Making soft fabric touch fasteners

Methods of making a male touch fastener product, by shearing distal portions of loops extending from a side of a flexible fabric, leaving fibers extending from the side of the flexible fabric in place of the sheared loops, the fibers extending to respective free distal ends, while leaving other loops extending from the side of the fabric intact, and then heating the distal ends with energy supplied by a linear energy source, such that resin of the distal ends flows to form enlarged heads on the extending fibers, while leaving at least some of the other loops intact. A male touch fastener product has fibers that form both loops and fiber segments extending from the base to respective distal fiber ends spaced from the base. Each distal fiber end forms an enlarged head of fiber resin for snagging other fibers.

A male touch fastener product has a flexible fabric base with a broad side, and fibers extending from the broad side of the base. The fibers form both loops of fibers, each loop extending from the base at two spaced-apart points, and fiber segments extending from the base to respective distal fiber ends spaced from the base. Each distal fiber end forms an enlarged head of fiber resin for snagging other fibers.

ARTICLE

Article includes: male and female fastening parts secured onto separate locations on the article, the male and female fastening parts being mutually engageable; and at least one article component having a nappable region with which the male fastening part is brought into contact at least partially. The male fastening part includes a multiplicity of male engagement elements where male engagement elements are two-dimensionally arranged, the multiplicity of male engagement elements including two or more male engagement elements each having a top surface that is brought into contact with the nappable region. The respective ones of the male engagement elements of the multiplicity of male engagement elements or of the two or more male engagement elements are made of a same polymer material having a bend elastic constant of 800 MPa or less, or 500 MPa or less, or 450 MPa or less.

To provide a connecting sheet with appropriate softness as well as a garment adhering article that can be attached to clothing. A connecting sheet connects with a target object by being superimposed on the target object, which includes: a sheet base material having a first main surface and a second main surface; a plurality of hook members protruding from the first main surface of the sheet base material in a first direction arranged mutually separated in a second direction in which the first main surface extends; and an adhesive layer adhered to the hook members, wherein the polyethylene content of the sheet base material and hook member is 15 weight percent or more, and the density of the polymer or polymer mixture of the sheet base material and the hook member is 0.925 g/cm.sup.3 or less.
