A carded nonwoven (110) including synthetic staple fibers (120), wherein the synthetic staple fibers have a hydrophilic polypropylene-based composition, said hydrophilic polypropylene-based composition having a polypropylene-based matrix, an ethylene-propylene copolymer additive and a hydrophilic melt additive is disclosed.

An anti-propylene mask and method for preparation thereof is provided; the anti-propylene mask includes a fiber cloth contact layer, an antistatic non-woven fabric layer and a fullerene/nano titanium dioxide spunbond layer which are arranged in sequence; the fullerene/nano titanium dioxide spunbond layer is made by spun-bonding the modified resin material into a fiber web; the raw materials of modified resin materials include matrix resin, carboxylated fullerene derivatives, nano titanium dioxide, a lubricant, and a coupling agent; the modified resin material is prepared by following method: the carboxylated fullerene derivative is mixed and reacted with the nano titanium dioxide to prepare the carboxylated fullerene derivative-modified nano titanium dioxide, which is then blended and extruded with the remaining components in the raw material, and thus prepared. The mask can prevent propylene from entering the human body through the human respiratory organs and has a good anti-propylene effect.

A method for manufacturing a melt-spun nonwoven fabric, in which fibers obtained by melt-spinning a thermoplastic polymer through a spinning nozzle having at least one or more nozzle holes are collected by high-speed air stream according to a spunbond method, includes: the steps of: allowing the melt-spun fibers to pass through local nozzle heaters of a nozzle heating mantle located just on the underside of the spinning nozzle during the spinning; and allowing the melt-spun fibers to be subjected to momentary local heating with a temperature difference of 0.1 to 1,000 C. from a temperature of a pack body. Polypropylene (PP) having a melt flow index (MFI) of 3 to 900 or polyethylene terephthalate (PET) having intrinsic viscosity (I.V.) of 0.5 to 3.0 is subjected to momentary local heating to a high temperature during the spinning to thus perform fiber fineness.

An electrospinning device includes: a plurality of nozzles that discharge a spinning solution containing a resin; and a plurality of power sources for applying charge to the solution. The power sources are connected such that different charges are applied to the solutions discharged from the nozzles, respectively. The fiber sheet is a long fiber nonwoven fabric including first fibers and second fibers that are different from the first fibers. In a histogram based on fiber diameter distributions and frequencies of the numbers of fibers, the fiber sheet has a peak where a ratio P1 of a frequency of the number of fibers of the first fibers to a frequency of the number of fibers of the second fibers is 0.01 or more and 100 or less. Alternatively, the fiber sheet has two or more peaks in the histogram, in which a ratio P2 of a frequency of the number of fibers of the first fibers at a highest peak in a range of a fiber diameter of 3 m or less to a frequency of the number of fibers of the second fibers at a highest peak in a range of a fiber diameter of more than 3 m is 1 or more and 1 000 or less.

Wearable article comprising a laminate with excellent sweat management properties. The laminate comprises a first web and a second web. The second web is formed of a first fibrous layer and a second fibrous layer, which are integrally combined with each other. The second fibrous layer may be more hydrophilic than the first fibrous layer; and/or the second fibrous layer may have higher average surface area per volume than the first fibrous layer.
