Embodiment 1

[0021] Cut the wool fabric into a circular sample with a diameter of 13cm, put it in a low-temperature plasma reaction chamber, and vacuumize it. When the pressure in the reaction chamber reaches 4Pa, start to introduce air to balance the vacuum degree in the reaction chamber at 26Pa, and then start discharging to conduct low-temperature plasma reaction. Plasma treatment, 30min discharge treatment with 200W power. The surface of the obtained fiber has a nano-scale concave-convex structure, and the diameter or width of the concave is 30-200nm.

Embodiment 2

[0023] Cut the wool fabric into a circular sample with a diameter of 13cm, put it into the low-temperature plasma reaction chamber, and vacuumize it. When the pressure in the reaction chamber reaches 7Pa, start to introduce oxygen to balance the vacuum degree in the reaction chamber at 160Pa, and then start discharging to carry out low-temperature plasma reaction. For plasma treatment, discharge treatment was performed for 60 minutes with 50W power. The surface of the obtained fiber has a nano-scale concave-convex structure, and the diameter or width of the concave is 30-200nm.

Embodiment 3

[0025] Cut the wool fabric into a circular sample with a diameter of 13 cm, put it into a low-temperature plasma reaction chamber, and evacuate it. When the pressure in the reaction chamber reaches 7Pa, start to feed helium / nitrogen (volume ratio is 6 / 4) to make the reaction chamber vacuum The temperature is balanced at 67Pa, and then the discharge is started, and low-temperature plasma treatment is performed, and the discharge treatment is performed for 1min with 300W power. The surface of the obtained fiber has a nano-scale concave-convex structure, and the diameter or width of the concave is 30-200nm.

Abstract

The present invention belongs to the field of functional fabric, and is especially no-fluff wool fabric of fiber with surface nano structure and its preparation. After wool fabric is set inside low temperature plasma processing cavity, the pressure inside the cavity is first pumped to not higher than 10 Pa and then regulated with introduced non-polymerizing gas to 10-170 Pa and the wool fabric is discharged for low temperature plasma processing at power of 10-300 w for 1-60 min, so as to form nano level embossed structure in the surface of wool fiber, to produce hydrophilic radical in the surface of wool fiber for fast escape of water and to obtain wool fiber with excellent fluff resisting performance. The wool fabric through the low temperature plasma processing may be further finished via softening, etc.

Description

technical field [0001] The invention belongs to the field of functional processing of textiles, in particular to an anti-pilling wool fabric with nanostructures on the fiber surface and a preparation method thereof. Background technique [0002] As a natural fiber, wool has always been a relatively high-grade textile raw material and is deeply loved by consumers because of its soft feel, firm texture, good curl elasticity and warmth retention, and natural and soft luster. However, when the fibers are entangled with each other due to static electricity, friction and other reasons, they form unsightly spherical clumps, which affect the appearance of clothing, which has always been a problem for consumers, manufacturers and researchers. [0003] Pilling of fabrics is a physical phenomenon. Due to the poor cohesion of the fibers, the fiber ends are easily exposed, forming hairballs through friction or accumulation of dirt. Generally, there are fiber hai...
