The structure and characteristics of the bicomponent spunbond fibers in accordance with the different components of the composite spinning bicomponent spunbonded nonwoven fabric production line main production Four types of two-component spunbond nonwovens: core-sheath, parallel, orange and sea-island. The skin core type and parallel type are mainly introduced as follows. 2. The application of bi-component spunbond nonwovens. Due to the bi-component fiber structure, there are many cross-sectional shapes and changes. The distribution of two components makes the mono-component fiber and bi-component fiber not have the characteristics of the product application field. It can completely cover ordinary non-woven products, and has the advantages of ordinary non-woven products in some areas. For example, PE/PP leather core two-component spunbond nonwoven fabric has a softer and more comfortable feeling than traditional one-component spunbond fabrics, and has a silky smooth feel. They are very suitable for manufacturing products that come into direct contact with the human body and are commonly used as fabrics for feminine and baby hygiene products. In addition, two-component nonwovens can also be composited by ultrasonic, hot rolling and casting methods. In the process of hot rolling, the fiber has a three-dimensional self-crimping under the action of shrinkage stress, which makes the product structure fluffy and dimensionally stable. 3. Two-component spunbond nonwoven production line The production process of the two-component nonwoven production line adopts an ordinary single-component production line. The only difference is that each spinning system is equipped with two sets of raw material processing, conveying, metering, and mixing devices. Screw extruder, melt filter, melt tube, etc. Spinning pump equipment, as well as the use of two-component spinning box and two-component spinneret assembly. The two-component production line has greater application flexibility. The two components of the raw materials are different, or the raw materials use different spinning processes. The same product is a two-component non-woven fabric, and the two components use the same raw materials and the same Process, products are common non-woven fabric ingredients. Of course, the latter is not necessarily a better mode of operation, and the configuration of the two sets of equipment may not be suitable for the same raw material processing.
