PROCESS OF MAKING MULTICOMPONENT FIBERS
A process for making a multicomponent fiber is disclosed. The process comprises extruding at least one water dispersible polymer to create a first polymer flow, extruding at least one water non-dispersible synthetic polymer to create a second polymer flow path, directing the resulting multiple polymer flows into a spinneret having a shaped cross section with a plurality of distribution flow paths, and combining the flow paths together to form a multicomponent fiber having a shaped cross section, wherein the multicomponent fiber comprises: (A) at least one water dispersible polymer; and (B) a plurality of domains comprising one or more water non-dispersible polymers, wherein the domains are substantially isolated from each other by the water dispersible polymer intervening between the domains; and wherein the water dispersible polymer is present at the perimeter of the outside cross-section of the multicomponent fiber in a proportion of no greater than 55% water dispersible polymer.
PROCESS OF MAKING TEXTURED MULTICOMPONENT FIBERS
A process for texturing a multicomponent fiber is provided. The process comprises: (A) providing a multicomponent fiber having a shaped cross section and at least one water dispersible polymer; and a plurality of domains comprising one or more water non-dispersible polymers, wherein said domains are substantially isolated from each other by said water dispersible polymer intervening between said domains; and wherein the water dispersible polymer is present at the perimeter of the outside cross-section of the multicomponent fiber in a proportion of no greater than 55% water dispersible polymer; and (B) passing the multicomponent fiber through a first zone comprising a first heating device and a twisting unit, wherein the first heating device has a heating temperature that is at least 10% less than the temperature used for a fiber without the water dispersible component having the same water non-dispersible polymer, same number of total filaments in the fiber, and the same total denier for a given type of equipment and process conditions.
Lacrosse head pocket and related method of manufacture
A lacrosse head pocket and a related method of manufacture are provided to facilitate consistent, repeatable and/or custom manufacture of lacrosse equipment. The pocket can be constructed from multiple different sections joined with one another, or can be knitted, weaved or otherwise assembled on an automated assembly machine from strands, and/or can be formed as a unitary textile material having regions/sections with different physical and/or mechanical properties. The pocket can be integrally molded within portions of a lacrosse head to eliminate manually constructed connections between the pocket and lacrosse head. The lacrosse head can be integrally molded with a lacrosse handle to provide a one-piece unitary lacrosse stick. Related methods of manufacturing also are provided.
SINGLE PIECE HAMMOCK STRAP WITH INTEGRAL WOVEN EYELETS
This disclosure generally relates to a hammock strap. The hammock strap includes an elongated length of strap material that is separated into a first strap and a second strap. The first strap and the second strap are woven together at one or more separation points to form eyelets between the first strap and the second strap.

Tufted structure for landscape and sports
The present invention seeks to provide a tufted structure such as an artificial turf, that imitates more closely the root zone, the volume effect, and density of natural grass and that has an improved wear and drainage property. An artificial turf adapted for use in landscape and sports applications comprises a bounded layer of fibers formed as a non-woven matting made of one or more natural and/or synthetic fibers. A plurality of tufts of pile yarn is inserted through the bounded layer of fibers. A backing is applied at the backside of the bounded layer of fibers enhancing anchoring the tufts to the bounded layer of fibers.
SINGLE PIECE HAMMOCK STRAP WITH INTEGRAL WOVEN EYELETS
This disclosure generally relates to a hammock strap. The hammock strap includes an elongated length of strap material that is separated into a first strap and a second strap. The first strap and the second strap are woven together at one or more separation points to form eyelets between the first strap and the second strap.
SKIN-CORE STRUCTURE FIBERS WITH BOTH INFRARED AND RADAR STEALTH, PREPARATION METHOD THEREFOR, AND USE THEREOF
Skin-core structure fibers with both infrared and radar stealth, a preparation method therefor, and the use thereof are provided. The fibers are as follows: a core material of the skin-core structure fibers comprises the following raw materials in parts by weight: 10 parts of paraffin; 0.7-1.5 parts of an electromagnetic wave absorbent; and 1 part of a high-molecular polymer, wherein the electromagnetic wave absorbent is one or more of ferroferric oxide-intercalated graphene oxide, nano ferroferric oxide and carbon black, and wherein the skin-core structure fiber is obtained by spinning the core material with a skin-layer material.
ADJUSTABLE SPORTS ROPE
An adjustable sports rope comprised of a hollow base rope sheath and an adjustment rope. The hollow base rope sheath is a hollow sheath with at least two openings. The adjustment rope enters into the hollow base rope sheath through one of the at least two openings and exits the base rope sheath through another of the at least two openings. The one end of the hollow base rope sheath terminates at a tie point. The end of the adjustment rope disposed furthest from the hollow base rope sheath tie point is also a tie point. By creating a tensile force between the tie point of the hollow base rope sheath and the tie point of the adjustment rope, the hollow base rope sheath will tighten on the adjustment rope, holding the adjustment rope in place.
Composite sporting equipment
A sporting equipment is disclosed. The sporting equipment may include a barrel, an action connected to a base end of the barrel, and a stock connected to the action opposite the barrel. At least two of the barrel, the action, and the stock are fabricated from a plurality of fibers.
