Description

Technical Field

[0001] This utility model relates to the field of bedding, specifically to a fitted sheet. Background Technology

[0002] Currently, fitted sheets are mostly used as accessories for duvet covers, etc. Their fabric varieties are relatively limited, their comfort level is not high, and their functionality is not strong enough.

[0003] For example, conventional fitted sheet fabrics are single-layer knitted or woven fabrics, which have the following disadvantages: they are prone to shrinkage, often shrinking by 5%–8% or even more after washing, resulting in poor coverage and curling edges; they are prone to deformation, with poor fabric dimensional stability, easily deforming and loosening during use; they are not comfortable, lacking softness and a delicate feel; they are relatively thin, and in contact with the mattress, the thin fabric cannot provide sufficient cushioning, affecting comfort; and they wrinkle easily: the uneven surface wrinkles easily, affecting appearance.

[0004] Furthermore, fitted sheets often suffer from unevenness, wrinkles, and shifting after installation. To address this, existing technologies incorporate elastic bands to reinforce the connection between the fitted sheet and the mattress. However, the presence of these additional components makes folding and storage difficult.

[0005] In summary, there is an urgent need to develop a fitted sheet that combines softness and support with a certain degree of moisture absorption and skin-friendliness to meet the comfort requirements of the home textile industry, especially fitted sheet products, and to address the drawback of the difficulty in folding and storing due to the presence of additional components.

The scope of protection of the present invention shall be determined by the claims. Detailed Implementation

[0051] To better illustrate this utility model and facilitate understanding of its technical solution, typical but non-limiting embodiments of this utility model are as follows:

[0052] Fitted sheets are increasingly popular due to their convenience, speed, and ease of care. However, the fabric options for the fitted sheet are limited, resulting in insufficient comfort and functionality, which affects comfort. Furthermore, the uneven surface makes them prone to wrinkling, affecting aesthetics. Additionally, fitted sheets need to be secured to the mattress to prevent shifting during use. Current methods to address this shifting issue typically use elastic bands or other supports, but these can hinder folding and storage. Therefore, this invention optimizes the fitted sheet's surface and edging to achieve superior performance. The fitted sheet is comfortable, breathable, smooth, wrinkle-resistant, soft, and provides good coverage and a certain thickness, combining aesthetics and comfort. The edging prevents slipping and shifting, while maintaining a smooth, even finish. It also folds easily for convenient storage. Details are as follows:
