Production process of garment factory According to the detailed short code/less phenomenon of the invoice, you should personally participate in the inventory and confirm the delivery date of the large goods and the inspection of the quantity inventory and appearance and internal quality after the fabric enters the factory,And confirm that the production requirements can be put into production.Before mass production, technical preparation should be carried out first,Including process List, model formulation and sample garment production,The sample clothes can enter a production process after being confirmed by the customer.The fabric is cut and stitched into semi-finished products,After some woven fabrics are made into semi-finished products,According to special process requirements,After finishing and processing,For example, ready-made clothes washing, ready-made clothes washing, wrinkle effect processing, etc,Finally, through the keyhole nailing auxiliary process and ir

Joule's law application: After cutting the electric heating wire of the household electric furnace to a small section Hello!The electric furnace is a pure resistance circuit,All electric energy is converted into 0 to 4 and 6 energy.W = I ^ 2 * R * t = U ^ 0.If R * t increases the resistance of an electric heating wire,W = U ^ 2.R * t,Then gR increases,W will reduce the parallel resistance of g on the electric heating wire,However, the parallel connection does not affect the m series resistance on the electric heating wire,Then r by W = U ^ 1.R * t,W will reduce p, so select B to reduce h electric wire resistance,R reduces B,W will increase.Thank you!\ R2011-10-After cutting a short section of the electric wire at 8:54:46,The resistance becomes smaller,I = V/R,The current becomes larger,According to Q = I ^ 2;× Rt,The electric furnace power becomes larger.Cause the furnace or fuse to burn out.
