Description

Polymeric yarns, compositions and methods

Technical Field

The present disclosure relates to the textile industry, and more particularly, to polymeric yarns and compositions having antimicrobial and/or antibacterial properties.

Background

The textile industry has traditionally used natural and synthetic fibers to make various products. Each of which has advantages and disadvantages related to strength, comfort, flexibility, longevity, and the like. In addition to providing traditional performance, there is an increasing demand for higher quality fibers, and manufacturers have begun to incorporate more functional elements into the fibers to provide better comfort, freshness and hygiene to the user. To meet the needs of modern sanitary lifestyles, various attempts have been made to add various chemical agents to fabrics to impart antimicrobial and antibacterial properties. These agents are typically applied to the surface to impart antimicrobial and antibacterial properties to the fabric during the finishing stage.

However, articles made with such fabrics do not retain antimicrobial and antibacterial properties for long periods of time and the compounds are washed away during laundering or uv exposure. An important reason why these fibers do not provide long-term antimicrobial and antibacterial action is that these ingredients are added to the fibers during the fabric finishing stage by using various finishing agents. In addition, there is always concern about the use of such chemical agents and their potential sequelae to the human body.

Therefore, innovations in this technology are needed to overcome the ubiquitous drawbacks in the market.

The temperature of this fluid must be such that the yarn does not melt. If the temperature of the yarn is above the melting point of the yarn, the residence time of the yarn in the heat-setting device must be reduced.
