Depth of mattress is usually 40cm
Single yarn = softness 120 thread count
Higher the count, the finer the thread
Shirt yarn - thread count = 40-80
Jeans yarn - thread count = 7-10
Double yarn = 2 single yarns twisted together for strength = shirt or jeans yarn
Have you wondered why thread gets thinner as the weight or thread size number gets larger? It is confusing but there is a reason behind this system. Here is a simple analogy to illustrate why:
The goal is to determine how much thread it takes to weigh one pound.
Thread A takes 20 miles to weigh a pound so it is labeled as 20 wt.
Thread B takes 40 miles to weight a pound and is labeled 40 wt. It is a finer thread because it takes 40 miles to weigh one pound.
Thread C takes 60 miles to weigh a pound so it is even finer yet.
There are two main types of monofilament threads: nylon and polyester. Traditionally, most monofilament thread has been nylon. Nylon is strong but it has some negative properties for sewing thread. It tends to go brittle over time, discolors (yellows), and has low heat tolerance. Nylon melts at approximately 400 degrees F. Although most irons do not have a numerical temperature setting, many irons can melt nylon when set at medium or high heat.
The preferred material for monofilament thread is polyester. Polyester does not discolor, go brittle, or have a low melting point. Polyester melts at the 480 to 510 degree Fahrenheit range and most irons stay well below this temperature up to the medium heat setting.
Our MonoPoly monofilament invisible thread is 100% polyester, thus the name, Monofilament Polyester.
Another caution: Watch out for monofilament threads labeled as 100% Polyamide. That may lead us to believe it is polyester but polyamide is the chemical word for nylon. Dishonest labeling? No. Misleading? Yes.
Be safe and stay with polyester when using monofilament threads.
THE TWISTED TRUTH Recently there has been a lot of talk about the way threads are twisted. Some refer to the twist as a right or left twist, but the proper terminology is S or Z twist. All sewing, embroidery, and quilting thread made for home machines, standard industrial sewing machines, and longarm machines should have a final Z twist pattern.
Twisted threads are made up of multiple strands or plies, usually two or three strands twisted together. On thread made for machines, the primary twist, or the twist on the individual strands or plies of thread, are made with an S twist. These strands are then twisted together in a final Z twist pattern to form the thread.
There are threads that have the opposite twist. Some hand quilting, knitting, and weaving threads have a final S twist. If you use a thread with an opposite twist (final S twist) in a machine, the thread will loosen instead of tighten as you sew with it. Threads are not marked with the twist pattern. If you use quality thread from a reliable company and use it for its intended purpose, most likely it has the proper twist.
1 cup salt
2 cups white vinegar
Stir until dissolved
put fabric in and soak (no time given)
Take out and hand in the sun to dry
The chemical reaction with the sun sets the dye
Vinegar also takes out creases
