The application discloses a tape for stitchless joining of fabric sections. In some embodiments the tape is heat activated and includes a thermostable liner and a layer of dry latex of polyurethane with a crosslinker. Methods of manufacturing and using the tape are also disclosed.
Microplastic Removal Using Adhesives
Articles comprising pressure-sensitive adhesives and methods of their use for removing micro- and nanoplastic particles from various media, including wastewater effluent, laundry effluent, and indoor air, are disclosed.
ENVIRONMENTALLY CONSCIOUS HOT MELT ADHESIVE COMPOSITIONS INCLUDING ALIPHATIC PLASTICIZERS
The inventors have discovered hot melt adhesive compositions that can be formulated to have a high percentage of environmentally conscious components and still provide performance over a broad temperature range.
The invention features a hot melt adhesive composition including from 5% by weight to 50% by weight of a styrene block copolymer, from 15% by weight to 75% by weight of a bio-based tackifying agent, and from 5% by weight to 40% by weight of an aliphatic plasticizer having a cyclo-aliphatic content of no greater than 1% by weight as tested by .sup.1H-NMR Spectroscopy, wherein said hot melt adhesive composition has an environmentally conscious component content of at least 50% by weight.
HOT MELT TAPE FOR VELCRO WITHOUT SEWING AND METHOD FOR MANUFACTURING SEAT PADDING MATERIAL FOR VEHICLES USING THE SAME
Disclosed are a hot melt tape for hook-and-loop fasteners without sewing which may be adhered at a low temperature and complete hardening of an adhesive resin in a short time and a method for manufacturing a seat padding material for vehicles using the same. The method includes preparing the padding material and a hook-and-loop fabric, preparing a hot melt tape having a hot melt resin layer by coating a surface of a release paper with a reactive hot melt resin having a melting point of 40-80° C. before reacting, adhering the hot melt tape to a surface of the padding material by applying heat of a temperature of 30-70° C. and pressure thereto, removing the release paper, adhering the hook-and-loop fabric to the exposed hot melt resin layer, and hardening the hot melt resin layer by cooling the padding material and the hook-and-loop fabric to a temperature of 0-20° C.
Methods of disassembling apparel products having shape memory adhesives
Embodiments provide methods of disassembling an apparel product. The methods include exposing an adhesive of the apparel product to heat or electromagnetic energy. The adhesive is disposed at least partially disposed between a major component and a minor component of the apparel product. The adhesive includes a shape memory material. The major component forms a base portion of the apparel product and is configured to be supported and worn at least partially over a portion of a wearer. The minor component forms a secondary portion configured to be coupled to the major component with the adhesive. The methods include separating the major component from the minor component adjoined by the adhesive.
