Abstract
Description
Technical Field
[0001] This utility model relates to the field of bedding technology, specifically to a fitted sheet. Background Technology
[0002] Fitted sheets are a highly practical bedding item. They not only protect the mattress and extend its lifespan, but also provide a better sleep experience and an aesthetically pleasing bedding effect. For example... Figure 1 As shown, conventional fitted sheets mostly use a single layer of fabric or a quilted design. Single-layer fitted sheets are thin and breathable, lacking a cushioning layer and failing to improve comfort. Although secured with elastic bands, they easily shift during use, and the conventional knitted fabric tends to loosen and fail to maintain a smooth, fitted surface. Conventional quilted mattresses typically employ a three-layer structure: a quilted surface followed by elastic bands or a fitted sheet. This offers a slight improvement over standard fitted sheets, but the multi-stitched seams create natural unevenness, resulting in less flatness and comfort. The middle layer of cotton adds thickness, increases folding volume, takes up more space for washing, and prolongs drying time, also affecting overall breathability. Therefore, improvements to existing technology are necessary. Utility Model Content

[0020] To make the technical means, inventive features, objectives and effects of the utility model easy to understand, the present utility model is further described below in conjunction with specific embodiments.
[0021] like Figure 2 and Figure 3As shown, an embodiment of this utility model discloses a fitted sheet for use on a mattress, comprising a fitted sheet and a surrounding fitted sheet structure. The fitted sheet structure includes a pair of long-side fitted sheets and a pair of short-side fitted sheets corresponding to the mattress. The fitted sheet and the fitted sheet structure are joined together. In this embodiment, the upper edges of the fitted sheet and the fitted sheet structure can be joined by four-thread overlock stitching. The fitted sheet is made of knitted elastic air-layer fabric, which is soft and comfortable to the touch, has good breathability, and can increase air circulation during sleep. Its porous multi-layered woven structure can effectively expel sweat, keeping the body dry, comfortable, and not stuffy, and can also increase the fluffiness and thickness of the fabric. The long-side fitted sheets include two layers of knitted fabric 21 and an elastic mesh fabric 22 disposed between the two layers of knitted fabric 21, which facilitates better fit to the mattress. The width and length of the elastic mesh fabric 22 are equal to the dimensions of the two layers of knitted fabric 21. The short-side fitted sheets 3 are made of woven fabric. The long-side fitted sheets and the short-side fitted sheets are joined by concealed stitching.
[0022] The joint between the bed surface 1 and the surrounding bed frame structure is located on the side of the mattress, meaning the size of the bed surface 1 is larger than the size of the mattress surface. The seam 4 between the long side bed frame 2 and the short side bed frame 3 is on the long side of the mattress, preventing slippage during use. The specific position of the seam 4 on the long side of the mattress is determined according to usage needs, as long as it achieves the purpose of fixation. Furthermore, the bottom edges of the long side bed frame 2 and the short side bed frame 3 are sewn together with a double-needle overlock sewing machine.
[0023] Specifically, the seam between the mattress surface 1 and the surrounding frame structure is located on the side of the mattress, 3-5cm from the edge of the mattress surface. This is designed to prevent the body from touching the seam during use, making it more comfortable and ensuring that the overall fitted sheet has a more uniform and conforming elasticity. The position of the seam can also be set according to the actual mattress height and usage needs.
[0024] In addition, the elastic mesh fabric 22 of the long side bed rail 2 is fixed to the two layers of knitted fabric 21 by triangular pins. To improve the efficiency of cutting, the two layers of knitted fabric 21 can be made by folding a single piece of knitted fabric in half. The short side bed rail 3 is also a double-layer structure and can be made by folding a single layer of woven fabric in half.
[0025] In practical use, and then combined with Figures 2 to 4 As shown, the fitted sheet in this embodiment is used on mattresses of a certain size (such as 150cm*200cm, 180cm*200cm, etc., with a thickness of 15cm to 30cm). First, according to the finished product size, process requirements, and the splicing position of the mattress surround, the outer fabric pattern is designed. Based on the design drawing, a cut pattern is made (such as...). Figure 4(As shown), cut suitable bed sheet 1 and bed surround fabric. Mark the stitching positions of the bed surround fabric on the cut fabric according to the pattern. Then, fold a piece of knitted fabric in half to form two layers of knitted fabric 21 according to the pattern. Add elastic mesh fabric 22 between the two layers of knitted fabric 21 and fix it with triangular needles to form the long side bed surround 2. Then fold a layer of woven fabric in half to form a double-layer short side bed surround 3. When sewing, gather four darts on the four corners of the bed sheet 1 according to the pattern. First, overlock the two sides of the four darts at an angle, and then sew them together. Pay attention to the elasticity of the fabric and the smoothness of the sewing. Then, stitch the short side bed surround 3 and the long side bed surround 2 together with a blind stitch. Sew the bottom edge of the bed surround with a wide double needle on a coverstitch machine. Finally, sew the bed sheet 1 and bed surround structure together. Overlock the bed surround with four threads according to the stitching positions marked on the cut. Then sew it with a wide double needle on a coverstitch machine to complete the splicing process of the fitted sheet.
[0026] In summary, this utility model provides a fitted sheet with a simple structure and convenient assembly / disassembly. The bed surface 1 is made of knitted elastic air-layer fabric, while the bed surround is made of a combination of knitted elastic fabric and woven fabric. Through adjustments to the size and splicing process, the fitted sheet is installed smoothly and snugly, and the bed surface 1 has a certain air cushion layer, which can increase the comfort of use. In addition, this fitted sheet does not use elastic bands; it utilizes the elasticity of the bed surround to fit the mattress or Simmons mattress smoothly, achieving easy assembly and easy storage. It has high practical value.
