"Procedure for handling packs" Priority s 15 »1-« 1969 - Great Britain

The "Invention .. refers to the treatment of packs and in particular to a process for the treatment of essentially ¹ borrowed cylindrical packs"

Textile materials are often deformed into packs ₉ in whatever form they are subjected to washing, dyeing or other treatment. A typical pack of this type is what is commonly referred to as "Oarnkäae"'o The treatment of such packs. , ■ gene with liquids, such as z-.bc, washing and dyeing, iwird currently usually performed ₉ characterized in that the fXtissigkeit is caused to flow through the pack in a substantially radial direction, usually from the center of the package to the outside. Desired® »if the flow can also sum

Center done «, Multiple packs are usually placed on one perforated hollow mandrel attached to produce a substantially cylindrical packing »so that the liquid passes through a number of individual packs circulates at the same time. Furthermore, woven fabrics are often turned into a mandrel on a mandrel The roll is wound and the liquid is caused to flow through the roll in a generally radial direction.

The conventional Radialflußbehandlungen make use of large volumes W treatment medium required Doho high liquid ratios, when a liquid is used, and produce large volumes of spent medium which must be eliminated. In addition, uniform coloring of the yarn or thread or complete elimination of soiling during washing is not always achieved in a completely satisfactory manner in such a process, at least in part due to a variation in the flow rate of the treatment liquid between the inside and outside of the yarn "

Furthermore have Radialflußverfahren, in which a gas is used as the treatment medium, such äoBo in the air drying of "cheese winding", the disadvantage that the medium through the top! Part of the "cheese roll" easily passes than through the lower part "in particular those ψ, As a result, the lower part takes longer to treat, and therefore it is difficult to achieve uniform treatment of the entire package 8u. Uneven flow of media through the paokung creates humidity changes and the problems of migration of materials within the pack.

It has now been found, surprisingly, that the volume of the treatments is sufficient for the treatment of a "Qarnkäses" or another essentially cylindrical

see permeable packing is required to be reduced can and that the uniformity of the treatment can be improved if one allows the medium to flow through the Packing in a substantially parallel to the longitudinal axis Direction prompted.

Thus, the invention proposes a method for the treatment of substantially cylindrical packages according to which is executed by the fact that a treatment medium through the packing in a substantially extending to its Iiängsachse direction through guide one to d

A number of individual units, for example "cheese rolls", can be treated simultaneously by gathering them together on a central mandrel, for example, to produce a substantially cylindrical package. The assembly (in the form of a cylinder) is then placed coaxially into a tube whose internal diameter is advantageously substantially equal to or only slightly greater than the outer diameter of the coil "Venn the inner diameter of the tube is substantially greater than the outer diameter of the coil, can then seal means, for example ringföraige Dichtungsringej be provided ■■ ϊ to to prevent the treatment medium from flowing past the packs. Alternatively, the tube can be made of a flexible material, for example plastic, so that it can be deformed to adapt to the pack Pack to be pulled · The Be Treatment medium is then pumped into one end of the tube and made to flow lengthways through the tube. Usually the medium percolates down through the vertical pipe, but if desired it can be pushed up through the pipe. However, the treatment tube need not be arranged vertically, / and in fact it can also be horizontal or inclined

It is more difficult to parallel a flow of a liquid. its axis _t but the flow is still essentially axial *

The temperature of the treatment medium depends to a certain extent on the treatment to be carried out and the yarn or thread to be treated. In particular, the temperature of the treatment medium should be below that at which damage to the material of which the packing is made can occur, although in some cases it may be desirable to use a hot medium. For example, when washing a hot liquid often advantageous "Normally, however, is not übersehreiten the medium temperature 10O ⁰ C.

The treatment medium can be any medium with which a treatment of the material of the packing is to be carried out » For example, it can be an aqueous liquid or an organic solvent such as ZoB. a washing liquid, a rinsing liquid, a finishing agent or a coloring liquid », or it can be a gaseous medium, such as z-.E ' Air or steam, which is used to dry or heat the Wrap or harden one in the wrap ~ essential resin is used

Examples of organic solvents that can be used are, in particular, benzene, white gasoline and other petroleum fractions and halogenated hydrocarbons, in particular chlorinated and chlorofluorinated hydrocarbons, for example Trichlorethylene, chloroethylene, methylene chloride and 1,1,2-trichloro-1,2,2-trmuoroethane. Gaseous media that can be used are e.g. air, water vapor, organic solvent vaporβ, formaldehyde and chloro

After the packs have been treated with a liquid, it is expedient to remove at least some of the liquid from the packs before they are removed from the treatment tube. This can be effective through a liquid / liquid displacement and / or by a gas purge he y 'follow with ein.Gas can be used at room temperature or elevated temperature ^ door "The gas can for example air, ■ water vapor or steam treatment liquid, the w used worden.istj be or consist of mixtures thereof "the removal of the medium from the Fackung, by applying a vacuum in the treating pipe or, in the case of removal of a liquid, by use of a gas are supported under superatmospheric pressure.
