Description

A PRINTING PASTE WHICH PROVIDES ELECTRICAL CONDUCTIVITY
TECHNICAL FIELD
The present invention relates to a printing paste which provides electrical conductivity to textile materials without needing conductive fiber or yarn usage.
PRIOR ART
Smart textile products, which exist in the technical textile field and which have substantially high added value, can be defined as textile products which can sense an effect or an effect change like light, heat, pressure, electromagnetic waves, sound, etc. and which can show reaction to this effect or effect change. Textile products (textiles with electronic/conductive characteristic) which particularly exhibit electronic functions become frequent, and the request among users is increasing. Natural and synthetic fibers which have frequent usage in the present art do not have capacity which can show electrical conductivity. Thus, the development of said smart textile products is provided by means of inclusion of some conductive fibers to the textile structures and the usage of fibers shaped by means of nano technologic studies.
Celling is realized in the fabric structure by means of conductive fibers primarily in the usage of conductive fibers, and afterwards, the conductive fibers are included to the fabric structure during weaving or knitting processes in accordance with the data desired to be obtained. The usage of conductive fibers changes according to the dimensions of data desired to be obtained, and it affects the processability of textile product in an unfavorable manner. Besides, the weight of the textile structure is increased and problems occur in the usage of consumers in terms of ergonomics.
In electrical conductivity applications supported by means of nano-technologic studies, formation of electronic circuit systems in micro dimension is provided. In these applications, nano-dimensioned silver, copper and metal particles are used since the conductivities thereof are high. Various studies exist which are realized by means of the usage of nano- dimensioned silver. One of these is the product of Dyotec Company with name “Silver Conductive Adhesive”. In a similar manner, there are inks and adhesives developed by the Dupont Company. Despite all these applications, the usage of silver nano-particles on the textile surfaces may lead to increase of spread of silver nano-particles on the human body due to reasons like friction, etc. Moreover, it is known that the usage of silver particles which are 0.35 micron and smaller is harmful for human health. Because of all of these disadvantages, it has been decided that the usage of silver nano-particles on textiles is not suitable. Copper nano-particles increase the heavy metal proportion in waste water. Thus, the usage of copper nano-particles is not preferred in terms of environmental pollution in textile sector where non-interrupting and mass production is realized. In addition to these, chemical compliancy also exists among the approvals taken for the textile products. The presence of copper, silver, nickel, etc. in the fabric means that the chemical compliancy test is unsuccessful and is not approved. Moreover, against all these studies made, in nano technological applications, high conductivity data cannot be taken when compared with the conductive fiber usage.
As a result, because of all of the abovementioned problems, an improvement is required in the related technical field.
BRIEF DESCRIPTION OF THE INVENTION
The present invention relates to a printing paste which provides electrical conductivity to textile products, for eliminating the above mentioned disadvantages and for bringing new advantages to the related technical field.
An object of the present invention is to provide a printing paste which provides electrical conductivity characteristic to textile products without using conductive fiber or yarn.
Another object of the present invention is to provide a printing paste which does not have risk in terms of human health during usage and application and which provides electrical conductivity.
Another object of the present invention is to provide a printing paste which does not lead to chemical dirt and which does not give damage to the environment.
In order to realize the abovementioned objects and the objects which are to be deducted from the detailed description below, the present invention relates to a printing paste applied to textile products for providing electrical conductivity and formed by the basic components like sodium alginate, polyvinyl alcohol, urea and water. Accordingly, said printing paste comprises carbon black with dimensions between 0 and 50 microns and with usage proportion preferably between 2% and 20%. Thus, electrical conductivity can be obtained in textile products without needing conductive fiber or yarn usage and usage comfort is provided in the obtained products and environmental pollution is prevented.
In a possible embodiment of the present invention, the textile products where the printing paste is applied are woven, knitted or non-woven surfaces made of natural or synthetic fibers. Thus, production regarding a very wide area can be provided.
In a possible embodiment of the present invention, the printing paste is applied to said textile products preferably by means of silk mesh of 27.
The present invention moreover relates to a method for obtaining a printing paste applied to textile products for providing electrical conductivity. Accordingly, said method comprises the following steps: diluting pure sodium alginate with proportion of 1/3 and preparing the solution thereof such that the printing paste viscosity is preferably between 60 psi and 80 psi, mixing carbon black into the sodium alginate solution for duration of preferably between 15 minutes and 25 minutes.
DETAILED DESCRIPTION OF THE INVENTION
In this detailed description, the subject matter printing paste which provides electrical conductivity is explained with references to examples without forming any restrictive effect only in order to make the subject more understandable.
The subject matter printing paste has been developed for providing electrical conductivity to textile products made of natural and synthetic fibers (polyester, nylon 6.6, cotton, etc.) and woven, knitted or non-woven surface obtained from the mixtures thereof. The printing paste can be applied to textile products, which are in half-produced form or produced form, by means of rotational print or part print. In the printing paste, basically, water, urea, sodium alginate (NaAIg), polyvinyl alcohol and carbon black are used. The preferred usage amounts for the basic components provided in printing paste have been given in Table 1 below.
Figure imgf000004_0001
Figure imgf000005_0001
Table 1. The usage amounts of the printing paste components
In the preferred applications of the present invention, in addition to the above mentioned basic components, in the printing paste, there are also components which do not affect electrical conductivity in an unfavorable manner when they are removed from the printing paste. Said components are preferably polyurethane with usage proportion between 2% and 10%, ammonia, silver, copper, 2,2 oxydiethanol, poly-ammonium and dimethyl aldehyde oxy- ethylene.
Sodium alginate (NaAIg) included in the printing paste is a thickener and is used for bringing the printing paste to suitable viscosity value for printing. It is desired that the subject matter printing paste has viscosity between 60 psi and 80 psi for an efficient printing process. By taking this viscosity into consideration, the sodium alginate, obtained in a pure manner, has been preferably diluted with proportion of 1/3 and the solution has been prepared. The usage proportion of sodium alginate has been determined to be between 2% and 40%. In preparation of sodium alginate solution, tap water has been used with usage proportion preferably between 1% and 36% preferably at room conditions. For a homogeneous sodium alginate solution, the solution has been mixed in a homogenizer preferably for 2 hours. Polyvinyl alcohol and urea have been added into the solution. The usage proportions of polyvinyl alcohol and urea have been determined to be preferably between 1% and 2%.
The carbon black included in the printing paste is the carbon particles obtained by means of partial burning and/or thermal fragmenting from carbon hydrogen in gas or liquid form. The carbon black which has high electrical conductivity provides the obtained printing paste to have electrical conductivity characteristic. The carbon black added to the printing paste preferably has a dimension between 0 and 50 microns, and the usage proportion has been determined preferably between 2% and 20%. The carbon black has been added to the solution for duration preferably between 15 minutes and 25 minutes after preparing the sodium alginate solution. The carbon black is added to the solution gradually and thereby, the carbon black is distributed into the solution in a homogenous manner. In the opposite case, the carbon black may accumulate. This accumulation leads to the result that the electrical conductivity characteristic of the printing paste applied onto the textile product cannot be obtained as desired. The obtained printing paste is suitable both for rotational printing and part printing. To provide the printing processes and the transfer of the carbon black and sodium alginate to the textile product in a firm manner, preferably silk mesh of 27 is used. After the printing process is applied to the textile products, fixation process is realized. The fixation process is preferably realized within 2 minutes such that the feeding speed is 10 m/minutes at 165eC.
The protection scope of the present invention is set forth in the annexed claims and cannot be restricted to the illustrative disclosures given above, under the detailed description. It is because a person skilled in the relevant art can obviously produce similar embodiments under the light of the foregoing disclosures, without departing from the main principles of the present invention.
