Latest News and Updates on Textile Auxiliaries and Dyes

FirstIn the color-fixing bath where salt and alkali coexist, the dye will be water-soluble due to the high concentration of electrolyte (salt, alkali), the greater salting-out effect, and the occurrence of the "elimination reaction" of the active group of ß-hydroxyethyl sulfone sulfate. The ability Read More

The original dyes are mixed, ground, and processed into commercial dyes with a certain amount of fillers and auxiliaries, and the process of standardizing the dyes is called dye commercialization. The commercial processing of dyestuffs is crucial to stabilizing the quality of finished dyestuffs, imp Read More

With the vigorous development of the national economy and the improvement of the national production level, consumers' recognition of the richness and vividness of textiles has continued to expand, and the demand has increased day by day. With the characteristics of high emission intensity, bright c Read More

Fluorescent Dyes: Dyes that strongly absorb and radiate fluorescence in the visible light range.The fluorescent reflectance of fluorescent dyes on fabrics depends on the intensity of the ultraviolet light source, the amount of fluorescent substances dyed on the fabrics and the fluorescent quantum ef Read More

Polyester, especially spandex-containing fabrics, generally have to be pre-formed by grey fabrics to ensure the smoothness of the fabric surface and the stability of specifications, and the setting conditions of grey fabrics (temperature, speed, air volume) will directly affect the subsequent dyeing Read More

Polyester is generally dyed with disperse dyes. Disperse dyes do not contain strong water-soluble groups and are dyed in a dispersed state during the dyeing process. A class of ionic dyes can be divided into three types according to dyeing temperature or sublimation fastness, S type, SE type , Type Read More

5. Цветной цветок (включая разницу в цвете, несоответствие цвета и т. д.)Окрашивание цветов является наиболее распространенной и распространенной проблемой качества в процессе окрашивания по следующим причинам:(1) Проблемы с рецептурой и эксплуатацией процесса: процесс составления рецептуры является Read More

Качество обработки (отбеливания) связано не только с качеством готового отбеленного изделия, но и непосредственно влияет на качество крашения, печати, отделки как полуфабриката. Некоторые эксперты говорят, что 70% проблем с качеством крашения и отделки изделий вызваны плохой предварительной обработк Read More

1. Alkali resistanceThe weak basic alkali agent basically did not cause damage to the acetate fiber, and the fiber weight loss rate was very small. After encountering strong alkali, especially diacetate fiber, it is prone to deacetylation, resulting in weight loss, strength and modulus decrease. The Read More

1. Acetate fiber not only has a certain degree of water absorption, but also has the performance of rapid removal after water absorption.2. The thermal stability of acetate fiber is good. The glass transition temperature of the fiber is about 185 ℃, and the melting termination temperature is about 3 Read More

1. Water inlet and liquid level control before the fabric is put into the tank During airflow dyeing, before the fabric enters the tank, the water inlet valve is first opened through the control system to enter the water. The amount of water entering is automatically controlled by the electrical con Read More

The dye bath for airflow dyeing is composed of the amount of liquid required for the fabric to absorb moisture and swell, and the amount of liquid that meets the needs of pipeline dye liquor circulation and dissolved dyeing materials at the same time. There is no need for water to drive the fabric t Read More
