Description

Technical Field

[0001] The invention relates to the technical field of deodorizing socks, in particular to a production process of deodorizing socks. Background Art

[0002] Existing socks are one of the essential daily necessities for people. They are worn on the feet for decoration, protection and beautification. With the development of science and technology and the progress of the textile industry, people have higher and higher requirements for socks. In addition to appearance quality, color and style, multifunctional socks made of various fibers with different properties are becoming more and more popular.

[0003] At present, for people who wear sports shoes for a long time, intense exercise causes a lot of sweating in the feet. If the air in the feet is not circulated, bacteria will easily form on the soles of the feet, leading to symptoms such as athlete's foot and itchy feet. Many sports socks use a simple plain structure with a flat surface. After wearing them for a period of time, sweat from the feet is easy to accumulate, reducing the friction coefficient between the socks and the feet, making them easy to slip and not conducive to further exercise. Moreover, the heel of the socks is very easy to fall off during exercise, sliding from the heel to the sole of the foot. During exercise, many movements require the sole of the foot to be stressed, especially the area between the front end of the sole and the sole of the foot. This area of ​​the socks is most susceptible to wear.

[0004] As a knitted product that is closely related to people in daily life, socks must have good physical and mechanical properties, and at the same time meet people's requirements for multi-functions such as moisture absorption, perspiration, antibacterial, and deodorization for product comfort;

[0005] The traditional added bamboo fiber is bamboo dissolved in carbon disulfide and washed with strong acid and alkali before spinning, and the bamboo quinone has been lost. The traditional chemical antibacterial agents have poor washing resistance. The traditional silver ion antibacterial agents have the risk of heavy metal deposition and are not conducive to exports to the EU region which has requirements for the content of silver ion antibacterial agents. Summary of the invention

[0006] The technical problem to be solved by the present invention is: in order to overcome the above problems, a production process of deodorizing socks is provided, which solves the above problems.

[0007] The present invention solves the technical problem by adopting the following technical scheme: including adopting the following materials to be post-processed through process equipment;

[0008] The raw yarn is finished, and the cotton yarn fiber, spandex fiber, and viscose fiber are finished and blended into yarn in a mass fraction ratio of 8-10:1-2:1-2. The obtained yarn is a mixed raw yarn, and then the mixed raw yarn is placed in an impregnation tank for impregnation finishing. The impregnation liquid is a copolymer solution of a new biopolymer 3-hydroxybutyrate and 3-hydroxyvalerate, and the solution concentration is 6.8%-10.2%. The impregnation temperature is controlled between 75 degrees Celsius and 82 degrees Celsius. The impregnation time (minutes) is the number of the mixed raw yarn multiplied by the weight of the mixed raw yarn (the weight unit is tons). For example, one ton of mixed raw yarn with a count of 20 needs to be impregnated for 20 minutes. After the impregnation is completed, it is rolled and sent to a drying room for drying. The temperature of the drying room shall not exceed 70 degrees Celsius;

[0009] Then the added raw yarn is arranged. The deodorizing socks adopt a double-sided process, wherein the outer side adopts a mixed raw yarn, and the inner side adopts a blend of the mixed raw yarn and the added raw yarn. The socks made by the double-sided process are more wear-resistant than the socks made by the single-sided process, and are not easy to generate heat due to friction, and are not easy to cause sweat. The added raw yarn is blended and formed by cotton yarn fiber, spandex fiber, and plant fiber, and the mass fraction thereof accounts for 5-8:1-2:0.1-0.3. The plant cellulose is prepared by using nanmu bamboo, which is crushed and boiled in boiling water into a wood pulp state, and then the sugar and fat are washed, and the defatted cellulose is extracted to obtain the plant fiber. The bamboo quinones remaining in the plant fiber can effectively destroy the cell wall of bacteria and inhibit their reproduction, and the addition of pure natural fiber can avoid accidental injury to the beneficial bacteria in the deep epidermis and dermis of the skin, and can ensure that the skin surface is smooth, tender, elastic, and not dry.

[0010] The mixed raw yarn and the added raw yarn are used to knit socks through a fully automatic computer knitting machine, and then put into an acetic acid solution for steaming, the purpose of which is to soften the plant fiber in the knitted socks so that they have good flexibility to meet the requirements of fitting the feet. After the socks are steamed, they are heat-dried and then shaped by high-temperature and high-pressure steam.

[0011] The advantages and positive effects of the present invention are as follows: compared with the traditional bamboo fiber spinning process in which bamboo is dissolved in carbon disulfide and then washed with strong acid and strong alkali, the bamboo quinone content in the present process is higher and the pre-washing process makes it more resistant to washing; in addition, compared with the antibacterial socks using chemical antibacterial agents, the socks produced by the present process have better washing resistance, and can effectively inhibit the contamination and reproduction of bacteria after long-term friction with shoes and insoles, thereby inhibiting the occurrence of odor from the source; in addition, the addition of natural plant fibers on the side that contacts the skin reduces the irritation to the skin, and can adapt to more people with sensitive skin, keeping the skin surface smooth, tender, elastic and not dry.

[0013] Finishing of raw yarn: cotton yarn fiber, spandex fiber and viscose fiber are finished and blended into yarn in a mass fraction ratio of 8:1:1. The obtained yarn is called mixed raw yarn. The mixed raw yarn is then put into an impregnation tank for impregnation finishing. The impregnation liquid is a copolymer solution of new biopolymer 3-hydroxybutyrate and 3-hydroxyvalerate. The solution concentration is 7%. The impregnation temperature is controlled at 75 degrees Celsius. The impregnation is for 20 minutes. After the impregnation is completed, it is rolled and sent to a drying room for drying. The temperature of the drying room shall not exceed 70 degrees Celsius.

[0014] Then, the added raw yarn is arranged. The deodorizing socks adopt a double-sided process, wherein the outer side adopts a mixed raw yarn, and the inner side adopts a blended blend of the mixed raw yarn and the added raw yarn. The socks made by the double-sided process are more wear-resistant than the socks made by the single-sided process, and are not easy to generate heat due to friction or sweat. The added raw yarn is blended and formed by cotton yarn fiber, spandex fiber, and plant fiber, and the mass fraction thereof accounts for 5:1:0.1. The plant cellulose is prepared by using bamboo, which is crushed and boiled in boiling water into a wood pulp state, and then the sugar and fat are washed, and the defatted cellulose is extracted to obtain the plant fiber.

[0017] Embodiment 2:

[0018] Finishing of raw yarn: cotton yarn fiber, spandex fiber and viscose fiber are finished and blended into yarn in a mass fraction ratio of 5:1:1. The obtained yarn is called mixed raw yarn. The mixed raw yarn is then put into an impregnation tank for impregnation finishing. The impregnation liquid is a copolymer solution of new biopolymer 3-hydroxybutyrate and 3-hydroxyvalerate. The solution concentration is 10%. The impregnation temperature is controlled at 82 degrees Celsius and the impregnation time is 20 minutes. After the impregnation is completed, it is rolled and sent to the drying room for drying. The temperature of the drying room shall not exceed 70 degrees Celsius.

[0019] Then the added raw yarn is sorted. The deodorizing socks adopt a double-sided process, wherein the outer side adopts a mixed raw yarn, and the inner side adopts a blend of mixed raw yarn and added raw yarn. The socks made by the double-sided process are more wear-resistant than those made by the single-sided process, and are not easy to generate heat due to friction or sweat. The added raw yarn is blended and formed by cotton yarn fiber, spandex fiber, and plant fiber, and the mass fraction thereof accounts for 8:2:0.3. The plant cellulose is prepared by using nanmu bamboo, which is crushed and boiled in boiling water into a wood pulp state, and then the sugar and fat are washed, and the defatted cellulose is extracted to obtain the plant fiber. The bamboo quinones remaining in the plant fiber can effectively destroy the cell wall of bacteria and inhibit their reproduction, and the addition of pure natural fiber can avoid accidental injury to the beneficial bacteria in the deep epidermis and dermis of the skin, and can ensure that the skin surface is smooth, tender, elastic, and not dry.

[0020] The mixed raw yarn and the added raw yarn are used to knit socks through a fully automatic computer knitting machine, and then put into an acetic acid solution for steaming, the purpose of which is to soften the plant fiber in the knitted socks so that they have good flexibility to meet the requirements of fitting the feet. After the socks are steamed, they are heat-dried and then shaped by high-temperature and high-pressure steam.

[0021] Embodiment three;

[0022] The raw yarn is finished. After finishing the cotton yarn fiber, spandex fiber and viscose fiber, the yarn is blended into yarn in a mass fraction ratio of 9:1.6:1.2.

The impregnation liquid is a copolymer solution of a new biopolymer 3-hydroxybutyrate and 3-hydroxyvalerate. The solution concentration is 8%. The impregnation temperature is controlled at 80 degrees Celsius and the impregnation time is 20 minutes. After the impregnation is completed, it is rolled and sent to the drying room for drying. The temperature of the drying room shall not exceed 70 degrees Celsius.

[0023] Then the added raw yarn is sorted. The deodorizing socks adopt a double-sided process, wherein the outer side adopts a mixed raw yarn, and the inner side adopts a blend of the mixed raw yarn and the added raw yarn. The socks made by the double-sided process are more wear-resistant than the socks made by the single-sided process, and are not easy to generate heat due to friction or sweat. The added raw yarn is blended and formed by cotton yarn fiber, spandex fiber, and plant fiber, and the mass fraction thereof accounts for 6:1.6:0.25. The plant cellulose is prepared by using bamboo, which is crushed and boiled in boiling water into a wood pulp state, and then the sugar and fat are washed, and the defatted cellulose is extracted to obtain the plant fiber. The bamboo quinones still remain in the plant fiber, which can effectively destroy the cell wall of bacteria and inhibit their reproduction. The addition of pure natural fiber can avoid accidental injury to the beneficial bacteria in the deep epidermis and dermis of the skin, and can ensure that the skin surface is smooth, tender, elastic, and not dry.

[0024] After the mixed raw yarn and the added raw yarn are used to weave socks through a fully automatic computer knitting machine, they are then put into an acetic acid solution for steaming, the purpose of which is to soften the plant fiber in the knitted socks so that they have good flexibility to meet the requirement of fitting the feet. After the socks are steamed, they are heat-dried and then shaped by high-temperature and high-pressure steam. Compared with Examples 1 and 2, the socks made by this embodiment are better in elasticity, deformation resistance and wear resistance, the material cost is slightly increased, and the color fastness after coloring is slightly worse than that of Example 2 but better than that of Example 1.
