What is Colored Polyester DTY Yarn

Colored polyester DTY yarn is a special yarn made from blending white and colored polyester chips. It is a good alternative to natural fibers and has excellent durability and softness. It is suitable for knitting and weaving. It is also a good material for filter fabrics and automotive products.

It has a very soft texture, and it is easy to dye and wash. It is durable and resists a variety of chemicals. It can be used in a wide range of fabrics and applications, including curtains, bed sheets, pillows, blankets, and furniture.

This type of textured yarn is produced by deformation processing and crimping in an electric heating box. It changes the geometry of the original parallel and smooth filament into a fluffy, curled yarn with a soft feel.

The deformation of the twisted polyester yarn in an electric heating box reduces the internal stress and improves its elasticity and bulkiness. This process is also beneficial to the dimensional stability of the fiber. It is a good choice for the textile industry, especially for clothing fabrics, and for knitted and weaved materials with a low twist.

Textured yarn can be categorized into three different types: Low-, Semi- and High-Intermingle (knotted) strands. The low-intermingle strands are produced with the same diameter and a length of 0.5-1.0mm, whereas the semi-intermingle strands have a twisted shape and a width of 0.6-0.8mm.

These twisted yarns are usually produced in a full-dull luster, which makes them look more like cotton. They are often used in fabrics for shirts and suits, as well as lingerie.

They can be dyed in a number of colors and are usually packaged on paper bobbins. They are generally more expensive than other twisted yarns, but are a better option for producing fabrics that require special attention to wrinkling and dyeing.

In addition, they are also a good choice for fabrics with a high tensile strength, such as those made for automobile seat covers and luggage. They can also be used for making high-quality lace fabric.

There are several different deniers available for twisted polyester DTY, but the most common are low-, semi- and high-intermingle strands. These twisted yarns are often used in drapery and curtains, as well as for clothing.

The shrinkage rate of polyester DTY can be influenced by the processing selection and the quality level of the raw material. It is important to choose the right elongation at break and shrinkage in boiling water, because a higher elongation at break can produce stiff threads that decrease the shrinkage of the fiber and make it difficult to dye and finish.

Boiling water shrinkage is an important indicator of the dimensional stability and heat setting of the fiber. The smaller the shrinkage, the more stable the fiber is during processing and wearing, and the less likely it is to be damaged.

Moreover, the higher the crimping characteristic of textured yarn, the more flexible and comfortable it is. This is because textured yarns have an improved crimp elongation and crimp retraction, which increases the flexibility and comfort of the fabric.
