Claims19
A tubular knit sleeve for a below-the-knee amputee, the tubular knit sleeve comprising:
- an open first end, a closed second end, and a tubular body extending between the first end and the second end;
- an upper grip band extending around a circumference of the tubular body adjacent to the first end, the upper grip band formed from an upper set of grip yarns having a denier per filament less than or equal to about 0.01;
- and
- a lower grip band extending partially around the circumference of the tubular body adjacent to the second end, the lower grip band located on a back aspect of the tubular knit sleeve, the lower grip band formed from a lower set of grip yarns having a denier per filament less than or equal to about 0.01;
- wherein the lower grip band comprises a single jersey knit structure with terry loops;
- and
- wherein the lower grip band further comprises a plating yarn comprising a 156 decitex spandex yarn covered with two strands of 78 decitex nylon.
A tubular knit sleeve for a below-the-knee amputee, the tubular knit sleeve comprising:
- an open first end, a closed second end, and a tubular body extending between the first end and the second end;
- a reinforcement zone positioned on a front aspect of the tubular knit sleeve adjacent to the second end of the tubular knit sleeve, the reinforcement zone comprising thermoplastic polyurethane (TPU) yarns;
- and
- a thermoplastic polyurethane (TPU) material deposited on an outer-facing surface of the reinforcement zone;
- wherein the reinforcement zone comprises a single jersey knit structure with terry loops using one strand of a 100 decitex TPU yarn in combination with a polyester body yarn comprising four strands of 167 decitex polyester.
A method of manufacturing a tubular knit sleeve for a below-the-knee amputee, the method comprising:
- knitting a tubular body having an open first end and a closed second end, wherein knitting the tubular body comprises:
- knitting an upper grip band that extends around a circumference of the tubular body adjacent to the first end, the upper grip band formed from an upper set of grip yarns having a denier per filament less than or equal to about 0.01;
- and
- knitting a lower grip band that extends partially around the circumference of the tubular body adjacent to the second end, the lower grip band located on a back aspect of the tubular knit sleeve, the lower grip band formed from a lower set of grip yarns having a denier per filament less than or equal to about 0.01;
- and
- wherein the lower grip band comprises a single jersey knit structure with terry loops;
- and
- wherein the lower grip band further comprises a plating yarn comprising a 156 decitex spandex yarn covered with two strands of 78 decitex nylon.
