What Is PLA Non-woven Fabric?

What is PLA non-woven fabric?

PLA non-woven fabric is an industrial fabric made of a new type of bio-based material, also known as: polylactic acid non-woven fabric, biodegradable non-woven fabric, corn fiber non-woven fabric. Its biggest feature is that it is biodegradable, friendly to the ecological environment, and will not cause chemical poisoning. In nature, it can be gradually decomposed by microorganisms in the environment until completely decomposed into water and carbon dioxide, without producing other components that pollute the environment.

What are the characteristics of PLA non-woven fabric?

1. It has biodegradable characteristics, so it greatly reduces the impact on the environment; it can completely degrade into carbon dioxide and water, reducing carbon emissions.

2. The material is soft and uniform, so it is used in the medical industry, decoration industry, and machinery industry.

3. It has good breathability, so it can be used to make ointments and masks.

4. It has good water absorption, so it is used in diapers, incontinence pads, sanitary wipes, and daily chemical products.

5. It has a certain antibacterial effect because it is weakly acidic and can balance the human body environment to inhibit the reproduction of bacteria, so it is often used to make disposable underwear and disposable hotel bed linen.

6. It has certain flame retardant properties, which is better than polyester or polypropylene film.

What is the use of PLA non-woven fabric?

1. It can be used as a ground film, using 30-40g/㎡ of PLA non-woven fabric to replace traditional plastic film for covering Dapeng, because it is light in weight, resistant to pulling, and has good breathability, so it does not need to be uncovered for breathability during use, saving time and effort. If you need to increase the humidity inside the shed, you can also sprinkle water directly on the non-woven fabric to maintain humidity.

2. Used in the medical and health industry, such as masks, protective clothing, and caps; daily necessities such as sanitary napkins and diaper pads.

3, It can also be used to make handbags and disposable bed sheets, covers, headrests and other daily necessities.

4. It is also widely used in agricultural planting as a seedling bag, such as using it for protection when breeding, its breathable and water-permeable characteristics, and high strength, are very suitable for plant growth.

The difference between PLA non-woven fabric and polypropylene non-woven fabric

1. Different raw materials: The PLA non-woven fabric uses biodegradable PLA, which is made from starch raw materials extracted from renewable green plant resources such as corn. After use, it can be completely degraded by microorganisms in nature, ultimately generating carbon dioxide and water, which does not pollute the environment. This is very beneficial for environmental protection and is a widely recognized environmentally friendly material. On the other hand, the polypropylene non-woven fabric is made of polypropylene, which has poor light resistance compared to PLA non-woven fabric.

2. Different uses: PLA non-woven fabrics are mostly used in agricultural planting and medical and health fields, while polypropylene non-woven fabrics are only used in dust bags, filter materials, and industrial fabrics.

Degradation principle of PLA non-woven fabric

PLA non-woven fabric is not produced using petrochemical raw materials, but is produced using completely biodegradable plant raw materials, so it can better protect the environment, because its initial raw materials are plant starch, which will gradually decompose into carbon dioxide and water under the action of microorganisms, and its raw materials are renewable resources, so it is very environmentally friendly from raw materials to finished products. So its degradation process is decomposed under the action of microorganisms, during which no harmful substances will be produced.
