Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabrics, in particular to a laminated printed non-woven fabric. Background Art

[0002] Non-woven fabric is a kind of fabric that does not require spinning and weaving. It is composed of directional or random fibers. It is a new generation of environmentally friendly materials with the characteristics of moisture-proof, breathable, flexible, lightweight, easy to decompose, non-toxic and non-irritating, rich colors, low price, and recyclable. The application field of non-woven fabric is very wide, mainly used in medical protection, clothing, home decoration, industrial fabrics and agricultural fields. The non-woven fabrics in the existing technology are difficult to meet people's growing usage requirements in terms of strength and toughness due to good bonding or entanglement.

[0003] Laminating is a key process in the production of non-woven bags. Plastic is melted using a laminating device and then applied to the surface of the non-woven fabric. This process offers advantages such as high production speed and the ability to meet customization requirements. The resulting non-woven bags are also of higher quality and more aesthetically pleasing. Designing a non-woven fabric that meets both aesthetic needs and functionality for daily use is currently the trend in non-woven fabric design. Summary of the Invention

[0022] (1) The provision of the first toughness-resistant layer and the second toughness layer makes the non-woven fabric have better toughness, thereby enhancing the service life of the non-woven fabric.

[0023] (2) The arrangement of the first hot-melt fiber layer and the second hot-melt fiber layer allows the non-woven fabric to be bonded together by using low-melting-point hot-melt fibers after hot pressing, thereby reducing the use of glue and being more environmentally friendly.
