摘要:
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.

An apparatus and method are described for treating one or more yarn strands before or after the strand is dyed. The apparatus preferably includes a modified space dyeing apparatus having a dye applicator modified to be used as a treatment composition applicator for treating a yarn strand. The apparatus enables a high speed yarn dyeing and treatment method. Also described is a method and composition for treating yarn with a polyphenolic derivative composition to form a bleach-resistant yarn.
摘要:
In apparatus for continuously treating a thread, for example a textile thread, including squeezing and/or drying a humid thread wherein the humid thread is passed into a zone traversed by a current of air at a pressure lower than that prevailing about the thread during the operation that provoked its humidification, the zone comprises a chamber having an inlet and an outlet between which there is a helical conduit.
摘要:
An apparatus for dyeing a textile substrate using a plurality of applicators that each apply an increment of a total dye application. In one form a reduced indigo dye in a leuco-state is applied in an inert atmosphere substantially isolated from oxidizing substances. In another form the foamed dye is applied while open to the atmosphere. In both forms holddown rollers or inverted applicators are located between applicators at decreasing depths to minimize increases in tension as the substrate travels over successive applicator faces.

摘要:
A process is provided for space dyeing synthetic yarn in which the synthetic yarn, such as polyester yarn, wound upon a yarn package, is first treated by immersing the ends of the package into a solution of at least one sublimatable ink, thereby dyeing the yarn located at the ends of the package but leaving the yarn at the center of the package undyed, and then at least two ends from at least two such packages are passed through otherwise conventional drawing and texturizing apparatus. Each yarn so fed is intermittently dyed and undyed along its length, the color strength near the dye boundaries being attenuated and muted due to sublimation of the inks and diffusion and migration of the dyes through the yarn ends and into the package. By utilizing at least two feed yarn packages in such process having significantly different diameters and different colored ends thereof, very highly random dyeing effects are achieved in a knitted or woven fabric produced from such yarns. Also provided are the new, space-dyed yarns produced by the aforesaid process and fabrics produced from such yarns.

The invention provides a partial dyed yarn having a partial dyeing applied to a side surface of fibrous raw material and further provides a method for manufacturing thereof. A partial dyed yarn is provided by a dye liquid adhering method and a dye liquid adhering, drying and taking-up device which is capable of accomplishing a high quality dye printing yarn. A continuous fibrous raw material is passed through the dye liquid adhering roll, the dye liquid is partially or continuously adhered to the thread-like side surface of the fibrous raw material, and thereafter it is applied with a heat treatment to cause the yarn to be dyed in a desired color tone efficiently and quickly. The fibrous raw material is passed over a guiding groove formed at an outer circumference of the dye liquid adhering roll at a desired yarn speed while a tension force is being applied to it, the dye liquid adhering roll is properly rotated with its frictional force and at the same time, its amount of adhesion is controlled and the yarn is passed in a hot air drying device while it is turned therein so as to dry the adhered dye liquid. The yarn is then taken up as a dried cone and it is processed with heat treatment to obtain a yarn partially dyed on the side surface thereof.

This invention relates to a process for squeezing and/or drying a humid thread, particularly a textile thread, in the course of a treatment, such as dyeing, effected continuously on said thread during the rectilinear displacement thereof, wherein the humid thread is passed into a zone traversed by a current of air at a pressure much lower than the pressure prevailing about the thread during the operation having provoked its humidification. The invention also relates to an apparatus for continuously treating a thread, for example a textile thread, applying the process as described hereinabove.
