Problems solved by technology

[0005] However, in this floor mat, the needle-punched nonwoven fabric constituting the back surface entangles the constituent fibers of the fiber web by weaving to make the fiber web dense and protrude a part of the constituent fibers, so the tensile strength tends to decrease. Defects
Therefore, in order to ensure sufficient tensile strength, it is necessary to increase the weight per unit area (weight per unit area of ​​Japanese fabrics, 4.356 grams per square meter), making it difficult to manufacture light and thin products
[0006] In addition, in this floor mat, on the one hand, the durability and anti-slip properties are improved by using thick fibers, and on the other hand, a non-woven fabric with excellent texture is formed by using fine fibers in combination. The knitting needles make the fibers protrude and make the fiber web dense, so it is difficult to satisfy the two properties of durability, slip resistance and excellent texture at the same time

Embodiment 1

[0047] Use polyester fiber (coarse fiber) with a fineness of 90dtex and a fiber length of 76mm and a polyester fiber (fine fiber) with a fineness of 6.6dtex and a fiber length of 51mm, and mix them at a ratio of 50%:50%. form a fiber web.

[0048] Next, use knitting needles with a barb depth (0.12mm) corresponding to the fineness of the fine fibers 6.6dtex (100 / cm from above) 2 , 60 pieces / cm from below 2 ) to implement complexation treatment.

[0049] Then, through the above-mentioned complexation treatment, such as figure 2 As shown, a high-density fiber layer mainly composed of thin fibers is formed at the center, and a low-density fiber layer mainly composed of thick fibers is formed on the surface of the high-density fiber layer.

[0050] Afterwards, the low-density fiber layer is heat-treated. From above the low-density fiber layer, the fibers constituting the low-density fiber layer are singed with a gas heater to perform heat treatment. By this heat treatment, th...

Embodiment 2

[0052] A base material was produced in the same manner as in Example 1, except that the blending ratio of the thick fiber and the thin fiber was set at a ratio of 20% of the thick fiber and 80% of the thin fiber.

Embodiment 3

[0054] Use a polyester fiber (thick fiber) with a fineness of 44 dtex and a fiber length of 76 mm and a polyester fiber (fine fiber) with a fineness of 6.6 dtex and a fiber length of 51 mm, which are set as thick fibers A base material was produced in the same manner as in Example 1 except that the ratio of 20% and 80% of thin fibers was used. The diameter of the resin block at the tip of the fiber fused by the heat treatment is 0.10 to 0.24 mm.

Abstract

The invention provides a preparation method for basis material for ground cushion with sufficient tensile strength, featheriness, sufficient durability and sliding resistance and basis material for ground cushion. The preparation method comprises: forming fiber web constituted of raw fiber (12) and fine fiber (11); complexing the fiber web using knitting needle with barb depth corresponding with the fine degree of the fine fiber (11); thus forming high density fibrous layer (13) mainly of fine fiber (11) in the center and forming low density fibrous layer (14) mainly of raw fiber on the surface of the high density fibrous layer (13); then heating the low density fibrous layer (14) to melt the fiber for forming the low density fibrous layer (14) to form resin block (15).

Description

technical field [0001] This invention relates to the manufacturing method of the base material for floor mats, and the base material for floor mats. Specifically, it can be applied to mats placed on the ground of vehicles such as automobiles, trains, and airplanes, mats placed on the ground in buildings or corridors, entrances and exits of rooms or in front of elevator doors, or front doors of houses, etc. The manufacturing method of the base material for floor mats of a floor mat, and the base material for floor mats. Background technique [0002] Conventionally, for example, floor mats are placed on the floor of the cabin of an automobile to prevent soil or mud adhering to shoes and the like from soiling the floor. A needle-punched nonwoven is bonded to the back of the floor mat, which has a surface roughened by local melting of the fibers, preventing the mat from slipping. However, slippage cannot be sufficiently prevented on the surface roughened by local melting of fi...
