China Far-Infrared Negative Lon Nonwoven Fabric Products Suppliers, Factory
Product Description
1. Product Foundation: Core Characteristics and Advantages of Nonwoven Fabric
The outstanding experience of far-infrared negative ion nonwoven fabric begins with the excellent characteristics of the base material itself. We select polyester, viscose, cotton, and bamboo fiber as core raw materials, processing them into high-performance substrates via mature spunlace technology:
High-pressure water flow interlocks fibers into an isotropic web. Viscose, cotton, and bamboo fibers provide a silky, irritation-free touch suitable for intimate apparel, while polyester offers customizable, collapse-resistant texture.
The porous microstructure prevents stuffiness. Cotton/bamboo fiber airflow reaches 1500–2000 mm/s, and viscose maintains a moisture absorption rate of ≥8g/10min, quickly dissipating sweat and humidity.
Intertwined fibers deliver superior mechanical resistance. Polyester substrates exhibit longitudinal breaking strength ≥800N/m and transverse strength ≥500N/m, enduring repeated washing without compromising function.
All raw fibers comply with OEKO-TEX® Standard 100, free from formaldehyde and heavy metals. Produced without chemical adhesives, the fabrics are non-irritating, odorless, and safe for infants and sensitive skin.
Customizable blends (e.g., 60% cotton + 40% viscose for softness, or 70% polyester + 30% bamboo fiber for resilience) with weights adjustable from 30g/㎡ to 200g/㎡ to fit precise functional requirements.
II. Core Process: Loading Far-Infrared Negative Ions via Precision Immersion
Our production implements a strict step-by-step protocol: manufacturing premium spunlace base material first, followed by controlled immersion and soaking to infuse functional properties deep within the fibers.
We utilize certified composite additives. The far-infrared component relies on nano zirconium dioxide and magnesium oxide (88%+ emission rate, 8–14μm wavelength matching human bio-waves). The negative ion component combines natural tourmaline and nano titanium dioxide (≥1500 pcs/cm³ release), completely non-radioactive and non-irritating.
The fabric undergoes thorough immersion with low-speed stirring (40–60 r/min) for 15–25 seconds to penetrate fiber interiors. Precise double-roller dehydration controls liquid pick-up (65%–85%), followed by hot-air curing (80–95℃) to chemically bind additives. After 10 washings, performance attenuation remains exceptionally low (far-infrared ≤5%, negative ions ≤10%).
Immersion formulas adapt to fiber chemistry: natural moisture-absorbing fibers receive adjusted curing to maintain softness, while synthetic polyester undergoes plasma surface activation to enhance adhesion without altering physical comfort.
III. Unique Product Features: Dual Empowerment of Far-Infrared + Negative Ions
Converts body and environmental heat into 8–14μm infrared waves to improve microcirculation and ease muscle fatigue. Provides a 2–3℃ surface temperature rise in winter clothing and aids recovery in healthcare wraps without dead angles.
Continuous release of ≥1500 ions/cm³ breaks down ambient odors, neutralizes dust, and delivers a ≥90% antibacterial rate against E. coli and Staphylococcus aureus, ensuring a skin-friendly, sanitary environment.
Avoids the stiffness commonly seen in treated fabrics. Softness, drape, breathability, and physical strength remain intact, ensuring prolonged skin-contact comfort without stuffiness.
Passed skin sensitization and heavy metal testing (Pb, Hg ≤ 0.1mg/kg). Safe for maternal and medical applications, with an active functional lifespan reaching 2–3 years under daily use.
IV. Core Application Fields: Empowering Healthier Living
Optimal for thermal underwear, therapeutic waist belts, knee sleeves, and baby diaper surfaces. Keeps vulnerable joints warm while reducing the incidence of diaper rash through active antibacterial protection.
Integrated into blackout curtains, sofa upholstery, mattress covers, and bedding. Purifies home indoor air by settling dust particles and decomposing residual odors, ideal for renovated spaces.
Applied in technical jacket linings, sleeping bags, and thermal gear. Converts ambient energy to lock in body warmth in cold outdoor conditions while breathing out perspiration moisture.
Utilized in rehabilitation therapy wraps, post-surgery support pads, and clinical dressings. Assists local wound microcirculation and mitigates secondary cross-contamination risks.
V. Brand Commitment: Quality & Win-Win Partnerships
Changshu Yongdeli Spunlaced Nonwoven Fabric Co., Ltd. embeds "Sustainable Quality" into every step of development:
- Raw Material Traceability: Strict intake screening for fibers and mineral additives, backed by batch-level verification reports for emission and negative ion purity.
- Advanced Process Monitoring: In-line inspection utilizing air permeability meters, far-infrared spectrometers, and negative ion counters to ensure uniform coating.
- Full-Cycle OEM/ODM Support: End-to-end client consultation covering weight configuration, structural blending, functional testing, and ongoing after-sales quality tracking.
We utilize a proprietary precision immersion, padding, and low-temperature curing process. Rather than merely spraying the surface, the non-toxic nano mineral additives penetrate deep into the fibers, forming strong chemical bonds that preserve the natural softness of the spunlace web.
No. Thanks to our advanced curing and cross-linking technology, our fabric undergoes rigorous wash testing. After 10 consecutive washes, the far-infrared emission attenuation is less than 5%, and the negative ion release attenuation remains under 10%, ensuring long-term durability.
Yes. All base fibers meet the OEKO-TEX® Standard 100 criteria without formaldehyde or harsh heavy metals. The functional additives are non-radioactive, naturally derived, and have passed comprehensive dermatological irritation tests.
Yes, we provide flexible customization. Fabric weight can be adjusted between 30g/㎡ and 200g/㎡, and raw fiber ratios (polyester, viscose, cotton, bamboo fiber) can be modified to balance softness, strength, breathability, and cost according to your application.
The fabric emits far-infrared rays in the 8–14μm wavelength band, which matches the natural absorption spectrum of human tissues. This gently promotes capillary microcirculation, increases local surface temperature by 2–3°C, and assists in easing muscle soreness.
