What is Polypropylene Spunbond Nonwoven Fabric? Is PP Spunbond Nonwoven Fabric Biodegradable?
We wish to believe that there are not many people out there who are unaware of the benefits and usage of PP or Polypropylene. And why not, this thermoplastic polymer resin is one of the popular plastic varieties and plenty of industrial, commercial, household, healthcare, and fashion-textile applications.
When it comes to the eco-friendliness of non-woven these have exceptionally popular and biodegradable and non-toxic options relative to the other alternatives. Let us analyze Polypropylene, non-woven fabrics, and its benefits and biodegradability in detail.
Let us begin from understanding the polymer from the scratch by understanding:
What is Polypropylene?
Polypropylene is a multi-variety plastic with the addendum that it is among those varieties in which the toll on the environment is the least. This is the reason why Polypropylene is one kind of polymer gaining popularity across industries due to its inert properties and environment-friendly features.
What are the best features of Polypropylene?
Some of the best features of Polypropylene are:
- PP or polypropylene fabrics are extremely durable and resistant to abrasion and wear, which makes them a favourite
- among the manufacturing, industrial, and textile/ upholstery industry.
- It can withstand repeated and long-term use the PP fabric also is stain resistant.
- PP fabric has the lowest thermal conductivity of all synthetic or natural claiming it as an excellent insulator.
- Polypropylene fibers are resistant to sunlight to when dyed it is fade resistant.
- PP fabric is resistant to fabric bacteria and other microbes and has a high level of endurance with moths, mildew, and molds.
- It is difficult to ignite polypropylene fibres. They are combustible; however, not flammable. With specific additives, it becomes fire-retardant.
- Additionally, polypropylene fibres are also resistant to water.
Owing to these immensely benefits you can understand why polypropylene is much popular material with innumerable applications across industries globally.
What is Polypropylene Spunbond Nonwoven Fabric?
Spun laid commonly known as Spunbond Nonwoven fabric are made up of the continuous process of fibres spun and directly dispersed into a web-like deflector or can be directed with air streams. This process leads to a faster belt speed.
Mainly, these are prepared in a sheet or web structures bonded by entangled fibres or filaments by thermal or chemical treatments, as required by the Spunbond Fabric Supplier or Spunbond Fabric Manufacturer.
Non-woven polypropylene fabric is thermoplastic polymer like PP or Polypropylene; however, it is manufactured to look non-woven. It has main applications in non-woven bags, interlining, healthcare coveralls, masks, filters, etc. It is gaining rising popularity in the healthcare and fashion industry.
With new gaining policies sweeping the globe in their attempt in reducing plastic pollution, non-woven bags and packaging materials is the new norm prevailing in many countries.
Is Polypropylene Spunbond Non-woven Fabric waterproof?
Being low linear density polyethylene [LLDPE] with a high branching ratio, it has good flexibility, water permeability, resistance, softness, and low-temperature resistance and it also has features like being water-resistance/ waterproof.
Characteristics of Polypropylene Non-woven Spunbond fabric – Waterproof Traits:
- It is a three-layered structure with an advanced surface.
- It has a primary waterproofing layer with low-density polyethylene and a high branching ratio with good flexibility, water permeability, softness, and resistance.
- It has low-temperature resistance.
- The surface of the non-woven fabric is PP polyester, it can be used to resolve the issue of composite materials and cement bonding with combining core layer the defect of large polyethylene linear expansion coefficient can be solved.
What are the characteristics of Polypropylene Dewatering Non-Woven Fabric?
PP dewatering Non-woven fabric has strong impermeability, high tensile strength, flexibility, good stability, strong deformation compatibility, wide temperature range, long service life, non-toxic, strong deformation compatibility, with chemical resistance, corrosion, mildew, and ozone properties to sum up.
What are the best Applications of Polypropylene Dewatering Non-Woven Fabric?
- The Best applications are waterproof polymer is used brilliantly in special concrete and cement to be closed.
- As it can be bonded directly to the wire, it is not affected by the base moisture during the manufacturing process.
- Because of its high rough surface thickness and high friction of polymer composite material it can be buried directly in the sand and has stability when used in water conservation projects as well.
- It can be directly bonded with the cementitious materials in the solidification process and directly designed into the cementitious structure.
Owing to its high applications in a variety of industries and most critical ones it is high in demand across industries.
Is Spunbond Non-woven Fabric Eco-friendly – Biodegradable or recyclable?
It is often a point of discussion that whether the non-woven fabric is biodegradable or not? In most cases, it depends upon the types of nonwoven made from various types of fibres. The type of fiber primarily determines whether a nonwoven fabric is biodegradable or not.
In most cases, Spunbond Polypropylene fabric is used in most of the day-to-day applications. And as against popular notion, PP or polypropylene is not biodegradable, having said that Spunbond can be produced with biodegradable fibres; however, it is a small market as biodegradable fibers are twice as expensive as Polypropylene.
Nonwoven bags are recyclable. Hence, it can be claimed that nonwoven bags are environmentally friendly. Spunbond polypropylene fabrics do not harm the environment and they are environment friendly than plastic products.
This question of whether PPE is eco-friendly or not is nothing new. Although science and experience claim that this material is among the most sustainable ones, we have at present to cater to a variety of industries for various applications. However, this is just a silver lining the entire picture is rather grim. PPR items still reach landfills instead of recycling plants although some companies are taking initiatives and taking steps forward. There are UN Sustainable Development goals also for which many companies are working collectively.
