Keywords: Nylon woven, knitted fabric, dyeing Nylon Knitted nylon can be used in acidic, neutral, activity, dispersion dyes, generally under acidic conditions; cotton composition with the activity, reduction, sulfide, sulfide reduction and other dyes, generally carried out under alkaline conditions, two different processes. Direct Dyes wilt dark shade, fastness is poor, generally do not. As the different dyeing, staining generally use: bath, including acid / 2 bath vat dyes, acid / reactive two bath, acid / sulfur dyes 2 bath, disperse / reactive dyes 2 bath, neutral / Reactive two bath, neutral / Dyes: bath, etc., subject to the specific methods required to determine the variety and color do not. In order to obtain pure Nylon Knitted full of dyeing effect, the dye used on cotton or Jin to prevent dyeing with each other to reduce another fiber staining. Nylon Knitted dyeing process: pre-treatment of cotton fabrics dyed → → → water washing → dehydration washing dyed nylon → → (solid color) → washing with acid / 2 bath dyeing of reactive dyes, for example, dyeing and processes for example prescription as follows. Dyeing cotton components: X type reactive dyes x% salt 5-30g / L sodium carbonate 3-15g / L Liquor ratio 1:20 Temperature 30-40 ℃ time 30-40min dyed nylon components: acid dye leveling agent y% 1 -2g / L acetic acid (98%) 0.5mL / L bath temperature of 95-100 ℃ than the 1:20 time 30-40min This carried over: http://database.texnet.com.cn/db-technology/detail- -1380.html
