[0018] Figure 1 This is a schematic diagram of the layered structure of cotton batting;
[0019] Figure 2 This is a schematic diagram of preferred embodiment 1 of the present invention;
[0020] Figure 3 This is a schematic diagram of preferred embodiment 2 of the present invention. Detailed Implementation
[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the utility model will be further described below in conjunction with the accompanying drawings.
[0022] Reference Figure 1 , Figure 2 and Figure 3 A washable cotton quilt, including the cotton wadding and the quilt cover. The cotton wadding is filled inside the quilt cover.
[0023] Regarding cotton quilts
[0024] From top to bottom, the layers are: top layer 1, middle layer 2, and bottom layer 3. Figure 1As shown. The upper layer 1, middle layer 2, and lower layer 3 are stacked in sequence and then connected by quilting.
[0025] The upper layer 1 is a wadding made of a blend of water-repellent cotton fibers and long-staple cotton fibers. The length of the water-repellent cotton fibers is 26-29 mm. Water-repellent cotton fibers are existing fibers, cotton fibers that have undergone water-repellent treatment, and can be purchased directly from the market. The moisture absorption of water-repellent cotton fibers is lower than that of normal cotton fibers. This invention uses an upper layer 1 with added water-repellent cotton fibers, which helps to improve the wash resistance of the upper layer 1.
[0026] The middle layer 2 is a wadding made of a blend of long-staple cotton fibers and fluffy cotton fibers. Both long-staple cotton fibers and fluffy cotton fibers are existing fibers and can be purchased directly from the market. The needle-punching density of the middle layer 2 is greater than that of the upper layer 1 and the lower layer 3. The length of the long-staple cotton fibers is 28-34 mm, and the length of the fluffy cotton fibers is approximately 22-25 mm. The lower layer 3 is a wadding made of a blend of water-repellent cotton fibers and long-staple cotton fibers. The length of the water-repellent cotton fibers is 26-29 mm. Water-repellent cotton fibers are cotton fibers that have undergone water-repellent treatment, and their moisture absorption is reduced compared to normal cotton fibers. This invention uses a lower layer 3 with added water-repellent cotton fibers, which helps to improve the wash resistance of the lower layer 3.
[0027] Specific Implementation Example 1 - Summer Quilt
[0028] The needle density in the middle layer is 80-100 needles / cm². 2 The needle-punching depth is 1-2 mm, and it is made of long-staple cotton fibers and fluffy cotton fibers evenly combed in a ratio of (40-60):(60-40), with a weight of 60-80 g / m². 2 The needle density in the upper layer 1 and lower layer 3 is 140-160 needles / cm². 2 The needle-punching depth is 1-2 mm, and it is made of water-repellent cotton fiber and long-staple cotton fiber mixed and combed in a ratio of (20-30):(70-80), with a basis weight of 25-35 g / m². 2 .
[0029] Specific Implementation Example 2 - Spring and Autumn Quilt
[0030] The needle density in the middle layer is 60-80 needles / cm². 2 The needle-punching depth is 5-6mm, and it is made of long-staple cotton fibers and fluffy cotton evenly combed in a ratio of (40-60):(60-40), with a weight of 130-150g / m². 2 The needle density in the upper layer 1 and lower layer 3 is 100-120 needles / cm². 2 The needle-punching depth is 7-8 mm, and it is made of water-repellent cotton fiber and long-staple cotton fiber mixed and combed in a ratio of (20-30):(70-80), with a weight of 100-110 g / m². 2 .
[0031] The washable cotton from Specific Examples 1 and 2 will now be subjected to a washing test. In both examples, the water-repellent cotton fiber used is No. 0217 water-repellent cotton fiber from Shanghai Mercury Home Textiles Co., Ltd. The long-staple cotton fiber used is type 133B fiber from Xinjiang Nongfa Industry Co., Ltd. The fluffy cotton fiber used is type 225C2 fiber from Shangqiu Jiuzhou Textile.
[0032] Test Method 1: Place the washable cotton quilt into a Siemens washing machine, select the cotton fabric washing program, wash at 40℃ for 1 hour, and after 5 washes, test according to the test standard GB / T8628.
[0033] The test results are as follows:
[0034]
[0035]
[0036] Test Method 2: The washable cotton quilt was sent to Guangzhou Inspection, Testing and Certification Group Co., Ltd., where it was independently tested for washing. The test results showed that the washed sample exhibited no damage, clumping, delamination, or exposure of the substrate. The test results are as follows:
[0037]
[0038] Regarding the shell
[0039] The cotton quilting and the quilt cover are sewn together using a zoned quilting technique. The zoning is mainly achieved by adjusting the quilting density and pattern.
[0040] In the zoned quilting process, the quilting density should ensure that the size of the outer pattern on the quilt cover does not exceed 35*35cm, while the size of the inner pattern is approximately (35-50)*(35-50)cm. Different pattern shapes are selected for the outer and inner sides based on the desired appearance. By adopting the above technical solution, the cotton quilt's ability to withstand external forces during washing is reduced.
[0041] Preferred Option 1: The quilting of the outer area is in the shape of small diamond grids, with each small diamond grid 5 having a side length of 30cm. The quilting of the inner area is in the shape of large diamond grids, with each large diamond grid 4 having a side length of 60cm. For example... Figure 2 As shown in the image, this solution allows cotton quilts to be directly placed in the washing machine for multiple washes, preventing the cotton filling from clumping, shifting, or tearing during washing. It also ensures the quilt maintains a smooth shape and provides a high level of comfort. Furthermore, it effectively solves the problem of cotton filling clumping and breaking during machine washing due to the high centrifugal force on the outer area, thus improving its washability.
[0042] Preferred Option 2: The quilting of the outer area consists of a combination of small circles and open circles. The small circle 51 has a diameter of 5cm, and the open circle 511 has a diameter of 20cm. The quilting of the inner area is in the shape of four rounded corners, with the size of the four rounded corners 41 being 50*40cm (the distance between the top and bottom corners × the distance between the left and right corners). For example... Figure 3 As shown in the image. This solution allows cotton quilts to be machine washed in various modes, such as gentle wash and warm wash. In addition, in gentle mode, it can be washed up to 20 times (after each wash and drying, it is washed again). After washing, the quilt has a smooth appearance, and when disassembled, the cotton filling does not clump or break, improving the quilt's washability.
[0043] Preferably, the duvet cover is made of 100% cotton and / or 100% polyester fabric. The duvet cover features a three-sided piping design, with the piping protruding 1cm to form a complete cotton duvet. The duvet cover also features a 3-7cm wide edging and corner bracing design to form a complete cotton duvet. The duvet filling edges can also have a 3-7cm wide edging, or use a four-sided piping technique or other four-sided internal fixing methods. These technical solutions ensure that the four corners of the cotton duvet are protected during washing.
[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
