With the continuous advancement of technology, the production technology of hot-rolled non-woven fabrics has occupied an important position in multiple fields. This new type of material has gradually become an indispensable part of modern industry and life due to its lightweight, breathable, and good toughness. This article will delve into the working principle, components, main applications, market prospects, and future development trends of hot-rolled non-woven fabric production lines.
Definition and characteristics of hot-rolled non-woven fabric
Hot rolled non-woven fabric is a type of fabric formed by bonding short or long fibers together through heat treatment and mechanical action. Compared with traditional fabrics, hot-rolled non-woven fabrics do not have a warp and weft weaving structure, but rather process fibers into fabric through different technical means such as water jet, hot rolling, etc. Its unique production process results in various excellent characteristics, including:
1. Breathability: Hot rolled non-woven fabric has good air permeability and is suitable for products that require breathing, such as medical supplies and cleaning cloths.
2. High strength: After hot rolling treatment, the bonding force between fibers is significantly improved, making the tensile strength and tear strength of non-woven fabrics much higher than that of general textiles.
3. Lightweight: Compared to traditional fabrics, hot-rolled non-woven fabrics are lighter and easier to transport and operate.
4. Environmentally friendly: Many hot-rolled non-woven fabrics can be made of biodegradable materials, which conforms to the modern concept of green environmental protection.
Components of hot-rolled non-woven fabric production line
The configuration of a hot-rolled non-woven fabric production line is very complex, usually including the following main parts:
1. Raw material preparation system: This part is responsible for pre-processing raw materials (such as polypropylene, polyester, etc.) to ensure that they meet production requirements. The quality of raw materials at this stage will directly affect the performance of the final product.
2. Fiber conveying system: The processed raw materials are sent to the fiber opening machine, and after mechanical opening, the fibers will be evenly conveyed to the web forming machine.
3. Web forming system: There are various web forming technologies, and hot-rolled non-woven fabric production often uses needle punching or water punching to form a web. The former uses needle punching to pass through the fiber web to increase the connection between fibers, while the latter wraps the fibers around each other through water flow.
4. Hot rolling mill: This is the most critical part of the hot-rolled nonwoven fabric production line. By hot rolling, the bonding force between fibers is enhanced, and the thickness and hardness of the fabric can also be controlled by adjusting the temperature and pressure.
5. Coating and post-treatment equipment: According to different usage requirements, hot-rolled non-woven fabrics may require coating treatment, such as adding water resistance, antibacterial and other functions.
6. Roll up machine: After the above steps, the final non-woven fabric will be rolled up for subsequent cutting and packaging.
Application of hot-rolled non-woven fabric
Hot rolled non-woven fabrics are widely used in multiple fields due to their excellent physical properties and flexible production processes
1. Healthcare: In the medical industry, hot-rolled non woven fabric can be used to produce surgical gowns, masks, bed sheets, and disinfectant cloths, which can effectively block bacteria, dust, and liquids, ensuring the safety of medical staff and patients.
2. Personal care: production of products such as baby diapers and feminine sanitary napkins. The softness and high moisture absorption of hot-rolled non-woven fabric make it an ideal choice for such products.
3. Household goods: Hot rolled non-woven fabric is widely used in cleaning cloths, curtains, mattresses and other products. Its durability and versatility have gradually increased its use in home environments.
4. Construction and Vehicle Engineering: As a high-quality insulation material, hot-rolled non-woven fabric has also been widely used in the construction industry, especially in roof insulation and wall insulation.
5. Agriculture: In agriculture, hot-rolled non-woven fabric can be used as seedling sunshade cloth, crop protection cold cloth, etc. It has good breathability and helps plant growth.
