A set of self-heating underwear has a fair value of about 167 yuan, and 300 sets correspond to a donation of over 50,000 yuan. This is not a large amount in the textile industry's charity activities, but the supply chain logic behind it deserves scrutiny. The products provided free of charge by Jifa Group are not ordinary thermal underwear but are equipped with self-heating functional fabrics, indicating that the company has mature and quickly deployable capacity in functional fiber R&D, weaving, and garment production.
Event Background
Xi County, located at the southern foot of the Lüliang Mountains in Shanxi, was a former national-level poverty-stricken county. The summer flood disaster in 2025 further weakened local residents' self-rescue capabilities. Winter warmth supplies became an urgent need. Since launching the 'Textile Light · Love Benefits Action' in 2017, the Textile Light Foundation has focused on key assistance and post-disaster aid. The collaboration with Jifa Group is a typical precise deployment of 'enterprise capacity + foundation channels'.
As a leading textile enterprise in Qingdao, Jifa Group has long specialized in knitted fabrics and functional garments, and its self-heating underwear product line is technologically advanced in the industry. The donation itself is actually a hidden but efficient product application demonstration: in the mountainous areas of Xi County with sub-zero temperatures, the actual thermal insulation effect of the self-heating fabric will be directly tested.
Industrial Impact
The competition in the self-heating underwear market has shifted from concept hype to technology implementation. China Customs data show that in 2024, the export value of functional textiles increased by 12.3% year-on-year, with the proportion of self-heating knitted underwear continuing to rise. Although the 300 sets donated by Jifa Group are limited in quantity, the usage feedback from 300 local households will become field test data for its product performance in extreme low-temperature environments.
From an industrial cluster perspective, Qingdao, as an important northern knitted garment production base, has a complete industrial chain from fiber, yarn to garment. Jifa Group's ability to quickly respond to donation needs indicates that its inventory management and flexible production system can support small-batch, multi-variety social responsibility orders. For other textile enterprises, this means that social responsibility investment is no longer just financial donation but can be transformed into opportunities for product testing, brand exposure, and market education.
For buyers, the supply chain stability of functional underwear is crucial. The raw materials for self-heating fabrics mainly rely on modified polyester fibers and far-infrared ceramic powders, with upstream suppliers concentrated in chemical fiber clusters like Shaoxing, Zhejiang, and Changle, Fujian. Jifa Group's self-sufficiency in some raw materials through proprietary technology reduces dependence on external suppliers, which is key to its rapid capacity deployment.
