Determination of total spun yarn production
The spinning process is long, and spinning fibers into yarn requires a series of processes. If the production of one process is out of sync, it will affect the normal progress of the entire production and even affect the completion of the production plan. Therefore, it is particularly important to ensure the balance of production and supply between each process and do a good job in production scheduling. When scheduling production, it is necessary to first calculate the total output of spun yarn, then select process parameters such as machine draft multiple and semi-finished product linear density, calculate the output of a single machine and the output of semi-finished products in each process, and then determine the number of machines required. 1. Determination of the total output of spinning yarn The balanced production and supply of the spinning process is to calculate the spinning production volume with the spinning workshop as the center, and then balance it at both ends (i.e., the pre-spinning workshops and the twisting workshop). Because the spinning workshop directly determines the production capacity of the spinning factory, the production of each pre-spinning workshop must meet the requirements of spinning production, and the production of the finishing workshop (simplification, combining, twisting, shaking, and finishing) must meet the purpose of spinning and its finishing. Require. The production volume of spun yarn depends on market demand and the production scale of the fabric factory (total number of spindles of spun yarn). Fabric joint factories should calculate the production volume of spun yarn based on the amount of yarn used for their own use and the amount of yarn sold. Balanced production and supply must be calculated by category. The calculated spinning production volume often refers to the production volume in one hour. Therefore, the spun yarn production volume required by the spinning workshop per hour should be calculated based on the spinning yarn varieties, total yarn volume and delivery time specified by the customer.
