Distinct batches always have a different hue when the same process prescription, process dyeing ingredients, and other variables are used. Poor color reproducibility of colored yarn is primarily due to the inconsistency of dyes used in various dyeing batches. All process variables must be under control for yarn dyeing to be reproducible. This article describes 12 common factors that affect the reproducibility of yarn dyeing. It is very beneficial for textile enterprises or dyeing factories to control product quality. ​What is yarn dyeing reproducibility In intermittent dyeing, the same colored object (yarn) is dyed with the same dyeing ingredient, recipe, and technique, however there is a phenomena of color variation between dyed products in different dyeing batches. This is referred to as poor reproducibility (ie cylinder difference). Causes of poor yarn dyeing repeatabilit The reason for poor color reproducibility is complex. Roughly speaking, yarn, dyeing and chemical materials, pro

  A cone dyeing machine is also called a package dyeing machine, a  bobbin yarn dyeing machine  or a cheese dyeing machine. When we introduced  package dyeing  before, we mentioned that there was a major flaw when dyeing with a cone dyeing machine. That is, the color difference between the inside and outside of the cheese is relatively large. In this article, we will analyze the causes and prevention methods of the color difference between the inner and outer layers of the cheese yarn. Manifestations of color difference There are two cases of color difference of cone dyeing. The middle yarn and inner yarn have different shades of color. The different shades of color between inner yarn and outer yarn Discrimination method Generally speaking, there are two ways to judge the color difference of the cone dyeing: Visually assess the degree of color difference between the inner and outer layers. Use a small knitting machine to knit the yarn into tubular fabric. That is, use inner, middle and

​ HTHP dyeing machine is the abbreviation of high temperature and high pressure dyeing machine. This type of dyeing machine is generally used to dye chemical fiber grey fabrics and yarn products. And it has the characteristics of high color fastness and uniform dyeing. However, the dyeing process requires high temperature and high pressure steam, and the dyeing machine is subjected to high temperature and high pressure, which is dangerous. Cotton fabrics are generally dyed at normal temperature and pressure. Different types of HTHP dyeing machine HTHP beam dyeing machine ​The knitted fabric is wound on a hollow reel warp beam with small holes on the surface, sent into a horizontal cylindrical stainless steel shell, sealed and pressure-dyed, and then processed. The dye liquor is transported by a centrifugal pump and circulates from the inside to the outside or from the outside to the inside to the fabric layer through the warp beam. This type of dyeing machine may create color differenc

Textile dyeing machine can be individed into fiber, yarn, fabric and garment dyeing machine.  The previous post  has introduced the two types of textile dyeing machine. This blog will tell you about the other. Fabric Definition of fabric ​Fabrics are soft sheets made of textile fibers by various methods. Fabric classification ​ According to the way of composition, it is mainly divided into woven fabric, knitted fabric, nonwoven fabric, ingot woven fabric, woven material, felt and so on. Woven fabric ​ A product made of two systems of yarns (warp and weft) arranged vertically to each other and crisscrossed on the loom in accordance with certain rules, referred to as fabric. Non-woven ​Sheet material made of short fibers or filaments laid directly into a net, or yarn laid into layers, by mechanical or chemical processing. It has short production process, high output, low cost, wide application range and rapid development. Knitted fabric ​ A yarn or group of yarns bent on a needle in a kn

Textile dyeing machine is used to dye the textile materials. Due to the various objects of dyeing and finishing processing, such as textile fiber, yarn, woven fabric and knitted fabric. And they have a variety of production methods and technological requirements in the process of dyeing and finishing processing, So there are many kinds of dyeing and finishing process equipment. Fiber ​Definition of textile fiber ​ Textile fiber, refers to the fineness is very fine, the diameter is generally a few microns to dozens of microns, and the length is a hundred times larger than fineness, more than a thousand times, flexible and fine material.Such as cotton, leaf collateral, hair and so on.Many different kinds of natural fiber, but not all fiber can be used in textile, spinning weaving, only for a certain length (more than a few millimeters), a certain strength and spinnability of fiber, and can be used in the production of textile products, such as yarn, rope, woven fabric, knitted fabric) ca
