Black Virgin Polyester Staple Fibre for Non-Woven Fabric 1.2Dx38mm (DDB)
The 1.2D x 38mm black polyester staple fiber is a remarkable synthetic fiber that plays a crucial role in diverse textile applications.
Fineness and Length
- Fineness: With a fineness of 1.2 denier (D), this fiber is relatively fine. The denier is a unit measuring the linear density of the fiber. A 1.2D fineness endows the fiber with the ability to create yarns and fabrics that possess a smooth and soft handfeel. This makes it highly desirable for applications where comfort and a luxurious texture are key, such as in high - end fashion items and intimate apparel.
- Length: Measuring 38 millimeters (mm) in length, this fiber is well - proportioned for staple - fiber - based textile manufacturing processes. The 38 - mm length allows for efficient fiber handling during spinning operations. It enables the fibers to be easily interlocked and twisted together, resulting in the formation of strong and uniform yarns. The longer length compared to some other staple fibers also contributes to better fiber alignment within the yarn, enhancing the overall strength and integrity of the final textile product.
Color
- The fiber is dyed black, presenting a deep and intense color. The dyeing process is executed with top - grade colorants, ensuring outstanding colorfastness. This black color remains vibrant and stable over time, even when subjected to harsh conditions such as repeated laundering, prolonged exposure to sunlight, and heavy abrasion. The versatility of the black color makes it a popular choice across various industries. In the fashion world, it is a staple for creating classic, sophisticated, and edgy looks. In industrial and technical textiles, the black color can help in concealing dirt and providing a more professional and sleek appearance.
Material Properties
- Strength: As a polyester fiber, it exhibits excellent strength. Polyester is renowned for its high tensile strength, which means that the 1.2D x 38mm black polyester staple fiber can endure substantial mechanical stress without breaking. This strength property is vital for applications where the textile product needs to withstand heavy usage, such as in workwear, upholstery fabrics for furniture that experiences frequent use, and industrial sewing threads.
- Wrinkle Resistance: It has remarkable wrinkle - resistant properties. Polyester fibers have a natural ability to maintain their shape, and this characteristic is highly valued in the textile industry. Fabrics made from this fiber tend to resist wrinkling, which reduces the need for frequent ironing or steaming. This makes it an ideal choice for garments and home textiles that require low - maintenance and a neat appearance.
- Moisture Management: The fiber has low moisture absorption. Polyester does not readily absorb water, which is beneficial in several ways. It allows fabrics made from this fiber to dry quickly, making them suitable for sportswear and outdoor apparel where rapid drying is essential. Additionally, the low moisture absorption helps prevent the growth of mold and mildew, extending the lifespan of the textile product and ensuring its hygienic quality, especially in humid environments.
