Disclosed are hollow fibers suitable for use in dialysis in an outside-in configuration. For such fibers, it is desirable that the fiber have a low albumin sieving coefficient and have a permeability high enough to be considered a High Flux dialyzer, and it is desirable that the outer (blood-facing) surface have a sufficiently small roughness and be hydrophilic. It is desirable that there be a selective layer on the outer surface and, interiorly of that, a porous structurally supportive region, which may contain elongated macrovoids. Such a fiber may be spun through a triple-concentric spinneret that produces a bore liquid surrounded by dope surrounded by a shower. The shower and the coagulation bath may be pure water, which is a non-solvent. The process may be performed at room temperature. Spinning parameters are discussed.

A bimorph meta fiber is formed through spinning of two antagonistic polymer melts, one of which contains pre-compounded optical nanostructures, into an eccentric sheath-core configuration or a side-by-side key-lock configuration. The bimorph meta fiber is capable of an adaptive regulation of the infrared radiation responsive to humidity level deviation from a comfort zone or perspiration level of the wearer of the garment fabricated from the meta fibers. The bimorph meta fibers are humidity/heat trained to attain dynamical environmentally responsive behavior to maintain the humidity/thermal comfort zone at various the humidity level fluctuations.

Embodiments of the invention disclosed herein are directed to articles of clothing that allow for monitoring of different analytes (e.g., electrolytes and molecules) in human sweat during fitness activity, while training, or simply in everyday life. The clothing includes a sensor system completely integrated in textile such that every sensing part is made of textile fibers. The clothing is able to control, collect, analyze, and expel the sweat over time. The textile sensor allows a spontaneous absorption of body sweat directly from the skin, while it is produced, using the hydrophilic natural properties of the textile. Then, once adsorbed, the flux of sweat is controlled and guided through the textile using a gradient of the textile's hydrophilic properties. The sweat guided through the textile is analyzed through an electrochemical sensor woven into the textile. Finally, the sweat is collected in a reservoir and expelled for evaporation.

A method of manufacturing a double-layer knitted fabric such as a compression article is provided. The method is performed on a knitting machine having at least two needle beds. The knitted fabric includes an outer layer made of a hydrophilic yarn on the first needle bed and an inner layer made of a hydrophobic yarn on the second needle bed. The method includes a. Forming of stitches with a hydrophilic yarn with all needles of the first needle bed and with selected needles of the second needle bed; b. transferring the stitches made of the hydrophilic yarn and formed on the selected needles of the second needle bed to needles of the first needle bed; c. immediately after transferring the stitches, forming of stitches with a hydrophobic yarn on the selected needles of the second needle bed as well as with all other needles of the second needle bed.

The invention relates to a wearable garment and methods for preventing fungal type infections.

Disclosed are a highly absorbent composite fiber, a highly absorbent non-woven fabric, and an article including the non-woven fabric. The disclosed highly absorbent composite fiber includes: a core including a polyolefin-based resin; and a sheath including ethylene vinyl alcohol (EVOH) resin.

Provided are a hydrophilic fabric and a manufacturing method thereof. The hydrophilic fabric has a structure in which warp yarns and weft yarns are interwoven with each other, wherein at least one of the warp yarns and the weft yarns includes carbon nanotube fibers, the carbon nanotube fibers contain N-doped carbon nanotubes, the nitrogen content in each of the N-doped carbon nanotubes is between 1 at. % and 10 at. %, and the content of the N-doped carbon nanotubes in the hydrophilic fabric is at least 1 wt. % based on the total weight of the hydrophilic fabric.

An absorbent ecological fabric is provided, including: at least one first fiber element, each of the at least one first fiber element being absorbent and elongate, each of the at least one first fiber element being woven by a plurality of filaments. The absorbent ecological fabric can provide a large region for plants to attach and climb.

A knitted or woven fabric with moisture management function is described that includes an inner layer having a first yarn that is semi-hydrophilic with a first moisture regain, and an outer layer having a second yarn that is hydrophilic with a second moisture regain greater than the first moisture regain of the first yarn. The fabric has a moisture regain gradient between the inner layer and the outer layer that acts to pull moisture through the inner layer in contact with the wearer’s skin and out through the outer layer. In one embodiment, the second yarn is a combination of a core bi-component yarn and at least one outer sheath yarn surrounding the core bi-component yarn.

Examples of a knitted or woven fabric with moisture management function are described, comprising a face fabric layer with a durable water repellency (DWR) additives forming a fabric outer surface that is hydrophobic and a back fabric layer comprising a second yarn that is highly hydrophilic forming a moisture regain core to absorb the moisture and spread it across on an inside surface of the back fabric layer. The outer (face) layer of the fabric is hydrophobic due to the added DWR additives to the first yarn while the inner (back) layer of the fabric is highly hydrophilic that absorbs and spreads the moisture across the inner side of the back layer so that it dries faster making the outer surface of the face fabric layer dry thus reducing the occurrence of water/liquid spots on the face layer outer surface.
