Definitions

  • the invention relates to a process for the treatment of sheet, ribbon or thread-shaped polymeric products, in particular products made of synthetic fibers, preferably made of synthetic fibers, or polymer films by exposure to fine particles of organic or inorganic solids.
  • CH-A-34 99 47 describes a device for treating thread-like or web-like material, in which the material is passed through a layer of swirling particles which are held in suspension by an upward gas stream.
  • the aim is to avoid the formation of a unidirectional flow, for which facilities are provided in the vicinity of the goods which prevent a greater horizontal movement of larger quantities of particles towards and away from the goods.
  • the material is thus passed through the suspended particles in the form of glass spheres, so that only a gentle contact takes place, which cannot cause the surface of the material to be roughened.
  • polyester and polyamide fibers are among the top synthetic fibers.
  • the filaments of these two fibers are cylindrical and have a smooth surface, apart from the low proportion of profile silk spun with special nozzles.
  • these fibers and the products made from them have a shiny effect and they feel smooth (soapy, greasy).
  • the spin-matted fibers also have one considerable shine.
  • fabrics made of natural fibers, especially wool and cotton have a matt appearance and a rough (woolly) feel.
  • the sheen and feel of textile fabrics are properties that are dictated by fashion.
  • the general idea of high quality textile products is based on those made from natural fibers.
  • the development of chemical fibers and their modification was and is therefore aimed at the production of fibers and products that combine new, positive usage properties and proven (and familiar) properties of natural fibers.
  • the object on which the invention is based is therefore to design the method of the type mentioned at the outset and the device for carrying out the method in such a way that products with a matt and rough surface can be produced without destruction.
  • Sand, corundum, glass or metal particles can be used as solid particles.
  • the individual solid particles can consist of a single substance or of several substances. Mixtures of different solid particles can also be used.
  • the solid particles can consist wholly or partly of substances which are partially transferred to the sheet-like, tape-like or thread-like polymeric products when they are loaded.
  • the application can also take place in that the endless sheet-like, ribbon-like or thread-like polymeric products are continuously passed through stationary or moving solid particles.
  • the sheet-like, tape-like or thread-like polymeric products can also be applied in the swollen state. It is expedient to apply preparation agents to the sheet-like, tape-like or wheel-shaped polymeric products before the application of solid particles, or to dye them, or to print or coat them.
  • the device for producing matt and rough flat or band-shaped polymer products in which an abrasive is thrown by a gas stream from a nozzle onto a fabric guided over a deflection roller, is characterized in that a deflection roller projects into a radiation chamber, the gap between the deflection roller and the radiation chamber is sealed by special sealing strips.
  • the inside of the radiation chamber is provided with a wear protection lining.
  • an acceleration channel protrudes into the radiation chamber. The distance between the exit edge of the acceleration channel and the deflection roller is adjustable.
  • the acceleration channel is constructed as a flat channel with a rectangular cross section, in which solid particles are accelerated by a gas stream, for example an air stream.
  • the channel exit edge is parallel to the cylinder axis of the deflection roller.
  • the opening of the radiation chamber, through which the acceleration channel protrudes, is covered with a cover that both close to the radiation chamber and the acceleration channel.
  • the bottom of the radiation chamber is funnel-shaped. This removes the gas that carries blasting media and dust.
  • roller heating By limiting the roller heating to selected areas of the roller surface, pattern-like areas with more intense roughening and matting effects and / or pattern-like areas in which reactions between the polymer and substances that are wholly or partly part of the solid particles or the gas stream take place are achieved in the fabric .
  • Reactions between the polymeric sheet and substances that are wholly or partially part of the solid particles or the gas stream can also be triggered by reactive species being formed by high-energy rays, preferably by electron beams, in the sheet structure before being exposed to solid particles or in selected areas will.
  • Roughing and matting effects arranged in a pattern can be achieved by means of a perforated stencil which is arranged in the application area in front of the fabric.
  • This template can be arranged stationary or it can move synchronously with the fabric or relative to the fabric.
  • the object is also achieved in that a web-shaped flexible sheet is moved over a curved hard surface of a deflecting roller and is brought into contact with a stationary air vortex on this surface. Solid particles are placed in this stationary air vortex, which act on the fabric during each revolution.
  • a suction pipe In the center of the vortex there is a suction pipe, the cross section of which is dimensioned such that the solid particles, when they have reached the wear limit with regard to their size, are conveyed out of the vortex with the exhaust air and are removed from the air by known separating devices.
  • a fresh air and a solid particle supply duct as well as a suction tube which generates a vacuum in the housing by suction are arranged in a housing which has an opening for the solid material to act upon the web.
  • the suction pipe is attached to the central axis of the housing and has a suction slot.
  • the solid particle supply duct opens into the fresh air supply duct.
  • an undyed fabric made of polyester silk 1 with a mass per unit area of 60 g / m 2 and a width of 1 m is passed over a rotating drum 2 and corundum particles of 0.5 mm particle size are applied in area A.
  • the corundum particles are fed via a 1 m wide inflow container 3 and accelerated by an air stream emerging from the 1 m wide nozzle 4.
  • the air is at room temperature.
  • the treatment makes the fabric matt and rough to the touch on the side exposed to corundum particles. It also becomes softer and denser and the position of the threads relative to one another becomes more even.
  • a polyester film 1 m wide and 40 ⁇ m thick is first treated on one side in the same way as in Example 1. However, it is loaded with micro glass balls of 0.1 mm in diameter. The other side of the film is then treated in the same way. This treatment makes the film matt and rough on both sides, and the transparency is reduced.
  • a dyed and coated polyamide silk fabric on one side is first exposed to quartz sand particles of 1.5 mm in size A on the coated side as in Example 1. Subsequently, quartz sand of 0.7 mm particle size is applied to it on the uncoated side in area B (FIG. 1). This treatment on both sides makes the fabric softer, rough and matt. The water permeability through the coating is retained.
  • An undyed knitted polyester fabric is treated analogously to Example 1. However, it is loaded with quartz sand particles of 0.5 mm in size, which were previously treated in a dispersion of disperse dye and then dried. The particles are accelerated with hot air at 190 ° C. The effects mentioned in Example 1 are achieved and the knitted fabric is also dyed.
  • An undyed polyester fabric is treated analogously to Example 1. However, a mixture of quartz sand particles and disperse dye granules (mixing ratio 1:10) is applied. The particles are accelerated with air at room temperature. The dye is fixed on the fabric by the known thermal aftertreatment. The treatment leads to the effects mentioned in Example 4.
  • a polypropylene thread 5 (FIG. 3) is passed through the chamber 6 filled with quartz sand particles of 0.7 mm particle size.
  • the sand particles are heated to 125 ° C. by the jacket heater 7. This treatment gives the thread a fine-grained surface, which makes it matt and rough.
  • FIG. 4 shows a section through the device and FIG. 5 shows a side view of the device.
  • the web 8 is moved with tension by known means over the deflection roller 9.
  • the deflecting roller 9 protrudes on the side where the material web 8 rests into the radiation chamber 10, the bottom 11 of which is designed in a funnel shape for the removal of air, blasting medium and dust.
  • the radiation channel 12 projects through an opening into the radiation chamber 10. This opening is closed with a divided cover 13.
  • the acceleration channel 12 is easily exchangeable.
  • acceleration channels of different widths can be installed very easily. As a result, the radiation conditions can be changed over a wide range.
  • the blasting medium for example corundum particles, which is caught by the air flow, is thrown through the acceleration channel 12 and the acceleration chamber 10 onto the material web 8. After stepping onto the web 8, the blasting agent falls onto the floor 11 of the radiation chamber 10 and is removed from there by known methods.
  • a flexible fabric web 14 is moved over a deflection roller 15 according to FIG.
  • zone A it is in direct contact with a stationary air vortex 16 which is guided through a housing 17.
  • the suction tube 18 In the center of the vortex 16 is the suction tube 18 with the slot 19, which is dimensioned so that the vortex has the same pressure and thus the same speed over the entire width.
  • the suction creates a negative pressure in the housing 7, whereby fresh air that drives the vortex flows in through the channel 20.
  • solid particles are introduced into the air stream, which circulate with the vortex inside the housing 17 and impinge on the web 14 in each zone A zone.
  • the worn particles are guided with the air flow through the slot 19 into the suction pipe 18 and conducted out of the device with the exhaust air.
  • the device In operation of the device, after the required amount of particles has been added to the vortex, only the wearing amount of particles has to be added through the channel 21.
