Wipers and Swabs

Wipers and swabs are specially designed to enable engineers and technicians to carefully clean critical surfaces. Well constructed and carefully designed wipers and swabs play a crucial role in laboratories and fab operations. Products used in such kind of areas demand a lot of hygiene and typical laundry wash in order to ensure that they are absolutely free of any contamination and dirt before further use.

Wipers for Different Classes of Cleanroom

A cleanroom is a special room with yellow light and controlled level of pollutants, such as dust particles, vapors and microorganisms. Since it is typically used in scientific research and lab operations, it is specially proofed from any kind of contamination. Cleanroom is divided into different classes according to the volume and size of particles per cubic meter. These classes represent the number of 0.5 µm particles allowed per cubic foot. Therefore, class 1,000 will denote 1,000 particles of size 0.5 µm per cubic foot of air. Here is a guide for which kind of wipers should be used in these different classes of cleanroom:

Wiper Fabrics

Synthetic fabrics, such as polyester and nylon are used for class 1,000 or under while blended and cotton wipers are used for higher classes.

  • Polyester: Polyester has the quality of absorbing fluids but cannot absorb water. For this purpose a special kind of polyester, called hydro-entangled polyester, is used. It is created by exposing polyester to the high pressure of water. It is similar to knitted wipers but is much lighter and efficient in use.
  • Nylon: Constructed in a similar way to polyester, the major advantages of nylon wipers are their resistance to heat and abrasion.
  • Poly cellulose blend: These wipers are a blend of polyester and cellulose and combine the qualities of both. While they possess high absorbency on one side, they also have the properties of better cleanliness and strength of synthetic fiber.
  • Cotton: For cleaning the heated surfaces, synthetic wipers are unsuitable, since they are likely to melt. Cotton wipers are durable and also absorb aqueous solutions.
  • Foam: Foam wipers are highly absorbent and have great capacity to carry liquids.
  • Composite: These wipers have an outer poly layer and an inner cellulose layer. By the virtue of both these fabrics, they are highly absorbent as well as stay clean due to their synthetic outer layer.

Swabs

Swabs are used for cleaning products in case any dirt or contamination is left out there. Some swabs have white fabric on one side and black fabric on the other side so as to enable professions to spot particles quickly and efficiently.

Components of Swabs

A swab consists of a handle and a cleaning head attached to it.

  • Handle: A swab handle is typically made of polypropylene and comes in various sizes, lengths and widths. Other kind of material used for handle may be wood, plastic or some alloy.
  • Head: Like wipers, swab heads are also made of knitted polyester, cotton and foam. Out of these, polyester knit swab is easy to use and can be laundry washed in order to ensure cleanliness. Hydro entangled polyester swabs and foam swabs are extremely lightweight and highly water absorbent. Cotton fabric is generally used in delicate industrial and lab applications.

These swabs are available in different shapes and can be chosen according to the nature and delicacy of the work application.
