Where are Tech
Wear garments made?
All
Tech Wear garments (standard-stock and custom-made) are made with
pride in North Dakota from fabric milled in North
Carolina. The Angelica garments we now offer were once made in Mexico and Costa
Rica, but are now also being made in North Dakota.

Why do some garments have cords hanging from the wearer's hip?
Garments
with ground cords are
groundable garments or ground-monitorable garments. Our garments fight
static in the following three levels:
SHIELDING: static shielding garments provide a barrier
between static charges generated on personal clothing and static-sensitive
components.
The carbon web of the garment ensures even dissipation across the garment's
entire surface, greatly reducing the likelihood of damage from ESD or concentrated fields. Static shielding garments do not, however, ground
the operator or garment.
Some popular examples of Static Shielding Garments: LEQ-13
& LEQ-43 |
LOC-13 |
LOJ-33 | VOJ-23
| SOJ-23
GROUNDING: Our groundable
garments provide a path to ground for
both operator and garment through a single connection at either side
of the
wearer's waist. Conductivity between operator and garment are
ensured either by the grid-knit ESD cuffs or with the Key
Option and existing wrist straps. If you're
currently using wrist straps, you probably already know how effective personnel
grounding is; imagine those benefits with the added benefits of unleashed
hands!

| VOJ-23C
| HOJ-33C
| HOC-23C
| HIJ-43C
| LOC-23Key
| LOJ-23Key
MONITORING: Our X2 garments are compatible with dual-loop ground monitors for applications when ensuring absolute grounding is
critical. The instant either garment or body aren't grounded, the monitor beeps--a simple but very effective way to
eliminate yield losses.
See the X2-HOJ-23C.
We can make the X2 in other styles, fabrics and colors.
What custom options are available on a garment?
Access Pockets - which allow access to the
pockets of your street clothes underneath our knee-length coat.
ESD Grid-Knit Cuffs - which form contact
patches on both wrists to ground the body. All garments with ESD
Cuffs also include 4mm male snaps at the wearer's waist to snap the ground cord.
Elasticized Sleeves - We can install elastic
at the sleeves if grounding is not required, but loose-hanging sleeves is a
concern.
Neckline Labels - For garment identification
purposes, we can sew a custom label to the neck or almost anywhere inside the
garment.
Modified Length - Jacket-length too
long? Coat-length not long enough? Just tell us how long you want it
and we'll make it happen!
Modified Sleeve Length - From short-sleeves to
gorilla-arms...yes, we can!
Overcuffs - we can install an elasticized
layer of fabric over the standard ESD grid-knit cuffs.
Patches - mail us your name/company logo
patches for installation or email
us the image of your logo and
we'll take care of the rest.
Pen-Tabs - a handy place for stashing a ball point
pen, we can install them almost anywhere on the garment.
Side Slits - do you require a full-length coat, but do a lot
of sitting and getting-up at work? Side slits are the answer!
Unexposed Snap Front - the snap backings
at the front of the garment can be installed under a layer of fabric for
situations where scratching sensitive surfaces is a concern.
Do you make anything besides garments?
Yes! We also make groundable or static-dissipative chair covers to your
specifications. They are available in all fabrics and colors and can be
grounded with a drag chain and existing ESD flooring. In addition, we will
also make custom covers to suit almost any application. We've made ESD
covers for electronic production assembly carts, microscopes, even ESD curtains
for shelves used for static sensitive components.
We also offer ESD barbeque aprons, cobbler aprons and sleeve protectors for
static shielding or grounding. Email
us with your application and we'll reply with a solution.
Are your garments suitable for cleanroom use?
No. But our sister company, TW
Clean produces groundable Class 100 cleanroom bunnysuits. Tech
Wear garments are intended primarily for sensitive electronics production
environments, but are not really intended for wear in cleanrooms.
Are your garments suitable for working around high voltage hazards?
No! Tech Wear garments are made to protect sensitive electronics from the
voltage generated by the operator's body and clothing. They are highly
conductive and should not be worn near sources of high voltage. Hopefully
there are no high voltage hazards in your ESD-safe workplace! Please contact
us for a copy of ESD Controls in Hazardous High Voltage
Environments, a paper that discusses an approach to resolve the seeming
incompatibility of ESD controls and high voltage hazard safety controls.
How do you know if a garment is working?
The fail-safe way is to closely monitor and compare your product yields or reject
rates, before and after implementing our garments. For more immediate
certainty, test your garments following the guidelines in the ESDA's
[Standard Test Method] STM2.1-1997 - for the Protection of Electrostatic
Discharge Susceptible Items - Garments. You can either contact one
of our helpful reps
in your region, contact
us directly with your questions, or order your own copy of
STM2.1-1997 from the National
ESD Assocation in Rome, NY, (315) 339-6937. There are several local area chapters of the ESDA around the country.
Call for more information about activities and membership in your area.
Tech Wear can arrange to have a sample of your present garments tested
under our "No-Charge" Garment Testing Program.
Can you embroider or silkscreen
my name and company logo onto a garment?
Yes we can! In order to ensure a garment is as conductive as possible, the
preferred method is to embroider or silkscreen your name or company onto a patch
and sew this directly to the garment, but we can, depending on your fabric
selection, embroider or silkscreen directly onto the garment. Please contact
us with your questions and requirements.
What's the difference between the
various fabrics?
Each of the static control fabrics we use in our garments have a distinctive
advantage when matched to your application. Please E-mail
us with your requirements and we will explain the advantages of each.
| Fabric | Carbon | Polyester | Cotton | Fabric Weight | Groundable | ESDA STM 2.1 Guaranteed | Application |
| OFX-100 | 13% | 87% | - | 2.3oz/yd | YES | 100 washes | Groundable fabric when used in conjunction with cuffs or Key Option. Lightweight comfort and excellent ESD performance |
| IVX-400 | 7% | 93% | - | 4 oz/yd | YES | 100 washes | Groundable fabric when used in conjunction with cuffs or Key Option. Med-weight comfort, Excellent ESD performance |
| ECX-500 | 2% | 98% | - | 3 oz/yd | no | 100 washes | Static shield, Very Good ESD performance |
| Nylostat | 1% | 65% | 34% | 5 oz/yd | no | no | Heavy soil & solder, Good ESD performance |
OFX-100 is a light-weight knit (2.3 oz per square yard) fabric that is breathable, groundable and easily laundered. It is ideal for use in areas where there is little abrasion, light soil, and little or no exposure to soldering and chemicals. The fabric is made from monofilament thread, eliminating contamination from loose fibers working their way out of the fabric. The conductive grid pattern is knit into the fabric and designed to provide the highest carbon content and therefore best shielding and grounding performance available. Tech Wear's ESD knit cuffs can be added to any OFX-100 garment and allow grounding of garment and wearer through one single ground cord, without the need of a wrist strap. OFX-100 fabric is available in White, Blue, Burgundy and Teal. Click here to see available colors.
IVX-400 has the same excellent static control properties and performance as OFX-100, but is a slightly heavier and more durable weave. IVX-400 fabric is 4 oz per square yard; while OFX-100 fabric is slightly transparent (you can almost read a newspaper through it in a bright room), the IVX-400 fabric is denser and more durable. IVX-400 also repels soil, stands up to abrasion, and will not slough off fiber contaminants. Our ESD knit cuff option on a garment made of IVX-400 gives the wearer the advantage of garment and wearer grounding without the need of a cumbersome wrist strap. IVX-400 is available in White, Royal Blue, Green, NASA Blue, Teal and Burgundy. Click here to see available colors.
ECX-500 fabric is the best choice for effective yet economical static shielding garments. ECX-500 is used exclusively in the manufacturing of Econo$hieldTM garments, which are designed to give static control protection in areas where ESD sensitivity is important and when handling products with a sensitivity threshold above 2,000 volts. It is strongly recommended that when handling products below this level that the garment be grounded (OFX-100 or IVX-400). ECX-500 is available in White or Blue. Click here to see available colors.
Nylostat is a very durable woven fabric that works well for protecting personal clothing from heavy solder and soil, and where static discharge needs to be controlled. While Nylostat is composed of 34% cotton, its heavy weave can be warm in workplaces without airconditioning. We recommend Nylostat for heavy industry and for less ESD-sensitive applications.
Are the garments flame retardant?
All Tech Wear garments meet the federal standard for FR
(flammability retarding) requirements for
polyester fabrics, except sleepwear. The glass transition rate
(i.e. melting temperature) is
450 degrees F and the flash point (combusting temperature) is 720 degrees F.
Will solder splash melt
the fabric?
A hot soldering iron or a large drop of solder will cause some
melting damage to these fabrics, but they will not support a flame. Due to its dense weave of polyester and cotton,
Nylostat
tends to stand up to hot solder drops.
Where do you ship the garments
from? Where is FOB?
All Tech Wear garments are
made with pride in the U.S. from fabric knit or woven also in the U.S. FOB point is Minot, ND.
Do the garments ground the body
as well as a wrist strap? What if we're already using wrist-straps or heel straps?
Even better! While a single wrist-strap is adequate for grounding a body,
a grounded Tech Wear garment forms a conductive contact patch on both
wrists.
Even more significantly, wrist straps, heel grounders, and other items that ground the body do little
or nothing to protect from the static charges
caused by the tribocharging of personal clothing. A human body
grounded with a wrist strap wearing common street clothes becomes in this case, the
grounded eye of an
electrostatic storm.
If you're already using wrist straps and cost is an issue, check out our Key
Option garments, which use existing wrist straps to ground both the body and the
garment.
In addition to the benefit of freeing the operator's hands from the ground cord,
grounding the body through the garment also means fewer disconnects: an
operator's trunk is almost always less dynamic than his hands and the garment
affords some "give" rather than disconnecting from the ground cord.
What is the Key Option?
The Key Option refers to a special feature available on any Tech Wear OFX-100 or IVX-400 garment. The Key Option allows the wearer to connect a wrist strap directly to either sleeve hem of the garment and then connect a standard ground cord to a ground snap on a lower hip pocket for grounding the garment and the wearer through one grounding path, allowing for untethered arms. This provides an excellent mechanism for testing the grounding of the garment and wearer through the use of a standard wrist strap tester. This garment option is also compatible with continuous monitoring systems with one path to ground. |
Standard wrist strap connects to a 4mm female snap on the inside of the sleeve.
Standard ground cord connects to 4mm male ground snap on lower hip pocket. |

How should the garments be
laundered?
Tech Wear static control garments can be laundered at home or by a commercial
laundry service provider with excellent results. Laundering instructions
are printed on the size label at the back of the neck of each garment.

How long are Tech Wear garments
guaranteed?
All Tech Wear garments made of OFX-100and
IVX-400
fabrics are guaranteed to retain their ESD protection properties, in accordance
with the guidelines of the National
ESD Association's Standard Test Method 2.1-1997, for a minimum of 100
washings or 2 years, whichever comes first.
How long does it take to get
garments?

What is meant by sleeve-to-sleeve? What do Tech Wear garments cost?
What about pricing? What are X2 garments? What does ESD stand for? How do the garments work?
We will will be happy to furnish you with fabric samples for destructive
testing that can help you determine which fabric will work best in your work
environment. E-mail us
and we'll get them to you right away.
Contrary to some claims, fabric surface
conductivity alone is not enough. For a garment to truly
protect your product from body-borne static, conductivity across all
garment panels must be ensured. Unless the individual panels are electrically connected through
the seams, the garment cannot be grounded as a whole through one single
grounding point.

Sleeve-to-sleeve has become the abbreviated term referring to the
resistance measurement from one sleeve to the other on a static
control garment. The less resistance across a static shielding
garment's
seams and fabric, the more evenly it will dissipate charge
imbalances; more crucially in the case of groundable garments, the
more surely the body and garment are both completely grounded. The
method for testing a garment's sleeve-to-sleeve conductivity is fully described in the
National ESD Association's STM2.1-1997 for the Protection of Electrostatic
Discharge Susceptible Items Garments.
Please contact one of our helpful
distributors for pricing.
X2 Garments like the X2-HOJ-23C
are used with Ground Monitors that sound an alarm whenever the operator's body
is no longer connected to ground. (Click

Electro-Static Discharge. The seemingly
insignificant static charge generated by our own bodies and clothing
causes losses in the billions in our industry every year.
Naturally-occurring body-borne static electricity is an hazard to delicate electronic
components that you don't even have to
touch a microchip to destroy it.
