Description

Detailed Description of the Invention A. Field of Industrial Application This invention uses wool as the main material, arranges natural fibers and thermoplastic synthetic fibers with a relatively low melting point, and heats and fuses the thermoplastic synthetic fibers. Concerning futon cotton and manufacturing method.

BACKGROUND OF THE INVENTION Conventionally, it has been known to use wool as futon cotton for bedding. By the way, when wool is used directly as futon cotton, the tips of the wool may protrude outward from the weave of the side fabric during use. ) using fabric. However, wrapping a wool comforter in a side fabric with a high weave density and a fine weave will impede the breathability of the fabric.
The disadvantage is that wool's natural crimps, scales, curls, etc. make it difficult to exhibit its heat retention, elasticity, and flexibility.

In addition, wool has a moisturizing ability, so it does not feel hot or cold, and its elasticity changes depending on the humidity, but if it is wrapped in a non-breathable fabric like the one mentioned above, it can be used as bedding. This makes it difficult for the moisture to dissipate to the outside, and as time passes, the original elasticity is lost and it aggregates into a felt-like form, which may reduce the bulk and suppleness of the bedding. Synthetic fibers are also used as raw cotton for futons, but in most cases, thermoplastic synthetic fibers with a low melting point are blended and the resulting cotton layer is used for filling. Since this material is made only of synthetic fibers, the surface is smooth, and there are no crimps or scales, so there are no serrations.
The natural qualities of wool and natural fibers: warmth, softness,
I'm disappointed that it doesn't feel as good on the skin.

C0 Problems to be Solved by the Invention Here, the present invention aims to make it possible to fully exhibit the bulkiness and suppleness of wool bedding cotton, and to improve the entanglement, curling and bending properties of the scale-like tissue. , adapt it to bedding by utilizing its heat retention, elasticity, etc., and eliminate the disadvantages of the synthetic fibers by satisfying the characteristics that are not comparable to natural fibers, and impairing the inherent characteristics of wool. Our aim is to provide bedding such as futons and cushions that can be used effectively without having to use them.

2. Means for solving the problem In order to achieve this objective, the present invention implements the following means. That is, the futon cotton according to the present invention is a blend of wool as the main material (weight: 10 or more), natural fibers as secondary materials, and thermoplastic synthetic fibers with a relatively low melting point (below 180°C). A plurality of sheets of the carded and thin-layered web are stacked in a molding machine to form a mat-like fibrous body of °C raw material, and the fibrous body is passed through a dryer and heated from low to high temperatures to melt the synthetic fibers. The bath melting part partially fuses and binds the wool and the fibers, thereby preventing the fibers from attaching to each other and detaching from each other, thereby providing a comforter with a good feel. 1. What is a thermoplastic synthetic fiber with a relatively low melting point? 1tvffi Holie f V system melting point (m

p) 160-170°C force ζ.

E) The futon yarn provided by this invention is mainly made of wool, mixed with cotton and cotton, each fiber is tangled and the synthetic fibers are partially fused together. The appropriate properties and effects for bedding are expressed by a combination of these fibers. When the low*AA thermoplastic synthetic fiber is in a molten state, the wool and the 10 mixed fibers are partially fused and restrained, resulting in a fluffy mat shape, and when the wool glue is Due to its elasticity and scale, it becomes a gas-containing fiber, and cotton and cotton provide softness and heat retention, while its serrations provide a product with firmness and firmness.

Example- Next, embodiments of the invention will be described with reference to the drawings.

First Example: One type of thermoplastic synthetic fiber In Fig. 1, wool 2 is made by scouring and bleaching raw wool to remove impurities, pigments, dust, yoke, etc., cotton 3, cotton cotton 4, and wool with a relatively low melting point. Among thermoplastic synthetic fibers, polypropylene (P, P) fibers 6 were used (11) and carded into a combed card with a mixture of 70% wool, 10% cotton, 5% cotton, and 15% by weight. , Webb l. A plurality of sheets of this web are stacked in a molding machine to form a raw mat-like fibrous body, and the fibrous body is heated from 160°C to 180°C sequentially in a hot air dryer to melt the P, P, and fibers. The fused portion is partially fused to the wool 2 and other mixed fibers, and the fused portion 7 becomes a lump and is fixed. At this temperature, the wool does not change much, but the scale on the surface softens slightly, causing p, p.

The fibers are fused and the fibers are prevented from attaching and detaching from each other, so there is no fear that the fixing section 10 will separate.

Second Embodiment Two types of thermoplastic synthetic fibers In FIG. 2, the same reference numerals as in FIG. 1 indicate the same parts. wool 2, cotton 3, cotton cotton 4, and polyethylene (P, 6',) based fibers 5 among thermoplastic synthetic fibers with relatively low melting points;
Adopting polypropylene (p, p,) type fiber 6, wool ω weight 0 cotton 5 cotton 5 p, 6. 15 p, 1; 1. The blended cotton mixed in the ratio of 15% is charged into a carding machine and carded in the same manner as in Example 1 to obtain Wetspro) 8. A plurality of sheets of this web are piled up in a forming machine to form a raw material strip-like fiber body, and the fiber body is placed in a hot air dryer at a drying temperature of 150 to 160
℃ for 1 minute to melt the P, E, fibers and partially fuse them to each fiber, then increase the temperature to 170-200℃.
Heat for 1 to 15 minutes to melt the P, P, fibers. P, P, fibers melt from 160℃,
The fused portion is partially fused to the wool 2 and other mixed fibers, and the fused portion 7 of the side fibers of p, e, , p, p is fixed as a slight lump. The wool does not change much, but the scale part on the surface softens a little, so P is applied to this part.
, e, , p, p.

The side fibers are fixed and the fibers can be prevented from attaching to each other and detaching from each other, and the fixing portion does not separate.

In this way, wool, cotton, and floss are each partially bonded into a web 8 without changing their natural properties, and a plurality of sheets of this web 8 are laminated to form a futon cotton 9 of an appropriate thickness. .

Then, as shown in FIG. 3, the futon cotton 9 is wrapped in a side fabric 11 with a coarse weave and good air permeability and used as it is, or it is quilted to provide bedding. It is something.

(6) Effects of the invention Almost all of one's life time is spent resting. A cobblestone rest can be obtained by having a good night's sleep. The futon cotton of the present invention is constructed to meet the above-mentioned purpose as much as possible as bedding and clothing cotton such as futons, blankets, and cushions. A futon cotton suitable for practical use was provided by entangling fibers or distributing cellulose fiber cotton or natural fiber floss and bundling them to combine these qualities.

In other words, wool has natural scale 1, crimps, and curls, has a lot of hardness and felting serration, is soft (and has heat retention properties), which other fibers cannot match. However, since the wool fiber itself is elastic, it contains a large amount of air between the fibers, making it too soft to be used in practical use.Therefore, in the present invention, p, θ1 synthetic fiber is used as the primary material. By secondary fusing, the fibers are bound to each other and generally put together, increasing the density between the fibers, and by arranging cotton or floss, this is also slightly bundled by the secondary fusing of P, P, fibers. It has a suitable hardness for use as futon cotton for bedding.Common futons obtained by fusing synthetic fibers together lack warmth and are stiff due to the large number of bonded parts, so this is generally used as a core material. It is used for practical purposes by covering the surface with natural fibers.However,
P, P, fiber itself does not have heat retention properties, but is strong, so in the present invention, it acts as a binder for the heat retention natural fibers, and because of the moisture retention properties of wool, it can be crimped without feeling mixed cooling. , flexibility, and elasticity, and because it is composed of other fibers arranged in a contracted manner, it provides tension and appropriate hardness, and prevents the body from sinking. Especially p, p
The use of fiber makes it soft to the touch, lightweight, and durable, and like wool, it wicks away moisture, making it easy to clean. It is possible to provide a practically similar comfortable futon cotton that also has appropriate elasticity and heat retention.
