Description

Manufacturing method of mineral powder with high productivity {.}

According to the present invention, when the yarn is mixed with the chemical resin by using the mineral powder, the particles of the mineral powder are fine and uniform, and the foreign matter or other minerals are removed to remove the chips from the conventional mineral powder by mixing with the chemical resin. To solve the problems such as trimming, abrasion, and productivity that are a problem in the manufacturing process such as making process, spinning process, stretching process, and combustible product, it is possible to perform excellent production process without having excellent productivity, trimming, and wear of parts. To a process for the preparation of the composition.

The main cause of wear of the equipment, which was a problem in chemical fiber added with mineral powder, is that the crystalline form of the metal mineral (cleft) is made up of a variety of pyramidal, columnar, rhombohedral, hexahedral, octahedral, and dodecahedral forms. Due to the characteristic of irregularities on the surface of the yarn, the wear of the metal is not only worn out by friction, but also the spinning equipment is expensive. In addition, it was difficult to spin due to frequent trimming during spinning and could not produce normal yarn. Therefore, the surface of the fiber must be slippery in order for the synthetic fiber added with the mineral powder to be produced normally, so the crystal form is tabletop, plate-like or scale-like, and the functional phyllosilicate mineral (layered structure), pyrophyllite, The inventors of the present invention can produce a yarn of normal sand by forming a mineral powder such as kaolinite (serpentine) group, montmorillonite group, chlorite group, dolomite group, biotite group and adding to chemical resin. As filed with -2000-0017775, even the highly productive phyllosilicate minerals contain other minerals and foreign substances, so that these particles can be removed to uniformly form the particles of minerals and produce mineral powders with high productivity. Added to chemical resins for high productivity and good quality To be able to produce yarn in order are the object of the present invention.

Accordingly, in order to solve the above problems, the present invention provides a process for calcining at least one mineral selected from the group of natural minerals or artificial synthetic minerals beneficial and functional to the human body within the range of 500 ° C. to 1,200 ° C. according to minerals. The particle size of the mineral powder of the fine particles should be less than or equal to the yarn fineness during spinning, by grinding by a grinder over a mesh, followed by precision milling by second repetition, or by other grinding methods, and especially for yarn spinning of 3 denier or less. 1 micron or less is preferable.

Through this crushing process, the mineral powder and water are mixed in the wet process to attach the electromagnet to the equipment to remove the metal and foreign matters. In the next step, the large and small specific gravity particles are selected by the specific gravity method. After collecting and separating only the fine powder particles, the mineral powder of the fine particles obtained by passing through a filter film such as a special nonwoven fabric by adding a certain amount of water was excellent in functional effect, radioactivity or productivity, and yarn quality was also excellent.

Hereinafter, the present invention will be described in more detail with reference to Examples. The following examples are not intended to limit the invention to this, only to illustrate specific examples.

(Example 1)

In the process of precision grinding in the wet state by mixing the fine powder of mineral powder and water in a predetermined amount, the electromagnet is attached to the equipment to remove the metal and foreign matter, and then the large and small particles are separated by the specific gravity method to separate the small fine particles. After separating and collecting the bay, a certain amount of water was further added to pass through the filter film, thereby forming a fine powder of fine mineral powder having excellent radioactivity with uniform particles and foreign substances removed.

The present invention solves the problems caused by mixing the mineral powder with the chemical resin to produce the yarn and can remove the foreign matter and large particles of the mineral powder to produce a fiber that can produce a yarn with excellent productivity and excellent yarn quality It provides a composition containing a mineral powder that can be produced.
