Abstract
A top cover comprises a woven web of warp yarns and fill yarns, with a first plurality of the fill yarns (and/or the warp yarns) being non-spandex, non-core spun elastomeric yarns and a second plurality of the fill yarns (and/or the warp yarns) being non-elastomeric yarns whereby the top cover has a wash activated patterning so as to have a bulky look or texture after it is laundered, especially the first time it is laundered, which allows the top cover to serve as a top cover without the need for additional processing such as ironing or pressing.
Claims19
A top cover for use over a made-up bed mattress, the top cover comprising a woven web of warp yarns and fill yarns in a rectangular configuration and hems so as to be of a size to be used over a made-up bed mattress, the warp yarns or the fill yarns including a first cluster of a first plurality of non-spandex, non-core spun elastomeric yarns in a side-by-side arrangement and a second cluster of a second plurality of non-elastomeric yarns in a side-by-side arrangement, wherein the warp yarns or fill yarns comprise an alternating sequence of the first and second clusters, wherein the number of yarns in each second cluster is a multiple of the number of yarns in each first cluster, whereby the first clusters of non-spandex, non-core spun elastomeric yarns will shrink more when laundered than the second clusters of non-elastomeric yarns to provide a top cover having a wash activated patterning so as to have a bulky look or texture.
A method of forming a top cover comprising:
- obtaining a woven web of warp yarns and fill yarns with the warp yarns or the fill yarns including a first cluster of a first plurality of non-spandex, non-core spun elastomeric yarns and a second cluster of a second plurality of non-elastomeric yarns, wherein the warp yarns or the fill yarns comprise an alternating sequence of the first and second clusters;
- forming a rectangular configuration from the woven web of a size near that desired to go over a made-up bed mattress;
- hemming respective edges of the woven web;
- and
- laundering the woven web whereby to obtain a wash activated patterning defining a bulky look or texture.
A method of forming a top cover comprising:
- obtaining an already laundered woven web of warp yarns and fill yarns with the warp yarns or the fill yarns including a first cluster of a first plurality of non-spandex, non-core spun elastomeric yarns and a second cluster of a second plurality of non-elastomeric yarns, wherein the warp yarns or the fill yarns comprise an alternating sequence of the first and second clusters so as to have a wash activated patterning defining a bulky look or texture;
- forming a rectangular configuration from the woven web of a size near that desired to go over a made-up bed mattress;
- and
- hemming respective edges of the woven web.
A method of forming a top cover comprising:
- weaving warp and fill yarns into a woven web of warp yarns and fill yarns with the warp yarns or the fill yarns including a first cluster of a first plurality of non-spandex, non-core spun elastomeric yarns and a second cluster of a second plurality of non-elastomeric yarns, wherein the warp yarns or the fill yarns comprise an alternating sequence of the first and second clusters;
- forming a rectangular configuration from the woven web of a size near that desired to go over a made-up bed mattress;
- hemming respective edges of the woven web;
- and
- laundering the woven web whereby to obtain a wash activated patterning defining a bulky look or texture.
