JP2001146630A - Fine powder produced by crushing ultrafine synthetic fiber - Google Patents

Abstract

PROBLEM TO BE SOLVED: To diversify the sense of value, taking advantage of the fact that the surface gloss is dependent on the surface smoothness and refractive index, by varying the surface state with a surface processing agent to an appearance having absolutely different texture and giving a new value and thereby changing two-dimensional metallic flat gloss inherent to a smooth surface having high refractive index to cause the reflection of light on the surface to a velvet-tone deep refreshing gloss such as a robe-petal or peach-skin surface varying the appearance by the viewing angle. SOLUTION: Light is irregularly reflected on the surface by the use of fine powder produced by pulverizing ultrafine synthetic fiber or its fragment. The surface having smooth texture, high refractive index and metallic gloss can be converted into a surface having characteristic fuzzy velvet gloss of ultrafine fiber powder without changing the color tone of the surface.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001] The present invention relates to an optical characteristic of a fine powder obtained by finely cutting ultrafine synthetic fibers (when the fibers become finer, the specular gloss is lost and a velvety gloss appears.) ) And physical characteristics (the fibers are thin and short, so they are soft and difficult to entangle and do not clump together), while having a smooth surface, but with a velvet-like appearance typified by rose petals and peach skin It relates to fine powder that creates gloss. .

[Prior Art] Conventionally used ultrafine fiber powder has a diameter of 10 μm or more and a length of 300 μm or more, so that physical properties as a fiber appear strongly. There were many restrictions, and there was no use as a material for adjusting the surface gloss.

[0003] The object of the present invention is to develop a glossy surface having a smooth surface and exhibiting a deep velvet-like luster as seen in rose petals or peach skin. I do. .

[Means for Solving the Problems] In order to create a smooth and velvet-like surface, a fine powder obtained by finely cutting ultra-fine fibers is utilized, and complicated light irregular reflection of the fiber by the fine fiber powder is performed on the surface. Wake up.

[0005] Synthetic fibers are made of materials that are safe and stable against ordinary acids, alkalis, various organic solvents, etc.
Polyester fiber, acrylic fiber, polyamide fiber, or a mixture of these fibers, ultra-fine size powder (thickness of 3 microns or less), considering inhalation toxicity, light stability, hydrophilicity, lipophilicity, etc. Apply

DESCRIPTION OF THE PREFERRED EMBODIMENTS Coarsely cut ultra-fine fibers are embrittled by low-temperature treatment (using liquid nitrogen, dry ice, etc.), and a volume pulverizer (Jetmizer,
A fine powder (5 to 100 microns in length) which has been pulverized by a pulverizer or the like and then sized by a classifier (wind chill, water chill).

By coating the surface with fine powder of ultra-fine fibers, the surface gloss changes from a metallic one to a three-dimensional and deep gloss due to irregular reflection of light.

In order to fix the fine powder of ultrafine fibers on the surface, a surface coating agent (semi-solid to liquid) is used as a binder. Specifically, when applying and mixing the coating agent and the fine powder during surface processing, when applying using the surface coating agent with the fine powder added to the matrix of the coating agent, or when applying the fine powder to the surface wet with the coating agent. May be applied directly.

[Example 1] Fine powder is dispersed in a solvent / volatile type coating agent, and is uniformly applied to the surface using a tool such as a brush or a spray gun. (Paints and glazes, cosmetics,
Upholstery, processed paper, etc.)

[Embodiment 2] A fine powder is dispersed in an oily, aqueous, emulsion type coating agent and uniformly applied to the surface using a coating tool. (Paints, cosmetics, eel, processed paper, etc.)

Example 3 A fine powder is directly applied to a surface moistened with a coating agent using a tool. (Painted surface, makeup skin, painting, upholstery, etc.)

[Effect of the Invention] The fine powder of ultra-fine fibers is randomly oriented on the surface of the object and causes irregular reflection of light, which is different from the conventional surface gloss and has a velvet-like tone which varies with the angle of light. A new value is created by expressing the luster of the deep texture, and the inside of the coating is used as a material for strengthening the strength of the coating by joining together the polymer forming the coating and serving as a wedge. Is also effective. The fields of application are diverse, such as paints, cosmetics, papers, and paintings.
