Abstract: The present invention relates to an inner shell for toes covering a toe part. The inner shell is weaved by using a plain weaving device to pack a toe part, thereby easily absorbing sweat and being simply worn by the user. Particularly, the inner shell for covering a toe part may be used in the form of surrounding and packing the toe part, rather than surrounding the foot in whole like the existing socks or foot cover types. The inner shell includes a band part for narrowing the width of the foot and preventing the inner shell from being separated from the foot; and an elastic part worn on the foot using elasticity by surrounding the cuneiform end of the foot to prevent the inner shell from sliding and being separated from the sole of the foot. Thus, although the inner shell substantially hangs on the foot, the inner shell is not separated from the foot unless the user tries to take the inner shell off. Also, the inner shell provides excellent feeling of wear as well as being easily worn, has a sweat absorbing function, and is fashionable.

Abstract: The present invention relates to a nonwoven fabric with excellent voluminosity made of hydrophilic filaments, and a manufacturing method thereof. The manufacturing method of a nonwoven fabric with excellent voluminosity made of hydrophilic filaments of the present invention is a manufacturing method of a spun-bond nonwoven fabric by forming a web on a continuous belt by spinning a polypropylene-based polymer, and by bonding through heat-melting. The manufacturing method of a nonwoven fabric of the present invention is characterized by the fact that a first component and a second component polypropylene having mutually different viscosity are induced to each nozzle hole by using a distribution plate having a specific structure and bicomponent-spun to manufacture multi-filaments; the spun multi-filaments are laminated on a continuous porous belt, which is easy to separate a filament web and the belt to form a multi-filament web; and a sheet form, in which an air spray device that facilitates a separation of a filament web and the belt, and the multi-flament web are partially bonded with heat or punched with a needle to be combined and fixated, are wound to manufacture a nonwoven fabric. Wherein the polypropylene is manufactured by adding 0.3-30 parts by weight of cellulose and a hydrophilic polymer selected from polyethylene glycol, polyethylene oxide, polyacrylic acid or polyvinyl acetate based on the weight of the polypropylene nonwoven fabric. The nonwoven fabric with excellent volume made of hydrophilic filaments, and a manufacturing method thereof according to the present invention manufacture a nonwoven fabric by spinning two types of polypropylenes having a mutually different melting index through a multi-stage distribution plate with a specific structure, thereby providing a bicomponent-spinning spun-bond polypropylene nonwoven fabric having remarkably excellent voluminosity while maintaining the excellent spinning workability.
