Latest News and Updates on Textile Auxiliaries and Dyes

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

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

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

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

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

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

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

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

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. ,

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

According to the latest "China Keqiao Textile Index" released by the Construction Management Committee of China Textile City, recently, the largest professional fabric market in Asia - innovative fabrics, has heated up transactions.China Textile City is located in Keqiao District, Shaoxing City, Zhe

Due to the problems of thick details and uneven twist on the yarn, there will be some fragments with less strength on the yarn, which will cause the hidden danger of spun yarn breakage, which is called "the weak loop of yarn strength". The existence of the yarn strength and weak loop is one of the k
