Spunlace Nonwoven Fabric, also known as spunlace nonwoven fabric, is widely used in many fields such as medical, health, home, industry, etc. due to its softness, breathability, moisture absorption and environmental protection. In order to further improve the product quality of Spunlace Nonwoven Fabric and meet the growing market demand, optimizing its production process has become the key.
1. Optimize raw material selection
1. Select fiber raw materials
Fiber quality: Select high-quality and high-purity fiber raw materials, such as high-quality wood pulp fiber, polyester fiber, etc., to ensure that the fiber length, strength, fineness and other indicators meet the production requirements to improve the physical properties and appearance quality of the finished product.
Fiber ratio: According to the product use and performance requirements, reasonably adjust the ratio of different types of fibers, such as increasing the proportion of natural fibers to improve skin-friendliness and breathability, or adding functional fibers to enhance antibacterial, antistatic and other properties.
2. Raw material pretreatment
Fiber opening and mixing: Use advanced opening and mixing equipment to ensure that the fibers are evenly dispersed, reduce agglomeration and impurities, and lay a good foundation for subsequent processes.
Humidity control: In the fiber pretreatment stage, the moisture content of the fiber is reasonably controlled to avoid excessive dryness or wetness that affects the fiber entanglement effect and the performance of the final product.
2. Fine process control
1. Hydroentanglement process optimization
Water pressure and water volume control: According to the fiber characteristics and product requirements, the high-pressure water flow parameters of the hydroentanglement machine, including water pressure, water volume and spray angle, are accurately adjusted to achieve effective entanglement between fibers while avoiding fiber damage.
Multi-pass hydroentanglement: The multi-pass hydroentanglement process is adopted to repeatedly impact the fiber web with water flows of different pressures and angles to enhance the bonding force between fibers and improve the strength and uniformity of the product.
2. Drying and shaping
Temperature and wind speed control: During the drying process, the temperature and wind speed in the oven are accurately controlled to ensure that the fiber web is evenly heated and avoid deformation or shrinkage of the product caused by local overheating.
Shaping treatment: Through appropriate tension control and heat treatment, the fiber web is shaped to maintain the dimensional stability and flatness of the product.
3. Equipment upgrade and automation
Introduction of advanced equipment: Regularly evaluate existing production lines and introduce more efficient and accurate production equipment, such as intelligent spunlace machines, automated drying lines, etc., to improve production efficiency and product quality stability.
Automation control system: Establish a comprehensive automation control system to achieve real-time monitoring and remote control of the production process, reduce human errors, and improve production accuracy and response speed.
