Direct dyes, suitable for cellulosic fabrics, have poor washing fastness and different light fastness, but the modified direct dyes will improve their washing color. Disperse dyes are suitable for viscose, acrylic, nylon, polyester, etc. The fastness to washing is different, polyester is better, and viscose is worse. Azo fuel (Naftol dye) is suitable for cellulosic fabrics. It has beautiful color and is more suitable for beautiful color and luster. Sulfide dyes are suitable, with dim color, mainly dark blue, black and brown, good light resistance and water washing resistance, and poor chlorine bleaching resistance. Long term storage of fabrics will damage fibers.
What does Dandong Guangwei Textile Weaving Group explain? Generally speaking, chemical fiber is added to cotton, a kind of polyester material. The invention of polyester and cotton has promoted the great progress of human textile, and it also has many advantages. Polyester cotton increases the tenacity of pure cotton yarn, which is not easy to break, and has elasticity! Some advantages of pure cotton, such as hygroscopicity and moisture retention, are mainly aimed at garment accessories. Some are not important to the fabric, and some are even shortcomings; The advantages of polyester are exactly what the ribbon yarn needs.
In the 1970s, due to the promotion of continuous ribbon dyeing and ironing machine, Changchun Shuttleless webbing manufactor From the traditional process of dyeing before weaving to the continuous process of weaving before dyeing, weaving before bleaching, ironing after treatment, the ribbon technology has entered the ranks of mechanized mass production. In the early 1980s, the industry introduced high-speed shuttleless loom, ironing machine, wrapping machine, warping machine, etc. from Switzerland, Italy and the Federal Republic of Germany, and the ribbon technology entered a new stage of development. The progress of webbing technology has brought about the upgrading of products. In 1980, Customized Shuttleless webbing manufactor The rubber ingot belt has the characteristics of soft, light, thin, firm, small elongation, small impact force, short and flat joints.
Computer drawing process. Many friends are particularly interested in computers. Xiao Bian has briefly introduced the textile technology of computer jacquard belts before, but many people are still interested in how to draw computer jacquard belts. Today, we will introduce its drawing method according to the drawing process of the ribbon. Single color change: change the color of the left or right mouse button in the picture according to the position within the parameter range, and change the color of a connected color block within the parameter range. The color changed depends on whether the left or right mouse button is pressed.
