Abstract
A new apparatus is disclosed for the rope-drying of dyed fabric resulting in a new fabric pattern having distinctive patterning. The process has three critical areas, particularly: the apparatus' ability to maintain a tension on the rope while it is being dried over contact dryers; the rope being formed into a very defined cylinder through an elongated tube; and the length of contact drying being sufficient to impart the migration of the dye stuff through the rope to form the applicable pattern.
Claims9
An apparatus for migration-dyeing of fabrics which comprises a means for applying dye on an open sheet of fabric so that the fabric can attain a pick-up of from about 55 weight percent up to about 75 weight percent;
- a means for converting the sheet into a tight fabric rope wherein an integral part of said means is a tube-eye;
- placing tension on the tight fabric rope;
- a contact drying means for the tight fabric rope to pass over so that the rope intimately contacts the hot surface of the dryer under such tension that the tight rope fabric is flattened against the drying surface, forcing all layers into intimate contact.
A process for migration-dyeing which comprises applying dye to a fabric in open sheet form, forming the dye containing fabric into a tight tubular rope form by use of a tube-eye, then the tight rope fabric is passed through a contact dryer at temperatures equal to a fixing temperature of the dye used under tension so that the rope is flattened from a tubular rope form into a flat rope form wherein each layer within the rope is in intimate contact with the layers on either side and the flat rope is in intimate contact with the contact dryers surface;
- the contact time on the contact dryers surface will vary from about 5 minutes to about 60 minutes.
