When choosing a cleanroom wipe, there are several factors to consider. Lint-free wipes are essential in ISO-rated cleanroom environments. There are many types of cleanroom wipes to choose from, including Synthetic fibers, Laundered polyester, Nonwoven, and Ultrasonic Sealed Edge. This article will explain the different types of cleanroom wipes and how they differ. If you are looking for a new wipe for your next cleanroom, start with your research and find the best product for your needs.
The primary differences between cotton and synthetic fibers in cleanroom wipes are their chemical resistance and heat tolerance. Cotton wipes are more absorbent, withstand high temperatures, and are eco-friendly. Synthetics, on the other hand, are more resistant to water and particles, and are better for cleaning sensitive materials like glass. However, synthetics can be more absorbent. Whether you need synthetic wipes for a critical environment, or for general cleaning and maintenance in a less-critical environment, you should consider their performance.
When it comes to absorbency, natural and synthetic wipes both have advantages and disadvantages. Natural fibers have advantages over synthetics, including high temperature resistance and softness. However, natural fibers are not acceptable in many cleanroom environments due to their high particle shed. Blended fibers are the most common configuration of cleanroom wipes. Blended fibers are non-woven materials that combine the clean properties of synthetics with the softer feel of natural fibers.
A wipe with good abrasion resistance is best for delicate surfaces. Typically, wipes with low particle and extractable counts are best for surfaces such as mirrored screens, lenses, and semiconductor wafers. Polyester wipes are softer than those with non-woven cellulose. They are also more expensive than their synthetic counterparts. The trade-off between fabric quality and cost is the most critical factor when choosing a wipe for your cleanroom.
The synthetic fibers used in cleanroom wipes are often made from polyester. Polyester is a non-shedding synthetic fiber that is low in NVRs. The outermost fibres of these wipes act like microscopic squeegees, trapping the particles. In addition, they are non-shedding and can withstand gamma-irradiation. These qualities make polyester wipes a great choice for cleanroom environments.
This type of wipes is most commonly used in Class 10 to 100 critical environments. Made from 100% continuous filament polyester, this type of wipe is available in laundered and unlaundered versions. They are also available in several different weights and hemmed edges. These wipes are highly durable and have a low lint content. They are often selected for cleanroom applications requiring residue control. Additionally, these wipes have sealed edges, which eliminates the possibility of fibre shedding.
These wipes are made from 100% continuous filament polyester fabric, which means they are completely lint-free. They are also incredibly soft and absorbent, making them a great choice for sensitive cleanroom surfaces. They are also made from a double knitted polyester fabric, which means they won’t cause any irritation to sensitive surfaces. This makes them ideal for cleanrooms where cleanliness is paramount.

Lint-free wipes are essential for many cleanroom applications, but there is an exception. Lint is an inherent part of all fabrics. But Laundered polyester cleanroom wipes are lint-free. Their double knitted structure and laser-sealed edges ensure a lint-free experience for the user. Additionally, these wipes are safe to use with chemicals, and they’re ISO Class 3-5 certified.
When choosing cleanroom wipes, you should look for lint-free cleanroom wipes that are abrasion resistant and economical option. Laundered polyester wipes are highly absorbent and do not require high absorption rates, which makes them an ideal choice for controlled environments. These wipes are usually produced in large rolls rather than being cut into individual units, which increases the risk of fibre contamination. They are also heat-sealed to prevent linting.
Lint-free nonwoven cleanroom wipes are ideal for general-purpose cleaning in ISO Class 5 cleanrooms. They combine virgin polyester and cellulose fibres to form a super-tough fabric with virtually no particle generation. They are cleanroom-laundered, resulting in a lint-free wipe. Nonwoven cleanroom wipes are an effective way to prevent cross-contamination and minimize your cleaning time.
Nonwoven wipes are pre-saturated to prevent the need for high absorbency. They are made of lint-free polyester and are often manufactured in rolls rather than individual units. Cutting the wipes into individual units increases the chance of fibre contamination. Heat-sealed edges prevent fibre shedding and laser-cut edges minimize linting. And because non-woven wipes do not have a fabric backing, they are often reusable.
Lint-free cleanroom wipes have lower lint than a normal cleaning cloth. Nonwoven cleanroom wipes are the most common type of cleanroom wipes available. Lint-free cleanroom wipes are also known as lint-free paper towels. However, this is not entirely true because cellulose wipes are made from lint-containing fibers. The most lint-free cleanroom wipes are made from polyester and pre-laundered in a clean room.
Nonwoven cleanroom wipes differ in the amount of lint that they contain, their efficiency in absorbing liquids, and their essential properties. They are classified by their use in industrial settings and ISO classes. They are ideal for pharmaceutical, chemical, and optical industries. Their low lint content makes them suitable for use in the medical and pharmaceutical industries. And they are also ESD-safe, allowing for tighter contamination control.
Ultrasonic Sealed Edge
There are two types of ultrasonic cleanroom wipers available in the market today: laser slitting and ultrasonic slitting. Laser slitting is more cost-effective than ultrasonic slitting, but ultrasonic slitting produces softer edges and lower carbon levels. Ultrasonic sealing also helps the wiper retain fiber, making it ideal for scratch sensitive applications.
The most durable type of Ultrasonic Sealed Edge cleanroom wipe is the MicroSeal(r) LI. They are made of 100% polyester continuous filament yarns for durability and chemical compatibility. They are the only wipes on the market with this advanced edge-sealing technology. And despite the strong and durable construction, the wipes are lint free, too.
The ultrasonic heat process imparted by ultrasonic wipes bonds the fibers together without cutting. The result is a wipe with the highest cleanliness and minimal carbon levels. Controlled cleanroom environments are also safer for production, because particulate levels are strictly monitored. The level of particulate in the environment must not exceed a pre-determined limit. Ultrasonic Sealed Edge cleanroom wipes are lint free, ensuring a sterile environment.
High-quality, lint-free cleanroom wipes offer high performance in a variety of applications. Polyester lint-free wipes are soft, non-abrasive, and feature a fast-drying dense-weave for increased absorption and minimal lint. These wipes also have synthetic fibers that resist wear and tear and keep cleanrooms lint-free.
If you have to wipe something down in a Cleanroom, you’ll want to look for lint free products. Chenigen cleanroom wipes are designed for this type of environment, offering two-layer construction and a thick, durable texture. They’re made of a nonwoven polyester cellullose blend, and can be purchased in sizes ranging from 4’x4′ to 18’x18′.
Although the label says “lint-free,” they are not 100% lint-free. In fact, even the cleanest wipes still produce some lint, according to particle testing. Lint is short, fine fibers generated by a wipe’s material. Lint can be created by the use of various materials, including man-made polyester and nylon, natural cotton, hydro-entangled polyester-cellulose, and a variety of other materials.
