The most common use of PP SSS (Spunbond + Spunbond + Spunbond) spunbond machine is for producing nonwoven fabrics. PP SSS spunbond nonwoven fabric is a type of fabric made by bonding together polypropylene fibers through a process of melting, extrusion, and spinning.
PP SSS spunbond fabric is known for its high tensile strength, durability, and water resistance, and it is commonly used in a wide range of applications, including:
- Disposable medical products such as surgical gowns, masks, and drapes.
- Protective clothing and industrial textiles such as coveralls, aprons, and bags.
- Geotextiles for soil stabilization and erosion control.
- Agriculture products such as crop covers, plant protection mats, and nursery over-wintering.
- Automotive industry for interior trims, China PP SSS Spunbond Machine supplier insulation, and filters.
- Home furnishings such as furniture upholstery, bedding, and carpet backing.
PP SSS spunbond machine is widely used because it can produce nonwoven fabrics in large volumes, at high speeds, and with low manufacturing costs.
At what temperature does PP SSS Spunbond Machine degrade?
PP (polypropylene) SSS (Spunbond + Spunbond + Spunbond) is a nonwoven fabric made by a type of meltblown process using polypropylene as the raw material.
Polypropylene has a melting point of approximately 160-170°C (320-338°F) and starts to degrade at temperatures above 200°C (392°F). However, the actual temperature at which PP SSS spunbond machine will degrade will depend on various factors such as the specific composition of the polymer, the processing conditions, and the duration of exposure to high temperatures.
In general, PP SSS spunbond fabric is typically produced at a temperature range of 240-280°C (464-536°F), which is below the degradation temperature of polypropylene. Therefore, under normal production conditions, PP SSS spunbond fabric should not degrade.
