What is spunbond fabric and where is it used? A detailed overview of the material

Many people use spunbond fabric on a regular basis without even realizing how versatile it is. This non-woven fabric is well-known for its robustness, adaptability, and variety of uses. Spunbond is most likely the substance used to make commonplace items like shopping bags, medical masks, and gardening supplies.

A unique method of manufacturing the fabric joins the fibers, resulting in a strong, lightweight material. Because of its special construction, it is resistant to water, breathable, and durable. Spunbond is a preferred material in sectors including construction, healthcare, and agriculture because of these features.

However, what precisely is spunbond, and why is it used so frequently? This article delves deeper into the characteristics of spunbond fabric, its manufacturing process, and its various applications in both general and specialized fields.

What type of fabric is this?

A non-woven material composed of polymer fibers is called spunbond. It is made through the spinning process as opposed to the weaving of traditional textile fabrics.

The following is how the material is made:

1. Liquid polypropylene is loaded into the machine, which comes out of small holes, forming long fibers.
2. By means of puncturing, heat treatment or filling with a chemical base, a single web is formed from the fibers.
3. The prepared material is covered with additional impregnations that increase its strength, elasticity and heat resistance.
4. The finished spanbond is twisted into rolls, packaged and transported to warehouses.

Although material is primarily used for technical purposes, it can be produced in a variety of colors. In order to achieve this, liquid polypropylene is first produced with dye added.

The history of origin

One of the earliest non-woven materials to hit the fabric market was Spanbond.

It was determined to begin producing a single, robust, and wear-resistant canvas from polymer fibers in the 1970s, when their production was becoming widely utilized in industry. Thus, Spanbond was made.

As production progressed, several forms of spanbond emerged, including mechanical, thermal, and chemical varieties.

The composition of the fabric and its properties

Companbond is made entirely of polypropylene. Unlike other non-woven materials, it is devoid of additional fibers and adhesive materials.

The fabric always functions perfectly and is very durable because it doesn’t contain any extra impurities.

Characteristics of synthetic textiles:

Because of these qualities, spunbond is a necessary component in manufacturing and is utilized in nearly every industry.

Spunbond fabric is a multipurpose nonwoven material with breathable, strong, and lightweight qualities that is manufactured from synthetic fibers. Protective clothing and garden covers are among the many uses for it in industries that include construction, agriculture, fashion, and healthcare. This article provides a thorough introduction to spunbond fabric, stressing its salient features, advantages, and useful applications in everyday goods.

Types of fabric

A spunbond’s thickness varies. Its surface density can range from 15 g/m 2 to 600 g/m 2.

The way the material is further processed or impregnated also makes a difference:

Agrofibre

The material is impregnated with a substance that shields it from the effects of UV light. As a result, spanbond resists UV rays and does not break down when exposed to them.

Laminated

A unique compound is applied to the fabric, preventing moisture and air from passing through and creating a greenhouse effect.

Painted

Spunbond is frequently painted or given a matching pattern or ornament to help distinguish it from other materials of varying thicknesses or other characteristics.

Spunbond is primarily utilized in agriculture, and there are various varieties of it in this region:

Black

In charge of controlling temperature and humidity, it stops weeds from growing.

White

Prevents plants from freezing or becoming too hot by providing thermoregulation.

FoilBlack and white, red and white

Protects plants’ roots and insulation

Black and yellow

Shields against insect pests

Think about the intended use and extent of spunbond when making your decision. Once you’ve identified the fabric’s key attributes, you can select the appropriate material.

Pros and cons of fabric

Advantages of the material:

• Strength and wear resistance. Due to these indicators, the fabric is resistant to abrasion and remains in the same condition for up to several years, even without minimal care for it.
• Resistance to chemicals and external factors. Due to this, spunbond is often used in industry and agriculture, since it does not rot or deteriorate when treated with chemicals.
• Thermoregulatory properties. The fabric is an insulator and maintains a stable temperature under it.
• Environmental friendliness and safety. Regardless of how you use the fabric, it does not emit toxic and aggressive substances into the air.
• Plasticity. Despite its high strength, it is convenient to work with the fabric – it bends, turns inside out and takes the shape you need.
• Weightlessness. Spunbond is a lightweight material that everyone can work with.

Some disadvantages:

• It is not natural. The fabric is completely made of synthetic polyurethane fibers.
• Permeable to moisture. Due to the corresponding texture, spunbond is not a complete substitute for film, since it is not waterproof.
• When used to cover agricultural crops, it will have to be removed during the day and laid back in the evening. Such actions can be quite annoying for gardeners, especially if they have large sowing areas.

What standards are used in manufacturing? What is taken into account in them?

Spunbond is a purely technical fabric, so in order to produce a high-quality fabric, all specifications and guidelines must be properly followed.

The material is produced in accordance with GOST 57027-2016, which outlines the technical specifications for the produced material:

1. Air permeability – from 1000 to 1900 dm / m s.
2. Changing linear sizes after locking or chemical cleaning – no more than 2.5%.
3. Resistance to repeated compression – at least 70%.
4. Thickness at a pressure of 0.2 kPa – from 3.5 to 10.0 mm.
5. Total thermal resistance – from 0.25 to 0.45 m ° C / W.
6. Folds and creases from winding at the beginning of the roll – no more than 1 m.

Rolls of packaged material are generally kept in dry rooms in a vertical position, one meter away from sources of heat and shielded from UV and direct sunlight.

Because of its special qualities, spunbond fabric has emerged as a versatile material used in many different industries. It is a great option for medical supplies, furniture protection, and agricultural covers due to its lightweight, breathable, and durable qualities.

Spunbond stands out due to its cost-effectiveness and useful features. This non-woven material is constantly finding new uses, from maintaining hospital hygiene to promoting plant growth.

Spunbond is a fabric that is both durable and versatile, offering a good mix between cost and quality. You should give it some thought for your upcoming project.
