Description

Innovation in Digital Sublimation Transfer Papers Technical Field
The invention relates to digital sublimation transfer paper, which is specially produced for the printing of polyester-containing fabrics in different colours and shapes by heat transfer method using digital printing machines.
Prior Art
Paper is a thin material that is mostly used in writing processes, can be printed or drawn, or used for packaging. It is obtained as a result of pressing cellulose pulp obtained from damp wood fibres or weeds' cloths in flexible boards after pressing.
Two basic raw materials are used in paper production. The first one is pulp, and the second one is wastepaper. The share of wastepaper in total raw material production and consumption is increasing. Production and consumption of wastepaper as raw materials show a faster development compared to pulp. According to the annual statistics report of the forest products prepared in 2017 (FAO Forest Products Annual Statistics Report, 2017), wastepaper production, which was 217.71 million tons in 2012, increased to 231.44 million tons in 2017. Wastepaper consumption shows a similar development. Consumption, which was 217.06 million tons in 2012, was 231.41 million tons in 2017. It is seen that all collected wastepaper are recycled and used. While the share of wastepaper in consumption of the two raw materials was 55.9 percent in 2012, it increased to 56.2 percent in 2017. The production and consumption of pulp have also increased gradually over the years. The production, which was 171.46 million tons izn 2012, reached 181.44 million tons in 2017. As the world's paper raw materials, wastepaper is used at a rate of 70-75 percent, and cellulose at a rate of 25-30 percent. As such, an effective wastepaper management has become critical for the paper industry. All paper producing countries aim to increase wastepaper collection and use rates and to increase the quality of the collected paper. Wastepaper management is even more important for Turkey, which is a country totally dependent on imports of cellulose.
Recycled fibres are classified according to their source of collection. The most valuable recycled fibre source is unprinted trimmings. This is followed by office papers, newspaper papers, corrugated cardboards. Since the collected papers without a classification are suitable to produce a limited variety of paper, they are considered as the lowest source of raw materials in terms of recycling. As a matter of fact, the quality of the paper used in the sublimation transfer process does not have a significant effect and importance on the transfer process.
The wastepaper industry has raw material sources that are not dependent on forest resources. In this respect, limited forest resources are used more rationally for the paper and forest products industry. Waste pulp has a separate market. Therefore, the fibres recovered according to the fluctuations that may occur in the wood pulp market provide an alternative and safe source. The recycling process of wastepaper is easier than the production of wood pulp, and it is generally cheaper than the wood pulp with the same properties since less chemicals and energy are consumed.
Establishment and operation of wastepaper recycling facilities can be done with less cost, can be operated with lower energy usage and operating costs, and production can be sustained with less damage to the environment. Solid waste problems of municipalities can be significantly reduced by utilizing wastepaper and a significant added value is added to the national economy. Thus, as an alternative to the plants producing paper pulp from wood that requires very high investment and operating costs, some paper-cardboard products can be manufactured economically from recycled cellulose fibres.
In the prior art, paper recycled from waste is not used in sublimation transfer printing. The paper is printed with specially produced sublimation transfer inks in digital printing machines and pressed on the fabric with heat presses to transfer the ink and the paint on the paper evaporates with heat and adheres to the fabric containing polyester. Thus, the desired pattern is transferred onto the fabric. This technique applied with digital machines has developed in our country in recent years. The papers used for this job are produced for other purposes in our country and their colour efficiency is well below the desired level. In the prior art, either white paper or high-grade paper is used as transfer paper. In the transfer process of the image to be printed on the fabric, due to the chemical coating on the transfer paper, the quality of the paper does not change the quality of the final product / fabric printing. Transfer paper only takes over the task of moving the image. It is the layer that absorbs the image, not the transfer paper, but consists of a chemical mixture on the said transfer paper. Recycled paper produced from wastepaper is not used as transfer paper in the prior art.
Purpose of the Invention The object of the invention is to provide the use of recycled paper produced from wastepaper as digital sublimation transfer paper.
Another object of the invention is to prevent the use of pulp in digital sublimation transfer paper.
Another object of the invention is to obtain a new ecological and environmentally friendly transfer paper.
Transfer paper developed to achieve the said objectives is produced from recycled paper and contains a chemical mixture.

The main parts expressed in the figures are given below as numbers and names.
(1) Transfer paper (2) Chemical mixture Detailed Description of the Invention
The invention is the sublimation transfer paper, which is used to transfer the patterns in different colours and shapes to the fabric and characterized by containing a chemical mixture (2) that provides the ink, which is used for transferring the colour and pattern, to be confined on the upper surface and dry by preventing it to be absorbed into the interior of the paper in order to transfer more vivid and high quality colours on the fabric, and being transfer paper (1) recycled from waste.
The invention relates to digital sublimation transfer papers (1), which are specially produced for the printing of patterns in different colours and shapes on polyester-containing fabrics using digital printing machines by heat transfer method.
A chemical mixture (2) applied on the sublimation transfer papers (1) prevents the sublimation ink from being absorbed in the interior of the sublimation transfer paper (1). At the same time, it ensures that the forms that make up the image are separated with clear lines and a clear image is obtained on the transfer paper (1). The solution, namely the chemical mixture (2), prevents the printing transfer paper ( 1 ) from absorbing the paint, as well as drying the paint on the upper surface of said transfer paper (1).
The amount of the chemical mixture (2) applied to the transfer paper (1) varies in the range of 2-10 g/m2 dry matter. Six different chemical mixtures (2) that provide these features are used. After the mentioned chemical mixtures (2) are prepared, they are applied on the transfer paper (1).
Chemical mixtures (2) applied on transfer paper (1) are as follows.
Chemical mixture 1 - 70-80% water
- 10-15% Polyvinyl alcohol (Celanese Celvol E 4/98)
- 2-3% Carboxyl methyl cellulose (Aciselsan Ty-30)
- 3-4% Glycerin
- 4-5% Ammonium polyacrylate (Lambretti S.P.A. Reotan LA M) Chemical mixture 2
- 50-70% water
- 5-15% Amorphous Silicon Dioxide
- 15-30% Ammonium polyacrylate (Lambretti S.P.A. Reotan LA M) Chemical mixture 3
65-80% water
35-20% ammonium polyacrylate (Lambretti S.P.A. Reotan LA M)
Chemical mixture 4 60-85% water 15-40% sodium poly aery late (Rodex Rodexperse N 201)
Chemical mixture 5 50-70% water
25-35% sodium polyacrylate (Rodex Rodexperse N 201)
5-15% ammonium polyacrylate (Lambretti S.P.A. Reotan LA M) Chemical Mix 6:
75% water
25% polyvinyl alcohol (Celanese Celvol E 4/98)
When any of the above-mentioned chemical mixtures (2) is applied onto the said transfer paper (1), the expected properties are provided from the digital sublimation paper (1).
The chemical mixtures (2) are dyed on the transfer paper in the plastering machine at a speed of 30 to 100 metres/minute and dried in the ovens that blow 60 to 100 °C of hot air for 10 to 20 seconds. Then they are wound as 5000 to 6000-metre coils. Then, they are wrapped in rolls of 80 to 250 metres and become final products. The invention relates to transfer papers (1) on which the prepared chemical mixtures (2) are applied. As the transfer paper (1), recycled paper produced from wastepaper is used. The transfer paper (1) has no other function after it assumes the task of transferring the image on it. Since the image is absorbed by the chemical mixtures (2) applied on the transfer paper (1), the paper used is used only as an intermediary. For this reason, recycled paper from waste is preferred instead of using quality paper.
The use of recycled paper in the sublimation transfer process is only possible with chemical mixtures (2). Thanks to the chemical mixtures (2) of the present invention, the image to be transferred is ensured to be absorbed at an optimum level before reaching recycled paper.
