Knitted fleece is one of the most popular fabrics in the world. It is used in sweatshirts, pullovers and active wear as it is cheap, soft and smooth and is perfect for screen printing or embroidery. Almost everyone has at least one item of knitted fabric in their closet, but few of us have thought much about how it actually is made.
Even though knit fleece appears to be simple, it is by no means easy considering the manufacturing process and the many factors responsible for high quality. Not only have many manufacturers changed their knitting techniques to produce better and higher quality products, they have also added "extras" to the garment, such as ribbed Lycra and decorative stitching.
When the cotton comes to the factory
The process starts with cotton bales being laid down so that the cotton can be mixed together. The cotton is opened and then filtered; Remove foreign matter and process the cotton into more even strands. This is the step of mixing staple fibers into a mold whose mass can be reduced and each twisted into a spun yarn. Next, the cotton goes through a drawing process that increases the length per unit weight of the strands. Then, depending on the spinning system used to make the yarn, the cotton has to undergo various other processes.
There are three spinning systems that produce the yarn used in nonwoven. Open-end spinning, ring spinning and air spinning. Open-end spinning is popular because it is less expensive. The disadvantage is that fabric made from open yarn tends to be rougher than the fabric made from other processes has a harder feel. Ring-spun products are softer and have a nicer hand. Air-jet yarns are becoming more and more popular because air-jet yarns are less hairy than their counterparts. This greatly reduces the pilling of fabrics. ( pilling is caused when cotton fibers come loose on a fabric and hang on fibers that stick out from the surface of that fabric. If the loose fibers do not break off, they will form a pill.) Air-spun yarns are only used in cotton / polyester blends, however.
Knitting the yarn
The knitting of nonwoven fabric takes place at one four lanes Knitting machine. The fleece can consist of two or three ends. The difference between the two is the number of yarns knitted into the fabric. High-end sweat is usually three-sided fleece This means that the mill uses a top yarn, a ground yarn and a twine that are interwoven and naps. Three-end fleece is considered to be more stable and durable because three yarns are used in the knitting process, not two. Fleece with two ends does not use the twine when knitting and therefore does not have as smooth a surface as three ends. For a nonwoven product having two ends, the thickness is less than for a three-ended product.
After knitting, the greige or unfinished tissue is rolled onto large rolls. These rolls are stacked together for wet processing. At this time, excess oil, waxes and dirt are usually sucked out. The fabric is then stabilized and prepared either for bleaching (for white fleece) or for dyeing. Typically, the body and the rib tissue are bleached and colored together to assure color compatibility. The fabric content and the color determine how long the fabric stays in the dyeing vats. At the end of the dyeing or bleaching process, the fabric is rinsed to remove excess dye, and then passes through an extractor that functions like an old-fashioned washing machine in which water is squeezed off under a continuous roll. Fabric softeners can be added at this point.
The fabric is then turned over to prepare it for nap. The nap machine is a big drum with rollers on the outside. The wire bristles on these rollers alternate between straight and curved bristles. Just called wires traveler Move the fabric around the drum. The curved bristles actually nibble the nonwoven by grabbing and breaking the loops, creating the fluff on the underside of the fabric.
After the nap, the fabric is turned outwards with the right side calendered or compacted to reduce shrinkage. calendar is a process of spreading the fabric to the desired width and squeezing between metal rolls with steam present to stabilize the fabric.
While compression The fabric is fed into a heated machine to compact or narrow the loops in the fabric. Basically, the fabric gets into the compact chamber faster than it comes out so that the fabric is pushed together. An additional benefit of compaction is that it softens the fabric.
Once the fabric reaches this stage, it can be cut and sewn into the individually embroidered sweatshirts, sweatpants and sweaters we wear every day. If you know a little more about the knitting fleece process itself, you may have a better understanding of how to buy the garments made from them.
