A self-engaging fastener has a flexible base sheet and an array of discrete fastener elements projecting from a broad side of the base sheet. Each fastener element has a stem extending from the base sheet and a head at a distal end of the stem, the head overhanging the base sheet on multiple sides of the stem. The heads of the discrete fastener elements are arranged in a pattern of hexagonal groupings of fastener element heads bordering central regions void of fastener element heads, with each fastener element head spaced from edges of the array being part of three adjacent groupings. The product features a particularly high separation resistance for the area of the product covered by the heads.

A connection system has a first adhesion segment, on which a first connection region is formed, a second adhesion segment, on which a second connection region is formed, and a solidifiable liquid connection substance for connecting the two adhesion segments in a material fit, wherein at least one of the two connection regions is formed flexibly, such that, when the liquid connection substance is introduced between the two connection regions which are opposite one another in an assembly arrangement of the two adhesion segments, a material connection is formed between the two connection regions automatically as a result of the elastocapillary effect via the liquid connection substance.

A fastener member (10) including: a base portion (11) having a surface (15); and a plurality of locking members (12) vertically provided on the surface, the locking members locking with a subject to be coupled so as to mechanically couple to the subject to be coupled; wherein the locking member includes a shaft portion (20), projecting from the base portion, having a pair of side faces (22A, 22B) that are opposite each other in a first direction (x) and, as viewed from the surface, diverge in a second direction (y) orthogonal to the first direction, and a barbed portion (21) provided on each of the pair of side faces; and, as viewed from the surface, the barbed portion provided on at least one of the side faces of the pair of side faces extends in a direction intersecting the first direction and the second direction.

A fabric having a restraining function is fabricated through at least one yarn having thermoplastic fibers, at least one surface of the fabric has hairiness formed with a plurality of thermoplastic hairs, wherein a first restraining hair having a distal end formed with a spherical member and/or a columnar member is formed through at least a part of the thermoplastic hairs, second restraining hair having a distal end formed with an irregular deformed member is formed through at least a part of the first restraining hairs, so that the at least one surface of the fabric is able to provide a restraining function in a horizontal direction and in a vertical direction to a plurality of fibriform loops.

A laser weldable hook-and-loop fastener contains a laser light transmitting male-type molded hook-and-loop fastener (A) and a laser light absorbing layer (B) formed of a thermoplastic resin, which is integrated on the back surface of the male-type molded hook-and-loop fastener (A). The male-type molded hook-and-loop fastener (A) has a base plate and a large number of male-type engaging elements rising from the surface of the base plate. The male-type engaging elements and the base plate are formed of the same resin selected from a polyester elastomer and a polyamide, the male-type engaging elements are arranged in a row, and the laser light absorbing layer (B) has an infrared absorptance of 85% or more at a wavelength of 980 nm.

A self-engaging fastener has a flexible base sheet and an array of discrete fastener elements projecting from a broad side of the base sheet. Each fastener element has a stem extending from the base sheet and a head at a distal end of the stem, the head overhanging the base sheet on multiple sides of the stem. The heads of the discrete fastener elements are arranged in a pattern of hexagonal groupings of fastener element heads bordering central regions void of fastener element heads, with each fastener element head spaced from edges of the array being part of three adjacent groupings. The product features a particularly high separation resistance for the area of the product covered by the heads.
