Description
Technical Field

Background
Nonwoven fabrics, also known as nonwovens, are composed of oriented or random fibers. The non-woven fabric has the characteristics of light weight, environmental protection, moisture resistance, ventilation, softness and the like, and is widely applied to the field of packaging, in particular to packaging materials of foods and home furnishings. When used as a packaging material, the nonwoven fabric is required to have good breathability and to be isolated to the maximum extent from the outside. If a hot air nonwoven fabric, a water jet nonwoven fabric or a needle punched nonwoven fabric is used, although the air permeability is good, the air gap is large, and impurities such as dust in the air easily enter the package bag, which affects the packaged articles. The melt-blown non-woven fabric can be used as a packaging material, and the melt-blown non-woven fabric has a smooth surface and is not easy to fuzzing due to the production process, so that the influence of factors such as fuzzing and the like on packaged articles can be avoided when the melt-blown non-woven fabric is used as packaging. When the gram weight of the melt-blown nonwoven fabric is high, the air permeability is poor, and when the gram weight is low, the air permeability is excellent, but the strength is reduced. When the composite non-woven fabric is used as a packaging material, the adhesive is adopted during the compounding, so that the packaged article is influenced.
How to prepare a composite non-woven fabric which has good strength, does not have hair falling on the surface and does not use an adhesive, and the composite non-woven fabric is used as a food packaging material and is a problem to be solved.
