art can to the present invention do various changes orAmendment, these equivalent form of values are equally in the application's appended claims limited range.
Embodiment 1
The step of preparation process of silver silicon complex antimicrobials is as follows:
1) preparation of silver-colored silicon composite antibacterial finishing agent: by water-soluble amino silicone oil, molecular formula isNH2CH2CH2NHCH2CH2CH2SiCH3(OCH3)2, its active constituent content is 30%, by silicone oil: water-soluble nano silver sol (concentration200 μ g/mL, particle diameter 5-10nm): distilled water (volume ratio) is 1: 1: 38, is uniformly mixed and obtains silver-colored silicon complex antimicrobials under room temperature.Like this, in complex antimicrobials, the concentration of Nano Silver is 5 μ g/mL, and the concentration of amido silicon oil is initial concentration 2.5%, and active constituent content is0.75％。
2) this product adds in the time of the rear arrangement of feather (suede), in the last rinsing of hair, enters after dewaterer dehydration, adds above-mentioned preparationGood silver-colored silicon composite antibacterial finishing agent, addition 20mL/g is in feather. Mix rear immersion about 10 minutes, can dewater, then send into bakingCase is dried (in 100～120 DEG C of temperature, stopping about 10 minutes), then cooling packing.
Compared with current antibacterial finishing agent, advantage applies of the present invention is in the following aspects:
1) persistent high efficiency sterilization, antibacterial: this product can with the protein fibre generation chemical bonds such as feather (suede), feather (suede) after treatmentCan durablely resist and press down various microorganisms, there are selfings at about 110 DEG C in the hydroxyl that amino when oven dry in amido silicon oil molecule and methoxyl group hydrolysis produceConnection effect, forms fine and close network structure on object being treated surface, effectively ensured the slow release of silver ion, thereby realizes durable antibiotic, press downThe object of bacterium. Experiment showed, after washing 20 times, still have high-efficiency antimicrobial, a bacteriostasis, antibacterial, bacteriostasis rate can reach 99.99%.
2) deodorizing: this product can not only be killed the pathogenic microorganisms that may contain in feather (suede), can prevent again in storage, transport, addWhen work and use, be again subject to the erosion of microorganism, the peculiar smell that mould corruption causes occurs.
3) fluffy: amido silicon oil energy rapid osmotic, to feather (suede) inside, makes it reach tough bullet, soft and smooth, fluffy, can improve after testingEider down fluffy degree is more than 10%.
4) antistatic: this product can be combined by the anion in feather (suede), the static of reduction feather (suede).
5) this product also can be used for the antibiotic finish of synthetic fibers, compares and synthetic fibers is added in melt spinning forming process containing having or notThe antibacterial matrices of machine nano silver antimicrobials makes antibacterial and deodouring functional fibre after co-blended spinning, and technique is simple, does not substantially need increase equipment,Cost is low, and antibacterial effect is lasting, surperficial nondiscolouring, and good permeability, comfortable and easy to wear.
