Abstract
The present invention generally relates to the production of knitted sweatbands that exhibit superior elasticity and breathability. Generally, the manufacturing process for producing the knitted sweatbands involves: (1) applying a continuous wax coating onto a polyester yarn; (2) twisting the yarn with one or more additional yarns to produce a twisted yarn; (3) knitting the twisted yarn into a sweatband body; and (4) finishing the sweatband body to form the sweatband. The sweatbands of the present invention can easily facilitate the movement of sweat away from the wearer, while still providing comfort and breathability.
Claims19
A process for the production of a sweatband, wherein the process comprises:
- (a) applying a wax onto a yarn to form a treated yarn, wherein the wax comprises a paraffin wax, a silicone oil, a white oil, and a rapeseed oil, wherein the yarn comprises at least one polyester filament;
- (b) twisting the treated yarn with at least one additional yarn to form a twisted yarn;
- (c) knitting the twisted yarn to thereby form a sweatband body;
- and
- (d) finishing the sweatband body to form the sweatband, wherein the finishing comprises ironing at least a portion of the sweatband body,
- wherein the wax comprises:
- (i) 25 to 95 weight percent of the paraffin wax, (ii) 1 to 50 weight percent of the silicone oil, (iii) 0.5 to 50 weight percent of the white oil, and (iv) 0.1 to 25 weight percent of the rapeseed oil.
A process for the production of a sweatband, wherein the process comprises:
- (a) applying a wax onto a yarn to form a treated yarn, wherein the yarn comprises at least two polyester filaments, wherein the wax comprises:
- (i) a paraffin wax, a silicone oil, a white oil, and a rapseseed oil,
- (ii) a weight ratio of the paraffin wax to the silicone oil, the white oil, and/or the rapeseed oil of at least 2:1,
- (iii) a weight ratio of the silicone oil to the white oil or the rapeseed oil of at least 1:1, and
- (iv) a weight ratio of the white oil to the rapeseed oil of at least 1:1;
- (b) twisting the treated yarn with at least one additional yarn to form a twisted yarn;
- (c) knitting the twisted yarn to thereby form a sweatband body;
- and
- (d) finishing the sweatband body to form the sweatband, wherein the finishing comprises ironing at least a portion of the sweatband body.
A knitted sweatband, wherein the knitted sweatband comprises a yarn containing one or more polyester filaments,
- wherein the polyester filaments comprise a plurality of lobes,
- wherein the polyester filaments comprise a transverse aspect ratio of at least 1.5:1,
- wherein the yarn is at least partially coated with a wax comprising:
- (i) a paraffin wax, a silicone oil, a white oil, and a rapeseed oil,
- (ii) a weight ratio of the paraffin wax to the silicone oil, the white oil, and/or the rapeseed oil of at least 2:1,
- (iii) a weight ratio of the silicone oil to the white oil or the rapeseed oil of at least 1:1, and
- (iv) a weight ratio of the white oil to the rapeseed oil of at least 1:1.
