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.
How much does a yard weigh? This is for accurate quotation. If you calculate the weight of one yard, you can know how much material is used for this yard of webbing. Is it single-sided or double-sided? Some are divided into single side and double side, so this should also be asked clearly. There are pictures for reference. This is to give us a visual judgment of what is, and give us a more accurate factor of quotation. How many are there? This is a matter of deciding whether to give customers a discount. If there is a large quantity, there must be a discount. Combine factors such as the wages of the factory, the master and the workers.
Hygiene: It is a natural fiber, and its main component is cellulose, with a small amount of waxy substances, nitrogen and pectin. After various inspections and practices, the pure cotton ribbon has no stimulation or negative effect when contacting with the skin. It is beneficial to the human body and has good sanitary performance after being worn for a long time. Heat resistance: the heat resistance is good. When the temperature is below 110 ℃, it will only cause water evaporation on the webbing and will not damage the fiber. Therefore, the use, washing, printing and dyeing of pure cotton webbing at room temperature have no impact on the webbing, which improves the washing and wear resistance of pure cotton edging webbing.
There are two primary methods for coloring, one is to apply it to a wide range of dyeing (conventional dyeing), and the first is to treat it in chemical dye solution. The other method is to use paint to make the paint into tiny insoluble colored particles to stick to the fabric (dyeing of fibrous material stock solution is not included). Acid dyes are mostly suitable for protein fiber, nylon fiber and silk. It is characterized by beautiful color, poor washing degree and excellent dry cleaning degree. It is widely used in natural dead dyeing.
For many printing, attention should be paid to printing when mass producing silk screen products, ribbon printing and ribbon printing. Screen printing is the basis of screen printing, and selecting appropriate screen is an indispensable link. As printing processing and screen printing have a very wide range of applications, there are many factors related to them. When selecting screen, different printing screens should be selected according to the specific situation and printing requirements. Generally, the following different perspectives can be considered when selecting screen. Screen shall be selected according to the type of substrate with binding ribbon printing and printing price. When selecting, it shall be selected and used according to fiber fabric, paper products, glass, ceramics, metal, plastic, wood products, electronic products, etc.
After yarn warp cylinder and weft winding form weft tube, special Shuttleless webbing wholesale It is inserted on the fixed gear seat of the knitting machine, and the weft tube rotates and moves along the 8-shaped track to draw the yarns to cross weave with each other. Usually, the number of spindles is even, the woven tape is tubular, the number of spindles is odd, and the woven tape is flat. Spindle weaving technology has been applied since old China. The number of spindles varies from 9 to 100 due to different equipment. The basic process of weaving is: bleaching and dyeing - weft rolling - weaving - off machine shearing - packaging. Since 1960, Guangdong special Shuttleless webbing Several technical innovations were carried out on the knitting machine, mainly including the enlargement of peach plate diameter, the installation of an automatic stop device for breaking rubber bands, and the replacement of iron ingots with nylon ingots. The improvement of these equipment has increased the vehicle speed to 160~190 rpm, doubled the stand rate and greatly improved the product quality.
