Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The invention relates to a curtain, and more particularly to
a curtain fabric material.
[0003] 2. Description of the Related Art
[0004] Various types of curtains have been provided in the art
according to different applications. Commonly seen curtains include
pleated curtains, venetian curtains, roll curtain, roman curtains,
etc. Due to different requirements of the curtains, several light
blocking materials have been used to make the curtains, such as,
plastic and wooden slats for venetian curtains, and woven fabrics
made of cotton and plastic yarns for pleated curtains, roll
curtains, roman curtains, etc.
[0005] Woven fabric curtains can be readily provided with
decorative patterns by weaving or printing. However, because woven
fabric curtains are generally porous, they are susceptible of light
leakage, which results in insufficient light blocking effect.
SUMMARY OF THE INVENTION
[0006] An object of the present invention is to provide a curtain
fabric material with an improved light-blocking effect.
[0007] Accordingly, the present invention provides a curtain fabric
material which comprises two fabric layers, an intermediate film
sandwiched between the fabric layers, and at least one non-light
transmissive layer formed on at least one surface of the
intermediate film.
BRIEF DESCRIPTION OF THE DRAWINGS
[0008] Other features and advantages of the present invention will
become apparent in the following detailed description of the
preferred embodiment with reference to the accompanying drawings,
of which:
[0009] FIG. 1 is an exploded view showing a curtain fabric material
according to a preferred embodiment of the present invention;
[0010] FIG. 2 is a perspective view illustrating a pleated curtain
device incorporating the curtain fabric material of FIG. 1;
[0011] FIG. 3 is a fragmentary sectional view of the curtain fabric
material of FIG. 1.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0012] Referring to FIGS. 1, 2 and 3, there is shown a curtain
fabric material 1 according to a preferred embodiment of the
present invention usable for a pleated curtain device 2, which
includes a top frame 21, a bottom bar 22, and two pull ropes 23
that can be pulled using the bottom bar 22. The curtain fabric
material 1 is formed into a pleated structure and is connected to
the top frame 21 and the bottom bar 22. The pull ropes 23 pass
through the curtain fabric material 1. While the curtain fabric
material 1 is used in a pleated curtain device 2 in this
embodiment, according to another embodiment of the present
invention, the fabric material 1 may be used in other types of
curtains, such as, roll curtains, roman curtains, etc.
[0013] The curtain fabric material 1 includes two fabric layers 11,
an intermediate film 12 sandwiched between the fabric layers 11,
and a non-light transmissive layer 13 formed on at least one
surface 121 of the intermediate film 12. The fabric layers 11 may
be woven or nonwoven fabric layers. Patterns may be formed on the
woven fabric layers by weaving, knitting or printing. In this
embodiment, nonwoven fabric layers are used as the fabric layers
11.
[0014] The intermediate film 12 is a plastic film which may be made
from a suitable plastic material. In this embodiment polyethylene
terephatalate (PET) is used for the intermediate film 12. The
non-light transmissive layer 13 is a metal layer formed on one of
two surfaces 121 of the intermediate film 12. The metal layer may
be formed by electroplating using a suitable metal, such as, zinc,
or aluminum. While the intermediate film 12 has only one non-light
transmissive layer 13 on one of the surfaces 121 in this
embodiment, it may have two non-light transmissive layers 13 formed
respectively on both of the surfaces 121 thereof. Furthermore, any
suitable plastic material may be used for the intermediate film 12
as long as it can flex together with the fabric layers 11, and any
suitable material may be used for the non-light transmissive layer
13 as long as it has a light-blocking effect.
[0015] The curtain fabric material 1 may be fabricated by first
electroplating the intermediate film 12 to form the non-light
transmissive layer 13, followed by attaching the electroplated
intermediate film 12 to the fabric layers 11 such as by adhesive
bonding.
[0016] Because the curtain fabric material 1 of this invention
utilizes the fabric layers 11 and the flexible electroplated
intermediate film 12 that does not impair the flexibility of the
fabric layers 11 and that can effectively block light, the curtain
fabric material 1 not only has the characteristics of a fabric but
also is sufficient for blocking light. The non-light transmissive
layer 13 can provide a protection against electromagnetic radiation
in addition to the light-blocking effect.
[0017] While the present invention has been described in connection
with what is considered the most practical and preferred
embodiments, it is understood that this invention is not limited to
the disclosed embodiment but is intended to cover various
arrangements included within the spirit and scope of the broadest
interpretation so as to encompass all such modifications and
equivalent arrangements.
