A yarn adaptable to incorporation into a textile comprises a core including one or more electrically conductive traces arranged on the core and distributed over at least a portion of the length of the yarn. The yarn also comprises an electrically contactable terminal arranged at a terminus of the one or more conductive traces and a winding wrapped around the core.

The invention relates to an elastic thread with limited elasticity, comprising: an elastic thread and a shaping layer combined with the elastic thread. The elastic thread itself has stretchable elasticity; the shaping layer is a high polymer material capable of dissolving in water. When the elastic thread is kept in a combined state with the shaping layer, an elasticity of the elastic thread is greatly reduced, and the elastic thread can be made into a textile, or used as an upper thread for sewing threads and embroidery threads, or as an upper thread for jacquard weave. When the shaping layer is dissolved, the elastic thread restores its original elasticity. The textile made with the elastic thread is soft and has stretchable elasticity.

Provided is a method of manufacturing a dental cord. The method including: producing a spinning solution by dissolving a fiber-moldable hydrophobic polymer material in a solvent; spinning the spinning solution to obtain a polymer nanofiber web composed of nanofibers and including three-dimensional micropores; laminating the polymer nanofiber web to obtain a polymer membrane; slitting the polymer membrane to obtain a nanofiber tape yarn; hydrophilic-treating the nanofiber tape yarn to obtain a hydrophilic-treated nanofiber tape yarn; plying and twisting the hydrophilic-treated nanofiber tape yarn with a covered yarn to obtain a nanofiber multiple yarn; and impregnating the nanofiber multiple yarn with a hemostatic agent.

A method of fabricating a multi-level-architecture multi-fiber composite yarn includes infiltrating a composite yarn having a first anisotropic expansion coefficient in an axial and/or radial directions with a matrix material having a second anisotropic expansion coefficient different from the first anisotropic expansion coefficient in the axial or radial direction.

A method of manufacturing comingled yarn of carbon and thermofusible fibres comprises the steps of: feeding a tow of thermofusible fibres from a spool to a blending roller and between the spool and the blending roller, spreading the thermofusible tow; feeding a tow of carbon fibres from a spool to the blending roller; spreading the carbon fibre tow between the spool and the blending roller by applying a flow of air over the tow to urge the tow against a supporting surface over which the carbon fibres pass on their way to the blending roller; combining the thermofusible and carbon fibre tows at the blending roller.

A process for manufacturing air-rich yarn and air-rich fabric is provided. The process of the present invention uses optimized parameters for blending, doubling, drafting and spinning in draw frame, roving frame and ring frame respectively. The process of the present invention provides an air rich yarn comprising a plurality of fibers of a water soluble material interlinked and distributed homogenously across a cross-section of the yarn using the optimized parameters. The plurality of fibers of water soluble material after treatment with water provides an improved air rich yarn comprising a plurality of interlinked through-pores distributed homogenously across the cross-section of the yarn. Further, the present invention provides a process of preparing an air-rich fabric from the air-rich yarn, where the fabric exhibits high wettability, easy dry ability, quick absorbency and increased thickness due to homogenous distribution of the plurality of interlinked through-pores across the cross-section of the yarn.
