Description

Technical Field

[0001] The utility model relates to the technical field of home textile product production, in particular to a quilt cover made of a home textile functional fabric with a quickly changeable specification. Background Art

[0002] With the improvement of people's living standards, home textile products made of new functional fabrics such as graphene, tencel, modal, and bamboo fiber are increasingly favored by consumers due to their superior performance. In actual production, due to the softness, thinness, and weft skewing of functional fabrics, the fabric processing is difficult and the quality requirements are high. Moreover, the specifications of the quilt covers made of functional fabrics are fixed sizes. When the newly purchased quilt cover does not match the size of the original old quilt core at home, it will cause non-matching in use and a poor experience. Especially when swapping beddings, whether changing from a large bed to a small bed or from a small bed to a large bed, embarrassing situations will occur due to the non-matching sizes of the quilt cover and the quilt core. Therefore, it is particularly important to research a new type of home textile functional fabric quilt cover that can adapt to different quilt core sizes. Summary of the Invention

[0003] To overcome the deficiencies of the prior art, the invention purpose of the utility model is to provide a quilt cover made of a home textile functional fabric with a quickly changeable specification, so as to overcome the problem of inconvenient processing caused by soft, thin, and weft-skewed fabrics and meet the assembly requirements of different specifications of quilt cores.

[0004] The quilt cover with a quickly changeable specification of the utility model includes a quilt cover surface and a quilt cover lining. The left, right, and head sides of the quilt cover surface and the quilt cover lining are sewn and connected, and one side of the feet of the quilt cover surface and the quilt cover lining is connected by a quilt foot closed-end zipper.

[0005] The quilt cover surface includes a left small piece of the quilt surface, a middle piece of the quilt surface, and a right small piece of the quilt surface, which are sewn and connected in sequence from left to right; the quilt cover lining includes a left small piece of the quilt lining, a middle piece of the quilt lining, and a right small piece of the quilt lining, which are sewn and connected in sequence from left to right.

[0006] The right side of the left small piece of the quilt surface and the left small piece of the quilt lining is also connected by an invisible open-end zipper, and the left side of the right small piece of the quilt surface and the right small piece of the quilt lining is also connected by another invisible open-end zipper. By opening or closing one or two of the invisible open-end zippers, the width specification of the quilt cover can be quickly changed.

[0007] Furthermore, there is an invisible zipper distance from the side part between the invisible open-end zipper and the side of the quilt cover.

[0008] Further, there are duvet inner binding straps for fixing the duvet core at both side edges of the duvet inner and at the connection of the invisible open-end zipper, and the duvet inner binding straps are evenly distributed along both side edges of the duvet inner and at the connection of the invisible open-end zipper.

[0009] Further, there is a duvet foot closed-end zipper decorative stitch for concealing the duvet foot closed-end zipper at the duvet foot closed-end zipper.

[0010] Further, the width of the finished duvet cover with quickly changeable specifications can be changed between 1.6 meters, 1.9 meters, and 2.2 meters. The widths of the left small piece of the duvet face, the right small piece of the duvet face, the left small piece of the duvet lining, and the right small piece of the duvet lining are 0.3 meters, and the widths of the middle piece of the duvet face and the middle piece of the duvet lining are 1.6 meters.

[0011] Further, the home textile functional fabric is a pure-spun or blended fabric made of graphene, tencel, modal, and bamboo fiber.

[0012] Further, the duvet foot closed-end zipper is a 3# closed-end nylon zipper.

[0013] Compared with the prior art, the present utility model can achieve high-quality, efficient, and stable mass production through the coordinated cooperation of processes such as cutting, sewing, and steam ironing. It better controls the influence of the soft, thin, and draping characteristics of the fiber fabric on the product quality, and effectively realizes that the duvet cover made of the functional fabric can be changed in size and specifications. When in use, fold the 30-cm side small pieces on both left and right sides into the duvet cover, thread and zip up the open end of the invisible open-end zipper. If only zip up the invisible open-end zipper on one side, the width of the duvet cover is 1.9 meters, which can be used for a double bed with a width of 1.5 meters; if zip up the invisible open-end zippers on both sides, the width of the duvet cover is 1.6 meters, which can be used for a single bed with a width of 1.2 meters; if both invisible zippers on both sides are opened, the width of the duvet cover is 2.2 meters, which can be used for a large bed with a width of 1.8 meters, so as to achieve the purpose of quickly changing the width specification of the duvet cover, making it better match duvet cores of different sizes and specifications, and maintaining the breathability, comfort, and softness of the product. Using the invisible open-end zipper maintains the aesthetic appearance of the product, solves the quality bottleneck in production, realizes the function of multi-purpose use of one duvet, and has the characteristics of low cost, comfort, durability, variable size, and beauty.
