A flash spinning method for preparing non-woven fabrics based on microwave thermal fusion, a microwave thermal fusion device, and a non-woven fabric preparation device are provided. The flash spinning method includes: step S1, collecting filament bundles to form a non-woven fabric precursor, adding a microwave heating liquid to the non-woven fabric precursor; the microwave heating liquid being configured to absorb microwave energy and convert the microwave energy into thermal energy; and step S2, performing microwave heating on the non-woven fabric precursor containing the microwave heating liquid obtained in the step S1 to obtain a heated non-woven fabric, and performing a hot press forming treatment on the heated non-woven fabric to obtain a finished non-woven fabric. There is no temperature gradient in layers of the non-woven fabric precursor, thereby significantly improving the peeling strength of the finished non-woven fabric.

Antimicrobial and/or anti-odor textile coating composition that reduce and/or prevent bacterial growth and/or control odor(s) on a textile material treated for a prolonged time period including up to, for example, fifty wash cycles. The textile coating compositions may include benzoic acid and at least one of terephthalic acid, and/or a quat silane.

A solid fabric softening composition is disclosed which includes a quaternary ammonium fabric softening compound which is stabilized to form a solid with a mixture of a water soluble organic salt and a medium to long chain carboxylic acid. This stabilizing combination has been shown to effectively form a solid quaternary ammonium based fabric softening composition with up to as much as 70% by weight of quaternary ammonium compound. The formulations are stable at typical storage temperatures of up to 110 F. and provide fabric softening similar to and even superior to other traditional liquid formulations.

The present invention addresses the problem of improving friction characteristics, when wet, of fibers to which a treatment agent for short fibers is adhered, and improving the heat resistance of the treatment agent for short fibers. This treatment agent for short fibers does not substantially include a phosphate compound, but does contain the fatty acid (A) below and a non-ionic surfactant. The fatty acid (A) is at least one fatty acid selected from C1-6 fatty acids, C1-6 hydroxy fatty acids, and salts of the aforementioned fatty acids.

A pile fabric includes ground yarns constituting a ground structure; pile fibers that are tangled with the ground yarns, the pile fibers including portions standing on a front surface side of the ground structure; and an organically-modified silicone-based softener adhered to the pile fibers located on a back surface side of the pile fabric. The pile fibers include at least one selected from the group consisting of acrylic fibers and modacrylic fibers, and have a softening point lower than a softening point of the ground yarns. The portions standing on the front surface side of the ground structure are not fused to each other, and on a back surface side of the ground structure, at least part of the pile fibers located outside of the ground yarns are fused to each other.
