Description

High-strength high-shading-rate swimming pool cover

Technical Field

The invention relates to the technical field of flexible covering materials, in particular to a high-strength high-shading-rate swimming pool cover.

Background

Swimming as a healthy sport starts to slowly rise with the increase of living standard. As a place for swimming, there are an indoor swimming pool and an outdoor swimming pool. Compared with an indoor swimming pool, the outdoor swimming pool has the advantages of fresh air and wide visual field. However, outdoor swimming pools tend to evaporate faster than indoor swimming pools because of direct exposure to the sun, resulting in greater waste. In order to overcome the defect of faster evaporation of water in the outdoor swimming pool, a layer of swimming pool cover cloth is generally covered on the water surface of the outdoor swimming pool.

The conventional swimming pool cover cloth often adopts a sealed plane structure made of polypropylene, and the surface of the conventional swimming pool cover cloth is not provided with a ventilation structure and is watertight so as to prevent sundries and dirty water from entering the swimming pool. However, as a result, accumulated debris and dirty water tend to form individual depressions in the pool cover surface, and as the accumulation increases, the depressions in the pool cover surface also gradually deepen.

In response to the above problems, the bottom of the pool cover material is often fitted with a drain port with a filtering function to allow only clean water to flow into the pool. However, if the distance between the water outlet and the recess on the surface of the swimming pool cover is too long, water accumulation can still occur, so that a plurality of water outlets are generally arranged, and the overall strength of the swimming pool cover can be influenced.

Detailed Description

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments.

Examples of the embodiments are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements throughout or elements having like or similar functionality. The embodiments described below by referring to the drawings are illustrative and intended to explain the present invention and should not be construed as limiting the invention.

Referring to fig. 1-4, a swimming pool cover with high strength and high shading rate comprises interweaved yarns, wherein the warp yarns 1 and the weft yarns 2 are basically vertically woven in the example, the warp yarns 1 and the weft yarns 2 are flat synthetic fiber yarns, a plurality of cutting grooves 3 are formed in the yarns in at least one direction along the axial direction at intervals, notches are formed in the weft yarns 2 in the embodiment to form discontinuous strip-shaped slotted hole structures in the yarns, and a reticular stretching structure can be formed after bearing, so that the water permeability of the yarns is increased, and meanwhile, the yarns are woven to form a relatively compact reticular woven structure so as to ensure the filtering performance and shading performance.

Specifically, as shown in fig. 3 and 4, adjacent cutting grooves 3 in the yarn width direction are arranged at intervals and partially overlapped, and the cutting grooves 3 are distributed along the axial direction of the yarn at intervals so as to form connecting parts 4 between the cutting grooves 3; as shown in fig. 5, the adjacent connecting portions 4 in the yarn width direction and the uncut portions of the yarn body form linear stretching portions 5 which, after sufficient stretching, cooperate with the connecting portions 4 to form a net-like stretching wire structure as the broken line portion in fig. 4. The length and the interval of the cutting grooves 3 can be selected on the premise of ensuring the compactness and the strength of the yarns according to actual requirements.

In addition, the woven material is subjected to a hot-casting process, such as by passing through rolls of a calender, at a temperature and pressure selected so that the material melts and can be rapidly recrystallized. In this way, during the recrystallization process, the material (part of the linear stretching part 5) around the cutting groove in the yarn is flattened to generate partial overlapping and bonded after crystallization, so that more compact pores are formed, and meanwhile, the strength of the yarn itself and the strength after interweaving among the yarns are improved.

Warp yarn 1 and weft yarn 2 are polypropylene plastic materials, and are flat fiber substrates after melt spinning extrusion. Of course, other plastic spinnable materials having the necessary strength and flexibility are also possible.
