The invention provides a leakage-proof load-bearing non-
woven fabric hand bag and a manufacturing process, and relates to the technical field of non-
woven fabric hand bag manufacturing. A multi-layer
composite structure design is constructed, and a layered non-
woven fabric hand bag
manufacturing technology based on outer layer protection, middle functions and inner layer
load bearing is provided; on this basis, the process steps of vacuum adsorption
permeation, differential cooling and the like of the high-
porosity PET needle-punched non-woven fabric and the overheat melting PLA material are introduced, and the needle-punched density, the PLA
melting temperature, the vacuum degree, secondary heating and the
cooling rate of the bent position / non-bent position are strictly controlled, so that PLA is fully permeated in PET
fiber pores, and the local rigidity is directionally enhanced; the comprehensive performance of the leakproof load-bearing non-woven fabric hand bag and the manufacturing process hand bag is obviously improved.
