摘要： A male touch fastener product has an array of discrete fastening elements extending from a resin base. The elements are formed by molding stems and then deforming at least a rim of a distal end of each head to form an overhanging mushroom-type fastener element. Some are deformed against a hard surface to form flat fastener elements, and others are deformed against a compliant surface and form umbrella-shaped fastener elements. The fastener element heads feature particular structural relationships that enhance their performance, particularly with low-lying fibers.

摘要： A molded hook surface fastener having a base plate and hook engaging elements projecting from a surface of the base plate, both the base plate and the hook engaging elements being formed of a resin mixture containing polybutylene succinate (A), a modified starch having an amylose content of 45% by weight or more (B), and polyvinyl alcohol (C). The resin mixture is further characterized by having both a continuous phase and a dispersed phase, with the polybutylene succinate (A) present in the continuous phase, and the modified starch (B) and polyvinyl alcohol (C) present in the dispersed phase.

摘要： Aspects disclosed herein relate to forming on a substrate fastener elements suitable for use in touch fastener by employing vibration forming methods. The processes described provide for a greater flexibility in manufacturing than prior methods and overcome certain limitations in prior forming techniques. Further, the product made can embody a variety of different configurations suitable for a given application. Employing vibration forming methods, such as ultrasonic forming methods, allows for the use of a wider variety of substrate material than materials used with convention methods of touch fastener formation.

摘要： One aspect of the present invention provides an injection molded mushroom type hook structure. The injection molded mushroom type hook structure of the present invention includes a stem portion and a substantially planar head portion formed at a top end of the stem portion, wherein the head portion includes two protrusion portions extending outwardly at two opposite sides of the head portion in a first direction, at least one extended portions extending outwardly from one side of the head portion in a second direction substantially perpendicular to the protrusions, and four connection portions that are formed at locations where the lateral sides of the two protrusion portions meet adjacent extended portion and the head portion. These structural features allow the injection molded mushroom type hook structure of the present invention to have a substantially same hook-to-loop engagement rate in each direction and an improved hook-to-loop engagement/peeling-off strength. Another aspect of the present invention provides an injection molded hook strap including the hook structure.

摘要： Touch fastener products, as well as apparatus and methods for manufacturing such products, are described. The methods and apparatus feature certain mold cavity shapes that are designed to facilitate demolding of hammer hook touch fastener elements exhibiting desirable fastening properties. Such mold cavity shapes can be combined with particularly soft molding resins to produce useful fastening products.

摘要： A method of forming a continuous sheet of pleated, hook-form, fastener product includes training a substrate about a pressure roll having an outer surface defining circumferential grooves. As the substrate approaches a nip between the pressure roll and a mold roll calendered with the pressure roll, a portion of the substrate is disposed within a corresponding one of the grooves between the pressure roll and a stationary horn extending into the groove whereby a longitudinally-extending pleat is formed in the substrate. The pleated substrate is then passed through the nip where resin regions are laminated to a side of the substrate opposed to the pleat.
