  • Circular knitted fabric with finished edges and integral elastic band-like selvedge and the method of manufacturing the same
    Patent number: 8490436
    Abstract: A circular knitted fabric for the manufacture of a garment includes a first group of courses formed of a low melting point yarn and a first yarn, and a continuing second group of courses formed of the low melting point yarn and a second yarn. The second group of courses has an elastane content greater than that of the first group of courses. The low melting point yarn fuses with the first and second yarns after heating to a temperature sufficient to melt the low melting point yarn only. The fabric, after finishing, is adapted to be cut into a garment in such a way that the first group of courses becomes a body or the first group of courses of the garment, and the second group of courses becomes an integral elastic band portion or the second group of courses-like selvedge of the garment.
