The present invention related to a method of for the production of textile articles, I which the textile articles can be disassembled automatically or semi-automatically, in which, when sewing or stitching, a polymer melt yarn is used.

3D fabrics have multiple layers including an outer dimensional layer of traditional fabric and a liner layer integrated with outer layer. The 3D fabrics have variable depth, typically ranging from between about 0.25 inches to about 2.0 inches. The 3D fabrics are produced from a molding process that creates the outer dimensional layer while adhering it to the liner layer. The 3D fabrics have unique visual properties which make them desirable for a variety of applications.

A mat seal for an electrical connector includes a plurality of through-holes extending in a through-hole direction through the mat seal, a grid of a first material having a plurality of grid meshes, the grid is arranged with the through-holes extending through the grid meshes, a first material layer of a second material disposed on a first side of the grid, and a second material layer of a third material disposed on a second side of the grid opposite the first side. The first material of the grid has a greater compression modulus than the second material of the first material layer and the third material of the second material layer.

The invention relates to a filament, made from a polymer composition comprising:at least 40 to at most 90 percent by weight of a first biodegradable polymer; and,at least 10 to at most 60 percent by weight of a second biodegradable polymer; wherein the percentage by weight is expressed compared to the total weight of the polymer composition; and, wherein the visual degradation speed of the first biodegradable polymer is faster than the visual degradation speed of the second biodegradable polymer when in contact with soil under the same conditions.

The present invention is an apparatus and method for volumetric reduction of polymeric material and in particular synthetic polymeric textile materials. Such materials are typically used in hospital operating rooms and have material memory meaning that they re-expand after compression. Consequently they are difficult to process as waste material. The present invention is a method and apparatus for thermally compacting a polymer comprising a first and second heated surface inclined downwardly towards each other and providing with a passage at their lower ends through which melted polymeric material may pass.

Described is a mold for generating a pattern of indentations in a surface of a thermoplastic textile, including at least one subunit adapted to create at least one subpattern of the pattern, wherein the at least one subunit is at least one of exchangeable or reconfigurable. A spatial arrangement of the at least one subunit is reconfigurable within the mold.

Methods, systems, and devices for extrusion-based three-dimensional printing are provided. The methods, systems, and devices allow for the printing materials such as fabrics, clothing, and wearable and/or implantable devices. A number of different enhancements are provided that allow for this improved form of three-dimensional printing, including: (1) printing using a polymer (e.g., cellulose acetate) dissolved in a solvent (e.g., acetone); (2) selectively bonding portions of a deposited filament onto one or more surfaces and/or one or more previously deposited filaments; (3) using particular toolpaths to create a fabric or similar material by creating a woven pattern; and (4) printing across multiple layers even when previous layers are not complete. Other aspects of the present disclosure, including other enhancements and various printer configurations, are also provided.

The present invention is directed at a relatively high modulus spunbond nonwoven material that is suitable for use in relatively high deep draw molding applications.

A method of creating a soft and lofty continuous fiber nonwoven web is provided. The method includes providing a first molten polymer and a second, different molten polymer to a spinneret defining a plurality of orifices and flowing a fluid intermediate the spinneret and a moving porous member. The method includes using the fluid to draw the first and second molten polymer components, in a direction toward the moving porous member, through at least some of the plurality of orifices to form a plurality of individual continuous fiber strands. The method includes depositing the continuous fiber strands onto the moving porous member at a first location to produce an intermediate continuous fiber nonwoven web, and intermittently varying a vacuum force applied to the moving porous member and to the intermediate web downstream of the first location and without the addition of more continuous fibers and without any heat applied.

A system for preparing a polylactic acid (PLA) spunbond nonwoven fabric is provided. In particular, the system includes a first PLA source configured to provide a stream of molten or semi-molten PLA resin; a spin beam in fluid communication with the first PLA source, the spin beam configured to extrude and draw a plurality of PLA continuous filaments; a collection surface disposed below an outlet of the spin beam onto which the PLA continuous filaments are deposited to form the PLA spunbond nonwoven fabric; a first ionization source positioned and arranged to expose the PLA continuous filaments to ions; and a calender positioned downstream of the first ionization source.
