The invention relates to a process for manufacturing a metallic reinforcing cord (10) for tyres for vehicle wheels. The process comprises providing at least one elongated element (15) comprising at least one metallic wire (11) twisted together with at least one textile yarn (20) and removing said at least one textile yarn (20) from said at least one elongated element (15) to form the aforementioned metallic reinforcing cord (10). Such a metallic reinforcing cord (10) has a helical geometry, consisting only of said at least one metallic wire (11) that extends along a helical path.

The invention also relates to an apparatus (1) for manufacturing the aforementioned metallic reinforcing cord (10).

A contact pressure sensor detects a pressing force applied to a pressed body by a pressing body through a sensor portion disposed between the pressing body and the pressed body, wherein the sensor portion is formed of a knitting yarn including a carbon nanotube yarn, and the sensor portion includes a pressing body contact surface with which the pressing body comes into contact; a pressed body contact surface with which the pressed body comes into contact; knitting yarn intersecting portions formed between the pressing body contact surface and the pressed body contact surface; and void portions formed between the pressing body contact surface and the pressed body contact surface, the void portions being spaces in which the knitting yarn is not disposed.

The invention relates to a metallic reinforcing cord (10) for tyres for vehicle wheels, comprising from two to ten metallic wires (11) twisted together with a twisting pitch (P) and each having a predetermined diameter. In at least some cross sections of the metallic reinforcing cord (10), at least two of said metallic wires (11) are arranged to a minimum mutual distance greater than, or equal to, 2.5 times the predetermined diameter.

Provided is a pile fabric that can provide both a soft touch feel and durability (pile retention and/or suppression of pile loss). The pile fabric is provided with a base structure formed from a warp and weft and a loop pile formed from pile yarn. The pile yarn is twisted yarn with a twist factor of 2.0 or greater. When the pile yarn is untwisted yarn or weakly twisted yarn, insoluble yarn prior to water soluble yarn elimination is twisted yarn with a twist factor of 2.0 or greater. The proportion of pile height to pile yarn diameter is 40 or greater. The gap between adjacent pile yarn strands is 0.5 mm or less. The pile yarn is 50-120 English yarn count. The loop pile has snarling, and the snarling for adjacent piles is entangled.
