This article will deeply analyze the factory inspection and quality inspection procedures, key quality control points, and testing standards of silk scarves, providing comprehensive reference guidelines for purchasers, quality inspectors, and production enterprises.
I. Basic Knowledge of Silk Scarves and Preparations Before Inspection
(1) Characteristics and Classification of Silk Scarves
Silk scarves are clothing accessories made from natural silk fibers such as mulberry silk and oak silk. They have features such as soft luster, smooth texture, and good moisture absorption and ventilation. According to the manufacturing process, they can be classified into types such as printed, jacquard, and embroidered. According to the shape, they can be divided into rectangular, square, and triangular forms.

Review the supplier management procedures, especially the evaluation records of key raw material suppliers such as silk materials, dyes, and accessories.
Review the production process control documents and their implementation status, with a particular focus on key procedures such as refining, dyeing, printing, and finishing.
Evaluate the effectiveness of the control procedures for non-conforming products and the corrective and preventive measures.
(2) Key points of on-site production inspection
Raw material storage management: Inspection of the storage environment for silk raw materials, as well as measures for temperature and humidity control
