A fabric design having the same mesh, count, and weave design can still have very different properties because the fabric is highly depentend on material type. Polyester monofilament is the most widely used type of material in forming fabric design because it offers characteristics that meld with the performance function requirements. Polyester is a stable product resistant to chemicals used in the paper making process. While polyester is the most prevalent material, many other polymers are being utilized and explored. Characteristics can be incorporated into the monofilament to enhance strength, stability, stretch resistance, shower and wear resistance, anti-contamination, softness, shrinkage and color. The following table shows properties and specifications of fabric materials.
