Problems solved by technology
These three discharge plasma chemical fiber fabric surface modification technologies have their own unsolvable problems, which affect their development and application.
Low-pressure glow discharge plasma can provide large-area, uniform plasma, and achieve uniform surface modification of chemical fiber fabrics without damage, but it must be operated under low pressure. Due to the need for vacuuming, the equipment investment is large and the operation is complicated. It is difficult to realize industrialized production; and 85% of the electric energy used is used to maintain dynamic vacuum, which consumes a lot of energy and costs high, so the surface modification technology of low-pressure glow discharge plasma chemical fiber fabrics is not suitable for wide application in industrialization
Although atmospheric pressure corona discharge and silent discharge plasma work under normal pressure, there are a large number of filament discharges with high energy density in the discharge plasma, which will cause damage to the fabric and are not suitable for surface modification of chemical fiber fabrics.

Embodiment Construction
[0047] A system for modifying the surface of silk and chemical fiber fabrics with atmospheric pressure glow discharge plasma under normal pressure. Gas system, gas heating cycle system, gas composition and plasma activity analysis system and computer data acquisition and control system.
[0048] The partition fixed on the front flange of the modification device separates the modification device into a sampling room, a modification room and a finished product room. The chambers are connected; the center of the modification chamber has two pairs of rectangular stainless steel discharge electrodes on the same level, placed horizontally, cooled by water, and has a mirror-clean surface. A curved surface with a radius of curvature of 20mm is made around the electrode, and a thin aluminum oxide or quartz glass dielectric sheet with a thickness of 0.1-2mm is fixed on the opposite inner surface of the two electrodes. The normal pressure glow discharge between the electrodes provides th...

Description
technical field [0001] The invention belongs to the technical fields of chemical fiber modification, glow discharge and plasma. It involves the discharge plasma surface modification system and technology of chemical fiber fabrics, especially a large-area, uniform and non-damaging atmospheric pressure glow discharge plasma APGDP suitable for experimental research and application of Silpron and chemical fiber fabrics Surface modification systems and technologies. Background technique [0002] Because the raw material polypropylene of fine denier and superfine denier polypropylene fibers is rich in polypropylene, low in price, light in weight and warm in weight, stable in performance, good in wicking, and able to wick away moisture in one way, it has become a popular choice for high-end underwear and sportswear. The preferred fabric for shirts, known as "body clothing air conditioner", is a nearly perfect textile fiber, which has great competitiveness and broad development pro...
