The modern textile industry pleases with more and more new inventions. Thanks to them, sewing becomes easier, and most importantly faster. Among the most accustomed of her achievements is a reinforced thread. Let's learn about its properties, varieties, and determine the purpose of application.

What is reinforcement?

To better understand the features of the type of threads in question, it is worth knowing what kind of process is called reinforcement. So called various ways to strengthen one material by combining it with a more durable other. It is the properties of the latter that are partially transferred to the former, improving its own characteristics.

Reinforcement is widely used in completely different industries. In the textile industry, cosmetology, in the construction of roads, the manufacture of reinforced concrete and stone structures, glass products, films, ceramics, gypsum, etc. By the way, the concept of "reinforcement" known to all of us is more than closely related to this process. These metal rods just serve to strengthen reinforced concrete structures.

Reinforced sewing thread

Quite often, having heard such a name, some correlate the type of thread being studied with those that contain Lurex. However, this is a mistake. Both types are completely different. The fact is that Lurex (although it can be metallized or coated with foil) does not differ in particular strength. The purpose of these additives is to decorate products.

At the same time, from the very name "reinforced thread" you can guess that its fibers are more durable compared to other varieties. But unlike Lurex, no metallic elements or their derivatives are used here.

This type of thread is also called "framework". They are twisted weave. Moreover, the core is made from one type of fiber, and its braid is made from another. Due to this, incredible strength and durability are achieved, for which the reinforced thread is famous for

Distinctive Features

Features of this species are determined by their components and production methods.

The core of polyester fibers gives a special strength to the reinforced thread. Natural or mixed fibers are used as winding. This is done in order to protect the synthetic core from melting during ironing, washing or other exposure to high temperatures. Braiding also extends the life of the thread-carrying parts of sewing equipment by reducing the coefficient of friction by up to 15% (compared to fully synthetic threads). For this reasonthe reinforced look is often used for overlocks.

Such threads provide high strength connection of sewing parts, as well as minimal shrinkage during wet heat treatment. Due to their versatility, they are equally applicable in the clothing, knitwear, footwear, leather goods industries.

Varieties

There are three types of thread of this kind. They are distinguished by the type of fibers used to braid the polyester complex core. To understand which one is in front of you, you should pay attention to the two letters indicated on the reel. The first of them is always "L". It is the same for everyone and means the core of the thread - complex low-shrink polyester fibers. The second is the name of the braid.

• Marking "LL" means that the outer part of the thread is polyester staple fiber, it is also lavsan. This variety is considered universal. It provides high strength connection of sewing parts. As well as good appearance and elasticity of the seam. Most often used for overcasting cuts, less often for finishing stitches.



• In "LS" the second component is the siblon.
• Marking "LH" means that threads of fine-staple cotton act as a winding. Although they are less durable and wear-resistant than LL, they are able to withstand temperatures up to 200 degrees.

In addition to the composition, the studied species also differs in footage. For domestic needs, reels of 100-200 m are more often sold.the amount is enough for those who sew rarely or in small quantities.

Reinforced thread 1000m, 2500m, 3000m is produced for professionals who work almost every day.

There is an opinion that the figure before the marking is the footage of the reel. It's a delusion. In fact, these figures mean the approximate nominal linear density of threads and are measured in tex. The most common reinforced thread 45 is LL. This means that its linear nominal density is approximately and equal to 45 tex. More precisely 43.5 tex.

The most common sizes are 35, 36, 44, 45, 65, 70 and 80.

It is worth remembering that such marking is typical for bobbins produced only at the Spinning and Thread Mill named after. CM. Kirov. At the same time, most foreign manufacturers do not have it. Therefore, before buying, you should consult the seller.

Scope of application

This type of thread is ideal for securing or closing seams on any thickness of fabric. Their high tear strength and wear resistance result in smooth seams.

They are also used in the production of high-strength fabrics. As a rule, intended for sewing industrial protective suits, as well as clothes for the military and emergency workers.

There are far more than one type of fabric with reinforced thread. They differ not only in its variety, but also in the way of spinning.

The best quality materials are those that have andduck, and carcass threads are located on the warp. They act as a mesh-base, between the fibers of which cotton components are more densely spun. This design allows the material not to interfere with the body's thermoregulation, but at the same time to be more wear-resistant and tear-resistant.

Thread lifting

You can reinforce not only reinforced concrete structures, fabrics and fibers, but also the face. This procedure is becoming increasingly popular in cosmetology today. Its essence is that special hypoallergenic threads compatible with the human body are introduced under the skin. Their distribution in a certain order helps the face stay in good shape.

Reinforcement, or thread lifting also helps to smooth out wrinkles and improve the overall condition of the epidermis. It also helps fight double chin and some other age-related changes. The procedure is most often indicated for patients over 50, but not older than 60.

Which threads are used?

Specialized reinforcing threads are used for lifting. Not reinforced! The difference is that in the first case they serve as a reinforcing element. In the second, they themselves underwent a hardening procedure.

There are several varieties of them that differ in composition.

• The so-called "golden" threads. Steel will be used to reinforce the face among the first. In their composition, indeed, there is a noble aurum. However, most of it is caprolactam and polylactic acid.
• Polypropylene orcaprolactam. Thanks to microscopic notches, they keep their shape better. It is believed that their service life is 3-6 years.
• Threads based on non-absorbable polypropylene composition. They serve up to 7 years.
• 3D mesothreads coated with lactic acid.
• Silicone.

Reinforced film

Threads are used to strengthen not only the tissues and skin of the face, but also ordinary polyethylene film for greenhouses. Thanks to the use of a mesh base of them, the material retains the advantages of a conventional film. In addition, it acquires increased resistance to mechanical stress, more reliably protecting against wind, hail, snowfall and temperature changes.

In fact, the so-called "reinforced" film consists of two regular sheets, welded onto a mesh frame. Its threads can be made from different materials:

• dacron;
• fiberglass;
• polypropylene;
• HDPE.

The size of the grid cells, as well as its color, may also differ.

The use of films with reinforcing threads in greenhouses and greenhouses, according to reviews, can increase its service life by an average of 5 years.
