Can You Find Spunlace Nonwovens in Your Life
Spunlace Nonwovens is one of Nonwoven Fabric. When pre-wetted fiber web enters the hydroentanglement zone, the water jet head sprays multiple fine water streams through the water spray holes on the spray plate, perpendicular to the fiber web. The water streams cause displacement of some surface fibers in the web, including vertical movement towards the opposite side of the fiber web. After the water streams penetrate the fiber web, they are rebounded by the support curtain or drum, scattering in different directions on the opposite side of the fiber web. Under the dual effects of the direct impact of water jets and the rebounding water flow, fibers in the web undergo displacement, interweaving, entanglement, and cohesion, forming numerous flexible entanglement points, thereby reinforcing the fiber web. The combination of various fibers in multiple layers forms hydroentangled nonwoven fabric. However, it is not formally referred to as hydroentangled nonwoven fabric simply due to this combination. The reason it is called nonwoven fabric is because it bypasses the traditional textile process, automating it through a spraying mechanism. By combining various fibers through the process of spraying, the durability of the fabric is enhanced, thereby increasing its quality. The concept of ‘jet-spun fabric’ originates from the mechanical needle-punching process. The term ‘jet-spun’ involves using high-pressure water jets to penetrate the fiber web, causing the fibers to intertwine and giving the initially loose fiber web a certain strength and a complete structure. The process involves fiber metering and mixing, opening and cleaning, mechanical chaotic combing into a web, pre-wetting of the fiber web, water jet entanglement, surface treatment, drying, winding, inspection, and packaging for storage. A jet-spun device utilizes high-speed, high-pressure water flow to spray the fiber web, rearranging the fibers, intertwining them, and transforming them into a structurally sound nonwoven fabric with a certain strength and other desirable properties.
Features of Spunlaced Nonwovens
In the hydroentanglement process, there is no extrusion applied to the fiber web, thereby enhancing the fluffiness of the final product. The absence of resins or adhesives preserves the inherent softness of the fiber web. The high overall integrity of the product prevents it from becoming fluffy. The fiber web exhibits a higher mechanical strength, reaching 80% to 90% of the strength of traditional textiles. The fiber web can incorporate a variety of fiber types. Notably, hydroentangled fiber webs can be compounded with any base fabric, creating composite products. Various functional products can be produced according to different purposes.
- Soft and has good drape.
- High strength.
- Exhibits high moisture absorption and quick-drying properties.
- Low tendency to pill.
- Wash-resistant.
- Free from chemical additives.
- Appearance resembles textiles.
Application of Spunlaced Nonwovens
Due to the advantages of hydroentangled fabric, it has become one of the fastest advancing areas in non-manufacturing technological progress in recent years. The development direction of nonwovens is to substitute for woven and knitted textiles. Hydroentangled fabric, with its textile-like characteristics, excellent physical properties, and cost-effectiveness, has emerged as the most promising contender in the textile market.
- Medical Sector: Disposable surgical gowns, surgical cover fabrics, operating table covers, surgical aprons, etc. Wound dressing materials, bandages, gauze, adhesive bandages, etc. Apparel:
- Clothing linings, baby clothes, training suits, disposable festive attire, various protective clothing such as surgical gowns, etc.
- Wiping Cloths: Household, personal, beauty, industrial, medical wipes, etc.
- Decorative Fabric: Automotive interiors, home decor, stage decorations, etc.
- Agricultural Use: Thermal greenhouse covers, weed control fabric, harvest cloth, insect-proof and preservation fabric, etc.
- Composite Processing: Hydroentangled nonwoven fabric can be used for composite processing, producing products with a “sandwich” structure. It can be developed into a variety of new composite materials for different purposes.
