Machining Quality Material

The high production in the spinning process to save time leads to the reduction in yarn quality. The technological changes that have occurred today are remarkable. Modern machines reach the production rate of 60 – 100 kilograms/hour which is remarkable when compared to only 5 – 10 kilograms/hour which was possible until 1970. Great advantages have brought us new machinery, as they reduce production time and less physical effort.

Today spinning equipment is fed by rolls directly, the operator, according to the type of machines will be in charge of a section and that section will be constituted from four to eight teams. The fundamental operations applied by the card are stretching and continuous cleaning for the case of natural fibers.

The cotton card differs from the bar in that the latter is larger because of the physical characteristics of the wool, another type of card is the one used for the production of non-wovens that serves to manufacture disposable cleaning materials, mouth covers, layers of diapers etc.

In the conventional spinning processes there is the tendency to omit the flap due to the accommodation or adaptation of continuous production processes, by direct feeding mainly in medium to higher quality fibers, groups of feeders, loaders are used and mixers coupled and in sequence with the card. Although the flap is also still applied in lower quality fibers, for thick articles, for cleaning materials and in opening of short, artificial and synthetic fibers.

Let Your Fantasy Lead Your Wheel

Fantasy threads are made in twists, combining different types of these into various forms. Fantasy threads are used in sweaters and woven dresses, for upholstery fabrics and for the decoration of fabrics for men's and women's suits. These threads are often made with mixtures of natural fibers and made by man. In any case, they are designed for a specific end use, and can be varied by numerous possible combinations of fibers, twists, dubbings and colors.

Types of fantasy threads:

Bouclé

It is one of the most used fantasy threads. Bouclé (French hairlock) is a type of fabric whose surface resembles rip binding. Bouclé is made partly or entirely from hair yarn and effect twirl, often using knots, bumps and slings. It is characterized by tight waves that are projected from the body of the thread at moderately regulated intervals. Bouclé yarn is used for woven sweaters, knitted and flat knit dresses and upholstery fabrics. The fabric can be used for dresses and coats as well. The ratiné yarn is similar in construction to the bouclé, but the waves are continuously twisted and are not spaced.

Chenille Thread/Stumpwork

Chenille is a term derived from a French word meaning caterpillar. It refers to a luxurious yarn especially soft, with hair coming out everywhere. Combed wool is usually mixed with other fibers. This type of chenille yarn is used for clothing made of knitted fabric for external use. In thicker threads, chenille is used to obtain prominent superficial effects on suits and coats. .

Another type of chenille yarn is often called chenille skin, used for chenille rugs.

Metallic Thread

The metal thread is a sheet of metal, aluminum, gold or silver, coated on both sides with a flat or colored plastic film and then cut into narrow ribbons. Plastic-coated metal wires do not become obscured. Metal threads have been produced by joining aluminum sheets between two layers of clear or transparent plastic film. This is the thread called the metal leaf type. A second class called.

Metallic type uses a layer of polyester film (mylar) treated with vaporized metal that is subsequently joined between two layers of transparent film.

Spotted/Mottled Threads

It is made by twisting many times in a short space one end of thread around another, causing some or elongated places (specks) on the surface of the thread. Sometimes a binder is used to hold the speck in place. Specks are usually spaced at varying intervals. Spotted threads are sometimes also called button threads.

Paper Thread

It is made by cutting and twisting wet paper to form individual thread ends, which are then woven into knitting work or in foot and weft fabrics like other threads. Since these yarns have strength they are suitable for making burlap, fiber mats, car seat covers, hats and handbags.

Plastic Thread

It is the coated yarn made of natural or synthetic fibers and that has been submerged in plastic that adheres forming a protective layer. It has the peculiarity of being highly resistant to tensile, elongation and the chemical agents that act on it, advantage that differentiates it from metal threads, very sensitive to oxidation and attack of acidic products.

Splashed

Splashed is the thread with an elongated button that has been twisted forcefully and attached to a base thread. A seed thread is a thread provided with very small buttons, often made from man-made threads and applied to a natural or dyed base thread.

The button is a soft, elongated knuckle. The thread that forms these buttons can be continuous or can be made by wick flakes inserted at intervals between tie-down threads.
