[0002] Wrinkle resistance, moisture absorption and heat generation, antibacterial and anti-pilling are common test items for cashmere products, which are crucial for the comprehensive evaluation of the quality and performance of cashmere products. Among them, the wrinkle resistance test is used to determine the ability of cashmere products to recover after being subjected to external forces and the external forces are removed, so as to judge their wrinkle resistance; the moisture absorption and heat generation test focuses on whether cashmere products can generate heat after absorbing water, which is directly related to the warmth effect when wearing and using; the antibacterial test is used to detect whether cashmere products have the ability to inhibit bacterial growth, which is extremely important for maintaining the hygiene of cashmere products and personal health; the anti-pilling test is used to evaluate whether the surface of cashmere products is prone to pilling during long-term use, which affects the appearance and service life.
