  What is color fastness to light? As we all know, textiles are usually exposed to light during their use life, and light has the potential to destroy the dye, resulting in the effect of “fading,” which causes colored textiles to change color, usually light or dark. We call the degree of resistance to the fading effect of light as color fastness to light. The color fastness to light is a very important index in physical testing of textiles. And light fastness tester is the machine for the test. How to test the color fastness to light? The test method of color fastness to light is exposing a set of reference samples along with the specimens at the same time and under the same conditions; the color fastness to light is assessed by comparing the change in color of the test specimen with that of the reference materials used. Color fastness to light can also be divided into: sunlight (which can be exposed to several different colors of sunlight) and artificial light (xenon arc or carbon arc

  What is yarn spinning Yarn spinning is the technique of making yarn from fibers. The fibers can be wool, cotton or other natural materials, or they can be synthetic. Spinning produces a yarn that can then be used to make fabric. Types of yarn spinning Spinning can take numerous forms, but they all have the same goal: to transform fibers into yarn. Some varieties of spinning are more popular than others, but each has its own set of benefits. Woolen and cotton are the two most common forms of spinning. The process of converting raw wool into yarn is known as spinning. The yarn is generally thick and heavy since it is spun on a spinning wheel. Cotton spinning is the transformation of raw cotton into yarn. The yarn is generally thin and light, and it is spun on a spinning wheel or spinning jenny. There are also additional styles of spinning that are less common but have their own advantages. The process of converting raw silk into yarn is known as silk spinning. The yarn is generally ver

  Spinning is a very ancient activity, and people have understood how to spin small fibers into long threads, which are subsequently weaved into cloth since prehistoric times. Spinning process, in general, is the act of twisting animal or vegetable fibers to make a continuous and infinitely expanding thread ideal for weaving. Cotton spinning is the technique of spinning random short fibers such as raw cotton into continuous cotton yarn or cotton mixed yarn. Spinning is the process of transforming disordered fibers into fiber aggregates. Compressed cotton bales enter the cotton spinning mill as raw cotton. The fibers are blocky and disorganized, with different contaminants and flaws. As a result, it is important to loosen first and then assemble when spinning, that is, to break the superfluous link between fibers and remove them. Impurity flaws are organized axially to generate slivers of the desired thickness, which are then appropriately twisted to form cotton yarn. Cleaning, carding,

  Cotton spinning machine is defined as machines that process (or spin) prepared cotton roving into useable yarn or thread. The followings are the history of cotton spinning machine. Early spinning tools The first spinning tools were quite basic, consisting merely of a spindle and a winding rod. The loose fibers are twisted into yarn by spinning the spindle like a top, which is then coiled on a winding rod. The Indians developed this crude instrument and turned it into a spinning wheel, which replaced the hand spinning spindle with technology, but only one yarn could be produced. Spinning wheel In 1030, the Islamic world created the spinning wheel. It later spread to China around 1090, and then to Europe and India in the 13th century via the Islamic world. All spinning was done by hand using spinning wheels until the 1740s. The Jersey wheel was the most sophisticated spinning wheel in Britain, but as an alternative, the Saxon wheel was a double-belt treaded spinning wheel in which the
