ESD polo shirt short sleeve red, 180 gsm piqué with conductive yarn - A1-ESD

Some roles have to be recognisable from a distance. The floater moving between three lines, the maintenance technician, the person walking a visitor group through the EPA. Anyone working in red is found immediately in a hall full of dark clothing, and in an urgent case that saves minutes.

Red here is an internal code colour and not high visibility protective clothing. What the polo demonstrably does is dissipate: 4 % conductive yarn in the piqué carries the wearer's charge away before it discharges into an assembly. Around 100 volts is enough to damage sensitive semiconductor structures for good.

With red, dyeing is the real quality question. Reactive dyed cotton binds the dye chemically, so the shade stays strong instead of drifting towards pink or brick after half a year of laundering.

Your benefits

• Recognisable across the hall: Against dark workwear red stands out furthest. For floaters, maintenance staff or training leads it means colleagues can address them without a search.
• Colour depth from reactive dyeing: Red loses saturation faster in industrial laundering than any other shade. Binding the dye chemically to the cotton fibre is the effective answer to exactly that.
• Conductive rib knit collar: Knitted from conductive yarn, the collar holds skin contact at the neck. It sits close enough not to lift away from the nape when the wearer leans over a board.
• 96 % cotton, 4 % conductive yarn: Compact cotton charges less and sheds less lint than synthetics. The conductive yarn is knitted in, so it belongs to the material and not to a surface layer.
• Measured 10⁵ to 10⁸ ohms: STFI determined the surface resistance at 23 °C and 25 % relative humidity, that is under the dry conditions in which charging occurs most readily.
• Chest pocket for paperwork: Route card, pen or badge sit ready on the left chest. Anyone moving between workstations all day reaches them faster there than in a trouser pocket.
• Twelve sizes for mixed teams: From 3XS to 6XL even a group with widely differing builds can be equipped completely in the same signal colour, so nobody in the role ends up wearing a different one.

Material and fabric

The polo is made of 96 % compact cotton and 4 % conductive yarn, knitted as a fine piqué at 180 gsm. The cotton is ring spun, which produces a smooth yarn surface with few protruding fibres. The result is a knit that sheds very little lint and therefore releases few particles inside an EPA.

Cotton remains the default in electronics manufacturing for a plain reason. It charges less on its own than synthetics and smells less sharp after eight hours. A weight of 180 gsm is the compromise between a shirt still wearable in a warm hall and one that does not look thinned out after fifty wash cycles.

• 96 % cotton, 4 % conductive yarn
• 180 gsm fine piqué
• Ring spun yarn, smooth and dimensionally stable
• Reactive dyed for depth in the red range
• Low lint and low odour

Construction in detail

The collar is a rib knit made from conductive yarn and therefore part of the function. Rib knit contracts again after opening, so the collar does not end up lying on the collarbone after a few months. The three button placket is cut to let the polo pass over the head without pulling, with colour matched buttons in the placket.

On the inside a colour matched neck tape covers the shoulder seam. It keeps the neckline in shape and prevents chafing at the nape. The patch chest pocket sits on the left, the ESD logo on the left sleeve, where it stays visible even while seated at a bench.

Dissipation and wash resistance

As the conductive component a silver yarn is processed in a method developed specifically for this fabric. For daily use the consequence matters more than the method: dissipation depends on the yarn inside the knit and is retained after repeated washing and wear.

A garment in a signal colour is worn more often than the rest of the fleet because it is tied to a fixed role. Whether colour and conductivity hold up together across many wash cycles therefore decides the service life of the batch directly, and with it how often the same shade has to be reordered.

Fit and size range

The model runs in twelve sizes from 3XS to 6XL, so even a group of very different builds can be dressed entirely in red without anyone having to fall back on a different colour. Cut and shade stay the same right across the size range, so a single order covers the whole team without a second supply line.

The size chart is available as a PDF in the Downloads tab of this product page. It is the binding reference, because polo cuts differ from range to range and a look at the table avoids returns caused by wrong sizes, which are tedious to handle once garments have been decorated.

Red as role marking

Red works wherever a function has to be found quickly or a person is meant to stand out on purpose. Common assignments are floaters and maintenance, training leads, repair reception and the loan pool for visitors who enter an EPA only briefly. The distinction stays important: this is an internal code colour and not tested high visibility clothing.

Technical data

Applications

• Floater roles covering several production lines
• Maintenance and fault clearing inside the EPA
• Training, instruction and plant tours
• Repair reception and service counters
• Loan garments for visitors spending a short time in the EPA

Care and service life

Suitable for commercial laundering. Reactive dyeing is the decisive point with red, because this part of the spectrum otherwise fades fastest, while ring spun yarn keeps collar and hem in shape. Conductivity is retained over many washing and wearing cycles. The sewn in label carries the binding instructions.

Finishing and custom versions

The knit takes print up to 160 °C and suits embroidery, with a sample print recommended beforehand, particularly on a saturated ground. Decoration is carried out in Germany. Equipment on request: sleeves with conductive knitted cuffs, a contrast execution, long sleeve with conductive rib cuffs. Special colours are equally available on request.

Standards and testing

The model was tested at STFI to DIN EN 61340-5-1:2016 for dissipation and surface resistance and passed. The measured range is 10⁵ to 10⁸ ohms at 23 +/- 1 °C and 25 +/- 5 % relative humidity. No further ESD standards have been tested, and no suitability as high visibility clothing is claimed.
