Definitions

  • the subject matter generally relates to an apparatus for textile processing and method manufacturing the apparatus. More specifically, the subject matter relates to an apparatus method of manufacturing the apparatus for impregnation of fluids and chemical into yarn and/or textile and/or fabric.
  • yarns used in textile industry have become finer, denser, stronger and with less hairiness. Denser and stronger yarns can now withstand stressed environment of weaving machines. Yarns are applied with the bonding chemical and/or synthesized and/or natural starch to make them strong enough to withstand stresses of high speed weaving preparatory and weaving machine. This has not only resulted in increased speed of production of textile, but also made possible to increase density of the textile. Both, the yarn and the textile thereof have become so dense that intra-yarn space, i.e. space within yarn and inter-yarn i.e. space in between adjacent yarns, have considerably reduced.
  • Reduced inter-yarn and Intra-yarn spaces are desirable for a number of reasons, such as fine finish and otherwise improvement in other qualities. At the same time, it also limits absorption capacity of yarn and the textile thereof. Limitation on the absorption capacity of the yarn and the textile is undesirable in course of textile processing. A number of processes often get adversely affected by reduced absorption capability of a yarn or textile. Such processes include wet processing such as singeing, de-sizing, bleaching, mercerizing, dyeing, and washing etc. A number of techniques for increasing the absorption capacity of yarn and the textile have been applied by the industry. However, these techniques are either technology intensive, expensive, less-commercially viable or have problems relating to scaling from laboratory conditions to the industry conditions. Patent documents relating to the Numbers EP 0 969 131 A1 , US 3 688 527 , and WO99/37844 show some solutions which are discussed in more details with reference to subject matter at the end of the specification.

  • the power of ultrasonic is effectively utilized because, the textile 131 is disposed in accordance with the wavelength of the ultrasonic and size of the tank in which the ultrasonic is radiated on the textile 131 is selected based on the wavelength.
  • the power of the ultrasonic is distributed substantially uniformly, without much attenuation in the first tank 101 because, the size of the first tank 101 is in the order of the multiples of wavelength of the ultrasonic, therefore, standing wave formation and substantially uniform cavitation occurs in the first tank 101.
  • the wetting agent and other chemicals may added at block 200.
  • amount of wetting agent and other chemical required for processing textile according to the subject matter may be considerably lower as compared with conventional methods.
  • the subject matter may demonstrate reduction in the quantity of wetting agent up to one fifth or up to one fourth of the normal usage in industry.
  • Water flow rate to block 200 from degas tank may be regulated with valve 309 based on textile Kg/Hour rate.
  • Diffusion is phenomenon, which occurs in textile, without regards to the volume of the fluid.
  • ultrasonic power required is higher for higher volume of the fluid is used. Therefore, it is desirable to keep the volume of the fluid at its lowest as smaller volume while leave the diffusion unaffected it assist in conserving power of the ultrasonic transducer. While it is desirable that the volume of the fluid is kept at its minimum, however reduction in volume of the fluid must accompany with increase in the velocity of fluid through the tank in order to keep up effective concentration of fluids. However, increased velocity of fluid through the tank diminishes ultrasonic effect. That is beyond certain point further reducing the volume of the fluid in the tanks become counterproductive because the fluid velocity required starts disrupting the effect of ultrasonic on the textile. Providing the size of the tank in the order of the wavelength and disposing the textile according to the subject matter addresses this conflict between the velocity of fluid, volume of fluid and ultrasonic power and provides an effective solution for impregnation of textile.
  • FIG. 4 shows schematic diagram for the ease of understanding of the subject matter. Shown in FIG. 4 are: an ultrasonic transducer 503 that produces ultrasonic waves of wavelength ⁇ , a proximal wall 505, distant wall 501, textile iterations 502, 507, 509, 511 and/or 519.
  • the transducer 503 is coupled to the proximal wall 505.
  • the distance between transducer 503 and the proximal wall 505 is negligible.

  • the distance between the distant wall 501 and proximal wall 505 may be an integer multiple of the wavelength ⁇ .
  • the standing wave pattern creates pressure antinodes at (n X ⁇ /2) and pressure node at (2n+1) ⁇ /4. (Where "n” is an integer).
  • This way effective ultrasonic pressure at multiple of ⁇ /2 distances will be almost twice, giving rise to cavitations at regions where textile 502, 507, 509, 511 and/or 519 are disposed.
  • ultrasonic pressure difference between pressure antinodes at n ⁇ /2 and pressure nodes at (2n+1) ⁇ /4 helps in uniform distribution of fluid concentration with low velocity micro-flow. Geometrical placement of yarn/fabric/textile is guided so that yarn/fabric/textile remains at place of pressure antinodes which are higher cavitation zones.

  • the above processes are generally governed by physical processes of fluid exchange between textile by convection and diffusion.
  • impregnation of fluid in-between yarn (inter-yarn) portion of textile results from convection, which is comparatively faster physical process than diffusion.
  • impregnation of fluid within yarn (intra-yarn) which is major part of total impregnation and it results from diffusion. That is, the main process of impregnation involves diffusion.
  • the diffusion depends on yarn surface characteristics and is generally difficult to enhance.
  • the subject matter provides solution to this problem by effectively employing the ultrasonic for enhancing both the physical processes of impregnation to textile, convection and diffusion.
  • the subject matter provides a number of flexibilities in processing the textile, for example, the amount of absorption of fluid by the textile may be improved without making extensive changes in the system.
  • existing solutions require repeating the wetting processes or running the textile multiple times through fluid.
  • Current industrial processes are based on method of concentration exchange between the textile and fluid by moving textile multiple times through the fluid.
  • the subject matter provides improvement over these processes.
  • the existing methods not only fail to provide desired results but also, hamper production, waste fluids, water wastage is high, power consuming, result in higher chemical usage and environmentally hazardous effluents, resource intensive in terms of size of equipment, cost of running, infrastructure etc, higher temperatures of process, and higher textile contact time with fluid for increasing impregnation. Therefore, these methods are undesirable.
  • the subject matter further addresses challenges related to developing an industry scale application of ultrasonic based impregnation of textile.
  • Industry application of ultrasonic based textile impregnation is challenging because the ultrasonic pressure wave may cause the textile to move.
  • Such characteristic of textile calls for power requirement of ultrasonic in terms of Watts/cm 2 instead of normal standard cleaning calculation in Watts/liter.
  • industrial web width and roller size is generally higher than 1800 mm and 100 mm respectively. Therefore, for industry applications up-scaling of ultrasound impregnation apparatus results in ultrasonic power requirements prohibitively higher than what is practical.
  • the subject matter solves this problem by optimally adjusting and selecting geometry of the tank and the transducers, and iterations of textile into the tank, to exploit cavitations caused by the ultrasonic waves such that ultrasonic power required in an unit area of textile (Watts /cm 2 ) for a given contact time is achieved without compromising on the ultrasonic power required in the tank for a give unit of fluid (Watts/liter).

  • the method provides adapting the disposer to dispose each of the iterations of the textile at a location that corresponds to location of an anti-node of the substantially standing ultrasonic wave pattern formed in the first tank.
  • the method further includes configuring the first transducer and geometry of the first tank to cause the textile to ultrasonic power in a range between 0.2 Watts/cm2 and 2 Watts/cm2 and transmit at least 8 watts/liter of ultrasonic power into the first tank.

  • Patent documents relating to the numbers EP 0 969 131 A1 , US 3 688 527 , and WO99/37844 show some solutions. While these documents attempt to reach at some solution that employ ultrasound in cleaning, these documents suffer from a number of limitations, including those discussed previously relating to laboratory scale experiments and non-viability on commercial scale and other technical challenges.
  • EP 0 969 131 A1 discloses a device for treating textile, comprising a tank (2) for holding treatment liquid (3), conveyor means (4) for conveying a textile substrate (7) which is to be treated through the tank (2), a transducer (8) for generating ultrasonic vibrations in the treatment liquid (3), an interference element (19) placed opposite the transducer for together delimiting a vibration cavity (13), wherein the transducer (8) together with the interference element (19) is designed to generate an interference pattern in the vibration cavity (13) of ultrasonic vibrations amplifying each other, in which a concentration area (11) of intensified vibration energy occurs at a distance from the transducer (8) and the interference element (19), in which the conveyor means (4) are designed to guide the textile substrate (7) through the concentration area (11), and in which energy of the ultrasonic vibrations is destined to dissipate by means of cavitation in the concentration area (11) at the location of the textile substrate (7).
  • EP 0 969 131 A1 attempts to employ ultrasonic wave solution in textile industry, it fails to recognizes challenges relating to obtaining a stable concentration area (11), in which energy of the ultrasonic vibrations is destined to dissipate by means of cavitation. Because the concentration area (11) is highly susceptible to physical parameters of the medium. The position of concentration area (11) changes with temperature pressure etc. In fact in some case, concentration area (11) may not be in a substantially vertically aligned, as envisioned by the EP 0 969 131 A1 , due to changes in temperature of the medium at different heights in a given tank.
  • EP 0 969 131 A1 provides a complex solution which employs a number of transducers each focusing in different direction, interfering elements and ultrasound unit 9.
  • the present subject matter solves at least both the problems associated with the EP 0 969 131 A1 .
  • the present subject matter configures the walls of the tank itself eliminating need of a separate ultrasonic unit 9 altogether.
  • the apparatus of the present subject matter operates on a sweep frequency.
  • the ultrasound unit 9 of EP 0 969 131 A1 requires multiple combinations of transducers and interference elements (the interference element being transducers themselves) and some focusing arrangement to guide the ultrasonic waves in specific direction, into the tank.
  • This arrangement of the EP 0 969 131 A1 not only makes the solution of the EP 0 969 131 A1 practically not workable but also makes it more complex. This is because, when a number of transducers each of them focusing in different directions (see, Fig 1 items 8 of EP 0 969 131 A1 ) pass a number of ultrasonic waves through a single continuous medium, the medium does not see these waves as separate waves coming from different sources/direction. Instead the medium sees some convolution of waves.

  • the apparatus may be configured to operate based on the sweep frequency and dispose textile using the rollers accordingly in number of ways. It shall become clear to a person in the art that the textile may be kept in the cavitation zone by a number of ways, which may include combination of adjustment of rollers and adjustment of frequency etc.
  • the apparatus may be configured to solve these problems by disposing the textile in a diagonal/oblique manner (shown in FIG. 1a ) so that the textile traverses maximum part though the caviation zone, as is understood that the slope of the diagonal/obliqueness may be determined based on the sweep frequency.
  • the apparatus may be configured to solve these problems by adjusting the roller positions (see, paragraph [0046]). In a further another embodiment the apparatus may be configured to solve these problems by adjusting the textile positions (see, paragraph [0046]). In another embodiment the apparatus may be configured to solve these problems by (see paragraph [0033]) adaptively selecting or altering the transducer frequency, and adjusting the textile positions (see, paragraph [0046]).
  • the EP 0 969 131 A1 also fails commercial viability test because of only single iteration of textile may be treated at a given time, whereas the subject matter efficiently utilizes energy and time by enabling disposing of textile in multiple iterations without compromising on the advantages of cavitation zones and therefore the subject matter provides a better and cheaper solution.
  • US 3 688 527 discloses, a method and apparatus for cleaning mechanically bonded contaminants from a resilient web in a fluid medium.
  • US 3 688 527 diverts from the present subject matter, more often than not the textile is rather delicate and not resilient. It is therefore US 3 688 527 shows a sonotrode type of transducer, generally used for cutting and welding operations.
  • Employing US 3 688 527 in textile industry would only result in damaged textile. It is therefore despite of US 3 688 527 being in public since 1972, industrial scale solution employing ultrasounds to process textile are not available in the market.
  • WO99/37844 is another document, the document does not discuss either the problems addressed by the present subject matter or provides a solution thereof. Furthermore, for treating different sides of the textile, the WO99/37844 requires two transducers one for each side of the textile. It does not provide any indication or motivation for disposing the textile based on either sweep frequency or corresponding wavelength.
