Anti-Ultraviolet/Sunscreen Spunlace Nonwoven Fabric Products

I. Product Foundation: Core Characteristics and Advantages of Spunlace Nonwoven Fabric, Laying a Solid Foundation for Sun Protection Function

The practical value and experience of anti-ultraviolet/sunscreen spunlace nonwoven fabric stem from the excellent characteristics of spunlace nonwoven fabric itself. Our company selects polyester, viscose, pure cotton, and bamboo fiber as core raw materials, and uses mature spunlace technology to create base materials. These core characteristics not only provide support for the stable loading of anti-ultraviolet/sunscreen agents but also become the key advantages for product adaptation to multiple scenarios:

Flexible, skin-friendly, and non-restrictive, suitable for diverse scenarios: The spunlace process uses high-pressure water jets to entangle fibers, forming a mesh structure without the distinction of warp and weft directions. The base material is soft and highly extensible - viscose, pure cotton, and bamboo fiber base materials have a touch as fine as cotton, providing a comfortable skin contact without friction or discomfort, suitable for close-fitting scenarios such as outdoor T-shirts, sun protection masks, and children's sun protection clothing; polyester base materials have both flexibility and stiffness, meeting the requirements for shape stability in outdoor tents and sunshades. Different raw material ratios can achieve customized touch sensations of "soft but not wrinkled, tough but not hard", suitable for complex usage forms such as bending and folding, without worrying about the damage of sun protection function due to material deformation.

Highly breathable and moisture-absorbent, refusing stuffiness： Spunlace base material fibers have uniform gaps and a porous structure， with breathability far exceeding traditional sun protection fabrics - pure cotton and bamboo fiber base materials have a breathability of 1500-2200mm/s， and viscose base materials have a moisture absorption rate of ≥9g/10min， which can quickly conduct water vapor and sweat， avoiding the sticky and hot feeling caused by summer outdoor use (such as sun protection clothing and sports sleeves)； even polyester base materials have optimized breathability channels through fiber modification， and after loading anti-ultraviolet/sunscreen agents， they still maintain the advantage of "sun protection without sweating"， suitable for long-term outdoor exposure scenarios.

Strong， durable， and resistant to wear and tear， extending the sun protection life： The spunlace process tightly entangles fibers， and the base material's tensile strength is significantly better than that of ordinary nonwoven fabrics - polyester base material has a longitudinal tensile strength of ≥850N/m and a transverse tensile strength of ≥550N/m， and is not easily damaged by repeated stretching and friction， capable of withstanding wind and friction during outdoor use； pure cotton and bamboo fiber base materials， after scientific blending， can also withstand daily washing and outdoor use wear and tear， avoiding the decline in base material strength due to the loading of anti-ultraviolet/sunscreen agents； even after 20 washes， the base material can still maintain structural stability， and the sunscreen agents are not easily lost， extending the overall sun protection life of the product and reducing customer replacement costs.

Environmentally friendly， safe， and non-irritating， suitable for sensitive groups： The selected polyester， viscose， pure cotton， and bamboo fiber all meet the OEKO-TEX® Standard 100 environmental standards， free of formaldehyde and harmful heavy metals， and pure cotton and bamboo fiber are natural degradable materials； The spunlace process does not require the addition of adhesives, and the base material is odorless and non-irritating, ensuring safety from the source. It is suitable for children, people with sensitive skin, and other groups sensitive to materials, especially for children's sun protection clothing and outdoor products for mothers and babies.

Flexible customization and strong adaptability to meet individual needs: According to the customer's sun protection intensity and scene requirements, the proportion of raw materials can be flexibly adjusted - for a pursuit of skin-friendly and breathable, the proportion of viscose, pure cotton, and bamboo fiber can be increased (such as 50% pure cotton + 50% viscose); for a pursuit of durability, wear resistance, and high sun protection, the proportion of polyester can be increased (such as 75% polyester + 25% bamboo fiber); the basis weight (35-200g/㎡ adjustable), thickness, and density can all be customized. At the same time, it is compatible with the immersion and pressing method for sun protection processing to ensure that the characteristics of the base material and the sun protection function are perfectly matched, maximizing the dual value of sun protection and experience of the product.

II. Core Technology: Immersion and Pressing Method with Anti-Ultraviolet/Sun Protection Additives for High-Efficiency and Long-Lasting Sun Protection

Our anti-ultraviolet/sun protection spunlace non-woven fabric strictly follows the step-by-step process of "first making high-quality spunlace base material, then doing the anti-ultraviolet/sun protection additive finishing". According to the demand for sun protection level (UPF value) in different scenes, the immersion and pressing method is the core processing method. Through precise control, the anti-ultraviolet/sun protection additives are evenly attached and stably effective, without damaging the original characteristics of the spunlace base material:

Selection of sun protection additives: Safe and efficient, suitable for multiple scenes: Environmentally friendly anti-ultraviolet additives that meet national textile product safety standards (mainly benzotriazole and benzophenone) are selected. They are non-irritating and do not contain volatile harmful substances. They have passed skin irritation tests (no redness or itching reactions) and can be safely used in skin-contact scenes. The ultraviolet blocking rate of the additives is ≥99%, effectively absorbing or reflecting UVA (wavelength 320-400nm) and UVB (wavelength 280-320nm). After loading, the UPF value of the product can stably reach 50+ (the highest sun protection level in the national standard), meeting the sun protection needs of different scenes.

Immersion and pressing process: Full penetration, uniform sun protection without blind spots: The spunlace base material is completely immersed in the anti-ultraviolet/sun protection additive solution (concentration 1.5%-4% adjustable, customized according to the target UPF value), low-speed stirring (30-50r/min) ensures the uniform dispersion of the additives, the immersion time (20-30 seconds) is precisely controlled, allowing the additives to fully penetrate into the fiber interior (rather than just adhering to the surface), avoiding local sun protection insufficiency; then, it is precisely rolled dry by double rollers (pressure 0.4-0.7MPa, liquid retention 70%-90%), removing excess solution; finally, it is cured by low-temperature hot air (85-100℃), forming a stable combination with the fibers. After 20 washes, the product's UPF value still remains above 40+, with the full-width sun protection distribution error ≤5%, achieving "full-area, long-lasting" sun protection.

Base material adaptation optimization: Process fine-tuning, retaining core advantages: Adjusting processing parameters according to the characteristics of different base materials - for highly absorbent base materials such as pure cotton, viscose, and bamboo fiber, low-concentration additive solution immersion and pressing + short-time low-temperature curing are used to avoid the base material becoming hard and affecting the skin-friendly feel; for hydrophobic polyester base materials, plasma surface treatment is performed before immersion and pressing to enhance adsorption, ensuring the uniform attachment of the additives; ultimately achieving the effect of "loading sun protection function without sacrificing the basic experience of the base material", making the product both sun-protective and comfortable.

III. Unique Product Features: Sun Protection Function + Base Material Advantage Overlap, Creating Core Competitiveness

Relying on high-quality spunlace base materials and precise sun protection processing technology, our anti-ultraviolet/sun protection spunlace non-woven fabric has the unique advantage of "base material characteristics + sun protection function" dual overlap, differentiating from traditional sun protection materials and better meeting the needs of diversified scenes. High-efficiency and broad-spectrum sun protection, blocking all wavelengths of ultraviolet rays: The product's UPF value stably reaches 50+, with a UVA blocking rate of ≥98% and a UVB blocking rate of ≥99%. It can comprehensively protect against harmful ultraviolet rays during outdoor exposure, preventing sunburn, tanning, skin aging, and even reducing the long-term damage of ultraviolet rays to the skin. It is suitable for high-altitude areas, beaches, summer outdoor activities, and other scenarios with strong ultraviolet radiation.

Long-lasting and stable sun protection, washable and durable: Through the immersion method, the sun protection agents penetrate the interior of the fibers and stably combine. After 20 washes, the UPF value still remains at 40+, and after 300 hours of outdoor exposure, the sun protection performance decline is ≤10%. There is no need to frequently replace the product, which not only reduces the usage cost but also reduces the environmental pressure caused by discarded materials. It is suitable for outdoor equipment and home sun protection products that need long-term use.

Balancing sun protection and user experience, no usage drawbacks: Unlike traditional sun protection fabrics that prioritize sun protection over user experience, this product retains the flexibility, breathability, and skin-friendliness of spunlace non-woven fabric after loading the sun protection function - it feels soft and flexible when in contact with the skin, does not cause discomfort even after long-term wear, and there is no cracking of the sun protection layer when bent or folded. Even in high-temperature outdoor environments above 35℃, it maintains good breathability and moisture absorption, avoiding the embarrassment of "sweating due to sun protection", achieving a seamless integration of "high-efficiency sun protection and comfortable experience".

Safe, environmentally friendly, and compliant, suitable for all people: The sun protection agents are non-irritating and have no harmful residues, meeting national textile product safety standards. They have passed the skin irritation test for children and are suitable for use by children, pregnant women, and people with sensitive skin. The base material is made of environmentally friendly fibers, and some materials (such as 100% cotton and bamboo fiber) are biodegradable, in line with the trend of green consumption, and suitable for brands and users who pay attention to environmental protection.
