Colors make our lives look good, add color to our lives, and make our world no longer monotonous.
Dyeing fabrics is a technical activity, and the color changes are endless, and the colors of different types of dyes are also different. In general, the dyeing of fabrics is divided into 5 kinds.
Natural color cloth is cloth that has not undergone any coloring treatment. Some fibers naturally have color, such as colored cotton, linen, sisal, etc. The requirement of these specific fabrics is that they are directly finished into fabrics that can be directly cut without coloring.
Because there will be some residual cotton in the natural cotton fabric or the cotton fabric used for high-end clothing is relatively high, it is necessary to bleach the cotton fabric to rinse the cotton off and make the color of the cotton fabric more uniform.
The bleaching mentioned in textiles is not bleaching like the bleaching agent used at home. Rather, it refers to a series of complicated processes. The woven cotton fabric is singed to remove excessive hairiness on the surface of the fabric, then the slurry on the fabric is washed, scoured to remove impurities, and finally bleached.
Of course, you can also directly bleach the yarn and then weave the fabric, so that the woven fabric is more smooth, and the fabric only needs desizing treatment after weaving.
After the fabric is woven, it is loosened from the loom, and after inspection, it can be sent to the dyeing factory for dyeing.
A piece of cloth can only be dyed with one color, and each color is derived from the three primary colors, so we can sometimes see that after black clothes are washed, the water is red, and some are blue.
The color of the front and back of the dyed cloth is the same. If it is a plain weave fabric, not only the color but also the texture is the same. There is no distinction between the front and the back.
If the fabric is only monochromatic, we will feel very monotonous, will it look better if there is a flower?
So we have printed cloth, the dyes of different fabrics are different, the printing method is naturally different. Reactive dyes can be used for cotton fabrics, disperse dyes are used for polyester fabrics (polyester), and pigment printing can be used on many fabrics and so on.
In the past two years, digital printing was born because of the development of technology. This printing method is more beautiful and lifelike, and it can print and dye photos, which is deeply loved by consumers.
Different dyes have different characteristics, so pay attention to distinguish them when washing, to avoid damage to the prints due to improper washing methods.
Yarn-dyed fabrics are woven after dyeing the yarn. This weaving method is also environmentally friendly and does not fade easily.
Fabrics dyed and woven with yarns are generally striped patterns, and can also be interspersed with some organizational changes to make yarn-dyed cut fabrics, yarn-dyed jacquard fabrics, etc., which add beauty to the yarn-dyed fabrics and make the stripes The pattern is no longer single.
Yarn-dyed fabrics are spun into yarns with dyed fibers and then woven. Such yarns have more than one color and have a special style. However, this dyeing method takes a long time and costs more.
In the past two years, the style of this color-woven fabric has been more popular with the public. Many sports and leisure clothing uses such fabrics, which are not easy to fade when washed, and are more convenient for care.
