Embodiment 1

[0022] Embodiment 1 plasma treatment wool knitted fabric

[0023] Process flow: wool scouring→plasma treatment

[0024] in:

[0025] 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.

[0026] 2) Plasma treatment:

[0027] Treat at 30Pa, 100W for 3min. Gas: air.

[0028] 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

[0029] Embodiment 2: Plasma combined with protease to treat wool knitted fabric

[0030] Process flow: wool scouring→plasma treatment→protease treatment→water washing→drying

[0031] 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.

[0032] 2) Plasma treatment:

[0033] Treat at 30Pa, 100W for 3min. Gas: Air.

[0034] 3) Protease treatment:

[0035] 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.

[0036] 4) Washing:

[0037] 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.

[0038] The wool knitted fabric treated by the above process has an anti-felting rate of 1.79% (untreated 17.20%) and a bursting strength of ...

Embodiment 3

[0039] Example 3 Plasma combined with protease and transglutaminase (TGase) to treat wool knitted fabrics

[0040] Process flow: wool scouring→plasma treatment→protease treatment→water washing→transglutaminase treatment→water washing→drying

[0041] in:

[0042] 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.

[0043] 2) Plasma treatment:

[0044] Treat at 30Pa, 100W for 3min. Gas: air.

[0045] 3) Protease treatment:

[0046] 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=8.5.

[0047] 4) Washing:

[0048] 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.

Abstract

The invention relates to a method for anti-felting finishing of wool knitted fabrics combined with plasma and biological enzymes. The steps include: wool scouring→plasma treatment→protease treatment→water washing→transglutaminase treatment→water washing→drying. The anti-felting method for wool of the present invention enables wool knitted fabrics to reach the machine-washable standard (felting shrinkage rate is less than 2%) under the condition of ensuring strength (strength damage is less than 10%), and the finishing process has little damage to fibers, which is safe and environmentally friendly. It is an energy-saving and clean wool finishing process.

Description

technical field [0001] The invention belongs to the field of anti-felting of wool, in particular to an anti-felting finishing method of wool knitted fabrics combined with plasma and biological enzymes. Background technique [0002] When wool products are processed and washed, the oriented scales will be rubbed to cause displacement between fibers, resulting in shrinkage, resulting in shrinkage of the product size, unclear lines, etc., which seriously affect the appearance, feel, easy care and wearing performance. At present, the domestic wool anti-felting process generally adopts a relatively mature chlorination method and a two-step method of chlorinating a resin (IWS / CSIRO Chlorine Hercosett method). These two methods are based on chlorination treatment, which are easy to absorb chlorine and turn yellow, and cause great damage to the fiber strength. Not only the wool fiber is severely eroded by chemicals, but also there are a large amount of absorbable organic halogenated ...
