摘要： A flash spinning method for preparing non-woven fabrics based on microwave thermal fusion, a microwave thermal fusion device, and a non-woven fabric preparation device are provided. The flash spinning method includes: step S1, collecting filament bundles to form a non-woven fabric precursor, adding a microwave heating liquid to the non-woven fabric precursor; the microwave heating liquid being configured to absorb microwave energy and convert the microwave energy into thermal energy; and step S2, performing microwave heating on the non-woven fabric precursor containing the microwave heating liquid obtained in the step S1 to obtain a heated non-woven fabric, and performing a hot press forming treatment on the heated non-woven fabric to obtain a finished non-woven fabric. There is no temperature gradient in layers of the non-woven fabric precursor, thereby significantly improving the peeling strength of the finished non-woven fabric.

摘要： The present disclosure relates to methods for assembling elastomeric laminates, wherein elastic material may be stretched and joined with either or both first and second substrates. First spools are rotated to unwind first elastic strands from a first unwinder in a machine direction. The first elastic strands are positioned between the first substrate and the second substrate to form an elastomeric laminate. Before the first elastic strands are completely unwound from the rotating first spools, second spools are rotated to unwind second elastic strands from a second unwinder. Subsequently, the advancement of the first elastic strands from the first unwinder is discontinued. Thus, the elastomeric laminate assembly process may continue uninterrupted while switching from an initially utilized elastic material drawn from the first spools to a subsequently utilized elastic material drawn from the second spools.
