Abstract

The invention provides a preparation method of tough non-woven fabric for packaging. The preparation method of the tough non-woven fabric for packaging comprises the following steps: S1, preparing soaking liquid; S2, performing big-screw high-temperature melt extrusion on a mixture of a fine fiber polymer and binder fiber under the heating temperature of 260 to 280 DEG C to obtain a polymer B in amolten state, performing pressurizing and spinning jet on the polymer B through an extruding machine under 4.8 to 5.3 MPa, stretching the jet yarn by a stretcher to form a fiber drawing object C, guiding into a solution A, soaking for 4 to 8 hours and guiding on a lapper; and S3, when three layers or four layers of fiber drawing objects C are stacked on the lapper, guiding the stacked object to irradiate by an ultraviolet irradiating area for 15 minutes, guiding into a hot rolling mill to perform hot rolling to obtain non-woven fabric and winding and forming, wherein during hot rolling, resinpowder is sprayed on the surface of the fiber drawing object uniformly and the hot rolling conditions are 160 to 180 DEG C and 4 MPa. Good bearing effect, high toughness and bactericidal ability areachieved.

Description

technical field [0001] The invention relates to the field of non-woven fabric preparation, in particular to a method for preparing a strong non-woven fabric for packaging. Background technique [0002] Non-woven fabric is a kind of non-woven fabric, which directly uses polymer chips, short fibers or filaments to form fibers through airflow or machinery, and then undergoes hydroentanglement, needle punching, or hot rolling reinforcement, and finally finishes finishing Formed non-woven fabric. A new type of fiber product with soft, breathable and planar structure. The advantage is that it does not produce lint, is strong, durable, and silky soft. It is also a kind of reinforcing material, and it also has a cotton feel. Compared with cotton fabrics, non-woven fabrics Cloth bags are easy to form and inexpensive to make. [0003] Non-woven fabrics are widely used in the packaging field, but the current non-woven fabric packaging is not very strong and has limited load-bearing c...
