PROBLEM TO BE SOLVED: To provide a reactive hot-melt adhesive that maintains the length of the duration of time during which its adhesion force can be effective after the adhesive is applied, improves adhesion to a substrate having a low polarity, further improves dry cleaning resistance and washing resistance by increasing the crosslinking density after curing and can be used for the application to fiber materials. SOLUTION: The reactive hot-melt adhesive comprises (A) a polyisocyanate and (B) a polyol wherein the polyol (B) comprises (C) a polyolefin polyol, (D) a xylene resin, (E) rosins, (F) a polyester polyol and (G) a polyether polyol as the essential components.
