Guys, now let’s solve a little riddle:
With legs and no arms,
With sides, but without ribs,
With a seat, but without a belly,
With a back, but without a head.
Under the roof – four legs,
And on the roof there is soup and spoons.
If you’re tired of playing,
Then you lie down on…
Everyone will notice me in the room,
And having opened me, he will meet winter and summer.
I’m comfortable, very soft,
It’s not difficult for you to guess, –

| And carefully glued it to the walls of our boxed room.|
Frames were made of white paper around the windows. Everything is like people)
And we made the door yellow with curly green tabs. In general, our entire room will be in yellow-green tones.
The room is ready. We begin manufacturing furniture and interior items. Let’s start with the sofa. Let’s take a tea bag, colored paper, scissors and a lid from a box that has already turned into a room.
We cover the box with paper, and cut out the back and sides of the sofa from the lid.
We also cover the sides and back with colored paper and glue them to the sofa. Ready! You can sleep)
A floor lamp is provided as lighting in our cardboard room. Let’s make it from a toilet paper roll.
The floor lamp will look like a lampshade on a leg, remember, these used to be very popular. Cut out the sleeve like this. There is a lampshade on top, a stand on the bottom, and a leg between them.
We paint the inside of the lampshade with yellow paint, and the stand with green paint.
We cover the outside of the lampshade with yellow corrugated cardboard, and the leg and stand with green.
This is what the floor lamp looks like from behind. Now it won’t be dark)
Let’s turn a box of vitamins into a closet.
Just cover it with colored paper. The closet is ready! Now there will be somewhere to put things.
And we’ll turn these matchboxes and a piece of cardboard into a desk.
Glue the boxes together, 4 pieces at a time. And cover them with colored paper.
We decorate the drawers, glue colored paper and half beads, which act as handles on the drawers, you can make them from something else. We decorate a tabletop made of durable cardboard with colored paper.
Glue the tabletop in place.
We make the chair using the same principle. We take two matchboxes and a piece of thick cardboard.
We cover everything with colored paper and connect it into a single whole. Ready! Have a seat)
Here it is, all our designer yellow-green handmade furniture.
Let’s try to put the furniture in its place. View from above.
View from the door.
View from the windows.
And everything would be very good, but there are not enough decorative things. Let’s do interior design. We found these cute pictures with the cat Basik. What you need)
We cut out frames for our paintings from yellow corrugated cardboard.
We glue a large picture in the area of the door.
We “hang” a couple of small paintings on the other wall. And we have another one located near the sofa.
Next up is textiles. We decided to put beautiful pillows on the sofa. How to make them? First, cut out square blanks from felt.
Yes, and we also placed an ottoman on the floor next to the sofa. Finally, we found a use for our green pompom, which we made with our own hands a long time ago)
And they hung curtains on the windows for comfort. They were made from old tulle that had served its purpose. Felt strips were sewn along the top of the curtains and then simply glued to the wall above the windows. The room immediately felt cozy)
This is what the room looks like from above now.
Let’s take a look from here too. Beauty, isn’t it? Would you like to live in such a room? We wouldn’t refuse)
That’s the whole master class. Try to create something similar in your free time. This is truly a very exciting activity.
That’s all for today! Come visit again, you are always welcome here)

REVIEW OF MODERN IMAGE APPLICATION TECHNOLOGIES
FOR FABRIC MATERIALS FROM NATURAL AND SYNTHETIC POLYMERS
Key words: glue, paints, printing, stencil, transfer, thermal transfer, sublimation, fabric, material.
Modern technologies for applying images to fabric materials made from natural and synthetic polymers have been studied. It was revealed that the printing technology is selected depending on the chemical composition of the fabric fibers, the color of the material, the number of products and the color of the image.
Keywords: glue, paint, print, stencil, transfer, thermal transfer, sublimation, fabric, material.
Investigated by modern technology, the decoration of textile materials from natural and synthetic polymers. Revealed that the printing technology is selected depending on the chemical composition of fabrics, colors, material, number of products and color images.
All existing technologies for applying images to fabric are based on the interaction of paint and fabric fibers. There are several types of inks used for printing on fabric: plastisol, water-based, solvent and
Plastisol (polyvinyl chloride-based) paints adhere well to fabric, enveloping its fibers without coloring them, but providing mechanical adhesion. Therefore, they are also well suited for printing on thick, water-repellent nylon fabrics that cannot be printed with other inks. Plastisols are very elastic, they can be easily colored with pigments and foamed by adding certain reagents. These paints are very durable. Plastisol paints can be foaming, phosphorescent, with a “metallic” effect, with glitter, and elastic. Also included in the category of plastisols is a special adhesive for foiling products.
The second group of inks are water-based, which can be used to print on natural and many
synthetic fabrics. Water-based paints
have a significant drawback: they are lighter
are washed out. However, in certain cases, their choice is completely justified: they are cheaper than plastisol ones, and justify themselves if it is necessary to produce a large circulation of products that will be used once or twice, for example, for
holding any promotion. Water-based paints can be process, fluorescent, or metallized. To dry them, high-temperature drying is required, which somewhat limits the range
The next type of ink is solvent ink, intended for printing on synthetics.
Also used for printing
sublimation inks, which are used to create transfers that can be transferred to light-colored synthetic fabrics. The drawings are very durable, highly lineature, and the quality of the prints is comparable to offset ones. Sublimation transfers are well suited for small runs .
Today, many different technologies have been developed for applying colorful images to fabric, which are divided into two groups: direct and indirect printing methods. All direct printing technologies involve applying an image directly to fabric, for example, using silk-screen printing or drawing individual copyrighted copies by an artist using a brush or screen printing with a pad. Indirect printing methods involve applying an application to a product through an intermediate medium, this is how all types of transfer printing are performed. Each method has its own advantages and disadvantages.
One of the oldest methods of direct printing on fabric is drawing an image using a brush or screen printing with a pad. The advantage of this technology is that it is suitable for all types of fabrics. For this purpose, special paints have been developed that can be used for individual decorative purposes and on an industrial scale. Almost all paints for decorative painting on fabric are suitable for cotton, and special paints have been developed for silk and linen. Paints for decorative painting on fabric have different consistencies, which allows you to imitate various artistic painting techniques. For silk, liquid paints are used, which are applied in a thin layer, and for dense fabrics, thick paste paints can also be used. Fabrics treated with special compounds tend to resist the application of such paint, like many synthetic ones [2-3].
Silk-screen printing technology has been known for a long time; its prototype was screen printing, invented in Ancient China. The principle of silk-screen printing is to apply viscous paint to a product by pressing it through a fine sieve stencil using a special elastic knife – a squeegee. Thanks to the ability of screen printing to produce a layer on the print whose thickness is many times greater than with other technology, images are bright and saturated, including on materials with a pronounced texture.
This method can be printed on any textile materials, so it is one of the most common ways to print small images on fabric. The ability to widely use special effects – glitter (spangles), light reflection, thermal rise, three-dimensional printing, imitation velvet or rubber when printing on finished garments makes modern silk-screen printing a leader among technologies for creative solutions. This technology makes it possible to achieve excellent abrasion resistance, largely due to the ability to obtain a thick paint layer from normal 8-10 microns to 500 or more color brightness. The advantages of this method include the ability to print on almost any material.
Direct printing methods also include the technology of printing on fabric with vinyl films, in which the image is applied using special multi-colored films. With this printing technology, the applied image is cut out from a single-color film on a cutting plotter and glued to the fabric using a press. The image applied using vinyl films is resistant to abrasion, the film does not wear off or fade, and is only resistant to aggressive environments (for example, it dissolves in alcohol). The disadvantage is the fact that it is impossible to apply a full-color image with vinyl films, since this technology is intended for applying 1-3 color images. Another limitation of the technology is small parts. Some design elements are technically impossible to manufacture, such as a 1mm square.
One of the new and promising direct printing technologies is inkjet printing directly onto the fabric, after which the image is fixed for one and a half minutes in a heat press. Printing occurs with water-based pigment inks. The image is printed with high photographic resolution and allows you to work out even the smallest details. This technology allows you to achieve good quality and durability when printing on white and light-colored materials, since the ink penetrates into the structure of the fabric,
When printing on dark materials, the process changes slightly. First, white paint is applied to the fabric, which hardens into a thin layer similar to rubber, after which a color image is applied to the white “backing”. Due to the specifics of this technology, during the first wash, 10-15% of the color is removed from dark T-shirts, but even so, the durability indicators of direct printing technology are second only to screen printing. Another distinctive feature of this technology is the wide range of printed materials, this method allows you to print on any fabric that can withstand heat curing at a temperature of 150°C, namely: colored and dyed cotton T-shirts, linen, jute, denim, tarpaulin,
canvas, chintz. The exception is natural silk, due to its low adhesion properties.
Transfer printing on fabrics refers to indirect screen printing methods. This method involves transferring paint to the product through an intermediate medium, which is paper. Thus, to obtain a design on fabric, you need to print it on paper, and then use a heat press to transfer it. Thermoplastic (or adhesive) transfer uses silicone paper as the printing substrate, and the image is formed from several layers, and the printing is done in a reverse (mirror) image. An essential feature of this method is the application of the last layer of thermoplastic material – glue. When transferred under the influence of high temperature, the glue softens and penetrates the structure of the fabric, and when cooled, it hardens again and the entire transfer is firmly glued (fused) into the substrate. After this, the silicone paper is easily separated, as a result of which the design is transferred to the fabric.
The thermoplastic transfer method can be used for most types of heat-resistant fabrics, and their chemical composition does not matter, since only the adhesive is in contact with the substrate. The color of the fabric can be either light or dark, since when printing transfers, mainly opaque inks are used, and if necessary, a white backing can also be applied.
Transfer printing is an alternative method of applying an image to fabric. Transfer printing, unlike direct printing, has no restrictions on the number of colors used in the image, allows you to achieve accurate color registration, and also allows you to obtain raster images of good quality, since the paper on which transfers are printed, unlike fabric, is smooth and almost non-absorbent. The advantage of transfer printing is the fact that if a defect occurs during printing, only a sheet of paper will be damaged, and not an expensive textile product. Transfers can be printed in one edition, which can subsequently be transferred to various products made from fabrics of different composition.
The variety of fabrics that can be printed with this method also determines one feature that should be kept in mind:
image durability on different materials may vary .
The advantages of thermal transfer printing include the relatively high resistance of the pattern to friction and the fact that
The image can withstand machine washing up to 80°C. Another advantage is the ability to produce an image in a single copy with high quality of application and detail . It should be noted that due to the variety of fabrics used for printing, the images obtained on them may have different properties,
first of all, durability. Therefore, it is recommended that manufacturers always carry out testing before using a new type of fabric. This applies to all transfer printing technologies.
Sublimation transfer printing technology, unlike thermoplastic, does not involve transferring the entire ink layer from paper to fabric. It is based on the property of some dyes to transform into a gaseous state (sublimate) under the influence of temperature. Printing is done on special paper. During the transfer process, under the influence of high temperature, dyes diffuse into the fabric structure. Dye molecules form a chemical bond with certain active groups of fiber molecules, so this method is applicable only for synthetic or mixed fabrics. There is no paint layer in the traditional sense, therefore, using this technology, it is possible to obtain an image only on white or light-colored fabric.
Sublimation heat transfer printing is very important in decorating synthetic fabrics. This method is used in the manufacture of flags, sportswear, umbrellas and many other products. Compared to thermoplastic transfer and direct textile printing, it has several advantages. First of all, it is high chemical, thermal and radiation resistance. Sublimation transfer can be carried out on most synthetic fabrics or mixed ones with a synthetic content of at least 60%.
Printing with sublimation dyes on paper for subsequent transfer can be done in various ways: offset, flexography or on a printer, but screen printing is most widespread. This is due, first of all, to the fact that silk-screen printing allows you to apply the thickest layer of paint, resulting in high brightness and color saturation after transfer. The choice of screen printing is often also determined by the fact that the equipment used imposes virtually no restrictions on the print format, which is especially important in the manufacture of flags and clothing.
Printing of sublimation transfers can be done on any type of screen printing machines: manual, semi-automatic, automatic.
Thermal transfer requires the use of presses with a uniform distribution of temperature and pressure over the plate area, since otherwise the transfer of dyes will be uneven and the image will receive unequal saturation in different places. Abroad, callanders are often used instead of a heat press. It is recommended to dry printed sheets of paper in a hot air oven or at room temperature. Once drying is complete, the transfers are ready for transfer. It is not recommended to store finished transfers for a long time, since sublimation dyes tend to migrate, which results in loss of image clarity.
Transfer conditions are different for each type of fabric. For example, for polyester, which is used most often, the transfer is carried out at 200-220 ° C for 40 seconds. For other materials, it is recommended to select the temperature and time experimentally.
Thus, technologies for applying images to modern fabric materials made from natural and synthetic polymers have been studied. The presented printing technologies are selected depending on the chemical composition of the fabric fibers, the color of the material, the number of products and the color of the image.
