METHOD AND SYSTEM FOR IMPROVING CREEP PERFORMANCE IN ELASTIC APPLICATIONS
20170361597 · 2017-12-21 ·

A method and system of using a polyolefin-based, hot melt adhesive improves creep performance of elastic strands adhered to another substrate. Some deflection, greater than 1°, of the exit angle formed by a line normal to the axis of a neutrally-positioned applicator and the elastic strand extending from the applicator is introduced. Preferably, deflection of the entrance angle is also introduced and a head tilt angle is also provided. The use of deflection improves creep performance or allows for a reduced amount of adhesive to be used to achieve the same or similar creep performance. The elastic strands may be used to form a leg cuff in personal care products, such as diapers, and the substrate to which they are applied could be a polyethylene film or non-woven materials.
