|

Hello all,
I was reading the technical document about Tyvek on the Tyvek.com (http://www.tyvek.com/pdf/prod_techman.pdf) site today and it's really fantastic. (well as fantastic as a technical manual can be )
I found this tidbit about sewing... Type 10 is the "hard" Tyvek. (I have both 1056D (6.3 mm) and 1073D (7.6 mm) Tyvek but haven't tried this yet)

FOR TYPE 10 SPUNBONDED OLEFIN
• Use 3 to 5 stitches/in. (1.2 to 2 stitches/cm)
at low tension to eliminate skipping.
• Use #036 (Union Special) or #14 (Singer) needle,
or equivalent.
• Use a flat-tipped needle that cuts slit-like perforations.
“Rock Point” (Union Special) or “Narrow Wedge” (Singer)
will permit top-speed operation with the same thread
used for round-point needles.
• The informal industry standard of 25/4 tex (24/4 cc)
glacé thread of short staple cotton in #14 and #036
needles has given satisfactory performance in outdoor
banners when coupled with 16.5/3 tex (36/6 cc) soft
looper thread. If smaller diameter thread is required,
14.5/4 tex (40/4 cc) glacé thread of “Sak” quality
should provide satisfactory results.

Bill,
I was checking out old threads and ran across this one. Thanks for mentioning tyvek. I am constantly learning something new about this product. I just completed the Tyvek Friendship Shirone sail. I need to get pics posted on that thread. Maybe, tomorrow???
Talk to you soon,
