7.3 Uses for hook and loop fastener tapes. Type II hook fastener tapes generally have slightly higher shear strength than Type I hook fastener tape when tested with Class 1 loop fastener tapes.

Type III and IV hook fastener tapes are intended to eliminate field fraying, minimize contamination (lint) of hook area, and is generally thinner and more flexible. Type IV offers resistance to autoclaving. Class 1 and 4 hook and Class 1 and 4 loop fastener tapes are intended for general purpose applications. Class 2 hook and Class 2 loop fastener tapes are intended for those applications where flame retardancy is desired. Class 3 and 5 hook and Class 3 and 5 loop fastener tapes are intended for applications where resistance to wetting, high humidity or to UV radiation is required.

7.3.1 Compatibility. The user should determine whether or not the hook or loop fastener tape of one manufacturer should be mated with the hook or loop fastener tape of another manufacturer.

In addition the sewing operation should determine if a selvage tape fastener is compatible with a non-selvage mating tape fastener in a specific application. Due to required color matching of Universal Shade Camouflage based end-items, manufacturers of hook and loop tape cannot be mixed within the same delivery order or lot of a contract.

7.3.2 Special center selvage tape for applications that require extra sewing down the center of the tape. To prevent center stitching problems on the 2-inch tape, the user needs to specify “center selvage tape”. This tape is manufactured with a 1/8 inch to 3/16 inch selvage on each edge and down the center of the tape. This selvage is free of hook and loop.

7.3.3 Sewability. For Type III extruded hook, the stitch line should not be run off any edges.

For all other products to minimize fraying, recommend the stitch line be a minimum of 3/16” from any edge.

7.3.4 Fray Resistance for Universal Camouflage Shades. This requirement provides assurance that any combination of hook and loop tapes, i.e. selvage hook with non selvage loop, non selvage hook with non selvage loop, extruded hook with selvage loop or non selvage loop or options as specified in the contract or purchase order, will not fray up to 25 launderings.

7.4 Special adhesive backing. Special adhesive backings are available which are designed to secure tapes to many diverse materials such as wood, glass, metal, textiles, etc. Other adhesive backings facilitate application techniques (i.e., they may be water activated; heat activated, solvent activated, or pressure sensitive).

7.5 Special marking. A colorless, identification marking of sufficient permanence to withstand a minimum of 3 washings or 3 dry cleanings may be used on the backs of fastener tapes. Infra-red reflective markings are not permissible.

7.6 Slitting. When multiple widths are woven as a single unit, the tapes may be ultrasonically slit to widths leaving selvages as specified, on the edges of each tape.
