Air Covered Yarn
Air Covered Yarn is a yarn that has a layer of polyester or other synthetic filament covering an elasthane core. This type of yarn is used to make fabric that combines the advantages of both spandex and traditional textiles. It is often used in lingerie, swimwear, knitted socks and sports fabrics. The process of producing this yarn is streamlined and uses less energy than traditional spinning methods. It also consumes less space than other types of yarn production.
The Air Covered Yarn manufacturing is an efficient process, the bare Spandex is intermingled with various filament yarns like Polyester or Nylon at regular intervals using compressed air that’s applied through a special network nozzle. This air jet machine is equipped with imported network nozzles that allows the elastane to be covered by different types of raw materials in an even manner.
Textile companies in India use HKV204 air-jet machine to produce air covered yarn with a capacity of upto 25 metric tonnes per day. The machine uses a high degree of mechatronics and is operated through PLC. It is also designed to meet the highest industrial standards.
This machine is capable of producing a wide range of yarns for many applications. It can be used for making knitted fabric, woven fabric, seamless underwear, sportswear, pantyhose and protective gears among others. The equipment is easy to operate and maintain. It also requires a lower level of maintenance than other machines, and its energy consumption is 25 percent less.
The HKV204 machine is also capable of producing both single and double covering mode. The single covering mode is the most popular choice. This type of machine is also known as a spandex covering yarn machine or cover yarn machine. This is because it covers a bare spandex with other yarns in order to add elasticity that normal textile yarn cannot offer. Usually a textile polyester / polyamide or nylon is used to cover the elasthane.
It is important to know that the air pressure in the nozzle affects the loop density and denier of the yarn. The higher the air pressure, the more loops are formed in a given length of yarn. This in turn results in the higher denier of the yarn. It is also important to understand that the air pressure affects the loop stability of the yarn. The lower the air pressure, the more stable the loops are.
It is also important to know that the amount of lycra and polyester content in the air covered yarn can be calculated by weighing 1 meter of the yarn and taking the weight after removing lycra from it. This will help you to determine the percentage of raw material that you need to purchase. It was found that the percentage of polyester and lycra content changes as air pressure increases after statistical analysis.
