CO2 incubators are categorized into water jacketed and air jacketed types based on heating systems. Water jacketed models use surrounding water layers for superior thermal uniformity and slower temperature loss during power outages, ideal for long-term cultures. Air jacketed incubators employ direct-heat technology for rapid temperature recovery and simpler maintenance, excelling in frequent-access applications. Both maintain critical cell growth conditions (37°C, 5% CO2, 95% humidity) for resea

This article analyzes the critical factors affecting fabric anti-pilling performance. Key influences include fiber characteristics (crimp, fineness, length), yarn properties (twist, hairiness), fabric structure (looseness), and dyeing/finishing processes (pre-treatment, pre-setting, resin application). Specific techniques like using degreasers, bath smoothing agents, and anti-pilling resins (e.g., PUNEW) are discussed, along with process parameters and considerations for maintaining fabric hand
