Far-Infrared Negative Lon Nonwoven Fabric Products

1. Product Foundation: Core Characteristics and Advantages of Nonwoven Fabric, Laying the Foundation for Function Upgrade

The outstanding experience of far-infrared negative ion nonwoven fabric begins with the excellent characteristics of nonwoven fabric itself. Our company selects polyester, viscose, cotton, and bamboo fiber as core raw materials, and through mature nonwoven fabric processing to create the substrate. The core characteristics and advantages of the substrate provide a solid foundation for subsequent function loading, and also become an important basis for the differentiated experience of the product:

Extremely flexible and skin-friendly, suitable for scene requirements: The nonwoven fabric process uses high-pressure water flow to make fibers interlock, forming a mesh structure without longitudinal and transverse differences. The substrate texture is soft and has strong extensibility - viscose, cotton, and bamboo fiber substrates have a delicate touch like cotton, with no friction discomfort when used on intimate scenarios such as underwear and care pads; polyester substrates also have both flexibility and firmness, can meet the requirements for form stability in outdoor wear and home upholstery, and different material ratios can achieve "soft without collapse, tough without hardness" customized texture.

Efficient ventilation and moisture absorption, saying goodbye to stuffiness and humidity: The fiber gaps of the nonwoven fabric substrate are uniform and have a porous structure, with ventilation performance far exceeding that of traditional nonwoven fabrics - the ventilation rate of cotton and bamboo fiber substrates can reach 1500-2000mm/s, the moisture absorption rate of viscose substrates is ≥8g/10min, which can quickly conduct water vapor and sweat, avoiding the feeling of stuffiness and stickiness caused by prolonged use; even polyester substrates, through fiber modification and process optimization, achieve a balance between ventilation and washability, suitable for sweaty outdoor activities and night care scenarios.

Strong and durable, extending product lifespan: The nonwoven fabric process makes the fibers closely intertwined, the breaking strength of the substrate is significantly better than other types of nonwoven fabrics - polyester substrates have a longitudinal breaking strength of ≥800N/m and a transverse strength of ≥500N/m, and are not prone to damage after repeated stretching and friction; after optimization of the ratio of cotton, bamboo fiber, the polyester and bamboo fiber substrates can also meet the needs of daily washing and use, avoiding the loss of substrate strength caused by function loading, ensuring that the product maintains stable performance for a long time and reduces customer replacement costs.

Environmentally friendly and safe compliance, suitable for diverse populations: The polyester, viscose, cotton, and bamboo fibers selected all meet the OEKO-TEX® Standard 100 environmental standards, without formaldehyde or harmful heavy metals, cotton and bamboo fibers are even natural biodegradable materials; the nonwoven fabric process does not use adhesives, the substrate has no odor or irritation, ensuring product safety from the source, suitable for scenarios with strict material safety requirements such as mothers, sensitive skin, and the elderly.

Flexible substrate customization, adapting to functional needs: The raw material ratio can be adjusted according to the customer's functional emphasis - pursuing moisture absorption and skin-friendly, increase the proportion of viscose, cotton, and bamboo fibers (such as 60% cotton + 40% viscose); pursuing durability and washability, increase the proportion of polyester (such as 70% polyester + 30% bamboo fiber); Each batch of base material can be customized in terms of weight (30-200g/㎡ adjustable), thickness, and density, ensuring a perfect match between the base material properties and the far-infrared negative ion function, maximizing the product value.

II. Core Process: Loading far-infrared negative ion agents through immersion and soaking to achieve precise function implementation

Our far-infrared negative ion spunlace non-woven fabric strictly follows the step-by-step process mode of "first manufacturing high-quality spunlace base material, then adding functional additives through immersion and soaking". According to different base material characteristics and functional requirements, the immersion and soaking method is used as the core processing method. Through meticulous control, the far-infrared negative ion agents are evenly penetrated and stably attached, allowing the function to deeply integrate with the base material properties:

Additive selection: Safe and efficient, in line with health positioning: Select far-infrared negative ion composite agents that comply with national food and drug standards - the far-infrared components are mainly composed of nano-sized zirconium dioxide and magnesium oxide, with a far-infrared emission rate of ≥88% (wavelength 8-14μm, matching the human far-infrared wavelength and easily absorbed); the negative ion components use natural tourmaline powder and nano titanium dioxide in combination, with a negative ion release rate of ≥1500 per cm³, and no radioactivity or irritation, ensuring the function is exerted while not affecting the environmental safety characteristics of the base material.

Immersion process: Full penetration, uniform function without dead corners: The immersion process through "immersion - drying - curing" three steps realizes the deep combination of additives and base material - fully immerse the spunlace base material in the far-infrared negative ion agent solution (concentration adjustable from 1% to 3%, customized according to functional requirements), low-speed stirring (40-60r/min) ensures the uniform dispersion of additives, precise control of immersion time (15-25 seconds), allowing the agents to fully penetrate the fibers inside (rather than only adhering to the surface); then through double-roller precise drying (pressure 0.3-0.6MPa, liquid content 65%-85%), removing excess solution to avoid uneven function; finally, through low-temperature hot air curing (80-95℃), the agents form a stable chemical bond with the fibers, after 10 water washes, the far-infrared emission rate attenuation ≤5%, negative ion release rate attenuation ≤10%, ensuring the function is stable and lasting.

Base material adaptation: Process fine-tuning, retaining core characteristics: Optimize immersion parameters for different base material characteristics - for moisture-absorbing cotton, viscose, and bamboo fiber base materials, reduce additive concentration and shorten curing time to avoid the base material hardening and affecting the skin feel; for hydrophobic polyester base materials, first perform plasma surface treatment to enhance adsorption force, ensuring the uniform attachment of additives, while not damaging its washable and durable characteristics, ultimately achieving the effect of "function loading without sacrificing the basic experience".

III. Unique Product Features: Dual empowerment of far-infrared + negative ions, creating health value

Relying on high-quality spunlace base material and precise immersion process, our far-infrared negative ion spunlace non-woven fabric has the unique advantage of "base material properties + dual functions", becoming the core competitiveness different from ordinary functional non-woven fabrics:

Far-infrared function: Warmth and health preservation, suitable for multiple temperature scenarios: The product can absorb environmental heat or body heat, converting it into 8-14μm far-infrared rays (consistent with the "life light wave" wavelength of the human body), after being absorbed by the human body, it can promote local blood circulation and relieve muscle fatigue - when used in winter (such as thermal underwear, waist protectors), it can increase body surface temperature by 2-3℃, reducing cold stimulation; in medical auxiliary scenarios (such as postoperative care pads), it can assist in improving local microcirculation, accelerating wound healing, and the far-infrared emission has no dead corners, all contact areas can enjoy the function effect. Negative ion function: Purify and inhibit bacteria, safeguard a healthy environment: The product continuously releases negative ions (release volume ≥ 1500 per cm³, equivalent to the level of the edge of a forest), which can adsorb dust and odor molecules (such as formaldehyde, unpleasant odors) in the air, and inhibit bacterial growth - in indoor scenarios (such as curtains, sofa covers), it can assist in air purification and reduce dust adhesion; in close-contact scenarios (such as underwear, baby clothes), the antibacterial rate against Escherichia coli and Staphylococcus aureus is ≥ 90%, reducing skin discomfort caused by bacteria; negative ions are non-irritating, and can be safely used by mothers, infants, and sensitive skin individuals.

Balancing function and experience: Without sacrificing basic attributes: Different from the problem of traditional functional materials "emphasizing function but neglecting experience", after loading the far-infrared negative ion function, this product still fully retains the flexible, breathable, and skin-friendly characteristics of the spunlace non-woven fabric - when used against the skin, there is no stiffness, and it is not hot after wearing for a long time, and the function and strength remain stable after repeated washing, achieving "seamless integration of healthy functions and daily experience".

Safe and long-lasting: No side effects, suitable for long-term use: The far-infrared negative ion agent has no radioactivity, no chemical irritation, has undergone skin irritation tests (no redness, itching reactions), and heavy metal detection (lead, mercury ≤ 0.1mg/kg), meeting the safety standards for mothers and medical grade; the function is stable and persistent, in daily usage scenarios (such as home fabrics, underwear), the function validity period can reach 2-3 years, no need to frequently replace, which not only reduces usage costs but also reduces environmental pressure.
