摘要:
Curable mechanical fasteners of the invention comprise a fastening surface comprising a curable material, wherein the fastening surface is capable of being repeatedly attached and unattached to a complementary fastening surface, and when attached to the complementary fastening surface and cured, the curable mechanical fastener is capable of becoming permanently attached to the complementary fastening surface. The curable mechanical fastener may also further comprise the complementary fastening surface.

An extruded hook fastener strip is created on a roll having hook forming cavities in its surface by extruding plastic material into the interface between the forming roll and a second strip carried by a backing roll. The second strip is firmly bonded to the fastener strip on that side opposite the formed hooks.

摘要:
Described is a loop pile material composed of a textile backing composed of a knit or woven and bound-in loop-forming pile yarns, whereinthe textile backing consists of a multifilament hybrid yarn composed of at least 2 varieties A and B of filaments with or without cofilaments C, wherein said filaments A are textured,the melting point of said filaments B being at least 20.degree. C., preferably at least 40.degree. C., in particular at least 80.degree. C., below the melting point of filaments A,the weight ratio of the filaments A:B being within the range from 20:80 to 80:20, preferably from 40:60 to 60:40, and the multifilament hybrid yarn additionally containing up to 40% by weight of cofilaments C, and the pile consists of loops with a length of 1 to 4 mm formed from a multifilament yarn having a yarn linear density of 30 to 200 dtex and filament linear densities of 5 to 25 dtex and/or from monofilaments having a linear density of 20 to 70 dtex.The loop pile material is three-dimensionally deformable and heat-stabilizable and is used as the hook surface of hook-and-loop fastenings.

摘要:
A textile fastener consists of monofilaments (12, 14; 22, 28) made of polyesters which have been formed from dicarboxylic acid and diol components and into which a flame retardant has been incorporated.The flame retardant is present in the polyester chains as copolymerized elements having the structural units of the general formula ##STR1## where R is alkylene, arylene or aralkylene and R.sub.1 is alkyl, aryl or aralkyl.
摘要:
In the velvet type fastener, each male element of the male piece consists of a stem and a cap laterally expanded at the top thereof, and is composed of compositions of a first and a second polyamide polymers having different melting points. These polymers are formed in crystalline composition in the stem and in amorphous composition in the cap. The stem consists of a core portion formed with the first polymer of lower melting point, and a sheath portion formed with the second polymer having a higher melting point. The cap consists of a core and outer layer portions formed with the first polymer, and an intermediate portion of a second polymer sandwiched therebetween.

A method for producing a securing object, particularly in the form of a heat-resistant adhesive closure, includes providing metal securing elements (9) having a hooked head (13) and a foot part in the form of a tang (11), providing a support structure (1) having a securing surface (3), introducing perforations (7) into the securing surface (3) for forming seats for receiving the tangs (11) of the securing elements (9), and inserting the tangs (11) of the securing elements (9) into the preformed perforations (7) of the securing surface (3).
摘要:
A hook surface fastener excellent in the heat resistance, flame resistance, retention of hook shape, and pull-out resistance of hook engaging elements (fibers). The hook surface fastener is composed of a base fabric and the hook engaging elements formed on the base fabric. The base fabric is a woven fabric composed of warp yarns, weft yarns and fibers constituting the hook engaging elements. The warp yarns and the fibers constituting the hook engaging elements are polyphenylene sulfide fibers. The weft yarns are substantially non-twisted, paralleled yarns of polyphenylene sulfide fibers and heat-fusible fibers having a melting point or softening point each being 230° C. or lower. The polyphenylene sulfide fibers constituting the hook engaging elements have a crystal orientation of 85.0 to 90.0% and a crystallinity of 32.0 to 42.0% so that the retention of hook shape is good. The fibers constituting the hook engaging elements are anchored to the base fabric by fusion of the heat-fusible fibers. Therefore, the pull-out resistance of the hook engaging elements (fibers) is good even if a resin coat layer is substantially not provided on the back surface of the base fabric. A hook surface fastener substantially free from the resin coat layer has a good heat resistance and flame resistance.
