[0002] Down jackets are a type of clothing filled with down fillings. They are light, soft, and warm, and are indispensable for people in winter. Most existing down jackets are made by preparing garment pieces, sewing down cavities, filling, sealing, and connecting. However, due to the sewing of down cavities, most down jackets have the disadvantage of too much down penetration.

[0003] Steel stamped hot pressing lines can effectively solve the above problems, but the traditional hot pressing gluing process is not only rough in appearance but also inconvenient to operate, which limits the application of hot pressing gluing process in the preparation of down jackets.

[0004] Therefore, it is of great value to develop a method for preparing anti-drilling fleece clothing sheets using a hot pressing line process that is anti-drilling fleece, has a smooth appearance and fine indentations. Summary of the invention

[0036] Unless otherwise specified, the raw materials involved in the following specific embodiments are all conventional materials in the art and can be purchased from commercial products.

[0037] Example 1

[0038] A method for preparing anti-drilling fleece sheet by hot pressing line process, the process flow chart is as follows Figure 1 As shown, the following steps are included:

[0039] A three-in-one floating yarn base is selected as the fabric 1 and a floating yarn liner cloth is selected as the liner material 2, and glue (the glue is conventionally commercially available) is brushed on the liner material 2 at intervals of 3 cm to form spaced glue strips 3, and the width of each glue strip 3 is about 0.9 cm;

[0040] Start the high-frequency plastic welding machine, and the main machine will heat the upper copper mold first. Set the temperature of the upper copper mold to 200°C to achieve the matching strength between the fabric 1 and the rubber strip 3;

[0041] Fix the liner material 2 containing the spaced rubber strips 3 on the lower copper mold of the high-frequency plastic welding machine, and lay the fabric 1 on the liner material 2, aligning the two in the center, and then move the lower copper mold into the main unit of the high-frequency plastic welding machine, start the high-frequency plastic welding machine, the output current of the high-frequency plastic welding machine is 60A, and the upper copper mold and the lower copper mold are pressed together at a temperature of 200°C and an air pressure of 6kg to form an indentation 4 with a width of 0.5mm to obtain the anti-drilling fleece piece.

[0042] Visually observe the anti-drilling fleece sheet prepared by the method provided in Example 1, and obtain the physical picture of the anti-drilling fleece sheet obtained in Example 1 as shown below: Figure 2 As shown;

[0043] from Figure 2 It can be seen that the surface of the anti-drilling fleece sheet provided in Example 1 is very flat and beautiful, and the indentations are delicate, which can effectively prevent water, air, pollutants, etc. from penetrating from the indentations.

[0044] Example 2

[0045] A method for preparing an anti-drilling fleece sheet by using a hot pressing line process, which is different from Example 1 only in that the pressing temperature is 160° C., and the other steps, conditions and parameters are the same as those in Example 1.

[0046] Similarly, visual observation of the anti-drilling fleece sheet prepared by the method provided in Example 2 shows that the surface of the anti-drilling fleece sheet prepared by the method provided in Example 2 is also very flat and beautiful, and the indentations are delicate, which can effectively prevent water, air, pollutants, etc. from penetrating from the indentations.

[0047] Example 3

[0048] A method for preparing an anti-drilling fleece sheet by using a hot pressing line process, which is different from Example 1 only in that the pressing temperature is 300° C., and the other steps, conditions and parameters are the same as those in Example 1.

[0049] Similarly, visual observation of the anti-drilling fleece sheet prepared by the method provided in Example 3 shows that the surface of the anti-drilling fleece sheet prepared by the method provided in Example 3 is also very flat and beautiful, and the indentations are delicate, which can effectively prevent water, air, pollutants, etc. from penetrating from the indentations.

[0050] Example 4

[0051] A method for preparing an anti-drilling fleece sheet by using a hot pressing line process, which is different from Example 1 only in that the pressing temperature is 100° C., and the other steps, conditions and parameters are the same as those in Example 1.

[0052] Similarly, visual observation of the anti-drilling fleece sheet prepared by the method provided in Example 4 shows that the surface of the anti-drilling fleece sheet prepared by the method provided in Example 4 is also very flat and beautiful, and the indentations are delicate. However, since the pressing temperature is too low (100°C), the adhesive strip cannot be firmly attached to the fabric, and the sealing at the indentation is poor, which makes it easier for fleece to drill in and run away.

[0053] Example 5

[0054] A method for preparing an anti-drilling fleece sheet by using a hot pressing line process, which differs from Example 1 only in that the pressing temperature is 350° C., and the other steps, conditions and parameters are the same as those in Example 1.

[0055] Similarly, visual observation of the anti-drilling fleece sheet prepared by the method provided in Example 5 shows that the surface flatness of the anti-drilling fleece sheet prepared by the method provided in Example 5 is poor, which is caused by the excessively high pressing temperature.

[0056] Application Example 1

[0057] A down-proof clothing comprises the down-proof clothing piece provided in Example 1 and down, wherein the down is filled in a sandwich space formed by a fabric material and a bile material of the down-proof clothing piece.

[0058] Visually observe the anti-drilling down clothing provided in Application Example 1, and obtain the actual picture of the anti-drilling down clothing provided in Application Example 1 as shown below: Figure 3 As shown;

[0059] from Figure 3 It can be seen that the anti-drilling down clothing prepared by the anti-drilling down clothing sheet prepared by the method provided in Example 1 is more technological and high-quality in visual effect, and no down drilling phenomenon occurs.

[0060] The applicant declares that the present invention uses the above-mentioned embodiments to illustrate a method for preparing an anti-drilling fleece sheet, an anti-drilling fleece sheet and an anti-drilling fleece garment by a hot pressing line process, but the present invention is not limited to the above-mentioned embodiments, that is, it does not mean that the present invention must rely on the above-mentioned embodiments to be implemented.
