With the growth of the consumer market, the demand for packaging products has increased. It turned out to be unprofitable to make it from natural materials. Manufacturers have begun to use synthetics, which are more convenient to use and simplify the production process, making costs minimal. Polypropylene thread has become one of the types of such products. 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 production of packaging materials such as 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. During the production of polypropylene yarn, gas is used andpropylene.

Production technology

In the production of polypropylene thread, it is necessary to apply modern technologies and use trained personnel. The thread is made by extrusion, in which the material is heated and passed under pressure through special nozzles with small holes. Here propylene is separated into thin threads. Subsequently, they are entangled together using pneumatics and cooled. This material is highly durable 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 threads to acquire a certain color required 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 activity, increase heat and light resistance.

Types of threads

There are three main types of polypropylene threads.

Fibril threads are a unique type of product made by applying high temperatures and drawing 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 that give it high resistance to negative influencesultraviolet radiation. Changes in humidity and temperature also do not affect 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 low 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.

Use

The list of products based on polypropylene threads 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 carpets and stadiums. Ropes and twine, clothing and footwear, a lot of packaging materials are produced from polypropylene yarn. It is also used in agriculture for gartering some plants.
