Fabric treatment method for stain release
10822577 · 2020-11-03 ·

A fabric treatment composition is provided that includes at least one zeta potential modifier, a fluoropolymer and a hydrophobic agent with a melting point or glass transition temperature below 100 C., for imparting fabric protection benefits to a fabric, such as improved stain and soil resistance, oil repellency, water repellency, softness, wrinkle and damage resistance, and better hand feel. Fabric treatment compositions can be used as a pretreatment prior to washing, through soaking, or added to the treatment liquor, that is either the wash or rinse cycle of an automatic washing machine, to first provide and then maintain and refresh the fabric protection benefits imparted to the fabric, with the proviso that an intermediate rinsing step essentially devoid of added surfactant-is used after the washing cycle and prior to the fabric treatment step. Following use of a first treatment composition, protective benefits are maintained and refreshed by means of a second treatment operation employing a second treatment composition. The second treatment composition may have lower active levels of the protective agents to provide for economical and periodic maintenance of the imparted fabric protection benefits.

A laundry additive composition is provided that includes at least one zeta potential modifier, a fluoropolymer, a hydrophobic agent with a melting point or glass transition temperature below 100 C., and an antimicrobial active for imparting fabric protection benefits to a fabric, such as improved stain and soil resistance, oil repellency, water repellency, softness, wrinkle and damage resistance, and better hand feel, as well as imparting microbiocidal or microbiostatic properties to the fabric and/or washing machine surfaces. Laundry additive compositions can be used as a pretreatment prior to washing, through soaking a fabric or garment. Alternately, they can be added to a washing treatment liquor that comprises either the wash or rinse cycle of an automatic washing machine, to first provide and then maintain and refresh fabric protection benefits imparted to the fabric. Following use of a first treatment composition, protective benefits are maintained and refreshed by means of a second treatment operation employing a second treatment composition. The second treatment composition may have lower active levels of the protective agents to provide for economical and periodic maintenance of the imparted fabric protection benefits and/or refresh the microbiocidal or microbiostatic properties imparted to fabrics and/or washing machine surfaces.

Process for producing a knitted sweatband
10750804 · 2020-08-25 ·

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.
