Description

Sterilizing knitted fabric and manufacturing method thereof

Technical Field

The invention relates to a sterilization knitted fabric and a manufacturing method thereof, in particular to a sterilization knitted fabric with two different spinning materials and a manufacturing method thereof.

Background

The nano silver ion in the nano silver antibacterial yarn can block virus and inhibit the growth of foreign organisms harmful to human body. Moreover, the nano-silver ions can also continuously release negative ions and far-infrared ray energy, and can effectively increase blood circulation and promote metabolism. In addition, the nano silver ion fiber is a single body formed by polymerizing silver and fiber, so that the silver and the fiber cannot be stripped. Therefore, the bacteriostatic effect of the nano-silver antibacterial yarn is very durable and is not easy to decrease with time. Because of this, the knitted fabric with nano silver antibacterial yarn is often used as the inner layer of the mask. However, after the knitted fabric with the nano silver antibacterial yarn contacts the skin of the wearer, the wearer is likely to feel uncomfortable, and the mask cannot be worn for a long time.

Therefore, it is worth the thinking of those skilled in the art to make a sterilized knitted fabric with antibacterial effect and comfortable wearing.

Detailed Description

To explain technical contents, structural features, and objects and effects of the technical solutions in detail, the following detailed description is given with reference to the accompanying drawings in conjunction with the embodiments.

Referring to fig. 1, fig. 1 is a flow chart illustrating a method 10 for manufacturing a sterilized knitted fabric according to the present embodiment. Wherein, the sterilization knitted fabric is mainly used as the inner layer cloth of the mask, namely the material which is directly contacted with the face of a wearer, the manufacturing method 10 of the sterilization knitted fabric comprises the following steps:

first, please refer to step S1, a plurality of nano far infrared antibacterial yarns and a plurality of bamboo charcoal hollow yarns 123 are provided. Wherein, the nano far infrared ray antibacterial yarn has a plurality of silver ions, the content of the silver ions is 0.8% -1% of the whole antibacterial yarn, so the nano far infrared ray antibacterial yarn 121 can continuously release negative ions and far infrared ray energy, and has excellent bacteriostatic effect. In addition, the bamboo charcoal hollow yarn 123 has the effects of deodorizing, adjusting moisture, and adsorbing chemicals, and the bamboo charcoal hollow yarn 123 itself has excellent air permeability.

Then, referring to step S2 and fig. 2 (fig. 2 is a partial enlarged view of the greige cloth 12), the nano far infrared antibacterial yarn 121 and the bamboo charcoal hollow yarn 123 are interwoven to form the greige cloth 12. In detail, the method uses a circular knitting double-faced knitting machine (not shown) to interweave the nano far infrared ray antibacterial yarn 121 and the bamboo charcoal hollow yarn 123 to form the gray cloth 12. It is noted that the knitted bamboo charcoal hollow yarns 123 are arranged in a checkerboard pattern, and the knitted nano far infrared antibacterial yarns 121 are surrounded by the bamboo charcoal hollow yarns 123. In the above, the diameter of the circular knitting double jersey knitting machine is 34 inches, and 24 needles are arranged in one inch of the needle cylinder.

Then, referring to step S3, the raw fabric 12 is subjected to a refining process at a refining temperature of 120-140 ℃, preferably 130 ℃, to form a refined fabric (not shown). In detail, before the dyeing process, impurities such as colloid, wax, grease, etc. in the raw fabric 12 need to be removed, which is called "scouring", and the scoured raw fabric 12 can improve the purity of cellulose and increase the whiteness of the fabric, so as to achieve a good dyeing effect.

Thereafter, referring to step S4, the scouring cloth is dyed by a dyeing process, and the scouring process and the dyeing process take about 1.5 hours.

Then, referring to step S5, the dyed refined cloth is subjected to a shaping process, in which a shaping machine, such as a blessing 9-chamber shaping machine, is used to finish and iron the refined cloth at a high temperature to form the sterilized knitted cloth. Wherein, the ironing temperature of the shaping process is 160-180 ℃, and the better ironing temperature is 170 ℃. It is noted that the melting point of the hollow bamboo charcoal yarn 123 is 130 ℃ lower than the ironing temperature, so the sizing process is performed on the refined cloth by moving 25 meters per minute to prevent the hollow bamboo charcoal yarn 123 from breaking after being heated. Specifically, the scouring cloth passed through the 8-section oven of the setter in 1 minute (9-section oven for a 9-chamber setter), so the scouring cloth was moving throughout the setting process, rather than being stationary. Therefore, each part of the refined cloth is finished and ironed at high temperature only in a short time, so that the bamboo charcoal hollow yarn 123 in the finished and ironed sterilized knitted cloth has no problem of yarn breakage.

Since only half of the structure of the sterilized knitted fabric is the nano far infrared ray antibacterial yarn 123, the antibacterial effect is slightly inferior to that of the knitted fabric made of only nano silver antibacterial yarn. In order to enhance the antibacterial effect of the sterilized knitted fabric, an antibacterial agent, such as the type of the antibacterial agent

ZO6R30700-480, the main component of which is zinc ion. Therefore, the effects of antibiosis, mould prevention and deodorization can be enhanced, and the original function of the refining cloth can not be changed. In addition, the refining cloth is added with a bridging agent besides the antibacterial agent, and the bridging agent can improve the weather resistance, the solvent resistance and the corrosion resistance of the refining cloth.

Compared with the knitted fabric made of nano silver antibacterial yarn, the sterilized knitted fabric made by the method 10 has the effects of bacteriostasis, deodorization, ventilation and moisture absorption. Moreover, when the sterilized knitted fabric is made into a mask, the bamboo charcoal hollow yarns 123 in the checkered shape further enhance the wearing comfort.

Although the present invention has been described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
