ESD ladies' coat short sleeve white, 155 g/m² compact cotton with conductive yarn - A1-ESD

In final inspection and metrology the decisive view is the one from above. Anyone checking a populated assembly under a stereo microscope should not have to guess whether a pale fibre came from the coat or from the component tape. White workwear makes its own condition visible and enforces a disciplined change interval.

The coat is built for that role. 155 g/m² of compact cotton yarn blended with polyester sheds very little fibre, and the conductive yarn runs through the fabric as a continuous grid at 4 %. Surface resistance was measured at STFI at 10⁵ to 10⁷ ohm, inside the dissipative range.

Then there is the practical side. The notched lapel collar, the concealed press-stud placket, three pockets and a sweat guard at the neck are details that make themselves felt over an eight-hour shift rather than in product photography.

Your benefits

• Contamination stays visible: On white fabric every flux splash and every grease mark shows immediately. Close to a cleanroom that is not a drawback but the inspection function of the garment.
• 4 % conductive yarn throughout: The conductive yarn is woven in rather than applied on top. It cannot be rubbed off when a sleeve passes over the edge of a test fixture several hundred times a week.
• Concealed press studs: The placket sits under a fabric flap. Neither during placement work nor while handling housings does bare metal reach the assembly on the bench.
• Slanted side pocket openings: The openings are angled so the hand finds them while seated. Microscope and measurement stations are worked at sitting down for most of the shift.
• Dimensionally stable in laundry: The 48 % polyester share holds length and cut across many cycles. The coat comes back from the laundry in the same size it was issued in.
• Light at 155 g/m²: White coats are frequently worn over the wearer's own clothing. At 155 g/m² that second layer stays bearable across a full shift, including in summer.
• 3XS to 6XL from one series: Twelve sizes in the same cut mean visitors, trainees and permanent staff can all be equipped from a single stock holding.

Construction in detail

The front closes with a concealed press-stud placket. The fabric flap above it keeps the studs away from the bench, which matters at stations with open assemblies and sensitive surfaces. There is a patch chest pocket on the left plus two side pockets with slanted openings. The ESD logo sits on the right side pocket.

A sweat guard is worked into the neck. It absorbs moisture before it reaches the collar, and on a white coat that matters more than usual, because a discoloured collar cannot be hidden. The side bust darts give the notched lapel collar the support it needs to hang cleanly.

Fabric and material

The fabric is 48 % cotton, 48 % polyester and 4 % conductive yarn at 155 g/m². The cotton is compact spun, so fibre ends stay largely bound into the yarn. For a white coat in particle-sensitive areas that is the decisive property, because pale lint is precisely what stands out on dark components.

Polyester delivers dimensional stability and short drying times, cotton delivers handle and moisture uptake. The blend wears differently from pure synthetic fabric, which traps heat quickly under task lighting and above soldering stations. Across an eight-hour shift that difference is noticeable.

• Compact-spun cotton yarn, low lint
• Colour white

Fit and size range

Twelve sizes from 3XS to 6XL cover the whole workforce. With white coats, which are often issued to visitors, auditors and training participants as well, a wide size range is genuinely useful, because guests cannot be distributed across two universal sizes.

The oversizes from 3XL upwards run in the same cut, so a stock holding can be extended upwards at any time. Exact measurements per size are given in the size chart, available as a PDF in the Downloads tab of this product page. The short sleeve keeps wrist and forearm clear.

Lasting dissipation and wash resistance

Dissipation comes from the woven-in conductive yarn. The yarn used is high-grade silver yarn processed in a method of our own, so it sits inside the fabric rather than on top of it. Conductivity is retained after repeated washing and wearing, which counts double for white garments with their more frequent laundry cycles.

STFI measured a surface resistance of 10⁵ to 10⁷ ohm in a test climate of 23 (±1) °C and 25 (±5) % relative humidity. That dry environment is chosen on purpose, because low humidity is where charges build up most easily and persist longest. Heated production halls in winter behave in much the same way.

• Conductive yarn woven in, not a coating
• Silver yarn processed in a method of our own
• 10⁵ to 10⁷ ohm to DIN EN 61340-5-1:2016
• Suitable for industrial laundry

White close to the cleanroom

White is the colour for everything heading towards cleanroom anterooms, measurement labs and final inspection. The condition of the garment can be judged at a glance, so a soiled coat gets changed instead of worn on. During audits and customer visits that reads differently from a grey coat whose wear nobody can see.

White also suits visitor and training areas, because affiliation is obvious at once. For benches with flux, toner and grease the black version is the sounder choice, and cornflower blue marks fixed teams. The cut is identical across all three colours.

Technical data

Applications

• Final inspection and optical checks under the stereo microscope
• Measurement and calibration labs with dissipative equipment
• Cleanroom anterooms and airlock zones of an EPA
• Visitor, audit and training areas inside production
• Incoming inspection of semiconductors and component tapes

Care and service life

The coat is suitable for industrial laundry and returns at the same length and width, because the polyester share holds the cut. Conductivity of the woven-in yarn is retained across many wash cycles. We state no wash temperature here, the care label inside the garment is the reference.

Finishing and custom versions

On white, embroidery and printing come out with strong contrast. Printing up to 160 °C is possible and a sample print in advance is recommended. Press stud or pocket in a contrasting colour, company logos, special colours and special finishing are arranged on request. Ask us for a quotation.

Standards and testing

The coat was tested to DIN EN 61340-5-1:2016 for dissipation and surface resistance, the test institute being STFI. The measured value is 10⁵ to 10⁷ ohm in a test climate of 23 (±1) °C and 25 (±5) % relative humidity. Further ESD standards were neither tested nor certified. The garment complements flooring, footwear and work surfaces in an EPA.
