FLAT-KNITTED THREE-DIMENSIONAL FABRIC WITH INTERNAL SUPPORT STRUCTURE, AND METHOD FOR PREPARING SAME
A flat-knitted three-dimensional fabric with an internal support structure, and the fabric is consisted of an upper surface layer, a lower surface layer, and a support structure yarn in a middle, wherein the upper surface layer and the lower surface layer comprise alternate-knitted single-sided stitches and fully-knitted single-sided stitches; the upper surface layer and the lower surface layer are connected by means of tuck knitting of the support structure yarn in the middle to form the integrally formed three-dimensional fabric with an internal support structure; and the alternate-knitted single-sided stitches are correspond to tuck loops formed by the support structure yarn and are used to lock the tuck loops formed by the support structure yarn in the middle, such that the support structure yarn will not puncture the surfaces of the fabric when the fabric is pressed.
Woven prosthesis and method for manufacturing the same
A woven prosthesis, such as a woven vascular graft, woven from warp and weft yarns. Velour warp yarns forming the prosthesis are selectively incorporated into a base layer of the prosthesis so as to provide a bulbous section without compromising the porosity of the prosthesis.
Lightweight, permeable garment formed from monofilament yarns
Aspects herein relate to a knit textile or garment that comprises at least a first and second portion. The first portion comprises a first percentage by weight of a first yarn and a second yarn. The second portion comprises a second percentage by weight of the first yarn and the second yarn. The two portions are integrally knitted from each other. The second portions provide a high level of air permeability, while the first portions provide moisture wicking and may be used as modesty portions in garments.
MOISTURE TRANSFER YARN AND FABRIC
A moisture transfer yarn blend and fabric containing a selected of engineered shaped, lobed, deep grooved, channeled, hollow, sheath-core, bi-component polymer silver fibers and bi-component polymer fibers, optionally blended with cylinder or round fibers or natural fibers or a combination. The engineered shaped, lobed, channeled and deep grooved polymer fibers have indentations along the longitudinal side of the fibers. The deep grooved fibers have four to eight deep indentations along the longitudinal side of the fibers and containing grooves in the deepest portion of the indentation.
DOUBLE KNIT FABRIC
A double-knit fabric containing a first knit layer, a second knit layer, and a plurality of stuffer yarns. The stuffer yarns are located between the first knit layer and the second knit layer. The double-knit fabric contains a plurality of anchored regions and a plurality of detached regions. In the anchored regions, the first and second fabric layers are knitted together and in the detached regions the first and second fabric layers are unattached. The average peak distance between the first and second fabric layers in the detached regions is at least about 3 mm and the double-knit fabric has between about 10 and 30 detached regions per square inch. The anchored regions contain at least two knit stitches in at least one direction and the anchored regions have a width of at least about 1 mm.
Algae-derived flexible foam, and a method of manufacturing the same
This document presents algae-derived antimicrobial fiber substrates, and a method of making the same. The fiber may be a synthetic fiber, but can also be formed as a cellulosic (e.g., cotton). In various implementations, an algae-derived antimicrobial fiber substrate can be made to have identical properties and characteristics of nylon-6 of nylon 6-6 polymer or the like, and yet contain antimicrobial, anti-viral, and/or flame retardant algal derived substances. Any of various species of red algae, brown algae, blue-green algae, and brown seaweed (marine microalgae and/or macroalgae) are known to contain a high level of sulfated polysaccharides with inherent antimicrobial, antiviral, and flame-retardant properties, and can be used as described herein. Additionally disclosed are algae-derived flexible foams, whether open-cell or closed-cell, with inherent antimicrobial, antiviral, and flame resistant properties. Further, a process of manufacturing is presented wherein the process may include one or more of the steps of: harvesting algae-biomass; sufficiently drying the algae biomass; blending the dried algae biomass with a carrier resin and various foaming ingredients; adding an algal-derived antimicrobial compound selected from various natural sulfated polysaccharides present in brown algae, red algae, and/or certain seaweeds (marine microalgae); and adding a sufficient quantity of dried algae biomass to the formulation to adequately create a fire resistant flexible foam material.
POROUS CARBON FIBERS REINFORCED RUBBER COMPOSITES
A rubber composition includes a rubber matrix and carbon fibers dispersed within the rubber matrix. The carbon fibers define a plurality of pores distributed throughout the carbon fibers and a surface chemistry including doped nitrogen and doped oxygen. The rubber composition also may include a plurality of additives selected from a crosslinking agent, at least one activator, and at least one accelerator, among others.
STIMULUS-RESPONSIVE MESH
This disclosure relates to a stimulus-responsive mesh made from hydrogel fibers that provide varying degrees of ventilation depending on environmental conditions. The hydrogel fibers may be arranged into a mesh with openings that change size depending on the degree of swelling of the hydrogel fibers. As the hydrogel fibers of the mesh change (e.g., from a contracted state to/from a swollen state), fluids may flow through the mesh at a variable flow rate that depends on the degree of swelling. The swelling of the hydrogel fibers may be responsive to changes in the ambient environment experienced by the mesh, including, for example, the moisture level at the mesh, the temperature level of the mesh, the chemical composition of the moisture incident the mesh, the presence of magnetic/electric fields near the mesh, and/or the light level at the mesh. In this manner, the ambient environment may determine the degree of swelling of the hydrogel fibers, and changes in the environment may cause moisture to be actively expelled from the mesh. The stimulus-responsive mesh may be used in a variety of products and may be particular useful, for example, for outdoor products such as bicycle helmets, tent screens, and outdoor clothing.
WATER VAPOR-PERMEABLE COMPOSITE MATERIAL
A composite material contains a nonwoven layer (i) which contains fibers formed from a first thermoplastic elastomer having meshes with a mesh size in the range from 10 to 100 μm, and a membrane layer (ii) which contains a second thermoplastic elastomer and having a layer thickness of less than 30 μm. The membrane is either pore-free (ii.1) or is porous and has pores with an average pore diameter of less than 2000 nm (ii.2). The membrane (ii) is at least partially in direct contact with the fibers of the nonwoven layer (i) and covers the mesh openings in the nonwoven layer (i) at least partially. The fibers of the first nonwoven layer (i) and the membrane (ii) in the contact area are at least partly joined to one another in an interlocking manner.
Three-dimensional medical implant
The present disclosure relates to a three-dimensional, degradable medical implant for regeneration of soft tissue comprising a plurality of volume-building components and a mesh component which is substantially made of monofilament or multifilament fibers, wherein each volume-building component is attached to at least one point on a surface of the mesh component, and wherein the projected surface area of each volume-building component, when projected on the surface of the mesh component, corresponds to a maximum of one tenth of the surface area of the mesh component.
