Non-woven bags now play an important role in many fields such as environmentally friendly shopping and daily storage, and the fiber composition of its core material, non-woven fabric, is the key factor in determining the performance of the bag.
Non-woven fabrics are mainly composed of polyester fiber (PET) and polypropylene fiber (PP). Polyester fiber is a common synthetic fiber with excellent strength and toughness. Non-woven fabrics made of polyester fiber can withstand a certain weight and are not easy to break. This strength advantage is fully reflected when non-woven bags are used for shopping. When loaded with goods of various shapes and weights, such as fruits, daily necessities, etc., polyester fiber can ensure that the bag will not be easily torn and provide reliable load for the items.
Polypropylene fiber is also an important component of non-woven fabrics. It is characterized by light weight, which makes non-woven bags lighter as a whole and convenient for people to carry. Moreover, polypropylene fiber has good chemical stability and has strong tolerance to many chemicals. This feature is very useful in practical use. For example, when non-woven bags come into contact with some goods containing slight chemical components or under different environmental conditions, the bags will not be easily corroded or damaged.
In addition to polyester and polypropylene fibers, some high-end or special-function non-woven fabrics also add natural fibers. For example, adding cotton fibers can make non-woven fabrics more soft and hygroscopic. Such non-woven bags containing cotton fibers are more comfortable to the touch and will not cause discomfort when close to the skin. At the same time, the hygroscopicity of cotton fibers can absorb external moisture to a certain extent, so that the bag can remain relatively dry even in a humid environment.
In addition, in order to give non-woven fabrics some special properties, some functional fibers may be added. For example, adding fibers with antibacterial properties can inhibit bacterial growth, which is very important for non-woven bags that are used to hold food or need to be used for a long time. Adding flame-retardant fibers can improve the fire resistance of non-woven fabrics and increase the safety of bags in special environments.
These different fiber materials work together to form the non-woven fabrics used in non-woven bags. Their characteristics complement each other, making non-woven bags have good strength and lightness, and in some cases, they have multiple functions such as softness, antibacterial, and flame retardant, meeting people's use needs in different scenarios.
