Polypropylene: the environmentally friendly choice for spunbond nonwoven interlinings

With the increasing awareness of environmental protection, people are increasingly choosing materials that are environmentally friendly and easy to degrade. In the textile industry, spunbond non-woven interlining is an important material, and its raw material polypropylene has attracted much attention due to its unique environmentally friendly properties. This article aims to explore the environmental advantages of polypropylene as a raw material for spunbond non-woven interlinings and its comparison with polyethylene in terms of degradability.

1. Environmental protection characteristics of polypropylene
Polypropylene (PP) is a thermoplastic resin widely used in the production of spunbond nonwoven interlinings. Its main advantages are good chemical stability, resistance to acid and alkali corrosion, non-toxic and odorless, and processing properties. What's more, polypropylene is a material that degrades relatively easily, a property that gives it significant advantages in terms of environmental protection.

2. Comparison of the degradability of polypropylene and polyethylene
Polyethylene (PE) is the main raw material for disposable plastic products such as plastic bags. Its chemical structure is stable and difficult to degrade in the natural environment. This difficulty in degrading has led to serious environmental pollution problems, such as accumulation of plastic waste and accidental ingestion by marine organisms. In contrast, the chemical molecular structure of polypropylene is easier to break down, which makes it degrade faster in the environment and helps reduce environmental pollution.

Specifically, the degradation of polypropylene mainly occurs through microbial action, photodegradation, thermal degradation and other pathways. Under the action of microorganisms, polypropylene can be broken down into small molecular substances by specific enzymes and eventually be completely mineralized. In addition, polypropylene will undergo a photodegradation reaction under sunlight, causing its molecular chains to break and reduce its molecular weight, thus accelerating its degradation process. These degradation pathways work together to cause polypropylene to degrade significantly faster than polyethylene in the environment.

3. Application of polypropylene in spunbond non-woven interlining
Spunbond non-woven lining is a non-woven material made of polypropylene as the main raw material. Due to the environmentally friendly properties of its raw material polypropylene, spunbond non-woven interlining has significant advantages in environmental protection. It can not only replace traditional disposable plastic products and reduce the generation of plastic waste, but also play an important role in various fields, such as medical and health, clothing, home decoration, etc.

In the medical and health field, spunbond non-woven interlinings are widely used in the production of surgical gowns, masks, protective clothing and other products. Due to its breathability and waterproof properties, spunbond non-woven interlinings can provide effective protection for medical personnel. At the same time, due to their easy degradability, these products will not cause long-term pollution to the environment after being discarded.

In the field of clothing and home decoration, spunbond non-woven interlinings are used as filling materials, fabrics, etc. Their soft and comfortable feel and good breathability make these products popular among consumers. At the same time, due to their environmentally friendly properties, these products are also in line with modern consumers' pursuit of environmental protection and sustainable development.

As a raw material for spunbond non-woven linings, polypropylene has environmentally friendly properties that are relatively easy to degrade. Compared with polyethylene, the chemical molecular structure of polypropylene is easier to break down, helping to reduce environmental pollution. Therefore, spunbond non-woven interlining, as an environmentally friendly material, has broad application prospects in the textile industry. We should actively promote the use of environmentally friendly materials such as spunbond non-woven interlinings to jointly protect our beautiful planet home.
