Embodiment 1

[0020] Proportion: polypropylene resin 98%

[0021] Polypropylene hydrophilic masterbatch 2%

[0022] Application: covering cloth for agriculture

[0023] Polypropylene spun-bonded non-woven fabric has widely replaced PE cover film (impermeable air) due to its good air permeability, but its water repellency limits dew to moisten crops. After using this polypropylene hydrophilic spun-bonded non-woven fabric The dew can penetrate evenly, so that the crops can be moistened with dew, ensuring that the crops are more natural and green.

Embodiment 2

[0025] Proportion: polypropylene resin 96%

[0026] Polypropylene hydrophilic masterbatch 4%

[0027] Application: air purification filter bag

[0028] With the development of electronics industry, bioengineering, and medical industry, many products need to be manufactured in clean rooms, which requires air purification and filtration.

[0029] And because polypropylene spun-bonded non-woven fabric has the characteristics of good air permeability, high strength, non-toxic, harmless and environmental protection, it is widely used as the base fabric of filter bags.

[0030] However, due to its water repellency, when the air passes through the activated carbon and other filter layers, the accumulated water cannot pass through and accumulate, thereby reducing the air filtration capacity, greatly reducing the service efficiency and life of the filter bag, and the cost remains high. Using this polypropylene hydrophilic non-woven fabric as the filter bag of the base fabric, the acc...

Embodiment 3

[0032] Proportion: polypropylene resin 94%

[0033] Polypropylene hydrophilic masterbatch 6%

[0034] Use: mask

[0035] The air exhaled by people contains a lot of water. When the temperature is low and the temperature difference is large, the exhaled air will condense into water and cannot pass through the general polypropylene spunbonded non-woven fabric layer. Feeling very uncomfortable and easy to breed bacteria.

[0036] The mask produced by this polypropylene hydrophilic spunbond fabric can let water vapor out, keep the face of the human body dry, comfortable and hygienic.

Abstract

The present invention relates to a hydrophilic polypropylene spun-bonded nonwoven fabric. It is characterized by that it is formed from polypropylene resin and polypropylene hydrophilic mother granules, and its mixing ratio is 94%-98% of polypropylene resin and 2%-6% of polypropylene hydrophilic mother granules.

Description

technical field [0001] The invention relates to a hydrophilic polypropylene spun-bonded non-woven fabric. Background technique [0002] Polypropylene spunbonded non-woven fabric is made of polypropylene resin by melting, extrusion spinning (filament), laying net and hot rolling. [0003] Due to the characteristics of non-toxic, harmless and environmentally friendly, good air permeability, smooth and smooth surface, polypropylene spunbonded non-woven fabrics are widely used in medical and health care, household products, clothing industry, leather, industry and agriculture, civil engineering and other fields. . However, due to the water repellency of the polypropylene spunbonded nonwoven fabric, its application is limited. In order to change its water repellency, there are two main types of hydrophilic polypropylene spunbonded nonwoven fabrics developed in the prior art: [0004] One is made of hot-air staple fiber non-woven fabric sprayed with hydrophilic additives, and it...
