Product Description

Changshu Yongdeli Spunlaced Nonwoven Fabric Co., Ltd. has been deeply engaged in the nonwoven fabric industry for many years. With continuous improvement in production technology and strict control over product quality, it has established a professional reputation in the spunlace nonwoven fabric sector. To further meet diverse market demands, the company, relying on its mature R&D system and production capacity, has launched chemical bond nonwoven fabric products with stable performance and diverse functions. Through scientific impregnation processes, these nonwoven fabrics acquire specialized functions and are widely applicable across various industry scenarios.

I. Production Process of Chemical Bond Nonwoven Fabrics

The core of producing chemical bond nonwoven fabrics is to fully integrate the base nonwoven fabric with the functional impregnation liquid. Changshu Yongdeli Spunlaced Nonwoven Fabric Co., Ltd. ensures each batch meets functional standards and maintains consistent quality through standardized production processes:

01
Selection and Pre-treatment of Base Materials: Suitable base nonwovens are selected (spunlace, thermal-bonded, or spunbonded) made of pure cotton, polyester, viscose, or blended fibers. Dust and impurities are eliminated via specialized cleaning equipment, followed by plasma treatment or mild chemical activation to optimize surface adhesion for subsequent liquid absorption.
02
Customization and Preparation of Impregnation Liquid: Technical formulations are developed based on functional needs (antibacterial, waterproof, oil-resistant, antistatic, flame-retardant). Utilizing eco-friendly water-based additives and stabilizers, parameters like concentration, viscosity, and pH are constantly monitored in real-time.
03
Impregnation Treatment: Materials enter the impregnation tank via unwinding units. Controlled speeds (3-15m/min) ensure thorough immersion, while pressure or multi-stage impregnation is applied for advanced technical specifications to guarantee deep, uniform fiber penetration.
04
Liquid Control Treatment: Adjustable precision rubber rollers (1-6MPa) regulate liquid pickup, eliminating waste and preventing excess hardening to preserve functional uniformity prior to curing.
05
Drying and Curing: Using infrared, hot air, or combined drying (70-140℃), solvents fully evaporate to establish stable functional bonding with the fibers. Moisture content is strictly retained within 5% for optimal material stability.
06
Post-treatment and Slitting: Softeners, thermal shaping, or embossing are applied based on customer requests. High-precision slitting units then convert the fabric into custom rolls or sheets.
07
Quality Inspection and Storage: Rigorous evaluations, including visual inspections, functional ratings (antibacterial rates, water resistance), and mechanical tests (tensile strength, elongation), verify total compliance before shipment.

II. Advantages of Chemical Bond Nonwovens

🎯
High Functional Customization

Formulas can be flexibly tailored to achieve single or multi-functional profiles—including antibacterial, waterproof, oil-resistant, antistatic, and flame-retardant characteristics tailored to medical or outdoor environments.

🛡️
Strong Functional Stability

Deep impregnation and chemical curing lock additives into fiber structures. Core functions remain stable even after 5 to 15 standard washes, providing exceptional durability and service life.

🔄
Broad Base Compatibility

Versatile processing works efficiently with spunlace, thermal-bond, and spunbond materials across natural, synthetic, or blended fibers without compromising functional efficacy.

⚡
High Production Efficiency

Integrated continuous lines deliver tens of thousands of square meters daily. In-line monitoring systems safeguard uniform consistency and zero batch-to-batch variation.

III. Characteristics of Chemical Bond Nonwovens

⚖️
Balanced Performance

Adds specialized functional attributes while preserving inherent fabric characteristics such as natural softness, breathability, and comfort.

🌱
Eco-Friendly Manufacturing

Complies with RoHS and REACH standards using water-based solvents and non-toxic additives, ensuring recyclability and natural degradability when using organic fibers.

📐
Superior Structural Uniformity

Precise tension, speed, and drying metrics prevent thickness variation or localized chemical deficiencies, ensuring a smooth, reliable fabric surface.

✂️
Excellent Processing Adaptability

Resists fraying and fiber shedding during high-speed converting. Exhibits high performance in cutting, sewing, heat-sealing, and adhesive lamination.
