(1)Chinese standard（GB/T 7573-2009） Weigh 3  2 + 0.05g samples, cut into 5 * 5 mm pieces, add put it into the flask containing 100ml distilled water,  shake flask, the samples will be fully soaked, put the flask on the oscillator for 2 hours ±5min, test the pH of aqueous extract (excluding fabric ) at room temperature, and repeat for 3 times, take the average values of the second and third samples as a result of the final results, accurate to 0.1. (2) EU standards (EN 1413-1998) Weigh 3 2 + 0.05g samples, cut into 5 * 5 mm small pieces, and put into flask containing 100ml of potassium chloride solution (0.1mol/L) or 100ml distilled water. and shake flask samples to make it fully soaked, put the flask on the oscillator for2 hours.  Test the pH of aqueous extract (excluding fabric ) at room temperature, and repeat for 3 times, take the average values of the second and third samples as a result of the final results, accurate to 0.1.

The choose of dye when dyeing rayon Procion HE produced by British ICI company is a kind of high-temperature reactive dyes, especially suitable exhaust dyeing. It has bright color, economical, leveling good leveling property, excellent color performance property.  In order to prevent the nylon yarn from staining with color, we can choose to add soda first, then anhydrous sodium sulphate, running in 20min, then add the activity dye, the holding time can vary with the amount of dye. The process of dyeing Nylon filament / modified polyester filament yarn 1. The addition sequence of dye  For the acid dyes used on dyeing nylon yarn, we should control the appropriate initial dyeing temperature, heating rate and dyeing time according to its diffusion, aggregation tendency and dye migration performance level. Only by thus, it can have good levelness and penetration effect. Cationic dye has good affinity with modified polyester filament. Due to its quick absorption and slow d...

The soft textile agent is the kind of soft agent with good performance and prominent effect, which is widely used. But it also has obvious defects, that is, after treated by the organic silicone, if the defects occur, the process of changing color and repairing becomes very difficult. Improper handling may cause the oil patch, mottling, even mottling occurs when we change the fabric into black color. In serious conditions. Many dyeing plants have to give up the good hand feeling of the fabric and change into the non-silicone softness agent with worse finishing effect. The result is the hand feeling will not meet the customers' requirement and be in trouble. So the solution to the re-dyeing problem after organic silicone softness finishing is significant. 1. The washing of organic silicone spot  There are different kinds of spots in the fabric. Among them, the most difficult to wash out is organic silicone spot. For those which have reacted and combined with the fabric, the po...
