Description

Feather-like bedding

technical field

The utility model relates to a kind of feather-like bedding, in particular to a filling material for the bedding.

Background technique

There are many kinds of filling materials used to make bedding. Natural fiber raw materials mainly include down, cotton, silk waste, etc. Synthetic fiber raw materials mainly include polyester three-dimensional crimped fiber, fine denier polyester fiber, etc. Among them, polyester three-dimensional crimped fiber is widely favored by people because of its good elasticity and bulkiness, low price, and not easy to mildew.

Natural fiber raw materials such as down, cotton, and silk waste are used as filling materials, which have defects such as high cost, limited material output, poor fiber compression resistance, poor durability, and easy mildew. The wadding fiber launched by DuPont Company of the United States makes polyester staple fiber into four-hole hollow and seven-hole hollow fibers. The surface of these fibers is covered with a silicone film, which can reduce silkiness and smooth hand feeling. It is known as super down and breathing cotton. . However, three-dimensional crimped polyester staple fibers also have certain problems as filling materials. For example, the filled quilts and clothing are too fluffy, resulting in too large gaps between fiber materials, which are not close to the body when used, and cannot achieve the comprehensive performance of comfort and warmth like cotton.

At present, the product structure of bedding has overproduction of middle and low-end products, high technical content, and low proportion of high value-added products, which cannot meet the needs of consumers in dormitory culture after entering a well-off society. It is predicted that in the next 10 years, the bedding industry will become one of the most promising industries in the textile industry.

Contents of the invention

The technical problem to be solved by the utility model is to design a feather-like bedding to overcome the defects in the prior art and meet people's needs.

The feather imitation bedding of the present utility model comprises a coat and a filling material filled in the coat, the filling material is composed of a fiber body and a dot-shaped bonded body, the fiber bodies are interlaced, and its ends The point-shaped adhesive bodies are connected to form a three-dimensional three-dimensional network.

Bedding includes sleeping bags, cushions, clothing linings, quilts or toys, etc.

The feather-like bedding of the utility model has down-like soft feel, excellent heat retention and air permeability, excellent fluffing effect, easy surface treatment, excellent hand feeling smoothness, high light weight, less difficult post-processing technology, and low cost. Greatly reduced. Compared with other synthetic fiber fillings, it has obvious advantages. The down-like bedding is light, soft, fluffy and comfortable, and has good elasticity, making it very suitable for replacing down, cotton, silk, etc. as filling materials.

Description of drawings

Fig. 1 is a structural schematic diagram of down-like bedding.

Figure 2 is a schematic diagram of the structure of the filling material.

Detailed ways

Referring to Fig. 1 and Fig. 2, the feather-like bedding of the present utility model comprises a coat 1 and a filling material 2 filled in the coat 1, said filling material 2 is composed of a fiber main body 3 and a dot-shaped bonding body 4, The fiber main bodies 3 are intertwined with each other, and the ends thereof are connected with point-shaped bonding bodies 4 to form a three-dimensional three-dimensional network.

The material of the fiber body 3 is fine denier silicone polyester fiber, and the material of the dot-like bonding body 4 is low melting point bonding fiber, also called hot-melt fiber; the fineness of the fine denier silicon polyester is 0.4D-1D, and the fiber length 5 ~ 60mm;

The weight content of fine denier silicone polyester fiber is 70-92%, and the weight content of low melting point bonding fiber is 8-30%;

The utility model is prepared like this:

After the fine denier silicon fiber and low melting point bonded fiber are loosened by the opener, the two fibers are mixed evenly in the mixer according to a certain weight ratio, and then the mixed fiber is fed into the opener for further opening and mixing. The dense-needle combing process combs the mixture of two fibers, mechanically lays the web or air-laid, and heat-drying can use non-glue cotton heat-drying equipment. The surface is melted, and after cooling, the intersecting points of the fiber web are solidified to form a fixed three-dimensional network structure with silicon fibers.

Using this process, the hot-melt cotton has high strength, no glue, high adhesion, and good durability; its thickness uniformity error is less than 3g/m ² , and its weight and warmth are comparable to down.

The filling material of the utility model adopts the composite immersion type silicone oil coating process, and the oil is oiled twice to increase the crimp, so as to ensure the fine denier yarn height ratio surface oil quantity, and the silicone oil coated has high smoothness and high uniformity. The fiber setting adopts static pressure laminar flow method, and the high temperature process ensures that the fine denier silicon fiber has good bulkiness, good combability, high strength and strong compression resistance.

It is made of fine denier silicon fiber and hot-melt fiber through dense needle combing process. The hot-melt cotton has high strength, no glue, high adhesion and good durability; its thickness uniformity error is less than 3g/m ² , The grammage and warmth retention are comparable to the down of above. The product performance of bulk fiber filling reaches the comprehensive value of down and hollow.
