Latest News and Updates on Textile Auxiliaries and Dyes

During the dyeing and finishing process of knitted fabrics, some unexpected quality defects often occur. If they cannot be dealt with in a timely and effective manner, they will affect the progress of the entire process and cause serious economic losses to production. Some young printing and dyeing

Direct dye dyeingDirect dyes can be used for dyeing various cotton and viscose products. When dyeing, first wet the fabric with water, add it to the dye solution, heat it to 95°C, add neutral salt to promote dyeing, and dye it for 60 minutes. Wash with water after dyeing, and if necessary, add color

Dissolving methods of seven commonly used dyes,such like vat dyes, direct dyes,

Continuous Dyeing is continuous dyeing. The tension of dyes is large. It is usually used for large -scale dyeing processing of fabrics, and labor productivity is high. The machine used by rolling dye is generally used for continuous rolling machines. The continuous rolling machine consists of some unit machines. It mainly includes unit devices such as rolling (dipping device), fixing, flat washing, drying, and steaming.

Medium temperature reactive dyesMedium-temperature reactive dye exhaust dyeing basically adopts conventional dyeing process. In fact, the dyeing properties of commonly used medium-temperature reactive dyes are not exactly the same, and there are three types.First typeThe performance characteristics

Corduroxy is cotton fabric with velvet and surface forming vertical velvet. The main raw materials are mainly cotton. Because the pills are like a stripe of lamp core, it is called a corduroy. Corduroxic ingredients are generally cotton, and there are fibrous blended or intertwined with fiber such a

When we buy clothes in the mall, we often see suede clothes. Many people don’t know what kind of fabric suede is. It feels like leather but not leather. Let’s take a detailed look at the advantages and disadvantages of suede fabric and how to clean suede as a reference: What kind of fabric is suede?

Overflow dyeing machines have a maximum nominal capacity, and this nominal capacity is not suitable for all fabrics. Therefore, during production, it is necessary to determine the actual capacity of the overflow dyeing machine according to different conditions such as the thickness and width of the fabric. For fabrics of the same width, the lighter and thinner they are, the smaller their capacity is. This is because if light and thin fabrics are fed according to the nominal capacity, the length of the fabric will inevitably be too long, and the cycle during dyeing will be long, which will easily cause the fabric to knot due to disorder in the dyeing room, causing fabric spots.

Inks play a vital role in various industries, from printing to textile and art. Acid dyes, with their vibrant and long-lasting colors, have become a popular choice for ink formulations. In this article, we will delve into the usage of acid dyes in ink and explore their benefits, applications, and impact on print quality.

Jacquard is a bump pattern composed of meridian and latitude lines. The difference between printing and jacquard After the fabric is woven, the flowers that are printed again can have multiple options. The lift fabric is woven when weaving, and the flower can not be selected after the shape of the c

1. The pH of the dye bath should be controlled at 5 to 6The pH of the dye bath should be controlled at 5 to 6, which must be adjusted with acetic acid. It is best to use 1 to 2 g/L ammonium acetate or sodium acetate as a buffer. Do not use the so-called "buffer" containing inorganic acids (S-1, C1-)

Speaking of desizing, we have to mention the three major sizing materials in the textile sizing industry: starch and derivatives, polyvinyl alcohol (PVA), and acrylic sizing. PVA has been gradually phased out due to environmental issues, and most of them are now used in combination with starch and acrylic slurry.

Four commonly used desizing methods: hot water desizing, alkali desizing, enzyme desizing, and oxidative desizing. Enzyme desizing and alkali desizing are currently used more frequently, and enzyme desizing (amylase) is mainly targeted at starch sizing. The desizing effect is generally evaluated by the desizing level. Among the three major slurries, acrylic slurry is easier to remove, while starch slurry and PVA both have simple and fast test methods (such as iodine/potassium iodide method.)

Insufficient desizing will affect the coloring rate of the dye during dyeing, or cause the fabric's feel to deteriorate.
