- Abstract
Two alkoxysilane sols were prepared from 'Y-aminopropyltriethoxysilane ( APTES ) and ?-glycidyloxypropyltrimethoxysilane ( GPTMS), respectively. Compared with that treated with the GPTMS sol in one bath process, wool fabrics were treated with APTES and GPTMS sols in two bath processes. The composite sol and its gel were examined with TG and solid NMR. Results showed that the condensation rate of the APTES/GPTMS composite sol was significantly faster than that of the GPTMS sol. The epoxide rings in the GPTMS gel were opened only to a small extent. Most Si-0- condensate to three-dimension netted structure, and a small amount of them were linear structure. However, structure of the composite gel was denser, most epoxide groups undergo the ring opening reaction, three-dimension netted T³ was main structure in the gel. Hence, compared with the GPTMS gel, fabric treated in two bath process can obtain better anti-felting property (area shrinkage!. 4% ) at lower annealing temperature ( 120 °C:).
