20240150947 · 2024-05-09 ·

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.

Nonwoven composite smokeless tobacco product

A smokeless tobacco product for insertion into the mouth of a user is provided herein. The smokeless tobacco product can be prepared by impregnating a tobacco-containing nonwoven fabric with a second tobacco material, e.g., using at least one alternating electric field. The obtained impregnated tobacco-containing fabric is subsequently bonded to form a composite, which can be further modified in order to obtain desired properties such as moisture content and flavor profile.

Methods for modification of aramid fibers

Methods are described for treatment of aramid fibers to modify the surface of the fibers. The treated fibers have improved adhesion to elastomer materials as compared to untreated fibers. Modification methods include irradiating the fibers, compressing and straining the fibers under a constant pull force and immersing the fibers in a coupling agent fluid. The treated fibers can be used with elastomers and provide reinforcement elements in products such as tires.

SPRAY APPLICATION METHOD FOR TREATING A GARMENT

Methods for treating a garment include: prewashing the garment; drying the garment in a first drying process; spraying a functional chemical onto the dried garment; and applying a curing treatment to the garment to cure the functional chemical. The method may further include drying the garment in a second drying process after spraying the functional chemical onto the garment.
