Water-resistant Non-woven Polypropylene
What is Non Woven Polypropylene Fabric?
Non Woven Polypropylene Fabric refers to the polypropylene polymer is spun into microfiber by heating melting and air ejecta, and then the fluffy thread is hot-pressed into polypropylene fabric. The fabric produced in this way has a woven texture, flexibility and strength. Waterproof fabric is a material that has been finished and then made waterproof. The fabric is very versatile. It can be used in many fields, such as medical, Marine applications, etc. We can use waterproof fabric to make items that need waterproof, like raincoats or tents.
Waterproof properties of polypropylene fabrics
In practice, not all polypropylene fabrics are water-resistant. Depending on how polypropylene fabrics are made (woven or nonwoven), their water-resistant properties and levels will vary. Let's take a look at the waterproof properties of different polypropylene fabrics:
Woven polypropylene fabric: woven by machine, water molecules are easy to penetrate through the gaps of woven cloth, so it does not have waterproof properties. If you want to make woven polypropylene to improve waterproof performance, you can cover the surface with a layer of film or add a layer of PVC material on the surface, so as to achieve waterproof, moisture-proof, oil-proof effect.
Non-woven polypropylene fabric: depending on the way it is made, it also has different degrees of water resistance. Polypropylene fabric, for example, which is made by squeezing fluffy fibers with a hot press, has the property of blocking water molecules, but also has a certain permeability. In addition, the non woven polypropylene fabric can also be added with some waterproof treatment, so that the fabric can obtain a higher degree of water resistance.
Water-resistant Non-woven Polypropylene
In daily life, Water-resistant Non-woven Polypropylene is often used to make reusable tote bags, shopping bags, clothing bags and other items.
Water-resistant Non-woven Polypropylene is also used in the medical and health field, commonly used as a filter in masks, and wound bandages. In addition, Water-resistant Non-woven Polypropylene is also used as a covering cloth, isolation cloth applied in the garment manufacturing industry and indoor decoration industry, for example, as a sofa and other furniture isolation cloth, and outdoor clothing waterproof isolation cloth.
Why is polypropylene fabric waterproof？
Polypropylene is a thermoplastic polymer, and one of the reasons why polypropylene fabrics are waterproof is because they retain the properties of polypropylene as a synthetic resin. Although polypropylene is widely used as a plastic material, it also has soft properties that allow it to be used as woven or non-woven fabrics.
The chemical structure of polypropylene makes it waterproof. The areas covered by polypropylene are impermeable to water analysis, but if there are cracks or openings in the articles covered by polypropylene, water molecules can damage the polypropylene through the openings and gaps.
In addition, polypropylene also ages over time, and its inherent waterproof properties degrade over time.
What are the advantages of waterproof polypropylene fabric？
1. Lightweight and soft material.
2. Eco-friendly. The environmental damage from waterproof polypropylene fabric waste is very low.
3. Waterproof and breathable. The waterproof polypropylene fabric has good water resistance and good air permeability. It can keep the surface dry and easy to clean.
4. It can be reused.
5. Non-toxic and antibacterial. The raw material of waterproof polypropylene fabric is non-irritating. It does not contain other harmful chemical components to the human body.
6. Low price and cost-effective. Waterproof polypropylene fabric can be customized in size, custom pattern, and logo.
