The present invention relates to top covers for use on a bed mattress made up with linens such as in place of a bed spread.
Typical bed spreads are placed over a bed mattress that has been made up with linen sheets, such as one-ply fitted and flat sheets. But bed spreads, particularly styles that are filled and/or quilted, are much heavier and bulkier than the typical thin, light linen sheets they are placed over. As a result, when a person gets into the made-up bed, if the bed spread is still over the linen sheets, the person might be uncomfortable. Also, in the hospitality field, such as for hotels and motels, the heavy bed spreads represent costs in handling and laundering that are higher than the costs associated with handling and laundering of the linen sheets. To reduce these concerns, many in the hospitality industry have begun to use top covers in place of bed spreads over the made-up bed mattress. Current top covers, while still thicker and heavier than linen sheets, are lighter and thinner than the bed spreads they replace. They are thus less uncomfortable to someone in the bed and have reduced handling and laundering cost as compared to bed spreads. But they still require additional processing beyond just washing, such as ironing and pressing. Those additional processing steps add costs as well.
The present invention provides a top cover that avoids the need for additional processing, such as ironing and pressing, to serve as a top cover for use on a bed mattress made up with linen sheets. To that end, and in accordance with the principles of the present invention, the top cover is a woven web comprising warp yarns and fill yarns, where at least the fill yarns or the warp yarns of the woven web include a first plurality of non-spandex, non-core spun elastomeric yarns and a second plurality of non-elastomeric yarns. The elastomeric yarns will shrink or crinkle more when laundered than will the non-elastomeric yarns to provide a wash activated patterning to the woven web. Advantageously, the wash activated patterning is provided after the first laundering. As a result, the sheeting-like woven web will have a permanent and irreversible textured/wrinkled pattern. The wash activated patterning thus provides a bulky look or texture sufficient to provide the look and feel of a top cover, without the bulk of a bed spread, while providing a functional and attractive decorative element to the bed make-up absent any need for ironing or pressing. The construction of the top cover has the further advantage that it is lighter than either bed spreads or current top covers so as to have the lightness and advantages of a linen sheet.
The fabric web is advantageously plain woven in an approximately 4 oz. per square yard fabric. The amount of non-elastomeric yarns to elastomeric yarns in the warp or in the fill may be in a ratio that is advantageously a multiple of 4:1, such as 4:1 or 12:3, although other ratios could be selected. Further, the insertion pattern of the elastomeric and non-elastomeric yarns may be alternating as respective clusters of the non-elastomeric yarn and of the non-spandex, non-core spun elastomeric yarn. The fabric web is cut into a generally rectangular configuration, and hemmed, in dimensions suitable for use as a top cover over a bed mattress made up with linen sheets. The fabric web (in the greige state before being made up into the top cover) or the top cover after it is made, but before being delivered to a customer, may be laundered to obtain the wash activated patterning.
Where the fill yarns are the elastomeric and non-elastomeric yarns, the warp yarns may be any typical yarns, such as cellulose-containing, synthetic, or a combination thereof, which may be cotton, cotton/poly, or polyester, an advantageous example of which is 50% cotton/50% poly spun yarn. Where the warp yarns are the elastomeric and non-elastomeric yarns, the fill yarns may be the typical yarns, such as cellulose-containing, synthetic, or a combination thereof. Or the warp and fill yarns might each be the elastomeric and non-elastomeric yarns. The elastomeric and non-elastomeric yarns are advantageously a combination of 100% polyester multifilaments yarns. In that regard, the non-elastomeric yarns may be synthetic filament yarns, such as PET polyester, although other yarns could be used provided they have less shrink as compared to the elastomeric yarns. The non-spandex, non-core spun elastomeric yarns may be a bi-component polyester textile fiber which may include PTT and PET polyester, such as elasterell-p.
By virtue of the foregoing there is thus provided a top cover that avoids the need for additional processing, such as ironing and pressing, to serve as a top cover for use on a bed mattress made up with linen sheets. These and other advantages of the present invention shall be made apparent from the accompanying drawings and the description thereof.
The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate an embodiment of the invention and together with the general description of the invention given above and the detailed description of the embodiment given below, serve to explain the principles of the present invention.
With reference to the
In one embodiment, the fill yarns 16 are a combination of 100% polyester multifilament yarns, a first plurality thereof 16′ as previously described being the non-spandex, non-core spun elastomeric yarns, and a second plurality 16″ being non-elastomeric synthetic filament yarns. While the yarns 16′ may be any non-spandex, non-core spun elastomeric synthetic, they may be a bi-component polyester textile fiber, such as 150 denier elasterell-p, which is a combination of PET and PTT polyester. The yarns 16″ may be any non-elastomeric synthetic filament yarn, but one advantageous yarn is 150 denier PET polyester. In that embodiment, the warp yarns may be selected from the group consisting of cotton, cotton/poly, and polyester, and may advantageously be 50% cotton/50% poly spun yarn.
Woven web 12 is advantageously plain woven in an approximately 4 oz. per square yard. And the amount of yarns 16″ to yarns 16′ may be in a ratio that is advantageously a multiple of 4:1, such as 4:1 or 12:3, although other ratios could be selected. Further, the insertion pattern of the yarns 16 may be alternating as a cluster C1 of the non-elastomeric yarns 16″ and a cluster C2 of the non-spandex, non-core spun elastomeric yarns 16′. While only one cluster C1 and two clusters C2 are shown in
With further reference to
The woven web 12 is cut and formed into a rectangular configuration and hemmed to form a top hem 20, bottom hem 21, left side hem 22, and right side hem 23 along the respective edges thereof as seen in
A method of forming the top cover 10 includes weaving and/or obtaining the woven web 12; cutting or otherwise forming it into a rectangular configuration slightly larger than the desired dimension so as to be of a size near that desired to go over the made-up bed mattress 30; folding over excess portions along each edge; and hemming the folded over portions to form the hem 20, 21, 22, and 23 as a top cover 10 of a dimension suitable for use as a top cover over the made-up bed mattress 30 (
The woven web 12 may be laundered prior to forming the top cover 10, such as in the greige state (before forming into a rectangular configuration), in order to provide a wash activated patterning, or it may be laundered after being formed into the top cover 10 for that purpose.
In use, and with reference to
By virtue of the foregoing there is thus provided a top cover 10 that avoids the need for additional processing, such as ironing and pressing, to serve as a top cover for use on a bed mattress made up with linen sheets is lighter and thinner than either bed spreads or current top covers to thus provide the advantages of linen sheets, while still able to serve as a top cover for use on a bed mattress made up with linen sheets.
While the present invention has been illustrated by a description of a particular embodiment thereof, and while the embodiment has been described in some detail, it is not intended to restrict or in any way limit the scope of the appended claims to such detail. Additional advantages and modifications will readily appear to those skilled in the art. By way of example, while the embodiment is described with reference to the elastomeric yarns 16′ and non-elastomeric yarns 16″ comprising the fill yarns 16, alternatively or additionally, the warp yarns 14 could be comprised of such elastomeric and non-elastomeric yarns. Additionally, while fill yarns 16″ are advantageously non-elastomeric synthetic filament yarns, they could be natural yarns, or a blend of natural and synthetic yarns, provided they have less shrink as compared to the elastomeric yarns 16′ to thus provide a wash activated patterning. The invention in its broader aspects is therefore not limited to the specific details, representative apparatus and method shown and described. Accordingly, departures may be made from such details without departing from the scope or spirit of the general inventive concept.
