Definitions
- the present invention relates to a nonwoven fabric formed from a resin composition comprising a thermoplastic resin and a fluorine-containing copolymer.
- thermoplastic resin Hitherto, disclosed is a technology of nonwoven fabric which adding a fluorine-containing polymer to a thermoplastic resin.
- WO 01/053585A discloses a nonwoven fabric prepared by adding a lubricant comprising a vinylidene fluoride/hexafluoropropylene copolymer as processing aid to polypropylene. However, there is no surface modification effect in this nonwoven fabric comprising the fluorine-containing copolymer.
- JP H09-511700A discloses a method of increasing a head-of-water pressure and an intensity to a nonwoven fabric having an average fiber diameter of at least 10 micrometers comprising a specific fluorocarbon.
- JP 2002-521586A discloses a method of giving water repellency and alcohol repellency to a nonwoven fabric surface by adding a fluorine-containing additive agent to a specific region. These methods have a surface modification effect, but other effects cannot be seen.
- JP 2006-37085A discloses a method of mixing a fluorine-containing copolymer with a thermoplastic resin to performing a surface modification.
- a fluorine-containing copolymer with a thermoplastic resin to performing a surface modification.
- water- and oil-repellency specialized in alcohol repellency is indicated as an effect, but other effects cannot be seen.
- An object of the present invention is to provide a nonwoven fabric formed from a resin composition having improved antifouling property, sound insulation property, friction coefficient and touch feeling property.
- the present invention relates to a nonwoven fabric formed from a resin composition comprising (1) a thermoplastic resin, and (2) a fluorine-containing copolymer.
- the present invention provides a nonwoven fabric which is a meltblown nonwoven fabric, comprising fibers which are spun from a resin composition, the resin composition comprising:
- the present invention provides a method of producing a nonwoven fabric, comprising steps of:
- the resin composition (or the antifouling resin composition) can be processed into a nonwoven fabric with high processing characteristics.
- a melt flow rate (MFR) of the resin composition is improved. Further, processing stability at the time of preparation of the nonwoven fabric is high, and the productivity of the nonwoven fabric is high.
- a surface-modified nonwoven fabric is obtained.
- the nonwoven fabric of the present invention has excellent antifouling properties, sound insulation properties, and water-proof pressure. Furthermore, the nonwoven fabric of the present invention has excellent wiping easiness and scratch resistance. In addition, the nonwoven fabric has a good touch feeling due to a decrease in a coefficient of friction.
- a nonwoven fabric having a small fiber diameter and a high density can be obtained.
- the thermoplastic resin is polypropylene.
- polypropylene examples include isotactic polypropylene, syndiotactic polypropylene, atactic polypropylene, and amorphous polypropylene.
- the isotactic polypropylene is a highly crystalline polypropylene based on isotactic polypropylene prepared by a Ziegler-Natta catalyst or a metallocene catalyst.
- the amorphous polypropylene is, for example, propylene having extremely low crystallinity prepared by using a metallocene catalyst.
- the amorphous polypropylene may be a mixture of polypropylene having extremely low crystallinity (for example, at least 50 wt% of a total amount of the mixture) produced by using a metallocene catalyst, with other propylene.
- the amorphous polypropylene is available as, for example, TAFTHREN T-3512 and T-3522 manufactured by Sumitomo Chemical Co., Ltd., and L-MODU S-400, S-600 and S-901 manufactured by Idemitsu Kosan Co., Ltd.
- thermoplastic resin may be one or a combination of at least two.

- the fiber diameter can be thin by increasing the MFR of polypropylene used as a base, and also by decreasing the nozzle caliber. It is shown that the fiber diameter is thinner by adding the fluorine-containing copolymer according to the present invention.
- the nonwoven fabric of the present invention can be used as, for example, a clothes and sanitary material (for example, operation clothes, a paper diaper, a sanitary napkin), a filter (for example, a battery filter, a filter of a dust-proof mask, a filter of an air-conditioner or an air purifier), a separator for batteries, a packaging material, a nonwoven fabric wiper, an automotive interior material or exterior material (for example, a door trim, an instrument panel, a tire house, a bumper, a floor cover, a bonnet cover, a roof cover), and a building material.
- the nonwoven fabric of the present invention is suitable for a medical use.
- the nonwoven fabric can be used for a surgical gown, an operation drape, a sheet, a bandage, a wiping cloth, a pillow cover, a mask and a covering cloth.
