1. The problem of sticky hands after printing glueAfter the printing paste is printed and dried, there is a sticky phenomenon, which becomes more serious with the increase of temperature.Reason: The main raw material of printing glue is acrylic resin, which is determined by the characteristics of th Read More
Agglomeration of DyesDue to the direct collision of dye molecules, larger dye aggregates (or dye associations) are aggregated. These larger dye aggregates are deposited on the fabric during the dyeing process, resulting in color stains.When dyeing: the free dye molecules will recrystallize during th Read More
Nylon is the trade name of synthetic polyamide fiber, commonly known as nylon. Its basic composition is aliphatic polyamide connected by amide bond -NHC0. The nylons commonly used in textile fabrics include nylon 6 and nylon 66. Nylon macromolecules are mainly composed of three parts, namely the hyd Read More
Unreasonable craftsmanship is easy to produce defects such as level dyeing difference, color flower, color willow, color difference, and poor fastness. 1. Control the initial dyeing temperature and heating rateNylon is a thermoplastic fiber, so the dyeing rate of the fiber has a great relationship w Read More
There are many varieties of reactive dyes, complete chromatography, simple process and relatively low price, so they are widely used. If color difference, color flower or cylinder difference occurs after dyeing, it is usually necessary to re-dye or repair the fabric. This not only affects the produc Read More
2. The influence of dyeing temperature on nylon dyeingTemperature is an important factor in controlling the dyeing of dyes. The temperature will affect the swelling degree of the fiber, the performance of the dye and the effect of the auxiliary agent. Nylon is a thermoplastic fiber, and the dyeing i Read More
Because the amino groups and carboxyl groups at both ends of the macromolecules of nylon fibers are sensitive to light, heat and oxygen, especially the amino groups, the number of groups will decrease during the process of oxidation and thermal cracking. Nylon fibers also turn yellow at the same tim Read More
1. The effect of pH value of dye solution on dyeingThe industry has always believed that the control of the pH value of nylon dyeing is the key to success or failure. After years of production accumulation, we found that if the buffer system auxiliaries and the selection of good leveling agents are Read More
According to foreign reports, Bangladesh's clothing exports to the United States may be hit as the United States imposes restrictions on related goods from China's Xinjiang region. This comes after the Bangladesh Garment Buyers Association (BGBA) issued a directive asking its members to be cautious Read More
Because reactive dyes have the advantages of excellent performance, complete chromatogram and bright color and light, they have been widely used in medium and dark colors for many years. Now some light colors and light colors include difficult-to-dye light colors such as light rice and light gray. , Read More
Fiber graphene inner warm fiber is a new intelligent multi-functional fiber material composed of biomass graphene and various fibers. It has low temperature and far-infrared functions that exceed the international advanced level, and integrates anti-static functions. Graphene inner warm fiber filame Read More
