English to French Law/Patents Engineering (general) POLYAMIDE FABRIC ENHANCING BODY WARMING

The invention relates to a process for manufacturing a carbon coffee5 containing polyamide yarn, comprising i) providing a polyamide selected from Nylon6 and Nylon 66; ii) providing a concentrate containing polyamide (PA), coffee carbon (CC) in a concentration of from about 6% to about 10%, and metal oxides (MO) in a concentration of from 3% to 5%.

Knitted cloth samples, including coffee carbon yarn (PA/CC/MO) and reference yarn (PA), either without or with dyeing, were tested for heating properties and for deodorizing properties.

obtaining the coffee carbon-containing polyamide yarn and knitting or weaving a fabric from the coffee carbon-containing yarn.

A yarn for manufacturing a fabric with warm-maintaining and deodorizing properties, the yarn comprising
i) one type of polyamide (PA), said PA being Nylon 66; ii) one type of coffee carbon powder (CC) originating from carbonized coffee husks in an amount of 0.1 to 2.0%.
