Title: Source for silk
Post by: Robert Zambelli on May 08, 2015, 10:09:15 PM
A few years back, I head about a place called Thai Silks.

Anyone ever deal with them?

Still in business?

Contact info?

  THANKS, Bob Z.

I've ordered from them two or three times.  Nice product and very good prices.  Get the 'China silk' .  It's www.thaisilks.com.

Dave: THANKS for link

I see the silks are rated at 4.5mm to 15mm - what does that mean?  Which is acceptable?  Would you just use RIT dye to get the color you want?

Denny I just took it on good advice to get the 8mm.  Seems about right. They have a fair slate of colors but I guess you could dye white if you wanted.  I had good luck shrinking red and blue but for some reason had fits trying to get the silver to pull up.  No non-tautening or light coat dopes here!!!

Thanks for the advice.
I was away from model aviation for a while but now I need to order the silk.

As I under stand it, the 8 mm, 12 mm, 5 mm etc refers to the number of threads per millimeter.  Sometimes you see it listed as 5 momo, etc.  8 mm is plenty tight enough weave for model planes.  5 mm is a tad loose and take much more dope. H^^


You have to consider the weights: example- 8mm silk per sq yard is 1.22 oz and 5mm silk would be .765 oz  per sq yard. Who knows the weight of dope per sq yard of difference????  n~

I bought some 5 mm & 8 mm.  The 5 is good for covering.  The 8 is too heavy for anything except reinforcement.

I buy from dharma. Go with the widest width offered to reduce scrap loss.

Hi gang,

Just for clarification on how silks are rated physically, here is the Wilipedia definition
of Momme:

     Mommes
Mommes (mm), traditionally used to measure silk fabrics, the weight in pounds of a piece of fabric if it were sized 45 inches by 100 yards (1.2 m by 90 m). One momme = 4.340 g/mē; 8 mommes is approximately 1 ounce per square yard or 35 g/mē.

The momme is based on the standard width of silk of 45 inches (1.2 m) wide (though silk is regularly produced in 55-inch (1.4 m) widths, and, uncommonly, in even larger widths).

     https://en.wikipedia.org/wiki/Units_of_textile_measurement#Momme

You will have to do your own calculations to *ounces per square yard*.  Eight Mommes is ~1 oz/ sq. yard, so you can extrapolate
from there to get approximate weights for other Mommes.

Good ole Wilipedia....it's knows everything.  Almost as smart as Google.

Cheers.

How does the 5mm weight conpare to the Easaki silk we have used? I think now Easaki only sells rhe tissue.  I only wish checkerboard pattern silk was available. Maybe there is a way to take white silk and have checker pattern added by silkscreening?

You can obtain some 6mm colored silk as other weights at http://www.thaisilks.com/

Umm, 6 millimeters is nearly 1/4". Isn't that a bit thick for covering a model?  Any idea how that is really measured? .06 might make sense.

I have tied both Thai and Dharma and a now solid Dharma customer

Funny how Bob resurrected his own two year old "silk thread"...a pun

I find the WEIGHT difference between 5 and 8MM to be a non issue....initially thinking the 5mm was better and lighter...but in practice the dope is where the weight gain comes... 8mm fills much quicker with less coats IMO

On a typical 36 to 60 inch wing the variance in just the silk weight is of no consequence.... only a few precious grams

In other words the physical weight diff between 5 and 8 is fractions ...but the tighter weave, slightly--- heavier 8mm, fills faster with less coats...

ONE MUST pay strict attention to the shrink bias... I bough 1 square yard once, and no easy way to see length 7~8% shrinkage vs width 1~2% shrinkage orientation...only buy min 2 yards at a time now
