There are several factors to consider when buying cleanroom wipes. Among these are absorbency, durability, particle retention, and fabric. Absorbency measures how well a wipe is able to remove waste and clean surfaces. Similarly, the release of liquid is another factor to consider. A well-engineered wipe can release the liquid evenly and maximize coverage. It is important to select a soft wipe if the wipes will be used on sensitive cleanroom equipment.
Fabric for cleanroom wipes has many benefits. Nonwoven wipes are made of polyester and cellulose fibers, which are bonded by hydroentanglement, a process that uses high-pressure water jets to spin the fibers into fabric. Nonwoven wipes are chemically pure and don’t leave residues, and the polyester component is strong and offers excellent oil absorption. Natural fibres are also durable and strong, and are used in blended cleanroom wipes.
Fabric cleanroom wipes are great for critical-process cleaning applications because they resist abrasion and fiber release. These wipes are available in both pre-moistened and dry options, and they feature clean-cut edges. They are a great choice for biotechnology, pharmaceutical, and electronics applications. Fabric cleanroom wipes are also environmentally friendly. The materials used for manufacturing them are usually safe to use, reducing the risk of contamination in sensitive areas.
The most absorbent cleanroom wipes are made of 100% knitted polyester, which are tough and durable. They also do not dissolve in cleaning fluids. Fabric cleanroom wipes made from woven or knitted material come in various quality levels and can be compared based on the level of contamination they can contain. Reclaimed fabric is the cheapest, while “mill end” material is next-cheapest. These wipes may contain dyes and permanent press chemicals that can increase contamination concerns.

There are many factors to consider when selecting cleanroom wipes. The absorbency and release properties of wipes determine how effectively they can remove soiling and debris. High-absorbency wipes will keep surfaces clean and prevent the formation of lint, but they should be packaged in static-free wrappers and sealed tightly to prevent evaporation. The more absorbent wipes may leave fibres or residues behind, which is why they should be selected with care.
Absorbency of cleanroom wipes is measured on a weight basis, and can be intrinsic or extrinsic. The former is the most basic measurement, and is based on the amount of liquid absorbed per square meter. Some wipes are designed to clean fluids and lacquers, while others are suited for water-based contamination. While the cleanest wipes can be used in cleanrooms, they may leave residues behind, which is not desirable. Non-woven cleanroom wipes are the cheapest. They are generally made of fabric or paper. Hybrid non-woven wipes are made from special fabrics and are single-use.
Among the types of cleanroom wipes, nonwoven polyester cellulose is the most common. This material is economical and boasts high absorbency. However, it tends to release more fibers and particles into the environment. However, if air particulate requirements are low, polyester cellulose wipes are an excellent choice. Polypropylene wipes do not absorb very well and are typically pre-saturated. They are used as carriers for liquid applications.
There are three types of cleanroom wipes: non-woven, blended fiber, and synthetic. Non-woven wipes are the most common type, with non-wovens having a low linting characteristic and synthetics possessing superior chemical resistance. These wipes have low NVR, making them an excellent choice for less-critical ISO 5-8 cleanroom environments. But what makes synthetic wipes superior to natural fibers?
Non-woven wipes are made by bonding yarns and fibers together with either mechanical, thermal, or solvent bonding. There are several different types of non-woven wipes available, with the most common being hydro-entangled. Non-wovens are less susceptible to particle shed, but they do have a disadvantage: they are less absorbent than their non-woven counterparts. Non-woven wipes can be more absorbent than cellulose-based wipes.
Polyester cleanroom wipes are made of continuous filament. These wipes are low-lint and strong, and can withstand high-temperature and solvent exposure. The high-density polyethylene material is a durable option for ISO 3 – 5 cleanrooms, and is commonly used in finished products and research work areas. They are also gamma-irradiated for sterility.
The particle retention ability of cleanroom wipes is dependent on the amount of moisture they contain. Pre-wetting wipes with capillary hydroscopic forces will enhance their ability to capture particles. The moisture on wipes also helps to retain particles once they have been removed from a surface. Wet wipes are the most effective method of cleaning cleanroom surfaces. Care must be taken not to over-wet wipes because excessive moisture will lead to particles moving around and re-depositing on the cleanroom surface.

Pre-saturated wipes are highly effective in capturing particles, dissolving dirt, and disrupting biofilms. Pre-saturated wipes also have a lower surface tension, reducing particle binding force. This is the key to cleaning a cleanroom. Proper use of wipes is a critical process in a pharmaceutical cleanroom. However, many companies are still unsure of whether or not they should invest in cleanroom wipes with particle retention.
Microfibre is the most common material in cleanroom wipes. Microfibre has a high sorptive capacity, but is expensive. Furthermore, microfibre products are not suitable for single use, as they can be degraded and cross-contaminated through laundering. Nevertheless, microfibre cleanroom wipes retain particles better than cotton. Read this article to know more about microfibre cleanroom wipes.
Pre-wetting cleanroom wipes are a convenient, time-saving way to disinfect surfaces in critical environments. These wipes are specially formulated to eliminate the risks associated with working with chemical solvents or mixing cleaning agents. They also provide tight control over the concentration of organic cleaning agents while minimizing volatile organic compounds (VOCs).
Presaturated cleanroom wipes are particularly effective at removing particles, disturbing biofilms, and removing residues. Since particles are the most common contaminant, their ability to attract and trap them is critical. A wipe’s ability to trap and retain particles depends on the structure and the size of the contaminant. Prewetting cleanroom wipes improve particle removal by increasing their solubility. However, the ability of pre-wetting cleanroom wipes to repel particles depends on the solvent used and the type of saturating agent.
Presaturated cleanroom wipes are superior to non-presaturated wipes because they are composed of 100% polyester microfiber yarn. This tightly knit filament structure is far more cohesive than previous generations of microfiber materials. As a result, they are more effective than conventional wipes at reducing bioburden on surfaces. This technology enables manufacturers to achieve greater productivity and repeatability while reducing VOC emissions.
Texwipe pre-wetting cleanroom wipes are soaked in IPA or DI water prior to being used. They are also packaged in convenient dispensers. They can be used both inside and outside of cleanrooms. They are also available in Sterile and Saturated Industrial Solvent formulations. If you’re looking for a solution for your contamination control needs, these wipes are the answer.
Safer cleanroom wipes are essential in controlled environments where the spread of bacteria and viruses can pose a health risk. This type of wipe is manufactured using gamma irradiation, a process that ensures low pyrogen levels and other bacteria and virus fragments. They are ideal for disinfection and cleaning in pharmaceutical compounds, medical devices, and other environments that require sterility and containment.
Pre-wetted wipes provide context and minimize time and space by allowing easy access. They can also reduce the possibility of too much or too little cleaning and ensure proper solvent saturation. A pre-wetted wipe also increases consistency and helps maintain cleanroom standards by minimizing volatile organic compounds. Regardless of the type of wipe, it’s crucial to use the correct wipe for the application. And make sure that it’s pre-wet before you use it.
Quality cleanroom wipes have low lint and can be used for many purposes. Polyester lint-free wipes are a good choice, as they are non-abrasive and resistant to mechanical and chemical attacks. Jet black wipes are recommended, since they can better visualize remaining contaminants. Blue wipes are not acceptable. Cleanroom wipes that are too absorbent won’t be effective. They must have low lint to keep the environment sterile.
