Detailed explanation of the use of non-woven fabrics

+ 查看更多

Non-woven fabrics are classified based on different production processes:

1. Hydro entangled Non-Woven Fabrics: High-pressure micro-fine water jets are sprayed onto one or multiple layers of fiber webs, intertwining the fibers and strengthening the fabric with a certain level of force.

2. Thermal Bonded Non-Woven Fabrics: This method involves incorporating fibrous or powdery thermoplastic bonding materials into the fiber web. The fabric is then heated, melted, cooled, and solidified to achieve reinforcement.

3. Air-Laid Non-Woven Fabrics: Also known as dust-free paper or dry paper making, this technique employs an airflow process to separate wood pulp fibers into single fiber states. The fibers are then collected and bonded onto a forming screen, followed by consolidation to form the fabric.

4. Wet-Laid Non-Woven Fabrics: In this method, fibrous raw materials are dispersed in a water medium, and the fibers are loosened into single fiber states. Different fiber materials can be blended to create a fiber suspension, which is then conveyed to the forming mechanism. The fibers are formed into a wet web, consolidated, and solidified to obtain the fabric.

5. Spun bond Non-Woven Fabrics: After polymer extrusion and stretching to form continuous filaments, the filaments are laid down to create a web. The fabric is then consolidated through self-adhesion, thermal bonding, chemical bonding, or mechanical reinforcement methods.

6. Melt-blown Non-Woven Fabrics: The process involves feeding the polymer into an extruder, melting and extruding the polymer, forming fibers, cooling the fibers, laying them down to create a web, and consolidating the web into a fabric.

7. Needle-Punched Non-Woven Fabrics: This dry process utilizes the puncturing action of needles to interlock and strengthen the loose fiber web, resulting in a fabric.

8. Stitch-Bonded Non-Woven Fabrics: Also a dry process, stitch-bonding involves reinforcing fiber webs, yarn layers, non-textile materials (such as plastic films or metal foils), or their combinations using warp knitting loop structures to create the fabric.

Applications:

Non-woven fabrics find various applications, including:

1. Medical and Hygiene: Surgical gowns, protective clothing, sterilization wraps, masks, diapers, wipes, household cleaning cloths, magic towels, non-woven rolls, beauty products, sanitary pads, and disposable sanitary fabrics.

2. Home Decoration: Wall coverings, tablecloths, bed sheets, bedspreads, etc.

3. Apparel: Lining fabrics, fusible interlinings, padding materials, shaped cotton, various synthetic leather base fabrics, etc.

4. Industrial Use: Filter materials, insulation materials, cement packaging bags, textiles, wrapping fabrics, etc.

5. Agriculture: Crop protection fabrics, seedling fabrics, irrigation fabrics, thermal screens, etc.

6. Others: Space cotton, thermal and sound insulation materials, oil-absorbent felts, cigarette filters, tea bags, etc.

Key Features:

Non-woven fabrics have revolutionized traditional textile principles and possess the following characteristics:

- Short production process and high production speed.

- High output and low cost.

- Versatile applications in various industries.

- Multiple sources of raw materials.

Non-woven fabrics have become an essential material in many industries due to their unique properties and versatility. Let's delve deeper into the applications and advantages of non-woven fabrics in different fields.
