Adding stretch to polyester filament fabric without spandex

A dress made of polyester fabric can be made stretchy without using a polyester elastane blended yarn through one of the following methods. Polyester filament fabric on its own is naturally not very stretchy. However, there are several ways to achieve stretch in polyester fabrics without using spandex. Here are some ways.

Mechanical stretch

Mechanical stretch can be done through several methods.

Crimping: This involves physically altering the shape of the polyester fibers to create coils or waves. When the fabric is stretched, these coils straighten out, providing elasticity. Crimped polyester fabrics are commonly used for active wear and sportswear.

 

Knitting: The specific knitting pattern used can also affect the stretch of the fabric. For example, certain types of knitted fabrics, such as jersey and interlock, have inherent stretch due to the way the loops of yarn are interlocked.

 

Weaving: The weave of the fabric can also play a role in stretch. For example, a looser weave will generally be stretchier than a tighter weave.

Bicomponent fibers

These fibers are made from two different polymers with different properties. One of the polymers is typically polyester, while the other is a more elastic polymer, such as polyethylene glycol (PEG). The two polymers are bonded together in a specific way to create a fiber that has both the strength and durability of polyester and the stretch of the other polymer.

 

Chemical treatments

Certain chemical treatments can be applied to polyester fabrics to make them more elastic. These treatments typically work by modifying the surface of the fibers, making them more slippery and allowing them to slide past each other more easily when the fabric is stretched.

 

The type of spandex-free stretch that is best for a particular application will depend on the desired level of stretch, the weight and drape of the fabric, and the cost. Mechanical stretch is generally the most cost-effective option, but it may not provide as much stretch as other methods. Bicomponent fibers and chemical treatments can provide more stretch, but they can also be more expensive.

 

More on spandex-free stretch in polyester fabrics

  • The amount of stretch that can be achieved without spandex is generally limited. If you need a fabric with a very high degree of stretch, you may need to use a blend of polyester and spandex.
  • Spandex-free stretch fabrics may not be as durable as fabrics that contain spandex. They may be more prone to tearing and pilling.
  • Spandex-free stretch fabrics may not be as comfortable as fabrics that contain spandex. They may feel stiffer and less breathable.

 

Different types of a polyester stretch

Depending on the fibers and the fabric blend, polyester can be stretchier than it would have been on its own. This is done through a range of techniques and machinery. Knit, stretch-weave and warp-knit fabric are the most common methods. Here’s a closer look at the different types of polyester stretch to help you determine which one is best for your needs.

Prince Polyester

Matte in appearance, Prince Polyester offers great flexibility and breathability. It’s often used to make form-fitting items like active wear leggings as well as dancewear, making it perfect for those who are looking for a fabric that can flex and move with them.

Jordan Polyester

Known as a waterproof and wind-resistant fabric, Jordan Polyester is a special type of warp-knit fabric that offers superior stretch and flexibility. It’s often used to make outdoor clothing items like rain jackets and waterproof trousers.

Dispo Polyester

While it stretches less than Jordan Polyester, Dispo Polyester is still a great option if you’re looking for an extra layer of comfort in your clothing items. This polyester fabric can also resist water and wrinkles, making it ideal for active wear such as joggers and shorts.

Bonding Polyester

Often used for children’s winter wear, Bonding Polyester is a high-stretch fabric that provides excellent warmth and comfort. It’s soft to the touch and also offers resistance against water and fading.

Trilobal Polyester

While it’s less flexible and elastic than other polyester fabrics, Trilobal Polyester is a great choice if you’re looking for something that looks like silk but offers more durability. It has this eye-catching shine, so buyers often use it for dressy clothing items like blouses, skirts, and dresses.

File Polyester

Known for its resistance to water, wind, and fading, File Polyester is the perfect fabric for items intended for outdoor use. However, it’s not as stretchy as other polyester fabrics, so it’s not ideal for fitness apparel or clothing items that need to move with the wearer.

Taffeta Polyester

Despite not being as stretchy as other polyester fabrics, Taffeta Polyester is often used to create outdoor equipment and accessories like backpacks, tents, and sleeping bags. It’s also a great choice for cold-weather wardrobes because of its thermal insulation.

Memory Polyester

As the name imply, Memory Polyester creases and wrinkles without returning to its original form completely on its own. It also has low elasticity, which makes it a great choice for items like suits and blazers.
