A zipper tester is a device used to evaluate the performance and durability of zipper products, commonly used for zippers in garments, bags, shoes, and other items. It evaluates the durability, tensile strength, abrasion resistance, and reliability of zippers by simulating the opening and closing action of zippers in daily use. The zipper tester repeatedly opens and closes zippers to simulate their real-life use.

This repeated opening and closing test determines the zipper’s ability to maintain stable performance throughout its service life, including its susceptibility to snagging or chain detachment. Additionally, the zipper tester measures the force applied to the zipper during the opening and closing process to evaluate its tensile strength.

The salt spray test machine, also known as a salt fog chamber, is a device designed to test the resistance of materials and their surface treatments to salt fog corrosion. This machine evaluates the corrosion resistance of products by simulating a salty marine climate, thereby replicating harsh environmental conditions for corrosive testing.

During the test, the machine atomizes a saltwater solution and disperses it through nozzles to create a continuous salt fog, which is then sprayed onto the surface of the sample. This test accelerates the corrosion process, enabling manufacturers to estimate a product’s corrosion resistance under actual usage conditions and to make the necessary improvements.

The universal tensile tester is versatile material testing equipment used to determine the mechanical properties of materials in various testing modes, such as tensile, compression, bending, and shear. This tester can provide accurate mechanical parameters, including tensile strength, compressive strength, modulus of elasticity, and yield strength, offering a comprehensive assessment of a material’s physical properties.

A universal tensile tester typically consists of a fixed base and a moving beam, which allows a sample fixture to apply force. It can measure strain, breaking point, tensile strength, compressive strength, bending strength, and other parameters under stress, thereby assessing the material’s mechanical properties, including strength, toughness, and stiffness.

General-purpose tensile testing machines are used to test luggage or backpacks in the following applications:

– Fabrics and textiles: Measure the tensile strength and elongation of materials used in the body of a suitcase or backpack to ensure that they are able to withstand the intended load and use.
– Straps and handles: Test the durability and load-bearing capacity of straps, handles, and their attachment points.
– Zippers and fasteners: Determine the tensile strength of zippers, buckles, and other fastening devices to ensure they do not fail during normal use.
– Seams and stitching: Evaluate the strength of seams and the force required to cause sliding or breaking.

By using universal tensile testing machines that adhere to industry standards, such as those from ASTM or ISO, manufacturers can quantify and enhance the mechanical strength and flexibility of these materials and components.

The electric heating constant temperature blast drying oven is a commonly used piece of equipment in laboratories, mainly utilized for a variety of routine tests such as drying, heat treatment, baking, wax melting, and sample sterilization. Its working principle involves maintaining a uniform and constant temperature inside the chamber by using electricity as the heating source and promoting air circulation with a built-in fan, with precise control achievable through the control panel, including setting the temperature to meet experimental requirements.

In the backpack industry, the electric heating constant temperature blast drying oven is applied in several key areas:

– Material thermal stability testing: The oven is used to assess the performance of backpack fabrics and synthetic materials under high-temperature conditions.
– Adhesive and coating curing: The oven accelerates the curing process of adhesives and special coatings used in backpacks, allowing for the testing of their performance.
– Environmental simulation: The oven simulates the environmental conditions that backpacks may encounter at various temperatures to test the materials’ temperature resistance.

By employing the electric heating constant temperature blast drying oven to assess the performance of backpack materials and components, manufacturers can ensure the durability and functionality of backpacks under diverse environmental conditions.

The standard light source color box, also referred to as a color matching booth or color assessment cabinet, is a specialized device designed for color management and evaluation. Its primary function is to simulate various standard light sources, providing an environment suitable for the visual inspection and comparison of colors on diverse items.

This equipment typically comes equipped with a variety of light sources that conform to standard or benchmark conditions for visual color assessment, such as those defined by the International Organization for Standardization (ISO).

Standard light source color boxes usually include light sources like D65 (simulating daylight), TL84 (simulating store and showroom lighting), CWF (Cool White Fluorescent), F (typical household lighting), UV (ultraviolet light), and TL83, among others. The purpose of these varied light sources is to help users identify color discrepancies that might occur under different lighting conditions and to confirm color consistency, thereby ensuring controlled and managed color quality.

The use of a standard light source color matching booth in testing luggage or backpacks extends to the following areas：

Fabrics and textiles: Ensuring that the colors of fabrics used in backpacks and luggage are consistent and remain so under varying lighting conditions.
Coatings and prints: Testing the color accuracy of printed patterns or coated surfaces on luggage or backpacks.
Metal hardware: Evaluating whether the color of zippers, rings, and other metal parts matches the rest of the luggage or backpack under different lighting conditions.
