Benefits of technology

The invention seeks to address the problem of adding extra materials to a tube core to maintain its strength. The solution proposed involves adding a minimal amount of paper layers that offer a moisture barrier, resulting in a cost-effective tube core that maintains its strength over time and exposure to humidity. The method also includes minimizing the weight of paper while still ensuring the tube core's strength.

Problems solved by technology

However, the addition of paper to the tube core increases the cost of the tube core.

Embodiment Construction

[0034]The term “cores” or “tube cores” are used herein interchangeably and are intended to include all such articles which may be used for textile winding, whether they define a tube, cone or other shape. They may be used with a variety of materials such as threads, filaments, fibers, yam, etc., and of whatever composition such as spandex, nylon including nylon bulk continuous filament, silk, cotton, jute, linen, wool, rayon, etc.

[0035]The tube cores of one aspect include a surface layer, at least one moisture barrier layer that is an interior moisture barrier and two or more layers of paper. Typically, the surface layer will also include a moisture barrier and several layers of paper are included.

[0036]The cores are prepared on any of a variety of well-known devices to prepare wound paper tubes. Typically, this includes preparing strips of the paper (also commonly referred to as paper board or card board), combined with the interior moisture barrier layer. The surface layer which m...

Abstract

The invention relates to tube cores for yarn, especially elastomeric yarn such as spandex. The tube cores include a moisture barrier, which provides an increase in strength for a tube core including the same amount of paper or a maintenance of strength for a tube core including a reduced amount of paper.

Description

FIELD OF THE INVENTION[0001]The present invention is directed to a tube core including a moisture barrier, which maintains the integrity of the tube core over time and / or after exposure to humidity. A method for preparing a tube core that meets these goals while minimizing the weight of paper included in the tube core is also provided.BACKGROUND OF RELATED TECHNOLOGY[0002]Textiles yarns can be wound onto cores to provide a yarn package after yarns are prepared. This permits ease of storage, shipping, and subsequent use of the yarns. Typically, the core is exposed to the force of the yarn which is under tension during the winding process. If the core lacks sufficient strength, it may collapse under the pressure exerted by the yarn, resulting in failure of the core and making the yarn package unusable for its intended purpose. Other factors that contribute to potential core failure are the types of yarn (elastic yarns can provide a greater force) and exposure to moisture / humidity.SUMM...
