【摘要】：抗菌織物通過制備抗菌纖維后織造成織物和織物抗菌后整理工藝兩種方式得到。前者相較于后者工藝流程復(fù)雜,對抗菌劑的物化性能要求較高,但前者獲得的織物抗菌劑用量少、抗菌效果好、耐洗性高。本文采用兩種方式得到抗菌織物:一是預(yù)先制備抗菌母粒,經(jīng)過熔融紡絲得到抗菌纖維,再將抗菌纖維紡織成抗菌織物;二是將織物經(jīng)涂層后得到抗菌織物。定性測試操作簡單,檢測快速,但不能準(zhǔn)確得出織物抗菌率。定量測試方法中應(yīng)用較為廣泛的有吸收法和振蕩法兩大類,得到的測試結(jié)果能夠客觀的評價織物抗菌性能。本文在AATCC-100法和振蕩法的基礎(chǔ)上,采用改良AATCC-100法和改良振蕩法檢測織物對大腸桿菌和金黃色葡萄球菌的抗菌性能,使測試方法更符合抗菌織物性質(zhì)。目前國內(nèi)外采用的織物抗菌劑主要分為無機(jī)抗菌劑、有機(jī)抗菌劑和天然抗菌劑。無機(jī)抗菌劑以其具備良好的耐熱性、持久性、連續(xù)性和安全性,被廣泛應(yīng)用到抗菌織物中。近年來,銀系抗菌劑、銅系抗菌劑、鋅系抗菌劑等涉及重金屬的使用,故采用環(huán)境友好型抗菌劑是趨勢所在。本文采用鎂基材料作為抗菌劑制備抗菌織物,符合環(huán)境友好型材料的發(fā)展趨勢,得到的織物為環(huán)境友好型抗菌織物�？咕w維或織物在涉海人員健康保護(hù)、船舶污水處理和船舶廢氣處理等諸多方面均有廣泛應(yīng)用。實驗結(jié)果表明:(1)1250目、2500目和5000目的水鎂石原粉復(fù)配比例為1:1:2時,粉體致密,堆積密度大,制備的鎂基涂層織物表面光滑。(2)納米鎂基粉體和PET母粒復(fù)配比例為1:4時制備成鎂基母粒。(3)制備成納米鎂基粉體含量在1%～5%內(nèi)的鎂基織物。(4)鎂基涂層織物對大腸桿菌抗菌作用良好,抑菌率在90%以上,對金黃色葡萄球菌抗菌效果較差。(5)采用鎂基母粒制成的織物抗菌作用良好,納米鎂基粉體添加量5%的織物對大腸桿菌和金黃色葡萄球菌的抑菌率均達(dá)到90%以上。
[Abstract]:Antimicrobial fabrics were obtained by the preparation of antibacterial fibers and the antibacterial finishing process.Compared with the latter, the former process is complex and requires higher physical and chemical properties of antimicrobial agents, but the former has the advantages of small amount of fabric antimicrobial agents, good antibacterial effect and high washing resistance.In this paper, antimicrobial fabrics were obtained by two methods: first, the antibacterial masterbatch was prepared in advance, then the antibacterial fiber was obtained by melt spinning, and then the antibacterial fiber was woven into the antibacterial fabric; the second, the antibacterial fabric was obtained after the fabric was coated.The qualitative test is simple and rapid, but it can not get the antibacterial rate of fabric accurately.There are two kinds of quantitative testing methods: absorption method and oscillatory method. The results can objectively evaluate the antibacterial properties of fabrics.Based on the AATCC-100 method and the oscillatory method, the modified AATCC-100 method and the modified oscillatory method were used to detect the antibacterial properties of the fabric against Escherichia coli and Staphylococcus aureus.At present, fabric antimicrobial agents used at home and abroad are mainly divided into inorganic antimicrobial agents, organic antimicrobial agents and natural antimicrobial agents.Inorganic antimicrobial agents are widely used in antibacterial fabrics due to their good heat resistance, durability, continuity and safety.In recent years, the use of heavy metals is involved in the use of silver, copper and zinc series antimicrobials, so the use of environment-friendly antimicrobial agents is the trend.In this paper, magnesium base material was used as antimicrobial agent to prepare antibacterial fabric, which was in line with the development trend of environment-friendly material, and the obtained fabric was environment-friendly antibacterial fabric.Antibacterial fibers or fabrics are widely used in marine health protection, ship sewage treatment and ship waste gas treatment.The experimental results show that the powder is dense and the bulk density is high when the mixture ratio of 5000 object brucite and 1 250 mesh brucite raw powder is 1:1:2.The magnesia-based coated fabric containing 1% or 5% magnesium matrix powder has good antibacterial effect on Escherichia coli, when the surface of the coated fabric is smooth and the PET masterbatch is composed of nano-Mg-based powder and PET masterbatch at 1:4, and the magnesia-based masterbatch is prepared with the content of nano-Mg-based powder within 1%, and the content of Mg-base powder is less than 1%, and the magnesium-based coated fabric has good antibacterial effect on Escherichia coli.The bacteriostatic rate was more than 90%, and the antibacterial effect against Staphylococcus aureus was not good.The bacteriostasis rate of the fabric containing 5% nano-Mg-based powder against Escherichia coli and Staphylococcus aureus was more than 90%.
