4. DESCRIPTION:

Technical Field of the Invention

[0001] The present invention generally relates to a method of identifying yarn with different amount of cationic content percentages. More particularly the present invention relates to a method for a direct visual identification of yarn with different cationic strengths.

Background of the Invention

[0002] There are different processes used to prepare yarn for subsequent textile treatments and for changing the characteristics of the yarn for a particular end use. It is often desirable in textile yarn handling and weaving operations to be able to readily identify particular yarns. For example, when a beam of yarns for weaving are made up of multiple different yarns including different sizes or fiber types or cationic contents, applying distinguishing coloration to the composite yarns allows the beam to be readily inspected and further allows yarn "piece up" to be quickly accomplished in the event of a particular yarn breakage during weaving. This coloration must be easily removable, so that it does not interfere with permanent dyeing.

[0003] Typically, a fabric manufacturer receives different types of yarn from a yarn producer. The yarn has different dye abilities, tenacities or other properties. Conventionally, the type of yarn is indicated on each package of yarn received from the yarn producer, but when the yarn is removed from the package, it is often impossible for the fabric manufacturer to distinguish it from other types of yarn.

[0004] Additionally, a common way of manufacturing patterned textile fabrics such as carpeting is through the use of yarns or fibers of various colors. Melt or solution dyed yarns are easily distinguishable in the fabric manufacturing process as their built-in colors are visible to a process operator. The temporary coloration to the fibers and yarn is typically accomplished by spraying temporary washable dyes or the basic dyes carried in a liquid transfer medium such as water during the fiber mixing stage to treated fibers or to the un-treated fibers or to the blend of treated and un-treated fibers. For yarns, it is achieved by the way of temporary dyeing of the cationic yarn in a package dyeing machine. These basic dyes have very low affinity to the cellulose fibers.

[0005] In the light of aforementioned discussion, there exists a need for a method for readily identifying different percentage cationic strengths of yarn by performing a tinting process and to eliminate confusion or error in aligning a cationic yarn at the time of sectional warping or knitting or weaving.
