RU2599710C1 - Method of weaving decorative figures of fiberglass thread - Google Patents

Abstract

FIELD: manufacturing technology.

SUBSTANCE: proposed is a method of weaving decorative figures of a fiberglass thread. Method involves, first, taking three separate fiberglass threads, then weaving the three threads into a single thread-cable, after which the produced single thread is placed into a vacuum chamber, where during a short period of time it is impregnated with a composite resin. Then from those obtained woven cables the final product is formed by winding them on a prepared beforehand shape and drying at the temperature 70-90 °C to fix the shape, after which the prepared beforehand shape is extracted to obtain a decorative figure of the fiberglass thread.

EFFECT: uniform distribution of colouring agents, higher strength, reduced time expenses, improved aesthetic appearance.

Description

The proposed technical solution relates to light industry and can be used in the manufacture of festive wicker ornaments in the form of various types of figures, in particular Christmas-tree decorations - spherical, cubic, cylindrical or other shape.

The proposed technical solution is also aimed at creating high-quality material, namely fiberglass yarn, for the manufacture of decorative and applied products with high decorative effect.

Known artistic luminous decoration and method of its manufacture, see RU 83654 U1 from 10.06.2009. This decoration contains a hollow body of the figure, inside of which there are lighting. In this case, the lighting means is made in the form of a light-emitting layer located on the inner side of the body of the figure. The disadvantage of this product is the large weight, opacity of the decoration.

The closest technical solution is a decorative product and its production method described in the patent for utility model of Russia No. 37043 dated 04/10/2004. This decorative product includes a flexible longitudinal base into which a decorative material is painted in a predetermined manner, painted in uniform or heterogeneous colors and having the ability to simulate the shape, color and volume of objects or volumetric toys. In this case, the product is made in the form of a decorative ruff, containing a base made of flexible and preserving a given shape of the material and twisted helically by twisting around the base of the decorative material from fishing line. The disadvantage of this product is the inconsistency of the form (the finished product under the influence of external factors can change its shape).

The technical result of the proposed solution is a uniform distribution of dyes, increased strength, reduced time costs, improved aesthetic appearance.

The technical result is achieved due to the fact that the proposed method of weaving decorative figures from fiberglass yarn consists in first taking three separate fiberglass yarns, then three yarns are braided into a single yarn - a pigtail using a winder, after which the resulting single yarn is placed in a vacuum chamber , where for a short period of time it is impregnated with a composite resin, after the data of the obtained woven braids, the final product is formed by winding them on a previously obtained y and produce drying at a temperature of 70-90 ° C to secure form, after which the resulting pre-form is removed, thereby obtaining a decorative piece of fiberglass yarns.

In this case, the thickness of the threads can be selected in the range of 1.5-3 mm.

Prior to winding onto the previously obtained pigtail shape, an additional insulating layer of material may be applied to it. A stretch film, or polystyrene, or polycarbonate is used as the insulating layer of the material.

In addition, each thread before weaving can be preliminarily passed through a dye mixture and pigment paste, glitters are used as a dye, and any known transparent resin used for fiberglass, for example KDA, modified epoxy is used as a composite resin. In this case, all the threads are passed through a mixture of the same color or each of the threads is passed through a mixture of its color.

The preformed shape is a flat figure or a three-dimensional figure. Also, the preformed mold should preferably be hollow and be a product from either foam, or from plastic, or from glass, or from clay, or from another known easily destructible material. The previously obtained form is removed by its destruction to the smallest particles.

A decorative fiberglass thread figure is made according to any variant of the above method.

The proposed technical solution is illustrated in FIG. 1-3, where examples of manufactured decorative figures from fiberglass yarn are shown.

The proposed fiberglass thread is made as follows.

1. First, carry out the preparatory phase:

- prepare three bobbins with fiberglass thread (the threads can be of the same thickness, for example 2 mm, or different - 1.5 mm, 2 mm and 2.5 mm, and they can also be pre-painted in different colors),

- bobbins in the amount of 3 pieces are installed on a winding machine,

- using a winding machine, three threads are intertwined with each other, forming a single thread, which is wound on a spool of the required length.

2. Next, the resulting woven fiberglass thread is infused with a composite resin:

- a spool with interwoven thread is placed in a vacuum chamber,

- depending on the amount of thread wound on the spools, the required amount of composite resin is added to the vacuum chamber,

- in the vacuum chamber creates a vacuum (vacuum) of 10-1 MPa,

- in a short period of time, up to 2 minutes, the resin is impregnated with a fiberglass yarn.

This fiberglass thread impregnated with a composite resin is applied to the product circuit, and then left until the composite resin is fully polymerized.

The data obtained figures are shown in the drawings:

- so in FIG. 1 fiberglass thread was applied to the contour of the previously obtained ball shape and, accordingly, a decorative ball product was obtained,

- in FIG. 2 fiberglass thread was applied to the contour of the previously obtained star shape and, accordingly, a decorative star product was obtained,

- in FIG. 3 fiberglass thread was applied to the contour of the previously obtained cube shape and, accordingly, a decorative cube product was obtained.

These decorative figures can be used both without light, and with light. LEDs are used as a light source.

A specific embodiment of the proposed technical solution has been disclosed above, but it is obvious to any person skilled in the art that based on the disclosed data, it is possible to create variations of solutions using various geometric shapes of previously obtained shapes on which a fiberglass thread is applied. Thus, the scope of the claimed technical solution should not be limited to the specific option for its implementation, disclosed in the proposed claims.
