With the growth of the consumption market, the demand for packaging products increased. It turned out to be disadvantageous to make it from natural materials. Manufacturers began to use synthetics, which are more convenient to use and simplify the production process, making costs minimal. One of the types of such products was polypropylene thread. It can be used in almost all packaging materials.
What is polypropylene thread
This is a unique synthetic material, which is a white thread without the use of dyes. It is used in the manufacture of packaging materials, for example, polypropylene bags of various sizes. It is also used in construction, for the manufacture of rope material, as well as some synthetic clothing. The product is considered simple and inexpensive to manufacture. In the production process of polypropylene yarn, gas and propylene are used.
Manufacturing technology
In the production of polypropylene yarn, it is necessary to apply modern technology and use trained personnel. The thread is made by extrusion, in which the material is heated and under pressure passed through special nozzles with small holes. Here propylene is divided into thin filaments. Subsequently, they are confused together using pneumatics and cooled. This material is high strength and is considered almost finished product.
Before the release of finished products, various types of processing of the prepared material are used. For example, dyes are added to polypropylene yarns to acquire a certain color, which is necessary for the consumer, as well as some chemical additives until the material reaches the required qualities. The use of additives improves the characteristics of the thread, can also give it antistatic properties, increase the color palette, provide antimicrobial action, increase thermal and light stability.
Types of threads
There are three main types of polypropylene yarns.
Fibril filaments are a unique type of product manufactured using high temperatures and stretching the material under high pressure. During operation, such a thread does not increase in length and does not change its mechanical properties over time.
Multifilament polypropylene thread incorporates various types of additives, which give it high resistance to the negative effects of ultraviolet radiation. Changes in humidity and temperature also have no effect on the thread. It is not subject to destruction from such types of deformation as bending and abrasion.
Textured polypropylene thread is widely used, as it has ultra-high elasticity with a small volume. The thread itself has a porous structure, which distinguishes it from other similar polypropylene materials. Popularity is also given by various types of thread color palette. This expands the range of its application for the consumer.
Using
The list of products based on polypropylene yarns of artificial origin is constantly updated. The thread has found its application in most countries of the world. It is used in medicine and cosmetology, as well as for the manufacture of washcloths. The production of technical textiles is not possible without the use of this material. It is added to carpeting and stadium coverings. Ropes and twine, clothes and shoes, a lot of packaging materials are made from polypropylene yarn. It is also used in agriculture to garter some plants.
