Abstract:
A polyurethane is dyed with an aqueous solution of an acid dye compound, a quaternary ammonium compound selected from soluble tetrabutylammonium compounds and tetrahexylammonium compounds, and, optionally, an water-soluble organic solvent.
Abstract:
Decorative foamed articles are prepared from foamed pellets, beads, particles, or other articles of a thermoplastic elastomer infused with a supercritical fluid in a pressurized container, then rapidly depressurized and heated either by immersion in a heated fluid that can rapidly heat the article or with infrared or microwave radiation to heat and foam the pellets, beads, particles, or other articles that are then molded into the articles. The pellets are dyed with a nonionic or anionic dye one of: (1) before being infused with the supercritical fluid, (2) during being infused with the supercritical fluid by a nonionic or anionic dye dissolved or dispersed in the supercritical fluid, which optionally comprises a polar liquid, (3) during immersion in the heated fluid, where the heated fluid contains the dye, or (4) after being foamed.
Abstract:
A foamed article is made by infusing an article of thermoplastic elastomer including a nonpolar component with a supercritical fluid, then removing the article from the supercritical fluid and either (i) immersing the article in a heated fluid or (ii) irradiating the article with infrared or microwave radiation.
Abstract:
A system and method for ball fitting is disclosed. The system and method may use a swing characteristics detector. A detector may be placed between a golf club face and a golf ball. The golf club may strike the golf ball, and a mark may be made on the swing characteristic detector. The mark may be evaluated to determine at least one swing characteristic. The swing characteristic may be used to select an appropriate golf ball for a golfer.
Abstract:
A thermoplastic golf ball material is made by combining and reacting (a) an unneutralized copolymer of ethylene and at least one of acrylic acid and methacrylic acid, which has from about 5 to about 12 percent by weight acid monomer; (b) a metallocene-catalyzed copolymer of ethylene and octene; (c) an unsaturated fatty acid; and (d) a metal cation in an amount sufficient to neutralize from about 65 to about 90% of the acid groups, to produce an ionomeric thermoplastic material. The ionomeric thermoplastic material may be used in a core, a cover, or a layer between a core and a cover of a golf ball.
Abstract:
A golf ball has a cover with a Shore D hardness of at least about 59 and a coating on the cover that has at least one of (a) a pencil hardness of 2B or less, (b) a Sward hardness of about 40 or less, or (c) a Hit (Young's Modulus) 0.55 micrometer
Abstract:
Golf club heads (102) include at least one part (200, 250) having a side wall extending completely around the club head, wherein the side wall ends at an edge (204, 254) that defines an open side of the part. An interior surface of this side wall has a draft angle of -1 °or more as it extends to its edge. In some club heads, the interior surface of at least one club head part will be shaped so that the interior surface does not converge as the side wall of that part extends to its edge. For some club head parts, the planar cross- sectional area defined inside the interior surface of the part can stay the same or get larger as one moves to the part edge. By avoiding or limiting features of negative draft angles, converging interior surfaces, and/or smaller cross-sectional areas on interior surfaces of a part, manufacturing and tooling may be simplified.
Abstract:
A golf ball of a first color is dyed to a second color with an anionic or nonionic disperse dye. Either or both of the cover or an optional clear coating layer on the cover comprises a member selected from the group consisting of polyurethanes, polyureas, polyamides, and combinations thereof, which can be dyed by the anionic or nonionic disperse dye.
Abstract:
A spacer textile material has at least a portion of a tensile strand located between a first layer and a second layer of the spacer textile material where the first layer and second layer have been joined together to form channels in which the tensile strand moves freely. The tensile strand may be disposed within or about the spacer textile material in any location on the material. The spacer textile material with a tensile strand may be incorporated into an article of footwear and/or article of apparel.
Abstract:
An article of apparel (100) may include a garment component (110) and a pad component (300). A pair of linear regions of the pad component may be secured to -the garment, and a region of the pad component between the linear regions may be unsecured to the component. The pair of linear regions may be positioned at spaced and separate edge areas of the pad component. A central area of the pad component may be at least partially spaced from the garment component when the garment component is substantially unstretched.
