[0046] In this embodiment, the cool-feeling dyeable composite fiber is a fiber made by composite spinning of polyethylene and an easily dyeable material; the easily dyeable material is polyamide; polyethylene itself has a high thermal conductivity, which can quickly conduct heat, making the fabric cool-feeling. However, traditional ultra-high molecular weight polyethylene fiber is difficult to dye due to its dense structure. After composite spinning with polyamide, the dyeability of the composite fiber is improved due to the dyeability of polyamide. The fabric made of this fiber can achieve both dyeing and printing while also having the cool-feeling properties of polyethylene fiber.
[0047] In practical applications, cool-feeling dyeable composite fibers adopt a cross-shaped cross section; because the cross-shaped fiber has four grooves, it has a large porosity, good moisture absorption, moisture wicking and quick drying effect, and its cross structure reduces the contact points between the fiber and the skin, making it comfortable to wear.
[0048] Furthermore, cool-feeling dyeable composite fibers can also be combined with mica modification technology, using polyamide as a carrier to add mica microparticles (nanoscale). Due to the excellent thermal conductivity and hydration effect of mica itself, the thermal conductivity and moisture absorption of the fabric can be further enhanced, making it more comfortable to wear.
[0049] According to one aspect of this utility model, in the first to twelfth cycles, the specification of the cool-feeling dyeable composite fiber is 83Dtex / 72F.
[0050] Among them, loop formation, tuck loop, and float loop are knitting terms, referring to knitting weaving techniques. There are three types of loop formation: loop formation, tuck loop, and float loop. Loop formation is a process in which a loop is fully utilized by the knitting needle, and the yarn is formed into a loop using the knitting needle and other loop-forming mechanisms on a knitting machine. Tuck loop is when, during knitting, some old loops on certain needles enter the needle hook together with the new yarn, causing the new yarn to form an unclosed suspension arc, while the old loops form elongated loops. Float loop refers to a situation where, at the beginning of loop formation, when the knitting needle rises to unwind, due to some reason, the old loop does not retreat to the needle bar below the needle latch but remains hanging on the needle latch. When the knitting needle descends, the old loop returns to the needle hook and cannot form a new loop. This phenomenon is called a float loop. The upper needle is also known as the needle plate, and the lower needle is also known as the needle cylinder.

The composite fiber has a cross-shaped cross section with four grooves, resulting in high porosity and excellent moisture absorption, wicking, and quick-drying properties.

Furthermore, the composite fiber, combined with mica modification technology and using polyamide as a carrier, further enhances the fabric's thermal conductivity and moisture absorption, making it even more comfortable to wear.
