1618 results about "Textile fiber" patented technology

In textile arena; textile fiber is the raw materials to produce various types of textile finished products. A fiber that can be spun into yarn or processed into textile such as a woven fabric, knit fabric, lace, felt, non-woven etc by means of an appropriate interlacing method is called as textile fiber.

Textile dyeing wastewater advanced treatment recycling technology

The invention discloses a textile dyeing wastewater advanced treatment recycling technology. The technology comprises the following steps: filtering to remove textile fibers; cooling; neutralizing, degrading organic matters and decomposing, replacing or degrading (cracking) the chormophoric groups of the organic matters to reduce the chroma of the wastewater; performing biochemical treatment with the biomembrane; precipitating to ensure that the precipitated sludge enters a sludge treatment system and the supernatant enters a flocculation pool; performing chemical treatment, namely adding a medicament in the flocculation pool to remove the suspended matter (SS), CODcr (chemical oxygen demand), BOD (biochemical oxygen demand) and chroma of the water; performing secondary precipitation to ensure that the free SS is precipitated and the wastewater is decolored further; separating to remove and degrade the chloride ions of the reuse water; performing secondary biochemical treatment to further reduce the concentrations of the SS, CODcr and BOD in wastewater; performing ozone oxidation treatment, decoloring, degrading organic matters; performing chemical treatment to remove insoluble dye materials and SS and reduce the COD and chroma; and performing secondary filtration, and forming an ozone/activated carbon system to ensure that the hydroxyl radicals of activated carbon are used and the organic reaction in wastewater is adopted to decolor and degrade organic matters. The invention overcomes the defects of the existing physical method, chemical method and chemical method treatment technologies; and the technology has been used in many enterprises, and the good treatment effects are obtained.

Cored piezoelectric fiber fabric

The invention relates to a fabric made of cored piezoelectric fibers by weaving or knitting. A plurality of cored piezoelectric fibers are parallelly woven or knitted along a same straight line or curved line direction, crosswise woven or knitted along different straight line or curved line directions, or woven or knitted to form knots extending in the straight line or curved line direction to form an area with the cored piezoelectric fibers, and the area with the cored piezoelectric fibers is woven or knitted with an area formed by weaving or knitting other textile fibers to form one or more layers of the fabric. Thus, the area with the cored piezoelectric fibers in the fabric can serve as a sensor or drive. Due to flexibility and foldability, the cored piezoelectric fiber fabric can be made into wearable structures such as gloves, vests, wrist bands, ankle pads, socks and the like which can be put on a living body or a robot body to serve as sensors for sensing health conditions in the living body, movements of the living body or the robot body or external acting forces; the wearable structures can also serve as drives for adding external signals onto the fabric, the living body can sense the external signals by sensing deformation, vibration and the like of the fabric; the wearable structures can further serve as sonic sensors or sonic drives to sense external sound waves or transmit sound waves.

Preparation method for flexible and highly-conductive composite carbon fiber cloth

The present invention relates to the field of carbon composite materials, more particularly to a preparation method for the flexible and highly-conductive composite carbon fiber cloth, wherein the pure natural cellulose cloth is adopted as a precursor to be uniformly compounded with carbon nanotubes and/or graphene through the impregnation method. In the protective atmosphere, textile fibers are carbonized through the high-temperature heat treatment, and a carbon fiber interface is strongly bonded with the composite carbon nanotubes or the composite graphene. In this way, during the carbonizing process, a strong bonding action is formed between carbon fibers, carbon nanotubes and/or grapheme, so that a coaxial carbon fiber cloth composite structure is formed. According to the invention, the structure and the performance of the composite material are regulated at different treatment temperatures, different treatment times and different compound quantities of carbon nanotubes. In this way, by means of the flexible and highly-conductive composite carbon fiber cloth, the problem that conventional carbon materials do not have the advantages of flexibility, high specific surface area and high electrical conductivity at the same time can be solved.
