Innovative Silicone  Manufacturers introduced the factors that affect soft processing:

  1. Can't reach the feel
    The soft style of the soft finishing varies with different customer requirements, such as soft, smooth, fluffy, soft waxy, oily, dry and slippery, etc. Different softeners are selected according to different styles. Among the soft films, there are softener films with different structures, and their softness, bulkiness, smoothness, yellowing, and the influence on the water absorption of the fabric are all different. Among the silicone oils, the properties of modified silicone oils of different modified genes are also different, such as amino silicone oil, hydroxy silicone oil, epoxy modified silicone oil, carboxyl modified silicone oil and so on.
  2. Discoloration and yellowing
    Among the films, the cationic film has good softness, good hand feeling, easy to be adsorbed on the fabric, easy to yellow and change color, and affect the hydrophilicity. Amino silicone oil is currently the most widely used silicone oil, and amino can cause discoloration and yellowing. In emulsion polymerization, cationic surfactants such as 1227, 1831, and 1631 are sometimes used as emulsifiers. These emulsifiers can also cause yellowing. When silicone oil is emulsified, the emulsifier used is different, and its "peeling effect" is different, which will cause peeling and light color under different conditions, which is already a color change.
  3. The hydrophilicity of the fabric decreases
    Generally, problems with the structure of the film used and the lack of water absorption genes after silicone oil film formation, and the blocking of water absorption centers such as the hydroxyl groups of cellulose fibers, the carboxyl groups and amino groups on the wool, etc., cause the water absorption to decrease.

Treatment method: Anionic, non-ionic film and hydrophilic silicone oil should be used as much as possible.

  1. Dark spots
    Causes: ① The oil stains on the fabric were not cleaned during the pretreatment, and the oil stains were darker during dyeing. ②There is too much foam in the dyeing bath, and the mixture of foam, floral sweaters, dyes, etc. sticks to the fabric. ③Dark oil spots caused by floating oil of defoamer. ④The tar substance in the dyeing vat sticks to the fabric. ⑤Dye agglomerates to form dark spots under different conditions. ⑥ Water quality is caused by excessive calcium and magnesium ions combined with dyes and stained fabrics.

Treatment method: ①Add degreaser during pretreatment for scouring. ②The dyeing auxiliaries adopt low foaming and non-foaming auxiliaries. ③Select the defoamer that is not easy to float, add a chelating agent to improve water quality, and add a solubilizing dispersant to prevent dye aggregation. Use the tank cleaning agent to clean the tank and wash the tank in time.
