Abstract

Circular-knit, elastic, single-knit jersey fabric (10), of spun and/or continuous filament hard yarns (14) with bare spandex (12) plated in every course, has a cover factor in the range of 1.3 to 1.9, a basis weight from 140 to 240 g/m2, an elongation of 60% or more and low shrinkage. The circular knot, single-knit jersey fabric is produced by maintaining the draft of the spandex at or below 2X (100% elongation) and maintaining the finishing and drying temperature(s) below the spandex heat set temperature. The knit fabric meets the end-use specifications without heat setting.

Claims (13)

1. A method for making a circular knit, single jersey fabric (62) in which bare spandex yarn (12) from 17 to 33 dtex is plated with one or more spun or continuous filament hard yarns (14), or blends thereof, with yarn count from 35 to 85, and in which the spandex and hard yarn(s) are plated in every knit course to produce the circular knit, single jersey fabric (62) with a cover factor of from 1.3 to 1.9, wherein the improvement comprises:
controlling the draft on the spandex feed so that the spandex yarn is drafted no more than 100 % elongation of its original length when knit to form the circular knit, single jersey fabric (62); and finishing and drying (70) the knit fabric while maintaining the fabric at a temperature below such temperature required to heat set the spandex.
2. The method of claim 1, wherein the knit fabric (62) is maintained at temperatures below 160°C during finishing and drying (70).
3. The method of claim 1, wherein the knit fabric (62) has a length in the warp direction and is dried (70) or compacted (72) while subject to an overfeed in its length.
4. The method of claim 1, wherein the knit fabric (82) has a spandex content of from 3.5% to 14% by weight based on the total fabric weight per square meter.
5. The method of claim 4, wherein the knit fabric (52)has a spandex content of from 5% to 10% by weight based on the total fabric weight per square meter.
6. The method of claim 1, wherein the cover factor of the knit fabric (62) is 1.4.
7. The method of claim 1, wherein finishing comprises one or more steps selected from the group consisting of: cleaning (64), bleaching (64), dyeing (64), drying (70), and compacting (72) and any combination of such steps.
8. The method of claim 1, wherein the hard yarn (14) is selected from the group consisting of spun cotton and cotton blended with synthetic fiber or yarn.
9. A circular knit, elastic, single knit jersey fabric (62) made by a method for making a circular knit, single jersey fabric (62) in which bare spandex yarn (12) from 17 to 33 dtex is plated with one or more spun or continuous filament hard yarns (14), or blends thereof, with yarn count from 35 to 85, and in which the spandex and hard yarn(s) are plated in every knit course to produce the circular knit, single jersey fabric (62) with a cover factor of from 1.3 to 1.9, wherein the improvement comprises:
controlling the draft an the spandex feed so that the spandex yarn is drafted no more than 100 % elongation of its original length when knit to form the circular knit, single jersey fabric (62); and finishing and drying (70) the knit fabric while maintaining the fabric at a temperature below such temperature required to heat set the spandex.
10. The circular knit, elastic, single knit jersey fabric (62) of claim 9, wherein the hard yarn (14) is cotton or a cotton blend, and the fabric, made at a temperature below such temperature required to heat set the spandex, has a basis weight of from 140 to 240 g/m2.
11. The circular knit, elastic, single knit jersey fabric (62) of claim 9, wherein the fabric, made at a temperature below such temperature required to heat set the spandex, has an elongation of at least 60% in its length (warp) direction.
12. The circular knit, elastic, single knit jersey fabric (62) of Claim 9, wherein the fabric at a temperature below such temperature required to heat set the spandex resulting in a fabric having a shrinkage of 7% or less after washing.
13. A garment made from the circular knit, elastic, single knit jersey fabric (62), made at a temperature below such temperature required to heat set the spandex, of claim 9.
