Magnetic Spunlace Nonwoven Fabric Products

1. Product Foundation: Core Characteristics and Advantages of spunlace Nonwoven Fabrics, Establishing the Foundation for Functionality

The practical value and user experience of magnetic spunlace nonwoven fabrics stem from the outstanding characteristics of spunlace nonwoven fabrics themselves. Our company selects polyester, viscose, cotton, and bamboo fiber as core raw materials, relying on mature water stitch technology to create substrates. The core characteristics not only provide support for the stable loading of magnetic additives but also become the key advantages for product adaptation to multiple scenarios:

Flexible and skin-friendly without restrictions, suitable for various scenarios: The spunlace process uses high-pressure water flow to make fibers interlock, forming a mesh structure without longitudinal and transverse differences. The base material 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 the skin, suitable for medical protective gear, intimate care products, etc. in direct contact with the human body; polyester substrates have both flexibility and stiffness, can meet the requirements of industrial magnetic adsorption and home magnetic decoration for stable form, and different material ratios can achieve customized touch sensations of "soft without wrinkles, tough without hardness", suitable for bending, folding, etc. complex usage forms.

Breathable and moisture-absorbent without heat, enhancing the user experience: The fiber gaps of water stitch substrates are uniform and have a porous structure, with better breathability than traditional nonwoven fabrics - the breathability of cotton and bamboo fiber substrates can reach 1500-2200mm/s, the moisture absorption rate of viscose substrates is ≥9g/10min, which can quickly conduct water vapor and sweat, avoiding the discomfort of sweating and stickiness caused by prolonged skin contact (such as medical waist protectors, magnetic underwear); even polyester substrates also optimize the ventilation channels through fiber modification to achieve a balance of "magnetic function + ventilation experience", suitable for outdoor protection, industrial long-term use, etc. prone to sweating scenarios.

Strong and durable, reducing usage costs: The spunlace process makes fibers closely intertwined, the breaking strength of the base material is significantly better than that of ordinary nonwoven fabrics - polyester substrates have a longitudinal breaking strength of ≥850N/m and a transverse strength of ≥550N/m, and are not prone to damage from repeated stretching and friction; after scientific ratio blending, full cotton and bamboo fiber substrates can also withstand daily washing and wear and tear, avoiding the degradation of base material strength caused by loading magnetic additives; even after multiple washes, the base material can still maintain structural stability, the magnetic additives are not prone to fall off, extending the overall product lifespan, and reducing customer replacement costs.

Environmentally friendly, safe, and without irritation, suitable for sensitive groups: The selected polyester, viscose, cotton, and bamboo fibers all meet the OEKO-TEX® Standard 100 environmental standards, without formaldehyde, harmful heavy metals, and full cotton and bamboo fibers are even natural biodegradable materials; the water stitch process does not require the addition of adhesives, the base material has no odor or irritation, ensuring safety from the source, suitable for mothers and infants, the elderly, postoperative patients, etc., who are sensitive to materials, especially suitable for medical rehabilitation, intimate care, etc. scenarios. Flexible and adaptable design, meeting individual needs: Based on the customer's functional and scenario requirements, the raw material ratio can be flexibly adjusted - pursuing a soft and breathable feel, increasing the proportion of viscose, cotton, and bamboo fiber (such as 50% cotton + 50% viscose); pursuing durability and wear resistance, increasing the proportion of polyester (such as 75% polyester + 25% bamboo fiber); the base material weight (35-200g/㎡ adjustable), thickness, and density can all be customized. At the same time, it can be adapted to two magnetic processing methods: immersion and coating, ensuring a perfect match between the base material characteristics and magnetic function, maximizing the product value.

II. Core Technology: Dual loading of magnetic additives through immersion and coating to achieve precise functional implementation

Our magnetic spunlace non-woven fabric strictly follows the step-by-step processing mode of "first preparing high-quality spunlace base material, then performing magnetic additive finishing". According to different scenarios, the requirements for magnetic strength and magnetic distribution are targeted. The core processing methods are immersion and coating, through meticulous control to ensure the uniform attachment and stable effect of the magnetic additives, while not damaging the original characteristics of the spunlace base material:

Selection of magnetic additives: Safe and efficient, suitable for multiple scenarios: Select nano-level magnetic particles that comply with national medical standards (mainly composed of ferrite magnetic powder, with magnetic field strength adjustable from 500 to 3000 gauss), without radioactivity or chemical toxicity, and tested for skin irritation (no redness or itching reactions), safe for use in skin-contact scenarios; The particle size is controlled at 10-50nm, with good dispersion, not prone to agglomeration, ensuring uniform magnetic distribution, avoiding strong or weak local magnetic fields.

Dual processing methods: Choose as needed, function adaptation:

Immersion method: Full-width penetration, uniform magnetic field without dead zones: Suitable for scenarios requiring overall uniform magnetism (such as medical protective gear, magnetic mattresses), fully immersing the spunlace base material in the magnetic additive solution (concentration adjustable from 2% to 5%, customized according to magnetic field strength requirements), low-speed stirring (30-50r/min) ensures uniform dispersion of magnetic particles, precise control of immersion time (20-30 seconds), allowing magnetic particles to fully penetrate the fibers; Then, through double-roller precise drying (pressure 0.4-0.7MPa, liquid content 70%-90%), remove excess solution; Finally, through low-temperature hot air curing (85-100℃), the magnetic particles form a stable bond with the fibers, after 15 washes, the magnetic field strength attenuation ≤ 8%, the full-width magnetic field distribution error ≤ 5%.

Coating method: Local precision, magnetic effect focused: Suitable for scenarios requiring local magnetic focus (such as acupoint therapy patches, magnetic adsorption strips), using high-precision scraping tools or spraying equipment, coating the magnetic slurry (magnetic particles + environmental-friendly adhesive) according to the preset pattern on the spunlace base material surface, coating thickness (10-50μm adjustable), magnetic area shape can be customized; After coating, it is subjected to infrared curing (90-105℃), ensuring the magnetic layer is closely adhered to the base material, not prone to peeling; The local magnetic field strength can be precisely increased to above 3000 gauss, meeting the needs of acupoint therapy, precise adsorption, etc., while the non-magnetic areas retain the original breathable and skin-friendly characteristics of the base material.

Base material adaptation optimization: Process fine-tuning, retaining core advantages: Adjust processing parameters according to different base material characteristics - for highly absorbent cotton, viscose, and bamboo fiber base materials, use low-concentration magnetic solution immersion + short-time low-temperature curing to avoid hardening of the base material affecting the skin feel; For hydrophobic polyester base materials, perform plasma surface treatment before immersion to enhance adsorption force, and select suitable adhesives for coating to ensure a firm attachment of the magnetic layer; Finally, achieve the effect of "magnetic function loading without sacrificing the basic experience of the base material".

III. Unique product features: Magnetic function + base material advantages combined, creating core competitiveness Based on high-quality spunlace substrates and precise magnetic processing technology, our magnetic spunlace non-woven fabric possesses the unique advantage of "substrate characteristics + magnetic function" that is a double-layered combination.
