真假羽绒服如何识别？怎样选一件合适的羽绒服？专家详解

Core Viewpoint - The article highlights the rising concern over low-priced down jackets filled with inferior materials, particularly "flying silk," which misleads consumers regarding the quality and warmth of the products [1][2]. Group 1: Consumer Complaints - Numerous complaints have emerged on social media and consumer platforms regarding down jackets that do not meet quality standards, with users reporting that the jackets contain "flying silk" instead of genuine down [1][2]. - A consumer named Wang Xin reported that her down jacket, advertised as containing 90% white duck down, was filled with short strands of material that did not provide warmth [1][2]. - Another consumer, Chen Xi, experienced similar issues with a jacket claimed to be 100% down, which revealed strands of inferior filling after washing [2]. Group 2: Understanding "Flying Silk" - "Flying silk" is defined as single strands that fall off from down or feather materials, which do not provide adequate insulation [3]. - Genuine down consists of down clusters that trap still air, creating an effective thermal barrier, while "flying silk" lacks this property [3][4]. Group 3: Standards and Regulations - The national standard for down jackets, effective from April 2022, mandates that down content must be at least 50% and can go up to 95%, with specific labeling requirements [3][4]. - The classification of down jackets is based on the percentage of down clusters, with increments of 5% [4]. Group 4: Choosing Quality Down Jackets - Key factors for selecting a quality down jacket include down content, fill power, and the fit of the jacket [5]. - Higher down content correlates with better insulation, while the fill power indicates the thickness and warmth of the jacket [5]. - The fit of the jacket is also crucial; a well-fitted jacket should allow for adequate air trapping without being too tight or too loose [5].
