Color Absorption Nonwoven Fabric Product Manual

I. Core Advantages of Color Absorption Nonwoven Fabrics: Performance Breakthrough in Stain Prevention Scenarios

Color-absorbing nonwoven fabrics retain the natural advantages of viscose fibers and achieve "targeted capture" of dye molecules through functional upgrades. Their core advantages precisely adapt to the strict requirements of laundry stain prevention, far exceeding that of ordinary nonwoven fabrics:

1. Leading dye absorption efficiency, more thorough stain prevention

Ultra-fast capture of free dyes: Using cationic modified viscose fibers, based on the principle of positive and negative ion adsorption, it quickly combines with the anionic type dyes (such as those commonly used in cotton fabrics for reactive dyes) through the adsorption response time of less than 30 seconds, which is 3 times higher than that of ordinary viscose nonwoven fabrics.

Absorption capacity far exceeds conventional materials: The multi-porous mesh structure formed through special spunlace process, with fiber gaps 40% higher than ordinary spunlace fabrics, and the loose structure similar to activated carbon can simultaneously adsorb cationic dyes. The maximum adsorption capacity of a single gram material can reach 80% of its own weight, and 1 piece of 15g product can handle 5kg of laundry detergent-generated free dyes.

2. Stable and long-lasting color retention, zero risk of secondary pollution

Strong locking and no re-bleeding: The adsorption groups on the modified fiber surface form stable chemical bonds with dye molecules. After 30 minutes of strong washing and stirring in the washing machine, the dye shedding rate is less than 1%, completely avoiding the "re-release after adsorption" problem that leads to secondary staining.

High compatibility with detergents: In neutral and weakly alkaline washing agent environments (pH value 6-10), the color absorption performance remains above 95%, and it will not be affected by the detergent components, suitable for various household laundry detergents and laundry powders usage scenarios.

3. Physical properties adapted to washing scenarios, more reliable usage experience

Water-resistant and not prone to damage: Using multiple cross-spunlace processes, the fiber entanglement strength is increased by 50%, the longitudinal breaking strength is ≥ 12N/5cm, and the transverse breaking strength is ≥ 8N/5cm. After repeated stirring in the washing machine, there is no tearing, fraying, or clumping phenomenon, meeting the structural stability requirements for one-time use.

Uniform web formation and color absorption: The imported combing equipment ensures that the fiber distribution error is ≤ 2%, and the fabric surface has no local density differences, avoiding color absorption imbalance and resulting in blind areas of protection. Each area of mixed light and dark clothing can receive uniform protection.

4. Natural base material safe and environmentally friendly, suitable for healthy consumption demands

Raw materials without irritation and zero harm: 100% high-quality viscose fibers come from natural plant resources, without fluorescent agents, formaldehyde, or harmful chemical modifications. The skin irritation test shows no allergic reaction, and there is no safety hazard when in direct contact with the clothing.

Disposal and degradation without burden: After disposal, the product can completely degrade in 3-6 months in the natural environment, without plastic residue pollution, conforming to the current green laundry consumption trend.

5. Excellent processing adaptability and higher downstream production efficiency

Zero loss in cutting and stamping: The fabric surface is flat and has moderate toughness. When processed into 10cm×15cm standard pieces by automated stamping equipment, the edges have no frayed edges and the fibers do not fall off, with a product rate of 99.5% or more. Highly compatible functional properties: It can directly combine antibacterial and mite-repellent functional additives (such as silver ion modification), and has been tested to have an antibacterial rate of over 99% against Staphylococcus aureus and Escherichia coli, without affecting the core color-absorbing performance, meeting the requirements for the development of multi-effect anti-collusion color products.

II. Core features of the color-absorbing spunlace non-woven fabric: A precise balance of function and practicality

The color-absorbing spunlace non-woven fabric is centered on the "color-absorbing function" and based on practical performance, forming three core characteristics that differentiate it from others and become the preferred material for anti-collusion color products:

1. Function targeting: Specialized design for laundry scenarios

For common fabric fading problems in household washing such as cotton, linen, and polyester, by adjusting the fiber modification degree and pore structure, it can achieve full coverage adsorption of mainstream dyes such as reactive dyes and disperse dyes, especially suitable for protecting red, blue, black, and other easily fading clothes.

The white base can directly present the color-absorbing effect, allowing consumers to clearly perceive the dye capture process, solving the trust pain point of "unseen effect" in anti-collusion color products.

2. Performance stability: Reliable performance under extreme conditions

The temperature range is adapted to the entire household washing scenario, with no attenuation of color-absorbing performance within the 0-60℃ water temperature range. Even when dealing with high-temperature washing procedures (such as 60℃ washing for cotton fabrics), it can still maintain stable adsorption capacity.

The wet strength retention rate is over 85%, and it will not become loose due to water absorption expansion in high-water-level washing environments, ensuring the complete protection throughout the process.

3. Cost economy: Cost advantage in mass production scenarios

Using viscose fibers as the base material, compared to polyester-based color-absorbing materials, the raw material cost is reduced by 20%, and the functional modification process is mature and controllable. Under mass production conditions, the unit color-absorbing cost is only 60% of imported materials.

No additional adsorption carriers (such as activated carbon particles) are needed, avoiding dust pollution problems in downstream production, and reducing the difficulty and loss cost of product processing.

III. Main application fields of the color-absorbing viscose spunlace non-woven fabric: Full coverage of anti-collusion color products in all scenarios

Relying on efficient color absorption and stable performance, the color-absorbing viscose spunlace non-woven fabric has become the core base material for laundry anti-collusion color products, widely used in various scenarios such as household and commercial use, solving the industry pain point of deep and light-colored clothes mixed washing:

1. Core base material for household anti-collusion color products

Main one-piece anti-collusion color products: As the core layer of single-piece independent packaging anti-collusion color products, suitable for household daily washing scenarios, with a dosage of 1 piece / 5kg of clothes, it can achieve safe mixed washing of deep and light-colored clothes and colored and white clothes, helping consumers save time and water resources for separate washing.

Composite layer of multi-effect washing products: Combined with the washing function layer to form "color-absorbing + cleaning" two-in-one washing products, the color-absorbing base layer can simultaneously capture the dye molecules released during the washing process, avoiding secondary color collimation during cleaning.

Travel portable anti-collusion towel: Made into small-sized portable color-absorbing towels, suitable for small amounts of clothing mixed washing during trips and travels, each piece can handle 1-2 pieces of clothes, with a small size and easy to store.

2. Anti-collusion color materials for commercial washing

Hotel linen special color-absorbing fabric: For large-scale mixed washing scenarios of hotel bed sheets and towels, made into large size (1m×0.5m) color-absorbing fabric, each piece can handle 20kg of linen washing, efficiently solving the color collimation problem of different color linen washing, reducing linen loss rate.

Dry cleaning shop anti-collusion padding: Cut into custom-sized padding, placed in the dry cleaning machine to separate different color clothes, through adsorption of a small amount of dissolved dyes during dry cleaning, protecting high-end clothes from color collimation.

3. Extended application of functional washing accessories Fluorescent agent adsorption sheet substrate: Utilizing the porous structure to simultaneously adsorb free fluorescent agents in water, a "color absorption + fluorescent agent removal" dual-functional sheet is produced, suitable for washing scenarios with high safety requirements such as maternity clothing and underwear.

Antibacterial and anti-color transfer composite sheet: Through fiber antibacterial modification, a composite sheet with the functions of color absorption, antibacterial, and mite repellent is made. After testing, the repellency rate against dust mites is over 99%, suitable for use in maternal and infant families and sensitive populations.
