Problems solved by technology

Due to the poor mechanical properties of the nanofiber membrane, it must be combined with the base fabric to have practical application value in the field of clothing. However, when the nanofiber and the base fabric are combined, it is not easy to completely bond between the two, and it is easy to separate during use. and other defects, so there are few studies on composite fabrics such as nanofiber membranes and woven fabrics and nonwoven fabrics.
On the other hand, since most electrospinning solutions use volatile chemical reagents as solvents, there are environmental pollution problems during the spinning process.

Description

technical field [0001] The invention relates to a nanofiber composite fabric and a preparation method thereof, in particular to a water-soluble PVA nanofiber composite fabric and a preparation method thereof. Background technique [0002] Due to the high specific surface area of ​​nanofibers, good adsorption performance, and excellent properties such as the small pore size of nanofiber membranes, electrospun nanofibers have attracted attention in the field of protective fabrics. Their protective properties mainly include: filtration, antibacterial, water-proof and breathable, and thermal protection. , Chemical protection, UV protection, etc. [0003] At present, there are relatively many studies on the self-protective properties of nanofiber membranes, and they mainly focus on filtration and antibacterial aspects. Due to the poor mechanical properties of the nanofiber film, it must be combined with the base fabric to have practical application value in the field of clothing...
