Dyeable Cationic Polyester Fiber For Spinning 1.4D X 38mm CDP High Temperature

Cationic Dyeable Polyester for Spinning 1.4D x 38mm (CDP-High Temperature)

Fiber Dimensions

• Fineness: The fiber has a fineness of 1.4 denier (D). This moderate fineness provides a good balance between softness and strength. It is coarse enough to offer sufficient durability and resistance to wear and tear, yet fine enough to ensure a relatively smooth texture, making it suitable for a variety of textile applications.
• Length: With a length of 38 millimeters (MM), it is an ideal length for the spinning and subsequent textile manufacturing processes. The 38 - MM length allows for efficient fiber handling, enabling good fiber alignment and cohesion during spinning, which is crucial for producing high - quality yarns with consistent properties.

Cationic Modification and High - Temperature Resistance

• Cationic Modification: The fiber is cationically modified, which means that it has been chemically treated to introduce cationic groups onto the polyester molecular chain. This modification significantly changes the fiber's dye - uptake properties. Cationic modification makes the fiber more receptive to cationic dyes, allowing for more vivid and fast - coloring dyeing processes. It can achieve deep and bright colors that are difficult to obtain with unmodified polyester fibers, enhancing the aesthetic appeal and colorfastness of the final textile products.
• High - Temperature Resistance: This polyester staple fiber is designed to withstand high temperatures. It has excellent thermal stability, which is particularly important in various textile processing steps such as heat - setting and dyeing at high temperatures. The fiber can maintain its physical and chemical properties, including its shape, strength, and color - fastness, even when exposed to elevated temperatures. This high - temperature resistance ensures that the fiber can be processed under demanding conditions without compromising its quality, making it suitable for applications that require heat - resistant materials.

Performance and Applications

• Performance: In addition to its unique dye - ability and high - temperature resistance, the 1.4D*38MM high - temperature cationic modified polyester staple fiber has good mechanical properties. It possesses sufficient tensile strength to endure the mechanical forces involved in textile manufacturing, such as stretching, twisting, and weaving. The fiber also has good abrasion resistance, which contributes to the durability of the final textile products, allowing them to withstand regular use and washing.
• Applications: This type of fiber is widely used in the textile industry, especially in the production of fashion fabrics, home textiles, and industrial textiles. In the fashion industry, it is used to create vibrant - colored clothing items, such as trendy shirts, dresses, and sportswear, where the bright and long - lasting colors achieved through cationic dyeing can enhance the visual appeal of the garments. In home textiles, it is employed in the manufacturing of curtains, bedspreads, and upholstery fabrics, adding a touch of color and style to interior spaces. For industrial applications, it can be used in the production of filter fabrics, where its high - temperature resistance and good mechanical properties make it suitable for filtering high - temperature gases and liquids.
