Embodiment 1

[0026] External non-woven fabric, including the following percentages by mass: high-fat polypropylene 70%, low-fat polypropylene 10%, emulsifier 0.6%, wetting agent 0.3%, wetting agent 0.3%, spreading agent 0.3%, antistatic agent 1%, graphene 0.4%, color masterbatch 1%, and the balance is distilled water.

[0027] In this embodiment, first, high-fat polypropylene, low-fat polypropylene and color masterbatch are hot-melt mixed, and then emulsifier, wetting agent, wetting agent, spreading agent, antistatic agent and graphene are added to the mixed melt Liquid, the main component of the external non-woven fabric is high-fat polypropylene, which is used to ensure the elasticity and waterproof ability of the composite non-woven fabric. By adding a certain proportion of graphene, the waterproof performance of the non-woven fabric is effectively improved, and then melted The liquid is sprayed onto the roller for hot-melt molding. The hot-melt formed non-woven fabric has a large area ...

Embodiment 2

[0029] The middle non-woven fabric, including the following percentages by mass: high-fat polypropylene 30%, low-fat polypropylene 50%, emulsifier 0.6%, wetting agent 0.3%, wetting agent 0.3%, spreading agent 0.3%, antistatic Agent 1%, polyether silicone oil 0.2%, color masterbatch 1%, the balance is distilled water.

[0030] In this embodiment, first, high-fat polypropylene, low-fat polypropylene and color masterbatch are hot-melt mixed, and then emulsifier, wetting agent, wetting agent, spreading agent, antistatic agent and polyether silicone oil are added and mixed Melt, the main components of the middle non-woven fabric are high-fat polypropylene and low-fat polypropylene, which makes the formed middle non-woven fabric have larger pores and improves the water absorption and air permeability of the middle non-woven fabric. By adding a certain proportion of polypropylene Ether silicone oil can effectively improve the water absorption performance of the non-woven fabric, and ...

Embodiment 3

[0032] Internal non-woven fabric, including the following percentages by mass: high-fat polypropylene 10%, low-fat polypropylene 70%, emulsifier 0.6%, wetting agent 0.3%, wetting agent 0.3%, spreading agent 0.3%, antistatic Agent 1%, polyether silicone oil 0.2%, color masterbatch 1%, the balance is distilled water.

[0033] In this embodiment, first, high-fat polypropylene, low-fat polypropylene and color masterbatch are hot-melt mixed, and then emulsifier, wetting agent, wetting agent, spreading agent, antistatic agent and polyether silicone oil are added and mixed Melt, the main component of the middle non-woven fabric is low-fat polypropylene, which makes the inner non-woven fabric have large pores after forming, and improves the water absorption and air permeability of the inner non-woven fabric. By adding a certain proportion of polyether silicone oil, it can effectively improve The water absorption performance of the non-woven fabric is improved, and then the melt is spr...

Abstract

The invention is applicable to the technical field of composite elastic non-woven fabric, and provides composite elastic melt-blown non-woven fabric and processing method thereof. The composite elastic melt-blown non-woven fabric comprises the following materials in percentage by weight: 10%-70% of high-fat polypropylene, 10%-70% of low-fat polypropylene, 0.6% of emulsifier, 0.3% of a wetting agent, 0.3% of a spreading agent, 1% of an antistatic agent, 0.2% of polyether silicone oil, 0.4% of graphene, 1% of color master batch and the balance of distilled water. According to the present composite elastic melt-blown non-woven fabric and the processing method thereof, on the premise of ensuring that the external waterproof performance is not reduced, the internal water absorption performanceis improved, the present composite elastic melt-blown non-woven fabric replaces cotton cloth in some fields, and the application field of the non-woven fabric is widened.

Description

technical field [0001] The invention belongs to the field of composite elastic nonwoven fabrics, and in particular relates to a melt blown composite elastic nonwoven fabric and a processing method thereof. Background technique [0002] Non-woven fabric (English name: NonWovenFabric or Nonwovencloth), also known as non-woven fabric, is composed of oriented or random fibers. It is called cloth because of its appearance and certain properties. Non-woven fabrics are moisture-proof, breathable, and flexible , light weight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in color, low in price, and recyclable. It is produced by continuous one-step laying and hot-pressing coiling. [0003] Non-woven fabrics have the advantages of low price and good water resistance, but whether in the field of clothing or medical treatment, poor water absorption is one of the factors that prevent non-woven fabrics from replacing cotton fabrics.
