What are the factors that affect the air permeability of textiles by waterproofing agents? Next, 1,3,5,7-Tetramethylcyclotetrasiloxane Manufacturer will explain in detail.
Elements of the waterproofing agent textile itself
- Fabric structure: Under the same sorting density and tightness, the order of air permeability is plain weave <twill <satin weave <porous structure.
- Fiber shape and yarn structure: When the linear density of warp and weft yarns is the same as the sorting density of warp yarns, the special-shaped fiber fabric is better than the circular cross-section fiber fabric, and the single fiber thicker than the single fiber has better air permeability.
- Post-carding production and processing of textiles: textile printing and dyeing carding, the structure of the textile is tighter, and the air permeability is reduced; reduce the disposal, the textile fiber becomes thinner, the porosity between fibers and yarns increases, and the air permeability becomes larger.
