The purpose of the instant invention is to provide a superfine carbon fiber thread with excellent bending strength and repeated bending. To achieve this purpose, (1) a desired composite thread is produced by opening open carbon fibers, slitting the opened fibers, twisting the slit fibers and forming a composite with a composite thread; and (2) a composite thread is produced by performing a lamination process with a film (film of composite materials) while performing a fiber-opening process, and then slitting, twisting and heating the tread for stress relief.

A method for improving the translation efficiency of fiber strength into composite strength is provided. A single unidirectional tape, single unidirectional fiber web or a stack of unidirectional web/unidirectional tape plies formed from partially oriented fibers/tapes is primed under mild conditions followed by subjecting the primed plies to an axial extension stress in the axial fiber direction of each fiber ply by passage through a compression apparatus. The axial extension stress extends the fibers, strengthening them, while also compacting the plies together and thereby forming a composite having improved strength. Production yield is improved by avoiding maximal fiber stretching and thereby avoiding typical manufacturing loss, and low weight composite armor having increased strength is achieved.

A knitted textile (2) having a first layer (4) including a first yarn (12) with a thermoplastic composition integrally formed with a second layer (6) including a second yarn (14), the first yarn (12) forming an array of knitted patterns (16) defining voids (8) through the first layer (4) to the second layer (6). The first layer (4) may be heat treated to form a film. (24). Treatment of the first layer (4) may change zonal and directional tensile properties of the knitted textile (2). The Poisson's ratio of the knitted textile (2) may be greater than or equal to zero in a first axis (32) and/or a second axis (30), before and/or after treatment. Articles of apparel, including articles of footwear (26) and garments incorporating the knitted textile (2), and methods of forming the knitted textiles (2) and articles are disclosed.
