Problems solved by technology

This kind of process of making artificial flowers with woven fabric as raw material usually has the following problems: the woven fabric is made of weaving threads or fibers interwoven horizontally and vertically, and when the woven fabric is cut into petal-shaped pieces, the edge is prone to " Burr off" problem
[0005]Secondly, the fabric is cut directly by hot cutting, that is, when the petal-shaped material is cut, the cutting ports of the fibers are fused to prevent it from spreading However, this method is usually suitable for single-layer fabric cutting. When multi-layer fabrics are stacked and cut, it is easy to cause adhesion between fabric layers, which affects processing efficiency and cutting effect, and limits the improvement of artificial flower production efficiency.
[0006]Third, the woven fabric is coated to improve the stiffness of the woven fabric while making the weaving threads or fibers of the woven fabric adhered by the coating. The weaving thread or fiber at the edge is not easy to come off, but this method inevitably has the problem of VOC pollution

preparation example 1-4

[0064] Preparation examples 1-4 all relate to a kind of non-woven fabric preparation process, and the process steps are as follows:

[0065] Step 1. Dry the spinning particles at 160-175°C, and then heat to 250-270°C to melt the spinning particles to form a spinning material; the spinning particles can be PET particles, PP particles, or PET particles and PBT particles mixture;

[0066] Step 2, the spinning material is sprayed through the spinneret and spun into fiber filaments with a thickness of 1-2D;

[0067] Step 3. After the fiber filaments are flattened into a web, use at least one embossing roller to cooperate with the pressure roller to carry out hot pressing and shaping to obtain a grammage of 20-120g / m 2 The surface of the embossing roller is evenly distributed with embossed bumps, the embossed bumps are in the shape of straight lines or curved strips, and the cross-section is rectangular or trapezoidal. When choosing multiple embossing rollers and backing rollers f...

Embodiment 1

[0087] A kind of non-woven fabric imitation flower production process, with the non-woven fabric that preparation example 1 makes as petal production raw material, refer to Figure 6 , the specific process steps are as follows:

[0088] (1) Cutting process

[0089] The non-woven fabric is cut into petal shapes to obtain cutting pieces. In order to facilitate the subsequent clamping and fixing device by means of the blank, a through hole is formed in the central part of the cut blank synchronously during cutting. In order to improve the cutting effect, 2 to 20 pieces of non-woven fabrics can be laminated and then cut synchronously during cutting, so that multiple petal-shaped cutting pieces can be obtained at one time. In this example, when cutting, 10 sheets of nonwoven fabrics were laminated at a time.

[0090] (2) Dyeing process

[0091] refer to Figure 7 and Figure 8 , the dyeing process needs to be completed by clamping and fixing the tablet. The sheet clamping an...

Embodiment 2

[0105] A non-woven fabric artificial flower production process, using the non-woven fabric prepared in Preparation Example 2 as the raw material for making petals, the difference from Example 1 is that the process parameters of each step are different, see Table 4 for details.

Abstract

The invention relates to the technical field of artificial flowers, in particular to a manufacturing process of a non-woven fabric artificial flower and the artificial flower, and aims to solve the problem of burr separation in the artificial flower manufacturing process in a simpler mode. According to the manufacturing process of the non-woven fabric artificial flower, a non-woven fabric serves as a raw material for manufacturing petals. A manufacturing process of the non-woven fabric comprises the steps that 1, spinning particles are dried, heated and melted, so that a spinning material is formed; 2, the spinning material is sprayed out through a spinning nozzle to be spun into fiber filaments; and 3, after the fiber filaments are flatly laid to form a web, at least one embossing roller and a pressure-bearing roller are matched for hot-pressing and setting, so that the non-woven fabric is obtained, wherein embossing protruding blocks are evenly distributed on the surface of each embossing roller. The artificial flower manufactured by adopting the process is not liable to have the problem of burr separation, the petal edges do not need to be subjected to melting or fusing treatment, the petal raw material does not need to be subjected to coating treatment, and the artificial flower has the advantages of simple process and low VOC. The invention also correspondingly discloses the artificial flower prepared by the process.

Description

technical field [0001] The application relates to the field of artificial flowers, in particular to a non-woven artificial flower manufacturing process and artificial flowers. Background technique [0002] Artificial flowers refer to artificial flowers made of stretch silk, crepe paper, polyester, plastic, crystal and other materials, which are generally called artificial flowers in the industry. Artificial flowers generally consist of fabric petals as the main body, and the petal-mimicking fabric pieces are molded into lifelike shapes and colored and / or printed to provide a visually realistic appearance. Cloth is widely used in the production of non-woven fabrics due to its advantages of being easy to manufacture. Usually, in order to keep the petals in a firm and three-dimensional shape for a long time, it is more common to make artificial flower petals with woven fabrics, especially polyester woven fabrics. This kind of process of making artificial flowers with woven fab...
