摘要:文章介绍了一款利用烫印和贴合技术设计的抗菌保暖炭银面料,并对基布的选择、产品的规格、工艺流程、工艺参数和关键技术做了详细的介绍,然后将贴合好的面料参照标准对其抗菌性、撕破强力、水洗外观变化、耐磨性、保温性进行了测试。通过检测发现面料水洗后炭银层没有明显脱落,对金黄色葡萄球菌的抑菌率达97.9%,经向撕破强力为13.4N,纬向撕破强力为12.9N,耐磨性大于5000r,热阻为0.013m2·K/W,湿阻为25.1m2·Pa/W。由测试数据可知,所设计的功能面料符合标准的技术要求,达到了客户的使用需求。

The Design of a Charcoal/Silver Fabric with Antibacterial and Thermal Insulation Properties
Abstract: This paper introduced a charcoal/silver fabric with antibacterial and thermal insulation properties, which is made by using thermoprinting and laminating technologies. The selection of base fabric, product specifications, technological process, process parameters and key technologies were introduced in details and then the antibacterial property, tearing strength, appearance retention after washing, abrasion resistance, thermal insulation property of the laminated fabric were tested according to related standards. The test results show that there is no evident peeling-off of the charcoal/silver layer after washing, the anti-staphylococcus aureus rate of the fabric is up to 97.9%, the warp-wise tearing strength is 13.4 N, the weft-wise tearing strength is 12.9 N, the abrasion resistance is over 5,000 turns, the thermal resistance is 0.013 m2·K/W and the wet resistance is 25.1 m2·Pa/W. These data prove that the designed functional fabric meet both the technical requirements in related standards and customers requirements.

结合印刷品烫金工艺将炭银膜运用到机织四面弹面料上,可使面料不但具有蓄热保温、抗菌除臭特性,还兼具时尚、摩擦系数小、防风及弹性好等特点。本产品的开发采用活性炭粉涂于机织物表面。炭粉材料为生物材料,材料本身无毒无害,炭粉加入PU树脂可使衍生的纺织品具有吸湿、除臭、抗菌抑菌、负离子、抗紫外线、远红外线、蓄热保暖等功效。此外,PU树脂中还加入了银粉,银粉是“铝粉”的俗称,质轻、漂浮力高、遮盖力强,对光和热的反射性能好,还可以使衍生的纺织品具有蓄热保暖和超强的金属外观。
1材料与设备的选择
1.1机织四面弹基布规格
经纬纱原料:涤纶94%氨纶6%;
经纬纱线密度:75D+40D×75D+40D;
经纬密:480×430根/10cm;
克重:105g/m2;
织物组织:平纹。
1.2转印膜基材的选择
目前主要的热转印膜基材有OPP、PET、PVC、CP。OPP膜基材平滑透明度高,具有耐温耐候性,所以本产品采用加入炭粉和银粉的PU树脂通过OPP转印膜进行布面压印。……
