Standards for Reviewing Conductive Thread

Facebooktwittergoogle_plusredditlinkedintumblrmailFacebooktwittergoogle_plusredditlinkedintumblrmail

 
The following standards are used by The eTextile Lounge for testing conductive thread samples:

THREE RESISTANCE TESTS

  • hand sewn 8” trace
  • machine sewn top thread 8” trace
  • machine sewn bottom thread 8” trace

THREAD QUALITY

  • fray and whisker
  • ease of threading needle
  • ease of sewing
  • packaging

RECOMMENDATIONS
Listed according to conductivity, resistance, and quality.

MANUFACTURER or RETAIL LISTING
If available – information on manufacturer and/or retail outlet.
 

TESTING METHODS and MATERIALS

All LED circuits are sewn on a cotton broad cloth with felt backing.

Positive and negative traces are 8 inches long.

A size 24 John James crewel needle is used to hand sew the LED circuit.

Hand sewn conductive traces use a basic running stitch.
Machine sewn traces are 8″ and sewn on a Bernina 180 standard factory settings.
Conductive Thread Comparisons
 

A 1.8mm blue LED is hand sewn in place with 4 tight loops around the LED leads.

These testing standards were adopted February 2014 and will be used for all future conductive thread comparisons.
