At present, the non-woven fabrics on the market can be divided into different types according to their different raw materials and processing methods. Among them, PP non-woven fabric, that is, a non-woven fabric made of polypropylene as a raw material through the meltblown method. Because of its lightweight, breathable, heat-resistant, non-flammable, anti-mold and other characteristics, it is widely used in medical and health fields.
PP non-woven fabric itself is hydrophobic and has almost zero moisture content, so it has excellent moisture-proof and antibacterial properties, but in order to use it as a medical device, it needs to be finished with certain protective functions.
1. Non-woven fabric tri-antibody finishing
When PP non-woven fabric is used as a medical device, it is inevitable that it will be stained with alcohol, blood and other liquids during use, and PP non-woven fabric that only has hydrophobic properties cannot prevent these liquids well.
In response to the characteristics of the medical working environment, Guangzhou Lianzhuang Technology Co., Ltd. has developed Texnology®NW-PA. Its main component is fluoroacrylate dispersion, which can be given good anti-alcohol, anti-plasma and anti-water pressure functions to non-woven fabrics such as PP and SMS after being processed by impregnation and drying process.
2. Antistatic finishing of non-woven fabrics
Due to its hydrophobic nature, PP non-woven fabric is easy to generate static electricity, resulting in the adsorption of dust and particles in the air on the surface of the non-woven fabric, causing pollution to medical devices and human wounds. Therefore, it is necessary to apply not only a tri-antibody finish to the nonwoven, but also an antistatic finish.
For example, Texnology®NW16, which is a non-ionic antistatic agent composed of modified organophosphate compounds, can be used in the same bath with non-woven tri-antibody finishing agent, by accelerating the way of charge escape, reducing the situation of static electricity generated by charge accumulation in the same part, so that the non-woven fabric can obtain good antistatic properties on the basis of obtaining the function of tri-antibody.
