The invention provides a method for cutting a composite membrane material, firstly, manufacturing a composite membrane material, the composite membrane material is formed by combining an elastic membrane material with at least one shaping membrane, the elastic membrane material has stretchability and elasticity; the shaping membrane is capable of dissolving in water, and a rigidity thereof is greater than that of the elastic membrane material, and a ductility thereof is lower than that of the elastic membrane material; and cutting the composite membrane material into a plurality of composite filaments with a cutting device, and each of the composite filaments comprises an elastic filament and at least one shaping filament. The composite filament can be used by textile machinery to make textiles. Dissolving the shaping filament in the composite filament is capable of obtaining the elastic filament.

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.

A filament manufacturing device includes an impregnation unit and a twisting unit. The impregnation unit is configured to impregnate a bundle of transported continuous fibers with a resin so as to form a filament. The twisting unit is configured to twist the filament downstream of the impregnation unit in a transport direction in which the bundle of continuous fibers is transported, so as to form the twisted filament.

A composite yarn comprising a continuous multifilament core yarn incorporated in a matrix is characterised in that the matrix comprises at least one polymer material and at least one reinforcing filler, the reinforcing filler being formed from functionalized particles, said particles having a median size (d.sub.v5o) of less than 40 μm. A process for manufacturing such a composite yarn, comprises at least one step of depositing, by coating or extrusion, a matrix comprising a polymer and a reinforcing filler, onto a core yarn. A textile surface comprises at least one such composite yarn.

A multi-level-architecture multi-fiber composite yarn includes a composite yarn having a first anisotropic expansion coefficient in an axial and/or radial direction, and a matrix material included with the yarn, wherein the matrix material has a second anisotropic expansion coefficient that is different from the first anisotropic expansion coefficient in at least one of the axial or radial directions. 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 textile component includes a yarn which includes a thermoplastic material. A blowing agent with at least activation condition is included into the textile, either by inclusion in the yarn or impregnating in the textile after forming an un-foamed textile. Upon triggering the activation condition of the blowing agent, the blowing agent introduces a plurality of cavities, i.e. cells, into the thermoplastic material. The textile then comprises a multicellular foam area of the textile wherein the multicellular foamed area comprises a multicellular foam surrounding a core yarn. The textile, in either its un-foamed or foamed condition, can be incorporated into a variety of articles, such as an article of footwear.

The yarn includes a thermoplastic material and a blowing agent with an activation condition. Upon triggering the activation condition of the blowing agent, the blowing agent introduces a plurality of cavities, i.e. cells, into the thermoplastic material, creating a multicellular foam area of the textile.

A knitted component may include a first area, where the first area includes a plurality of knit loops comprising a first yarn. The knitted component may also include a second yarn at least partially inlaid within the first area of the knitted component such that the second yarn extends between at least a first loop and a second loop of the plurality of knit loops. The second yarn may have a foamable material comprising a blowing agent and a thermoplastic polymer.

The present invention provides a knitted fabric with leather fibers comprising a ground yarn layer and a face yarn layer directly connected with the ground yarn layer through double knitting. The ground yarn layer includes a plurality of first yarn loops, each of the first yarn loops is formed by a plurality of ground yarns. The face yarn layer includes a plurality of second yarn loops, each of the second yarn loops is formed by at least one face yarn attached with the leather fibers obtained from a piece of leather by a pulverization operation.
