Description

High-strength and 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

With the increase of living standard, swimming starts to rise slowly as a healthy exercise. As swimming places, indoor swimming pools and outdoor swimming pools are classified. Compared with an indoor swimming pool, the outdoor swimming pool has the advantages of fresh air and wide visual field. However, outdoor swimming pools, which are exposed directly to the sun, tend to evaporate water faster than indoor swimming pools, resulting in greater waste. In order to overcome the disadvantage of faster water evaporation in outdoor swimming pools, a layer of swimming pool cover cloth is generally covered on the water surface of the outdoor swimming pool.

The existing swimming pool cover cloth usually adopts a sealed plane structure made of polypropylene, and the surface of the swimming pool cover cloth is not provided with a breathable structure and is waterproof so as to prevent sundries and dirty water from entering the swimming pool. However, the accumulated impurities and dirty water tend to form a concave on the surface of the pool cover, and the concave on the surface of the pool cover gradually deepens with the increase of the accumulated matters.

In response to the above problems, the bottom of the pool cover material is often fitted with a filter outlet to allow only clean water to flow into the pool. However, if the distance between the water outlet and the depression on the surface of the pool cover is too long, water accumulation still occurs, so that the overall strength of the pool cover is affected due to the arrangement of a plurality of water outlets.

Further, the interwoven yarns are warp and weft yarns woven vertically.

Furthermore, adjacent cutting grooves in the width direction of the yarns are arranged at intervals and partially overlapped, and the yarns are arranged at intervals along the cutting grooves distributed in the axial direction so as to form connecting parts among the cutting grooves.

Further, adjacent connecting portions in the yarn width direction and uncut portions of the yarn body form linear stretching portions which form a net-like stretched yarn structure in cooperation with the adjacent connecting portions after sufficient stretching.

Furthermore, the swimming pool cover is subjected to hot rolling treatment after being woven.

Further, the yarns are plastic spinnable materials having the necessary strength and flexibility.

Furthermore, the yarns are made of polypropylene plastic materials, and are flat fiber base materials after being extruded through melt spinning.

Further, the warp density is 30-40 yarns per inch, with the size of the yarns in this direction being in the range of 1000-2000 denier.

Further, the density in the fill direction is 10-20 yarns per inch, and the size of the yarns in this direction is in the range of 500-700 denier.

Furthermore, the weight of the knitted fabric per square gram is 160-330 g.

The invention has the following beneficial effects: the whole swimming pool cover is of a net structure, so that the whole strength is high, the weight is lighter, and water accumulation on the surface can be effectively avoided; the mesh structures formed by the flat yarns and the yarns are overlapped and overlapped, so that good filtering and shading effects are achieved.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

Referring to fig. 1-4, a high-strength high-shading-rate swimming pool cover comprises interwoven yarns, in this example, warp yarns 1 and weft yarns 2 which are basically vertically woven, the warp yarns 1 and the weft yarns 2 are flat synthetic fiber yarns, a plurality of cutting grooves 3 which are arranged at intervals are arranged in the yarns in at least one direction along the axial direction, in this embodiment, notches are arranged on the weft yarns 2 to form a discontinuous strip-shaped slotted hole structure 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 weaving structure to ensure the filtering performance and the 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 yarn is arranged at intervals along the axially distributed cutting grooves 3 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 being sufficiently stretched, cooperate with the connecting portions 4 to form a net-like stretched yarn structure as shown by the broken line in fig. 4. The length and the interval of the cutting grooves 3 can be selected according to actual requirements on the premise of ensuring the compactness and the strength of the yarn.

In addition, the above-mentioned knitted material is subjected to a hot calendering treatment, for example by means of the rolls of a calender, at a temperature and pressure chosen so that the material melts and recrystallizes rapidly. In this way, in the recrystallization process, the material (part of the linear stretching part 5) around the cut groove in the yarn is flattened to be partially overlapped and bonded after crystallization, so as to form a more compact pore, and meanwhile, the strength of the yarn and the strength of the interwoven yarn are improved.
