Description

Cool Tech cooling gel manufacturing and printing process

[0001] The present invention relates to the field of textile manufacturing and chemical printing on fabrics.

[0002] The production of jeans has been a manufacturing process since 1853, resulting in jeans with durable fabrics that have been on the market for approximately 170 years. During this time, denim fabrics have been developed and categorized into various types, but one type is specifically defined as denim, characterized by its thickness and exceptional durability.

[0003] However, despite over a hundred years of development and existence, denim jeans still have issues with their thickness and durability. These issues can cause discomfort for the wearer, especially in high-temperature areas, because the thick denim fabric retains heat and makes it uncomfortable.

[0004] To address this issue, jeans manufacturers have begun applying various chemicals that help reduce surface temperatures (substances that help reduce surface temperatures to the inner surface of the pants that contact the skin. The aim is to reduce the wearer's body temperature, resulting in less heat generated by wearing jeans. This approach has been adopted by jeans makers and has led to more people choosing to wear jeans. However, so far, printing surface temperature-reducing substances still face four major challenges.

[0005] The ability of surface temperature-reducing substances to stick to surfaces after washing or cleaning. According to the inventor's test results, when surface temperature-reducing substances are printed on the inner fabric of jeans, they perform well in the first few washes. However, after several washes, their ability to reduce temperature diminishes to the point where it appears as if the substances were never applied.

[0006] Besides the issue of adhesion to the fabric after cleaning, the second problem the inventor identified was a significantly reduced ability to produce results when applying surface temperature-reducing substances on thick fabrics like denim. Therefore, the application of surface temperature-reducing substances must be limited to the fabric's thickness and cannot be used on all types of fabric used in making jeans.

[0007] The third problem the inventor discovered was that when the surface cooling material was printed, the wearer experienced skin irritation, making wearing jeans with the surface cooling material uncomfortable.

[0008] The final issue the inventor faced was that producing jeans printed with the surface cooling agent was slow and in small quantities compared to conventional methods.

[0009] The inventor, therefore, experimented and researched to develop a process for producing and printing Cool Tech cooling gel, a substance that helps reduce surface temperature in one form. It was hoped that during this research, the process for making and printing Cool Tech cooling gel, according to this invention, would help solve various issues that arise when substances designed to lower surface temperature are printed on jeans.

[0010] The objective of this invention is to develop a process for printing substances that effectively reduce surface temperature for a long duration, are comfortable for the wearer, and can be produced in sufficient quantities for market sale. The process of producing and printing Cool Tech cool gel involves three steps: Printing (1), Hanging Dry (2), and Baking (3), which are defined as follows: In the printing step, a Screen Count no. 60 screen fabric is used, with a mold frame sized according to the fabric, and the printing is performed with a squeegee a total of four times per printing area on the fabric. The Hanging Drying process takes at least 2 hours but no more than 4 hours, and the Baking process maintains a constant temperature of 140 degrees Celsius with a heating period of 30 seconds on each side.

[0011] In one aspect, the fabric printed according to this invention is denim fabric, fabric of the same thickness, or fabric that is thinner than all types of denim fabric.

[0012] In another aspect, the total heating time of the fabric in the dryer must not be more than 1 minute.

[0013] In one aspect, the dryer used shall be either an oven conveyor dryer or another dryer with the same or similar heating capacity.

[0014] The purposes and features of this and other inventions will become clearer when considered along with the accompanying drawings and the most detailed description of the invention, which will be provided later.Fig.1

[0015] illustrates the manufacturing and printing process of Cool Tech cooling gel.

[0016] This invention will be described using illustrative drawings and references to these drawings for clarification and explanation purposes. Identical parts in these illustrations will be labeled with the same reference numbers without limitation, and the scope of the invention will be defined by the attached claims.

[0017] The manufacturing and printing of Cool Tech cooling gel will start once the denim fabric has been prepared for printing. Next, for preparing the screen fabric, the inventor will use Screen Count No. 60. After stretching the screen fabric on a mold frame that matches the size of the fabric to be printed, the inventor will begin screening by pouring a surface cooling agent onto one side of the screen fabric and pressing with a squeegee to make the agent adhere. The squeegee pressing will be done four times, and the entire printing process must be finished within 24 hours of completing the fabric preparation.

[0018] After printing with a screen printing plate, it enters the drying process by hanging (Hang Dry), which allows the substance that helps reduce surface temperature to dry and start adhering to the fabric. During this process, the inventor recommends drying for at least 2 hours but no more than 4 hours.

[0019] When the inventor determines that the time is up, they will transfer the fabric with the temperature-reducing substance into a hot air conveyor oven for drying, which is commonly used in factories that process textiles. In this step, the inventor will keep the oven temperature steady at 140 degrees Celsius and heat each side for 30 seconds before moving the fabric to storage and preparing it for distribution.

[0020] The results from following the manufacturing process and printing the Cool Tech cooling gel will have six positive effects on the processed jeans, as follows:

[0021] 1. The duration of the effectiveness in reducing the surface temperature of the substance that helps lower the temperature printed on the fabric can be demonstrated clearly and over a long period. After at least 20 washes, the specific heat capacity remains at 4.750 J / g, which is significantly longer than that of other similar inventions.

[0022] 2. The reduction in outer surface temperature efficiency of jeans is 2.2 degrees Celsius less compared to jeans of the same thickness that were not treated with the Cool Tech cooling gel process and printing.

[0023] 3. Jeans that undergo the Cool Tech cooling gel process and printing are less irritating than jeans printed with a surface temperature-reducing agent and made using the current process.

[0024] 4. The Cool Tech cooling gel process and printing process each have a heating time of only 30 seconds per side of the fabric, which is shorter than the current surface temperature reduction and printing processes.

[0025] 5. During an 8-hour work shift, the Cool Tech cooling gel and printing process can produce up to 1,900 pairs of jeans, which exceeds the output of the current process that uses a surface temperature reducing agent.

[0026] 6. The Cool Tech cooling gel process and printing method still demonstrate full efficiency when applied to thick denim fabrics, like denim, as well as thinner fabrics. This shows that the manufacturing and printing process of Cool Tech cooling gel can be used on both thin and thick fabrics.

[0027] Although the present invention is fully described here along with the attached drawings as examples, it is understood that modifications or changes by a person skilled in the art and science, in accordance with the nature of the invention set forth in the appended claims, may include aspects of the invention that, although not specifically stated in the claims, are useful and produce results similar to those of the invention described in the claims.Best Mode
