The present invention is a softening base agent containing a compound represented by the following formula 1:

##STR00001## wherein each of R.sup.1 and R.sup.2 represents a hydrocarbon group with 6 or more and 24 or less carbons, and the total number of carbons in R.sup.1 and R.sup.2 is 18 or more and 30 or less; and M is a cation, excluding a hydrogen ion.

The present invention discloses means, and systems utilizable in a method for converting post-consumer cellulose-containing (e.g., cotton) textile waste (ctPCR) to nanocellulose, derivatives, and products thereof, comprising steps as follows: grinding said ctPCT; suspending the ground ctPCR in basic pH hydrophilic slurry; and exposing the same to ozone gas.

A method of manufacturing a functional fabric includes the steps of: (a) providing an undyed base fabric having a top surface and a bottom surface opposite to the top surface; (b) forming a moisture-permeable waterproof layer on the top surface of the base fabric; and (c) forming at least one pattern layer on at least one of the moisture-permeable waterproof layer or the bottom surface of the base fabric.

A woven fabric comprising spun synthetic polyamide yarn woven in the warp direction and weft direction wherein the polyamide yarn in the woven fabric exhibits a formic acid relative viscosity of at least 60, a halide:copper molar ratio of at least 2.0 and a sodium content of no more than 25 ppm, and wherein the woven fabric exhibits a melt-through resistance at 450° C. of least 2.10 seconds. The invention also provides an airbag made the woven fabric, as well as a method of making the same.

Disclosed is a method for manufacturing a polyester fabric for an airbag that can not only prevent or minimize the separation of a sizing agent, which is provided to a yarn through a sizing process, during a weaving process, but can also maximize a peel strength between a textile substrate and a coating layer to be subsequently formed thereon and lower the stiffness of an airbag fabric by effectively removing the sizing agent from the textile substrate after the weaving process is completed. The method of the present invention comprises: applying a polyester-based sizing agent to a polyester yarn; manufacturing a textile substrate with the sizing agent-applied polyester yarn; removing the sizing agent from the textile substrate under an alkaline condition of pH 8 to 10; and forming a coating layer on the sizing agent-removed textile substrate in order to enhance air-tightness.

A method of preparing a fiber for use in forming a ceramic matrix composite material comprises the steps of removing a polymer coating from an outer surface of glass or ceramic fibers by providing heated and humidified gas across the glass or ceramic fibers for a period of time.

A method of manufacturing an elastic fabric including a latent crimped yarn according to an embodiment includes forming a raw fabric by knitting the latent crimped yarn and a polyester yarn, reducing the raw fabric, removing oil from the raw fabric, removing wrinkles of the raw fabric, followed by drying, dyeing the raw fabric, and removing wrinkles of the raw fabric, followed by drying to form the elastic fabric. The method can manufacture a highly elastic fabric having excellent recovery and color fastness to washing.

The present invention relates generally to compositions and methods for oxidizing or discoloring garments, such as denim. Another aspect relates to providing a cost-effective and environmentally safe alternative to hazardous bleaching agents, such as potassium permanganate.
