What is Plant dyes and its application? Plant dyes refer to the use of natural flowers, grasses, trees, stems, leaves, fruits, seeds, barks, and roots to extract pigments as dyes.The technological utilization of vegetable dyes is the mainstream of ancient Chinese dyeing crafts. The amount of vegetab Read More

What is Printing paste and its application? Printing paste refers to a polymer compound that can be added to the printing paste to increase the thickness.Printing pasteIntroductionBefore the printing paste is added to the printing paste, it is generally a hydrophilic polymer thick colloidal solution Read More

Introduction to the principle and performance of new environmentally friendly additivesIn recent years, people's attention to environmental protection has led to the emergence of a series of environmentally friendly products. As an indispensable agent in textile processing, auxiliaries are no except Read More

La temperatura máxima de trabajo de este tipo de máquina de fermentación es de 130 ℃, la velocidad de calentamiento se puede ajustar y se utilizan dos tubos calefactores eléctricos como fuente de calor. Se pueden colocar hasta 12 copas de tinte, y el dispositivo de conexión mueve hacia arriba y hacia abajo el gancho con la muestra para completar el proceso de prueba. La capacidad máxima de la taza de tinte es de 300 ml y el peso de la tela determina la proporción de licor. Read More

El principio de teñido y el proceso de los colorantes reactivos. La molécula contiene grupos químicamente activos que pueden reaccionar con algodón, lana y otras fibras en una solución acuosa para formar un tinte co-enlazado. Tiene una alta solidez al lavado. Los colorantes reactivos se componen de colorantes parentales, grupos de enlace y grupos activos, de modo que pueden formar fuertes enlaces covalentes con fibras cuando se utilizan. Los colorantes reactivos tienen una serie de características incomparables con otros colorantes de fibras de celulosa, y han establecido su estatus como los principales colorantes para las fibras de celulosa. Se manifiestan de manera destacada en los siguientes cuatro aspectos: Read More

The active groups are monochloro-s-triazine and vinyl sulfone heterobi-reactive dyes. The commodity categories are named differently, mainly including M type, B type, RR type, BF type, BH type (partial), etc. The recommended dyeing temperature is 60～80℃. Due to the synergistic effect of two differen Read More

KN type mostly refers to the middle-temperature reactive dyes whose reactive groups are vinyl sulfones. The recommended dyeing temperature is 45～60℃, with moderate reactivity. This type of dye is basically dyed in the form of ß-hydroxyethyl sulfone sulfate. Because of its low directness to the fiber Read More

How to improve the color fastness of reactive dyesReactive dyes dye cellulose fibers to form chemical bonds with the fibers in the form of covalent bonds. Therefore, theoretically, the covalent bond between the dye and the fiber can give the dyed fabric excellent dye fastness. But in fact, its dyed Read More

The various properties that amino silicone oil imparts to fabrics, such as softness, smoothness, and fullness, are mostly caused by the amino groups in the polymer. The amino content can be expressed by the ammonia value, which refers to the number of milliliters of hydrochloric acid of 1 equivalent Read More

1. Pure cotton and blended knitted fabrics and woven fabrics are mainly soft hand feeling, and amino silicone oil with 0.6 ammonia value is mainly selected.2. Pure polyester fabrics are mainly smooth to the touch, and amino silicone oil with an ammonia value of 0.3 can be selected.3. Silk knitted fa Read More

Soaping fastness refers to the degree of fading of dyed fabrics after soaping in soap solution under specified conditions. It includes the original fading and white cloth staining. Original fading refers to the fading of printed and dyed fabrics before and after soaping. White cloth staining is a si Read More

The fading and discoloration of dyed fabrics is a relatively complicated process. Under the action of sunlight, the dye absorbs light energy and the molecule is in an excited state. It is unstable. The energy obtained must be released in different forms to become a stable state. One of the forms is Read More
