A paper diaper production mechanism

By using anti-adhesion components and sizing agents in the diaper production process, the adhesion between the elastic yarn layer and the fabric layer is reduced, solving the problem of poor heat dissipation and breathability caused by multiple fabric layers in the elastic waistband area. This achieves better breathability and heat dissipation while saving material costs.

AI Technical Summary

Technical Problem

In the current diaper production process, the use of multiple fabric layers in the elastic waistband area leads to problems with poor heat dissipation and breathability.

Method used

The system employs a fabric unwinding assembly, an elastic yarn unwinding assembly, an adhesive applicator, and a tack-reducing assembly. After adhesive application, a tack-reducing agent and a cold air jet are used to reduce the adhesion between the elastic yarn layer and the fabric layer, thereby reducing the number of fabric layers and improving breathability and heat dissipation.

Benefits of technology

Without compromising the elasticity and stretchability of the elastic waistband, it effectively improves heat dissipation and breathability, reduces the number of fabric layers used, and lowers material costs.

Abstract

The application relates to the technical field of sanitary product manufacturing, and particularly discloses a paper diaper production mechanism, which comprises a cloth layer unwinding assembly, an elastic filament unwinding assembly, a gluing piece, a first composite station and a viscosity reduction assembly; the cloth layer unwinding assembly is used for unwinding a cloth layer; the elastic filament unwinding assembly is used for unwinding an elastic filament layer; the gluing piece is arranged downstream of the cloth layer unwinding assembly and the elastic filament unwinding assembly and is used for gluing at least one of a composite surface of the cloth layer and the elastic filament layer; the first composite station is arranged downstream of the gluing piece and is used for combining the composite surface of the cloth layer and the elastic filament layer; and the viscosity reduction assembly is arranged downstream of the first composite station and is used for reducing the viscosity of the composite surface of the cloth layer and the elastic filament layer. In the scheme, after the elastic filament layer is combined with the cloth layer, the viscosity of the two can be reduced by the viscosity reduction assembly without arranging the cloth layer, so that the number of cloth layers in the elastic waist circumference area can be reduced, and the air permeability and heat dissipation of the elastic waist circumference area can be improved.
