What is sandwich mesh introduced by sandwich mesh manufacturer
Sandwich mesh is a double needle bed warp knitted mesh, which is composed of mesh surface, connecting monofilament and flat cloth bottom. Because of the three-dimensional mesh structure, like western sandwiches and hamburgers, it is called sandwich mesh. The following sandwich mesh manufacturer Changshu Dafa Warp Knitting Co., Ltd. will talk to you about what sandwich mesh is:
The name sandwich mesh comes from warp knitted fabric. Warp and weft yarns are different. The cycle is formed in the vertical direction or warp direction, and adjacent yarns are sleeved into each other. Like a loom, all the yarn is wound around the beam. In the beam below and above the weaving area, all the yarn is fed into the weaving area. In the process of socket, each yarn is controlled by a single needle. However, the guide rod controls the position of the yarn and each round needle may change. You can use jacquard mechanism to realize needle control to produce complex patterns of warp knitted fabrics. From the process point of view, the position between warp knitting yarn supply device and parallel yarn is sleeved with each other, which is sometimes called warp knitting machine.
Fundamentally speaking, the production and processing system of warp knitted plain fabric. The fabric has straight sides, which makes the production speed faster and the output greater. The classification of warp knitted fabrics can be based on the use of equipment and the characteristics of fabrics. The main types are: warp knitted fabrics, warp knitted fabrics, Milan are very simple, and the most common are tricoto and Raschel.
Warp knitted fabric has certain elongation and tensile properties, although its value is lower than that of weft knitted fabric. The factors affecting the tensile properties of fabrics include: fabric structure (such as single crown, double comb bar warp knitting, Raschel fabric); fabric tightness (the tighter the fabric, the lower its tensile properties); finishing machine that can give the fabric good dimensional stability); number (the number of stitches per unit width); and yarn type (e.g. elastic core spun yarn, less elastic or no fancy yarn, with better dimensional stability of single yarn or yarn).
Increase fabric strength: use high-strength fiber yarn, balance structure yarn, and use high-strength yarn with high and thin frame number. In addition, using different fiber strand combinations and changing the coil spacing will affect the strength of the fabric.
