What is lavsan – properties and application of fabric

Lavsan is a fabric that is becoming more and more popular in the apparel industry. It is versatile. This particular type of polyester is well-known for its practicality and durability, and it has a number of benefits over other materials. Whether you’re new to it or already familiar with Lavsan, knowing its characteristics will help you choose your clothes wisely.

Lavsan’s strength is one of its most notable qualities. This fabric is a great option for clothing that needs to withstand regular use because it doesn’t easily tear or deteriorate. Additionally, it resists wrinkles very well, so you won’t need to do much maintenance to keep your clothes looking crisp and new.

Lavsan is renowned for its exceptional color retention as well. Lavsan fabrics hold their vivid colors through multiple washings, keeping your clothes looking brand-new for an extended period of time. It also dries quickly, making it perfect for hectic lives where time efficiency is essential.

Lavsan finds usage in a wide range of apparel items, ranging from formal to casual wear. Its attractiveness and blend of durability make it a popular option for uniforms, sportswear, and everything in between.

Origin and description

What is polyethylene terephthalate? It turns out that it goes by different names in different countries: polyester is called terylene in Germany, dacron in the USA, tetoron in Japan, and tergal in France.

The fiber made from polyethylene terephthalate was known as lavsan in the USSR, named for the laboratory of high-molecular compounds of the Academy of Sciences where it was developed.

Lavsan is a synthetic fiber that falls under the polyethylene terephthalate (PET, PETF, PET) category of polyester fibers.

Polyesters are high-molecular compounds made up of ester groups connecting individual macromolecule links. Polyesters provided the most polyethylene terephthalate, both in terms of practical distribution and popularity. It is made up of linear macromolecules with functional groups arranged in a predictable way. These macromolecules have a long, stiff elongation.

Lavsan is a polyester fabric type that is well-known for its affordability, resilience to wrinkling, and durability. Because of its strength and ease of maintenance, this synthetic material is widely used in textiles for homes and apparel. Because of its qualities, lavsan is a popular material for both specialty clothing and daily wear because it strikes a balance between performance and practicality.

Structure and composition

Polyethylene terephthalate fibers are round in cross-section and have a smooth surface. Their structure makes materials made of them prone to pilling. Profiled fibers have therefore seen increased use in the textile sector. which come in different cross-sectional shapes. Profiled fiber-based materials are less prone to pilling.

Properties

Elasticity is one of lavsan’s characteristics. They deform completely reversibly when stretched by 5–7%, and materials made of them come out of the wrinkles.

• Polyester fibers have low hygroscopicity, therefore, in a wet state, the mechanical properties and properties of materials made from these fibers (strength, elongation, creasing, resistance to repeated deformation) do not change.
• The wear resistance of lavsan materials is also an indicator of their wide application in the manufacture of mixed fabrics and canvases. They are inferior in this only to polyamide fibers, but they are much more resistant to abrasion than all natural and artificial ones.
• Also, a positive property of lavsan is its resistance to the effects of most microorganisms.

Every feature of lavsan fiber has an impact on the mechanical and physicochemical properties of materials.

Polyester fiber fabrics have advantages as well as disadvantages.

Advantages and disadvantages

They make canvases and other fabrics incredibly resilient to tearing. Positive qualities of these materials include their resistance to deformation and wrinkles. This laid the groundwork for the broad usage of these kinds of textiles and canvases in apparel and interior design production.

1. The negative properties of lavsan materials include their low hygroscopicity of 0.4%. They practically do not absorb water. However, this property can be useful in the manufacture of clothing for many types of sports. Products made of polyester materials remove moisture to the outside and dry quickly.
2. Materials made of polyester fibers have low lightfastness and low heat resistance. Therefore, it is necessary to iron products that contain lavsan threads at a temperature not exceeding 150 0 C and avoid prolonged exposure to sunlight.
3. It is also highly electrified.

You can estimate the amount of synthetic fiber in fabric or linen using the organoleptic method. It releases black soot when it comes into contact with flames and burns with a light yellowish flame. We’ll see a hard black ball once it has subsided.

Application

Textile industry materials made entirely of lavsan are robust and long-lasting. They don’t need any extra attention. These textiles can be the following when different thicknesses of threads and weavings are used:

• dress blouses and suits;
• curtains, tulle and furniture;
• special materials;
• tent;
• tabletops;
• ropes;
• faux fur;
• In their pure form, polyester fibers are used to make non-woven fabrics – padding polyester, holofiber, and they are also used to produce sewing threads.

Polyester-based blouse and dress fabrics drape beautifully, lend themselves to pleating, ruffles, and folds, and let you work with a wide range of models.

Lavsan is a well-liked option in the fabric industry because of its reputation for strength and adaptability. This synthetic fiber is well-known for being resilient to fading, stretching, and wrinkles, which makes it a useful choice for regular use in a variety of settings.

Its broad application in home textiles and fashion is partly due to its capacity to hold color and shape. Lavsan textiles are popular for upholstery and clothing because they are smooth and comfortable to the touch, and they are also simple to maintain.

When it comes to clothing or household items, Lavsan provides a dependable option that strikes a balance between cost and functionality. Given its usefulness, this fabric is worth taking into account for your upcoming project.
