Solvent scouring

Solvent Resistance. Elastomeric fibers tend to swell in certain organic solvents mbber fibers swell in hydrocarbon solvents such as hexane. Spandex fibers become highly swollen in chlorinated solvents such as tetrachloroethylene [127-18-4] (Perclene). Although the physical properties of spandex fibers return to normal after the solvent evaporates, considerable amounts of its stabilizers may have been extracted. Therefore, the development of stabilizers that are more resistant to solvent extraction has become important as solvent scouring during mill processing replaces aqueous scouring at many mills, especially in Europe (26).

Aqueous scouring is expensive in terms of water use and effluent treatment and it can cause entanglement of delicate wool fibres. Solvent scouring offers an effective alternative but it is essential that the solvent does not enter the environment. Earlier solvent-based processes included the use of perchloroethylene in which 8-18% water had been emulsified with a surfactant. Current processes are based on hexane (de Smet process), 1,1,1-...

Is a versatile emulsifier for solvents, vegetable oils, and waxes. In the leather industry, it is used as an emulsifier for tanning chemicals. Textile uses include resin bath penetrants, polymer stabilizers, solvent scour emulsifiers, and enzyme bath penetrants. It is also used in cold water scours for felted fabrics. [Pg.370]

The goods may be solvent scoured in rotary drum machine, restricting the load to 50% of the machine maximum capacity and the centrifuging time to 1 min to avoid the formation of pressure creases. Warp knitted fabrics are, in general, more stable to tension than weft knitted fabrics. [Pg.125]

In case of solvent scouring it is claimed that trichloroethylene at the boil provides a satisfactory method in a continuous open width plant of special design. [Pg.127]

Another continuous solvent scouring machine for knitted and woven fabrics is shown in Fig. 5-16. The Bruckner Solvanit continuous process is used for simultaneous scouring, cleaning and for shrinking. The cloth is transported by a patented... [Pg.145]
