The present disclosure provides composite yarn, apparatus and methods preparing thereof. The composite yarn of the present disclosure includes wrapping fibers and a central yarn that is formed by a first body yarn and a second body yarn, wherein a portion of the wrapping fibers are combined with the central yarn in at least one of the following states: a first state, a portion of the wrapping fibers wrap around the first body yarn or the second body yarn; a second state, a portion of the wrapping fibers wrap around the first body yarn and the second body yarn respectively at the same time; a third state, a portion of the wrapping fibers wrap around the central yarn. The composite yarn of the present disclosure has low twist factor and high strength, which solves the problem of severe strength loss associated with low twist factors existing in conventional low-twist techniques.

Provided are: a cloth including thermoplastic synthetic staple fibers, especially a woven or knitted fabric in which occurrence of pilling is suppressed and a reduction of the strength or deterioration of the texture of the cloth is suppressed; and a method for manufacturing the cloth. An anti-pilling cloth including thermoplastic synthetic staple fibers, wherein the anti-pilling cloth is characterized by having, on the surface of at least one side of the cloth, melt balls at ends of the staple fibers and polishing traces of melt balls at fluff tip ends of the staple fibers; and a method for manufacturing the anti-pilling cloth.

An implantable, pliable silk device (e.g., in a form of a knitted mesh) for use in human soft tissue support and/or repair that provides stretch or pliable properties, e.g., multi-directional elongation properties. Such a device permits physicians or users to alter or manipulate the device dimension and/or shape at the time of device implantation, thereby permitting the device to conform to the contour of a target area or tissue more easily and providing more precise positioning of the device over the target area or tissue. In some embodiments, the implantable pliable silk device comprises a knit pattern feature that substantially prevents unraveling and preserves the stability of the mesh when cut. For example, the pliable silk device is a knitted mesh comprising at least two yarns laid in a knit direction and engaging each other to define a plurality of nodes.

Provided are continuous filament-based elongate bodies having improved durability and bending fatigue performance. The elongate bodies are formed from a plurality of fibers where at least one component fiber is a multifilament ultra-high molecular weight polyolefin fiber having a filament intrinsic viscosity (IV.sub.f) of from 15 dl/g to about 45 dl/g when measured in decalin at 135 C., wherein said at least one multifilament ultra-high molecular weight polyolefin fiber has a tenacity of at least 32 g/denier, a denier of greater than 800, and a denier per filament of greater than 2.0. The high tenacity combined with high fiber denier and high filament denier (dpf) enhances the cyclic bend over sheave (CBOS) durability when the elongate body is incorporated in a multi-fiber construction such as a rope.
