    Abstract: 959,627. Knitting. BURLINGTON INDUSTRIES Inc. Oct. 2, 1962 [Dec. 1, 1961, No. 37401/62. Heading D1K. Bare elastomeric polyurethane yarn is knitted into alternate courses of a compressive fabric with nylon body yarn of lighter weight than that forming the intervening courses, the polyurethane yarn being substantially embedded in the fabric. The polyurethane yarn which is non-foamed and may be mono- or multi-filament may be knitted circularly e.g. on a two or four feed machine. As shown the welt of stocking S is knitted at two feeders from two ends of 40 denier filament crimped or textured nylon yarn and the shadow welt 12 with two ends of 40 denier texturised yarn. When knitting the leg portion 14 the main feed supplies 40 denier raw nylon yarn (courses 22, 24, Fig. 2,) and the auxiliary station supplies 20 denier raw nylon yarn 26 and a bare 70 denier elastomeric polyurathane yarn 28 stretched approximately 225%. Alternatively, one feed may supply 50 denier raw nylon yarn while the other feed supplies either 30 denier raw nylon yarn and 70 denier polyurethane yarn or 20 denier raw nylon yarn and 140 denier polyurethane yarn. The ankle may be shaped by increasing the tension in the nylon yarn without altering the tension in the polyurethane yarn.
