Spindle, Carder, Loom: Tools and Machines in the Textile Industry
Artists use their hands to create a masterpiece. A masterpiece is a mixture of creativity and labor. In the textile industry, artisans use techniques and tools to make yard goods. They study the art of looming, carding, and spindling. They operate small spindles and big looming machines. They learn every technique in looming, as well as every function of tools.
Artisans use three tools in making fabric. These are spindles, looms, and cards. Spindles are small spinning devices. They are used to make yarns. Most spindle products are made up of wood. Spindles have two parts. These are bottom base and spinning stick. The bottom base supports the spinning stick and holds the stick in place. The stick carries spun wool. They bind roving fibers during spinning.
Beginners find it difficult to spin roving on spindles. It takes a lot of time and effort before they learn how to spindle. Yarn ends are tied on the bottom base and spinning stick. Roving is connected to the end rope of the yarn. The spindle is continuously spun clockwise. It twirls individual threads together. After spindling, a roving becomes a yarn. Yarns are used for looming and weaving.
Looms are also used in weaving cloth. They bind threads and yarns together. They are one of the most important devices in textile-making. There are three classes of looms: countermarch, counterbalance, and jack-type. Countermarch looms are the fastest weaving machines. They combine the efficiency of counterbalance and jack-type looms. Machines like Ashford looms weave quietly and steadily; they are the most preferred kind of looms.
On the other hand, carder machines are used to flatten yarns and threads. They prepare rovings and fibers before spindling. They brush raw and washed fibers. Manufacturers such as Ashford drum carder have developed two types of carders. These are hand carders and drum carders. Hand carders are used in flattening small volumes of thread. Drum carders are used in large manufacturing factories. They brush thick piles of thread.
Artisans study the functions and uses of looms, carders, and spindles. Spindle tools like Ashford drop spindle are used in spinning small volumes of roving. In the textile industry, understanding of tools and techniques is a must.

i am making a cng cylinders 232mm diameter 650mm lengh by basalt fiber working presser 200bar burst 450guid me
what is the patern and number of ply or thickness for a cng cylinders 232 mm diameters 650mm lenght by filament winding for 200bar working presser 450bar burst material basalt fiber roving 7um or 13 um 1200 tex
These cylinders are hazardous things and have to satisfy various statutory regulations.
Strongly recommend that you go to a pressure vessel designing team or a good engineering college.
LPG cylinders are made using filament winding technology. I have not seen any for CNG working at such high pressures.
I will be extremely wary of any casual design suggestions you get on public forums for such a serious product.
