Abstract: A method of making a loop fastener product features knitting, such as by circular knitting, a pile yarn and one or more ground yarns to form a stretchable knit fabric having loops of the pile yarn extending from a knit ground, with the ground yarns including polymers of differing melt temperatures. The knit fabric is then held in a desired state while the fabric is set by first applying sufficient heat to cause the lower melt temperature resin to flow into interstices of the fabric ground, and then allowing the fabric to cool. The cooled fabric ground is less stretchable in two orthogonal directions after setting than before setting, has a greater air permeability after setting than before setting, and has hook-engageable pile loops extending from bound interstices.
