DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
This invention relates to a material transmitting sunlight, especially for bathing wear or light-protective clothing, consisting of a net-like, knitted fabric with mesh openings which is printed with contrasting bright colors and cannot therefore be seen through when put on the skin.
Such a material as well as bathing wear made therefrom are already known. Such a bathing suit or bikini has the advantage that even the parts of the body clad therewith tan in the sun, even although they are covered as with conventional bathing wear and are not visible. This bathing wear therefore facilitates tanning substantially free from demarcations in sunny weather, without the need for nude bathing or seeking out a bathing beach provided therefor or suitable country.
The known bathing wear involves a printed net-like knitted fabric of cotton. This is really only suitable for pure sun bathing and not for swimming. If this bathing wear gets wet its opacity is no longer fully guaranteed. The wet bathing wear also dries comparatively badly, which reduces the wearing comfort or requires a change of clothes. Moreover the adaptability to the body and the fit depending thereon leave something to be desired, especially after many wearings or long life.
SUMMARY OF THE INVENTION
The invention is accordingly based on the object of so improving the material initially described that the clothing produced therefrom combines optimum tanning properties and a cladding action which is not reduced by wetness with enhanced hang and wearing comfort.
This object is met according to the invention in the knitted fabric consists of polyamide fibres and a polyurethane elastomer and has a honeycomb-like structure with rows of mesh openings which extend in at least three angularly offset directions.
The material according to the invention is very elastic and able to stretch because of the components of the knitted fabric and its honeycomb structure, moreover in at least three and even four directions. This leads to an enhanced ability to adapt to the shape of the body, whereby the polygonal (hexagonal) mesh openings correspondingly widen out when being worn, so that the sun's rays and thus the UV rays leading to tanning of the skin can penetrate well. At the same time, the knitted fabric lying against the body remains opaque because of the printing with contrasting bright colours, moreover even when the knitted fabric is wet. Furthermore the wet material dries particularly rapidly, for which not only the fibres employed but also the loose structure of the appropriately light knitted fabric are responsible. Accordingly, appropriate bathing wear is suitable for both sun bathing and swimming.
The knitted fabric can be composed of 60% to 80% polyamide fibers and 20% to 40% polyurethane elastomer, preferably of 73% polyamide fiber and 27% polyurethane elastomer. The knitted fabric can have a mass per unit area of 120-200 g/m.sup.2, preferably 160 g/m.sup.2. The mesh openings can have a clear mesh opening with amounting to 0.2-1.0 mm, preferably 0.5 mm.
Investigations with a knitted fabric having hexagonal mesh openings of uniform size of 73% nylon and 27% polyurethane in thread counts of 40 denier and 280 denier respectively with a mass per unit area of 160 g/m.sup.2 have shown that the knitted fabric allows through about 65% of the UV rays of the sun or in other words shields the body from about 1/3 of the UV radiation. This corresponds approximately to the use of a sun cream with a light-protection factor of 10 on the bare skin. Thus the material according to the invention is not only specially suitable for bathing wear but is also of general advantage when the skin is to be protected from over-strong sun radiation without the use of sun creams, which are made on a fat or oil basis, while a tanning effects is definitely desired. Numerous different kinds of articles of clothing offer themselves as such light-protective clothing, for example T-shirts, leggings, cycling trousers and Capri trousers. It is conceivable that pr
