Far-infrared polyester for textile applications

The goal of the project is to use the ability that certain inorganic materials such as titanium, zinc, zirconium and silicate have to capture and emit far-infrared radiation when incorporated into a cationic polyester fibre in order to be used in medical textiles with health and wellbeing benefits.

The goal of the project is to use the ability that certain inorganic materials such as titanium, zinc, zirconium and silicate in the correct proportions, have to capture and emit far-infrared radiation. When incorporated into a cationic polyester matrix a masterbatch is created which can be used to spin technical yarns for being used in technical textiles. These textiles have the ability to capture IR radiation and transmit it to the wearer, with health and wellbeing benefits. Furthermore, the project will also analyse the effect of the additives in the cationic dye, as well as other possible polyester matrices like PBT, PTT and/or PLA. Hospitals commonly use far infrared in physiotherapy, and various studies have shown that this type of radiation has a vasodilator effect which improves blood flow, blood oxygen levels and the protection of lactic acid. This R&D project aims at incorporating these benefits into innovative added-value medical and sport textiles for being used in high-end medical textiles such as compression articles (knee, wrist and elbow-supports, compression socks, gloves, collars and sheets, blankets and pillows) with uses in the treatment of joint injuries, sprains, chronic aches, fractures and general therapy, and also in technical sports garments which improve performance and recovery of the user. The company SUNGRUP will work in the development of functionalised polyester masterbatches with a variety of mineral concentrations, which must have the ability to capture IR and transmit it to the wearer, as well as being able to be meltspun. ANTEX will subsequently take the masterbatch and spin the yarns, ensuring that their properties of feel, fastness and strength meet the specifications while retaining the functional health properties sought by the project. When the body is exposed to far-IR radiation, endothelial regeneration in blood vessels is improved while increasing the production of nitrous oxide in the endothelium. Nitrous oxide increases dilation in blood vessels, improving blood flow to injured areas being treated with infrared radiation. This fact improves oxygenation and reduces glucose consumption under anaerobic conditions, reducing lactic acid production, improving relaxation and rest and consequently well-being, and reducing recovery times. Increased blood flow and oxygen levels also have an anti-inflammatory and analgesic effect.
