There are many "type" Polyester Embroidery Thread in the thread world. Some are for quilting some for decoration, some are used for splicing. Why are there so many types of threads available? Are there any generic threads for all projects?
Smooth fibers such as polyester embroidery threads, multi-filament polyester and rayon tend to have a higher gloss than non-smooth fibers such as cotton and polyester. However, even in this smooth fiber category, there are a lot of gloss or luster. High gloss is the result of a single micro-chain (the sewing thread is composed of many microfilaments). The shape of a single fiber determines how the light is reflected.
Filament refers to the chain of continuous, most means a lot. The threads are made of many long and continuous polyester embroidery threads, which are twisted together to produce the finished product lines we sew. So that each thread of the thread is rounded. The light reflects these small round fibers in such a way that the lines appear to be medium gloss.
The trilobite fibers have three different sides, so when the light strikes them, they reflect the light in a straightforward manner, resulting in a high glossy appearance. Although the shape of each microfiber is triangular, when the strands are stranded together to form the final thread, the final result is a smooth, round, high gloss line. Until recently, the three-leaf polyester fibers were weaker than ordinary round polyester fibers, so we had to choose strength and high gloss.
It is very good to use a different polyester embroidery thread on the spool with the top. The use of different weights is also very good. Bottom line than the top line. Most like to use a finer bottom line, because it is a good fusion, more can be wrapped around the spool. The most common bottom line is 50wt.
