Problems solved by technology

However, these darkening finishes need to be carried out after dyeing, so the process is complicated and the cost rises. More importantly, the darkening effect is limited, and super black fabrics cannot be obtained.

Embodiment 1

[0029] Put the wool fabric into the low-temperature plasma reaction chamber, vacuumize, and when the pressure in the reaction chamber reaches 4Pa, start to introduce air to balance the vacuum degree in the reaction chamber at 26Pa, then start discharging, and perform low-temperature plasma treatment for 30 minutes with 200W power The discharge treatment of the nanometer-scale concave-convex structure is formed on the surface of the fiber, and the diameter or width of the concave part is 30-200nm.

[0030] The above-mentioned wool fabric having a nano-scale concave-convex structure on the surface was dyed according to the following conditions.

Embodiment 2

[0041] Put the wool fabric into the low-temperature plasma reaction chamber, vacuumize it, and when the pressure in the reaction chamber reaches 7Pa, start to introduce oxygen to balance the vacuum degree in the reaction chamber at 160Pa, then start discharging, and perform low-temperature plasma treatment for 60 minutes with 50W power discharge treatment. Except that Acid Media Black 2B was used instead of Acid Media Black T, other dyeing conditions were the same as in Example 1. The ultra-black wool fabric with nano-scale concavo-convex structure on the fiber surface is obtained, and the width of the concavity is 30-200nm.

Embodiment 3

[0043] Put the woolen fabric into the low-temperature plasma reaction chamber, vacuumize it, and when the pressure in the reaction chamber reaches 7Pa, start to feed helium / nitrogen (volume ratio is 6 / 4) to balance the vacuum degree in the reaction chamber at 67Pa, then start discharging, and carry out For low-temperature plasma treatment, discharge treatment was performed for 1 minute with 300W power. The other dyeing conditions were the same as in Example 1 except that acid media black PV was used instead of acid media black T. The ultra-black wool fabric with nano-scale concavo-convex structure on the fiber surface is obtained, and the width of the concavity is 30-200nm.

Abstract

The invention relates to the field of fabric fanctional disposing, and specially relates to the field of micromillimeter structured super black wool fabric and its preparing method. Laying wool fabric into low-temperature plasma treatment box, and reduce the pressure to 10Pa or lower, the pressure of pneumatic control box passing over non-conglomerate gas is 10-170Pa;then discharge and low-temperature plasma proccess. The power is 10-300W, and processing time is 1-60 min. Forming millimicron level concavo convex on the surface and active group, then normal dying.

Description

technical field [0001] The invention belongs to the field of functional processing of textiles, and in particular relates to an ultra-black wool fabric with a nanostructure on the surface and a preparation method thereof. Background technique [0002] As a natural fiber, wool has always been a relatively high-end 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. Black wool fabrics are often used in formal wear fabrics, but as consumers have higher and higher requirements for high-end formal wear fabrics, many countries and regions have developed ultra-black fabrics one after another. [0003] South Korea's primary industry company has recently developed a super black fabric, according to the company's report, its color rendering is 50% higher than that of ordinary wool fabric, and the K / S value exceeds 32. The K / S value of ordinary bl...
