Description

Technical Field

[0001] The present invention relates to the technical field of health care socks, in particular to a pair of socks for preventing dry feet and foot cracks and a preparation method thereof. Background Art

[0002] In the technical field of health care socks, it is a common technical means to endow socks with health care functions such as preventing dry feet and foot cracks by using a latex solution with a specific formula. For example, a latex solution containing specific components is coated on the surface of the fabric and processed into health care socks, which to a certain extent meets the needs of consumers for foot care.

[0003] However, there are obvious defects in such existing technologies. In terms of the latex solution, the original latex solution formula has poor stability during storage and use. Over time, the phenomena of emulsion layer separation and water-emulsion separation will inevitably occur, resulting in a significant decrease in the viscosity of the latex solution. This not only makes it difficult for the latex solution to adhere evenly to the fabric during the coating process, affecting the stability of the production process and the consistency of the product, but also reduces the protective performance of the health care socks, shortens the effective service life of the product, increases production costs and resource waste.

[0004] In the white cloth treatment process, the traditional method usually directly uses the purchased white cloth without shrinkage treatment, and only irons out the wrinkles and then performs cutting, gluing and pasting operations. This treatment method ignores the shrinkage characteristics of the white cloth during subsequent washing, resulting in serious shrinkage and deformation problems of the made health care socks once they are washed during wearing. This not only affects the aesthetics of the socks, but also reduces the wearing comfort and fit, greatly affecting the user experience of consumers.

[0005] Therefore, the deficiencies in the latex solution stability and white cloth treatment effect of the existing health care socks and their preparation methods need to be urgently improved through technological innovation to enhance product quality and market competitiveness.

For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on these drawings. Among them:

[0026] Figure 1 It is a schematic diagram of the overall structure in the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0027] To make the above objects, features, and advantages of the present invention more apparent and understandable, the following provides a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings of the specification.

[0028] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention may be practiced in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the spirit of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0029] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they separate or alternative embodiments that are mutually exclusive of other embodiments.

[0030] Example 1

[0031] Specifically, for the preparation of the latex solution: In a clean stirring container, weigh 60% natural latex, 0.3% vitamin C, 0.3% vitamin E, 0.6% aloe vera gel, 3% carrageenan, and 36% soft water by mass percentage. Use an electric stirrer to stir at a speed of 200 revolutions per minute for 15 minutes to fully mix the components and form a uniform basic latex solution. At this time, observe the basic latex solution, which has a delicate texture and no obvious particulate matter.

[0032] Latex solution aging treatment: Slowly pour 5% carrageenan aqueous solution (by mass of the basic latex solution) into the basic latex solution, and continuously stir at a speed of 150 revolutions per minute for 5 minutes to ensure preliminary uniform mixing of the two. Subsequently, seal the mixture and place it in a constant temperature and humidity environment at 25°C and 50% relative humidity for 50 minutes to allow the carrageenan aqueous solution and the basic latex solution to fully dissolve and age with each other, forming a new latex solution. After aging is completed, the new latex solution presents a homogeneous and stable state without layering or precipitation.

[0033] Pretreatment of white cloth: Select uncut pure cotton white cloth and completely immerse it in a large basin of water at a temperature of 36°C, ensuring that the white cloth is completely submerged by the water. During the soaking process, gently turn the white cloth every 2 hours to allow all parts to fully contact the water. After 12 hours of soaking, take out the white cloth, gently squeeze out the excess water by hand, and then hang it in a well-ventilated and light-proof indoor space to dry naturally. During the drying process, turn the white cloth once in the morning and once in the evening every day. After 48 hours, the white cloth is completely dry, and the fabric surface is flat without obvious wrinkles.

[0034] Gluing and Shaping: The dried white cloth is precisely cut according to the pre-designed health sock pattern to obtain the required cloth pieces. Using a special gluing device, a new latex solution is coated on the surface of the cloth pieces with a uniform thickness, and the gluing thickness is controlled at 0.3 mm. After gluing, the cloth pieces are combined according to a specific pasting process to form the prototype of the health sock. Finally, the health sock is placed in an ironing device and ironed at a temperature of 130 °C for 4 minutes to make the shape of the health sock more regular and the surface smoother.

[0035] Example 2

[0036] Specifically, latex solution preparation: Weigh 80% natural latex, 0.4% vitamin C, 0.4% vitamin E, 0.7% aloe vera gel, 4% carrageenan, and 14.5% soft water. Add these components into a reaction kettle with heating and stirring functions in sequence. First, turn on the stirring function, set the rotation speed to 180 revolutions per minute, and at the same time raise the temperature in the reaction kettle to 30 °C and continuously stir for 20 minutes to obtain the basic latex solution. At this time, the basic latex solution has good fluidity and uniformity.

[0037] Latex solution aging treatment: Add 5% carrageenan aqueous emulsion by mass to the basic latex solution, increase the stirring speed to 220 revolutions per minute, and stir for 8 minutes to fully mix the two. Then seal the reaction kettle and let it stand for 45 minutes at a temperature of 28 °C for aging. During the aging process, observe the state of the latex solution every 15 minutes to ensure no abnormal changes. After aging, the new latex solution has a moderate viscosity and good stability.

[0038] Pre-treatment of white cloth: For the already cut and shaped white cloth pieces, use high-density white towels with excellent water absorption to wrap the white cloth pieces in layers, and then apply uniform pressure to squeeze out as much moisture as possible from the white cloth pieces. After squeezing, neatly place the white cloth pieces on a clean stainless steel workbench, and a layer of clean cotton cloth is pre-laid on the workbench. Place the workbench in an indoor environment at a temperature of 22 °C and a relative humidity of 45% to dry naturally. During the drying process, turn the white cloth pieces over every 3 hours. After 36 hours, the white cloth pieces reach a completely dry state, and the size of the cloth pieces is stable without obvious shrinkage or deformation.

[0039] Gluing and shaping: By means of manual gluing, evenly apply the new latex liquid on the surface of the white cloth piece to ensure even gluing without omission. After gluing, paste and combine each white cloth piece according to the design requirements to form a health care sock. Specifically, the prepared new latex liquid is manually applied on the cut white cloth piece, and then pasted on the mold with the reverse side of the sock. It will naturally dry to form an anti-cracking film. It should be noted that no machine equipment is used here. Only finished socks, molds (which can be wooden or hard plastic), and white cloth pieces are needed. A person uses a glass rod to dip the latex liquid and apply 0.2 mm of latex liquid on the white cloth piece. Place the pasted sock mold on the workbench and let it dry naturally. After the latex liquid dries, it will naturally become an anti-cracking film. At this time, the ordinary sock will become a health care sock after such processing, and the manufacturing cost of this method is lower.

[0040] Example 3,

[0041] Specifically, latex liquid preparation: Accurately weigh 90% natural latex, 0.45% vitamin C, 0.45% vitamin E, 0.75% aloe vera gel, 4.5% carrageenan, and 8.5% soft water. Pour all the ingredients into a vacuum stirring container and stir at a speed of 250 revolutions per minute for 25 minutes under the condition of a vacuum degree of -0.08 MPa to obtain the basic latex liquid. Stirring in a vacuum environment effectively reduces the generation of bubbles in the latex liquid, making the basic latex liquid purer and more uniform.

[0042] Latex liquid aging treatment: Add 5% carrageenan aqueous emulsion by mass to the basic latex liquid, close the vacuum system, continue to stir at a speed of 200 revolutions per minute for 10 minutes, then transfer the latex liquid to a sealed container and let it stand for 55 minutes at a temperature of 23°C for aging. After aging, all the performance indicators of the new latex liquid reach the ideal state and have good coating performance.

[0043] It should be noted that 5% carrageenan is an aqueous emulsion prepared from 5 grams of carrageenan and 100 grams of soft water, and this aqueous emulsion is added to the latex liquid.

[0044] Pre-treatment of white cloth: Put the white cloth before cutting into a large soaking pool with a water temperature of 37°C. An appropriate amount of softener is pre-added to the soaking pool to improve the softness of the white cloth. After soaking for 11 hours, take out the white cloth, put it into a centrifuge and spin-dry it at a speed of 800 revolutions per minute for 3 minutes to remove most of the water. Then spread the white cloth flat on a well-ventilated drying rack and let it dry naturally under the conditions of an ambient temperature of 23°C and a relative humidity of 55%. During the drying process, adjust the position and angle of the drying rack in a timely manner according to the drying situation of the white cloth to ensure uniform drying of the white cloth. After 40 hours, the white cloth is completely dry, and the fabric feels soft and the surface is flat.

[0045] Gluing and forming: Using an automated gluing production line, a new latex solution is evenly coated on the dried white cloth. The gluing speed is controlled at 10 meters per minute, and the gluing thickness is 0.25 millimeters. The glued white cloth passes through a high-temperature drying tunnel and is dried for 2 minutes at a temperature of 80 °C to preliminarily cure the latex solution. Then, according to the forming process of the health socks, the white cloth is folded, pasted, sewn, etc. to make health socks. Finally, the health socks are ironed for a second time at an ironing temperature of 120 °C for 5 minutes to further improve the quality and appearance of the health socks.

[0046] Comparative experiment

[0047] In order to more intuitively reflect the advantages of the preparation method of the present invention, the following comparative experiments were carried out:

[0048] Experiment 1: Comparison of latex solution stability

[0049] Control group: According to the existing latex solution formula and preparation method, prepare the latex solution without carrying out the aging treatment of the carrageenan aqueous emulsion.

[0050] Experimental group: Use the latex solution preparation method and aging treatment steps of Example 1 of the present invention to prepare the latex solution.

[0051] The latex solutions of the control group and the experimental group are respectively filled into the same sealed containers and placed in an environment with a temperature of 25 °C and a relative humidity of 50%. Observe the state of the latex solution every 24 hours and record as follows:

[0052] Day 1: There are no obvious changes in the latex solutions of the control group and the experimental group.

[0053] Day 3: Slight stratification begins to appear in the latex solution of the control group, with the upper layer being thinner and the lower layer being slightly thicker; the latex solution of the experimental group still maintains a uniform and stable state.

[0054] Day 7: The stratification of the latex solution in the control group is obvious, with a clear boundary between the upper and lower layers, and a small amount of precipitation appears; only a very slight stratification sign appears in the latex solution of the experimental group, and it can be restored to uniformity with a little stirring.

[0055] Day 15: The stratification of the latex solution in the control group is severe and it cannot be used normally; the latex solution of the experimental group can still be used normally, but the viscosity has decreased slightly.

[0056] Experiment 2: Comparison of the appearance of the socks after washing

[0057] Control group: Use white cloth that has not been physically shrunk and make health socks according to the method of the original patent.

[0058] Experimental group: Use the white cloth pretreatment method and preparation process of Example 2 of the present invention to make health socks.

[0059] The health socks of the control group and the experimental group were respectively subjected to 10 standard washes (washing temperature 40°C, using ordinary laundry detergent, washing time 30 minutes, dehydration speed 1000 revolutions per minute). The results after washing are as follows:

[0060] Obvious shrinkage occurred in the health socks of the control group, with many folds on the fabric surface, and the size of the socks changed significantly, the length shortened by about 10%, and the width narrowed by about 8%.

[0061] The health socks of the experimental group remained basically flat, with only slight folds, and could be restored to their original state by simple ironing. The size change of the socks was extremely small, and the changes in length and width were both within 2%.

[0062] Through the above rich examples and comparative experiments, it can be fully proved that the preparation method of the present invention has significant advantages in terms of the stability of the latex solution and the quality of the finished socks, can effectively solve the problems existing in the prior art, and has good practicability and popularization value.

[0063] Finally, it should be pointed out that the methods and devices described in detail above are only examples, and those skilled in the art can modify these examples in different ways as long as they do not depart from the scope of the present invention.
