The present invention relates to a composite fiber for obtaining a fiber having a strength at 100% elongation of 0.04 cN/dtex or less,

Composite fiber

A modified ethylene-vinyl alcohol copolymer fiber includes an ethylene-vinyl alcohol copolymer containing 0.1 to 10 mol % of a modified component and 5 to 55 mol % of ethylene, and has a crystallinity of 25% to 50%.

Modified ethylene-vinyl alcohol copolymer fibers

Provided is a flame-retardant fiber having improved light resistance and/or colorability. The flame-retardant fiber is a fiber including a fiber-forming polymer. The fiber-forming polymer contains a polymer blend comprising a polyetherimide polymer (A) and a thermoplastic polymer (B) having a glass transition temperature lower than that of the polymer (A); and the fiber-forming polymer further contains a functional additive (C) that provides light resistance, colorability, or both of light resistance and colorability. The mass ratio (A)/(B) of the polymer (A) to the polymer (B) is from 50/50 to 90/10, and the content of the functional additive (C) is from 0.5 to 10% by mass relative to 100% by mass of the total mass (A+B+C) of the polymer (A), the thermoplastic polymer (B), and the functional additive (C).

Flame-retardant fiber, method for producing same, fabric using flame-retardant fiber, and resin composite material using flame-retardant fiber

A target capsule includes (A) a pedestal having a central projection, (B) a pedestal aid attached to the central projection so as to define a sample-loading assembly, and (C) an impact-receiving member, wherein the components (A), (B), and (C) are detachable from each other. The impact target capsule can be readily loaded with a sample, allows the sample to be easily retrieved after application of impact pressure, and can be used repeatedly, and thereby the capsule can be preferably used as an impact compression apparatus in combination with a single-stage powder gun or a single-stage gas gun.
