Embodiment 1

[0016] Such as figure 1 As shown, a new type of breathable chemical fiber 1, the cross-section of the chemical fiber 1 is circular, with two diameters perpendicular to each other inside, the diameter divides the circular ring into four fan-shaped hollow pipes 11, and each fan-shaped hollow The duct 11 is provided with air circulation holes 13 .

[0017] In addition, the hollow pipes 11 are not communicated with each other.

[0018] Furthermore, the air circulation hole 13 is arranged at the center of the outer wall 12 of each fan-shaped hollow pipe 11 .

[0019] Moreover, the sizes of the air circulation holes 13 are the same.

[0020] Meanwhile, the chemical fiber 1 is polyester.

Embodiment 2

[0022] A new type of breathable chemical fiber 1, the cross section of the chemical fiber 1 is ring-shaped, and there are three diameters perpendicular to each other inside, and the diameter divides the inside of the ring into six fan-shaped hollow pipes 11, and each fan-shaped hollow pipe 11 is provided with Air circulation holes 13.

[0023] In addition, the hollow pipes 11 are not communicated with each other.

[0024] Furthermore, the air circulation hole 13 is arranged at the center of the outer wall 12 of each fan-shaped hollow pipe 11 .

[0025] Moreover, the sizes of the air circulation holes 13 are the same.

[0026] Meanwhile, the chemical fiber 1 is spandex.

Embodiment 3

[0028] A new type of air-permeable chemical fiber 1, the cross-section of the chemical fiber 1 is circular, and there are four diameters perpendicular to each other inside, and the diameter divides the circular ring into eight fan-shaped hollow pipes 11, and each fan-shaped hollow pipe 11 is provided with Air circulation holes 13.

[0029] In addition, the hollow pipes 11 are not communicated with each other.

[0030] Furthermore, the air circulation hole 13 is arranged at the center of the outer wall 12 of each fan-shaped hollow pipe 11 .

[0031] Moreover, the sizes of the air circulation holes 13 are the same.

[0032] Meanwhile, the chemical fiber 1 is acrylic fiber.

[0033] Implementation of the present invention: a punching device is arranged around the nozzle hole of the spinneret, the number of punching needles of the punching device is the same as the number of the hollow pipe 11, and the outer wall 12 and the center of the hollow pipe 11 are aligned, and the nozzl...

Abstract

The invention provides a novel breathable chemical fiber. The cross section of the fiber is in an annular shape. The internal is provided with at least two diameters which are vertical to each other. The diameters divide the internal of the ring into a group of fan-shaped hollow pipes. Each fan-shaped hollow pipe is provided with an air ventilation hole. The novel breathable chemical fiber can greatly improve functions of moisture absorption and sweat releasing of chemical fibers and reducing temperature of chemical fiber fabrics.

Description

technical field [0001] The invention relates to the field of chemical fibers, in particular to a novel breathable chemical fiber. Background technique [0002] The cross-section of traditional chemical fiber is solid structure, and solid chemical fiber is not hygroscopic. Therefore, in order to improve the hygroscopic performance of chemical fiber, a chemical fiber with hollow cross-section has been developed in the industry, that is, a plurality of hollow pipes are arranged axially on the body of the chemical fiber, usually 3 , 7 or 16 hollow pipes, allowing air to circulate through the hollow pipes of chemical fibers, so that the functions of moisture absorption and perspiration of chemical fibers and reducing the temperature of chemical fiber fabrics can be improved to a certain extent. However, the degree of improvement of the above-mentioned functions is not very satisfactory for the chemical fiber of the hollow ring structure. Contents of the invention [0003] In o...
