JPH08149935A - Bed mat for livestock - Google Patents

Abstract

PURPOSE: To obtain a bed mat for livestock excellent in bulkiness, elasticity, air permeability and water permeability, and useful for horses, cattle etc., consisting of a double knitted fabric made up of a surface and back surface two-layer knitted fabric and threads connecting the two layers. CONSTITUTION: This bad mat for livestock consists of a double knitted fabric made, by using e.g. a double raschel knitting machine, from a surface and back surface two-layer knitted fabric such as a mesh knitted fabric or marquisette knitted fabric comprising e.g. polyester multifilament yarns 5-50 denier in single fiber fineness and 100-3000 denier in yarn fineness and connecting threads such as monofilament 200-2000 in single fiber fineness connecting the two layers. It is preferable that the total crossectional area of the connecting threads in 5cm<2> of the double knitted fabric is 0.1-2.0cm<2> .

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a floor mat for livestock.

[0002]

2. Description of the Related Art Horses, cows, sheep, pigs, boars, chickens, etc. are known as livestock, but when a horse is taken as an example, a conventional horse slab has a thickness of dried straw on the floor. It is spread out, and if it gets wet with manure or the like, it is dried outdoors and reused.However, especially in the cold season of winter, such as Hokkaido, the humidity is high, so the outdoors cannot be dried well. However, it is forced to be used in a damp state, which impairs the comfort inside the cabin.

[0003] Straw does not sufficiently remove dirt such as feces and urine even in a dry state, and further becomes insufficient in a damp state, so that the possibility of getting sick increases in combination with the use of damp straw. Therefore, if a large amount of straw cannot be prepared, it has been attempted to spread straw on synthetic fiber pile carpets, artificial grass, and felt-like materials to reduce the use of straw, but it is bulky, so straw is used. It is possible to reduce the use, but there are problems such as poor elasticity, difficult to dry (poor breathability), poor water permeability, and difficult to remove dirt by washing with water. It has not been put to practical use because there is a problem that horses will cut off the pile.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a livestock floor mat which meets such requirements and is excellent in bulkiness, elasticity, breathability and water permeability.

[0005]

That is, the present invention comprises a double knitted fabric composed of two layers of front and back knitted fabric and a connecting yarn for connecting the double knitted fabric. Located on the floor mat. The double knitted fabric of the present invention is a knitted fabric formed by a knitting machine having a double-row needle bed, and can be knitted by, for example, a double Raschel machine, a double circular knitting machine, etc. The material of the yarn used for is not particularly limited, and may be synthetic fibers such as polyester, polyamide, polyacrylonitrile and the like, regenerated fibers, wool, natural fibers such as cotton, but synthetic fibers rich in quick-drying are preferred, Polyester is particularly suitable.

The front and back knitted fabrics may be knitted fabrics having a plurality of openings such as a mesh knitted fabric and a marghizette knitted fabric to further improve air permeability and water permeability. The yarns constituting the front and back knitted fabrics are preferably multifilaments having a single yarn denier of about 5 to 50 denier and a total denier of about 100 to 3000 denier. Regarding the connecting yarn, a monofilament or multifilament having a single yarn denier of 50 to 2000 denier, preferably 200 to 2000 denier is preferable in order to obtain appropriate elasticity and rebound.
When the number of connecting threads within 5 square centimeters is N (pieces / 5 cm ² ), the denier of the connecting threads is D (g / 9 × 10 ⁵ cm), and the specific gravity of the connecting threads is ρ (g / cm ³ ). , The total cross-sectional area of the connecting yarn in the double knitted fabric 5 square centimeters (ND / 9 × 1
0 ⁵ · ρ) is 0.05 to 5.0 cm ² , preferably 0.
When it is from 1 to 2.0 cm ^2, it is suitable as a floor mat for livestock because it is excellent in bulkiness, elasticity, breathability, and water permeability, and is excellent in its balance. 0.05 cm
^When it is less than ² , the elasticity is high, and when it is more than 5.0 cm ² , breathability,
The water permeability tends to decrease.

The connecting yarn may have loop-shaped stitches formed in the front and back knitted fabrics, or may have a structure in which the front and back knitted fabrics are hooked in a tuck structure. The connecting yarns may be arranged so as to be inclined or crossed in an X shape. The thickness and basis weight of the double knitted fabric may be appropriately selected as desired. For example, the thickness is 10 to 4
0 mm, preferably 15 to 30 mm, with a basis weight of 5
About 00 g / m ^{2 to} 2.5 kg / m ² , preferably 1.
About 0 to 2.0 kg / m ² is preferable. Further, the double knitted fabric may be cut into a desired size if necessary, or the knitted fabric piece after cutting may be used by sewing or thermoforming into a desired shape.

EXAMPLES The present invention will be specifically described below with reference to examples, but the present invention is not limited to the examples. <Practical evaluation> A double knitted fabric is laid on the floor of a shack, and straw is laid on it for practical use for 3 months. It is bulky, elastic, easy to dry, and easy to remove stains by washing with water. Was evaluated by an expert's sensory evaluation.

[0009]

[Example 1] A double Raschel machine equipped with 6 reeds was used, and two reeds located in the middle were used as connecting yarns for 1000
The polyester monofilament yarn of d is supplied, and the polyester multifilament yarn of 500d / 20f is supplied as yarns for the front and back knitting fabrics from two reeds located on the front side and the back side of the knitting machine, respectively, and the thickness is 20 mm and the basis weight is 0.8 kg /
m ² , mesh size 5 mm, breathability 500 cc / cm
^A double knitted fabric of ² / sec was obtained. The total cross-sectional area of the connecting yarn per 5 cm 2 of this double knitted fabric was 0.2 cm ² .

As a result of practical evaluation of the obtained double knitted fabric, it was found that the bulkiness and elasticity were equivalent to those of the conventional case of only straw, but it was easy to dry, and the stain was removed by washing with water. Ease of use was remarkably excellent.

[0011]

Comparative Example 1 Nylon 66 having a pile length of 13 mm and a basis weight of 750 g / m ² instead of the double knitted fabric in Example 1.
Evaluation was made in the same manner as in Example 1 except that a cut pile carpet made of BCF was used. Comparative Example 1 was comparable in bulkiness to the conventional straw alone, but was inferior in elasticity, easiness of drying and easiness of stain removal by washing with water.

[0012]

INDUSTRIAL APPLICABILITY The present invention provides bulkiness, elasticity and breathability,
It is possible to provide a floor mat for livestock having excellent water permeability.
