Down jacket fabric is a functional fabric, and its functional requirements are higher than that of regular winter clothing. It must not only have basic functions such as warmth, anti-drilling, and windproof, but also need to have a good waterproof function to protect the inner layer of thermal insulation filling down from getting wet.
In actual production, the fabric and base fabric of down jackets are usually made of high-density fabrics to prevent down-drilling, and for high-density fabrics, their waterproof performance is the sameFiber type, fabric structure, fabric surface morphology and finishing methodRelated: The tighter the fabric, the greater the tightness of the tissue structure, the neater the arrangement between the yarns, the greater the waterproof performance of the fabric surface, if you want to further improve the waterproof performance of down jacket fabrics, you can use down jacket fabricsWater and oil repellentThrough the three-proof finishing process of the fabric, the fabric is endowed with water-repellent, oil-repellent and dirt-repellent functions in one step, so as to improve the functionality and practicability of the down jacket.
A garment manufacturer from Zhejiang approached the Texnology technical team, which already had a batch in the factoryLightweight, high-density 100% polyester pongee fabricIt is planned to be used to develop three-proof down jacket fabrics, and the customer provided us with fabric samples with clear requirementsC6 water and oil repellent was used to improve the water and oil repellent effect of the fabric sample to level 4 or above。In order to ensure the comfort of the fabric, the texnology technical team chose itTexnology FCB0582 and Texnology FCB0622 with excellent rugged performance and no impact on the breathability and feel of the fabricCarry out the three-proof finishing test.

2. Test results and conclusions
The test results are for reference only and are determined according to the actual production!
In process formulations 1-4, Texnology FCB0582 and Texnology FCB0622 C6Water and oil repellentwaterproof and oil-repellent propertiesIt can reach level 4 or above, and at the same time, it has no adverse effect on the feel and breathability of the finished fabric.
In the three-proof finishing process of down jacket fabrics, Texnology FCB0582 and Texnology FCB0622It shows excellent oil repellent performance at a low concentration of 4%, and the oil repellent level can reach 6Far exceeding the customer's expectations, the customer has now purchased the Texnology FCB0582 and put it into development and production.
