Chemical bonded non-woven fabric is a material that combines fibers through a chemical process and is widely used in many fields, such as medical, automotive, construction and home furnishings. Its remarkable high temperature tolerance and excellent physical properties have given it a niche in the market.
1. Material composition
chemical bonded non-woven fabrics usually use polyester (PET) as the main raw material, and their high temperature resistance can reach 260°C. After high-temperature carding treatment, they can maintain good structural stability. In addition, some products will also use viscose as raw materials to provide different feel and performance.
2. Performance characteristics
High temperature resistance: Due to its ability to withstand temperatures up to 260°C, chemical bonded nonwovens excel in applications requiring high temperature processing, which is particularly important in automotive interiors and building insulation.
Good mechanical strength: chemical bonded non-woven fabrics usually have high tear strength and tensile strength, which can meet the requirements of various industrial applications.
Breathability and comfort: Despite its high temperature resistance, high-quality chemical bonded non-woven fabrics can still maintain good breathability and are suitable for use in medical and hygiene products such as disposable clothing and mattress protectors.
3. Product classification
chemical bonded non-woven fabrics are generally divided into three categories according to different tactility:
S grade (Soft): soft to the touch, suitable for products close to the skin, such as medical dressings and comfortable home textiles.
M grade (Medium): moderate feel, good strength and wear resistance, commonly used in daily household and light industrial products.
Grade H (Hard): Harder to the touch, mainly used in applications that require extra strength and stability, such as automotive interiors and building materials.
4. Application areas
The wide range of applications for chemical bonded nonwovens makes them ideal for several industries:
Medical: Used in surgical gowns, disposable gowns and dressings to provide hygienic protection.
Automotive: As an interior material, providing sound insulation and fire protection.
Construction: Used in insulation and vapor barriers to improve the energy efficiency and comfort of buildings.
5. Environmental friendliness
The production process of modern chemical bonded non-woven fabrics is increasingly environmentally friendly. Many manufacturers use renewable materials and are committed to reducing waste and pollution during the production process, in line with the requirements of sustainable development.
