Thermocalendered non-woven elastic laminate |
摘要 |
An elastic laminate fabric useful for applications including apparel, sanitary products, and the like has an elastic vinylidene isoprene polymer film sandwiched between two outer non-woven layers. The laminate elastic fabric has CD elongation of at least 120%, and has recovery of at least 85% after several cycles of 100% elongation. A method of making the non-woven elastic laminate fabric includes extrusion coating a non-woven web having CD elongation of at least 120% with a vinylidene isoprene polymer film, and then thermocalendaring a second non-woven layer having a CD elongation of at least 120% to the exposed film surface. The mode of thermocalendering includes the use of an engraved calender roll having a discontinuous roll pattern and a land area no greater than 15%.
