Surface is one of the main composition material for diapers, is also very important part of the direct contact with a baby on the surface, so the surface of the comfort will directly affect the baby, non-woven factory today to tell you about two kinds of widely used diapers surface material, the difference between hot air non-woven and spun-bonded non-woven, and how to identify.
Production principle
Hot air non-woven cloth: belonging to the hot air bonding (hot rolling, hot air) non-woven cloth, hot air non-woven is in the short fiber carded, the use of drying equipment hot air through the fiber network, so that it can be heated to be bonded to form a non-woven cloth.
Spinning adhesion non-woven cloth: the polymer extrusion, stretching, forming a continuous filament, filament laid into a network, fiber network after its own adhesion, thermal bonding, chemical bonding or bonding, chemical bonding or mechanical reinforcement method, so that the fiber network into non-woven cloth.Spunbonded nonwovens are long fibers but are made from plastic chips.
Comparison of advantages and disadvantages
Hot air non-woven fabric: it has the characteristics of high fluidity, good elasticity, soft touch, good heat preservation, good air permeability and water permeability.But its strength is lower, easy to deform.
Spun-bonded non-woven cloth: it is not the use of fibers, directly from the polymer particles spinneret into a network, after heating and pressurization by rollers, excellent mechanical properties, tensile strength, breaking elongation, tear strength and other indicators are excellent, thickness is very thin, but the softness, permeability are not as good as hot wind non-woven cloth.
Therefore, the surface layer of good nappies is usually made of hot air non-woven cloth. Spinning and sticking non-woven cloth is mainly used in the manufacturing of medical care. However, many nappies businesses choose to use spinning and sticking non-woven cloth in order to save costs.
How to distinguish hot air non-woven and spun-bonded non-woven fabric?
1, feel difference
The most direct way is to touch the hot air non-woven nappies with your hands, which will feel softer and more comfortable, and the spun-bonded non-woven nappies will feel harder.
2. Pull gently
Get the nappies, gently pull the nappies surface, hot wind non-woven cloth can easily pull out the silk, if it is spun-bonded non-woven cloth is difficult to pull out the whole piece of silk.
In fact, no matter how much the baby put on diapers is not used to, uncomfortable.Mother since compare the experience that USES sanitary towel to know.So when mothers choose diapers for their babies, they must choose soft and comfortable ones, so that the baby's comfort will be improved!
