Embodiment 1
[0023] Example 1 Plasma treatment of wool knitted fabric
[0024] Process flow: wool scouring→plasma treatment
[0025] in:
[0026] 1) Wool washing: The wool knitted fabric is treated at a constant temperature of 40°C for 30 minutes in 0.5 g / L wool washing liquid at a bath ratio of 1:30. Drain lightly, dry and set aside.
[0027] 2) Plasma treatment:
[0028] Treat at 30Pa, 100W for 3min. Gas: air.
[0029] The wool knitted fabric treated by the above process has an anti-felting rate of 10.47% (untreated 17.20%), and a bursting strength of 0.276Mpa, which is 6.15% stronger than the bursting strength of 0.260Mpa after scouring.
Embodiment 2
[0030] Embodiment 2: Plasma combined with protease to treat wool knitted fabric
[0031] Process flow: wool scouring→plasma treatment→protease treatment→water washing→drying
[0032] 1) Wool washing: The wool knitted fabric is treated at a constant temperature of 40°C for 30 minutes in 0.5 g / L wool washing liquid at a bath ratio of 1:30. Drain lightly, dry and set aside.
[0033] 2) Plasma treatment:
[0034] Treat at 30Pa, 100W for 3min. Gas: air.
[0035] 3) Protease treatment:
[0036] The mass concentration of protease is 4% (o.w.f) (weight to wool), the temperature is 50° C., the time is 40 minutes, the bath ratio is 1:20, and the pH is 8.5.
[0037] 4) Washing:
[0038] Treat at 90°C for 10 minutes, and inactivate the enzyme at high temperature. Wash twice in cold water, gently absorb the water, dry at 80°C, and set aside.
[0039] The wool knitted fabric treated by the above process has an anti-felting rate of 1.79% (untreated 17.20%) and a burst...
Embodiment 3
[0040] Example 3 Plasma combined with protease and transglutaminase (TGase) to treat wool knitted fabrics
[0041] Process flow: wool scouring→plasma treatment→protease treatment→water washing→transglutaminase treatment→water washing→drying
[0042] in:
[0043] 1) Wool washing: The wool knitted fabric is treated at a constant temperature of 40°C for 30 minutes in 0.5 g / L wool washing liquid at a bath ratio of 1:30. Drain lightly, dry and set aside.
[0044] 2) Plasma treatment:
[0045] Treat at 30Pa, 100W for 3min. Gas: Air.
[0046] 3) Protease treatment:
[0047] The mass concentration of protease is 4% (o.w.f) (weight to wool), the temperature is 50° C., the time is 40 minutes, the bath ratio is 1:20, and the pH is 8.5.
[0048] 4) Washing:
[0049] Treat at 90°C for 10 minutes, and inactivate the enzyme at high temperature. Wash twice in cold water, gently absorb the water, dry at 80°C, and set aside.
[0050] 5) Transglutaminase treatment:
[0051] The mass co...
