What are “Sew Quality” and “Pressure Sensitive Adhesive” hook & loop?
Sew quality refers to hook & loop that does not have an adhesive backing; it is intended for applications that involve sewing the hook & loop to another material. Pressure-Sensitive Adhesive (PSA) is an adhesive that comes pre-coated on the back of hook & loop material. PSAs are considered a semi-permanent bond; they are not washable or dry-cleanable.
