The outer layer of disposable masks is generally made of PP spunbond non-woven fabric as the raw material, which has the following characteristics:
Breathability: Due to the mesh structure of PP spunbond non-woven fabric, it has good breathability, allowing people to breathe smoothly while wearing masks.
Lightweight and Soft: PP spunbond non-woven fabric is lighter, thinner, and softer than traditional materials such as cotton and linen, which can better fit the face and not burden people.
Environmentally friendly and recyclable: PP spunbond non-woven fabric is made of recyclable polypropylene (PP) fibers, which have good sustainability and environmental friendliness, in line with the concept of green environmental protection.
Good tensile strength: PP spunbond non-woven fabric material has excellent tensile strength, which can effectively prevent mask cracking and improve the service life of masks.
Good waterproof performance: PP spunbond non-woven fabric material has a high surface density, which can effectively prevent water droplets from penetrating and play a certain waterproof role.
Weak moisture absorption performance: Due to the fact that PP spunbond non-woven fabric does not contain natural fibers, its moisture absorption performance is weak, but it does not have much impact on the application scenario of disposable masks.
PP spunbond non-woven fabric is a material that is very suitable as the outer layer of medical cloth for disposable masks. It has good breathability, lightweight and soft, and good tensile strength, which can effectively improve the performance and service life of masks.
The outer layer of disposable masks is generally made of PP spunbond non-woven fabric as the raw material, and its production process is as follows:
Material preparation: Prepare polypropylene (PP) particles and other auxiliary materials such as additives.
Melt spinning: Heating polypropylene to its melting point and extruding it from microporous plates or spinnerets through spinning equipment to form a continuous fiber flow.
Preparation of grid structure: The continuous fiber flow obtained by spinning is introduced into the grid structure preparation equipment, and it is formed into a grid structure through heating, stretching and other processes, further improving strength and tensile resistance performance.
Spin bonding: Introduce a flow of polypropylene fibers with a grid like structure into the spin bonding chamber, while spraying a spin bonding agent and black dye into the fiber flow to solidify the fibers and form a black spunbond non-woven fabric.
Treatment: Treat the PP non-woven fabric obtained by spunbond, including anti-static treatment, antibacterial treatment, etc.
Making the outer layer of the mask: Cut the processed PP non-woven fabric into the outer layer of the disposable mask for medical use.
Packaging and storage: The outer layer of medical cloth that meets the quality requirements of the mask will be packaged and stored in a dry, ventilated, and non corrosive gas warehouse to ensure the shelf life and quality of the product.
It should be noted that the specific production process may vary depending on the manufacturer and product type. During the production process, it is also necessary to strictly control parameters such as temperature, humidity, and spinning speed to ensure the quality and performance of PP spunbond non-woven fabric. In addition, to meet specific application requirements, different material formulations and process parameters can be selected according to the requirements to improve strength, tear resistance, and durability.
