The present invention relates to a smart textile capable of providing acupuncture therapy to the wearer through strategically positioned electrodes throughout the textile, connected via silver coated fabric. Through the instant invention, heat therapy can be applied to specific points on the body, while being safe due to the absence of wires.

A solute is precipitated from a solution of a solute, a solvent, and a non-solvent by preparing the solution and introducing the solution into a precipitation chamber contain a supercritical fluid.

Method for precipitating a solute from a solution

The present invention relates to a process of making biodegradable and/or bioabsorbable biomaterials and keratin nonwoven fibrous articles by electrospinning fibers from a blend of biomaterials and keratin dissolved in organic solvents includes generating a high voltage electric field between oppositely charged biomaterials and keratin fluid in a syringe with a capillary tip and a metallic collection roller and causing a jet to flow to the roller as solvent evaporates and collecting fibrous membranes or scaffolds on the roller. Keratin increased the cell affinity of biomaterial scaffolds which have potential medical applications.

The present invention relates a method of making a coated cellulosic textile, whereby a silk peptide is polymerized with a building block to develop a silk peptide/building block nanoparticle, said nanoparticle then being used to coat the textile. The resultant textile exhibits a high level of wrinkle recovery angle and/or tear strength, all without the use of N-methylol compounds, including ureas and formaldehydes.

The present invention relates to a method of enhancing the negative ion properties of a material and enhance its moisture management properties if necessary. The method of the present invention teaches the determination of the moisture properties of a material, development of a negative ion agent, and the application of that agent to the material, such steps leading to a material possessing negative ion properties and good moisture management.

A technique allowing manufacturers to produce woven moisture management fabrics with good moisture transfer properties is based upon a model of the fabric construction, thereby avoiding a manufacturing trial-and-error process. An initial woven fabric design including hydrophilic and hydrophobic yarns are modeled, the warp and weft yarns generally lying in a plane of the fabric. By orthographic projection onto respective planes substantially parallel to the plane of the fabric, a first view and an opposing second view of a unit cell of the model is produced. If the total projected area of hydrophobic yarn on one of the first and second views is between 40% and 70% of the total projected area, and total projected area of hydrophilic yarn on the other of the first and second views exceeds 50% of the total projected area, then a fabric according to the fabric design will have near optimum moisture wicking properties and is manufactured to the design. Otherwise, in an iterative process, one of the factors in the model is varied and the design steps repeated.

Woven fabric with moisture management properties

An integrated processing technique for preparing moisture management textiles or fabrics wherein fibers are treated with compositions which impart a hydrophobic or hydrophilic property such that when incorporated into the fabrication of composite structured textiles or fabrics a hydrophobic inner surface and a hydrophilic outer surface are formed. The integrated processing technique for preparing moisture management textiles also includes finishing the textiles or fabrics to enhance the fabric's liquid water one way transfer properties. The advantage of this invention is the possibility to manufacture the pure cotton woven/knit fabrics with the good moisture management properties.

Visual thermal functional textile clothing designs are created using a programmed computer and advanced computing techniques. The computer is supplied with information from a number of databases relating to human body properties and relating to textile material characteristics. The method is used to generate functional designs that are visually displayed for use by a textile designer or engineer.

A series of paraffin compounds, the phase change materials (PCMs), were microencapsulated in an interfacial polymerization process to form the double-shell microcapsules with relatively low shell permeability. The inner shell is formed through the reaction between polypropylene glycols and bifunctional polyisocyanates and the outer through the reaction between bifunctional polyisocyanates and polyamines added in the continuous aqueous phase. The so prepared microencapsulated paraffin compounds emulsion can be used as the medium for temperature management in many fields.

An apparatus for grinding an organic material into a powder includes a first grinding member with a first grinding surface and a second grinding member with a second grinding surface. The first and second grinding members are rotatably positioned adjacent each other for grinding an organic material between the first and second grinding surfaces. The first and second grinding surfaces include radii defining of sectors. The sectors include rows of teeth parallel to respective radii.

A composite textile fabric includes a composite layer of a hydrophobic material and a layer of a hydrophilic material knitted or otherwise formed together. The composite layer has an upper surface of small exposed areas of the hydrophilic material covering a total area about 25% of the overall area of the upper surface. The composite layer provides one way liquid transport for moisture, extending from the upper surface towards a lower surface of the composite layer.

A single fabric testing apparatus is capable of measuring mechanical and thermal characteristics of a specimen previously carried out in separate testing apparatuses. The single apparatus is provided with a plurality of mechanical and temperature sensors and a heatable top plate. In use, a ram moves the top plate vertically downwards to press a fabric specimen against a bottom plate. The plate is surrounded by a fixed upstanding peripheral skirt against which an outer periphery of the specimen is bent to enable shearing and bending characteristics to be measured. The bottom plate is biased upwards by a spring which is compressed until the top plate is arrested by a fixed frame member. Further downward movement of the ram enables compressibility of the specimen to be determined. A rotatable section of the top plate can be turned by a stepping motor to determine the surface friction characteristics of the specimen.

Textile fabric testing

Moisture management indexes are determined for a textile sandwiched between two plates. Electrical conductors arranged in concentric opposing pairs are used to measure changes in electrical resistance of the fabric. A quantity of water (or other chosen liquid) is poured down a guide pipe and changes of resistance measured against time. From this data, specific indexes are determined, in a repeatable fashion, and used for determining moisture management characteristics of the fabric.
