What is the liquor ratio?

1. The bath ratio is the ratio of the weight of the fabric to the volume of the dye liquor during dip dyeing.

2. The bath ratio, also known as the liquid ratio, refers to the weight ratio of textiles to dye liquor.

OWF% means the weight of the fabric, that is, on weight of fabric. It is expressed when it is used for dyeing. It should be expressed as OWS% when printing, that is, on weight of solution.

3. Bath ratio, the ratio of the dyed material to the quality of the prepared dye solution when dyeing by dip or exhaustion.

It is omf (on mass of fabric), mass means "mass", here it can also be understood as "weight" but the description is more strict; it is often written like this when writing articles;

Strictly speaking, only the third statement is true.

Because weight is a measure of the force of an object under the action of universal gravitation, weight and mass are different, and the unit is Newton, which is a basic property of an object. The unit of mass is grams or kilograms. But in our daily life, we equate weight with mass.

Because in practical applications, the density of the dye liquor is often treated as water (the density is 1, that is, each kilogram of dye liquor is regarded as one liter).

Therefore, when measuring the weight of the dye solution, it is often directly measured by volume. So there is the first statement.

The ABCs of Liquor Ratios

A. The liquor ratio is divided into large and small: 1:20, 1:30 is a large liquor ratio, 1:3, 1:5 is a small liquor ratio.

Large liquor ratios are often used for laboratory samples. Small liquor ratio can be used in production, less liquid consumption and water saving. The specific liquor ratio is related to the equipment. How big is the liquor ratio of an overflow dyeing machine? The key is to make the fabric in a relaxed and unfolded state during the dyeing process, without scratching or blocking the cloth, and even dyeing to achieve Eco-friendly dyeing. Don't pursue a small bath ratio too much.

B. Calculate the bath ratio. For example, 100 kg of textiles use 1000 kg of dye liquor, and the bath ratio is 1:10. Sometimes the weight ratio of dye liquor, etc. to the textile is also used. For example, 1000 kg of dye liquor is used for 100 kg of textiles, and the liquor ratio is 10:1.

C. The liquor ratio of the dyed and large samples can be the same or different, and the key depends on the adjustment of the prescription.

Each dyeing factory attaches great importance to the dyeing formula, but it is often the first thought to adjust the formula when the color difference is encountered. In fact, the liquor ratio has a greater impact. At the end of most dyestuffs dyeing, the dyestuff will reach a concentration equilibrium in the water and on the fiber.

If the bath ratio is too large and the amount of water is too large, especially when dyeing with reactive dyes, direct dyes, etc., although the concentration of the residues in the dyeing bath does not change much, the total amount of dyes left in the water is large, resulting in less dye on the fabric. The color difference is big. Therefore, it is also very important to control the liquor ratio when continuing the production of the tank or the production of the order.

Since the actual inner diameter of each dyeing vat of the same model is different, the factory should measure the actual bath volume of each dyeing machine, and indicate the actual liquid volume in the vat on the liquid level scale. When dyeing, calculate the required amount of water according to the quality of the fabric and the bath ratio, and then inject the water to the specified amount (reserving the amount of dyeing liquid), and then enter the cloth for dyeing, so that the dyeing bath ratio can be effectively controlled.

Now there is a computer control device for liquid level, which can connect the water volume of each dyeing machine with the computer centralized control system.
