Parameters and character

Features of Spandex Covered Yarn


1. Air-covered yarn (abbreviated as acy) is a yarn in which the outer fiber filament and spandex yarn are drawn through a certain type of nozzle at the same time, and the rhythmic network point is formed by the regular spray pressure of high-compressed air. The fabric feels soft and smooth;

2. Mechanical covered yarn (abbreviated as scy in English) is to continuously rotate and wrap the outer fiber filament on the core silk spandex that is drawn at a constant speed. It is twisted to have a twist (abbreviated as tpm in English) Flat and crisp style is its main feature.

Air-covered yarn and mechanical-covered yarn have their own advantages and disadvantages in downstream weaving mills. Air-covered yarn generally needs sizing when warping on an air-jet loom, otherwise the fabric is prone to fluff and broken threads, but it can be used directly by beating up. In terms of cost alone, the production capacity of air-covered yarn is much higher than that of mechanical-covered yarn, which makes the price lower than that of machine bag, which is convenient to reduce the cost of downstream weaving mills.

What is twist S and twist Z?


Recently, there has been a lot of talk about S twist and Z twist threads and it’s getting attention. Some refer to thread twist as a left or right twist, but the proper terminology is S or Z twist. When a sewing thread is constructed, it is made up of multiple strands, usually two or three strands (also referred to as plies or ply) twisted together, although some may have as many as six or eight strands twisted together. All sewing, embroidery, or quilting threads made for home machines, industrial machines, or longarm machines should have a final Z twist pattern.

The direction of the twist is important. If you hold the roving at one end and you twist it to the left, you create an “S” twist. If you twist it to the right, you create a “Z” twist

The initial twist (or first twist) for the individual strands should be an S twist. These strands are then twisted together in a final Z twist to form the thread. This is the same worldwide for any major brand of sewing, embroidery, or quilting machine. There are a few threads that have the opposite twist. Some hand quilting thread, knitting, and weaving threads have a final S twist. If you use a thread with an opposite twist, the thread will loosen instead of tighten as you sew with it. Threads are not marked with the twist pattern because it isn’t considered essential to know. If you use quality thread from a reliable company and stitch with it in its intended purpose, most likely it has the proper twist. If you notice that your thread unravels as it sews, it is probably a thread not intended for machine work.
