Spunbond material: what it is, properties and application
Nonwoven materials, we have long been used in various kinds of activities. For the manufacture of non-woven fabrics in the production of new special technology developed.
One result of them, known to many specialists in different branches of industry, is a spunbond material. About it and its possible applications are discussed in this article.
Let's look at what it is - spunbond, consider the properties and application of this material. Spunbond - non-woven fabric, those. derived from fibers or filaments without the aid of looms. More precisely - the name of one of the technological methods of manufacturing non-woven materials, but among professionals so called material itself.
Raw enough It is widely used because of its unique properties, quality and affordable prices. Firstly, spunbond is environmentally friendly raw materials.
Compared to its peers advantage is a high strength, stability, as an acidic medium, and alkaline. It has a low density, which makes it easy.
Also breathable, abrasion-resistant and thermostable enough.
manufacturing methods, standards and GOSTS
spunbond It refers to a geotextile, as the raw material for its manufacture are fiber-forming polymers, among which the most used - polypropylene, and among the manufacturing methods - spunbonded.
Spinnerets - a special form of high strength for punching of different plastic materials. Use of a spinneret for melt polymer allows to obtain a thin continuous filaments forming the textile web.
These filaments are held together needling or thermal bonding calender - a special machine which allows continuously molded polymer sheet by passing it between the rollers during their rotation.
From lumen therebetween, their length, diameter web acquires the required thickness and width. Such machines are known to many of laundry. That they provide ironing with simultaneous drying things.
Bonding the filaments may be formed and the water-jet method, and hot air, and the chemical impregnated filaments. The method of bonding yarns It depends on the characteristics of the raw material and its scope.
spunbond manufacturing technology involves two mandatory stages - molding and subsequent bonding fibers of the web. But there is a third phase consisting of additional finishing of paintings - painting, impregnation by special trains, and so on.
Material well colored. A process of making a color svetostabilizatornyh dye mixtures and in the form of masterbatches added spunbond lightfastness. UV protection from burning and destruction provides a supplement designed specifically for this purpose.
If necessary, establishing the thickness, density and surface water permeability of such materials are the relevant standards thereto:
- GOST 50276-92 (ISO 9863-90) "The method of determining the thickness under certain pressure";
- GOST 50277-92 (ISO 9864-90) "Method for determining the surface density";
- GOST P 52608-2006 "Methods for determination of water permeability."
One of the main characteristics of for nonwovens recognized their density. Due to the different technological approaches, spunbond density can vary from 15 to 600 g / km.m.
Spunbonded needle punched surface has a high density (above 150 g / sq.m.). It has defined its use as bases in floor coverings and roofing.
Thermobonded spunbond - is the easiest of all the varieties of material density, because of less than 150 g / sq.m. That is why it the most widely used for different purposes in the diverse spheres of human activity.
As a geotextile is used and thermobonded snanbond. For these purposes, the density can vary in the range from 15 to 150 g / sq.m.
In addition to density index is taken into account:
- firmness and endurance, ie how durable at all loads and how quickly returns original form;
- breaking load;
- heat resistance and cold resistance (heat resistance);
- electrical conductivity.
It must be said that the fabric spunbond has low electroconductivity and excellent properties regarding the above mentioned requirements. Characterized by the geometric properties of raw size, which is important for air permeability, rigidity, insulation, etc. The advantages include easy cut, regardless of size.
From the point of view of hygiene properties Spunbond does not react in the air and waste waters with toxic-noxious substances, can not be affected by mold and rot, and therefore is environmentally friendly.
On the advantages and disadvantages of twill fabric, as well as the methods of its application, we describe in a detailed review.

Applications are varied. It is used in construction:
- roads and parking lots;
- railways and airports reconstruction;
- playgrounds for sports;
- To strengthen the surface of the pipeline;
- for strengthening of embankments, slopes;
- to protect the slopes from erosion;
- for landscaping;
- construction of objects of hydraulic engineering;
- Water for landscaping designs shores.
In horticulture, spunbond fabrics are Covering the best non-woven fabric, visual application is presented in the video:
The unique properties of spunbond and noticed manufacturers of upholstered furniture, bedding, bags. Thanks to him, the product of non-woven fabrics become more attractive. In the production of various bags and back packs products used to perform functions, gives the product extra rigidity without weighting (strengthening the seams, intermediate pads).
Car covers, produced using spunbond acquire clear and beautiful shape, endurance and durability. Packaging and cases for many products are not without their use.
Manufacture of working clothes and sanitary products
Special attention should be paid to the production of spunbond disposable clothing, workwear and uniforms. Here it is simply indispensable for strengthening collars, racks, valves on the pockets and cuffs.
Slippers, cap, gown and suit of spunbond presented in the photo:
But its priceless opportunity - to do material resistant to UV radiation and antistatics the desired color - could not ignore medicine. Spunbond allowed to make the products anti-allergenic, non-toxic, with the possibility of sterile processing. It is because it is made of disposable clothing for medics. First of all, it is disposable kits for operations, protective masks and respirators.
No less important, such clothing in the food industry, salons cosmetics and the service sector. There can meet various coloring coats, capes, costumes and the like, including disposable.
In tailoring products for medicine is becoming popular spunbond laminate (two-layer), which is manufactured by the technology eliminating stratification and increasing the strength and water resistance. It is important for medical devices, as they should be krovoottalkivayuschimi.
This The material is soft and pleasant, which makes the product more comfortable during the operation. Such spunbond necessary in some products for the food industry.
Briefly on the prices and rules of care
The article discussed about the low price of raw materials, which directly depends on the properties: density, thickness and width of the product, the manufacturer, etc. The price may be set per square meter, or, a roll or a specific product. Per sq. m. fluctuates depending on the density and the destination from 1 to 60 rubles.
Treatment of products from spunbond simple. If the product is a one-off, it does not require maintenance. It is only necessary to correctly choose the material for a particular purpose, that thing lasts long.

Covering material spunbond: overview, characteristics, application, reviews
Modern industry is working to facilitate a person's life, including his economic activities. Thus, in agriculture it is quite popular spunbond - non-woven material made on the basis of the thinnest polymeric fibers and filaments. By the way, the technology of its production is called similarly - spunbond.
Thanks to the unique properties of such materials, surpassing many traditional fabrics, is widely used in many areas of human activity, such as:
- Agriculture. It is used in the regeneration of greenhouses, as a covering fabric for plant protection from weeds, promotes the preservation of the crop.
- Building. It is used as an insulating material in paving roads, pipelines, highways, for reinforcing embankments.
- Medicine. Demand for sewing disposable sets of clothing and bedding, respirators and face masks.
- Chemical industry. Is the basis for impermeable outer layer of hygienic products for women and children.
- Furniture manufacturing. Podshivnoy material - an excellent replacement for natural fabrics.
The advantages of a unique material
The advantages of spunbond is attributed:
- Environmentally friendly. Even with strong heating the material does not release into the environment of harmful substances, so is safe for humans and plants.
- High strength. Caused by increased hardness of polypropylene filaments, providing web wearproof qualities.
- Versatility. Used in various sectors (agriculture, industry, medicine, construction, etc.).
- Ensuring protection. When used in greenhouses to prevent freezing out landings and the impact of the burning rays of the sun.
- wear resistance. Does not corrode, is not affected by fungus and micro-organisms can not be rotted.
- Permeability. Excellent conducts air and moisture, do not get wet and stores under a microclimate, which is especially important in horticulture.
- stability to temperature, acid and alkaline media.
- Ease, virtually weightless, due to a low density material.
- Low price.
The main parameter is the density of the spunbond: 15 g / m 2 to 160 g / m 2. It determines the thickness of the material. The width also has different values. Covering material - spunbond, which is used for agricultural purposes, often produce a width of 160 and 320 centimeters.
It is worth noting that in addition to the density in the production of non-woven fabrics are taken into account such factors as:
- conductivity. It must be low.
- Endurance and flexibility. Otherwise - how durable the material under load and how quickly restores the original shape.
- Breaking load.
- Frost resistance and heat resistance.
Use in agriculture
Spunbond produced in several forms, depending on the destination. Adjustments and enhance the performance achieved by the aid of dyes adding new tissue obtained by combining a unique material with different fundamentals. One agrotextile (otherwise agrovoloknom). It contains a part of special stabilizers, ultraviolet extinguishing and preventing the degradation of the material under the influence of the sun. Spunbond - covering material intended for crop production.
Previously polyethylene film used in this capacity. Is it better to spunbond or a film? The latter in comparison with modern analogue has some significant disadvantages: not breathable, collapses sunlight, rain accumulates moisture on the surface, the soil is dry. Unsuitable mulching. It characterized by low abrasion resistance, since it is easily damaged by sharp edges of greenhouses. Of course, the polyethylene to protect from the wind, but the crops covered with a film requires daily attention, which is not true of the spunbond, which can safely be left to the seedlings days for seven to ten. With plants did not happen: precipitation will pour, will provide air circulation, condensation will not meet. However, the best solution would be a combination of these materials with the use of their positive aspects.
One variety of spunbond agrovoloknom is black, which is used most often in mulching. Under such agrovoloknom not grow weeds, increased soil temperature, retains moisture, which eliminates gardener once again watered land. For example, the marking "SF 60" on spunbond indicates that its density - 60 g / m 2. By the way, FMS stands for "stabilizer against UV light." For greenhouses used light covering material spunbond perfectly leaky and water. Seedlings in growth raises the light fabric, which does not cause her absolutely no harm.
White spunbond having a density of 17 indicators, 30, 42, to protect vegetable crops from frost, temperature changes and pests. This is a fairly popular material for covering greenhouses. Since it is easy to operate, it can withstand a long service life, it is kept perfectly in any environment. Plants in a greenhouse to breathe well, they are protected from the wind, rain penetrate inside.
Color variation web sufficiently bright and dense (up to 50 g / m 2) and more used for decorative purposes (for sewing bags, cases, in furniture, medical supplies).
Spunbond polypropylene laminate is characterized by the foundation does not give access to air and moisture. density index - from 42 to 65 g / m 2. It demands in the medical industry due to the strength, durability, rigidity.
The high demand for spunbond led manufacturers interested (both domestic and foreign) to release such material. Most spunbond in the domestic market is represented by the Chinese producers, even surprising. Of domestic companies is to provide "Himkor9raquo ;," Geksa9raquo ;, "Sibur-Geotekstil9raquo ;.
Price depends on the non-woven fabric characteristics, manufacturer and purpose. Thus, packing a thin spunbond 2.1 m * 10 m a density of 17 g / m 2 is approximately 150 rubles. The web with the index of 80 g / m 2 would cost 50 rubles per linear meter. Color thin material will be assessed by the seller in the 25 rub / rm. m.
Roll white ukryvnogo spunbond material (150 n. M) density of 60 g / m 2 is about 3600 rubles.
Customers speak highly of spunbond, the characteristics of which are discussed in the article, as a high-quality protective materials to help save the crop intact. Invasion of weeds, frequent watering is no longer concerned about the gardener, releasing its precious time for other, more important things. Black spunbond protects plants from the hot rays of the sun and provide them with needed shade and a comfortable environment for qualitative growth.
Spunbond - a relatively new material, which has become popular due to the high quality characteristics. It has a homogeneous structure that provides the creation of a favorable microclimate in the regeneration of greenhouses. It guarantees a constant air flow and a uniform distribution of precipitation easily transmit moisture. Due to the ease it does not damage even the most fragile fruit. It does not pollute the environment.
What spunbond: application characteristics and a covering material
The last 10 years on the vegetable growing and gardening workshops and forums, there is an active discussion of the advantages and features of the new sheltered spunbond material.
Already many gardeners successfully use the material on their sites, but not all are aware of the directions of its application. When this technology is not standing still, and manufacturers are constantly making adjustments to it that allows you to expand the list of products and open up new opportunities for the application.
What is a spunbond and where it can be used?
To better understand what a spunbond, it is necessary to study its production technology. The product was obtained from the molten polymer fine fibers which enter the air stream and deposited into a web.
The result is a durable, wear-resistant and durable non-woven fabric, which has found wide application, including in agriculture. For extended use of the polymeric material under ultraviolet sunlight technology provided by inclusion in the melt agrovoloknom stabilizers.
In horticulture use agrovoloknom density of from 17 to 60-80 g / m2 depending on the immediate purpose. Spunbond used both in open and in greenhouses.
Conventionally, there are three main areas where the covering material of spunbond may be used: accelerating soil warming and receiving earlier germination, protection of topsoil from drying and savings in watering plants with protection from severe winter hardiness low frost. However, the application is not limited to spunbond.
Spunbond properties and features of the application in different seasons
Before describing the effect agrovoloknom on plant growth and yield formation, it is necessary to consider its basic characteristics:
- good breathability (the lower the density, the more intense gas exchange);
- homogeneous structure (guarantee uniform distribution of moisture and heat and maintaining a constant microclimate);
- light transmission (may vary depending on the purpose);
- high thermal insulation properties (also directly dependent on the density);
- low specific gravity, not to put pressure even on young shoots;
- High-strength, abrasion and crease resistance (which makes practical and durable material);
- resistance to adverse weather conditions (no change its properties at temperatures of -55 to 100 ºC);
- not exposed putrefactive bacteria and mold;
- inert to various chemical compounds (pesticides treatment does not affect the state of the material);
- It is not toxic to plants and future harvest.
Presented properties can vary somewhat depending on the type and manufacturer of non-woven fabric.
The use of spunbond is possible at any time of the year. In the spring it is used to accelerate the heating of the beds with a view of the earlier crops. At the same time it protects the seedlings have emerged from the low night temperatures and the return of frost, serves to seeds and young shoots shelter from birds and rodents, retains moisture in the soil and slows erosion, preventing the action of the strong spring winds.
Besides white spunbond density of 42 and 60 g / m2 can cover frames beds, greenhouse or glasshouse. This provides an optimum light level, there is no condensate, and set protection against cold and frost hailstorms.
With the onset of summer agrovoloknom a reliable mulch material, retaining moisture, preventing overheating of the root system and slowing the growth of weeds. Furthermore, spunbond an obstacle for a number of hazardous pests (e.g., for slugs and medvedok).
Use of a material in horticulture (plantations strawberry, gooseberry, currant, blackberry) reduces the degree of development of disease caused by contact with moist soil berries. This primarily refers to the botrytis, the causative agent of which is any soil.
Using spunbond in autumn period may extend many fruiting crops by protecting them against abrupt cooling and differential night and daytime temperatures. Thus, it is possible to extend the growing season, which is especially important for the Far East and Siberia. Also in the fall agrovoloknom effectively used for the preparation of plants, wintering in the open field, to lower the temperature.
Timely cover nonwoven perennial plants enables complete transition to step deep rest and serves as a reliable protection of the root system from the first frosts when there is no snow cover.
Winter spunbond protects podzimny crops, saplings of fruit and berry crops, ornamental plants transplanted from weather extremes: extreme cold, lack of snow, strong winds, the formation of ice crust after the thaw, bulging of the root system.
Regardless of the season agrovoloknom is used in greenhouse vegetable production, allowing to extend the circulation of vegetables. Also nestled spunbond beds are left clean and beautiful fruit on tomato fruit rot development is excluded.
Of course, for various works used different types of covering material, endowed with these or other qualities. For agriculture, producing white, black and bicolor spunbond different densities.
White passes the sun's rays and plants under it successfully developed. Black, on the contrary, inhibits the growth of plants, so is used as a mulch cover.
Spunbond range is not limited to species from different manufacturers has its own set of variations in the density and interesting solutions in the form of finished products (shelterbelts, tree trunks, soft containers) for the industrial and private gardening.
Spunbond or polyethylene film
Perhaps some truckers are still doubts about the transition to the non-woven fabric. Many continue for winter shelters and greenhouses use plastic. Lowering the price issue, we shall understand that better, spunbond or a film?
From this analysis it can be concluded that the polyethylene film is obsolete material unable to create optimum conditions for plant growth and development.
Manufacturers and retail price
The leading brands of the nonwoven material for agriculture are Lutrasil (Freudenberg, Germany), Agril (Avintiv, France), Agrotex (GK hex Russia), Agrin (UNISPAL, Ukraine) and Plant-Protex (Poland). In the Russian market can be purchased from any manufacturer spunbond official representatives and regional managers or in gardening stores.
For farms covering material sold in rolls of 100 m or more, most demanded width of 160 or 320 cm. In order to design product dimensions vary. For the needs of truckers manufacturers produce leaf length of 10 m.
On the Internet you can find specialty shops offering spunbond on the manufacturer's price, while at the wholesale attached additional discounts. However, even retail is quite acceptable for a private holiday home. On the formation of prices per square meter affected by the density of the material and the type of spunbond.
For wholesalers average price spunbond with a density of 42 g / m2 of 3- 6 RUB / m2, a density of 60 -. 80 g / m2 cost 7 - 12 rub / m2.. Average retail price (at 2016 year) of the packaging webs in the range from 10 m to 170 (the width of 320 cm, density 17 g / m2) to 550 rubles. (Width 320 cm, density 60 g / m2).
