Definitions

  • the present inventive concept relates to a process for dyeing and/or finishing a textile material.
  • Dyeing and finishing a textile material is made to provide the textile material with one or several preferred features. Some examples of preferred features are colour, glaze, water-repellence, flame resistance, and softness. Often, different agents for different end purposes are applied to the textile material in the form of an impregnation liquid. There are several different methods for this impregnation, for example spraying, padding, roll coating, knife coating or screen coating.
  • a common discontinuous process for dyeing and finishing a textile material is beam dyeing.
  • beam dyeing a textile material is rolled onto a perforated beam and transferred into a vessel that is closed and pressurized. The colour then impregnates the fabric as the dye liquor is pumped into the centre of the beam, out of the perforations, and through the textile material.
  • the vessel used in beam dyeing is usually made to hold a large volume of dye liquor, all of which is heated in the dyeing process. This results in a very energy inefficient process for dyeing textiles.
  • the present inventive concept seeks to provide a process which is more efficient and easier to use for dyeing and/or finishing a textile material.
  • An object of the inventive concept is to overcome the above problems, and to provide for a process for dyeing and/or finishing a textile material which, at least to some extent, is less complex than prior art solutions.
  • the present inventive concept is based on the insight that the process for dyeing and/or finishing a textile material can be made less complex, and more cost, time, and energy efficient, if the mixture used in dyeing and/or finishing the textile is applied to a textile material which is then rolled up to a beam followed by a fixation step in which the treated textile roll is placed in a heating chamber for a predetermined amount of time.
  • a discontinuous process for dyeing and/or finishing a textile material comprises the steps of:
  • a discontinuous process for dyeing and/or finishing a textile material which requires less energy in comparison with traditional dyeing and/or finishing processes. That is because the amount of mixture used in the claimed process is lower than in traditional dyeing and/or finishing processes. Because of the lower volume of mixture, the energy needed for heating the treated textile roll to its fixation temperature and maintaining the fixation temperature during is reduced. In other words, the energy used in swelling the fibre to render it more receptive and transferring for example dye molecules from the mixture to the fibre is reduced.
  • the step of heating the treated textile roll until the fixation temperature is reached can be performed with a fixed predetermined temperature for fixation in the heating chamber. This means that no gradual heating of the treated textile roll is necessary which saves time.
  • the claimed process is thus time efficient.
  • fixation refers to the process when the mixture sets to the treated textile material.
  • fixation is the bonding between the fibre and an active agent in the mixture, such as a dye.
  • Reactive dyes generally fix to a textile by covalent bond, while in the case of acid dyes, fixation is often done by a variety of mechanisms such as hydrophobic forces and ionic bonding.
  • Disperse dyes are non-ionic. At higher temperature the amorphous part of the fibre expands and the dyes can diffuse into the fibre.
  • the mixture being set to said treated textile material is to be understood as meaning that the mixture has bonded or at least diffused and migrated into the fibres of the textile material.
  • fixation temperature the temperature necessary for the fixation to take place.
  • set, fixation, fixation temperature, and similar expression are used in their conventional meaning within the field of textile dyeing.
  • the amount of energy needed for heating until the mixture is set to the treated textile material i.e. the fixation, is less than when the application and fixation are conducted simultaneously in a batch, as in the beam dyeing process.
  • the claimed process is thus beneficial in that only the mixture to be fixed onto the textile material must be heated.
  • the fixation temperature of the treated textile roll in the heating chamber can be reached very quickly.
  • the step of applying the mixture to the textile material which often requires a gradual heating in traditional dyeing and finishing processes in order to obtain a good distribution of mixture, is completed prior heating.
  • the fact that the mixture is applied to the textile material before the treated textile roll is placed in the heating chamber is an advantage in that no step of gradual heating is needed. Consequently, a plurality of treated textile rolls may be placed in the heating chamber and heated until the mixture is set without intermediate cooling of the heating chamber. Furthermore, since the mixture is applied to the textile material before the treated textile material is rolled onto a beam and the treated textile roll is placed inside the heating chamber, no or a limited amount of mixture is in contact with the heating chamber. In other words, the heating chamber is not contaminated.
  • the heating chamber is an autoclave.
  • the heating chamber is cylindrically shaped.
  • the heating chamber is arranged to heat the mixture up to at least 105°C, or at least 130°C. These temperatures are suitable to open the polyamide fibres or the polyester fibres.
  • opening of fibres means that the amorphous parts of the fibres are above their glass-transition temperature.
  • Textile materials which also could be referred to as textiles or fabrics, comprise textile materials manufactured by different technologies such as weaving, knitting, crocheting, or nonwoven technologies.
  • the fibres used in the textile material can be synthetic or natural fibres or mixtures thereof. Some examples are polyester, cotton, nylon, viscous, wool etc.
  • the step of applying a mixture to the textile material could be referred to as a step of impregnating the textile material, i.e. application could be referred to as impregnation.
  • a mixture for dyeing purposes may contain natural dyes and/or synthetic dyes.
  • Natural dyes comprise dyes made from natural substances, usually from the bark, leaves, roots, flowers, or wood of a plant. Natural dyes could also originate from insects such as cochineal and lac.
  • said mixture comprises an aqueous solvent.
  • the aqueous solvent penetrates the fibre and provides rapid wetting of the textile material. This provides a more efficient step of applying the mixture. Furthermore, the aqueous solvent increases the mixture's tendency to penetrate the textile material rather than staying at its surface. Consequently, the aqueous solvent has the effect that dyes or other chemical agents are efficiently transported into the fibres.
  • An aqueous solvent could be water or any other solvent comprising water.
  • a wetting agent or surfactant may be added to the textile material if it has poor wetting characteristics.
  • An alcohol is commonly added to the mixture to improve the wetting characteristics of the textile material.
  • a mixture comprising an aqueous solvent has low impact on the environment as well as on the operators involved in the claimed process.
  • a mixture comprising an aqueous solvent such as water is less environmentally hazardous than a mixture containing a non-aqueous solvent. It is safer to handle and has less environmental impact than a mixture containing a non-aqueous solvent, such as toluene, trichloroethylene, and petrochemical solvents.
  • the aqueous solvent reduces the impact on the environment and on the operating people of the claimed process. Hereby, the environmental effect of the mixture and the claimed process is minimised.
  • a step of cleaning said heating chamber is performed after the treated textile roll is cooled and removed from the heating chamber. This cleaning step is easier to do when the step of applying a mixture to the textile material has been made with a mixture containing an aqueous solvent.
  • the mixture comprises a non-aqueous solvent.
  • non-aqueous solvents are toluene, trichloroethylene, and petrochemical solvents.
  • said step of applying a mixture to at least one side of said textile material is such that said treated textile material has a wet pick-up of at least 5%, or at least 10%, or at least 15%, or at least 20%, or at least 25%. Additionally, or alternatively, said step of applying a mixture to at least one side of said textile material is such that said treated textile material has a wet pick-up of at most 150%, or at most 130%, or at most 110%, or at most 90%, or at most 70%.
  • the wet pick-up is the weight of the untreated textile material in relation to the total weight of the textile material and the mixture applied thereon.
  • the wet pick-up should be around 50%.
  • a wet pick-up that is too high may cause difficulties in handling the treated textile material or the treated textile roll, since the mixture applied to the treated textile material is prone to drop.
  • said step of applying at least one mixture is performed by spraying, padding, knife coating, roll coating, or screen coating.
  • Spray application has the advantage that it is a non-contacting application method and requires low volume of mixture. Furthermore, spraying allows for an even distribution of the mixture regardless of potential absorption variances of the textile material. Spraying is thus an effective method of application. Additionally, spraying causes little spill of the mixture during application. The textile material can be sprayed with spill only at the edges of the textile material. By having the spilled mixture recirculated to the spray nozzles, the amount of lost mixture during application is kept on a low level.
  • the step of applying a mixture by spraying can be performed by means of a spray manifold comprising one or more spray heads, also referred to as spray nozzles, located in a row (in the case of a plurality of spray heads).
  • a spray manifold comprising one or more spray heads, also referred to as spray nozzles, located in a row (in the case of a plurality of spray heads).
  • spray nozzles located in a row (in the case of a plurality of spray heads).
  • the step of spraying is possible to conduct with an overlap of applied mixture.
  • the number of spray heads can be adjusted according to the width of the textile material.
  • a spray system is used for spraying a mixture to the textile material.
  • the spray system can use different techniques such as rotary disc, air atomizing, and ultrasonic or hydraulic nozzles.
  • the spraying is conducted with an overlap of applied mixture wherein the concentration of mixture at the areas not overlapping are higher than concentration of mixture at the overlapping areas.
  • concentration of mixture at the areas not overlapping are higher than concentration of mixture at the overlapping areas.
  • the amount of solvent in the mixture for spraying is reduced.
  • concentration of for example dye in the mixture can be held higher than the concentration of dye in the mixture of the beam dyeing process.
  • concentration of agents in the mixture to be applied by spraying can be held higher than the concentration of agents in a mixture to be applied by beam dyeing. I.e. less solvent is used in the mixture which is to be applied by spraying than in beam dyeing.
  • the reason for the high concentration of agents in the mixture to be applied by spraying is, in comparison to beam dyeing, that the spray application is instant and non-circulating. On the contrary, beam dyeing needs a lower concentration of agents in the solvent because the application method requires that the agents are applied little by little stepwise.
  • the spraying step is performed with the textile material placed in a vertical position such that the textile material is not in contact with the surface beneath.
  • the mixture can be applied to both sides of the textile material.
  • the spraying step is performed with the textile material placed in a horizontal position.
  • Applying said at least one mixture by means of spraying is such that the mixture level is substantially evenly distributed across the width of the textile material. This allows the textile material to be uniformly dyed or finished.
  • Padding also referred to as pad batch or pad dyeing, is a contact application method. It refers to the use of a machine for impregnating textile materials with for example a mixture such as a dye. It consists essentially of a trough, which is filled with a mixture and through which a textile material is fed, followed by two or more pairs of squeeze rolls for distributing the mixture across the width of the textile material.
  • Padding is an application method that is suitable for pre-preparation of the textile material, such as pre-moisturizing, in which the trough is filled with water.
  • said mixture has a viscosity of 0.1*10 -3 Pa*s to 1000*10 -3 Pa*s, measured at 20°C. Additionally or alternatively, said mixture has a viscosity of at least 0.1 *10 -3 Pa*s, or at least 1*10 -3 Pa*s, or at least 10*10 -3 Pa*s, or at least 100*10 -3 Pa*s, or at least 1000*10 -3 Pa*s, measured at 20°C.
  • said mixture has a viscosity of at most 1000*10 -3 Pa*s, or at most 100*10 -3 Pa*s, or at most 10*10 -3 Pa*s, or at most 1*10 -3 Pa*s, or at most 0.1*10 -3 Pa*s, measured at 20°C.
  • the mixture may be in the form of liquid, foam or collapsed foam.
  • said step of applying at least one mixture is performed to a surface of a first side of said textile material so that a first treated surface is obtained; and wherein said step of applying at least one mixture is performed to a surface of a second side of said textile material so that a second treated surface is obtained.
  • the mixture applied on both surfaces of the textile material With the mixture applied on both surfaces of the textile material the mixture is distributed on two surfaces of the textile material, i.e. a first treated surface and a second treated surface. With the mixture applied on both surfaces of the textile material, the distance the mixture and agents therein must migrate, to reach the fibers situated in the middle of the textile material, is decreased. Thus, a more even distribution of the mixture across the thickness of the textile material is achieved.
  • the step of applying the mixture to the first and second side of the textile material may be conducted simultaneously or sequentially.
  • the textile material is in the step of rolling the treated textile material onto a beam subjected to the mixture applied on its own surface and the mixture applied onto the second side of the up rolled material.
  • said mixture is evenly distributed over the surface of said textile material.
  • the variance of the wet pick-up of the treated textile material, measured in percentage points is less than 400, preferably less than 100, and most preferably less than 25.
  • said at least one textile material is at least a first and a second textile material.
  • a plurality of treated textile materials may be rolled up onto the textile roll before the textile roll is placed in the heating chamber.
  • a plurality of treated textiles may be fixed simultaneously which saves both time and money.
  • the claimed process is suitable for large as well as small batches of textile materials.
  • the claimed process performed on small batches of textile material is both time and cost efficient in relation to traditional processes performed on small batches of textile material.
  • said discontinuous process further comprises the step of: rolling at least one foil to said treated textile roll before at least one second treated textile material is rolled to said treated textile roll.
  • the foil between different batches of treated textile materials on the treated textile roll is advantageous for keeping the treated textile materials separated from each other, especially when the mixture of the first treated textile material is different from that of the second treated textile material.
  • a plurality of treated textile materials can be fixed in the heating chamber at the same time, even if the different mixtures comprises different agents.
  • the foil applied between the first and the second treated textile material on the treated textile beam minimises the risk that the mixtures are mixed up with each other, neither during the step of rolling the treated textile material onto the beam nor during the steps of heating or maintain the fixation temperature of the treated textile roll within the heating chamber. Since the first treated textile material is separated from the second treated textile material the mixture applied to the first treated textile material cannot migrate to the second treated textile material. Neither can the mixture of the second treated textile material migrate to the first treated textile material.
  • a first colour of the first treated textile material is not able to contaminate a second colour of the second treated textile material.
  • the foil which may be referred to as a seal or a sealing layer, could be a plastic foil.
  • said second distribution is a pressure distribution.
  • the second distribution of the mixture to the textile material is obtained when the textile material is rolled up onto the beam.
  • the pressure that is applied to the treated textile material during the step of rolling the treated textile material onto a beam promotes a second distribution of the mixture thereon.
  • the pressure distribution promotes a backup if the first distribution of mixture to the surface of the textile material is poor.
  • a discontinuous process which further comprises the steps of:
  • Rotation of the treated textile roll within the heating chamber during the fixation step makes thermal impact uniform, hence improving the efficiency and quality of the fixation step.
  • the rotation of the treated textile roll may function as an internal fan, i.e. the rotation promotes natural convection of the air surrounding the treated textile roll.
  • an external fan is unnecessary which makes the claimed process silent.
  • said step of applying at least one mixture to at least one side of said at least one textile material is performed in a temperature between 10 - 40°C.
  • the step of applying a mixture can be performed in room temperature without the influence of additional heating.
  • said step of applying at least one mixture comprises at least a first application with a first mixture and a second application with a second mixture.
  • a first mixture comprising a dye can be applied to the textile material and subsequently a second mixture comprising a finishing agent can be applied to the textile material.
  • the textile material can be both dyed and finished in the claimed process.
  • said textile material is pre-moisturized before said step of applying at least one mixture to at least one side of said at least one textile material pre-moisturizing said textile material before said step of applying a mixture to at least one side of said at least one textile material.
  • the pre-moisturizing of the textile material contributes to a better absorption of the mixture, as the mixture may easily and thoroughly penetrate the textile fibers if the textile material is pre-moisturized before the step of applying a mixture. This is because water promotes the swelling of fibers, and therefore the transportation of dye into the fiber is facilitated and improved with a pre-moisturized textile material, especially if the fiber is of hydrophobic character.
  • An example of a fibers that could be difficult to dye without being pre-moistened are wool fibers.
  • the textile material must not be dry when the step of application starts. Consequently, the manufacturing or the preparation of the textile material before the claimed process starts is not dependent on drying of the textile material which saves time, money, and energy.

At the same time as the temperature is raised, the mixture is pumped into the centre of the beam, out of the perforations, and through the textile material. Alternatively, the mixture is pumped through the textile material in reversed direction.

  • the mixture 10 applied to an up rolled treated textile material (5, 6, 7, 8) is not in contact with the mixture 10 applied to other up rolled treated textile materials (5, 6, 7, 8). This has the effect that there is low risk of cross-contamination of the mixtures 10 of the treated textile rolls 50.
  • Fig. 1a is a diagram showing the process of dyeing a textile material according to the prior art process of beam dyeing.
  • a textile material to be dyed is provided.
  • the textile material is a polyester, PES130.
  • the textile material is rolled around a perforated beam such that a textile roll is obtained.
  • the textile roll is placed in a beam dyeing machine together with a mixture.
  • the mixture contains a dye and auxiliaries.
  • the mixture is applied and distributed to the textile roll in a step of applying a mixture to a textile material. This step takes about 15 minutes. Thereafter, the mixture and the textile roll therein are slowly heated for one hour and five minutes from room temperature till a fixation temperature of 130°C.
  • the mixture is pumped into the centre of the beam, out of the perforations, and through the textile material.
  • the step of applying a mixture to a textile roll is finished. Accordingly, a treated textile roll having a fixation temperature is obtained.
  • the fixation temperature of the treated textile roll is maintained for 55 minutes until the mixture is set.
  • the treated textile roll is cooled down from 130°C to 60°C for 35 minutes. The overall process takes two hours and 50 minutes.
  • Fig 1b is a diagram showing the process according to the present invention.
  • a textile material to be dyed is provided.
  • the textile material is a polyester, PES130.
  • a mixture is applied to the textile material such that a treated textile material is obtained.
  • the step of applying the mixture to the textile material takes 15 minutes.
  • the mixture contains dye, auxiliaries, and effect chemicals dissolved in the mixture before it is applied to the textile material.
  • the step of applying the mixture to the textile material provides a first distribution of the mixture to the textile material.
  • the treated textile material is rolled around a beam which provides a second distribution of the mixture to the textile material.
  • the treated textile roll is then placed into a heating chamber and heated therein from 20°C till the treated textile roll has reached a fixation temperature of 130°C.
  • the heating of the treated textile roll takes 20 minutes.
  • the fixation temperature is maintained for 55 minutes until the mixture is set to the treated textile material.
  • the treated textile roll is cooled from 130°C to 60°C. The overall process takes one hour and 45 minutes.
  • the process according to the present invention illustrated in Fig. 1b is one hour and five minutes quicker and less energy consuming since there is less need for heating a large amount of mixture.
