A Comprehensive Overview of Low Lint Cleanroom Wipes for Cleanroom Cleaning and Maintenance
Cleanroom wipes vary based on their intended use, cleanliness levels, materials, and key attributes. This article covers essential cleanroom and industrial standards, including ISO classifications, procedures, protocols, ESD-safe properties, and specific applications in manufacturing. Historically, cleanroom wipes have proven to be the most efficient and widely utilized solution for eliminating contaminants, particulates, and residual substances in critical manufacturing and pharmaceutical settings. Their high absorbency and low lint characteristics facilitate effective management of moisture, solvents, and spills while cleaning surfaces, walls, machinery, fixtures, transport carts, tools, and other production materials.
Differences Between Woven and Non-Woven Cleanroom Wipes
What is a Nonwoven Wipe?
Nonwoven fabrics are defined as sheets or web structures bonded through mechanical, thermal, or chemical processes involving fiber entanglement or perforated films. Their unique construction and post-treatment features can lead to advantages such as porosity that allows for gas sterilization. Nonwoven wipes offer a cost-effective option since their manufacturing does not necessitate laundering. Blends of cellulose and synthetic fibers enhance absorbency for spill management and thick liquid removal. Typically, nonwoven wipes are suitable for cleanrooms classified no cleaner than ISO Class 6.
Nonwoven Polycellulose WIpes :
Manufactured from a high-quality blend of 45% polyester and 55% cellulose, which is hydroentangled for optimal performance and purity. This results in a robust and highly absorbent product ideal for effective liquid removal or lint-free wiping in controlled environments

What is a Knit (Woven) Cleanroom Wipe?
Woven wipes, or knitted wipes, play a critical role in contamination control in sensitive environments. These are regarded as the highest quality cleanroom wipes available today, with low non-volatile residue (NVR) levels and excellent particle removal capabilities, suitable for critical-class environments. In contrast to nonwoven materials, woven cleanroom fabrics are created by knitting monofilament or continuous synthetic fibers like polyester. This results in a durable wipe that minimizes shedding and linting, making it compliant with ISO Class 3 and above standards.
Benefits of Woven Polyester Cleanroom Wipes
100% Continuous Filament Polyester: Understanding Knitted Polyester Cleanroom Wipes
Polyester is a synthetic fiber derived from petroleum. Continuous filament polyester cleanroom wipes represent the cleanest wiping option available. The monofilament design ensures high durability and strength. While polyester naturally absorbs solvents, additional treatments are often applied to enhance its absorbent capabilities, particularly for aqueous solutions.
Laundered polyester knit cleanroom wipes are processed using ultra-filtered water, followed by moisture removal through HEPA filtration. The wipes are packaged and sealed in an ISO Class 4 laminar flow workstation to maintain cleanliness and traceability prior to final inspection. This processing and laundering help achieve low particle shedding, consistent quality, and favorable outcomes in Class 3 to 5 cleanrooms. Additionally, these wipes do not shrink or deform and are compatible with cleaning solvents like isopropyl alcohol (IPA), making them suitable for high-precision cleanroom environments.
Double Knitted Polyester Cleanroom Wipes
Double-knitted monofilament polyester offers a soft fabric that enhances durability and particle retention. The dual knitting process creates a cross-hatched texture, increasing surface area for better particle capture compared to standard polyester wipes. The tightly woven structure minimizes the risk of unraveling and filament breakage, further reducing particulate generation.
Polyester Double Knit Wipes The CleanPro Double Knit Pro 9" x 9" wipe is made from 100% double-knit polyester fabric, and is manufactured and packaged in a controlled ISO Class 4 cleanroom environment.

Polyester/Nylon Cleanroom Wipes
This ultra-fine microfiber, made of 80% polyester and 20% polyamide (180 gsm), efficiently removes dirt from delicate surfaces. It is durable, featuring strong tensile, tear, and bursting resistance, as well as chemical and abrasion resistance. Its specialized weave creates a smooth, dense texture with soft loops that enhance liquid absorbency and dirt retention. Laser-sealed edges minimize particle and lint generation, ensuring low levels of particulate, NVR, and ionic presence.

Polyester/Cellulose or Polycellulose Cleanroom Wipes
Polycellulose wipes usually have a composition of 55% cellulose and 45% polyester, which are hydroentangled to create a chemically pure wipe without binders, starches, or thermal bonding. The cellulose component assists with electrostatic discharge (ESD), making these wipes a preferred choice in applications where liquid retention is critical.
Advantages of Cellulose Blended Wipes
The cellulose-to-polyester ratio can vary based on absorbency requirements versus lint generation. Cellulose generally offers higher absorbency, while polyester minimizes linting. Polycellulose wipes are among the most popular options for general wiping and spill control in ISO Class 6 and above cleanrooms. They are biodegradable, naturally ESD-friendly, and are considered one of the most economical choices due to their ease of production and processing. Their desirable attributes include affordability, chemical resistance, and high absorbency.
