In this study, a hybrid silica sol-gel embedded with a photochromic dye has been applied to wool fabric to form a photochromic
coating. The treated wool fabrics showed very quick photochromic response. Five different silanes have been used as the silica
precursor, and the resultant coating showed slight differences in photochromic performance, fabric washing fastness, and surface
hydrophilicity. However, the silica type had a considerable influence on fabric handle property. The silica matrix from the
silane containing a long alkyl chain had a very little influence on the fabric handle and better photochromic performance
than those from other different silane precursors. 相似文献

The abrasion behavior of three kinds of warp knitted fabrics, which are normally used for upper sole of footwear, was evaluated.
We measured the changes of mechanical and structural properties of each sample as abrasion cycle increased. Each sample showed
similar trends in compression and surface properties but there were significant differences in abrasion rate among the samples.
The mechanical properties showed remarkable differences with directions. The frictional coefficient (MIU) of fabric surface
increased at the beginning of abrasion and decreased as abrasion cycles increased. The weight and thickness of the fabric
linearly decreased with abrasion cycles. The surface roughness (SMD) and the compressional resilience (RC) decreased as abrasion
cycles increased while compressional energy (WC) increased. 相似文献
