How to effectively and quickly apply nonwoven fabric rollers to the knitting industry

Non-woven fabric rollers are also called rollers, which refer to the general name of the cylindrical parts that can be rolled on the machine. After the roller was used for about 15 d, it broke by itself at a position about 260mm away from the shaft head. The noise was loud during the break and the broken shaft head collapsed nearly 1 m. The roller is a variable-section shaft with a maximum diameter of 545mm, a total length of 2 296 mm, and a material grade of 40Cr. It has undergone forging, rough turning, quenching and tempering heat treatment and finishing processes. Non-woven fabric rolls are used in the knitting industry. In this process, the Roberto rolls with high-efficiency rolling liquid are used to replace the rubber rolls of the first rolling car. The rubber rollers of the second rolling car can increase the squeezing pressure, which can ensure the first The liquid-carrying rate of the fabric in the first tank is reduced, and the second tank fabric can absorb the auxiliary agent. Richard Hough is convinced that the use of ROBERTO rollers can significantly improve the product quality and production efficiency of chemical additives in the wet-to-wet process on the knitted fabric production line. The use of ROBERTO rollers can bring significant technical and economic benefits to customers. Better product quality, faster production speed and a lot of energy saving are the three magic weapons for the application of ROBERTO nonwoven rolls in the knitting industry. According to the statistical data of the actual application of the Brazilian textile industry, it is confirmed that in the wet processing of knitted fabrics, the ROBERTO high-efficiency squeeze roller applied to the tenter setting machine can reduce the liquid rate of the fabric by 25%. When the rubber roller is used in the first tank, if the fabric has a water content of 80% after the first treatment, if the process is set to absorb 20% of the auxiliary agent, the fabric is squeezed for the second time before entering the setting machine The liquid entrainment rate needs to be 100%. After using the ROBERTO roller in the first tank, if the fabric has a water-carrying rate of 60% after the first treatment, the process is set to absorb 20% of the auxiliary agent, and the fabric's liquid-carrying rate for the second squeeze before entering the setting machine It can be reduced to 80%. The final liquid rate of the fabric using ROBERTO roller can be reduced by 20%. Richard Howe's test proved that if two ROBERTO rollers are used on the first rolling mill, the liquid entrainment rate can be reduced by 5%, and the fabric feels softer. The benefit of the ROBERTO roller is that the length of the dryer can be reduced by 25%, and the fabric can still absorb the same additives. Customers can choose to increase the speed of the setting machine or save costs by saving drying energy. After the use of ROBERTO rolls in the first rolling car, the quality of the fabric has been improved. Compared with the use of ROBERTO rollers and rubber rollers, ROBERTO rollers can bring a softer fabric feel. It can also bring better finishing effects and less damage to the fabric structure.
