1. Reactive dye mass fractionThe polyester-cotton fabrics were dyed with disperse golden yellow/reactive yellow, disperse blue/reactive blue and disperse red/reactive red respectively. Disperse dye 1% (omf), NaCl 30g/L, 130℃ for 40min, the effect of neutral fixation reactive dye mass fraction on K/S Read More

One-bath dyeing and anti-ultraviolet finishing of polyester-cotton fabrics with disperse dyes/reactive dyes and neutral fixation/ultraviolet absorbers. The effects of dyes, sodium chloride, benzyl alcohol and UV absorbers, as well as temperature and time on the K/S value and UV resistance of polyest Read More

Los pasos clave para identificar los tipos de colorantes en las fibras de celulosa son el muestreo y el pretratamiento de la muestra. Al tomar la muestra se debe tomar la parte del mismo colorante. Si la muestra contiene varios tonos, se debe tomar cada tono. Si se requiere identificación de fibra, el tipo de fibra debe confirmarse de acuerdo con el estándar FZ/TO1057. Si hay impurezas, grasa y lodos en la muestra que afectan el experimento, debe tratarse con un detergente en agua caliente a 60-70 ℃ durante 15 minutos, lavarse y secarse. Si se sabe que la muestra está acabada con resina, utilice los siguientes métodos respectivamente. Read More

Con el alto grado de las telas textiles de poliéster humano, especialmente el crecimiento de las telas deportivas y las telas para exteriores, la solidez al lavado de los colorantes dispersos convencionales es pobre, especialmente la mala migración térmica durante el termofijado después del procesamiento, lo que hace que los colorantes dispersos de alta solidez al lavado se hayan vuelto un punto de crecimiento de la industria y un punto caliente en la industria.

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

01 метод очистки А. Очистка холодной водой В хлопчатобумажных и смешанных переплетенных тканях после окрашивания хлопкового компонента прямыми красителями или реактивными красителями появляется плавающий цвет или тусклый цвет, обычно продолжают стирку или добавляют вспомогательную стирку 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
