    摘要: A surface fastener includes a base portion and a plurality of engaging elements, the base portion and the engaging elements include a thermoplastic resin at least partially including a plant-derived resin, the plant-derived resin has an MFR of 5 g/10 min or more and 30 g/10 min or less, and has a flexural modulus of 800 MPa or more and 2300 MPa or less, and, in plan view of each of the engaging elements, the engaging head portion is such that at least a part of the engaging head portion has a shape protruding outward with respect to an upper end of the stem portion. Therefore, the surface fastener can include a plurality of engaging elements. In addition, compared to the related art, it is possible to reduce the use of fossil-resource-derived resin to thereby reduce the load on the environment.

    摘要: A connection system consists at least of an adhesion part and a fastening part. The adhesion part has at least one support part having a plurality of stem-like adhesion elements integrally joined thereto, the head parts of which adhesion elements can be releasably fixed at their free end faces to third components by means of adhesion. The fastening part is rigidly connected to the adhesion part on one side, and on another, opposite side has exposed fastening elements which, when brought into engagement with additional, correspondingly designed fastening elements of an additional fastening part, form a releasable adhesive fastener.

    摘要: The invention relates to a method for forming a fastener having fastener members (23, 63) wherein molten polymer material is deposited by a deposition device onto a contact release surface (7, 27, 32), thereby forming preform projections (20, 60), which contact the front surface (21) of a carrier (13, 62) with their terminal ends (22, 61) and bond to the carrier (13, 62). The carrier (13, 62) is removed with the preform projections (20, 60) attached, thereby separating the preform projections (20, 60) from the contact release surface (7, 27, 32) and forming fastening members (23, 63) projecting from the front surface (21) of the carrier (13, 62). The invention relates further to a method for manufacturing a precursor web (66) for manufacturing a fastener, a fastener web (91, 94,101) for engaging with a loop fabric and a precursor web (66) for manufacturing a fastener.
