Abstract
Abstract A sock knitted from a yarn of non-feltable textile fibres, e.g. synthetic fibres. Into the sole, heel and toe regions of the sock is knitted a yarn of feltable textile fibres, preferably wool, forming loop pile meshes therein. After knitting, the sock is subjected to a fulling treatment, whereby the fibres of the yarn knitted into the sole, heel and toe regions of the sock are felted, thus forming soft fibrous layers internally as well as externally in these sock regions. The loop pile meshes and the subsequent fulling treatment thereof make the sole, heel and toe regions of the sock soft and pliable. Because the entire sock is knitted from non-feltable yarns, the sock obtains the desired elasticity and good fit. After fulling the loop pile meshes from a tight structure capable of absorbing and distributing perspiration moisture.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
110 words
An improved sock, particularly intended for sports activities, the improvement comprising the body of said sock being knitted from a yarn of textile fibres that do not lend themselves to felting, a yarn consisting of feltable textile fibres knitted into the fibres of said sock on the opposite side of said sole, heel, and toe regions of said sock, said yarm forming loop pile meshes, and said feltable fibres of said yarn knitted into said sole, heel, and toe regions of said sock being felted and thus form soft layers of fibres on the inside as well as on the outside surfaces of said sock sole, heal and toe regions.
Claim 2
Dependent Claim
110 words
An improved sock, particularly intended for sports activities, the improvement comprising the body of said sock being knitted from a yarn of textile fibres that do not lend themselves to felting, a yarn consisting of feltable textile fibres knitted into the fibres of said sock on the opposite side of said sole, heel, and toe regions of said sock, said yarm forming loop pile meshes, and said feltable fibres of said yarn knitted into said sole, heel, and toe regions of said sock being felted and thus form soft layers of fibres on the inside as well as on the outside surfaces of said sock sole, heal and toe regions.
Claim 3
Dependent Claim
27 words
An improved sock as claimed in claim 1, wherein said feltable yarn knitted into said sole, heel, and toe regions of said sock consist of feltable wool.
Claim 4
Independent Claim
111 words
A method of manufacturing an improved sock, particularly intended for sports activities, comprising the steps of knitting the body of said sock from a yarn of textile fibres that do not lend themselves to felting, knitting into the inner and outer surfaces of the sole, heel, and toe regions of said sock a yarn consisting of textile fibres which can be felted, said feltable yarn forming loop pile meshes, and fulling said sock so as to felt said feltable fibres of said yarn knitted into said sole, heel, and toe regions of said sock, whereby said regions of the sock are imparted a homogeneous, felt-like surface internally as well as externally.
Claim 5
Independent Claim
