The invention discloses a method for reducing the sulfur content of a nickel cobalt aluminum precursor. Sulfate radicals adsorbed at the surface of the nickel cobalt aluminum precursor can be removed by traditional alkali liquid such as sodium hydroxide and lithium hydrate, but the removal effect on the sulfate radicals in the nickel cobalt aluminum precursor crystalline structure is poor; the requirement of a power battery positive electrode material on the impurity sulfur content is different to meet. The method is characterized in that a nickel cobalt aluminum mixed metal solution, sodium hydroxide and ammonium hydroxide are added into a reaction kettle at the same time; the nickel cobalt aluminum precursor is obtained through controlling the reaction conditions; after the mother liquid removal, the nickel cobalt aluminum precursor is transferred into a washing kettle to be subjected to sizing washing and water washing; then, drying and sieving are performed to obtain the nickel cobalt aluminum precursor with the sulfur content being smaller than or equal to 1000ppm. The method has the advantages that the washing solution is low in cost; the washing process is simple; the operability is high; the efficiency is high; no destroy effect is generated on the microtopography of the nickel cobalt aluminum precursor; the method belongs to a process applicable to industrial production; practical values are realized.

The invention relates to a weaving method for seamless non-snagging warp-knitted panty stockings. The seamless non-snagging warp-knitted panty stockings comprise a panty waist, panty bodies, a stocking crotch, stocking legs, front-rear pieces joints, stocking points, stocking heads and partitions and are formed by weaving elastic yarn materials; the stocking waist, the stocking bodies, the stocking legs, the stocking points and the stocking heads are formed in a way of a circular weaving that the stocking heads are woven to the stocking waist and the stocking waist is woven to the stocking heads by using a unique weaving rule of the warp weaving; front and rear pieces at the stocking crotch and the stocking heads are sewn and organized to form two longitudinal lines and eight columns; the partitions are formed by weaving mutually-clasped chains of the front piece and the rear piece; and the partitions are sheared off after the panty stocking textile is unloaded from the machine and then a pair of complete panty stockings is formed. The panty stockings are formed by weaving on a double needle bar by using a unique weaving rule of the warp weaving. The weaving method is finished by one work procedure without additional sewing; joints which easily scratch or rub the skin are avoided; due to the application of elastic yarns, the panty stockings have ideal fitness; and due to the use of a mesh structure, the panty stockings have favorable permeability.
