Description

technical field

[0001] The present invention relates to nanofiber assemblies. The invention also relates to polymer alloy fibers that are precursors to nanofiber assemblies. The present invention also relates to mixed fibers and fiber structures containing nanofiber aggregates. Moreover, this invention also relates to the manufacturing method of these. Background technique

[0002] Polyester represented by polyethylene terephthalate (hereinafter referred to as PET) and polybutylene terephthalate (hereinafter referred to as PBT), or nylon 6 (hereinafter referred to as N6) and nylon 66 (hereinafter referred to as Polycondensation polymers such as polyamide represented by N66 for short) have been suitable for use as clothing materials and industrial raw materials because of their moderate mechanical properties and heat resistance. On the other hand, addition-polymerized polymers represented by polyethylene (hereinafter referred to as PE) and polypropylene (hereinafter referr...
