Ten-thousand Level Clean + AI Quality Inspection: Jiangsu Noda Factory How To Create “lead Allergy”disposable Underpads”

With the acceleration of the aging society and the rising demand for medical care, the market for adult diapers and care pads is experiencing explosive growth. In this field, Jiangsu Noda Hygiene Products Co., Ltd. has become a leading manufacturer of adult incontinence care products in China by virtue of its high-standard clean room production system. In this article, we will analyze the core technology, production management and industry value of its clean room, showing the company's commitment to quality and responsibility.

Industry Background and Noda's Positioning

The global adult incontinence care market is expected to exceed USD 20 billion in 2025, with China, as the country with the largest aging population, experiencing a market demand growth rate of more than 15%. However, since the care products are in direct contact with sensitive skin, the cleanliness of the production environment, the safety of raw materials and the precision of the process are directly related to the health of users. Founded in 2010, Jiangsu Noda focuses on the adult care field, with “medical-grade production standards” as its core competitiveness, and its products cover the needs of high-end medical care pads, home care diapers and other full-scene needs, and its cooperative customers include tertiary hospitals, senior care chain organizations and well-known e-commerce brands.

The hardcore strength of a cleanroom

Environmental control: clean system that exceeds national standards

Noda's clean room adopts ISO Class 7 (Class 10,000) cleanliness standard, and the key area locally reaches ISO Class 5 (Class 100). Through the triple filtration system (primary + HEPA + ULPA) to achieve air cleanliness ≤ 3520 particles / m ^ 3 (≥ 0.5 μm particles), the number of air exchanges per hour more than 50 times, the temperature and humidity is accurately controlled at 22 ± 2 ° C, 55 ± 5% RH, to ensure that microbial breeding risk tends to zero. The workshop is equipped with differential pressure gradient monitoring to prevent cross-infection.

Intelligent production equipment

Fully automatic polymer core production line

Adopting foreign imported SAP non-woven fabric molding technology, to achieve the water-absorbing resin (SAP) and fluff pulp nanoscale uniform mixing, water-absorbing rate enhancement within 3 seconds, the amount of water locking up to their own weight 30 times.

Ultrasonic glueless review process

Abandon the traditional adhesive, through high-frequency vibration fusion of the surface layer of non-woven fabric and impermeable membrane, eliminating formaldehyde residue, breathability increased by 40%.

AI visual quality inspection system

Based on deep learning algorithms, real-time detection of product thickness, embossing uniformity and minor defects, defective product rejection accuracy of 99.98%.

Innovations in Materials Science

Nominal use of two-component ES fiber nonwoven fabrics

Reduced surface friction coefficient (≤0.15) through hydrophilic modification treatment, reducing the risk of skin damage in bedridden patients

Deflector layer with 3D embossing technology

With diamond-form manifold design, the liquid diffusion speed is 2 times faster than traditional products, avoiding local saturation leakage.

Environmentally friendly biodegradable base film

PLA/PBAT bio-based materials developed in cooperation with the Chinese Academy of Sciences, with a natural degradation rate of more than 70% in 180 days, have been certified by China Environmental Labeling Certification

Whole process quality control system

Raw material control

SAP is purchased from foreign imports, and each batch is tested for water absorbency and residual monomer (≤500ppm); the nonwoven fabrics have passed GB/T 28004, ISO13485 and CE certification tests.

Production process monitoring

Online dust particle counter (Lighthouse) sampling every 15 minutes, microbial sampling dish according to GB15979 standard daily sampling, colony total ≤ 20CFU/g.

Finished Product Testing Laboratory

Simulated use test

Robotic arm simulates 500 wear rubs to detect surface integrity

Moisture permeability test

ASTM E96 ≥2000g/m²-24h

Toxicological safety

Passed ISO 10993 cytotoxicity and skin sensitization tests

Scenario-based solutions

Medical Scenarios

Ultra-thin nursing pads (1.2mm thickness) developed for postoperative incontinence patients with a breathable, anti-mold and anti-bacterial layer to reduce the risk of ICU-acquired infections.

living at home in one's old age

Germany henkel urine display process, sensitive disappearance, timely reminder of replacement, reduce bed sores occurring

Environmental upgrading

Looking forward to the launch of the “Plant-Based Care Pads Series”, which is 100% recyclable from raw materials to packaging, with a 35% reduction in carbon footprint, we are committed to our expectations and endeavors.
