TexCare liquid Laundry Detergent For Shielding Textiles With Silver Or Stainless Steel Threads.

Special recipe detergent preserves the shielding performance, saves the environment and is suitable for many allergy sufferers.

After many years of experience with shielding fabrics we found out that some laundry detergents are bad for the shielding attenuation. In addition, customers who suffer from MCS (Multiple Chemical Sensitivity syndrome) reported some brands cause an undesirable odor. This new laundry detergent, developed in cooperation with a prestigious manufacturer of eco-detergents, will not react with our Silver or stainless steel shielding fabrics which are washable.

It contains no fragrances, coloring agents, complexing agents, preservatives, enzymes, genetic engineering, petrochemicals, and all ingredients are 100 % biodegradable.

1 liter is enough for 20 loads. The dosage is independent of the water hardness. Pour 50 ml TEXCARE per load in the detergent drawer or put it straight in the drum. Select delicate cycle with washing at 30°C. Can also be used for hand washing. Please take note of the fabric care label, respective to washability, ironing and drying!

TexCare powder Soap from rapeseed oil 5-15%, sugar surfactant 5-15%, coconut oil alcohol sulphate 5-15%, vegetable alcohol (ethanol) 1-5%, sulphated castor oil <1%, citrate <1%, water up to 100%.

Great Way to Connect Leads to a Conductive Fabric

Working without alligator clips or snaps? This nontoxic, solvent free and water soluble material spreads easily and dries quickly to form a conductive bond between most surfaces. Just squeeze a little bit onto your fabric, embed the bare copper wire lead into it and wait about an hour. It adheres well to a wide range of synthetic and natural fabrics. Note that Electric Paint is water soluble, washing with soap and water will remove any paint which has been applied. If you want to make it more durable, you can use waterproofing spray to protect the surface of the fabric. Use it to make conductive traces, repair circuit boards, even make smart textiles!

The paint's conductive properties do not degrade over time. In-house samples demonstrate that the material can last years if treated properly and kept dry. Electric Paint is well suited for screen-printing with meshes ranging from 43t to 90t. The paint is slightly resistive- at approximately 55 ohms per square. The conductivity of Electric Paint increases as it dries, therefore wait until it is completely dry to test your projects. 10ml squeeze tube. Black.

Grounding Cord Need a ground cord?
12-foot long ground cord, alligator clip on one end bites onto fabric, 3-prong-style plug on the other end plugs easily into your grounded outlet. Only the round lug is connected to the wire. The 2 flat prongs are not connected to anything.

Alligator Clips

Attaches Ground Cords to Fabric or Plastic

Want a tidy and good looking way to attach a ground cord to a conductive fabric or plastic shield? This simple hardware combination does the trick in style. First, crimp the provided ring terminal to your ground wire. Next, punch a small hole in your conductive sheet. Pass the stud of the snap through this hole and through the ring terminal. Finally, apply the other half of the snap. Makes good contact and you can move it or remove it as needed. Snap is nickel plated for excellent corrosion resistance and is washable. Ground wire not included.

What Kind of Unit is "Ohms per Square"?

Surface resistivity is measured in Ohms per square (Ohm/square). Ohms are units of resistance, but what about the square?

Engineers know that you can measure surface resistivity from one point on the surface to another using an ordinary ohm-meter. Then the units would be Ohms per distance between points or Ohm/m. But this method yields very inconsistent results, especially with surfaces that are not perfectly homogeneous.

More consistent results are obtained by measuring the surface resistivity between two bars. For simplicity, two parallel bars of equal length are placed exactly 1 length apart on the surface to be measured. They form two opposite side of a square. It doesn't matter how long the bars are, since longer bars will be placed proportionally further apart. The resistance measured between the two bars in Ohms is the resistivity of the surface in Ohms per square! Surface Resistivity Meter

A note about washing shielded fabric:

Please note that some shielding fabrics are not washable at all, and some can be hand washed only. Please read and follow washing instructions that come with your product.

Poor water quality will damage Silver.
In particular Sulphur, high Fluoride, and low pH will react strongly with Silver and destroy conductivity and shielding performance.

Test your tap water on a small fabric swatch before washing your fabric/garment:
    1- soak a small fabric swatch in tap water for 1 hour.
    2- look for color change in the water or swatch, especially blackening.
    3- air dry the swatch and check for conductivity (by touching an Ohm meter to 2 points on the fabric)

If color change or loss of conductivity occurs, DO NOT use tap water to wash/rinse your fabric. Use distilled or deionized, reverse osmosis water.

Use Texcare to help protect the Silver in the shielding fabric. Washing will eventually degrade all fabrics with Silver fibers and reduce shielding performance. Discoloration over time is normal.

Keep conductive fabrics away from electrical sockets and bare wires! Fabrics do not contain flame retardant, use caution around open flames and heat sources.
Note: Except for full roll orders, fabrics are folded for shipping.
If you require un-creased materials for your application, please add the "roll charge" option and we will ship your fabric rolled on a core.
There is a $10 roll charge.

Sorry, no returns on cut goods. See Return Policy

Minors defects (such as small pulls, small holes, or minor discolorations) are a natural part of the production of these high tech fabrics.
Manufacturers allow defects up to 1% of the area of the fabric. We find that actual defects are much less than that, but are impossible to avoid entirely.

A note about EMF Blocking or EMF Shielding Fabrics: Many of our EMF* shielding fabrics will work well to shield electric fields and/or radio frequencies. We make an effort to avoid saying our fabrics will block emf's. Blocking suggests 100% shielding, which in most cases is not possible. It would be incorrect for us to state 100% shielding, even if a material is rated for 99.9999% or better (which some of them are). Even an 'airtight' balloon will eventually go flat due to leakage.
* When it comes to emf shielding fabrics, it is better to be more specific and to state how well the fabric shields radio frequencies or how well the fabric shields electric fields. Both of these fields are considered emf. Emf can also be used to refer to magnetic fields, which cannot be shielded by fabrics. Magnetic field (guass) shielding, requires the use of solid metal magnetic shielding alloys.
