Silicone oil in the textile and clothing industry is generally used as a fabric softener, lubricant, waterproof agent, finishing agent and so on.In order to meet the high-end demand of textiles, organosilicone material manufacturers are also developing products that can be used in bath with a variety of functional additives such as water repellent, flame retardant, antistatic agent, color fixing agent, and feel good silicone oil products.In addition, in order to improve the fabric performance, there are silicone products that can be used in the same bath with dyeing, silicone oil for cotton with cool feeling, silicone products that can improve the feel of the fabric, and silicone darkening agents that can give the fabric excellent darkening effect, good storage stability, do not affect the color fastness, good feel, etc.In addition to the functionalization of textiles as an additive, organosilicon products will also be used in other areas of textiles.

    But there are many kinds of textile silicone softener, the effect is also different, even the same effect on different fabrics for textile silicone softener also need to choose a right, if use undeserved, light can not reach the effect of the fabric they want, serious still can damage the fabric, so we should if choose textile silicone softener?What is the reason for the poor effect of those textile silicone softeners with the same effect?How should we solve these problems?

    In the use of textile silicone softener when a class will encounter fabric hydrophilicity decline, dark spots, light spots, alkali spots, silicone oil spots and other problems.

    The reasons for the decline of fabric hydrophilicity are generally the structure of the film and the silicone oil film after the lack of water absorption genes, and the closure of the water absorption centers such as cellulose fiber hydroxyl, carboxyl group on wool, amino group, resulting in the decline of water absorption.

    Its treatment method: anionic, non - ionic film and hydrophilic silicone oil should be selected as far as possible.

    The causes of dark stain: ① When the fabric is treated, the oil stain is not cleaned, and the color of the oil stain is darker when dyeing.(2) There is too much foam in the dyeing bath, and the mixture of foam and flower sweater and dye sticks to the fabric.③ Dark oil spots caused by flapping oil of defoaming agent.Tar in the dye VAT stuck to the fabric.⑤ The dye agglutinates into dark spots under different conditions.⑥ Too much water calcium and magnesium ions and dye in the fabric and other reasons.

    Treatment methods:

    (1) Before treatment, add oil agent for refining.② Dyeing auxiliaries are low-bubble and no-bubble auxiliaries.③ The selection of defoaming agent is not easy to drift oil varieties, add chelating agent to improve water quality, add dissolving dispersant to prevent dye agglutination.Clean the cylinder with cleaning agent in time.

    The causes of light color spots are as follows: 

    (1) Uneven pre-treatment, poor wool efficiency in some parts, certain dye resistance, with dye resistance substances.Cloth with calcium soap, magnesium soap, etc., or uneven mercerization during pre-treatment.The drying of semi-products is not uniform.③ The cloth is stained with solid such as undissolved sodium chloride powder and soda ash.4. Drizzle the dye before drying.⑤ Stains with auxiliaries after soft treatment of dyeing materials.

    Treatment method: To strengthen the pre-treatment, the selection of pre-treatment additives must not be easy to form calcium and magnesium soap, and the pre-treatment must be uniform and thorough (this is related to the selection of refining agent, penetrant, chelating dispersant, mercerizing penetrant, etc.).The powder, soda ash and so on must be well into the cylinder and the production management must be strengthened.

    Causes of alkali spots: After pre-treatment (such as bleaching, mercerization), the removal of alkali is not clean or uniform, resulting in the generation of alkali spots.

    Treatment method: The dealkalization process of the pre-treatment process must be strengthened.

    Silicone oil spot stains caused by: cloth PH value is not up to neutral, especially with alkali, resulting in silicone oil emulsion floating oil.Treatment bath water quality is too poor, the hardness is too high, silicone oil in the water >150PPM hardness is easy to drift oil.Silicone oil quality problems include poor emulsification (poor emulsifying agent selection, poor emulsifying process, emulsifying particles too large, etc.), intolerance

    Shear. Choose shear resistant, electrolyte resistant, PH resistant silicone oil, but pay attention to the use of silicone oil and the environment, can also consider choosing hydrophilic silicone oil.
