Latest News and Updates on Textile Auxiliaries and Dyes

When hot melt dyeing polyester-cotton blended fabrics, color-blocking dyes must also have the same properties as monochromatic dyes. The melting temperature and time should be adapted to the fixing properties of the dye to ensure the highest color yield. Each monochromatic dye has a specific hot-mel Read More

Disperse dyes have many varieties and wide chromatograms, and their sensitivities to pH are very different. Dyeing solutions with different pH values often lead to different dyeing results, which affect the depth of color, and even cause color change in serious cases. In weakly acidic medium (pH4.5～ Read More

Что такое объемная пряжаОбъемная пряжа по принципу производства аналогична композитной пряже POY-FDY, это пряжа, изготовленная путем смешивания волокон с высокой усадкой и обычных волокон в определенной пропорции. После того, как пряжа подвергается влажной термообработке, волокна с высокой усадкой д Read More

1. Disperse black:Disperse black is not a single black, but is generally made up of three disperse dyes (such as disperse violet, navy blue, orange, etc.). 2. Active black:The main component of reactive black is generally reactive 5# black, and the monochromatic 5# black is generally called navy blu Read More

1. Direct dyes:Direct dyes have relatively good heat-resistance stability. Direct dyes can be dissolved by adding soda ash and soft water. When mixing materials, first use cold soft water to make dyes into a slurry, then boil soft water and stir to dissolve, heat water to dilute, and add water to th Read More

1.1 Fixed-length titer unitDenier (D): Refers to the weight in grams of a 9000-meter-long fiber or yarn at a given moisture regain. For example: 1500D polyester raw silk means that the raw silk is measured 9000 meters, and its weight is 1500 grams. Others follow and so on.Special number (tex): also Read More

1) Twisting length of the bobbin: the length of the fiber or yarn wound on the bobbin after twisting. 2) Wool: The cord is fluffed due to yarn abrasion or raw silk. 3) Oil stained yarn: Yarn contaminated by oil. 4) Wrong denier silk: The same kind of raw silk in production, different deniers are not Read More

Los tejidos de punto son fáciles de estirar y deformar, fáciles de arrugar, fáciles de rizar, y el tamaño y la forma no son fáciles de estabilizar, etc., lo que requiere teñido y acabado, especialmente pretratamiento (también conocido como descrudado y blanqueado) y teñido. procedimientos. El tamaño de la tensión y la presión, es decir, cuanto mayor sea el grado de relajación de la tela, mejor. Read More

Los tejidos de nylon/algodón suelen teñirse mediante un sobreteñido en dos baños, es decir, teñir el nylon con tintes neutros, ácidos o dispersos y, a continuación, teñir el algodón con tintes reactivos a temperatura media. Para el teñido se utiliza el método de sobreteñido de dos baños. La ventaja es que el color (tono, tonalidad) de las fibras de nylon y algodón pueden compensarse entre sí durante el proceso de sobreteñido, y el color de la superficie de la tela es más fácil de ajustar y controlar; la desventaja es que el proceso lleva mucho tiempo, el rendimiento del procesamiento es bajo y el alto consumo de energía, la alta descarga de aguas residuales y los beneficios económicos deficientes.

AB yarn is a thread that is spun by mixing two different raw materials. Now it is generally called siro yarn, which is a yarn made by siro spinning technicians. Because there are two rovings, it is sometimes called AB yarn.(1) The simultaneous twisting of siro spinning makes the yarn have a special Read More

1. Dyeing spandex with disperse dyes, the optimum process conditions are: temperature 125℃, time 30～40min, pH value 5～6.2. The dyeing temperature should be controlled within the range of 120 to 130 °C. When the temperature is less than 120 °C, the color fastness is not enough, and it is easy to deco Read More
