Description

Technical Field

[0001] This application relates to the field of textiles, and more specifically, to a cooling vest with a breast-supporting effect. Background Technology

[0002] A vest is a sleeveless top that provides a cool and comfortable feel when worn in the hot summer.

[0003] Currently, to enhance the coolness of summer wear, vests on the market are usually made from knitted fabrics of cooling fibers, such as nylon, mica modified fibers, and Tencel fibers. These fabrics are cut and sewn together to create a cooling effect. They are also designed in styles such as tank tops, wide-necked vests, and wide-sleeved vests to further enhance the cooling sensation. However, in actual wear, the relatively wide cuffs of these vests reduce their effectiveness in concealing underarm fat, thus decreasing their overall applicability. Summary of the Invention

[0004] To address the issue that conventional cooling vests have a low effect on reducing the side breast area, thus limiting their applicability, this application provides a cooling vest with a side breast area reduction effect.

[0005] This application provides a cooling vest with the effect of reducing the appearance of underarm fat, using the following technical solution:

[0006] A cooling vest with side breast reduction effect includes a vest body with cuffs. The top and bottom of the cuffs are concave inward towards the central axis of the vest body to form an arc-shaped cuff edge. The angle between the bottom of the arc-shaped cuff edge and the horizontal line where the bottom of the arc-shaped cuff edge is located is 30-60°. The distance between the horizontal line where the top of the cuff is located and the horizontal line where the bottom of the cuff is located is 17-18cm. The difference between the minimum distance from the bottom of the cuff to the central axis of the vest body and the minimum distance from the top of the cuff to the central axis of the vest body is 6.5-7.5cm. The vest body is made of cooling fabric through cutting and sewing. The cooling fabric is knitted from yarn woven from 40-50% Lenzing Modal, 40-50% cotton and 5-15% spandex.

[0007] By adopting the above technical solution, controlling the angle between the bottom of the curved cuff and the horizontal line where the bottom of the curved cuff is located, and combining the horizontal distance from the top to the bottom of the cuff, as well as the difference between the minimum distance from the bottom of the cuff to the central axis of the vest body and the minimum distance from the top of the cuff to the central axis of the vest body, the resulting cuff can stably fit the human body's accessory breast area, achieving a good accessory breast reduction effect. At the same time, using a cooling fabric containing Lenzing Modal enhances the cooling sensation and comfort of wearing it. The cooling vest of this application not only has a good accessory breast reduction effect but also a good cooling sensation, making it more versatile than existing cooling vests.

[0008] Preferably, the curved cuff edge is provided with a binding edge, the width of which is 1.2-2.5cm.

[0009] By adopting the above technical solution, the curved cuff edge has a certain thickness and support, further improving the effect of concealing the underarm fat at the cuff.

[0010] Preferably, the outer surface of the vest body is provided with a first herringbone line and a second herringbone line at an angle corresponding to the chest area. The first herringbone line and the second herringbone line are parallel and spaced apart. The first end of the first herringbone line extends to the middle of one cuff and the second end of the first herringbone line extends to the bottom of the other cuff. The first end of the second herringbone line extends to the bottom of one cuff. The distance between the first herringbone line and the second herringbone line is 11-13cm.

[0011] By adopting the above technical solution, the first end of the second herringbone line is set below the bottom of one side of the cuff, so that when the human body wears the cooling vest, the second end of the first herringbone line and the first end of the second herringbone line extend to the position corresponding to the armpit on the side of the human body, which can play a good supporting and shaping role for the cuff, further enhancing the effect of reducing the underarm fat. In addition, the first herringbone line and the second herringbone line also have the effect of enhancing the bust shape, better highlighting the bust line.

[0012] Preferably, the distance between the horizontal line where the second end of the first herringbone thread is located and the horizontal line where the bottom of the cuff is located is equal to the distance between the horizontal line where the first end of the second herringbone thread is located and the horizontal line where the bottom of the cuff is located.

[0013] By adopting the above technical solution, the second end of the first herringbone and the first end of the second herringbone are symmetrically positioned in the horizontal direction corresponding to the central axis of the vest body, which further improves the stable support performance of the cuffs and further enhances the stability of the underarm area.

[0014] Preferably, the yarn is a cooling yarn, which is obtained by treating with a cooling agent, and the cooling agent is obtained from the following raw materials in parts by weight:

[0015]

[0016] By adopting the above technical solution, since the structure of the cooling vest with the function of supporting the underarm has good coverage for the underarm and armpit areas of the human body, the feeling of stuffiness increases after wearing the cooling vest with the function of supporting the underarm. Therefore, on this basis, the cooling fabric for preparing the cooling vest with the function of supporting the underarm is further modified to further improve the cooling sensation of the fabric. Specifically, the yarn is treated with cooling, and the cooling fabric is knitted using the yarn treated with cooling to make the cooling vest, thereby improving the wearing comfort.

[0017] Among them, the cooling agent has a good cooling effect. Under the synergistic effect of the film-forming agent, stabilizer, and crosslinking agent, the cooling agent is uniformly emulsified and dispersed in the solvent. The softener has antistatic and softening effects. Thus, a cooling treatment agent with good dispersion and adhesion is prepared. Cooling fabrics made from cooling yarns treated with this cooling treatment agent have good cooling stability and softness. It is suitable for preparing the cooling vest with side breast reduction effect of this application. The cooling vest made in this way has good cooling effect and good side breast reduction effect, does not produce a stuffy feeling, and has high applicability.

[0018] Preferably, the cooling agent is composed of xylitol, nanoscale molecular sieve and menthol, and the weight ratio of xylitol, nanoscale molecular sieve and menthol is 1:(5-5.5):(0.1-0.2).

[0019] By adopting the above technical solution, using nanoscale molecular sieves as adsorbents to adsorb xylitol and menthol, xylitol and menthol are released evenly to provide a cooling sensation. At the same time, due to the porous structure of the nanoscale molecular sieves, heat dissipation channels are formed in the fiber gaps of the cooling yarn, further improving the heat dissipation performance and cooling sensation of the obtained cooling fabric, thereby producing a cooling vest with a better cooling sensation.

[0020] Preferably, the film-forming agent is composed of hydroxypropyl methylcellulose and trimethylsiloxysilicate, wherein the weight ratio of hydroxypropyl methylcellulose to trimethylsiloxysilicate is (0.2-0.3):1.

[0021] By adopting the above technical solution, hydroxypropyl methylcellulose is a bio-based organic film-forming agent. The molecular structure of trimethylsiloxysilicate contains two different silicon atoms, one of which is replaced by three methoxy groups and the other by one hydroxyl group. This structure gives trimethylsiloxysilicate both the characteristics of organic matter and the stability of inorganic matter. By compounding hydroxypropyl methylcellulose and trimethylsiloxysilicate in a better ratio, the dispersion performance of the cooling agent can be improved, and the adsorption performance of the cooling agent on the yarn can also be improved, thereby improving the cooling stability of the obtained cooling vest.

[0022] Preferably, the crosslinking agent is composed of polyethylene glycol diglycidyl ether and silane coupling agent KH550, and the weight ratio of polyethylene glycol diglycidyl ether to silane coupling agent KH550 is (0.2-0.4):1.

[0023] By adopting the above technical solution, using polyethylene glycol diglycidyl ether and silane coupling agent KH550 in a better ratio as crosslinking agents, it is possible to improve the dispersion uniformity of the cooling agent and cooling treatment agent system, while also improving the bonding stability between the cooling treatment agent and the yarn, thereby improving the cooling stability of the obtained cooling vest.

[0024] Preferably, the stabilizer is composed of polysorbate-20 and ammonium acryloyldimethyl taurate / VP copolymer, wherein the weight ratio of polysorbate-20 to ammonium acryloyldimethyl taurate / VP copolymer is 1:(0.5-0.6).

[0025] By adopting the above technical solution, polysorbate-20 is an emulsifier with good stability, and ammonium acryloyl dimethyl taurate / VP copolymer is a high molecular surfactant-acrylic polymer with good dispersibility. When polysorbate-20 and ammonium acryloyl dimethyl taurate / VP copolymer are compounded in a better ratio, the two have a good synergistic effect, which can improve the system stability and emulsification dispersion stability of the obtained cooling treatment agent. The cooling fabric obtained in this way has good cooling stability.

[0026] Preferably, the cooling yarn is prepared by the following steps:

[0027] The cooling agent is diluted to prepare a 10-20 wt% cooling agent aqueous solution. The yarn is then immersed in the cooling agent aqueous solution, and the water bath ratio of the yarn to the cooling agent aqueous solution is controlled to be 1:(11-15). After immersion, dehydration, and steaming, the yarn is then washed and dried to obtain the cooling yarn.

[0028] By adopting the above technical solution, the yarn is soaked in a diluted cooling agent solution, allowing the yarn to be fully soaked and absorb the cooling agent solution. Then, the excess cooling agent solution is drained by dehydration. Next, the soaked cooling yarn is steamed using a steaming process to set the cooling yarn and improve its texture. Finally, the yarn is washed and dried to obtain the cooling yarn. The resulting cooling yarn has good cooling sensation and washability.

[0029] In summary, this application has the following beneficial effects:

[0030] 1. This application discloses a cooling vest with the effect of reducing underarm fat. By controlling the vertical distance from the top to the bottom of the cuff and the horizontal distance difference between the top and bottom of the cuff and the central axis of the vest body, and by controlling the angle between the bottom of the cuff and the horizontal line where the bottom of the cuff is located, the cuff can stably fit the underarm fat and armpit areas of the human body. At the same time, the cooling fabric is used, which has a good effect of reducing underarm fat and also has a good cooling sensation.

[0031] 2. By setting the first and second herringbone lines, the second end of the first herringbone line and the first end of the second herringbone line are symmetrically set in the horizontal direction corresponding to the central axis of the vest body. When worn, it can provide better support and shaping for the cuffs, further improving the effect of reducing side breast fat.

[0032] 3. By using a cooling agent to treat the yarn to produce a cooling yarn, the cooling yarn is then knitted into a cooling fabric. The cooling fabric is then cut and sewn to obtain the cooling vest with the side breast-reducing effect of this application, which reduces the stuffiness of the cuffs. While having a good side breast-reducing effect, it further enhances the coolness and comfort of the cooling vest and has a wide range of applications. Attached Figure Description
