Sounds like a ball of wool ! Wool is usually 2, 3 or 4 ply, and is sold in balls either by the ounce or gram.
Yes. A ply is a layer so 2 ply is double as strong as 1 ply
yes
My guess would be because a 2 ply paper towel has two layers instead of one.
1 ply, 2 ply,3 ply and i think 4 ply not sure. and there is the wash stuff, Cotton, normal, extra strength and a few others
The load range indicates the ply rating of the tire or the number of plys under the tread. A = 2 ply B = 4 ply C = 6 ply D = 8 ply E = 10 ply F = 12 ply G = 14 ply H = 16 ply J = 18 ply L = 20 ply M = 22 ply N = 24 ply This has a direct relation to the Load Index which tells you the weight the tire can carry. The more plys the more weight the tire can carry.
Polyester does a lot for the environment 1.)It is recycling 2.)It keeps you warm 3.)Anybody can buy polyester
It depends on the climate you are in. The best material for making a flag to hang outside in a climate where there is a lot of wind and rain is a polyester 2 ply blend. But if you live in an area where there is a lot of sun, nylon is preferred due to its fade resistant properties.
There are two meanings for 'ply' with wool. Some wool manufacturers use the term ply to describe the weight of the wool. A 2 ply is a very fine baby wool whereas a 16 ply is a chunky or heavy weight yarn. The other meaning is the number of threads the yarn consists of. For example to a hand spinner a 2 ply means a yarn that has two single threads 'plied' together to form one length of yarn.
2 ply, ply wood and mixed with a bit of oak for strenght
He invented the 2-ply toilet paper.
The difference between 8-ply and 4-ply wool, can depend on the weight of the plies. Some 3-ply yarns have heavy weight (fatter) plies, which knit up heavy worsted, where 2-ply lace weight yarn plies are much lighter (skinnier) plies that knit up very light/lacy/small.If I were to guess, the 8-ply in question, may have smaller plies than the 4-ply. I think if you double the 4-ply, that would be too much. You should try a gauge swatch using the 4-ply singularly, and maybe adust the needle size.
Your question doesn't make sense. For example: 4-ply yarn is 4 singles plied (twisted and set) together.Lace weight yarn is usually single or 2-ply.
