Machine darning, also called seamless imitation darning, is a type of modern clothing darning technology. It uses sewing machines and special imitation darning technology to repair the damaged areas by imitating the color and texture of the fabric. No doily. Machine darning technology effectively complements manual darning technology, making the range of garments that can be darned wider and broader. The advantage is that the appearance is almost invisible, and the texture and color are consistent. The disadvantage is: not all clothes can be darned seamlessly.
Suitable fabric textures for machine darning: In machine darning, floral fabrics will have better results than large flower fabrics, and fabrics with compact patterns will have better results than sparse pattern fabrics. Fabrics with large patterns and sparse patterns are more suitable for embroidery. The patterned fabric adopts traceless imitation technology, which can achieve the effect of invisible traces. See picture book for details.
(1) Color matching and thread selection, select similar thread colors according to the hue of the fabric; pay attention to the cold and warm, clear and turbid tendencies of the colors.
(2), first use the first layer of thread color to pull up the hole, or wind it up by hand, and then tighten the support;
(3), press the horizontal opening, Weft direction. Requirements: Use a slightly lighter thread color to press the horizontal opening. It is required to leave no hair and make it clean and smooth. Those with different shades or hues should be pressed separately, that is, press deep for deep and shallow for shallow. The needle method is: use diagonally for lines. Flat sewing stitches, floral fabrics with obvious patterns, use loop stitching and free stitching methods (stitching methods in embroidery), strip and plaid fabrics are the same as twill;
(4), On the second layer, the flat stitches are moved in the direction of the longitude and latitude lines. The thread density can be arranged at a density of three to four rows of threads. The length should be based on the size of the damaged area, and the needle code size should be based on the size of the pattern.
(5) For the third layer, use well-matched threads and lay them every other stitch. The length should be 1/3 to 1/4 longer than the second layer and the width should be three to four columns wider than the second layer. The next level of analogy.
(6). Change colors back and forth, layer by layer, until there is no trace.
(7) It can also be done by stitching, when the thread color is not complicated and the hue is particularly close to the fabric to be patched.
(8), alternate needles, close needles, single lines or double lines, depending on the wiring situation.
The advantages of machine darning are: 1. The change from manual operation to machine operation improves work efficiency. 2. It breaks through the traditional darning method of weft and warp arrangement and proposes a new idea. 3. Large areas of damage and holes can be treated with good results and high efficiency.
The invention of machine darning is a supplement to the existing darning technology. It can solve the problem that traditional manual darning such as jeans and various floral clothes cannot achieve good results. It proposes a time-saving, labor-saving, A method to save costs and achieve traceless darning of fabrics.
In order to achieve the above purpose, machine darning adopts the following technical solutions: darning first involves color matching and thread selection. Observation cannot look at local colors in isolation, but must observe the details of color changes as a whole. Wiring must be based on wiring rules. One cannot be under direct sunlight, two cannot be under lights, and three cannot be under cloudy days, because under direct sunlight, the light source color accounts for a large proportion; under lights, the general color will tend to be the light source color of the light; cloudy environment The proportion of the color exceeds the natural color; the wiring should be done under natural indoor light. Look at the color of the fabric and choose threads that are the same or close to the color.
The color of the thread should be chosen based on the tendency of the fabric to be cold, warm, clear, or turbid. The basic colors are the three primary colors, namely red, yellow, and blue. The twelve colors seen from the color wheel all start from red. It is a mixture of , yellow and blue. However, no matter how much it changes, it tends to be bluish or reddish. Red represents warm colors and blue represents cold colors. Therefore, colors with varying degrees of red and yellow are generally warm or warm colors. , on the contrary, with varying degrees of cyan and blue, it is generally a cold color or a cold color, that is, achromatic black and white. It also has a tendency of cold and warm, such as black. Those that tend to be warm are brown and black, and those that tend to be cold are cyan and black (neutral) Black) white, colder is clear white, warmer is milky white.
Example: A pair of jeans, after frosting and washing, the dark one is blue, the middle one is blue-green, the light one may be light blue, it may be light grass green, it may also be light gray grass green, the tendency is If it's colder, it's light blue, if it's warmer it's light grass green, if it's greener it's light blue, if it's turbid it's light gray-green. You can't look at local colors in isolation, you have to observe them as a whole, and make the matching lines match the color of the entire pair of pants. color.
Find the required thread color, initially decide the order of threads, observe the holes and damage. The textile pattern of clothing is generally composed of two sets of yarns, longitude and weft. Multiple strands of yarn are vertically and closely intertwined with each other. Together, according to the thickness of the yarn and the texture, it can be divided into plain weave, twill weave, and satin weave. The warp runs along the length of the fabric, and the weft runs along the width of the fabric.
