In fields requiring extremely high cleanliness such as precision manufacturing, electronic component production, and optical instrument cleaning, ultrafine cleanroom wipes have become indispensable cleaning consumables due to their excellent performance. This article provides a comprehensive analysis of their core features from three perspectives: material composition, technical standards, and pricing structure.

1. Material Analysis: Polyester-Nylon Composite Fiber and Plain Weave Process

The core material of ultrafine cleanroom wipes is microfiber, scientifically blended with 80% polyester (PET) and 20% nylon (polyamide):

• Polyester provides excellent abrasion resistance, tear resistance, and chemical resistance, ensuring the wipe remains durable during repeated use.

• Nylon adds softness and enhances liquid absorption, reducing the risk of scratching delicate surfaces during wiping.

The wipes are manufactured using a plain weave process, tightly interlacing warp and weft fibers to create a uniform and smooth fabric surface. This process significantly reduces fiber shedding and pilling, minimizing particulate residue during wiping to meet stringent cleanliness requirements.

2. Technical Standards: Cleanliness Class, Basis Weight, and Sizes

1. Cleanliness Class

   • Minimum standard: Class 1000 (ISO Class 6), allowing no more than 1000 particles ≥0.5μm per cubic foot of air, suitable for semiconductor packaging and LCD assembly.

   • High-end grades: Class 100 or even Class 10 wipes meet more demanding cleanliness levels, with corresponding price increases.

   • Note: Some small manufacturers may produce ultrafine wipes that do not meet these standards, so buyer caution is advised.

2. Basis Weight Range
   Ultrafine wipes have a relatively high basis weight compared to regular polyester or sub-microfiber wipes, typically ranging from 160g/m² to 220g/m². Users can choose based on specific needs.

3. Common Sizes

   • 4-inch (~10cm×10cm): For precision instruments and miniature component cleaning.

   • 6-inch (~15cm×15cm): For laboratory equipment and optical lens maintenance.

   • 9-inch (~23cm×23cm): For electronic circuit boards and mechanical part wiping.

   • 12-inch (~30cm×30cm): For large surface dust removal or industrial equipment maintenance.

3. Pricing Structure: Multi-Factor Influences

Ultrafine cleanroom wipes generally range from 25 to 100 RMB per pack (usually 100 pieces per pack, 4-inch packs often contain 400 pieces), with key factors affecting price including:

1. Size and Basis Weight
   Larger size and heavier weight mean more material usage and higher cost.

2. Cleanliness Class
   Basic Class 1000 wipes are more affordable; Class 100 or better grades are pricier due to more complex manufacturing and cleaning processes.

3. Packaging and Brand
   Vacuum-sealed packaging and well-known brands carry a premium but offer superior quality and batch consistency, suitable for companies with strict quality demands.

4. Purchasing Recommendations: Match Needs with Cost-Effectiveness

• Electronics Assembly: Choose Class 1000 or Class 100, 9-inch wipes weighing 180g/m² for balanced cost and dust removal efficiency.

• Biological Laboratories: Prioritize Class 100, 9-inch wipes weighing 200g/m² to ensure sterile environments.

• Routine Industrial Maintenance: Economic 9-inch wipes at 160g/m² suffice for basic cleaning tasks.

It is recommended to purchase through official channels and request material test reports and cleanliness certifications to avoid contamination risks from inferior products. Matching technical parameters to application scenarios maximizes wipe performance and supports cost savings.
