Easy Cationic Dyeable Polyester for Textile Production 2.5Dx64mm (ECDP-Normal Temperature)

The 2.5D*64MM Normal - Temperature and Normal - Pressure Easy Cationic Dyeable Polyester is a kind of textile material with specific characteristics and advantages.

Fiber Dimensions

• Fineness: With a fineness of 2.5 denier (D), this staple fiber is relatively coarse. The larger diameter of 2.5D gives the fiber better strength and durability. It can withstand greater mechanical stress during textile processing and use, making it suitable for applications that require high - strength materials, such as in the production of heavy - duty fabrics and industrial textiles.
• Length: The length of the fiber is 64 millimeters (MM). This relatively long length is beneficial for improving the spinning efficiency and yarn quality. During the spinning process, the 64 - MM length allows for better fiber alignment and cohesion, resulting in yarns with fewer defects and higher strength. It also contributes to the smoothness and evenness of the fabric surface, enhancing the overall quality of the textile products.

Cationic Modification and Processing Conditions

• Cationic Modification: The fiber has undergone cationic modification, which means that cationic groups have been introduced into the polyester molecular structure through chemical treatment. This modification significantly improves the fiber's dye - ability. Cationic - modified polyester fibers have a strong affinity for cationic dyes, enabling vivid and fast coloring even under normal - temperature and normal - pressure conditions. This is in contrast to traditional polyester fibers that often require high - temperature and high - pressure dyeing processes. The cationic modification allows for more energy - efficient and environmentally - friendly dyeing operations, while also achieving excellent color fastness and a wide range of bright colors.
• Normal - Temperature and Normal - Pressure Processing: The ability to be dyed under normal - temperature and normal - pressure conditions is a significant advantage of this fiber. It not only simplifies the dyeing process but also reduces energy consumption and equipment requirements. This makes it more cost - effective and suitable for a variety of textile production lines. The fiber can maintain its physical and chemical properties during normal - temperature and normal - pressure dyeing, ensuring the quality and performance of the final products.

Performance and Applications

• Performance: In addition to its excellent dye - ability, the 2.5D*64MM normal - temperature and normal - pressure cationic - modified polyester staple fiber has good mechanical properties. It has high tensile strength, which enables it to resist stretching and deformation during use. The fiber also has good abrasion resistance, making the textile products made from it durable and able to withstand long - term use and washing. Moreover, it has good dimensional stability, maintaining its shape well under various environmental conditions.
• Applications: This type of fiber is widely used in the textile industry. It is commonly used in the production of fashion fabrics, such as those for making suits, jackets, and pants, where the ability to achieve rich and durable colors under normal - temperature and normal - pressure dyeing is highly valued. It is also suitable for home textiles, including curtains, tablecloths, and bedding, adding color and style to interior decorations. In the industrial field, it can be used to make conveyor belts, filter fabrics, and geotextiles, taking advantage of its high strength and durability.
