Flat tops mainly consist of the flats fabric and of the hooks. Both of them have an enormous influence on carding quality. TCC uses a “multi-layer foundation” in the web construction, with the covering layer always consisting of a permanently elastic natural rubber. A flats fabric consists of up to seven single layers that are constructed like a sandwich. The wires used are made of micro-alloyed steel and are always additionally hardened by TCC. Computer-optimised, biconvex wire cross-sections and the special geometry of the tips (only half as wide as a cylinder wire) reduce wire movement during the carding process. Thus the so-called excessive breaking is reliably avoided.
