Advantages and disadvantages of covered silk yarn:
Advantages of covered silk yarn: It is an elastic yarn formed by covering the elongated spandex yarn with spandex yarn as the core, and non-elastic staple fiber or filament in a spiral manner. Its strength is higher than that of any single yarn. .
Disadvantages of covered silk yarn: it is easy to fluff and break the wire, and there is a phenomenon of exposed core under tension.

What are the characteristics of covered silk yarn?
When using covered silk yarn, its advantage is that it has good elasticity and can be stretched 5-8 times without aging. Spandex cannot be woven alone, and is generally woven together with other raw materials. The proportion of spandex is about 3-10%. During the period, the proportion of spandex in swimwear fabrics reached 20%. Therefore, the product is a synthetic fiber with high elongation at break (above 400%), low modulus, and high elastic recovery in use. The Chinese product name of covered silk yarn. Also known as elastic fiber. In addition, it also has high elongation (500%~700%), low elastic modulus (200% elongation, 0.04~0.12 g/denier) and high elastic recovery (200% elongation, 95%~ 99%). In addition to high strength, other physical and mechanical properties are very similar to natural latex silk. So what you need to know is that it is more resistant to chemical degradation than latex silk, has moderate thermal stability, and has a softening temperature above 200°C.
Due to its many advantages, it is used in the dyeing and finishing agents of most synthetic fibers and natural fibers, and is also suitable for the dyeing and finishing of covered silk yarn. covered silk yarn is resistant to sweat, sea water and all dry cleaning agents as well as most sunscreens. Prolonged exposure to sunlight or chlorine bleach will also fade, but the degree of fading varies with the type of spandex. So now it has more pronounced stretch because it's 3.8% spandex. Generally speaking, 2% spandex is very elastic. Due to the high proportion of viscose fiber, viscose itself has better moisture absorption performance, so the overall comfort and antistatic properties of the fabric are better. It is also mainly used in woven, elastic denim, webbing, socks, underwear, lace and sporting goods, etc. To sum up, the uniformity of evenness increases with the increase of twist. The twist is too small and the outer fibers are loose. During spinning, due to friction, etc., the fibers move slightly along the yarn axis, so evenness deteriorates.

covered silk yarn classified by spinning technology
(1) Yarn is classified according to spinning technology
Combed yarn: yarn spun by combing technology. Compared with carded yarn, it uses better materials, the fibers in the yarn are straight and parallel, the yarn quality is better, and the yarn fineness is finer.
Carded Yarn: Yarn spun by usual spinning techniques. Also called carded yarn, cotton spinning and wool spinning are slightly different.
(2) Yarn is divided according to dyeing and finishing
Primary color yarn: yarn that maintains the original color of the fiber without any dyeing and finishing processing.
Bleached yarn: yarn that has been bleached and has a whiter color. Usually refers to cotton yarn and hemp yarn.
Dyed yarn: yarn with various colors after dyeing.
Colored yarn: yarn spun from colored fibers.
Singeing yarn: Yarn with brighter appearance after singeing processing.
Mercerized yarn; mercerized yarn, including mercerized cotton yarn and mercerized wool yarn. Mercerized cotton yarn is treated with a certain concentration of lye to make the yarn have silky luster and high strength; mercerized wool yarn removes the scales of fibers in the wool yarn, and high-strength polyester sewing thread makes the yarn soft and gentle on the skin. Too much influence.
