EspañolWarp Knitting Fabric is an extremely flexible and durable textile material that is used for a wide variety of purposes. It is available in a range of designs and textures and is commonly used for sportswear, leisurewear and other apparel items.
Unlike weft knitting, warp knitting is an automated process that uses a machine to make loops and woven fabric structures. It can be produced in a wide range of materials, including cotton, wool, nylon and polyester.
The basic pattern of warp knitting is a loop-forming process in which parallel yarns zigzag lengthwise along the fabric. Each loop is secured to a loop of an adjacent strand from the previous row, and this interlocking pattern is known as a wale.
Each wale corresponds to the direction of warp in woven fabrics, and the number of wales is important for the rigidity and stability of a knitted fabric. The more wales a warp-knitted fabric has, the higher the strength of the finished product will be.
One of the most common patterns for warp-knitted fabrics is the tricot lap. In this pattern, the first guide bar works in a direction that creates vertical loops; the second bar works in the opposite direction and fully draws in the loops. The result is a fabric that has a smooth surface, little or no vertical stretch and high crosswise stretch.
In addition, the knitted structure is dimensionally stable in all directions. This allows for a variety of uses, such as a cardiac support device.
The fabric is also very soft and comfortable to the touch, making it popular for use in clothing and sportswear. Some of the most common warp-knitted fabrics are denim, flannel and chiffon.
These fabrics can be made in a variety of colors and designs, including stripes, solids, checks, patterns and other geometrical shapes. They are often brushed on both sides to add softness and give them a more comfortable feel.
Some of these patterns can be adapted to produce special properties such as elasticity or wicking. Examples include the satin lap (used to create a velour) and the tricot lap, which can be used for a more durable fabric.
For example, the tricot lap is sometimes combined with the raschel pattern to create a textured fabric. The raschel pattern can be used to create a terry cloth by stitching pile yarn through a backing fabric.
This type of fabric is very useful for towels and floor coverings, as it dries quickly and has a soft touch. It is also an excellent choice for children's clothes, as it is highly breathable and is washable.
In addition to these traditional fabrics, other fabric types have been developed using this technique. For example, a fabric composed of metal composite yarn/viscose yarn and bamboo polyester/polyester blended yarn was prepared on a crochet machine to achieve a double-layer structure.
This structure improved moisture management and air permeability by combining a long float at the back side with the miss-lapping structure. However, it reduced water vapor permeability slightly.
