Problems solved by technology

Since the nonwoven is used as the textile base structure, the entire composite element has a soft, pleasant handfeel, but in this case, due to the use of the nonwoven, a relatively high weight per unit area and thus high production costs

Embodiment Construction

[0040] figure 1 A known composite material element for a Velcro fastener, in particular for a diaper fastener, is shown which has a carrier 1 in the form of a film and a textile material 2 bonded to the carrier 1 . The textile material 2 is a knitted fabric having a thread F made of a first base yarn 1 and the thread F of the second base yarn 2 Woven base structure.

[0041] In addition, loop threads S are incorporated into the base structure by weaving, said loop threads forming loops for connection with Velcro hooks.

[0042] The carrier 1 and the textile material 2 are joined by an adhesive, not shown, which is arranged in a pattern with adhesive surfaces and adhesive-free regions. For example by EP 2 439 323 A1 figure 2 a The known "dog-bone" structure with intersecting, wavy bonding lines is suitable, wherein the surface coverage of the bonding surface is preferably about 20% and the average coating weight over the entire surface is 2g / m 2 . For example, one-compo...

Abstract

The invention relates to a composite material element for a nylon hook-and-loop fastener, particular for a diaper hook-and-loop fastener. The composite material element is provided with a carrier (1) and a textile material (2) adhering to the carrier; the textile material is provided with a base structure formed by threads or fibers and looped threads (S) which are combined into the base structure through weaving, and the looped threads form a loop used for being connected with hooks of the nylon hook-and-loop fastener. The looped threads (S) are formed through polyfilament yarn subjected to treatment of the deformation process on the basis of polyester or polyamide.

Description

technical field [0001] The invention relates to a composite material element for a Velcro fastener, in particular for a diaper fastener, having a carrier and a textile material bonded to the carrier, the textile material having a basic structure woven from threads and loop threads incorporated into the base structure by weaving, said loop threads constituting the loops for connection with the Velcro claws. Furthermore, the invention relates to a method for forming a composite material element of a hook and loop fastener. Background technique [0002] Velcro includes a loop portion and a claw portion according to its usual construction scheme. The corresponding Velcro fasteners are also known as hook and loop systems. Velcro is not only used for multiple uses, but also for single-use items such as diapers, especially baby diapers or incontinence products for adults. [0003] In diaper fasteners for disposable diapers, composite element materials are generally used, which c...
