Degree of Exhaustion of the dye bath on to the fibre that is directly connected to the substantivity should really be maximized /optimized . The migration of the dye inside the substrate through the key exhaustion phase ought to be maximized. Efficiency of reaction of the exhausted dye to the fibre need to be maximized through fixation phase.

Spandex fibers have great elasticity but poor strength and poor hygroscopicity. The invention belongs to the technical field of textile printing and dyeing, and especially relates to a strategy for dyeing cationic dyeable polyester/polyester/nylon/spandex fabric. It is crucial to set the tie dye for many hours to get the brightest colors doable.

Space dyeing is carried out by two strategies namely, Knit-de-knit approach and OPI space -dye applicator approach. In knit-de-knit strategy, the knitted fabric is dyed and de-knitted, which benefits in appearance of alternating dyed and un-dyed spaces. In OPI space-dye applicator system, the yarns are allowed to pass by way of space dye baths at really high speed which outcomes in intermittent dyeing.

Then I wipe them more than with a cloth to take away most of the moisture and leave on the draining rack for a little though. After an hour or so, I transfer them onto a windowsill.

This covalent bond is formed among the reactive group and terminal –OH group of cellulosic fibre and wool fiber or involving reactive group and terminal -NH2 group of polyamide polymer. The strength of this covalent bond is far more than ionic bond, hydrogen bond and Vander Waal’s force of attraction. Thus the reactive group becomes an integral element of the fibre. You can apply the fiber reactive dyeing method continue reading this.. to a large wide variety of things, such as cotton, and it’s some thing you can do oneself at house.
