An article of manufacture and a method are disclosed including a multi-layered knee pad including an outer shell and other layers forming high sidewalls, the height of which depends on the internal width of the knee pad. The outer shell may also have an array of recesses on its outer convex surface. The other knee pad layers include one or more foam layers on the concave side of the outer shell, one or more gel layers surrounded by the foam layers, and a fabric sheet covering the foam layers on the concave side of the outer shell. The knee pad is manufactured using an injection mold to form the foam layers. The knee pad is customizable with respect to size, firmness, and structure. The knee pad may be customized by varying the layer's characteristics such as material and dimensions as well as the size and location of the recesses.

Multicolored flexible wearables include a first portion having a first flexible polymer forming a toroid and including colorant(s), an exposed first outer surface, an exposed second outer surface, and a recess in the first outer surface not reaching the second outer surface. A second portion formed of a second flexible polymer fills a majority of the recess and includes colorant(s). The first and second flexible polymers have different colors and are permanently bonded together. Precious material particles may be disposed within the first and/or second flexible polymers. One or more of the colorants may have a color matching a color of the precious material particles. One method of bonding the portions includes depositing a liquid second portion into the recess and then curing it. Another method includes depositing a solid second portion into the recess and then curing a liquid layer of polymer between the first portion and second portion.

A device for preparation of double fabric for down products comprises a printing means that can print an adhesive in a predetermined printing pattern on fabric; a drying means that can dry or fix the adhesive; a laminating means that can stack and laminate the fabrics on which an adhesive is printed; and a bonding means that can bond the fabrics with a cured adhesive by pressing with a predetermined pressing means and high-frequency heating to cure the adhesive; wherein said printing pattern and the pressing pattern are the same in pattern (shape), can be overlapped on the basis of the center line and have a difference in size (width) of 20% or less. Consequently, double fabric for down products thus manufactured has an excellent adhesiveness and durability and an aesthetically excellent pattern line with good clearness and finishing quality.

A process of manufacturing a down product comprises at least one bonding pattern line for the compartment separation without forming sewing holes by printing and drying a heat-reactive adhesive on the inner surface of an inner fabric, an optional mesh material and/or an outer fabric in a predetermined pattern, laminating said inner fabric, optional mesh material and/or outer fabric, and then high-frequency heating them under pressing with a pressing pattern the same as the printing pattern to bond the inner fabric, optional mesh material and outer fabric. Accordingly, it is possible to manufacture a down product having a bonding pattern line composed of a bonding line with excellent adhesiveness and durability and an aesthetically excellent pattern line with good clearness and finishing quality as well as to achieve a mass production of down products by mechanization and automation.

An apparatus for the thermo-forming and/or thermo-adhesive bonding of semi-finished products comprises: an oven (6) having walls (8, 9, 11, 12) delimiting a chamber (13) configured for housing at least one semi-finished product (4); devices (15, 16, 20) for generating a flow of heated fluid; wherein at least one of the walls (11) has a plurality of openings (19) in fluid communication with the devices (15, 16, 20). Baffles (23) and/or closing elements (24) are mounted near at least some of the openings (19). The baffles (23) are configured to divert the heated fluid leaving the openings (19). The closing elements (24) are configured to obstruct some of the openings (19). The baffles (23) and/or the closing elements (24) are movable with respect to the walls (11) and/or they are replaceable, in order to change conditions of the flow of heated fluid in the chamber (13).

Fabrication of ballistic resistant fibrous composites having improved ballistic resistance properties. More particularly, ballistic resistant fibrous composites having enhanced flexural properties, which correlates to low composite backface signature. The composites are useful for the production of hard armor articles, including helmet armor.

A multifunctional fabric, a fabricating method thereof and an outdoor garment are described. The multifunctional fabric comprises: a PTFE microporous membrane; wherein the PTFE microporous membrane is added with an inorganic nano luminescent material. In this way, after the fabric is made into garments, particularly when it is applied in outdoor sports garments, the inorganic nano luminescent material can absorb UV rays to make the garments glow, thereby not only improving aesthetics of the garments, but also reducing damage of the UV rays to human health. In addition, by adding the inorganic nano luminescent material in the PTFE microporous membrane, the problems of poor firmness and persistence of a single PTFE material can be overcome. Because the molecular bond of the inorganic nano luminescent material has high intensity and is stable, the multifunctional fabric will be durable after it is added with the inorganic nano luminescent material.
