Analysis of Spandex Yarn, Spandex Yarn Raw Material Manufacturer

As a special fiber species, spandex yarn is a synthetic fiber with high elongation at break (above 400%), low modulus and high elastic recovery rate. Spandex yarn is generally not used alone, but mixed into fabrics in small amounts. This kind of fiber has both rubber properties and fiber properties. Most of them are used for core-spun yarns with spandex as the core yarn, called elastic core-spun yarns. The main characteristics of this yarn are that it can obtain good feel and appearance, The outer fiber composed of natural fibers has good hygroscopicity; the second is that only 1-10% spandex filament can be used to produce high-quality elastic yarn; the third is that the elastic percentage control ranges from 10% to 20%, which can be adjusted according to the use of the product , choose a different elasticity value.

There are also twisted yarns made of spandex nude silk and ammonia and other fibers, which are mainly used in various warp knitting, weft fabrics, woven fabrics and elastic fabrics.
1. Hydrogen Fiber Core-spun Yarn
Hydrogen fiber is used as the core yarn and the outer fiber comes from two components. The core-spun yarn fully reflects the respective characteristics of the core yarn and the outer fiber. It is a non-elastic staple fiber.
2. Covered Spandex Yarn
Covered spandex yarn with spandex as the core, non-elastic short fiber or chemical fiber filament in a spiral way to cover the elongated spandex yarn, without It is required that the core wire is completely covered, and there is a sense of dangling core in the stretched state.
Spandex covered yarn has two forms of covering:
Air-covered yarn (abbreviated as empty package, and the English box is written as ACV), is to draw the outsourcing fiber filament and fluorine feed yarn through a fixed guide nozzle at the same time, and form a rhythmic pattern by spraying high-compression air regularly. The yarn of the network point, the fabric feels soft and smooth; b. Mechanically covered yarn (abbreviated as machine bag, English dimension is written as SCV), is to rotate the outer fiber filament continuously and wrap it around the uniform draft The core silk spandex is twisted and has a twist (TPM in English). The fabric style is flat and wide is its main feature. It can be divided into single package and double package.
Sizing is generally required when the empty yarn is warped on the air-jet loom, otherwise the fabric is easy to fluff and break, but it can be used directly as knotted yarn. The output of empty bales is greater than that of machine bales, so the price is cheaper than machine bales.
3. Twisted Yarn
Twisted yarn also known as ply yarn, which is formed by merging and twisting two other inelastic yarns at the same time as chlorine fiber is drawn. Yarns have the same twist, which is the relationship between twisting and twisting each other. In the stretched state, there is a phenomenon of exposed core.
