Colorcontrasts

37、often occur when printed fabrics are snagged. D 3939,D 5362constant-rate-of-extension tensile testing machine (CRE),na testing machine in which the rate of increase of thespecimen length is uniform with time. D 6797constant-rate-of-extension type tensile testing machine(CRE), nin tensile testing, an
