This application claims the benefit of Taiwan Patent Application No. 110129501, filed on Aug. 10, 2021, which is hereby incorporated by reference for all purposes as if fully set forth herein.
This application relates to the technical field of protective cloths, and specifically, to a deodorant and antibacterial high strength protective cloth and a manufacturing method thereof.
Textiles in daily life are usually in contact with bodies of users. With the improvement of the standard of living and the rise of awareness of health of people, functional textiles with antibacterial, antifungus, or deodorant effects are increasingly popular in the market. Generally, fiber products using a deodorant or antibacterial fiber need to have laundering durability. In addition, for wide application, the deodorant fiber is further required to be dyed like a common fiber product. In a conventional process, an organic antibacterial agent is usually applied to a surface of a fiber. However, some organic antibacterial agents may have problems such as production of toxic substances, poor heat resistance, easy decomposition, easy volatilization, or possible microbial resistance.
In addition, an existing copper-ion fiber in the market usually exists using terylene or nylon as a carrier, which is obtained by blending near-nano-scaled copper powder or copper compounds into a fiber, that is, merely by adding copper powder into the fiber. By blending, not only a copper content of the fiber does not exceed 1%, but also the copper content may decrease with time. Since the copper-ion fiber exists using terylene or nylon as a carrier, hydrophilicity thereof is generally poor, and a fiber moisture regain rate is the same as that of the original fiber. Fabrics made of the copper ion fiber in the market require addition of more than 0-50% of the copper ion fiber to achieve antibacterial and deodorant effects. Not only antibacterial and deodorant effects and costs are undesirable, but also a protection formed thereby cannot realize more desirable antibacterial and deodorant effects.
Therefore, this specification provides a deodorant and antibacterial high strength protective cloth and a manufacturing method thereof.
In view of the disadvantages of the related art, this application discloses a deodorant and antibacterial protective cloth and a manufacturing method thereof, to obtain a deodorant and antibacterial high strength protective cloth.
This application is achieved through the following technical solution:
In order to achieve the above objective, this application provides a method for manufacturing a deodorant and antibacterial protective cloth. The method comprises the following steps:

A temperature for drying in step C is controlled between 100° C. and 150° C.
The first cooling in step D means that the first-stage thread continuously passes through a cooling tank over a period of time, and the second cooling in step G is natural air cooling.
The cooling in step D means that the single-thread yarn continuously passes through a cooling tank over a period of time.
In step E, the tensile device comprises a plurality of roller sets arranged in sequence to stretch the first-stage thread.
This application further aims to provide a deodorant and antibacterial protective cloth, manufactured by using the method for manufacturing a deodorant and antibacterial protective cloth.
This application has the following beneficial effects:
A nanoscale fiber thread may be obtained by simply performing the process of this application at a room temperature without requiring expensive environment control devices. Therefore, this application has low costs, and can reduce energy consumption and high thermal pollution. The obtained first fiber thread and second fiber thread are intersected and laminated to form a plurality of bonding layers, so as to form the deodorant and antibacterial protective cloth. By means of the laminated arrangement, flexibility of an original fiber thread is maintained, the protective cloth has a very high strength, which is unlikely to be pierced, so that a protection factor is increased, and the laminated arrangement enables desirable breathability for the protective cloth, so that the protective cloth has a deodorant effect. Since the protective cloth is made of the fiber threads, and the fiber threads have strong antibacterial properties, the protective cloth also has a desirable antibacterial effect.
