Abstract: A hot melt adhesive composition is based on an isotactic polypropylene random copolymer (RCP). The composition contains about 4%-50% by weight of the RCP copolymer, about 20%-65% by weight of a compatible tackifier, about 0%-40% by weight of a plasticizer, about 0%-3% by weight of a stabilizer, about 0%-40% by weight of a wax, about 0%-60% by weight of an atactic poly-?-olefin (APAO), and about 0%-40% by weight of a secondary polymer. The adhesive composition may be used in a number of applications such as, for example, in disposable nonwoven hygienic articles, paper converting, flexible packaging, wood working, carton and case sealing, labeling and other assembly applications.

Abstract: The fabrication of multi-layered laminated structures involves a high strength through-bonding technique. In its preferred embodiment, the structure is a nonwoven trilaminate structure which has outer layers of nonwoven material, and an inner elastomeric layer which has a plurality of openings therethrough, (e.g., an elastomeric mesh). During fabrication, beads of through-bonding adhesive (e.g., oil resistant, polybutylene-based hot melt adhesive) is applied to at least one of the nonwoven webs. The inner elastomeric mesh web and the two outer nonwoven webs are then aligned and fed into a compression nip. The compression nip compresses the webs together to obtain intimate contact of the two outer nonwoven webs through the openings in the inner elastomeric mesh web.

Abstract: A polybutylene-based hot melt adhesive composition having a variety of end uses, particularly in construction and elastic attachment applications on nonwoven disposable articles. Unlike typical hot melt adhesives, the present composition can withstand exposure to emollients such as mineral oil and other oil-based ointments without experiencing catastrophic bond failure. The composition includes a polybutylene-based polymer or a mixture of a polybutylene-based polymer and a polyalphaolefin polymer, a tackifier resin, a plasticizer, a wax and a stabilizer. The hot melt adhesive composition can be applied using common application techniques such as extruding or spraying.

Abstract: A method of utilizing microwave energy in the manufacture of disposable nonwoven absorbent articles such as diapers and feminine care products. More specifically, the traditional hot melt adhesives utilized in the production of disposable nonwoven absorbent articles are replaced by adhesives that are microwave sensitive, and which can be activated by microwave energy to provide strong bonds for the finished article.
