    Abstract: Provided are: polyphenylene sulfide fibers which are mainly composed of a PPS resin and has excellent heat resistance and thermal bondability at the same time; and a nonwoven fabric which is configured of the fibers. The polyphenylene sulfide fibers are characterized by being mainly composed of a polyphenylene sulfide and having a sum of the crystallinity and the rigid amorphia of 30-90% (inclusive). The crystallinity is preferably 5% or more but less than 25%. A nonwoven fabric is configured using the polyphenylene sulfide fibers. The nonwoven fabric is preferably integrated by thermal bonding or mechanical interlacing.

    Abstract: Provided is a polyphenylene sulfide composite fiber which consists mainly of a component (A) and a component (B), the component (A) being a resin mainly comprising poylphenylene sulfide that comprises p-phenylene sulfide as the main units and the component (B) being a resin mainly comprising a copolyphenylene sulfide that contains at least one kind of comonomer units besides p-phenylene sulfide, characterized in that at least some of the surface of the fiber is constituted of the component (B). The composite fiber, which is constituted of resins that comprise polyphenylene sulfide as a main component, is heat-bondable and is excellent in terms of heat resistance, flame retardancy, and chemical resistance. Also provided is nonwoven fabric.
