1. Fabric density
Needle gauge refers to the distance between adjacent needles on the needle bed of the warp knitting machine. The smaller the needle gauge, the more needles per unit length. In the knitting process, this means that a finer fabric can be woven. For example, when a double-needle bed Raschel warp knitting machine with a smaller needle gauge is used for knitting, the warp yarns can be interwoven more tightly, thereby increasing the density of the fabric. This high-density fabric usually has better wind resistance, warmth retention and durability. For some application scenarios that require good protective performance, such as outdoor clothing, industrial fabrics, etc., high-density fabrics woven with a smaller needle gauge can better meet the requirements.
On the contrary, a larger needle gauge will reduce the density of the fabric. This fabric is relatively loose and has good breathability and softness. When making summer clothing, curtains and other products, fabrics woven with a larger needle gauge can provide a comfortable wearing or use experience.
2. Fabric appearance and feel
Needle gauge has a significant effect on the appearance of the fabric. A smaller needle gauge can make the surface of the fabric smoother and more delicate. Because the needle spacing is small, the coils formed are more compact and regular, the texture of the fabric surface is more delicate, and it has a silk-like luster and texture. This makes the fabric look more upscale and suitable for making some products with high requirements for appearance quality, such as high-end underwear, fashion fabrics, etc.
A larger needle gauge will make the coils on the fabric surface relatively large and the texture more obvious. This kind of fabric usually feels more fluffy and thick. For example, when weaving products such as blankets or sofa covers, a larger needle gauge can create a soft and comfortable touch, and its obvious texture can also increase the decorativeness of the fabric.
3. Fabric elasticity and tensile properties
Needle gauge also affects the elasticity of the fabric. Generally speaking, fabrics woven with smaller needle gauges have relatively less elasticity. This is because smaller needle gauges make the fabric structure tight and the movable space between the yarns is smaller. When stretched by external force, the yarns are difficult to move freely, so the elastic deformation range of the fabric is narrow. This kind of fabric is more suitable in some applications that need to maintain a stable shape, such as geotextiles for construction.
Fabrics with larger needle gauges have better elasticity. Due to its relatively loose structure, there is more space between the yarns to accommodate stretching, so when stretched by external force, the fabric can produce a large elastic deformation. When making products that require good elasticity, such as sportswear, fabrics knitted by double needle bed raschel warp knitting machines with larger needle gauges are more advantageous.
