Production process of Nafei sanitary napkins

Raw material selection: select absorbent layer materials such as high-quality cotton fibers, soft and breathable surface materials such as non-woven fabrics or pure cotton fabrics, waterproof and breathable bottom materials such as cast film, and prepare auxiliary materials such as hot melt adhesive.

Cotton core preparation: use a pulping machine to refine the fibers to improve the fluffy and water-absorbing performance of the cotton core, and then use a compactor to shape the thickness and density of the cotton core, and then use a non-woven fabric covering machine to cover and stabilize it, and finally use a stain tester to strictly control the quality.

Molding processing: use a composite machine to "sew" each layer of material by spraying glue and hot pressing, add a guide layer with a dust-free paper laying machine as needed, and use an embossing machine to "carve" the pattern to prevent side leakage.

Addition of chips and functional layers: add nano silver, far infrared, and negative ion three-in-one functional chips, etc., to achieve the effects of promoting metabolism, improving endocrine, and antibacterial and antibacterial.

Cutting and packaging: First, the cutting machine forms the product according to the mold, and then the folding machine folds it delicately. Then, the packaging machine, nitrogen filling machine, and sealing machine work together to complete nitrogen filling, sealing, and packaging.

Quality inspection: Each batch of products will be randomly selected for chemical composition, water absorption, permeability, and other tests. Only those that meet the standards can be delivered to the market.
