1、 In depth analysis of the physical properties of Lixinbu

（1） Mechanical properties

tensile strength

Lixin cloth has excellent tensile strength. Its fiber raw materials mostly use high-strength synthetic fibers such as polyester fibers, with tightly arranged molecular chains and strong intermolecular forces. In practical applications, such as making eco-friendly shopping bags, even if they are loaded with heavy objects, Lixin cloth shopping bags are not easily damaged due to tensile force; When used as a roof waterproof coating material in the field of engineering construction, it can effectively resist the tensile force caused by building settlement, thermal expansion and contraction, and ensure the integrity of the waterproof layer.

wear resistance

The wear resistance of fibers is one of the key factors for the durability of Lixin fabric. Taking the production of conveyor belts as an example, Lixinbu needs to constantly come into contact and friction with the transported items and conveyor belt wheels. Some special synthetic fibers, such as nylon fibers, are used in Lixin cloth. Their molecular structure contains amide bonds, which give the fiber surface a certain hardness and wear resistance. They can maintain their shape and performance during long-term friction, effectively resist wear, and extend the service life of the conveyor belt.

tear resistance

The weaving method has a significant impact on the tear resistance of Lixin fabric. Plain weave is a common weaving method for Lixin fabric, where warp and weft yarns are interwoven with each other, and each warp and weft yarn is alternated up and down. This tight structure gives the fabric good tear resistance. When making outdoor tent fabric, plain weave Lixin fabric can effectively resist external forces such as tree branch scratching and strong wind pulling that may cause tearing, ensuring the normal use of the tent.

（2） Chemical stability

acid and alkali resistance

In special industries such as chemical engineering, the acid and alkali resistance of materials is crucial. If Lixinbu is made of specially treated polyester fibers or other fibers with good acid and alkali resistance, it can maintain stable performance when in contact with chemical substances such as acid or alkali. For example, as a lining material for chemical transportation pipelines, it will not undergo chemical reactions due to contact with acidic or alkaline substances in chemical raw materials, avoiding problems such as corrosion and strength reduction, ensuring long-term use in complex chemical environments.

oxidation resistance

Lixin cloth products used outdoors, such as sunshade tarpaulins, are exposed to sunlight and air for a long time and face oxidation risks. Some Lixin fabrics that have been added with antioxidants during the fiber production process, or fabrics that have undergone antioxidant treatment in the later stage, can effectively resist the oxidation reaction caused by ultraviolet rays in sunlight and oxygen in the air, prevent the fabric from becoming brittle, reduce strength, maintain its softness and strength, and extend its service life.

（3） Other physical properties

breathability

Lixin fabric can generally be processed into various types of mesh fabric with good breathability. In agricultural planting, using Lixin cloth as a covering material for horticultural crops such as vegetables and flowers can ensure sufficient oxygen for crop roots, which is beneficial for crop root respiration and healthy growth; In the field of home textiles, good breathability can enhance user comfort and prevent stuffiness and dampness when used to make mattress fabrics and sofa linings.

dimensional stability

In scenarios where high dimensional accuracy is required for making clothing samples, industrial molds, and precision instrument packaging materials, the dimensional stability of Lixinbu is particularly critical. By using Lixin fabric that has undergone pre shrinking treatment or has a special fiber structure, its dimensional stability can be improved, ensuring accurate dimensions under different environmental conditions such as temperature and humidity changes, and meeting practical usage needs.

ageing resistance

In order to improve the anti-aging property of Lixinbu, anti-aging agents such as ultraviolet absorber and antioxidant are often added in the production process. These additives can absorb or neutralize harmful light and chemicals to fabrics, delaying the aging process of fabrics. Taking Lixin cloth used in outdoor billboard production as an example, Lixin cloth with good aging resistance can effectively resist wind and sun, reduce fading, hardening, cracking and other aging phenomena, and maintain the display effect and service life of billboards.
