Problems solved by technology

Attempts to eliminate undyed areas by providing a constant spray of dye would result in the use of more dye than the present invention, with the result that in addition to the necessity of adjusting the dye formulation to compensate for the color imparted by overspray, a higher yield per pound of yarn would result. high cost
This approach also tends to exacerbate the problem of undesired overlapping of adjacent dyed areas and the overall result is neither predictable nor controllable in spaced color yarns

Embodiment Construction

[0023] The invention includes, but is not necessarily limited to, embodiments having one or more of the following features. The numbering used for elements in one figure is consistent throughout the figures. See attached picture, figure 1 A typical spacer staining region of the present invention is schematically represented. Since there are actually more yarns to be dyed than a single yarn to be dyed simultaneously, the present invention is designed with a creel 101 holding a plurality of yarn packages 103 fixed thereto.

[0024] Individual yarns ("yarn ends") (yarn end) from each yarn package 103 are unwound and passed through a first carding element 107 which causes each yarn end 105 to be spaced in an evenly spaced, parallel manner. The pattern is placed in place so that the yarns do not overlap and are properly spaced to form a yarn sheet 109 . The yarn sheet enters the dye application section 111 in the dyeing range, which will be described below. After dyeing, the ya...

Abstract

This invention relates to a space dyed yarn (119).

Description

technical field [0001] The present invention generally relates to a method and apparatus for continuous interval dyeing of yarn. More particularly, the present invention relates to a method and apparatus for spraying dye or other pattern-forming liquid onto a moving sheet of yarn, wherein the yarn sheet drive rollers cooperate with the applicator heads so that Registration provides the application of several different liquids, thereby providing the ability to apply their liquids to a moving sheet of yarn without unintentional untreated or overlapping portions, and wherein dye passing through the sheet of yarn is collected and are therefore recycled. Background technique [0002] A yarn product that has dyeing at different intervals along the length of the yarn is referred to as "interval dyed". Space dyed yarns are desirable because the yarns can be very easily formed into a woven fabric with an inherently random or pseudo-random pattern imparted by the shaped yarns that m...
