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

Anyone running an EPA knows how work coats fail. They sit differently after twenty washes, the fasteners scrape across housings, and the dissipative property turns into a claim nobody can measure. This coat was built around those three weak points.

The fabric combines 48 % cotton with 48 % polyester and 4 % conductive yarn. Cotton carries the handle and absorbs moisture across a full shift, polyester holds the cut and shortens drying time in industrial laundry. At 155 g/m² the coat stays light enough to wear over a blouse or T-shirt without adding bulk.

Black belongs where work is done rather than where visitors are received. Flux residue, solder smoke deposits, toner and machine grease show up on light fabric within days. On black they stay inconspicuous, and that has nothing to do with washing the garment less often.

Your benefits

• Measured 10⁵ to 10⁷ ohm: Surface resistance was determined at STFI in a test climate of 23 °C and 25 % humidity, so the dissipative range is documented rather than calculated on paper.
• Concealed press-stud placket: The studs sit under a fabric flap. When you lean over the bench, no metal drags across bare boards, housing edges or polished assemblies waiting for inspection.
• Three pockets at working height: The patch chest pocket on the left takes a pen and a probe tip. Both side pockets have slanted openings and stay reachable while you are seated at a rework station.
• Sweat guard at the neck: An additional insert takes up moisture before it reaches the collar. That extends the time a coat still looks presentable between two laundry cycles.
• 155 g/m² instead of heavy synthetics: The fabric weight is deliberately low. Across eight hours next to a heated soldering station every gram saved counts for more than any description of wearing comfort.
• Low lint through compact yarn: Compact-spun cotton yarn has very few protruding fibre ends. That means less loose material on open assemblies, in test chambers and on microscope stages.
• Twelve sizes from 3XS to 6XL: Small and large builds are served from the same shelf. New staff receive their coat on day one instead of waiting for a special order to arrive.

Fabric and material

The base is compact-spun cotton yarn blended with polyester, at 48 % cotton and 48 % polyester plus 4 % conductive yarn. Compact yarn has fewer protruding fibre ends than conventionally spun yarn, which is why the fabric sheds almost no lint onto open assemblies. Dimensional stability comes from the polyester share.

155 g/m² sounds modest and is exactly the right order of magnitude for a work coat. Heavy synthetic fabric traps heat above a soldering station, while a fabric that is too thin loses its contour quickly. This blend stays wearable across a full shift and still holds the shape a notched lapel collar needs.

• 48 % cotton for handle and moisture uptake
• 48 % polyester for dimensional stability and short drying times
• 4 % conductive yarn as a continuous grid in the fabric
• 155 g/m² fabric weight
• Low lint thanks to compact-spun yarn

Construction in detail

The notched lapel collar hangs cleanly because the side bust darts pull the front of the coat into shape. This is not a fashion detail. A coat that creases across the chest drops onto the bench when the wearer leans forward, and that is exactly where components, boards and test adapters are lying.

The front closes with a concealed press-stud placket, the studs sitting under a fabric flap. A sweat guard at the neck absorbs moisture before it reaches the collar. The ESD logo is placed on the right side pocket, which keeps it visible while the wearer is seated at the workstation.

Lasting dissipation and wash resistance

The conductive yarn is distributed through the fabric at 4 % and forms a continuous grid. It is not a coating that can wear away. The yarn used is high-grade silver yarn processed in a method of our own. Conductivity is retained after repeated washing and wearing.

For purchasing this is a service-life question. A coat that drops out of specification after thirty washes costs more than one that stays in stock. Testing at STFI produced 10⁵ to 10⁷ ohm at 23 (±1) °C and 25 (±5) % relative humidity, that is under dry conditions where charges are particularly persistent.

• 4 % conductive yarn throughout the fabric
• Silver yarn processed in a method of our own
• Surface resistance 10⁵ to 10⁷ ohm
• Suitable for industrial laundry

Fit and size range

The coat is stocked in twelve sizes from 3XS to 6XL. That covers a mixed workforce without special orders, from a temporary hand in the test area to the shift supervisor. The oversizes from 3XL upwards run in the same cut and the same shade, so a repeat order fits the existing stock without a visible break.

Short sleeves suit warm production areas and stations where long sleeves get in the way, for example soldering benches, stereo microscopes and placement machines. Exact measurements per size are listed in the size chart in the Downloads tab of this product page.

Where black earns its place

Black is the pragmatic choice for areas with flux, solder paste, toner and grease. Those contaminants are mostly dark and barely register on black fabric. The visual condition of the garment stays presentable far longer, which is a practical argument for service technicians working at customer sites.

Black also has a limit. In cleanroom-adjacent zones where contamination should be visible, white is the better call, and cornflower blue works for marking whole teams. All three colours use the identical cut, so a mixed fleet of garments still looks consistent.

Technical data

Applications

• Hand soldering and touch-up benches in electronics manufacturing
• Rework and repair involving flux, solder paste and cleaning agents
• Toner and printer service plus equipment maintenance at customer sites
• Goods-in and storage of semiconductors and populated assemblies
• Test and measurement stations in multi-shift operation

Care and service life

The coat is designed for industrial laundry. The polyester share keeps cut and length stable across many cycles, and the conductive yarn does not lose its conductivity in the process. We deliberately quote no wash temperature here, the sewn-in care label in the garment is the binding source.

Finishing and custom versions

Embroidery and printing up to 160 °C are possible, and a sample print in advance is recommended. A press stud or pocket in a contrasting colour, a company logo and further equipment details are implemented on request, as are special colours outside the catalogue range. Ask us for a quotation.

Standards and testing

Dissipation and surface resistance were successfully tested to DIN EN 61340-5-1:2016 at STFI. The measured value is 10⁵ to 10⁷ ohm at 23 (±1) °C and 25 (±5) % relative humidity. No testing or certification to further ESD standards exists. The coat is one element of an EPA concept and replaces none of the other measures.
