These and other features, aspects, and advantages of the present invention will become better understood from the following description and appended claims.

It is to be understood that the foregoing general description

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

Although a series of operations or steps are hereinafter described to illustrate the methods disclosed herein, the order of the operations or steps is not to be construed as limiting. 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 are required to implement embodiments of the invention. Moreover, each of the operations or steps described herein can include a number of sub-steps or actions.

In order to solve the problems described in the prior art, the present disclosure A deodorizing fiber and a method of making the same are provided. The deodorizing fiber contains a deodorant, and the deodorant includes zeolite powder and lauric acid present in the micropores of the zeolite powder. The zeolite powder is a microporous inorganic material which can be deodorized by physically adsorbing odor. Lauric acid reacts with odor and deodorizes by chemical neutralization. Therefore, the deodorizing fiber of the present disclosure can be deodorized by a deodorizing agent having a double deodorizing mechanism, and the deodorizing rate of the deodorizing fiber can be improved.

The method for producing the deodorizing fiber comprises the following steps: (a) heating and stirring the zeolite powder and lauric acid to form a deodorizing agent, and the weight ratio of the zeolite powder to the lauric acid is 0.3 to 1.5. (b) A fiber raw material composed of nylon 6 or nylon 610 is provided. (c) A kneading granulation procedure is carried out for 0.5 part by weight to 2.5 parts by weight of the deodorant and 97.5 parts by weight to 99.5 parts by weight of the 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 deodorizing fiber.

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

In carrying out operation (a), in some embodiments, the temperature of the heated agitation procedure is from 80 °C to 100 °C. In some embodiments, the heating and agitation procedure is performed for a period of from 1 hour to 2 hours. In other embodiments, the weight ratio of zeolite powder to lauric acid is from 0.5 to 1. Since the zeolite powder has micropores, in the deodorant, a part of the lauric acid is coated with the zeolite powder. On the outer surface, another portion of lauric acid is present in the micropores of the zeolite powder and is coated on the inner surface of the zeolite powder.

After the operation (a), the manufacturing method further includes a drying process for the deodorant. The drying procedure has a temperature of 80 ° C to 100 ° C and a time of 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 the deodorant and the fiber raw material and performing a drying process. The drying procedure has a temperature of 80 ° C to 100 ° C and a time of 12 hours to 24 hours.

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

At the time of operation (d), the melt spinning process is carried out at a temperature of 245 ° C to 280 ° C. In general, since the boiling point of lauric acid (298.9 ° C) is only slightly higher than the temperature of the melt spinning process, lauric acid is liable to be lost during melt spinning during the kneading granulation process. However, it is worth noting that in the deodorant of the present disclosure, since the zeolite powder has micropores, the lauric acid present in the micropores of the zeolite powder is less likely to be melt-spun. It is lost during the silk process and can remain in the final deodorizing fiber. In other words, the present disclosure utilizes micropores of zeolite powder to encapsulate lauric acid, making lauric acid less susceptible to high temperature loss due to the melt spinning process. Therefore, the deodorizing fiber of the present disclosure can be deodorized by the double deodorizing mechanism provided by zeolite powder and lauric acid, and has a rather excellent deodorizing rate.

In particular, the deodorizing fibers of the present disclosure include a fibrous body and a deodorant. The fiber body is composed of nylon 6 or nylon 610. The deodorant is attached to the fiber body. The deodorant includes zeolite powder and lauric acid present in the microvoids of the zeolite powder. According to the above production method, the deodorant is formed by heating and stirring a zeolite powder having a weight ratio of 0.3 to 1.5 and lauric acid. In some embodiments, the temperature of the heated agitation procedure is from 80 °C to 100 °C.

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

In some embodiments, the zeolite powder has a particle size ranging from 0.5 microns to 2 microns. In some embodiments, the zeolite powder has a specific surface area in the range of from 120 m ² /g to 140 m ² /g.
