Whether you’re trying to find the best fabric for your next project or are in the market for a new piece, there are some features to look for when selecting a stretch spandex fabric. From its high tensile strength to its high heat stability, there are several things to consider when choosing a material.
Two-way stretch vs. Four-way stretch
Choosing between 2-way stretch vs. 4-way stretch spandex fabric may seem daunting. But there are a few things to consider.
Its stretch capabilities are critical in determining which fabric to choose. If you are making tight-fitting clothing, you will want to invest in a material with a bit of stretch. It will help keep your limbs from getting in the way of your movement.
For instance, select a pair of 4-way stretch pants if you want to manufacture a pair of jeans. It will allow you to bend easily and get a lasting fit. You will also have a couple of pants that stretch with your body as you change shape and size.
The orientation of the stretch is another crucial consideration. For example, if you make a pair of pants, it will make sense to have more space along the sides and less length. However, if you’re making a skirt, choose a fabric with a more significant stretch along the length.
High heat stability
Generally, fabrics made from stretch spandex fabric are stable at high temperatures, but this depends on the fabric’s structure and construction. During the manufacturing process, tension must be kept to a minimum since it can distort the fabric structure and deform the design.
Spandex fabric is a synthetic fiber commonly used in clothing. It is often interwoven with cotton or polyester. It can elongate up to eight times its original size.
Several different manufacturing methods produce spandex fabric. Some of the most common are solution dry spinning and melt extrusion. Solution dry spinning accounts for more than 90 percent of the world’s supply of spandex.
The production process includes forming a prepolymer with monomers and diamine acid. The prepolymer is used in the remainder of the spandex fabric production process.
In this process, the fiber is spun into strands of various sizes using pressurized air. It is done in a cylindrical spinning cell. The filaments are then exposed to a heated solvent gas and solidified in a mill.
High tensile strength
The tensile strength of stretch spandex fabric is affected by several factors. The elastane content is the first consideration. It improves the fabric’s capacity to stretch.
As the elastane content increases, the fabric structure becomes compact. It reduces flexural rigidity. Lastly, the elastane content influences air permeability.
The tensile strength of stretch spandex can be determined by calculating the elongation percentage at the break. It is measured in Newton. The breaking strength is the load required to break the specimen.
Stretch spandex fabric can be obtained by adding spandex to cotton yarn. Cotton-polyester blended spun yarns were used to improve the material’s stretchability.
Five samples were collected from the warp and weft directions to determine the mechanical properties of the fabrics. They were then subjected to ASTM D3107-07 test methods. These tests were performed on a universal tensile strength tester. The clamp speed was 300mm/min, and pretension was applied at 1%.
Resistant to solvent exposure
Spandex fabric has no significant impact on the environment compared to other synthetic materials. However, certain synthetic materials are manufactured from non-renewable resources, and their concentration in the finished goods affects their appearance.
Spandex is an artificial elastic fiber that is used in high-performance garments. The material is made by reacting glycol with a diisocyanate monomer. It is commonly used in swimwear, lingerie, and fitness apparel.
Spandex fabrics are soft to the touch and maintain their silhouette after repeated stretching. This property is essential for swimwear, sports bras, and other garments that require a good fit. However, this fabric can be stained by water, sweat, or other substances and may require stain removal.
Spandex fibers are easy to dye. Acid dyes are commonly used to dye spandex fibers. However, using high temperatures on damaged Spandex fabric is not recommended. It is because it can decrease the elasticity of the material.
Spandex fabrics should be treated in a cool room to avoid exposure to temperatures above 110 degrees. Overheating can weaken the material and may cause yellowing.
Life hacks to sew
Using a sewing machine to sew stretchy fabric can be tricky. Luckily, there are some foolproof methods to achieve the same results as a couture designer without the cost and pain. The first step is to choose a machine with a needle specifically designed to handle the task. Then, the trick is to get the engine to run the right stitches at the right time. It will ensure that you avoid getting caught in dog hairs. The most incredible thing is that you can relax and take your time wearing your new spandex outfit.
The most challenging part of sewing a stretchy fabric is the sheer quantity of material. You’ll need to make sure you use the correct thread for the suitable fabric and take advantage of the machine’s ability to stitch multiple stitches simultaneously. Once you’ve found the perfect match, you’ll be ready to tackle the task. It can be tedious, but it’s well worth the effort. Once you’ve finished, you’ll be prepared to wear a new dress or suit.
