Product Description
Pre-oxygenated staple spunlace nonwovens
Composition and Manufacturing Process
- Composition: They are mainly composed of pre-oxygenated staple fibers. Pre-oxygenated fibers are those that have undergone pre-oxidation treatment. Usually, fibers such as polyacrylonitrile (PAN) fibers are processed under certain temperatures and in an oxidizing environment, which causes changes in the chemical structure of the fibers and endows them with special properties like flame retardancy and high-temperature resistance.
- Manufacturing Process: The spunlace process is adopted. In the spunlace process, high-pressure fine water jets are sprayed onto one or more layers of fiber webs, causing the fibers to interlock with each other and form nonwovens. During this process, the pre-oxygenated staple fibers are intertwined and entangled under the action of the water flow to form nonwovens with a certain strength and a uniform structure.
Performance Characteristics
- Good Flame Retardant Performance: Due to the flame retardant properties of pre-oxygenated fibers themselves, these nonwovens have relatively high flame retardancy. Their Limiting Oxygen Index (LOI) is relatively high. When encountering an open flame, they can effectively prevent the spread of the flame and form a carbonized layer instead of burning like ordinary fibers, which greatly improves the safety in use. They can be used in occasions with high requirements for fire prevention, such as firefighter uniforms and fireproof curtains.
- Moderate Mechanical Properties: They have a certain degree of strength and toughness. The spunlace process makes the fibers tightly intertwined, enabling them to withstand certain mechanical forces such as tension and tearing. However, compared with some traditional woven fabrics, their strength may be slightly lower, but it is sufficient to meet many daily application scenarios, such as being used as packaging materials and wiping materials.
- Softness and Comfort: The spunlace process makes the nonwovens have good softness and a comfortable touch. This enables them to perform well in some application scenarios where they come into contact with the human body, such as medical supplies and hygiene products. Meanwhile, they also have good air permeability and won't make people feel stuffy.
- Good Chemical Stability: They have a certain tolerance to chemical substances such as acids and alkalis. This is because the chemical bond structure of pre-oxygenated fibers themselves is stable and is not easily damaged by chemical reactions when in contact with chemical reagents. In application scenarios such as chemical filtration, they can take advantage of their chemical stability.
Application Fields
- Firefighting and Security Protection Field: They are used to make protective equipment such as firefighter uniforms, fireproof gloves, and the linings of fireproof helmets, providing effective fire protection for firefighters and others. Meanwhile, they can also be used to make fireproof curtains and fireproof drapes in public places to improve the fire safety of buildings.
- Medical and Health Field: Due to their softness, air permeability, and chemical stability, they can be used to make medical dressings, surgical drapes, masks and other medical supplies. In wound care, they can provide a relatively gentle and breathable environment that is beneficial to wound healing.
- Daily Goods Field: As a soft and comfortable material, they can be used to make disposable wipes for cleaning homes, electronic devices, etc. They can also be used as packaging materials for packaging some products with certain requirements for fire prevention and moisture prevention.
