Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments.
Example one
This embodiment will be described in detail with reference to fig. 1. The wear-resistant flame-retardant aramid spandex core-spun yarn comprises a first core wire 11 and a second core wire 12 which are arranged in parallel, and a coating layer 2 coated on the outer sides of the first core wire 11 and the second core wire 12.
The first core yarn 11 is a spandex filament, and the second core yarn 12 is an aramid staple yarn or a nylon filament; the coating layer 2 is made of nylon filament yarns or aramid staple yarns. Specifically, in this embodiment, the second core wire 12 is a nylon filament, and the coating layer 2 is an aramid spun yarn. The production of the spandex filament core-spun yarn is to process the stretching state and feed the spandex filament in parallel, so that the core-spun yarn has elasticity.
Further, the fineness of the spandex filament in this embodiment is 40-70D. The fineness of the aramid staple yarn was 32S. The fineness of the nylon filament is 70-140D, and the section of the cotton filament is circular.
The nylon filament and the spandex filament which are arranged in parallel not only provide elasticity for the core-spun yarn, but also enable the core-spun yarn to have higher strength. The short fiber yarn has good wear resistance, and aramid fiber in the used aramid short fiber yarn is aramid fiber 1313.
The percentage of the volume of oxygen required for the material to burn in air is called the limiting oxygen index, and the larger the limiting oxygen index is, the better the flame retardant performance is. The oxygen content in the air is 21 percent, while the limit oxygen index of the aramid fiber 1313 is more than 28 percent, and the aramid fiber is a flame-retardant fiber, so that the aramid fiber can not be combusted in the air, can not support combustion and has self-extinguishing property. This inherent property, derived from the molecular structure itself, makes the aramid 1313 permanently flame retardant and hence is known as "fire-resistant fiber".
Example two
This embodiment will be described in detail with reference to fig. 1. The wear-resistant flame-retardant aramid spandex core-spun yarn comprises a first core wire 11 and a second core wire 12 which are arranged in parallel, and a coating layer 2 coated on the outer sides of the first core wire 11 and the second core wire 12.
The first core yarn 11 is a spandex filament, and the second core yarn 12 is an aramid staple yarn or a nylon filament; the coating layer 2 is made of nylon filament yarns or aramid staple yarns. Specifically, the second core yarn 12 is aramid staple fiber yarn, the coating layer 2 is a cotton filament yarn, and the nylon fiber has good wear resistance and is superior to other chemical fibers and natural fibers.
EXAMPLE III
This embodiment will be described in detail with reference to fig. 2. The wear-resistant flame-retardant aramid spandex core-spun yarn comprises a first core wire 11 and a second core wire 12 which are arranged in parallel, and a coating layer 2 coated on the outer sides of the first core wire 11 and the second core wire 12. The first core yarn 11 is a spandex filament, and the second core yarn 12 is an aramid staple yarn or a nylon filament; the coating layer 2 is made of nylon filament yarns or aramid staple yarns.

In this embodiment, the cross section of the nylon filament includes a single fiber 21 having a circular cross section, and a protrusion 22 provided on the outer peripheral surface of the single fiber 21. Because of the single fiber 21 with the circular cross section, the nylon filament has a hollow structure and can have a certain warm-keeping effect. And the provided bulge 22 can improve the good wear resistance.
Example four
This embodiment will be described in detail with reference to fig. 3. The wear-resistant flame-retardant aramid spandex core-spun yarn comprises a first core wire 11 and a second core wire 12 which are arranged in parallel, and a coating layer 2 coated on the outer sides of the first core wire 11 and the second core wire 12.
