Abstract

PURPOSE:To obtain a synthetic resin molded article having soft luster, moisture permeability, absorptivity and enriched with nonelectrification, fungus resistance, durability or the like by mixing silk powder into a synthetic resin material at a specific percent by weight. CONSTITUTION:Silk powders are mixed into a synthetic resin material at 10-80% by weight, and then made into pellets. As the silk powders are mixed into the synthetic resin material, the granular configurations are of a state that spiral ones and free fine grains are being mixed microscopically, and the spiral silk powders interwine with one another like as net meshes and the free fine grains of the silk powders come into the skin film of the resin and dispersed in the form of being embraced thereinto, as a result, even the mixing rate of the silk powder is increased, the rate of frailty becomes less. Accordingly, molded articles molded with resin pellets in which silk powder is mixed with synthetic resin becomes of a type having excellent solidity, soft feelings and senses, calm color tone as well as excellent electrostatic resistance and moisture permeability, absorptivity or the like. And, the feelings and senses, color tone, electrostatic resistance, moisture permeability, absorptivity or the like can be changed freely by the mixing rate of the silk powder.

Description

[Detailed Description of the Invention] (Industrial Application Separation) The present invention is a synthetic resin molded product that has a soft gloss, moisture permeability, water absorption, and is rich in antistatic properties, antistatic properties, durability, etc. This relates to a pellet for molding.

(Prior art) In the case of a single molded product using only synthetic 1 and 1 lipid molecules, the luster lacks depth, and the 11 has noh mask, i.e., no water absorbency, so :jF i, :2 Shita static. Problems caused by 1L; (are occurring frequently.In an attempt to cover up this defect even a little, various materials are used as fillers for resin.In addition, with the recent trend toward higher quality products, Molded products with static electricity resistance, moisture permeability, water absorption, etc., soft luster, and calm color tone are now in demand.
As a solution to this problem, attempts have been made to mix natural leather powder into resin, and molding pellets for this purpose have been manufactured.

(Problems to be Solved by the Invention) However, conventional molding pellets have not yet been sufficient in terms of color tone, moisture permeability, water absorption, non-static properties, bacteriostatic properties, and durability.

(Means for Solving the Problems) The characteristic means of the present invention is to mix 10 to 80% of silk powder with a synthetic resin material and form it into a pellet, and its action is as follows. .

(Function) When silk powder is mixed with a synthetic resin material, the grains of silk powder have a shape that is microscopic! A:
Since AI-like particles and irregularly shaped fine particles are mixed, when these are dispersed in resin, the spiral silk powder becomes entangled like a net, and the irregularly shaped silk powder fine particles form a resin film. Because it is dispersed in a way that it penetrates into the silk powder and is hugged, even if the amount of silk powder mixed in is large, there is little chance of embrittlement. Therefore, molded products made from resin pellets made by mixing silk powder with synthetic resin are highly durable, have a soft feel, have a calm color tone, and have excellent static electricity resistance, moisture permeability, and water absorption. . In addition, the feel, color tone, static resistance, moisture permeability, water absorption, etc. can be changed freely by changing the proportion of silk powder mixed in. In other words, when the amount of the powder is increased, the characteristics of silk powder are more pronounced, and the product becomes more flexible, has a warmer feel, has a deeper color tone, and has better non-static properties, moisture permeability, and water absorption.

(Effects of the Invention) As described above, according to the present invention, compared to conventional products, the gloss is softer and the color tone is calmer, and the product has moisture permeability, water absorption, non-banding '4',
i. It is possible to supply pellets for synthetic resin molded products that have excellent water resistance, durability, and antibacterial properties.

Furthermore, by arbitrarily adjusting the mixing ratio of silk powder, it is highly flexible, warm to the touch, has excellent color 91Q and deep texture, and has non-static properties, moisture permeability, and water absorption.
It is possible to provide high-quality molded products with excellent properties such as water resistance, durability, and antibacterial properties.

(Example) Next, examples will be shown.

The washed silk mail was put into a pressure vessel with a heating jacket, and 3 kg/c- of steam was supplied to the inside of the vessel and the jacket to ILII H. First, the air in the vessel was replaced with steam, and then the vessel was sealed and heated for about 10 minutes. Heated for minutes. After the inside of the silk tissue was sufficiently swollen in this way, the outlet of the pressure vessel was opened all at once to cause swelling due to rapid pressure reduction. This was dried until the water content was around 10% and then ground using a media agitation type grinder to obtain silk powder with an average particle size of 15 μm. 25% of this silk powder was mixed with 75% of polyethylene resin containing tσ plasticizer and kneaded to make pellets. Use this pellet to inflate!
When put into a single machine and formed into a film, it had a moist and calm color tone, was moisture permeable, water absorbent, and non-static, and had excellent water resistance, durability, and antibacterial properties, and was used for various purposes as a laminate material. There are 7 high quality films that can be used for
I was attacked. In the present invention, conventionally used fillers or additives may be added in order to obtain a synthetic resin molded product with improved physical properties and functions. Further, in order to further characterize the feel of the surface of the molded product, a process such as sanding to thinly remove the resin layer on the surface may be performed as necessary.
