🧵Diverse High-Quality Raw Materials, Bearing the Foundation of Customized Functions

The stability of the efficacy and applicable scenarios of functional additive spunlace nonwoven fabric begins with the scientific selection of high-quality raw materials. Yongdeli adheres to the core principle of "matching function and function with base materials + matching requirements with scenarios", carefully selecting high-quality raw materials such as polyester, viscose, cotton, and bamboo fiber to produce spunlace base fabric. Each raw material, with its unique fiber structure and characteristics, provides an efficient loading carrier for functional additives and also takes into account the usage requirements of multiple scenarios:

⚙️Polyester

The fiber structure is stable and resistant to wear and chemical corrosion, and is highly compatible with functional additives such as flame retart and anti-static. After loading, the efficacy is long-lasting and does not fade, suitable for industrial and outdoor high-frequency usage scenarios.

💧Viscose

It has excellent moisture absorption and fiber structure, with a loading rate of functional additives up to 5-8 times of its own weight. It can quickly and evenly absorb functional additives and stably adhere, improving the uniformity of functional efficacy.

🌱Cotton

It is naturally skin-friendly and non-irritating, with soft and fine fibers. It has excellent compatibility with antibacterial and skin-friendly functional additives, with excellent safety performance, suitable for medical, mother and baby, and close-fitting clothing scenarios.

🎋Bamboo Fiber

It has a natural mild antibacterial property, and when combined with functional additives, it can form a "basic function + enhanced efficacy" composite advantage. The porous structure of the fiber facilitates the adsorption of functional additives, achieving long-term functional maintenance.

✨Core Characteristics, Advantages and Mainstream Functional Additives

Yongdeli functional finishing spunlace nonwoven fabric relies on high-quality raw materials, neutral additives guarantee, and advanced impregnation process to form multiple advantages. At the same time, it provides a wide range of functional additive options to meet the customized needs of different industries:

Core Guarantee of Neutral Additives: All functional additives are strictly controlled within the pH range of 7.0 ± 0.5, avoiding corrosion of the drying barrel equipment by acidic or alkaline additives, and ensuring that the product is non-irritating, suitable for scenarios with high safety requirements such as skin contact and food-related.

Main Functional Additives Types:

🛡️Antibacterial

Divided into natural plant extract type (such as honeysuckle extract, bamboo vinegar solution) and safe synthetic type (such as quaternary ammonium salts), with an antibacterial rate of over 99%, suitable for medical, mother and baby, and other scenarios that require high safety standards, effectively inhibiting common bacteria such as Escherichia coli and Staphylococcus aureus.

☔Waterproof

Using fluorocarbon and non-fluorocarbon environmentally friendly waterproof additives, forming a breathable waterproof membrane layer, with waterproof grades up to IPX4-IPX6, suitable for outdoor clothing, home waterproof fabric, medical protection, etc., with both waterproof and breathable performance.

⚡Anti-Static

Including cationic and non-cationic anti-static additives, with the surface resistance stable at 10⁶-10⁹Ω, suitable for electronic workshops, packaging of precision instruments, industrial dust-proof clothing, etc., avoiding static adsorption of dust or breakdown of electronic components.

🔥Flame-Retart

Select halogen-free environmentally friendly flame-retarts with a flame-retart grade up to GB 8965.1-2023 B1 level. They are suitable for industrial protection, public facility decoration, outdoor tents, etc. They do not spread when exposed to fire and extinguish on their own when away from the fire.

🧪Other Customized Additives

According to requirements, develop anti-mite additives (with an anti-mite rate of ≥90%), moisture-absorbing and sweat-discharging additives (with an increase in moisture absorption rate of 50%), and anti-ultraviolet additives (with an UPF value of ≥50+). They meet the functional requirements of special scenarios.

Core Product Advantages:

1. Dual Services of Customization and Incoming Material Processing: Support full customization of additives, and also accept incoming material processing (only neutral additives are accepted). Adapt to customers' own formulations, and can flexibly undertake small batch trial production to large-scale mass production.
2. Uniform Loading and Long-Lasting Efficacy: The wetting and dyeing process enables the additives to evenly penetrate the fibers. The roller pressure is precisely controlled (0.2-0.5 MPa). After 20 washes, the function retention rate still reaches over 80%, far exceeding the industry average.
3. Safe, Environmentally Friendly and Compliant: Additives are all selected from environmentally friendly raw materials, without formaldehyde or heavy metals. They pass skin irritation level 0 test and food contact grade testing, suitable for all strict scenarios.
4. Excellent Processing Performance: Retain the softness and toughness of the spunlace fabric, with a tensile strength of over 10N. It can be folded, cut, sewn, printed, etc. Neutral additives do not change the original color and feel of the substrate, and are suitable for subsequent processing.
5. Precise Substrate Matching: Match the optimal substrate according to the type of additives (such as cotton/cellulose fiber for antibacterial, polyester for flame retarcy). Maximize the synergy of functional efficacy and substrate characteristics.

🔄Core Process of Wetting and Dyeing with Neutral Additives

Yongdeli has established a full-process standardized production system of "substrate selection - spunlace forming - additives control - wetting and loading - drying and fixation - precise detection", to ensure the safety of equipment and the quality of efficacy. The process is as follows:

1
Substrate Selection and Spunlace Forming: Select appropriate substrates according to the customer's functional requirements (such as polyester for waterproofing, cotton for antibacterial). After sorting, screening, loosening, and combing, high-pressure spunlacing is used to solidify the fabric into a flat and uniform spunlace base fabric, ensuring that the substrate has good adsorption properties.
2
Neutral Additives Control (Core Safety Step): When customizing additives, the formula is prepared and then precisely tested with a pH meter to be within the 7.0 ± 0.5 neutral range; when receiving incoming materials, the pH value and component compatibility are first tested, and non-neutral or failed incoming materials are returned from the source to protect the drying barrel.
3
Wetting and Loading (Core Efficacy Step): On the finishing line, the base fabric is immersed in neutral additive liquid, fully soaked for 3-5 seconds, and then the liquid amount is controlled by adjustable rollers (20%-40%) to ensure the uniform attachment of the additives to the fiber surface and interior.
4
Drying and Fixation: Use a temperature gradient of 80°C - 180°C for drying to avoid damage to the efficacy of the additives by high temperature. Neutral additives have no corrosive risk. After drying, the additives are firmly combined with the fibers.
5
Post-Processing and Testing: Cut into 20 - 200g/㎡ weight, 1 - 3.2m width finished products as required. Undergo "function-specific testing (such as antibacterial rate, flame retart grade) + safety testing (pH value, heavy metals) + physical testing (stability, strength)" triple inspections, with a 100% pass rate for factory release.
