Definitions
- the invention relates to a method for physical desizing of tissues.
- Textile yarns must be sized before the weaving process, in order to be satisfactory in the subsequent process stage, the weaving mill To maintain running properties.
- known sizing agents are used in aqueous solution (also as a wash liquor or simply Referred to as size or liquor) at concentrations of 0.5 - 50 wt .-% and at temperatures of 20 - 95 ° C by means of a size application device or size machine (Trough, roller applicator, foam applicator, squeegee, Foulard, etc.) applied.
- Finishing means covering the thread with a protective cover sheath so that it is woven by the mechanical Stress in the weaving machine is not damaged and breaks or tears.
- starch Polyvinyl alcohol, polyvinyl acetate, carboxymethyl cellulose, Carboxymethyl starch, acrylates and various polysaccharides used.
- the sizing agent For further processing (dyeing-finishing) of the fabric the sizing agent if possible by washing or desizing completely removed from the tissue. Out Environmental protection, but also for cost reasons, there is a need to recover the respective size and reuse.
- the object of the invention is therefore to provide a Method with the above, adhering to the prior art Problems can be eliminated.
- the advantages of the method according to the invention are that it is not a wet process, i.e. there will be none large amounts of water for washing out the sizing agent needed, and therefore no drying is required. This saves energy and water, which the Benefits the environment.
- the "dry size" can be easy to collect and reuse. In the case of single color Fabrics can be »dry when contaminated with dye Sizes «can be reused for the same-colored yarns.
- the yarns are, for example with PVA or polyvinyl acetate (or other Sizing agents that can later become brittle).
- the fabric goes through a cooling system, in which there is embrittlement of the sizing agent a suitable temperature is cooled, in the case of PVA for example to a temperature in the range from -20 ° C to - 40 ° C.
- the cooling process used is not subject to any particular one Restrictions and will be determined by the professional in accordance with the practical Circumstances selected, for example depending from the chemical-physical properties of the used sizing agent, dimensions and weaving density of the fabric, the rate of heat exchange etc.
- the fabric can simply be used with cooling gases such as vaporized with cold nitrogen or cooling liquids or be wetted to achieve the necessary cooling.
- cooling gases such as vaporized with cold nitrogen or cooling liquids or be wetted to achieve the necessary cooling.
- the cold treatment must last long enough so that sufficient heat can be exchanged and dissipated can. Suitable cooling times are, however, by simple preliminary tests to investigate.
- the temperature of the cooling medium e.g. 1 to 5 min. For very low temperatures or if cooling should take place very quickly, too Liquid gases are used. It is also possible that Allow tissue to pass through a cooling drum or cooling roller.
- Cold treatment makes the sizing agent used brittle or crystalline and can be dried Remove the form mechanically from the fabric.
- Mechanical Methods known per se can be considered such as e.g. Beating, brushing, tapping, application of vibrations, Sucking, kinking, upsetting, stretching, pressing, blowing, etc. There are no particular restrictions.
- the recovered sizing agents from fabrics with undyed or plain colored yarns can be separated easily and reused if necessary.
- the inventive method is not on Minimum throughputs, as is the case with ultrafiltration systems the case is, but can depend on the individual Be tailored to your needs.
- the procedure can therefore also be used in small or medium-sized companies that cannot carry out wet processes for desizing.
