摘要
为了改善丝绸的透湿性能,以γ-缩水甘油醚氧丙基三甲氧基硅烷(KH560)、正硅酸乙酯(TEOS)为前驱体,固体酸对甲苯磺酸为催化剂,合成有机硅溶胶,并对皱纹类丝绸进行改性。利用扫描电子显微镜、织物透湿仪、电子织物强力仪,激光织物折皱弹性测试仪等,对改性后的丝绸的透湿性等进行测定和分析。结果表明:当TEOS的质量分数为2%,偶联剂的质量分数为2%时,制备的有机硅可与丝绸很好地结合,丝绸的透湿性得到明显改善,且其他力学性能、透气性能等有所改善或基本不变,显示用该方法改性丝绸、制备高透湿性丝绸具有可行性。
To improve the moisture-penetrability of silk,γ-glycidyl ether oxygen propyl-group trimethoxy- silane （KH560） and silicic acid ethyl ester （TEOS） are used for presoma. Besides, solid acid p-toluenesulfonic acid is used as catalyst to compound organic silica sol to improve the performance of wrinkle-type silk. This thesis adopts scanning electron microscope, fabric breathable equipment, electronic fabric strength tester and laser tester for fabric cockle elasticity to detect and analyze the moisture-penetrability of the improved silk. According to related results, when both the concentration of TEOS and the concentration of coupling agent are 2 %, the prepared organosilicon can combine with silk better, the moisture-penetrability of silk is improved obviously, other mechanical properties and mechanical properties are improved or remained, which showed that this method is feasible to improve the performance of silk and prepare silk with high moisture-penetrability.
