ESD Men's Jacket long sleeve black, 155 g/m² cotton blend with conductive yarn - A1-ESD

Anyone equipping a rework or repair bench needs a jacket that stays on for eight hours without becoming a problem of its own. Flux residue and solder paste barely show on dark fabric, while the dissipative behaviour has to remain measurable. The black version is built around exactly that pair of demands.

The fabric weighs 155 g/m² and is made of 48 % cotton, 48 % polyester and 4 % conductive yarn. Cotton absorbs moisture and stays lint-free, polyester keeps front edges and sleeves in shape. The conductive yarn is woven into the cloth and therefore works across the whole surface of the garment, not only along a few seams.

Testing followed DIN EN 61340-5-1:2016 at the STFI institute and produced a surface resistance of 10⁵ to 10⁷ ohms. That places the jacket in the range an EPA concept expects from personnel-related dissipation.

Your benefits

• 155 g/m² across a full shift: The fabric weight sits between a light shirting and a heavy work jacket. Over eight hours at a soldering bench it traps far less heat than a dense synthetic coat.
• Concealed snap placket: The snaps sit behind a fabric strip. No exposed metal edge remains at the front, so nothing scrapes across a board when a technician leans over the assembly.
• Adjustable sleeve width: Snap fasteners at the cuff let the sleeve be taken in or let out. Close to the wrist for work under a stereo microscope, wider again for picking parts in the store.
• Sweat guard at the neck: An extra panel takes up moisture before it reaches the collar. The notched lapel keeps its line even when the jacket is worn daily and washed often.
• ESD logo where it is seen: The logo sits on the right side pocket. At the EPA entry check it can be read from several metres away, without anyone hunting for a label at the collar.
• Dark ground fabric: Flux, contact grease and toner dust leave no pale rings on black. Between two wash cycles the jacket stays presentable far longer than a light-coloured coat.
• Twelve sizes, one cut: 3XS through 6XL covers an entire shift. Agency staff, field service and permanent operators wear the same series with no break in colour or cut.

Material and fabric

The split of 48 % cotton, 48 % polyester and 4 % conductive yarn is a deliberate division of labour. Cotton handles moisture and gives the cloth a soft hand against the skin, polyester supplies dimensional stability so that front edges and cuffs do not go slack after many washes. At 155 g/m² the jacket stays light enough to be worn over ordinary clothing.

Compact cotton yarn is spun tighter than standard yarn, which leaves fewer fibre ends standing out of the yarn surface. The cloth barely pills and releases few particles into the room. On optical inspection benches and in placement that matters directly, because a single fibre on a lens or on freshly printed solder paste means rework.

• fabric weight 155 g/m²
• 48 % cotton, 48 % polyester, 4 % conductive yarn
• compact cotton yarn, lint-free and low in particles
• conductivity woven in, not applied as a finish
• suitable for industrial laundering

Construction in detail

The notched lapel collar gives the jacket a line that holds up in front of customers and auditors. It closes with a concealed snap placket, the snaps sitting behind the cloth. Nothing hard is left along the front edge that could scratch an assembly or a painted enclosure surface.

A patch chest pocket on the left takes a pen, a test record or a works ID. Two side pockets with slanted openings follow, and the angle means the hand finds them even while seated at a bench. The ESD logo is placed on the right side pocket, where it stays visible during normal work instead of hiding inside a collar label.

Lasting dissipation and wash resistance

Dissipative clothing is worth only as much as its condition after many wash cycles. Applied finishes lose their effect over time. Here conductivity belongs to the yarn construction, the conductive yarn is woven in and cannot be washed out. High-grade silver yarn is processed in a method developed in house.

The measured surface resistance is 10⁵ to 10⁷ ohms, recorded at the STFI institute at 23 (+/-1) °C and 25 (+/-5) % relative humidity. That low humidity is the demanding case, because dry air encourages charging. In an air-conditioned production area the jacket is therefore not working at the edge of its measured range.

Fit and size range

The jacket runs from 3XS to 6XL, twelve sizes from a single cut. A whole shift can be dressed without putting anyone into a garment that is clearly too large. Loose clothing catches on tool trolleys, rides up over the wrist strap and gets in the way during placement work, so the size range is a practical argument rather than a catalogue figure.

Exact measurements per size are listed in the size chart, available as a PDF in the Downloads tab of this product page. Before a larger first order, a sample set in two or three sizes is worth the effort. Anyone kitting out a whole department should include the outer sizes from the start, so that single items do not have to be chased later.

Why black in an ESD area

Black is the pragmatic choice wherever something sticks. Flux residue, solder paste, contact grease and toner dust leave visible rings on pale cloth and stay unnoticed far longer on a dark ground. For rework, service and printer maintenance that means longer wearing cycles between washes and fewer arguments about when a jacket needs replacing.

Technical data

Applications

• rework and repair benches with soldering stations, desoldering tools and flux
• manual assembly and touch-up work in board production
• test and measurement stations handling sensitive semiconductors
• goods receipt and component stores with ESD packaging
• field service work, worn over the technician's own clothing
• training rooms and visitor zones inside an EPA

Care and service life

The jacket is built for industrial laundering. The polyester share keeps collar, cuffs and front edges in shape, so the snap placket still closes cleanly after many cycles. Conductivity survives many wash cycles because it sits in the yarn rather than in a coating. Binding washing instructions are printed on the care label inside the garment.

Finishing and custom versions

Embroidery and printing are carried out in Germany. The fabric takes print up to 160 °C and suits embroidery, with a sample print recommended first. Available on request: a conductive rib cuff at the sleeve, additional snap fasteners or pockets, and a contrast version. Special colours outside the catalogue range are quoted on request as well.

Standards and testing

The jacket was tested for dissipative behaviour and surface resistance in line with DIN EN 61340-5-1:2016. The test institute is the STFI, and the measured value is 10⁵ to 10⁷ ohms at 23 (+/-1) °C and 25 (+/-5) % relative humidity. No testing or certification to further ESD standards has taken place.
