This staple fiber has a fineness of 1.2 denier (D). Such a fine diameter contributes to its soft and smooth texture. The 1.2D fineness is particularly suitable for applications where a gentle touch is essential, like in the production of high - end apparel such as delicate blouses, fine - gauge knitwear, and luxury undergarments. It allows for the creation of fabrics that drape well and feel comfortable against the skin.

② Length

With a length of 38 millimeters (MM), the fiber is well - proportioned for the spinning process. The 38 - MM length enables efficient drafting, where the fibers are pulled and aligned in a parallel manner. This length also promotes good fiber cohesion during twisting, resulting in the formation of strong and uniform yarns. During spinning, the consistent length helps to minimize fiber breakage, ensuring a smooth and continuous production of yarns with fewer defects.

Fluorescent Brightening Characteristics

① Optical White Enhancement

The fiber exhibits an optical white property, which is achieved through the use of fluorescent brightening agents. These agents are integrated into the fiber structure during manufacturing. When exposed to light, especially ultraviolet (UV) light, the fluorescent brightening agents absorb the UV rays. Subsequently, they re - emit visible light, enhancing the fiber's overall whiteness. This makes the fiber appear much brighter and more vivid compared to regular white fibers, creating a more intense and eye - catching white color.

② Reddish Tinge

In addition to its enhanced optical whiteness, the fiber has a distinct reddish tinge. This reddish undertone adds a unique and warm aspect to the white color. The combination of the bright optical white and the reddish hue creates a more complex and interesting color effect. The reddish tinge can be used to create a sense of warmth and elegance in textile products. It is different from the more common blue - or green - tinged optical white fibers, offering a new aesthetic option in the textile market.

Performance and Applications

① Spinnability

This 1.2D*38MM OPTICAL WHITE REDDISH fiber shows good spinnability. Despite its fine structure and the presence of fluorescent agents, it can be easily processed into high - quality yarns. The fiber's physical properties allow it to be effectively drafted, aligned, and twisted without significant breakage. This makes it suitable for various spinning methods, such as ring spinning, open - end spinning, and air - jet spinning.

② Strength and Durability

The fiber has sufficient strength to withstand the mechanical forces during spinning, weaving, and knitting processes. It can endure stretching, bending, and abrasion, contributing to the durability of the final textile products. Fabrics made from this fiber are likely to maintain their shape and integrity even after repeated use and washing.

③ Applications

Apparel Industry: In the fashion world, this fiber can be used to create unique white - colored garments. For example, it can be used in the production of bridal gowns, where the warm reddish - tinged optical white can add a touch of romance and luxury. It can also be used in high - end ready - to - wear collections, such as white blazers or dresses, to make a fashion statement with its distinct color.
Home Textiles: In the home textile sector, it can be utilized in the manufacturing of bed linens, curtains, and tablecloths. The warm optical white with a reddish tinge can create a cozy and inviting atmosphere in living spaces. It can also be used in decorative pillows and throws to add a pop of color and style to interior decor.
