Study and Analysis on the Function and Material Properties of Baby Nappy

How to make qualified baby nappy products, we must first analyze and test the relevant data of the products. The three most important tests are comfort, functionality and material properties. Only through market research, combining the concerns of consumers with research and producing in this direction can we pass the market test. Next, take an experiment as an example to analyze the measured functionality and material properties.

Functional test of baby nappy

The functional test results of baby nappy show that the hydrostatic pressure resistance of the back materials of the six products are: 1#pe film, 2# composite breathable cotton soft bottom film, 6# non-woven fabric / PE film composite, 3# non-woven fabric / PE film composite, 5#pe perforated film and 4# silk breathable bottom film. The gram weight of the back layer is positively correlated with the hydrostatic pressure resistance of the back layer, and the pore diameter of the back layer is negatively correlated with the hydrostatic pressure resistance of the back layer. At the same time, the weight of the back layer has a more significant impact on the hydrostatic pressure resistance of the back layer. 6 kinds of baby nappy elastic waist tensile properties from excellent to bad in turn are: 5# spandex silk elastic cloth, 2# elastic elastic waistline, 3# elastic non-woven fabric, 1# elastic rubber composite material, 6t#PU foam material, 4# elastic film.

 

Comprehensive analysis of material properties of baby nappy

The comprehensive analysis results show that the correlation between each performance and comprehensive satisfaction is as follows: air permeability, permeability, liquid absorption, leak proof performance and elasticity. Air permeability has the most significant effect on the comprehensive satisfaction of baby nappy. The best comfort performance of the six products is 5# (the material composition is hot air nonwovens / hot air nonwovens / pulp, super absorbent resin / PE perforated film), and the best functional performance is 1# (the material composition is cotton soft nonwovens / hot air nonwovens / pulp, super absorbent resin and PE film). 5# the comprehensive performance is the best, followed by 6# (the material composition is hot-air nonwovens / hot-air nonwovens / fluff pulp, super absorbent resin / PE film nonwoven composite) and 2# (the material composition is hot-rolled nonwovens / super absorbent resin / composite breathable cotton flexible base film), and the worst is 4# (the material composition is hot-rolled nonwovens / absorbent paper / silk base film).

 

Finally, based on the research on the properties of baby nappy materials, a material search system is established by using computer graphics software and fineport software, so that R & D personnel can intuitively understand the properties of different levels of materials and provide reference for their design; At the same time, the establishment of the search system is also convenient for storing data and information. The combination of computer technology and baby nappy design and development makes the product more efficient and convenient in the process of R & D.
