Impregnated Yarn & Fabric

3M™ Dyneon™ PTFE and FTP Dispersions show excellent wetting performance for impregnation of fabrics, felts and other textiles used in industrial processes and consumer products. Impregnation of a yarn or fibre leads to optimal distribution of the fluoropolymer in the woven material and therefore ideal protection of the fabric.

An important difference between a fluoropolymer impregnation and a coating is that impregnations do not require a sintering step in the process while still providing the carrier materials with well known fluoropolymer characteristics like broad chemical and temperature resistance, dirt repellency and reduced friction. Impregnation is therefore recommended where sintering is not possible, i.e. where the carrier material would not withstand high sintering temperatures.

Impregnated Non-Woven Fabric

A popular application of fluoropolymer impregnated non-woven fabrics like fleece or felt materials are i.e. filtration systems in various industries. These kinds of materials are often impregnated with fluoropolymers to create non-stick / sliding properties or enhance chemical or temperature resistance.

Impregnated Woven Fabric

One purpose of impregnating woven fabrics with fluoropolymers is to create a cloth which is very easy to clean and has good non-stick properties. Filter bags are one example of application for these impregnated fabrics.

Impregnated PTFE Yarn

Fluoropolymer impregnated PTFE yarn can be found e.g. as dental floss - the good sliding properties of fluoropolymers being the primary factor for use in this application. It can also be found in woven fabrics or other textiles which are used in architectural or even clothing applications, where durability, dirt repellency and flexibility are important.

Impregnated Glass Yarn

Impregnating glass yarn prior to weaving ensures an evenly distributed fluoropolymer impregnation of the finished glass cloth, surrounding and protecting the yarn itself rather than only the fabric surface.
A commonly known application of glass cloth made from fluoropolymer impregnated glass yarn are filtration bags in industrial applications with chemically aggressive surroundings or in high temperatures.

Impregnated Aramid Yarn

Woven aramid yarn in form of a fabric is characterised by its high resistance to impact and abrasion damage, which makes it perfect for aggressive industrial environments.
Heightened chemical and temperature resistance as well as enhanced sliding properties - which can be achieved by impregnating the aramid yarn with fluoropolymers prior to weaving - are highly appreciated in e.g. conveyor belts or other belting applications.
