Woven pool cover fabric providing water drainage and at least 95% shade

Abstract

A woven pool cover fabric comprises a thermoplastic warp yarn and a thermoplastic fibrillated weft filling yarn, providing at least 95% shade. A woven swimming pool cover having polyolefin warp yarns and fibrillated polyolefin weft yarns is lightweight, water permeable, and provides at least % shade, thus preventing algae growth and debris accumulation in the pool, as well as facilitating ease of installation and removal of the cover.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] None BACKGROUND OF THE INVENTION [0002] Broadly, this invention relates to swimming pool covers. More specifically, this invention relates to seasonal-use pool covers which prevent the accumulation of debris in the pool, yet allow water to pass through freely. [0003] There are generally two major classifications of swimming pool covers. One is a seasonal cover intended to protect the pool from the elements during a season or seasons of non-use, typically winter, but possibly including parts of spring or autumn. Such a cover is typically referred to as a winter cover. The other is a daily-use cover, often used during the pool season (i.e., summer), which may act as a solar heater and / or thermal blanket. [0004] It is commonplace for swimming pool owners to install a cover over their swimming pool to protect the pool from leaves and other debris which would otherwise accumulate in the pool when it is not in use, for example over the winter...

Benefits of technology

[0016] It is therefore, an object of the present invention to provide a woven pool cover fabric comprising a thermoplastic warp yarn and a thermoplastic fibrillated tape filling yarn providing at least 95% shade.

[0017] It is another object of the present invention to provide a woven pool cover fabric that is air and water permeable and which reduces growth of algae in water containing pools.

[0019] In general the present invention provides a woven pool cover fabric comprising a thermoplastic warp yarn and a thermoplastic fibrillated weft filling yarn, providing at least 95% shade.

Problems solved by technology

However, during the off-season, light from the sun shining either directly on the pool water, or through the winter cover, causes algae to grow in the pool water.

Such removal is both time consuming and expensive since the pool must again be chemically treated and physically cleaned to kill and remove the algae and render the pool water safe for humans.

While such covers provide a physical barrier to the deposition of debris in the pool, they can be relatively heavy, as much as 12 to 14 ounces per square yard.

Such weight can make them difficult to manipulate and store.

If not, heating the remaining pool water in a covered pool can lead to the formation and multiplication of various algae.

Conversely, for a seasonal-use cover, accumulated water can present a challenge to removing the cover at the beginning of the pool-season.

While attempts have been made heretofore to produce a lightweight pool cover, the art has not provided a lightweight pool cover that prevents the growth of algae, prevents debris entry to the pool, yet does not allow water accumulation thereupon.
