Heat migration fastness of disperse dyes:Migrating after dyeing means that after polyester is dyed with disperse dyes, when treated at high temperature (such as heat setting), disperse dyes can produce a kind of thermal migration due to the influence of additives. Thermal migration is a redistributi

Direct printing on polyester fabrics requires high temperature steaming after printing to avoid interpenetration of patterns and colors. Dyes with high sublimation fastness must be selected. In order to prevent patterns from fading under sunlight, light fastness is also very important. In order to r

The spandex cloth will turn yellow and the head will be big! Spandex is a commonly used fiber variety in our life. The most prominent feature is good elasticity, and it has the advantages of low fineness, large elastic modulus (elongation at break can reach 400%-800%) and small proportion. Spandex i

From the perspective of the molecular composition of polyester, it is composed of short aliphatic hydrocarbon chains, ester groups, benzene rings, and terminal alcohol hydroxyl groups. In addition to the existence of two terminal alcohol hydroxyl groups, there are no other polar groups in the polyes

Nylon/cotton fabrics are dyed with light color, and their nylon components are usually dyed with disperse dyes. The reason is: disperse dyes do not contain water-soluble groups, do not ionize in water, and do not carry active groups. Therefore, disperse dyes dye nylon, there is no ionic bond and cov

As a new printing method, digital inkjet printing is in line with the current personalized, fashionable and rapidly changing consumer trends, and has become the fastest growing field in the printing and dyeing industry in recent years. With the continuous decline in the cost of digital printing equi

According to the latest information, affected by the continuous raging epidemic, all parts of East China have recently upgraded prevention and control measures, announcing the temporary closure of expressway exits and service areas.Either "can't make an appointment with the driver", or "have an appo

(1) Physical properties of disperse dyes:Wetting, dispersibility, particle fineness, dispersion stability, etc. These properties will affect the preparation of the dye solution and are the main factors for the formation of dyeing spots.(2) High temperature dispersion stability of disperse dyes:Repre

1 What is the network degree of silkThe product of network processing is called network wire, also known as interlaced wire, which uses compressed air flow to spray, impact and collide the tow, so that the individual filaments in the tow are irregularly intertwined, forming a good cohesion. Performa

In the polyester dyeing process, the heating rate, the holding temperature and the pH value of the dyeing bath have a greater impact on the dyeing quality. Theoretically, under the condition of ensuring that the fabric does not appear colored, the shorter the dyeing process, the lower the dyeing cos

1 Appearance inspection The method is the same as the vat dye. 2 Inspection of dye components The method is the same as that of vat dyes. Note: The synthesis of the same disperse dye such as HGL blue is more expensive than the blending. 3 Diffusion test The method is the same as the vat dye. 4

2021 is a year of macro inflation and policy guidance. In the first half of the year, macro inflation will dominate, and the policy impact will be more prominent in the second half of the year. Under the background of the country’s 14th Five-Year "Carbon Peak-Carbon Neutrality", the energy consumpti
