1. Testing items

Ingredient identification: It is crucial to accurately determine the proportion of silk. Silk comes from natural silk. If it is mixed with too much chemical fiber or other fibers, it will not only feel stiff, but also have poor breathability and moisture absorption, and will not be able to show the unique charm of silk.

Appearance review: Color uniformity is a key consideration. High-quality silk dresses should have pure colors, natural transitions, and no mottled colors. At the same time, defects such as skipped threads, holes, snags, and stains should be strictly checked. These minor defects can easily destroy the overall elegant style.

Physical performance verification: Tensile and tear strength determine the durability of wearing. Although silk is known for its softness, it must withstand the pulling in daily activities to prevent accidental tearing. In addition, dimensional stability is related to the fit, and the original version should be maintained after washing to avoid shrinkage and deformation.

2. Testing methods

Composition analysis: The combustion method can be used for preliminary judgment. When silk burns, it has a smell similar to burning hair, and the ashes are in a fragile powdery form. Combined with the chemical dissolution method, the dissolution characteristics of different fibers in specific chemical reagents are used to accurately lock the composition.

Appearance identification: Professional testers use their keen vision to examine every inch of the skirt from multiple angles under the standard D65 light box, without missing any minor defects to ensure that the appearance is flawless.

Physical property measurement: Use a universal material testing machine to simulate the force of the fabric during human movement and record the tensile and tear strength data. The dress is processed with a standard washing process, and the dimensions of key parts are measured before and after, and the change rate is calculated to evaluate the stability.

3. Testing standards

National standard specification: Clearly define the lower limit of silk content to ensure that consumers know the nature of the products they purchase. In terms of appearance, the color deviation is limited to a very small range, and the defect category, quantity and size upper limit are strictly stipulated. The physical performance standards are subpided according to the daily use of the dress, formal dress, etc., to adapt to different wearing needs.

International integration: Some high-end brands follow international standards and have higher requirements at the forefront of environmental protection. For example, ecological dyes are selected, the release of harmful substances is strictly controlled, the concept of sustainable fashion is implemented, and the international image of the brand is enhanced.

4. Significance of testing

Consumer welfare: Qualified silk dresses allow consumers to enjoy a silky, skin-friendly, elegant and charming wearing experience, away from quality risks, and buy with peace of mind and wear comfortably.

Merchant reputation: Strict testing is a solid shield for brand reputation, reducing return and exchange disputes, accumulating good reputation, and standing out in fierce competition.

Industry advancement: Standardized testing is like a strong east wind, helping the industry to eliminate inferior products and retain good ones, stimulate innovation vitality, and promote silk dresses to a new height of excellence and continue to write fashion legends.
