What is the Difference Between Air Covered Yarn and Machine Covered Yarn?

Basically, the difference between an air covered yarn and a machine covered yarn is that the former is made up of continuous filaments of synthetic fibers, while the latter is a textile that has been processed using a texturizing process. Depending on the processing method, the yarn can either be opaque or transparent.

Rolags are a woolen spinning preparation.  Because of their structure, the fibers wrap and twist around each other and keep a core of air in the yarn.  This makes the yarn super wa…

Texturizing processes make yarns more opaque

Various texturizing processes are used to make yarns more opaque and to impart spun like qualities. The process is based on forming loops or crimps and heat setting the resulting fiber bundle.

In the context of texturizing, the most important property is that of opacity. This is achieved by making the individual fibres more parallel and reducing the diameter of the filaments. In addition, texturizing techniques make the color yarn smoother and less slippery. The effect is especially noticeable on finer yarns where the yarn is stretched by more than 400 percent.

Another advantage of texturing is that it enables the formation of coils. These loops can be false twisted to provide twisting torque. The effect is not only useful in protecting the yarn against abrasion, but also improves its rigidity and strength.

In addition to the draw-me-ocean, there are two other texturizing processes: air-jet texturizing and bulk continuous filament production. The first process uses overfed yarns, and the second involves heat set filament entanglements.

Core yarns are continuous-filament synthetic yarns

Basically, a Core yarn is a continuous-filament synthetic yarn that has been twisted into a multi-layered structure. It can be produced with a variety of methods.

A high tenacity nylon or polyester continuous filament is considered an ideal core. It can be combined with another fiber type to produce different properties. For example, a blend of polyester with polyamide will give a higher tenacity rating than a pure nylon or polyester.

During the manufacturing process, a texturizing machine can be used to give the yarn particular geometrical and surface properties. These yarns can be a functional alternative to petroleum oil based virgin continuous filament yarns.

These yarns are made from recycled plastics and can be a combination of recycled plastics, a core, and spun staple fibers surrounding the core. These yarns are available in many colors and thicknesses. They can be a great choice for apparel, baby blankets, and home decor like Polyester yarn and nylon yarn .

A corespun yarn is an extra compact yarn that is highly abrasion resistant and has a very good strength-to-weight ratio. It can also be used for technical applications.

Cost of air covered yarns vs machine covered yarns

Putting it in the context of a given, the air covered yarn may be a no brainer. Among other perks, the best part about the air covered yarn is that you get to see the entire product at one time. Hence, the air covered yarn is an ideal choice for your next upscale soiree.

The requisite amount of money to be spent can be a major factor, but it can be circumvented by utilizing a quality air covered yarn. A quality air covered yarn can last several cycles without a major overhaul. The air covered yarn is a worthy successor to the more traditional cotton and polyester counterparts, thanks to its patented design and proprietary fibers. Its superior quality is the reason for the name of the family. Moreover, a quality air covered yarn is also a boon for the wearer. The most popular and most common fiber used in air covered yarn is cotton, but a variety of other natural fibers are also used.

Coefficient of yarn friction in the knitting process

During the process of knitting, the coefficient of yarn friction varies depending on a number of factors. The material of the yarn, type of materials used, lubricants, dyeing processes and the atmospheric conditions are some of the factors that affect the final value of the friction coefficient. The pattern of the yarn, colour and cleanliness are also factors that influence the appearance of the knitted fabric.

The coefficient of yarn friction increases with increased moisture content. This is due to the occurrence of more loops in the same length of the air covered yarn. In addition, the binding points of the yarn become stronger as the air pressure increases. It also affects the denier of the yarn.

The fibre properties are also important in determining the strength of spliced yarn. The most important factor in splice strength is intermingling. Therefore, splicing can be a good way to eliminate problems associated with knots. It is functionally reliable and also retains the tensile strength of the yarn.
