Latest News and Updates on Textile Auxiliaries and Dyes

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 Read More

When dyeing nylon fiber, when the pH value of the dyeing solution is relatively high, the dye is rarely dyed; when the pH value of the dyeing solution drops to a certain value, the dye starts to be dyed, and soon reaches saturation. Continue to reduce the pH value of the dyeing night , The dye uptak Read More

Были приняты следующие меры против пиллинга:(1) Уменьшите молекулярную массу полиэстера, чтобы снизить сопротивление трению, сопротивление усталости при изгибе и прочность волокна, а также облегчить падение маленьких шариков, образованных волокном на поверхности ткани;(2) Измените форму секции волок Read More

1. Solubility High-quality reactive dyes have good water solubility in commercial applications. The solubility and the concentration of the dye solution are related to the selected bath ratio, the amount of electrolyte added, the dyeing temperature and the amount of urea and other factors. The react Read More

Para mejorar la solidez del color al frote de los textiles, primero debemos centrarnos en mejorar el grado de fijación del color del teñido textil; además, debemos lavar completamente el color flotante en la superficie textil; finalmente, la vellosidad en la superficie del hilo debe ser firme y no fácil de desprenderse.

Intermediate temperature reactive dyes have the problem of "unevenness", which is prone to dyeing defects such as color spots, chromatic aberrations, and stains. This is because there are two major defects in the dyeing performance of moderate temperature reactive dyes:①The stability of salt and alk Read More

Исследования показали, что, хотя прочность ковалентной связи, стабильность связи и адгезия, образованная реактивными красителями с разной химической структурой и целлюлозными волокнами, различаются, нет значительной разницы во влиянии на устойчивость окраски к влажному трению окрашенных тканей.Когда Read More

Good and poor color fastness directly affects the quality of textiles, as well as the health and safety of the human body. In the process of wearing products with poor color fastness, rain and sweat will cause the pigments on the fabric to fall off and fade. The dye molecules and heavy metal ions ma Read More

In September, textile and apparel exports stopped falling for four consecutive months and resumed growth; exports in the month increased by 2.66% year-on-year and 18.81% year-on-year, of which textile exports increased by 27.08% year-on-year, and clothing exports increased year-on-year 13.34%.From J Read More

Сушильная машина с сушильным цилиндром представляет собой контактную сушку, и контактная часть с сушильным цилиндром быстро нагревается и быстро сохнет, а также легко вызвать проблемы миграции. Следовательно, температура подающего цилиндра, с которым ткань сначала соприкасается, соответственно ниже, Read More

Fluorescent dye is a dye that can strongly absorb in the visible light range and can radiate fluorescence. From the 20th century to the present, organic fluorescent dyes have been widely used in various industries such as textiles, plastic dyeing, and printing pigments. They can also be used in mari Read More
