A hook and loop fastener for flat materials and textile products, comprising a hook part and an interlocking part, the interlocking part made of a nonwoven being provided with polymeric threads which define loops of the interlocking part, wherein the threads are textured and are worked into a support made of a nonwoven composite.
A hook and loop fastener for flat materials and textile products, comprising a hook part and an interlocking part, the interlocking part made of a nonwoven being provided with polymeric threads which define loops of the interlocking part, wherein the threads are textured and are worked into a support made of a nonwoven composite;
- wherein the nonwoven composite is made of non-crimped fibers of high stability.
A hook and loop fastener for flat materials and textile products, comprising a hook part and an interlocking part, the interlocking part made of a nonwoven being provided with polymeric threads which define loops of the interlocking part, wherein the threads are textured and are worked into a support made of a nonwoven composite;
- wherein the nonwoven composite is formed from at least two nonwoven layers.
A hook and loop fastener for flat materials and textile products, comprising a hook part and an interlocking part, the interlocking part made a nonwoven being provided with polymeric threads which define loops of the interlocking part, wherein the threads are textured and are worked into a support made of a nonwoven composite;
- wherein the nonwoven composite is made of one of a spunbonded nonwoven/meltblown composition and a spunbonded nonwoven/meltblown/spunbonded nonwoven composition.
A hook and loop fastener for flat materials and textile products, comprising a hook part and an interlocking part, the interlocking part made of a nonwoven being provided with polymeric threads which define loops of the interlocking part, wherein the threads are textured and are worked into a support made of a nonwoven composite;
- wherein the nonwoven composite is formed from at least one upper layer made of nonwoven fabric and one lower layer made of a sheeting;
- and
- wherein the sheeting is bonded by extrusion to the upper layer made of nonwoven fabric.
A hook and loop fastener for flat materials and textile products, comprising a hook part and an interlocking part, the interlocking part made of a nonwoven being provided with polymeric threads which define loops of the interlocking part, wherein the threads are textured and are worked into a support made of a nonwoven composite;
- wherein at least one of the nonwoven fabrics and the textured threads are made of at least one of homo-thread and bicomponent filaments.
A hook and loop fastener for flat materials and textile products, comprising a hook part and an interlocking part, the interlocking part made of a nonwoven being provided with polymeric threads which define loops of the interlocking part, wherein the threads are textured and are worked into a support made of a nonwoven composite;
