The super-soft pretreatment scouring agent is matched with the super-soft pretreatment process, and the treated knitted cotton cloth can exceed the effect of HS-117B treated by the conventional high-temperature process. In addition, the cloth sample treated by the method has high bursting strength and small damage to fabrics.
In summary, the scouring agent disclosed by the invention can be used for processing cotton knitting cloth samples by matching with the super-soft pretreatment process disclosed by the invention, the effect of HS-117B through conventional high-temperature process treatment can be exceeded, all cotton dyeing stages can be realized completely by utilizing solar energy, the pretreatment processing cost, energy consumption, water consumption and sewage treatment cost are greatly reduced in the processing process, dyeing and finishing engineering is changed into green new energy engineering, and the requirements of sustainable development are met.
