Diverse high-quality base fabric materials, laying a solid foundation for the light-changing effect
The quality and effect of the photosensitive color-changing spunlace nonwoven fabric first depend on the selection of the base fabric material. Yongdeli adheres to the principle of "high-quality base material + precise matching", and selects high-quality raw materials such as polyester, viscose, Tencel, silk, bamboo fiber, and pure cotton to make spunlace base fabrics. According to the requirements of the light-changing effect and the characteristics of the usage scenarios, targeted matching can be carried out.
The advantages of each base material and the photosensitive color-changing technology form a perfect complement:
The flexible choice of multiple base materials enables Yongdeli's photosensitive color-changing spunlace nonwoven fabric to not only meet the usage requirements of different scenarios but also provide a stable carrier for the photosensitive color-changing powder, ensuring the long-lasting and stable light-changing effect.
- Polyester: It has excellent strength and weather resistance. The base fabric made from it has high flatness and is not prone to deformation, which can stably carry the photosensitive color-changing coating and is suitable for outdoor and high-frequency usage scenarios.
- Viscose/Tencel/Silk: All three have excellent skin-friendliness and breathability. Tencel and silk also have a delicate texture. The photosensitive color-changing nonwoven fabric made from them is suitable for scenarios close to the skin, such as clothing and home textiles.
- Bamboo fiber/Pure cotton: They are natural and environmentally friendly and have good moisture absorption. Bamboo fiber also has a mild antibacterial property. After combining with the photosensitive color-changing effect, they are suitable for fields with high safety requirements, such as baby products and cultural and creative gifts.
Core characteristic advantages, unlocking creative application possibilities
Yongdeli's photosensitive color-changing spunlace nonwoven fabric breaks the limitation of traditional nonwoven fabric's "fixed color" and integrates the basic advantages of spunlace technology with the creative characteristics of photosensitive color-changing, forming four core competitive advantages:
1. Precise light-sensing trigger, smooth color change: The product is equipped with high-quality photosensitive color-changing powder and can be customized to achieve "specific light trigger" effects according to customer needs. Whether it is ultraviolet light (such as sunlight), visible light, or specific wavelength light, it can precisely respond and achieve color conversion. The color-changing process is smooth and natural, with a uniform transition from the initial color to the changed color, and high color saturation, providing a distinct visual effect.
2. Triple post-treatment processes, diverse light-changing forms: It innovatively adopts three post-treatment processes: drop coating, printing, and scraping, which can present different light-changing forms according to creative needs - point distribution, flower patterns, or full coverage, meeting the diverse design requirements from local embellishment to overall color change, and endowing the product with stronger creative plasticity.
3. Stable light-changing performance, excellent durability: It uses imported photosensitive color-changing powder with strong fatigue resistance. After repeated light-changing tests, it can achieve more than 10,000 cycles of color change while maintaining a stable light-changing effect. At the same time, through special fixation process treatment, the color-changing layer is closely combined with the base fabric, and it is resistant to water washing (no shedding after 20 washes at 30°C water temperature) and friction, suitable for daily usage scenarios.
4. Full-chain customization to meet diverse demands: Supports full-dimensional customization of "light-changing parameters + base material + process" - customizable light-changing colors (such as colorless to red, yellow to orange, etc.), customizable trigger light (such as UV-specific trigger, visible light universal trigger), customizable base material, and customizable process form, truly achieving "customized on demand, exclusive creativity".
Innovative production process, controlling the core quality of light-changing
Yongdeli has established a full-process production system of "base material preparation + post-treatment processing + precise detection", especially forming a core technical advantage in the post-treatment processing link. Through three customized processes, it achieves the perfect integration of light-changing powder and spunlace base material:
1. Step 1: Preparation of high-quality spunlace base material: Select the corresponding base material according to customer needs, and after pre-treatment such as sorting, decontamination, opening, and mixing, form a uniform fiber web through a high-speed precision carding machine. Then, through multiple high-pressure spunlace consolidation processes, the fibers are entangled to make a spunlace non-woven base material with uniform texture, strength meeting standards, and a smooth surface. After drying and setting, the surface is cleaned to ensure no impurities affect the adhesion of the light-changing layer.
2. Step 2: Customized post-treatment processing (core link): According to customer creative needs, select the corresponding processing technology and precisely integrate the light-changing powder:
- Drip molding process: Mix the light-changing powder with PVA slurry in a precise proportion and stir evenly. Through an automated drip molding machine, the mixed slurry is dripped onto the base material surface in a preset dot pattern, with customizable dot size and spacing. After low-temperature drying and curing, a raised dot-shaped light-changing area is formed, giving a three-dimensional texture when touched.
- Printing process: Fully blend the light-changing powder with special printing slurry, and use screen printing or digital printing technology to print the mixed slurry onto the base material according to the designed pattern, achieving complex patterns and gradient effects in light-changing. After constant-temperature drying, the pattern is clear and the color is uniform, and the entire pattern changes color when the light-changing is triggered.
- Scraping process: Mix the light-changing powder with a compatible slurry to form a uniform coating liquid. Through a adjustable scraper device, the coating liquid is evenly scraped onto the base material surface, with the coating thickness precisely controlled (5-30μm). After high-temperature curing, a flat light-changing coating is formed, achieving a full-area light-changing effect on the base material.
3. Step 3: Special light-changing performance detection: Establish a "triple detection standard" to ensure quality - light-changing effect detection (test the color-changing response speed and color consistency under different light conditions), adhesion strength detection (wash and friction tests to verify the adhesion of the light-changing layer), and base material performance detection (re-inspection of basic indicators such as strength and breathability), ensuring that each batch of products meets the customization requirements.
