Benefits of technology
[0018]In the present invention, 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.
[0019]According to the present invention, 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

Abstract
Provided is a nonwoven fabric which is formed from a resin composition and has improved antifouling properties, sound insulation properties, coefficient of friction, and texture. This nonwoven fabric is formed from a resin composition which contains (1) a thermoplastic resin and (2) a fluorine-containing copolymer, and wherein: the thermoplastic resin (1) is a polypropylene; and the fluorine-containing copolymer (2) is a copolymer which has (a) a repeating unit that is formed of a fluorine-containing monomer represented by formula CH2═C(—X)—C(═O)—Y—Z—Rf and (b) a repeating unit that is formed of a non-fluorine monomer having a hydrocarbon group with 14 or more carbon atoms, and which has a weight average molecular weight of 2,500-20,000.
Description
TECHNICAL FIELD[0001]The present invention relates to a nonwoven fabric formed from a resin composition comprising a thermoplastic resin and a fluorine-containing copolymer.BACKGROUND ART[0002]Hitherto, disclosed is a technology of nonwoven fabric which adding a fluorine-containing polymer to a thermoplastic resin.[0003]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.[0004]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 specif...
