Plain Spunlace Nonwoven Fabric Product

I. Process Flow of Plain Spunlace Nonwoven Fabric

 The core of plain spunlace nonwoven fabric is to create a uniform and smooth surface structure through precise processes. Changshu Yongdeli Spunlaced Nonwoven Fabric Co., Ltd. ensures the smoothness and performance consistency of each batch of products through full-process refined control. The specific process is as follows:

 Raw material selection and blending: According to the performance requirements of the application scenarios, high-quality fiber raw materials are carefully selected. Common types include polyester, viscose fiber, pure cotton fiber, bamboo fiber, or blends of multiple fibers (such as polyester-viscose blends, cotton-polyester blends). The technical team scientifically adjusts the fiber ratio. For example, in the hygiene products scenario, the proportion of viscose fiber is increased to enhance skin-friendliness; in the industrial scenario, the proportion of polyester is increased to enhance wear resistance, ensuring the basic performance and applicability of the product from the source.

Opening and blending: The baled fiber raw materials first enter the opening equipment, where mechanical forces are used to disperse the fiber bundles and remove impurities and short fibers. The fibers then enter the blending equipment in the preset ratio and are uniformly mixed through multiple sets of stirring devices to avoid fiber agglomeration or uneven distribution, laying the foundation for the smoothness of the subsequent carding and web formation.

Carding and web formation (key control for smoothness): The mixed fibers enter a high-precision carding machine, where the needle components rotate at a specific speed to finely comb, straighten, and orient the fibers. Compared to other textured spunlace nonwoven fabrics, plain products have higher requirements for the carding process. Technicians adjust parameters such as the density of the needle components and the speed of the rollers in real time to ensure that the fibers are evenly spread on the web-forming screen, forming a continuous, uniform (with thickness deviation controlled within ±1.5%), and defect-free plain base web. This is the core prerequisite for ensuring the smoothness of the final fabric surface.

Plain spunlace reinforcement: The plain web formed by carding is conveyed to the spunlace machine, which is a key process for forming the plain structure. The spunlace machine uses multiple sets of high-pressure water jets to spray high-pressure water (6-12 MPa) vertically or at a small angle. When the water acts on the web, it causes the fibers to entangle and interweave. Unlike other textured spunlace processes, the water jets in plain spunlace are arranged more regularly, and the water spray angles and pressure distributions are more uniform, ensuring consistent fiber entanglement density and avoiding local fiber accumulation or sparseness. The final product has a smooth and uniform plain weave structure. Technicians monitor the water pressure, spray frequency, and web running speed in real time to ensure consistent reinforcement effects across the entire fabric surface.

Dewatering and drying: The wet plain nonwoven fabric after spunlace reinforcement is first sent to a vacuum dewatering device, where negative pressure is used to remove 70%-80% of the water from the surface, reducing the energy consumption of the subsequent drying process and avoiding excessive water causing fabric wrinkles. Then, the dewatered nonwoven fabric is sent to a hot air drying device and dried at a constant temperature of 80-110°C and a stable air speed, ensuring that the product's moisture content is controlled within 5%. During the drying process, a flat-laying conveying method is adopted, combined with precise temperature and wind speed control, to prevent fabric shrinkage and wrinkling, and further ensure the flatness of the plain structure.

Post-treatment and slitting: According to the individualized demands of customers, post-treatment is carried out on the plain spunlace nonwoven fabric after drying. Common processes include hydrophilic treatment (to enhance the liquid absorption speed and liquid retention capacity of hygiene products), antibacterial treatment (suitable for medical and hygiene scenarios to inhibit bacterial growth), softening treatment (to enhance the comfort of skin-contact products), and antistatic treatment (to meet the electrostatic control requirements of the electronics industry). After post-treatment, the products enter the slitting equipment and are precisely slit according to the pre-set width (1-3.2m), length or roll specifications by the customer, ensuring that the dimensional error of the finished products is less than ±0.5cm, meeting the processing and usage requirements of downstream customers.

Quality inspection and warehousing: The quality inspection focuses on the "plain characteristics" and basic performance. In addition to the routine appearance inspection (checking for defects, color differences, and wrinkles on the fabric surface) and physical performance inspection (tensile strength, elongation at break, and abrasion resistance), an additional "fabric flatness inspection" is added, measuring the fabric surface undulation with a laser flatness tester (controlled within 0.2mm/m) to ensure compliance with plain weave product standards. At the same time, key indicators such as breathability and moisture absorption are sampled for inspection. Only qualified products can be warehoused for shipment, ensuring that every batch delivered to customers is of reliable quality.

II. Advantages of Plain Spunlace Nonwoven Fabric

Excellent fabric flatness: Through precise carding and uniform water jet bonding, the fabric surface is smooth and fine, without obvious texture undulations or fiber accumulation, and has high thickness uniformity (deviation less than ±2%). This flatness ensures precise positioning during subsequent processing (such as printing, laminating, and cutting), reducing processing deviations caused by fabric unevenness, especially suitable for scenarios with high requirements for appearance and processing accuracy (such as surface printing of hygiene products and cutting of medical dressings).

Balanced and stable performance: The uniform fiber entanglement density of the plain structure results in small differences in longitudinal and transverse strength (strength difference less than 15%), and balanced distribution of tensile, abrasion, and breathability performance across the fabric surface, without local performance weak points. During use, it can stably withstand external forces without local tearing or damage, suitable for basic application scenarios with high requirements for performance stability.

Good skin-friendliness and comfort: The plain fabric surface has no obvious raised textures, providing a smooth and fine touch, without friction or irritation when in contact with the skin. If natural fibers (such as pure cotton, viscose, and bamboo fiber) are used as raw materials, the skin-friendliness of the product is further enhanced, effectively reducing discomfort reactions in sensitive skin individuals, particularly suitable for direct skin contact scenarios such as hygiene products, medical dressings, and home intimate products.

Wide processing compatibility: The flat fabric structure provides excellent processing compatibility, easily adapting to various processing techniques such as printing, laminating, cutting, sewing, and heat sealing. For example, during printing, the ink adheres evenly without issues like missed printing or bleeding due to fabric undulations; when laminated with films or other nonwoven fabrics, there are no air bubbles and high lamination strength; during cutting, the edges are neat without fraying, significantly reducing the processing difficulty and cost for downstream customers.

III. Characteristics of Plain Spunlace Nonwoven Fabric

Classic structure with strong applicability: The plain is the most basic and classic fabric texture structure, requiring no complex texture design yet meeting the basic application needs of multiple industries. Whether used as the surface layer of hygiene products, the base material of medical dressings, or the basic material of industrial wiping cloths, plain spunlace nonwoven fabric can adapt to diverse scenarios with balanced performance and a flat surface, making it an extremely versatile nonwoven fabric product. Environmentally friendly and residue-free, with high safety: The production process only uses physical water-jet technology to entangle fibers, without adding chemical substances such as adhesives, fluorescent agents, or formaldehyde, thus avoiding potential harm to human health from chemical residues. The products have been tested by authoritative institutions and comply with environmental and safety standards such as GB 18401-2010 "National Basic Safety Technical Specifications for Textile Products". If natural fiber raw materials are used, the products can be naturally degraded after disposal (with a degradation rate of over 85%), aligning with the trend of green development and suitable for high-safety-demand scenarios such as medical and infant care products.

Flexible performance adjustability: Although the plain structure is fixed, the strength, breathability, moisture absorption, and wear resistance of the product can be flexibly adjusted by changing parameters such as the type and ratio of fiber raw materials and water-jet pressure. For example, increasing water-jet pressure can enhance the product's strength and density; using cotton fiber raw materials can improve moisture absorption; adding polyester fibers can enhance wear resistance. This allows for customization of the plain spunlace non-woven fabric to meet the specific performance requirements of different industries.

High cost-effectiveness: The production process of plain spunlace non-woven fabric is relatively mature, does not require complex texture-forming equipment and processes, has high production efficiency (daily production capacity can reach tens of thousands of meters), and has a high raw material utilization rate (waste rate is less than 3%). Under the premise of ensuring product quality, production costs are effectively controlled. Compared with non-woven fabrics with special textures or complex functions, plain spunlace non-woven fabric offers higher cost-effectiveness and can meet the "low cost, high performance" procurement needs of downstream customers.
