Embodiment 1

[0037] Such as figure 1 with figure 2 As shown, a functional nylon FDY fiber disclosed in the first embodiment of the present invention includes a fiber body 1 . As an inventive point of the present invention, the fiber body 1 is a hollow fiber, and the cross section of the hollow fiber body 1 is honeycomb-shaped, thereby improving the air permeability of the fiber body 1 and increasing the elasticity. As a preference, the fiber body 1 of a functional nylon FDY fiber disclosed in this embodiment of the present invention is also provided with a heat-retaining fiber 2. As a further preference, in this embodiment of the present invention, the heat-retention fiber 2 is a short filament, Such as figure 1 with figure 2 As shown, the thermal fiber 2 is embedded in the fiber body 1 and integrated with the fiber body 1 . The heat-retaining fiber 2 has many options, such as cotton fiber, or soybean protein fiber, or cotton fiber and soybean protein fiber, and in this embodiment of...

Embodiment 2

[0040] Such as image 3 As shown, a functional nylon FDY fiber disclosed in the second embodiment of the present invention has basically the same structure as in Example 1, except that the thermal fiber 2 is a filament, such as image 3 As shown, the heat-retaining fiber 2 is threaded in the honeycomb cavity of the fiber body 1, and the heat-retaining fiber 2 can be distributed evenly or regularly, and there is no limitation here.

[0041] A functional nylon FDY fiber disclosed in the above two embodiments improves the thermal performance and air permeability of the fiber, thus improving the wearing comfort.

[0042] The present invention also discloses a production process of a functional nylon FDY fiber provided in the above-mentioned embodiment 1 and embodiment 2, which specifically includes the following steps:

Embodiment 3

[0044] The production process of a kind of functional nylon FDY fiber that above-mentioned embodiment 1 provides specifically comprises the following steps:

[0045] A) preparing materials, storing the raw materials in the silo in advance, preferably, the silo is filled with nitrogen protection gas, and the residence time of the raw materials in the silo is less than 24h;

[0046] B) Melting, introducing raw materials and thermal insulation fibers into a screw extruder with heating function to melt at the same time to obtain a raw material melt, during which the raw materials and thermal insulation fibers are mixed;

[0047] Preferably, the heating temperature of the screw extrusion is between 250°C and 260°C. Specifically, the screw extruder is equipped with six heating zones, the temperature of the first heating zone is 250°C, the temperature of the second heating zone is 254°C, the temperature of the third heating zone is 256°C, and the temperature of the fourth heating zon...

Abstract

The invention provides a functional chinlon FDY fiber and a production process thereof. The functional chinlon FDY fiber comprises a fiber body, wherein the fiber body is a hollow type fiber; the section of the hollow fiber body is in the shape of honeycomb; a heating fiber is arranged in the fiber body, and the fiber body is externally coated with a finishing agent layer; the production process includes steps of preparing-fusion-measurement-spinning and molding-coating of finishing agent layer-cooling-applying oil and pre-networking-drafting-re-networking-applying oil again, bending and shaping. The functional chinlon FDY fiber disclosed in the invention has good ultraviolet-proof function, and the ultraviolet-proof function is improved to 40-65 UPF, and the ultraviolet-proof effect is durable; besides, the fiber has the function of preventing dust from attaching, and can effectively prevent pollen and dust from allergy, improve heat preservation and air breathing performances and promote the comfort level; besides, the functional chinlon FDY fiber is high in production efficiency, big in intensity, less in broken lines, and high in finished product yield.

Description

technical field [0001] The invention relates to the technical field of spinning materials, in particular to a functional nylon FDY fiber and a production process thereof. Background technique [0002] Nylon fiber is the earliest synthetic fiber variety put into industrial production in the world. It is a kind of nylon synthesized by polycondensation reaction of aliphatic dibasic acid and diamine or aliphatic amino acid, and then melt-spun. The general term for synthetic fibers. Because they all contain amide bonds, they are collectively called nylon fibers. It is a kind of heterochain synthetic fiber. Among them, polycaprolactone amide fiber and polyhexamethylene adipamide fiber have the largest output and are the most widely used. Nylon is not only the earliest industrialized synthetic fiber variety, but also has many excellent properties, such as high strength, elasticity, wear resistance and weather resistance, so it is very popular among consumers. With the continuou...
