Problems solved by technology

[0004] At present, due to the specific fabric requirements for medical treatment, nursing protection, and surgical operations, it is necessary to match the water-soluble film and the water-soluble non-woven fabric. The common practice is to use glue for bonding. The existence of glue makes it difficult to decompose and cannot meet the needs of the above-mentioned fabrics. There are new methods and equipment for manufacturing the above-mentioned conforming materials

Abstract

The invention discloses a technology for bonding a water-soluble film and a water-soluble nonwoven fabric, and relates to the field of manufacturing of composite film materials. The technology for bonding the water-soluble film and the water-soluble nonwoven fabric includes the following steps: performing wet treatment on at least one surface of the plasma-treated water-soluble film; carrying outwet treatment on at least one surface of the plasma-treated water-soluble nonwoven fabric; and carrying out hot press compounding on the wet-treated surface of the water-soluble film and the wet-treated surface of the water-soluble nonwoven fabric. The technology has the following advantages: 1, the water-soluble film and the water-soluble nonwoven fabric are thermally bonded after subjected to the wet treatment, so connection using glue is avoided, glue-free compounding is completed, and the use requirements of many medical grade materials are met; and 2, the plasma treatment during the wet treatment removes fine dusts and odorous gases in the wet treatment process, so the cleanliness of an obtained composite material is ensured.

Description

technical field [0001] The invention relates to the production field of composite membrane materials, in particular to a bonding process of water-soluble membranes and water-soluble non-woven fabrics. Background technique [0002] Water-soluble film is a new type of environmentally friendly packaging material that can be rapidly degraded by natural factors (H2O) after special processing. It has the effect of improving the land. Therefore, it belongs to a new type of environmentally friendly packaging material. [0003] Water-soluble non-woven fabric refers to a new type of material produced by non-woven fabric technology with water-soluble PVA short fiber as the main raw material. It is a new type of water-soluble functional non-woven fabric. This product and its composite products can be used in embroidery, medical care, nursing protection, surgery, disease prevention and treatment, home textiles, etc. It can be degraded by water after use, and has extremely broad applica...
