Core spun sewing threads are a great option for creating t-shirts, polo-shirts and more apparel. They offer the look of cotton threads but with superior strength and durability.They are also ideal for use on denim fabrics as they decrease the number of broken stitches during hems and seams, and they can withstand heavy washes.Sewing threads must be able to pass through the sewing machine without breaking or becoming distorted during stitching. This is important for quality seams in finished garments.Sewability is determined by factors such as tensile strength, elongation, color fastness and fineness. In addition, thread must have sufficient surface smoothness to avoid clogging needle eyes and have good lubrication to minimize friction between the needle and fabric.It is specially designed for premium water-resistant outdoor wear and workwear. It is also available in a range of colors for high-quality seams. It is ideal for a variety of materials and fabrics, and offers excellent abrasion resistance. It is also resistant to chemicals and flame retardants.
The durability of core spun sewing threads is dependent on many factors. The thread’s tensile strength and elongation at break determine its ability to resist abrasion during sewing. The uniform thickness of the thread contributes to its ability to pass smoothly through the eye of the needle, minimizing friction and jamming.The quality of the cotton covering is also important. A high degree of mercerization enhances the color of the thread and improves its resistance to abrasion.Lastly, the thread must be able to withstand the various agents it is exposed to during production and use. Both have polyester cores wrapped with cotton, resulting in a durable and strong sewing thread. These brands are also lubricated for easy sewing.The threads used in the production of jeans are usually core spun and have a high tensile strength. They are also able to withstand repeated stretching and stress in the sewing process. These threads can be produced using a single-ply yarn or multi-ply yarn, depending on the application.
Moreover, the sheaths of these threads hardly absorb moisture and are therefore ideal for use in outdoor equipment. The sheaths also swell slightly when they come into contact with water, which helps to seal the seam holes and makes the thread waterproof.A high-quality core-spun polyester thread should be finished with lubricants that can protect the thread from friction and prevent it from breaking when sewing through thicker fabrics. The lubrication should be inexpensive and non-toxic.There are different types of thread for sewing, and each has its own strengths. Although matching thread fiber to fabric fiber seems logical, it’s more practical to choose a thread based on colorfastness and other characteristics that will enhance your sewing project.Core spun yarns are two-component threads with a core and sheath covering. The sheath is made from polyester staple fibres, and the core can be a continuous filament or a multi-filament.
The sheath is dyed to produce a wide range of colors, suitable for sewing a variety of fabrics. These yarns have high tenacity and are recommended for use with automatic multi-directional sewing machines. They also have higher seam strength and chemical resistance than spun threads. This allows you to use smaller thread sizes, which minimizes seam puckering and needle cutting.When comparing threads, look for the weight and fiber. The higher the number, the heavier/thicker the thread.There are also different coatings to choose from. Mercerized thread is coated with a wax or resin, which makes it stronger and gives it a nice luster. It's also resistant to mildew and can handle more stress than unmercerized thread.There are two types of core spun sewing threads: cotton wrapped poly core (D-Core) or a poly wrapped polyester core (Epic or Perma Core). Both can be used with either a mercerized or unmercerized needle. Core spun threads are treated with lubricants after heat setting to prevent it from clogging the needle eye and providing smooth sewing performance. They are available in a wide variety of colors and sizes.
