Problems solved by technology

The modified amino silicone oil in the prior art improves the yellowing of the fabric and improves the air permeability by introducing polyether or epoxy groups, but the softness decreases accordingly, making it difficult to improve the comfort of the fabric as a whole. Denaturation and comfort determine the added value of fabric products in the market. At the same time, these finishing auxiliaries also generally have the following deficiencies: easy to break emulsion and float oil during transportation, easy to stick to rollers during use, easy to produce silicone oil spots on processed fabrics, not It is beneficial to back-dyeing, therefore, there are problems and deficiencies in the prior art that the softness and air permeability of fabric products cannot be achieved at the same time, and the added value of the market is difficult to improve
