Hot melt adhesives of this invention can comprise a water-soluble polyalkylenimine, an hydroxy substituted organic compound, and optimally a plasticizer, a tackifier, and other ingredients. The adhesives are water actuated, and can be water activated, cleaned by aqueous systems, or recycled in aqueous systems.

Moisture-actuated hot melt adhesive

A means for reclaiming standard carpet by disintegrating and separating carpet into its base component materials, through a process and apparatus that, through a series of mechanical, hydraulic, fluid, heat and pressure devices, separates and segregates carpet into its principal components, i.e., secondary backing, binder, pile and primary backing.

Carpet reclaimer

A fluted filter media to end cap bonding process and fluid filters formed by the bonding process. The process comprises coating at least one end cap and/or at least one fluted edge of the filter media with a bonding composition, contacting the end cap with the edge of the fluted filter media and curing the bonding composition coating to form a strong, continuous filter media to end cap bond. The bonding composition comprises, in adhesive latex, a thermoplastic resin and an amount of ungelatinized granular starch effective to complex a major portion of the latex water during curing of the bonding composition.

Process of bonding fluted filter media to end caps

A basic aqueous emulsion composition that can be used as a treatment for cellulosic sheets or articles made of cellulosic fibers to provide improved water resistance by forming a discrete coating on the individual fibers that make up the sheet while not substantially limiting the compatibility of the treated sheet with aqueous glues, dyes or inks comprising a major proportion of water, a mixture of wax and rosin, an emulsion stabilizer and a chelating agent.

Aqueous emulsion coating for individual fibers of a cellulosic sheet

The present invention relates to an improved book-binding process comprising the use of an aqueous primer adhesive composition containing ungelatinized starch. A layer of the primer adhesive is coalesced to a resilient hinge by the application of a hot-covering adhesive without the need for an intermediate drying step. The coalesced film of primer adhesive provides a suitable underlying substrate for the adherent covering adhesive which binds the cover stock to the finished book.

Book binding process involving primer adhesive containing starch

An aqueous adhesive possessing sufficient adhesion, tack, open time, thermal stability, biological stability, dimensional stability, flexibility and adhesion contains in an aqueous base a polyvinyl alcohol and lignin sulfonate, wherein there are about 1 to 8 parts of the lignin sulfonate per each part of the polyvinyl alcohol.

Bonding method employing an adhesive which contains in an aqueous base

Polyvinyl alcohol and lignin sulfonate containing adhesive

A continuous book binding process and a book comprising a backbone made by the process. The process comprises forming a book block, applying a wet coating of a primer composition to the spine area of the block, thermally drying said coating to remove a substantial amount of water to provide a flexible film having a uniformly irregular surface, and applying a coating of a hotmelt adhesive over the film, wherein the primer composition comprises an adhesive latex and an amount of ungelatinized granular starch effective to complex the latex water so that it is evaporated in a diffuse manner during the drying step. The layer of hot melt adhesive is not disturbed by the evaporation of residual water from the primer film.

Book binding process

A heat-activated pressure-sensitive adhesive which comprises an aqueous emulsion of finely divided solids comprising a rubber polymer, a resin and a plasticizer, which optionally contains urea, a urea-compound and/or a polyhydroxy compound in the aqueous phase. Substrates such as plastic film, metal foil and cigarette paper may be effectively bonded.
