Laminated Spunlace Fabric Products

Core advantages: Far superior to coating, with outstanding performance

As the core product of the company, laminated spunlace nonwoven fabrics rely on advanced composite technology and high-quality material combinations. Compared to traditional spunlace nonwoven fabrics, it has achieved multi-dimensional performance breakthroughs, with particularly prominent core advantages:

- Stronger bond between film and fabric, significantly improved durability: Using the PUR hot melt adhesive bonding process, the adhesive layer is uniform and has strong compatibility with the film and fabric materials. After curing, the bond strength of the film and fabric is far superior to that of the coating process, capable of withstanding repeated stretching, friction and water washing (for some material combinations), and is less likely to cause delamination or wrinkling. Traditional coating processes only use high-temperature to melt the film onto the fabric surface, resulting in a weaker bond and more frequent problems of film cracking and detachment over time, with durability far inferior to coated products.

- More diverse functional options, wider application scenarios: Flexible combination of different functional films and base materials to achieve multi-functional combinations such as waterproofing, breathability, elasticity, heat resistance, antibacterial, and anti-aging. For example, combining PTFE film can achieve "waterproof breathable", and combining TPU film can achieve "waterproof elasticity"; while coating processes mostly use a single PE film, which has limited waterproof functionality and cannot meet the multi-functional requirements of complex scenarios.

- Superior texture, suitable for high-end scenarios: The coated process can fully retain the soft texture of spunlace nonwoven fabric base materials, while the selection of film materials is diverse, such as PU film can give the product a leather-like texture, PET film can enhance the stiffness. Traditional coating processes often result in a stiff and rough texture due to the melting and attachment of the film material, making it difficult to meet the requirements of high-end scenarios.

- Better environmental performance, safer use: Using environmentally friendly PUR hot melt adhesive, without harmful solvent volatilization, and the adhesive layer dosage is precisely controllable, the product has no odor, no harmful residues; some films (such as TPU, PU) and base materials comply with environmental standards. While some coating processes may use volatile components as additives, and the film melting process may produce trace harmful substances, the environmental performance is slightly inferior.

Advanced production technology: Precise bonding, quality controllable

The outstanding quality of laminated spunlace nonwoven fabrics stems from the company's "base material refinement + precise bonding + full process quality control" refined production system. The production process is based on customized spunlace non-woven fabric substrates. The perfect adhesion of the film and the fabric is achieved through the PUR hot melt adhesive bonding process. The entire process is efficient and environmentally friendly. The key steps are as follows:

1. Customized substrate production: According to the functional requirements of the customers, substrates such as polyester, viscose, cotton, and bamboo fiber are selected and matched. Through processes such as sorting, loosening, mixing, combing, cross-laying, and high-pressure spunlace reinforcement, a specialized spunlace non-woven fabric substrate is produced. For different scenarios, the substrate weight, thickness, and performance can be adjusted to ensure that the substrate is compatible with the characteristics of the subsequent film.

2. Raw material pre-treatment: The spunlace non-woven fabric substrate is dried and shaped to remove excess moisture and calibrate the size, ensuring a smooth and wrinkle-free surface; according to the characteristics of the film assembly, the film is pre-treated (such as surface activation treatment) to enhance the adhesion of the adhesive layer, laying the foundation for the bonding process.

3. Core process of PUR hot melt adhesive bonding: Using a high-precision bonding machine, the environmentally friendly PUR hot melt adhesive is evenly coated on the surface of the spunlace non-woven fabric or the film, and then the film and the fabric are precisely bonded by the bonding roller. The equipment can precisely control the amount of adhesive, coating density, bonding temperature, and pressure to ensure a uniform adhesive layer and aligned film and fabric; after bonding, it enters the curing zone, where it is subjected to specific time and temperature curing to achieve the best bonding strength. This step is the core guarantee for the product to be superior to the laminating process.

4. Post-treatment and performance optimization: After bonding and curing, the product undergoes processes such as rolling, cutting, and trimming to optimize the surface texture and size accuracy; for specific requirements, additional post-treatment such as water washing resistance, UV resistance, etc. can be carried out to further enhance the product performance and expand the application scenarios.

5. Full-process quality control system: The substrate needs to be tested for weight, strength, and air permeability, etc.; during the bonding process, real-time monitoring of the adhesive amount, bonding temperature, and alignment of the film is carried out; the finished product needs to be tested for film peel strength, waterproofness, air permeability (if required), environmental indicators, etc., to ensure that each batch of products is superior to industry standards and has stable performance far exceeding traditional laminating products.
