Los Colorantes reactivos de temperatura intermedia tienen el problema de la "desigualdad", que es propenso a defectos de teñido como manchas de color, aberraciones cromáticas y manchas. Esto se debe a que existen dos defectos principales en el rendimiento de teñido de los Colorantes reactivos a temperatura moderada: Read More
On the basis of pre-processing of knitted fabric printing semi-products, in order to meet the printing requirements and ensure the quality of products and the smooth progress of production, according to the summary of production practice, the following work should be generally carried out. ⑴ prepres Read More
(1) Recovery of fiber deformation under moist heat state. When cotton knitted fabric is washed in a relaxed state, water molecules can destroy the newly generated hydrogen bonds, relax the internal stress, and shrink the elongation part by shrinking. ⑵ recovery of knitted fabric deformation. When th Read More
Los rayos ultravioleta apropiados son beneficiosos para la salud humana, pueden promover la síntesis de vitamina D, reducir la aparición de esterilización y tener un cierto efecto de desinfección y esterilización. Read More
GuíaLos rayos ultravioleta excesivos causarán daños graves en la piel. Cuanto más corta sea la longitud de onda de los rayos ultravioleta, mayor será el daño a la piel humana. Los rayos ultravioleta de onda corta pueden pasar a través del cuero, y las ondas media pueden ingresar al cuero. Read More
Before the cold rolling pile, the treatment should be in production:① Use a multi -rolling rolling method to ensure that the liquid penetration is evenly consistent. Generally, two grooves are used, and the front grooves are rolled with three rollers, and the rear grooves are used with two rollers.② Read More
In the processing process in front of the cold rolling pile, its stacking time is a non -processing process in front of the cold rolling pile. The stacking time is a very important process parameter. , 12h, 16H, 24H, etc. As for why this stacking time is used, few people pay attention and think abou Read More
En los últimos años, debido a la gran cantidad de compuestos que contienen halógenos, como el freón, está varado sobre la tierra y se descompone por los rayos ultravioleta en halógeno activo. Read More
Los rayos ultravioleta se refieren al término general de la longitud de onda del espectro electromagnético de 10 nm a 400 nm, y no puede causar la visión de las personas. Read More
The structure of knitted fabrics is loose and easy to deform. During the printing production process, it is easy to lengthen in the warp direction and narrow in the weft direction. Fabric deformation will bring a series of problems in printing, resulting in weft skew. Wrinkles and printing defects i Read More
① There are many kinds of processing, because dyes are fine chemical products, generally the production tonnage is not large, there are many varieties, and the processing methods are different, so the process and equipment are quite complicated; ② The dye factory needs to adjust the dosage form or c Read More
There are many reasons for the color difference between samples, and the main reasons are the following aspects.① Be strict and accurate when playing samples. Sample samples are the key to directly affecting the large -scale production of the workshop. We must fully understand its importance and pay Read More
