IRONING BOARD PAD
Abstract
An ironing board pad is provided having a cover portion, shaped
and sized to cover the upper surface of an ironing board, and a
skirt portion to attach the pad to an ironing board. The cover
portion comprises an underlying resilient supporting layer, a
portion of which is covered by layers to provide a good ironing
surface and a portion of which is covered by layers to permit a hot
iron to stand thereon for extended periods without a trivet. The
layers of the ironing surface comprise an outermost stretchable
knit material and an intermediate resilient flexible foam, the knit
material being made of a blend of yarns, plated so that a
heat-resistant yarn is predominant on its outer surface and a yarn
of lesser heat resistance is predominant on its inner surface.

Description
SUMMARY OF THE INVENTION
This invention relates to an ironing board pad having a combination
of desirable features.
The pad comprises a cover portion, sized and shaped to at least
partially cover the upper surface of an ironing board, and a skirt
portion attached to the periphery of the cover portion and
containing means, such as a drawstring, to attach the pad to the
ironing board.
The cover portion of the ironing board pad consists of several
layers including an underlying resilient supporting layer which
comes into direct contact with the upper surface of the ironing
board when the pad is in use. The resilient supporting layer is
preferably a needle punched non-woven nylon material having a
thickness from about one-eighth to about three-eighths inches.
Overlying the resilient supporting layer over most of the length of
the ironing board, there is an outermost layer comprising a
stretchable knit material and an intermediate layer comprising a
resilient flexible foam.
The outermost knit layer contains two different yarns, one of which
is a heat-resistant yarn, and the knit pattern of the material is a
plated pattern, such that the heat-resistant yarn predominates on
the outer surface of the material and the other yarn, which has
lesser heat resistance, predominates on its inner surface. The
preferred heat-resistant yarn is a yarn of heat resistant nylon,
such as the nylon sold under the trademark Nomex. The preferred
yarn of lesser heat resistance is a cotton yarn.
The intermediate flexible foam layer is preferably a layer of
flexible polyether polyurethane foam and is preferably laminated to
the flexible knit material as by flame lamination.
The head end of the ironing board pad has a small area designed as
an iron rest in addition to being useful for ironing operations. In
this area, the resilient support layer is covered by an outermost
layer of woven fabric made of a heat-resistant yarn and an
intermediate layer of heavy flannel made of heat-resistant nylon.
The combined thickness of the woven fabric and the flannel in this
portion of the ironing board pad is substantially equal to the
combined thickness of the stretchable knit material and the
flexible foam layer in the remainder of the pad so that the upper
surface of the pad is relatively level.
DETAILED DESCRIPTION OF THE INVENTION
The invention may be better understood by reference to the drawings
in which:
FIG. 1 is a top perspective of the ironing board pad of the
invention, partially broken away to reveal underlying layers;
FIG. 2 is a bottom perspective of the ironing board pad;
FIG. 3 is a fragmentary sectional view along plane 3--3 of FIG. 1,
somewhat exaggerated for clarity of illustration;
FIG. 4 is a fragmentary sectional view along plane 4--4 of FIG. 1,
somewhat exaggerated for clarity of illustration; and
FIG. 5 is a fragmentary sectional view along plane 5--5 of FIG. 1,
somewhat exaggerated for clarity of illustration.
As shown in the figures, the ironing board pad of this invention
comprises an outer skirt portion 11 and an inner cover portion 12
designed to cover the upper surface of an ironing board.
Skirt portion 11 extends around cover portion 12; and hem 13,
containing drawstring 14, extends around the outer edge of the
skirt. When the ironing board pad is put over an ironing board,
drawing and tying drawstring 14 holds it securely in place.
Resilient layer 16 is the underlying layer throughout the cover
portion area. It is a needle punched non-woven nylon having a
weight of about 28 oz. per square yard and a thickness of about
one-fourth inch.
The major portion of the upper surface of the cover portion
comprises double stretch knit material 17 made of cotton yarn and
high temperature-resistant nylon yarn and plated so that the nylon
yarn predominates on the outer surface which comes into direct
contact with the hot sole plate of an iron during the ironing
operation.
Flexible, resilient polyurethane foam 18 is made from a polyester
polyol. It is flame laminated to knit material 17 so that they
stretch and recover as a unit under iron pressure during the
ironing operation. The coaction of the stretch knit material and
the flexible resilient foam, particularly when laminated to each
other, provides an important advantage in that these materials,
together, provide the proper combination of resilience and
stiffness so that garment accessories, such as, buttons and
zippers, are absorbed into the pad during ironing and leave no
marks on the garment being pressed. If a woven material were used
in place of stretch knit material 17, this effect would not be
achieved.
The remainder of the upper surface of the cover portion, a small
area at the head end of the pad, comprises woven fabric 19 made of
temperature-resistant nylon. Fabric 19 is stitched to the knit
material-polyurethane laminate by stitching 21, as shown in FIG.
5.
Flannel layer 22, made of temperature-resistant nylon, is between
fabric 19 and resilient layer 16. It is about three-sixteenths inch
in thickness and weighs approximately 14 oz. per square yard.
Fabric 19 and flannel layer 22 together provide heat resistance to
a substantial depth, so that a hot iron may stand indefinitely on
fabric 19 without damage to the pad and without scorching, or
otherwise damaging fabric 19.
Stitching 23 around the entire periphery of cover portion 12 and
through resilient layer 16 and its overlying layers holds the skirt
portion to the cover portion of the pad.
An important feature of this invention is in the use of a stretch
knit material which is plated to have a preponderance of high
temperature-resistant yarn on its outer surface which is in direct
contact with the hot sole plate of an iron. Where the
temperature-resistant yarn is a high-priced yarn, such as
temperature-resistant nylon, the use of a plated knit permits
lowered cost by reserving the high-priced yarn only for the
location which requires it. In any case, the combination in the
stretch knit material of a temperature-resistant yarn with another
yarn of lower temperature resistance makes available to the
material some of the properties of the latter yarn which may be
desirable. Cotton, for example, has better water absorption than
nylon and improves the water absorption capacity of the knit
material. This property is useful for maintaining sufficient
wetness in the cover fabric to provide a steaming effect through
the fabric being ironed.
The invention has been described with respect to a specific
embodiment thereof, but modifications thereof may be employed
without departing from the invention, as will be understood by
those skilled in the art.
