WOVEN FABRIC FOR BED SHEETS

Abstract

In a woven fabric the warp threads are woven in a weaving pattern in a warp direction of two warp threads up and then one down, adjacent columns in the weaving pattern being offset such that there are no rows in which the weft thread is always up. The warp threads are between 80 s and 100 s and the weft threads are between 60 s and 120 s. There are between 144 to 220 warp threads per inch of fabric and from 60 to 400 weft threads per inch of fabric. This fabric is smooth and soft like satin and durable like percale.

Claims

1. A woven fabric comprised of warp threads and weft threads wherein: the warp threads are woven in a weaving pattern in a warp direction of two warp threads up and then one down adjacent columns in the weaving pattern being offset such that there are no rows in which the weft thread is always up; the warp threads being between 80 s and 100 s; and the weft threads being between 60 s and 120 s.

2. The woven fabric of claim 1 wherein the weave pattern also comprises a selvedge.

3. The woven fabric of claim 1 comprising from 144 to 220 warp threads per inch of fabric.

4. The woven fabric of claim 1 comprising from 60 to 400 weft threads per inch of fabric.

5. The woven fabric of claim 1 wherein the warp threads are cotton and the weft threads are cotton, polyester or rayon.

6. The woven fabric of claim 1 comprised of 80 s cotton warp threads and 80 s cotton weft threads.

Description

BRIEF DESCRIPTION OF THE DRAWING

[0009] FIG. 1 is an illustration of a weaving pattern known in the art in which the weft threads and the warp threads are identified.

[0010] FIG. 2 is a canvas representation of the weave pattern in FIG. 1.

[0011] FIG. 3 is a canvas representation of the weave pattern in the preferred embodiments of my woven fabric for bed sheets.

DESCRIPTION OF THE PRESENT PREFERRED EMBODIMENTS

[0012] Woven fabric is made by weaving weft threads through a series of warp threads such that at each intersection of a warp thread and a weft thread, the warp thread will be on the top surface of the fabric and the weft thread will be on the bottom surface of the fabric, called warp overlap, or the weft thread will be on the top surface of the fabric and the warp thread will be on the bottom surface of the fabric, called weft overlap. FIG. 1 shows a weaving pattern known in the art in which eight warp threads and seven weft threads are shown.

[0013] It is well known and quite common in the art to use a canvas, like a checkerboard, to illustrate a weaving pattern. Each square indicates an intersection of a weft thread and a warp thread. The presence of is an x or dot in the square indicates that warp thread is on the top surface of the fabric and the weft thread is on the bottom surface of the fabric, warp overlap. An empty square indicates that the weft thread is on the top surface of the fabric and the warp thread is on the bottom surface of the fabric, weft overlap. Interlacements occur where the warp thread and the weft thread change position, from being on the top surface to being on the bottom surface or vice versa. FIG. 2 is a canvas representation of the weave pattern shown in FIG. 1. Each of the warp threads are numbered in FIG. 2.

[0014] FIG. 3 shows the weaving pattern that is used in my woven fabric for bed sheets. In this weaving pattern warp threads 1 and 2 provide a selvedge. Then warp treads 3 through 8 are in the present preferred embodiment there are two warp threads up and then one down in the warp directions. In adjacent warp threads the pattern is offset such that there are no rows in which the weft thread is always up or always down.

[0015] Only fine threads are used in this woven fabric. The warp threads are between 80 s and 100 s. The weft threads are between 60 s and 120 s. There will be 144 to 220 warp threads per inch of fabric. The number of weft threads is 60 to 400 per inch.

[0016] By using fine weft threads and fine warp threads in the pattern shown in FIG. 3, I was able to achieve a durable woven fabric in which the bottom surface has a soft comfortable feel. This fabric does not have the pilling and lint formation problems of satin sheets.

[0017] A fabric made from 80 s cotton warp threads and 80 s cotton weft threads was made according to the fabric pattern shown in FIG. 3. Then this fabric was washed in a washing machine 5 times. After each washing the fabric was observed to see if any pilling had been formed. None was found after 5 washings. In contrast when a satin sheet was washed the same number of times, pilling formation occurred.

[0018] Although I prefer to make the fabric using cotton warp threads and cotton weft threads other types of thread could be used like polyester and rayon.

[0019] While I have described and illustrated certain pre sent preferred embodiments of woven fabric for bed sheets, the invention is not limited thereto but may be variously embodied within the scope of the following claims.
