Description

Technical Field

[0001] The invention relates to the technical field of sweatshirts, in particular to a moisture absorbing and perspiration wicking sweatshirt and a processing technology thereof. Background Art

[0002] Sweatshirts are a type of casual sportswear that originated in New York, USA in the 1930s. Initially, they were designed to be workwear for cold storage workers at the time. Because of their comfort and warmth, they were gradually favored by athletes, rugby players, and music stars, and then became popular all over the world. Sweatshirts are generally loose and casual, combining fashion and functionality, and combining comfort and fashion. They are very popular among customers in the casual wear category, and have gradually become the first choice for young people in street sports.

[0003] For example, the patent document with the publication number CN114304797A discloses an improved sweater and its preparation process. The sweater has the advantage of good thermal insulation performance. When warming people's hands, the temperature inside the pockets can be increased, thereby increasing the temperature of people's hands and reducing the feeling of coldness. Moreover, the electric hot water bag is not only easy to disassemble and assemble, but also the damaged electric hot water bag can be repaired and maintained, thereby improving the thermal insulation performance. In addition, it has a waterproof function. When water is spilled on the outside of the sweater body, the water flows downward along the waterproof layer and the pockets, reducing the contact between the water and the body and the inside of the pockets, thereby reducing the occurrence of the body and the inside of the pockets being wetted by water, thereby improving the thermal insulation performance.

[0004] However, as a casual sportswear, the moisture absorption and perspiration wicking performance of sweatshirts is crucial to wearing comfort. During exercise or in a high temperature environment, the human body sweats easily. If the sweatshirt cannot effectively absorb and discharge sweat, the sweat will remain on the skin, causing an increased stickiness, thus affecting the wearing comfort. Moreover, sweat remaining on the skin will also provide an environment for bacteria to grow, increasing the risk of skin infection. If a sweatshirt with poor moisture absorption and perspiration wicking performance is worn for a long time, the bacteria and microorganisms in the sweat will multiply on the clothing, thus producing odor.

[0005] Therefore, it is urgent to improve this shortcoming. The present invention studies and improves the existing structure and shortcomings, and provides a moisture wicking sweatshirt and a processing technology thereof. Summary of the invention

[0014] Furthermore, the cloth blocking assembly includes a shielding cotton cloth and a side zipper, the left and right sides of the shielding cotton cloth are provided with side zippers, one side of the side zipper is sewn and connected to the main garment body, and the left and right sides of the shielding cotton cloth are connected to the back of the main garment body through the side zipper.

[0015] Furthermore, the cloth blocking assembly also includes a Velcro sub-surface and a snap-on mother component. The Velcro sub-surface is sewn on one side of the blocking cotton cloth close to the main garment body, and both sides of the blocking cotton cloth are fixedly connected with the snap-on mother components.

[0016] Furthermore, the number of the binding cloth belts is two, and the two binding cloth belts are symmetrically arranged on the back of the pure cotton sweatshirt, and the binding cloth belts are connected to the shielding cotton cloth through the male and female snap buckles.

[0017] On the other hand, a process for processing a moisture wicking sweatshirt is provided, which is applied to the moisture wicking sweatshirt as described above, and comprises the following steps:

[0018] S1. According to the design drawing of the sweatshirt, use a cutting device to cut the pure cotton fabric into the shapes of the main body, pockets, sleeves and hood, and cut the gauze cotton fabric into the shapes of the first gauze cotton lining and the second gauze cotton lining;

[0019] S2, cutting out ventilation grooves on the sleeves, and cutting out ventilation grooves on the left and right sides of the main garment body, and then using an automatic sewing machine to sew the first gauze cotton lining to the inner side of the ventilation groove, and sew the second gauze cotton lining to the inner side of the ventilation groove;

[0020] S3, cutting a notch on the back of the main garment body in the shape of the linen shoulder cloth, and sewing the linen shoulder cloth at the notch;

[0021] S4, cutting the modal cotton fabric, the silk fabric, and the cotton yarn fabric into the shape of a composite cloth in sequence to obtain a modal cotton layer, a silk fabric layer, and a cotton yarn layer, and then sewing the three layers of fabric into a composite cloth, and then cutting out ventilation holes on the composite cloth, and sewing a Velcro mother surface on one side of the composite cloth, and then cutting out a notch on the back of the main garment body according to the shape of the composite cloth, and sewing the linen shoulder cloth at the notch position;

[0025] The present invention provides a moisture absorbing and perspiration wicking sweatshirt and a processing technology thereof, which has the following beneficial effects:

[0026] 1. The present invention cuts out ventilation grooves on the sleeves and sews a first gauze cotton lining. Similarly, ventilation grooves are cut out on the main body of the garment and a second gauze cotton lining is sewn. The holes of the gauze cotton fabric are significantly larger than those of the pure cotton fabric, and the thickness is significantly thinner than that of the pure cotton fabric, so as to achieve a good ventilation and heat dissipation effect, so that the moisture emitted by the human body is not easily accumulated inside the sweatshirt.

[0027] 2. The present invention focuses on improving the back of the sweatshirt. Not only is a large area of ​​linen shoulder cloth sewn thereon, which utilizes the large holes and high sweat absorption of the linen shoulder cloth to promote moisture absorption and sweat discharge from the wearer's back, but also a composite cloth is sewn thereon.
