Embossed nonwoven fabric

Abstract

The invention discloses an embossed nonwoven fabric which is formed integrally. The embossed nonwoven fabric comprises a nonwoven fabric base layer with embossed patterns and is produced by steps: subjecting a polypropylene raw material and additives to mixed melting and spun-laid process, adopting a hot-pressing embossing roller for one-time hot rolling forming, and spraying glitters to single orboth surfaces of the embossed nonwoven fabric to improve surface quality. By one-time forming of the embossed nonwoven fabric, production efficiency is remarkably improved while outstanding 3D effects are achieved, and high visual and tactile quality of the embossed nonwoven fabric is realized.

Description

technical field

[0001] The invention relates to the field of non-woven fabrics, in particular to a one-time molding embossed non-woven fabric. Background technique

[0002] Non-woven fabrics, also known as non-woven fabrics, are composed of oriented or random fibers, usually using polypropylene as a raw material, which directly uses high polymer chips, short fibers or filaments to pass the fibers through airflow or mechanically, and then It is a non-woven fabric formed by spunlace, needle punching, or hot rolling reinforcement, and finally finished. 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 has a cotton feel. Non-woven fabrics can be made into non-woven bags, and can also be used for decoration and other purposes. When used as decorations, they can be reused. For decorative items, the existing non-woven fabrics are ...

Examples

Embodiment 1

[0031] Mix 100 parts of polypropylene with 5 parts of glass beads with a particle size of 0.2-0.8 mm, and 1 part of nano-SiO 2 After mixing, put it into an extruder, extrude and melt it, spin the molten material, cool and crystallize the spun filaments to obtain a primary monofilament, and draw the primary monofilament to obtain a monofilament , wherein the diameter of the monofilament is 0.08mm, and the specification is 25dtex / 1f-36f. The fiber is laid into a web, and then hot-rolled by a hot embossing roller, and a non-woven fabric with embossing is obtained in one molding, wherein the hot-rolling pressure is 5000KPa, hot rolling temperature is 115°C.

Embodiment 2

[0033] Mix 100 parts of polypropylene with 5 parts of glass beads with a particle size of 0.2-0.8 mm, and 5 parts of nano-SiO 2 After mixing, put it into an extruder, extrude and melt it, spin the molten material, cool and crystallize the spun filaments to obtain a primary monofilament, and draw the primary monofilament to obtain a monofilament , wherein the diameter of the monofilament is 0.08mm, and the specification is 25dtex / 1f-36f. The fiber is laid into a web, and then hot-rolled by a hot embossing roller, and a non-woven fabric with embossing is obtained in one molding, wherein the hot-rolling pressure is 5000KPa, hot rolling temperature is 115°C.
