Humans are the biggest source of contamination in the cleanroom This is the reason why high quality cleanroom garments are absolutely essential for protection

of the product The following aspects should therefore be considered when

choosing garments:

technical features of the Cleanroom fabric wearing comfort and physiological characteristics garment construction, e.g the quality of the seams, the fitting etc

In order to have an optimal running “system of cleanroom garments” (chapter

1.3) it is necessary that all the individual demands on the cleanroom

gar-ments be checked with the requiregar-ments of the user at their workstation.

Only once this is done the filter between human and product can become effective

Trust in our competence

Making a decision as to which system gives an optimal solution for your

clean-room is not always easy For this reason we offer our extensive experience

within the field In order to provide the perfect solution for you, we have devised the following procedures to make the choice of appropriate products easier

Amongst them are:

Tests of fabrics under a standardised dastex procedure

Co-operation with independent institutes to prove our

quality standards

Assembly and continuous development of our own test cleanroom (Body-Box, chapter 1.3) including the ability

to test cleanroom products with the use of the Helmke-Drum-Method or the modified ASTM F51-68 test methods

Supply of technical data provided by the manufacturer Despatch of samples to our customers for in situ testing

Complete technical back-up from our in house experts

Links, via dastex, to a world-wide network of leading

cleanroom product manufacturers This grants our customers complete information for all quoted products, and a

high level of confidence whenever an order is placed.

IMPORTANT INFORMATION ABOUT CLEANROOM GARMENTS

Cleanroom garments – the most important filter between human and product

Due to a lack of standards and regulations for cleanroom products it is nearly impossible for end users to evaluate cleanroom garments on the basis of technical data sheets

There is also the problem that each of the product manufacturers will use a

different testing method.

This is why, in co-operation with a number of approved institutes, we have

developed our own standards to enable our clients an objective assessment

of all our cleanroom garments

Our aim is to make a realistic comparison of single products possible Hence the first and most important step is to equalise the starting condition:

Our most important cleanroom fabrics will be decontaminated 50 times

before testing to give realistic and practical results

Those samples will be tested by international approved and neutral textile

research institutes under equal conditions

The gathered data is then used by our expert technical team to provide

recommendations

For your guarantee of continuous quality the most important tests will be

repeated regularly by us

In the desire to continuously develop our cleanroom garments further in all areas,

dastex invested in 2004 / 2005 in an own test cabin, a so called Body-Box

In here whole garment systems, as well as single garment components, can be tested for their rates of particle shed

During the development, in co-operation with CCI – von Kahlden GmbH, greatest importance was placed in the highest possible reproducibility of the test results

Beside the Body-Box (in accordance with IEST-RP-CC003.3) a cleanroom cabin was installed, which includes a special test bench to evaluate rest contamination in accordance to modified ASTM F51-68 Additionally, a Helmke-Drum was added to the existing equipment

A filter testbench for the determination of the particle retention capacity for air-borne particles is also an important part of the test set-up

The garments must be prepared according to the applications within cleanrooms

For projects with extra demands on your cleanroom garments we offer textiles

with special finishing.

For some of our fabrics the following options are available:

Water repellent finish Anti microbiological finish 1

Hydrophilic finish

In addition we supply the Cleanroom fabric ION-NOSTAT BS which is, according

to the manufacturer, “flame resistant“ class “Index 1” according to EN533

classified

1 As part of the discussion “is an anti microbiological finish in cleanroom garments in the sterile area worthwhile or a waste?“

see also the article in the trade magazine “Reinraumtechnik“ Vol 1/2006 (GIT publishing).

Nano finish for cleanroom garments

The finishing of cleanroom garments with nano particles is still in the early stages but initial tests have been quite successful

A ‘dirt resistant’ Nano finish for cleanroom garments is already available

Certain work processes require not just product protection also the protection of the employee for risks as varied as flame and cut protection In these cases

dastex will work to develop a bespoke solution with the user based on his

parti-cular requirements Our own prior experimentation in completed special projects help in the consultation process and can help to simplify the search for particular solutions

ESD / EPA – FABRIC / GARMENT

Our already extensive choice of cleanroom garments also has additions in the area

of ESD/EPA garments Quite a few of our existing cleanroom garments (such as ION-NOSTAT-VI.2, ION-NOSTAT Plus, etc.) already fulfil typical ESD demands There are circumstances within certain limit ranges, e.g where cleanroom demands are mainly judged as low (or where possibly no criteria exist) where higher air perme-able fabrics are used (also so called “mixed fabrics”)

Dastex can offer you a choice of products to cover these options.

1 Nomex filament fabric for cleanroom use

2 ESD coat

3 Fabric and coat tested at STFI and certified according to EN61340-5-1
