SAME
Abstract
A method for manufacturing anti-interference hybrid fabric
prepares multiple fiber strands made of a compound material. The
fiber strands have multiple strands of conductive fiber and
multiple strands of non-conductive fiber serving as filament yarns
for weaving the anti-interference hybrid fabric. The method further
inputs the fiber strands serving respectively as warp yarns and
filling yarns to a loom machine to weave a finished product of the
anti-interference hybrid fabric after selecting at least one
unblocking area on the finished product. The warp and filling yarns
passing through the at least one unblocking area correspond to the
strands of non-conductive fiber and the rest of warp and filling
yarns correspond to the strands of conductive fiber. Accordingly, a
cover formed by the finished product has the at least one
unblocking area allowing a communication product having the cover
to transmit or receive electromagnetic signals therethrough.

Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to woven fabric and a method
for manufacturing the same and more particularly to
anti-interference hybrid fabric and a method for manufacturing the
same.
[0003] 2. Description of the Related Art
[0004] To pursue value-added features to have light weight, thin
profile, high strength and the like, electronic products, such as
mobile phones, employ compound material, such as carbon fiber, to
build covers thereof, thereby reducing the weight and thickness of
the mobile phones and raising the quality and value of the
electronic products.
[0005] As carbon fiber is conductive, covers formed by carbon fiber
fabric in a hardening process are also conductive. When
electromagnetic signals of mobile phone pass through those
conductive covers, the signals are blocked or interfered with. The
received signals are weak and thus require higher signal strength
to pass through the covers. Such covers certainly cause operational
inconvenience to users of the mobile phones.
SUMMARY OF THE INVENTION
[0006] A first objective of the present invention is to provide
anti-interference hybrid fabric having at least one unblocking area
woven by non-conductive fiber and allowing electromagnetic signals
to pass therethrough.
[0007] To achieve the foregoing objective, the anti-interference
hybrid fabric has at least one unblocking area, multiple
longitudinal strands of fiber and multiple transverse strands of
fiber.
[0008] The at least one unblocking area is formed on the
anti-interference hybrid fabric.
[0009] A part of the longitudinal strands of fiber are conductive
and the rest of the longitudinal strands of fiber are
non-conductive.
[0010] The transverse strands of fiber are interwoven with the
longitudinal strands of fiber. A part of the transverse strands of
fiber are conductive. The rest of the transverse strands of fiber
are non-conductive. The part of the non-conductive longitudinal
strands of fiber and the non-conductive transverse strands of fiber
are woven to form the at least one unblocking area. The part of the
conductive longitudinal strands of fiber and the conductive
transverse strands of fiber are woven to form the rest of
anti-interference hybrid fabric.
[0011] A second objective of the present invention is to provide a
method for manufacturing anti-interference hybrid fabric having
unblocking area woven by non-conductive fiber and allowing
electromagnetic signals to pass therethrough.
[0012] To achieve the foregoing objective, the method for
manufacturing anti-interference hybrid fabric has a filament yarn
preparing step, a fabric weaving step and a finished product
outputting step.
[0013] The filament yarn preparing step prepares multiple fiber
strands made of a compound material. The fiber strands have
multiple strands of conductive fiber and multiple strands of
non-conductive fiber, and the strands of conductive fiber and the
strands of non-conductive fiber serve as filament yarns for weaving
the anti-interference hybrid fabric.
[0014] The fabric weaving step inputs the fiber strands serving
respectively as warp yarns and filling yarns to a loom machine to
weave a finished product of the anti-interference hybrid fabric
after selecting at least one unblocking area on the finished
product. The warp yarns passing through the at least one unblocking
area correspond to a part of the strands of non-conductive fiber
and the rest of warp yarns correspond to a part of the strands of
conductive fiber. The filling yarns passing through the at least
one non-blocking area correspond to the remaining strands of
non-conductive fiber and the rest of filling yarns correspond to
the remaining strands of conductive fiber.
[0015] The finished product outputting step continuously outputs
the finished product of the anti-interference hybrid fabric. The
finished product of the anti-interference hybrid fabric has the at
least one unblocking area woven by the warp yarns and the filling
yarns corresponding to the strands of non-conductive fiber and the
remaining area woven by the warp yarns and the filling yarns
corresponding to the strands of conductive fiber.
[0016] A finished product manufactured by the method of the present
invention is cut to a suitable size and is pressed together with
resin to form a cover of a mobile phone or a communication
product.
[0017] The benefits of the anti-interference hybrid fabric and the
method for manufacturing anti-interference hybrid fabric lies in
that the finished product of the anti-interference hybrid fabric
has at least one unblocking area. As the unblocking area has only
strands of non-conductive fiber passing therethrough, the at least
one unblocking area of the cover made by the finished product of
the anti-interference hybrid fabric is non-conductive, thereby
avoiding interfering with electromagnetic signals transmitted or
received by the mobile phone or communication product. Accordingly,
besides having high strength, tough wear-resistance and light
weight, the cover made from the hybrid fabric and resin for a
mobile phone or a communication product can also avoid
communication interference to the mobile phone or the communication
product.
[0018] Other objectives, advantages and novel features of the
invention will become more apparent from the following detailed
description when taken in conjunction with the accompanying
drawings.

DETAILED DESCRIPTION OF THE INVENTION
[0025] With reference to FIG. 1, a method for manufacturing
anti-interference hybrid fabric in accordance with the present
invention has the following steps.
[0026] Filament Yarn Preparing Step:
[0027] Multiple fiber strands made of a compound material are
prepared. The fiber strands have multiple strands of conductive
fiber and multiple strands of non-conductive fiber. The strands of
conductive fiber and the non-conductive fiber serve as the filament
yarns for weaving fabric. The conductive fiber 11 may be carbon
fiber or metal fiber. The non-conductive fiber 12 may be chemical
fibers including organic fibers and inorganic fibers having high
strength and high ductility, such as polyethylene terephthalate
(PET) fibers, polyester (PE) fibers, polypropylene (PP) fibers,
Kevlar fibers, aramid fibers, para aramid fibers, glass fibers and
basalt fibers.
[0028] Fabric Weaving Step:
[0029] The fiber strands having multiple strands of conductive
fiber and multiple strands of non-conductive fiber are used
respectively as warp yarns and filling yarns for weaving fabric.
Before the weaving starts, at least one unblocking area on the
woven fabric outputted from a loom machine is selected to satisfy
signal transceiving requirements of a communication product, such
as a mobile phone on which the woven fabric is mounted. Each one of
the at least one unblocking area is woven by multiple warp yarns
and multiple filling yarns respectively having multiple strands of
non-conductive fiber. Given the at least one unblocking area, after
the finished product is outputted from a loom machine and is cut
and, together with resin, is pressed to make a cover, the at least
one unblocking area can be located on at least one corresponding
location of a communication product through which the communication
product transceives communication signals to prevent from blocking
the communication signals.
[0030] The fabric weaving step starts after the at least one
non-blocking area is selected. Upon weaving, the warp yarns passing
through the at least one non-blocking area pertain to the fiber
strands of non-conductive fiber while the rest of warp yarns
pertain to the fiber strands of conductive fiber. Likewise, the
filling yarns passing through the at least one non-blocking area
pertain to the fiber strands of non-conductive fiber while the rest
of filling yarns pertain to the fiber strands of conductive
fiber.
[0031] Finished Product Outputting Step:
[0032] With reference to FIGS. 2 and 3, through the fabric weaving
step, the loom machine continuously outputs a finished product of
anti-interference hybrid fabric 10 containing conductive fiber 11
and non-conductive fiber 12. The finished product of
anti-interference hybrid fabric 10 has at least one unblocking area
13 woven by the warp yarns and the filling yarns containing the
non-conductive fiber 12.
[0033] With reference to FIGS. 4 to 6, when employed, the finished
product of anti-interference hybrid fabric 10 is cut to a size
suitable for a cover 20 of a mobile phone and is pressed together
with resin to form the cover 20. As having only strands of
non-conductive fiber 12 passing through, the at least one
unblocking area 13 of the cover 20 is non-conductive and thus
prevents the mobile phone from being interfered with or blocks
electromagnetic signals transmitted or received by the mobile
phone. Besides having high strength, tough wear-resistance and
light weight, the cover made from the hybrid fabric 10 and resin
for a mobile phone or a communication product can also avoid
communication interference to the mobile phone or communication
product.
[0034] Even though numerous characteristics and advantages of the
present invention have been set forth in the foregoing description,
together with details of the structure and function of the
invention, the disclosure is illustrative only. Changes may be made
in detail, especially in matters of shape, size, and arrangement of
parts within the principles of the invention to the full extent
indicated by the broad general meaning of the terms in which the
appended claims are expressed.
