It should be understood that the foregoing general description and the following detailed description are merely exemplary and explanatory and are intended to provide further explanation of the invention as claimed.

The following disclosure provides many different embodiments or examples to implement different features of the invention. The composition and layout of specific examples are described below to simplify the present invention. These are, of course, examples only and are not intended to be limiting.

Although a series of operations or steps are used to explain the method disclosed herein, the order of these operations or steps should not be interpreted as a limitation of the present invention. For example, certain operations or steps may be performed in a different order and / or concurrently with other steps. In addition, not all illustrated operations, steps, and / or features need to be performed to implement embodiments of the present invention. In addition, each operation or step described herein may include several sub-steps or actions.

To solve the problems described in the prior art, this disclosure Provided is a deodorizing fiber and a manufacturing method thereof. The deodorizing fiber contains a deodorant, and the deodorant includes zeolite powder and lauric acid existing in the micropores of the zeolite powder. Zeolite powder is a microporous inorganic material that can be deodorized by physically adsorbing odor. Lauric acid can react with odor and deodorize by chemical neutralization. Therefore, the deodorizing fiber of the present disclosure can be deodorized by using a deodorant having a dual deodorizing mechanism, thereby improving the deodorizing rate of the deodorizing fiber.

The manufacturing method of deodorizing fiber includes the following operations: (a) heating and stirring the zeolite powder and lauric acid to form a deodorant, and the weight ratio of the zeolite powder and lauric acid is 0.3 to 1.5. (b) Provide a fiber material composed of nylon 6 or nylon 610. (c) performing a kneading granulation process on 0.5 to 2.5 parts by weight of a deodorant and 97.5 to 99.5 parts by weight of a fiber raw material to form a fiber mother particle. (d) The fiber masterbatch is subjected to a melt spinning process at a temperature of 245 ° C to 280 ° C to form a deodorized fiber.

Before performing operation (a), in some embodiments, the manufacturing method further includes a drying process of the zeolite powder, the temperature of the drying process is 110 ° C to 130 ° C, and the time is 8 hours to 16 hours. In some embodiments, the manufacturing method further includes using a solvent to dissolve lauric acid, wherein a weight ratio of lauric acid to the solvent is 0.2 to 0.7. The solvent is, for example, an alcohol, and the alcohol is, for example, methanol.

During operation (a), in some embodiments, the temperature of the heating and stirring program is 80 ° C to 100 ° C. In some embodiments, the heating and stirring process is performed for 1 to 2 hours. In other embodiments, the weight ratio of zeolite powder to lauric acid is 0.5 to 1. Because the zeolite powder has micropores, part of the lauric acid in the deodorant will cover the zeolite powder. On the outer surface, another part of lauric acid is present in the micropores of the zeolite powder, covering the inner surface of the zeolite powder.

After performing the operation (a), the manufacturing method further includes a drying process for the deodorant. The temperature of the drying program is 80 ° C to 100 ° C, and the time is 8 hours to 16 hours. In some embodiments, the drying process is performed under vacuum.

Prior to operation (c), the manufacturing method further includes mixing a deodorant and a fiber material and performing a drying process. The temperature of the drying program is 80 ° C to 100 ° C, and the time is 12 hours to 24 hours.

When performing operation (c), in some embodiments, the temperature of the kneading granulation program is 220 ° C to 260 ° C. In some embodiments, the manufacturing method further includes adding a dispersant, so that the dispersant, the deodorant and the fiber raw material are subjected to a kneading granulation process together. The dispersant is, for example, ammonium stearate wax. In some embodiments, the dispersant is from 0.05 to 0.15 parts by weight. In some embodiments, the manufacturing method further includes adding an antibacterial agent, so that the antibacterial agent, deodorant, and fiber raw material are subjected to a kneading granulation process together. The antibacterial agent is, for example, silver zirconium phosphate. In some embodiments, the antibacterial agent is 0.5 to 1.5 parts by weight.

In operation (d), the melt spinning process is performed at a temperature of 245 ° C to 280 ° C. In general, since the boiling point (298.9 ° C) of lauric acid is only slightly higher than the temperature of the melt spinning process, lauric acid is easily lost in the process of melt spinning during the granulation process. However, it is worth noting that in the deodorant of the present disclosure, since the zeolite powder has micropores, the lauric acid existing in the micropores of the zeolite powder is less likely to be melt-spun. It is lost during the silk process and can be retained in the final deodorizing fiber. In other words, the present disclosure utilizes pores of zeolite powder to encapsulate lauric acid, making it difficult to lose lauric acid due to the high temperature of the melt spinning process. Therefore, the deodorizing fiber of the present disclosure can utilize the dual deodorizing mechanism provided by zeolite powder and lauric acid to perform deodorization, and has a fairly excellent deodorizing rate.

In detail, the deodorizing fiber of the present disclosure includes a fiber body and a deodorant. The fiber body consists of nylon 6 or nylon 610. The deodorant is attached to the fiber body. Deodorants include zeolite powder and lauric acid present in the micropores of the zeolite powder. According to the aforementioned manufacturing method, it is known that the deodorant is formed by heating and stirring the zeolite powder and lauric acid in a weight ratio of 0.3 to 1.5. In some embodiments, the temperature of the heating and stirring procedure is 80 ° C to 100 ° C.

In some embodiments, the deodorizing fibers are formed through a melt spinning process at a temperature of 245 ° C to 280 ° C. In some embodiments, the specifications of the deodorizing fiber are in the range of 60d / 24f to 80d / 24f. For example, the specification of deodorizing fiber is 70d / 24f.

In some embodiments, the particle size of the zeolite powder is in a range between 0.5 microns and 2 microns. In some embodiments, the specific surface area of the zeolite powder is in a range between 120 m ² / g and 140 m ² / g.
