后整理加工法是用具有一定耐洗性能的抗菌剂对织物进行后整理,使抗菌剂能够附着在织物上,使其具有抗菌功能的方法。该法工艺简单,因此是制备抗菌织物常用的加工方法。该法历史长,应用也为广泛。从古埃及人早用作保存木乃伊的抗菌整理剂开始,人类在漫长的历史过程中不断开发出一代又一代抗菌织物整理剂,加工工艺也越来越成熟。由于这种方法简便、损失少、受织物成形其它环节的影响小,可选择的抗菌剂范围较广等特点,一直受到生产厂家的青睐。目前对纺织品的抗菌防臭加工中,后整理法占70%以上。
1. Padding method</p
Pad the fabric with an antibacterial agent solution. When baking or evaporating by other methods, a layer of insoluble or slightly soluble matter will form on the fiber; or mix the antibacterial agent and resin to form an emulsion, put the fabric into it and fully soak it, and then Through rolling and drying, the resin containing antibacterial agents is attached to the surface of the fabric. �如以烷基或烷基酚聚乙烯醚为乳化剂,氯化石蜡为助剂对氯代二苯醚类抗菌物质进行乳化制成的抗菌整理剂就属此类� Commonly used antibacterial finishing agents also include silicone quaternary ammonium salts, biguanide-based organic nitrogen-containing compounds, quaternary ammonium salts plus cross-linking agents, diphenyl ethers, pyridine drugs, sulfonamide drugs, imidazole series and azole series heterocycles Antibacterial finishing agents composed of antibacterial drugs and cross-linking agents, etc. �</p
2. Dip method</p
将织物用抗菌剂溶液浸渍一定时间后,脱水烘干、烘焙处理得抗菌织物。这种方法要求抗菌剂与纤维有较强吸附力,抗菌剂在较低浓度即能被织物吸净。常用抗菌剂包括有机硅季胺盐系及双胍类有机含氮化合物等。
3. Coating method</p
将抗菌剂与涂层剂配成溶液对织物进行涂层处理。常用抗菌剂有磺胺药类、喃药类和有机硅季胺盐类等。前两类多用于处理棉麻等纤维,季胺盐类可用于化纤及天然纤维。
4. Spraying method</p
将抗菌剂配成溶液对织物进行喷洒处理。常用抗菌剂有磺胺药类、喃药类和有机硅季胺盐类等。前两类多用于处理棉麻等纤维,有机硅季胺盐类可用于化纤及天然纤维。
5. Microencapsulation method</p
将抗菌剂制成微胶囊,再用高分子粘合剂或涂层剂对织物处理� �抗菌剂需能适合粘合剂的加工条件且好能渗透到纤维无定形区以增强其耐洗涤性� �如日本钟纺公司将艾蒿提取物和扁柏提取物封入微胶囊中,对内衣、运动衫进行处理,产品具有较高的耐洗性�
