摘要:
An applicator for use in applying chemical treatments to textile fibers is described which does not require the presence of a reservoir of the chemical treatment in close proximity to where the textile fibers are treated. The applicator has a rotating cylindrical roll which rotates continuously during application and is in rotatable horizontal attachment with a support means. The rotating cylindrical roll contacts the filaments at one portion one roll while at another portion on the roll a delivery means having a slot and cavity to which there is provided the chemical treatment is in fluid contact with the rotating applicator roll. The chemical treatment flows from the cavity through the slot and onto the rotating applicator roll to contact the textile filaments at another location on the roll. The chemical treatment is supplied to the cavity of the delivery means by a fluid control means which provides a continuous and controlled amount of the chemical treatment to the delivery means. In this manner, the precise amount of chemical treatment needed to treat the textile filaments can be applied to the cylindrical applicator roll to prevent waste of any chemical treatment. The applicator can also have a housing which surrounds the rotatable applicator roll and delivery means and provides an opening for fluid attachment between the delivery means and the fluid flow control means and also provides an opening through which a longitudinal portion of the rotatable applicating means can protrude to contact the textile filaments outside the housing. Also, in lieu of a housing, the applicator may simply have a collecting device located underneath the rotatable applicating roll and delivery means to catch any discarded chemical treatment.
摘要:
Apparatus and method for coloring yarn continuously in sheets thereof, the apparatus including a spatial sequence apparatus for testing the yarn by pre-stressing; a yarn tension relaxing means; a printing apparatus for coloring the yarn in an accurately predetermined longitudinal pattern; control means for correcting wet yarn length increase as the yarn progresses through the printer; wet hot box for fixation of the dye stuff onto the yarn fiber; yarn washing means; combined apparatus for yarn drying and/or stress relieving by raising the yarn temperature; yarn relative lateral displacement means; yarn longitudinal displacement means; and finally a tufting machine or a take up means such as a beam. The method steps include sequentially testing the yarn for weakness, coloring the yarn while relaxed, fixation of the dye stuff on the yarn, washing the yarn, drying and/or setting the yarn, laterally and longitudinally realigning the yarns of the sheet to obtain individual yarn positions eventually resulting in a desired pattern, and finally leading the yarn directly to a tufting machine or winding the yarn on beams or other packages which will later feed into a tufting machine. In the description, the word "printing" is used synonymously with the word "coloring."

摘要:
Aqueous treating media are applied onto running webs via a restrictor gap in a hollow body extending over the whole width of the web. A springy strip of material, which regulates and homogenizes the throughput, is clamped, under the force from a spring, between the components defining the gap.
摘要:
A process for the surface treatment of a running substrate by an electrical discharge created between two roller electrodes, comprising a first roller electrode and a second roller electrode, in a gas mixture comprising the steps of passing the substrate in between the two roller electrodes by applying it against the first roller electrode; injecting the gas mixture between the rollers to apply a first surface treatment to the substrate; passing the substrate in between the two roller electrodes by applying it against a second roller electrode; and injecting the gas mixture between the rollers to apply a second surface treatment to the substrate.
