In the world of electronics manufacturing, semiconductor production, and pharmaceutical research, controlling electrostatic discharge (ESD) is paramount. Cleanroom environments, with their stringent requirements for particulate and contamination control, demand specialized fabrics that can safely dissipate static electricity.
What are ESD Fabrics?
ESD fabrics are engineered textiles designed to safely dissipate static charges. They achieve this through the incorporation of conductive or dissipative fibers, such as carbon, stainless steel, or special polymers. These fibers allow static electricity to gradually drain away, preventing the sudden and potentially damaging discharge that can occur with insulating materials.
Key Characteristics of ESD Fabrics:
- Static Dissipation: The primary function is to safely and quickly dissipate static charges.
- Low Particle Generation: Cleanroom environments require minimal particulate generation. ESD fabrics are designed to minimize the release of fibers and dust.
- Chemical Resistance: Depending on the application, resistance to chemicals used in cleaning and sterilization processes is crucial.
- Comfort and Durability: Cleanroom garments must be comfortable for wearers and durable enough to withstand frequent laundering and wear.
Applications of ESD Fabrics in Cleanrooms:
- Cleanroom Garments:
- Smocks, coveralls, and hoods
- Gloves and shoe covers
- Wiping Materials:
- Cleanroom wipes for delicate equipment and surfaces
- Liners and Covers:
- For workstations, equipment, and sensitive components
ESD Standards:
- EN 61340-5-1: This standard provides guidance on the selection, use, and maintenance of ESD control materials and equipment within an ESD protected area.
- EN 1149: This standard specifies the requirements for materials and garments with electrostatic properties. It covers various aspects, including surface resistivity, volume resistivity, and the ability to dissipate static charges.
- EN 61452: This standard specifically addresses the requirements for electrostatic protective clothing. It outlines performance criteria, test methods, and labeling requirements for garments designed to control electrostatic discharges in sensitive environments.
XM Textiles ESD Fabric Recommendations:
XM Textiles offers a range of high-performance fabrics suitable for cleanroom environments. Here are a few key recommendations:
- CleanStatic-110:
- CleanStatic-110 is an antistatic fabric made from 98% polyester and 2% antistatic carbon fibre. This antistatic fabric has a plain weave and Belltron antistatic yarn which is gridlocked into the surface of the fabric.
- CleanStatic-110 is designed for lightweight antistatic garments for CleanRooms.
- Complies with EN 1149, EN 61340-5-1
- CleanStatic-140:
- CleanStatic-140 is an antistatic fabric. Antistatic fibres safely dissipate static electricity, eliminating the risk of gas explosion and destruction of electronic components. This static dissipative fabric has a twill weave and Belltron static dissipative yarn that is gridlocked into the surface of the fabric.
- A CleanStatic-140 is designed for antistatic garments for cleanrooms (protection of electronic equipment from electrostatic discharge)
- Complies with EN 1149
- CleanStatic-240:
- CleanStatic-240 TC is an antistatic fabric made of 65% polyester, 33% cotton and 2% antistatic carbon fibre. This antistatic fabric has a twill weave and the addition of Belltron antistatic yarn which is gridlocked into the surface of the fabric.
- CleanStatic-240 is designed for antistatic garments for CleanRooms.
- Meets the requirements of EN 1149-5, EN 61340-5-1
