Method for heat-setting cross-laminated non-woven fabrics
摘要
In a method of and an apparatus for heat-setting a non-woven fabric in which a warp web and a weft web is cross-laminated, the fabric is gripped at least at its opposite side edges by and between an outer peripheral surface of a hot cylinder and an endless belt normally tensioned against that outer peripheral surface. Widthwise shrinkage is fully prevented during travel of the fabric around the hot cylinder, and firm bonding of the warp and weft webs is attained.
