The invention discloses a method for preparing nylon yarns. The method comprises the following steps: mixing, blending, spinning, cooling and then winding an organic copper complex, color masterbatches and PA6 slices into bobbins, wherein the organic copper complex is obtained after a coordinated ionic liquid reacts with copper powder oxidized by an oxidant, and the color masterbatches are obtained through blending granulation of the PA6 slices, germanium powder slurry and modified negative ion far-infrared powder. The method has the beneficial effect that the nylon yarns obtained by the preparation method are healthier and safer to the human body.
摘要:
The present invention relates to a method for hydrophobization of a fabric surface comprising providing a stream of a substantially anhydrous gas, passing said gas over or through a substantially anhydrous liquid of an alkylsilane, preferably a fluorinated alkylsilane to provide an alkylsilane, preferably a fluorinated alkylsilane vapor and bringing said vapor in contact with the fabric surface, thereby allowing the optionally fluorinated alkylsilane to bind covalently to the fabric surfaced. The present invention further relates to a fabric comprising a superhydrophobic surface finish prepared by a method of the invention and to a device for carrying out the method of the invention.

A method for manufacturing an electret filter element includes preparing fibers and producing, by a spray device, a spray mist of fluid droplets which include an electrical charge formed by an electric field between detaching fluid droplets and a counter-electrode. The fibers are passed through the spray mist so as to wet the fibers with the fluid droplets. The fibers are laid down to form a fibrous layer.
摘要:
A method of making an electret article, from a polymeric article that has a zeta potential of greater than or less than −7.5 millivolts. The article is charged by contacting it with an aqueous liquid that has a pH and conductivity as follows: (i) if the article has a zeta potential of −7.5 mV or less, then the contacting liquid has pH greater than 7 and a conductivity of 5 to 9,000 microSiemens per centimeter; and (ii) if the article has a zeta potential of greater than −7.5 mV, then the contacting liquid has a pH of 7 or less and a conductivity of 5 to 5,500 microSiemens per centimeter. An electret article made in this manner can provide improved electret performance, particularly in electret filtration articles.
摘要:
The present invention provides regenerated collagen fibers which have light color and excellent touch in wet conditions and which can be formed into desirable shape with the shape being maintained properly. The present invention also provides regenerated collagen fibers whose foul odor generated in thermal treatment can be inhibited. The present invention relates to regenerated collagen fibers obtained by treating collagen with a monofunctional epoxy compound and an aluminum salt. The present invention also relates to a process for preparing regenerated collagen fibers which comprises treating collagen with a monofunctional epoxy compound, and then treating the same in such a way that 2 to 40% by weight of an aluminum salt converted to an aluminum oxide (Al2O3) basis is contained to said collagen.

摘要:
A manufacturing method of an electret processed product, comprising the steps of allowing a section nozzle (22) to come into contact with a nonconductive fiber sheet (S) so as to cross in the lateral direction of the sheet while running the sheet, allowing the surface of the sheet on the opposite side of the contact portion to come into contact with or to immerse into a water surface, sucking water from the suction nozzle (22) so that the water can be passed through the sheet in the thickness direction of the sheet to penetrate the water into the nonconductive fiber sheet (S), and drying the nonconductive fiber sheet (S), whereby a high quality and high performance electret processed product can be manufactured at a low cost.
摘要:
A process for diffusing and subliming water-soluble and water-insoluble materials into never-dried, shrinkable aromatic polyamide fibers, using steam heated at certain controlled temperatures, within a specially designed treatment chamber and a process and apparatus for treating a tow of shrinkable material.
摘要:
A method of treating fabric articles to impart a durable press thereto comprises subjecting the articles to steam in a rising temperature due to the steam, subjecting the articles to formaldehyde and sulphur-dioxide vapors and steam at a higher temperature, allowing the temperature to fall, circulating air from the outside to remove steam and free chemicals and circulating dry heated air in a closed system to raise the temperature of the articles to around 250*F. Finally, cool air and water spray are employed to return the articles to room temperature.
