  • the invention relates to multifunctional fabrics used in the textile industry.
  • the invention particularly relates to a single-layer multifunctional cotton fabric having at least two functionalities applied to the fabric subsequent to the application of finishing processes such as flame-retardant, antibacterial and water-soil-oil repellent properties, and to the production method thereof.
  • the entire fabric has water-repellent characteristic, then the absorption of the sweat and water formed in the inner side will be prevented. If, on the other hand, the entire fabric is antibacterial, then the fabric surface may exhibit hydrophilic properties (despite at varying degrees depending on the chemical which is used), as well as increasing the cost of the process as the amount of chemicals to be used will unnecessarily increase. Therefore, while it is not among the customer requirements providing antibacterial property on the upper surface of the fabric, both sides of the fabric is treated with the same chemical since the commonly used application methods today do not permit transferring different chemicals to different surfaces; as a result, not only the expected requirements cannot be fulfilled properly, but also the costs increase because of unnecessary material transfer. For this reason, some functionalities must be applied only to a single surface of the fabric.
  • the functionalities of the mixed chemicals will differ in terms of functionality mechanism of the chemicals, their chemical structure will also be different, thus it is faced with a problem to provide a homogeneous mixture.
  • Another one of these disadvantages is that the desired efficiency cannot be achieved to the desired extent because the functionalities will be provided in an irregular order regardless of the back/front surface, or the inner/outer area, of the fabric such that the suitability for the intended area of use cannot be controlled due to mixing together all of the chemicals, in which case the inner side of the fabric may be water-repellent (while it is otherwise expected to absorb water and sweat) while the upper surface may be antibacterial, or none of the functionalities can be achieved adequately. Therefore, it is required to transfer the functionalities to the fabric in an efficient and permanent manner according to the intended area of use.
  • the most frequently used method in the textile industry is the conventional padding method owing to it ease of use. Due to the low affinities of the chemicals used in finishing processes, to the fabric, the conventional padding method is generally used in the industry. However, it has some disadvantages including application to the entire fabric, inability to apply different processes to the front and back surface of the fabric, water consumption, etc. Apart from these, there also exist transferring and coating methods. Transferring methods such as roller transferring and transfer with doctor blade, and coating methods such as blade coating, calender coating, printing technique, and transfer coating are not convenient for chemicals with low viscosity. High viscosity chemicals also have the problem of transferring. The utilized method changes according to the surface of the fabric. Transferring and coating methods in general cannot provide flexibility due to the chemicals and materials used therein.

  • an environmentally friendly plasma method which is used in textile sector as well as pilot studies, and which applies functionality onto the fabric by means of using gas and monomers only, without requiring the use of water.
  • the vacuum plasma treatment applied in this method is a discontinuous method which is not industrialized since it allows a relatively small fabric size in terms of fabric length and width.
  • the atmospheric plasma treatment is suitable for industrial use in terms of work sizes, but it has problems to provide a homogeneous application; in fact, it is not as effective as the vacuum plasma treatment in porous textile surfaces.
  • Microencapsulation which is a newly developed method, is a method in which the microcapsules are produced first, which is a time-consuming chemical formation process, followed by one of the conventional methods for transferring the microcapsules to the fabric. Therefore, water or energy consumption cannot be reduced thereby. It is also possible to apply functionality by using nanotechnology, which aroused great interest in the field of fiber technology, but the use of nanotechnology is still controversial since it has negative effects on human health and environment, as well as having toxicological effects.

Thanks to the invention, it is possible to obtain a single-layer multifunctional cotton fabric with high efficiency and durability, the front and back surfaces of which have the same or different functionalities.
  • Said functionalities include flame-retardant, antibacterial, and water-soil-oil repellent functionalities which are applied to the fabric during finishing processes.
  • the multifunctional fabrics according to the invention are aimed to be produced for use in military, hospitals and other medical fields, firefighter clothing, hotels, vehicles, and generally, in all industrial areas where people are together and safety is required.
  • the fabric with multifunctionality according to the invention is preferably a single- layer cotton fabric. The reason why a single-layer cotton fabric is chosen will be generally explained below.
  • a multi-layer (5-layer or 7-layer) structure is used and each layer is provided with a functionality, and then combining all the layers using various methods.
  • Such production method for obtaining a multifunctional fabric is not only high-cost, but also unfavorable in terms of the time and labor needed for the production.
  • a multi-layer structure may be suitable for some types of clothes or industrial design, in most of the cases requiring protective clothing or protective textile products, such high-volume structures are not convenient.
  • a single-layer structure is inevitable when a flame-retardant and antibacterial curtain is to be produced for use in hospitals.
  • a single- layer structure is advantageous and preferable in every respect due to such reasons as lightness, capability of movement, and water absorption in hotels, beddings, pillow cases, military uniforms, medical gowns, and generally, in all areas where safety is required. The reasons for choosing a cotton fabric as the subject matter of the invention are given below.
  • Cotton fabrics are used in numerous areas owing to the advantages thereof in terms of area of use. Since cotton is a light and comfortable material which is easy to use and clean and has the ability of breathing, absorbing, and antistatic characteristics and allowing flexibility of movement for the user; cotton fabrics are used in hospitals, hotels, military uniforms and firefighter clothing, common use areas, home textile products, automotive textile products, and furnishing fabrics. For example, a textile material for use in operating rooms is expected to fulfill the following requirements.
  • the inner surface of the gown is expected to have breathing and sweat and water absorbing properties, i.e. being hydrophilic, while the outer surface is expected to be blood-, soil-, and oil-repellent for a convenient and comfortable use.
  • cotton fabrics are preferred in order for the bedclothes used in hotels to be comfortable, convenient, and breathing; however, it is desired that these fabrics also have high flame resistance against a potential flame, i.e. that they are flame- retardant, as well as having antibacterial and water-oil-soil-repellent properties.
  • the former fabric properties and functionalities are also expected in firefighting clothes and military uniforms.
  • Comfort is an important property for the professionals who perform long- lasting processes, as well as for the handicapped and the elderly, who are unable to perform normal movements because of their physical condition.
  • Cotton is typically used for eliminating the possible risks due to electrostatic charges. Synthetic fibres, in contrast, tend to increase static charges, and thus forming electric sparks.
  • the gas mixtures used for anesthetic purposes in operating rooms comprises oxygen and has the risk of flammability and explosion.
  • cotton fabric is a material with low flame-retardant property, i.e. it is has a high level of flammability (LOI:18,5). It creates a suitable environment for bacterial growth.
  • a pre-treated cotton surface can readily absorb water and other liquids therein due to the increase in its hydrophilicity. Taking the aforementioned areas where safety is required, it is quite advantageous to incorporate any two or three of these functionalities (flame-retardant, antibacterial, water-oil-soil-repellent, etc.) into the cotton surface.
  • the experimental processes explained below are used for determining the method of producing the single-layer multifunctional cotton fabric according to the invention.
  • antibacterial, flame-retardant, and water-oil- soil-repellent single-layer cotton fabric which is comfortable and light, allows capability of movement; the inner side of which absorbs water while the outer side is resistant against wetting; and which, in its entirety, is flame-retardant and allows less particle and dust penetration therethrough owing to the tightened structure obtained as a result of repeated washing and drying processes; which is also resistant against repeated washing and drying while less water and energy will be consumed; additionally, chemical recipes have been formed, the amounts of all the chemicals therein have been optimized taking their interactions into consideration, and finally achieving and making use of synergistic effects.
  • the sizes of the thus produced cotton fabrics are not limited to laboratory scale; on the contrary, fully industrial sizes have been tried and produced successfully.
  • the produced cotton fabrics are classified into three types of single-layer cotton fabrics: monofunctional (singlet); bifunctional (binary), and trifunctional (ternary).
  • monofunctional single-layer cotton fabrics
  • bifunctional binary
  • trifunctional ternary
  • flame-retardant FR
  • AM antibacterial
  • WR water-oil-soil-repellent
  • the foam application method which considerably saves on water and allows a homogeneous application on the entire fabric has been employed.
  • the foam is a metastable system that swelling of any liquid with a suitable gas and surface area of it has been increased roughly about 1000 times; thus, it's containing less liquid.
  • aqueous liquors are used as liquid while air is used as gas in the foam system.
  • the air is distributed inside the water in the form of water particles by the means of surfactants.
  • the foam application method has been compared to the conventional padding method (or pad- dry-cure system) to show the advantages and the effect and efficiency of the former on functionality.
  • two methods are integrated herein in order to obtain a multifunctional fabric subsequently. As a result of combining two methods, the following has been achieved:
  • the surface is made up of a single layer, unlike the other studies in terms of use, different functionalities are applied to the front and back surfaces in separate steps.
  • the side contacting with the body namely the back surface
  • the entire fabric is flame- retardant
  • the outer surface of the fabric is water repellent.
  • Method optimization While applying functionality according to the indented use of the fabric, first, it was determined which functionality to be transferred to the fabric as a preliminary process. The subsequent functionalities were applied in the determined process order.
  • the method optimization includes optimizing the apparatus parameters, as well.
  • apparatus parameters are set for each application according to the functionality desired to be applied. For example, the parameters such as foam blowing rate, fabric speed, wet pick-up ratios etc. for the foam application for each surface, are detected, while wet pick-up ratio for the solution to penetrate to the entire fabric as well as fabric transition speed are set in the padding apparatus.
  • the padding and foam application methods are integrated or the foam application is employed individually for the front and back surfaces such that multifunctional fabrics (K5,K6) will be produced, if the fabric has a functionality on either surface thereof applied formerly, the amount (%) of the chemical to penetrate into the fabric will differ; and so all apparatus parameters, the ratios/amounts of the used chemicals, and the wet pick-up percentage are also optimized.
  • the multifunctional fabric (K6) was produced by using the foam application apparatus (C1 ) alone, or by integrating the padding (E1 ) and foam application (C1 ) apparatuses, such that the front and back surfaces will vary in many combinations of the three functionalities. Washing and drying resistance of the multifunctional fabrics (K6) has been tested and their efficiency was analyzed using many performance and characterization tests.
  • Monofunctionality Monofunctional fabrics (K3) were produced using only foam application or only padding process. Their washing and drying resistances were tested. Each functionality was subject to performance and characterization tests in itself, the optimization for each functionality (AM, FR, WR) in terms of the used chemical was checked, and 2 methods (foam application and padding) were compared.
  • Fig. 1 shows the production of the monofunctional fabric (K3) using the work flow No. 1 .
  • Three functionalities (AM-FR-WR) combined in a single-layer cotton fabric) combinations were produced by using only foam application (two steps: such that the back and front surfaces will be treated individually) or by integrating foam application and padding methods. Said multifunctional combinations were subject to performance and characterization tests and their results were compared to both monofunctional (K3) and bifunctional (K5) fabrics, as well as analyzing the effects of the methods and chemicals on one another.

It is possible to transfer said functionalities to the entire cotton fabric, or to the front and/or back surfaces thereof. Hence, it is of utmost importance that the functionalities are determined in accordance with the usage area, and which surface will be provided with the related functionality with respect to the desired effect on the fabric.
