Benefits of technology

The present invention is an apparatus and method for dyeing textile yarns in a foam condition. The apparatus includes driven infeed and outwardly spaced guide rollers, which divide the yarn sheet into separate portions. A pair of yarn sheet recombining nip rollers recombines the separated yarn sheet portions into a single sheet. A foam applicator applies foanged dye to the inner and outer surfaces of the yarns in the recombined sheet. The apparatus and method allow for the use of different dyes or foam applicators for different yarns, resulting in different color variations and fashion options. The invention is particularly useful for denim fabric production.

Problems solved by technology

A problem with the prior art apparatuses and methods is that the mass of yarns in the traveling sheet are crowded together and tend to overlap or otherwise become entangled with adjacent yarns, which makes it difficult, if not impossible, to coat the entire surface of each yarn without leaving undyed streaks as a result of the limited amount of dye applied during the first application.

Embodiment Construction

[0017]The dyeing apparatus 10 of the preferred embodiment of the present invention illustrated in the accompanying drawings, feeds originally undyed cotton yarns that are wound on warp beams 12 supported in two racks, 14 and 16, arranged in series with each rack supporting four warp beams 18 and 20 in a two over two stacking arrangement. One rack 14 is outboard of the other rack 16. Yarns from the four beams 18 of the outboard rack 14 are withdrawn and combined into a single yarn sheet 22 that passes under the beams 20 of the inboard rack 16 and combined with the yarns drawn from the beams 20 of the inner rack 16 to form a combined single sheet 24 drawn from the eight warp beams.

[0018]In threading up the apparatus 10, a cross yarn 26 is laid across the top of the sheet 22 of yarns from the outboard rack 14 prior to the sheet passing under the beams 20 of the inner rack 16. In this manner, the yarns from the inner rack 16 are laid on top of the cross yarn 26 in combining with the yar...

Abstract

Dyeing a traveling sheet of textile yarn with a dye in foamed condition, and, more particularly, dyeing by separating a traveling sheet of yarn into separate spaced portions and applying foamed dye to the inner facing and outer facing surfaces of the yarns in the spaced portions. Then recombining the spaced portions into a single sheet and further applying foamed dye to the yarn in the recombined sheet.

Description

FIELD OF THE INVENTION[0001]Dyeing a traveling sheet of textile yarn with dye in foam condition, and more particularly, dyeing by separating a traveling inner sheet of yarn into separate spaced portions and applying foam and dye to the inner facing and outer facing surfaces of the yarns in the spaced portions, then recombining the spaced portions into a single sheet and further applying foam guide to the yarns in the recombined sheet.BACKGROUND OF THE INVENTION[0002]It is known to use foamed dye to dye textile substrates by applying multiple coats of dye in a foamed state sequentially on traveling textile substrates using spaced foam applicators on opposite sides of the traveling substrates. One such prior art apparatus and method developed by the assignee of the present invention has a vertical series of spaced pairs of opposed foam applicators that apply foam to opposite sides of a traveling cotton textile substrate. In the specific embodiment of the prior art illustrated in the a...
