Characteristics, identification and application of PP spunbond nonwoven fabric

1. Characteristics of PP spunbond nonwoven fabric
PP spunbond nonwoven fabric, also known as polypropylene spunbond nonwoven fabric, is a nonwoven fabric made of polypropylene (PP) through high-temperature melting, spinning, web forming and hot rolling bonding processes. It has the following significant characteristics:

Lightweight and high strength: PP spunbond nonwoven fabric has low density, light weight, and is easy to transport and use. At the same time, it has good tensile strength and tear strength, and can withstand certain external forces.
Good air permeability: Its fiber structure is porous, allowing air to pass smoothly, so it has strong air permeability and is suitable for scenes that require ventilation.
Strong chemical stability: PP spunbond nonwoven fabric is resistant to acid and alkali corrosion, not easily corroded by chemical substances, and can maintain stable performance in a variety of environments.
Environmentally friendly and recyclable: As an environmentally friendly material, PP spunbond nonwoven fabric can be naturally degraded, non-toxic and odorless when burned, which meets the current social requirements for sustainable development and environmental protection.

2. Identification method of PP spunbond non-woven fabric

Observe the appearance and glossiness
PP spunbond non-woven fabric is produced with brand-new particles, and the glossiness is very good, with a shiny and oily feeling. It feels smooth and will not feel frizzy.
In contrast, non-woven fabrics produced with recycled materials or fillers may have poor gloss and rough feel.
Smell
PP spunbond non-woven fabric is made of polypropylene particles and is odorless. Although there may be an anti-odor during processing, such as the smell of gasoline and diesel, this does not affect the identification of PP spunbond non-woven fabrics.
Other types of non-woven fabrics may have odors due to different raw materials or additives.
Burning test
The powder residue after burning PP spunbond non-woven fabrics will have similar objects, and the burning process is non-toxic and odorless.
The residue after burning other types of non-woven fabrics may vary depending on the raw materials, and some non-woven fabrics may produce toxic gases during the burning process.
Tear test
PP spunbond non-woven fabrics are strong, clean, pure, and have many silks after tearing.
Other types of non-woven fabrics may be loose after tearing and may contain white powdery fillers.
Measuring thickness and specific gravity
By measuring the thickness and specific gravity of the fabric, it can also assist in determining whether it is PP spunbond non-woven fabric. The thickness and specific gravity of PP spunbond non-woven fabrics produced from new materials are usually more uniform.

3. Application areas of PP spunbond nonwoven fabrics

With its unique performance advantages, PP spunbond non-woven fabrics are widely used in many fields:
Medical and health field: PP spunbond non-woven fabric is widely used in the production of medical supplies such as masks, surgical gowns, and medical disposable isolation gowns. Its good air permeability and antibacterial properties provide effective protection for medical staff.
Agricultural field: In agriculture, PP spunbond non-woven fabrics are used as crop coverings, seed bags, weed mats, etc. It can effectively maintain soil temperature and promote crop growth while preventing weed growth and pests and diseases.
Industrial field: In the industrial field, PP spunbond non-woven fabrics are used as filter materials, insulation materials, cement packaging bags, etc. Its excellent chemical stability and strength enable it to maintain stable performance in various industrial environments.
Daily necessities: PP spunbond nonwoven fabrics are also widely used in the production of daily necessities such as shopping bags, packaging materials, and furniture linings. Its light, durable, and environmentally friendly characteristics make it an ideal choice for people's daily lives.
