| The proposed process for bonding together two substrates with an anhydrous or low-water-content partially crystalline adhesive which is solid at room temperature is characterized in that the adhesive is first activated by internal and/or external friction. The substrates are then joined together with the adhesive between them. When allowed to stand, the structure attains its final strength after a period of between a few seconds to a few days. The friction destroys the crystalline structure and causes the adhesive to become gluey, and re-crystallization gives it its final strength and eliminates the gluey quality. The adhesive is based preferably on polyester or polyurethane and used preferably in the form of a gum stick without impermeable packaging. It is especially suitable for bonding paper, since it does not cause corrugation. | ||||||

| The hotmelt adhesive according to the invention containsA) at least one polyurethane prepolymer ofa) at least one polyisocyanate, more particularly toluene diisocyanate and/or MDI,b) at least one polyalkylene glycol in a concentration of more than 10% by weight, based on the hotmelt adhesive as a whole, more particularly polypropylene glycol,c) at least one polyester glycol, preferably at least two polyester glycols with different glass transition temperatures andd) at least one chain extender andB) optionally additives, such ase) a resin, more particularly a hydrocarbon resin, andf) a stabilizer, more particularly toluene sulfonyl isocyanate.The hotmelt adhesive preferably has a melt viscosity of 4 to 100 Pa.cndot.s at 170.degree. C. The PU prepolymer has only one Tg in the DSC curve. The hotmelt adhesive is distinguished by high creep resistance and high early and ultimate strengths. Accordingly, it is mainly used in the shoe industry, more particular, in application machines designed for application in the shoe production line which does not contain any steam-operated preliminary crosslinking stage or a drying tunnel. The hotmelt adhesive is preferably produced by a single-stage process. The adhesive is particularly suitable for fibrous materials, such as leather and textiles. | ||||||

| The present invention relates to polyurethane hot melt adhesives that are hardened by the action of moisture and which contain at least one reaction product from a component that contains NCO groups and an essentially linear hydroxypolyester, hydroxypolyether, and/or hydroxypolyetherester component. In addition, the present invention relates to a procedure for manufacturing a material that is permeable to water only in vapor form, this being in the form of a fiber material, in particular in the form of a web, which is joined to a polyurethane film, in which the fiber material is coated with a polyurethane material and subsequently the polyurethane material is hardened to form a water-vapor permeable film. The present invention also relates to a material that is permeable to water only in vapor form and which is in the form of a fiber material, in particular in the form of a web, that is bonded to a polyurethane film. According to the present invention, a hot melt adhesive with a segmented hydroxypolyester or an hydroxypolyether or an hydroxypolyetherester component is used for this purpose as polyurethane material. The hot melt adhesive according to the present invention can be applied directly or by a transfer technique to the fiber material and is hardened in only one step, by the action of moisture, to form a water-vapor permeable, but otherwise high quality water-proof membrane film. | ||||||
