Abstract
A process for manufacturing a composite yarn comprising a continuous multifilament core yarn incorporated in a matrix, comprising at least one step of depositing, by coating or extrusion, a matrix comprising a polymer material and a reinforcing filler formed from functionalized particles, onto a core yarn. A composite yarn obtained by such process. A textile comprising at least one such composite yarn.

A process for manufacturing a composite yarn comprising a continuous multifilament core yarn incorporated in a matrix, said process comprising at least one step of depositing, by coating or extrusion, a matrix comprising a polymer material and a reinforcing filler formed from functionalized particles, onto a core yarn, said particles having a functionality added to their surface via at least one organic group to chemically or physicochemically link the reinforcing filler, the core yarn, and the matrix, and providing some of the filler in the inter-filament interstices of the core yarn.
A composite yarn comprising a continuous multifilament core yarn having deposited thereon a matrix comprising at least one polymer material and at least one reinforcing filler, the reinforcing filler being formed from functionalized particles, said particles having a functionality added to their surface via at least one organic group to chemically or physicochemically link the reinforcing filler, the core yarn, and the matrix, wherein the composite yarn has a titer of 135-140 tex.
A composite yarn comprising a continuous multifilament core yarn having deposited thereon a matrix comprising at least one polymer material and at least one reinforcing filler, the reinforcing filler being formed from functionalized particles, said particles having a functionality added to their surface via at least one organic group to chemically or physicochemically link the reinforcing filler, the core yarn, and the matrix, wherein the ratio between the median size (dv50) of the reinforcing particles and the diameter of each of the filaments of the core yarn is in the range from 0.15:1 to 12:1.
