Description

Down quilt

Technical Field

The utility model belongs to the technical field of the eiderdown quilt, concretely relates to eiderdown quilt.

Background

The down quilt is a quilt filled with down filling, and has a large appearance and good heat preservation performance. The eiderdown quilt still has light pleasing to the eye characteristics for traditional quilt, receives consumer's favor deeply, generally sew together the interior down layer of preventing of eiderdown quilt and outer down layer of preventing through the quilting line among the prior art to fill the fine hair space through crisscross formation between the quilting line, however, the eiderdown quilt of traditional method preparation through sewing up must can leave the pinhole in sewing up the department, and for a long time, the eiderdown can run out from the pinhole, thereby influence the cold-proof effect and the appearance pleasing to the eye of eiderdown quilt, therefore we need a neotype eiderdown quilt to solve above-mentioned problem, satisfy people's demand.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a down quilt to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the down quilt comprises an outer down prevention layer and an inner down prevention layer, wherein cloth strips are connected between the outer down prevention layer and the inner down prevention layer through strip-shaped hot melt adhesives, a down filling channel is formed between every two adjacent cloth strips and used for filling down, and the strip-shaped hot melt adhesives are composed of a bottom sizing layer and an adhesive powder layer.

Preferably, the strip-shaped hot melt adhesive is coated on the inner surfaces of the inner down-proof layer and the outer down-proof layer in a mechanical spraying mode.

Preferably, the primer layer is an EVA resin obtained by copolymerizing ethylene and vinyl acetate at high temperature and high pressure.

Preferably, the gummed powder layer is formed by mixing a tackifier such as rosin or modified rosin and an antioxidant.

Preferably, the outer pile-proof layer and the inner pile-proof layer are made of nylon silk or TC cloth with yarn count density of more than 230T.

Preferably, the thickness of the strip hot melt adhesive is 0.5-1 mm.

Preferably, the cloth strips are rectangular cloth strips which are mechanically cut, and the sizes of the cloth strips are uniform.

The utility model discloses a technological effect and advantage: the down quilt can effectively reduce the phenomenon of feather leakage of the down quilt, adopts special fabrics, and is attractive and durable.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model provides a down quilt as shown in figure 1, figure 2 and figure 3, including preventing fine hair layer 2 and interior fine hair layer 1 of preventing outward, prevent outward that fine hair layer 2 is connected with cloth 4 with interior down layer 1 of preventing through strip hot melt adhesive 3 between, and form between two adjacent cloth 4 and fill the fine hair passageway and be used for filling fine hair, strip hot melt adhesive 3 comprises primer layer 5 and rubber powder layer 6.

Specifically, the strip-shaped hot melt adhesive 3 is coated on the inner surfaces of the inner down-proof layer 1 and the outer down-proof layer 2 in a mechanical spraying mode.

Specifically, the primer layer 5 is EVA resin obtained by copolymerizing ethylene and vinyl acetate at high temperature and high pressure.

Specifically, the gummed powder layer 6 is formed by mixing a tackifier such as rosin or modified rosin and an antioxidant.

Specifically, the outer pile-preventing layer 2 and the inner pile-preventing layer 1 are made of nylon silk or TC cloth with yarn count density of more than 230T.

Specifically, the thickness of the strip-shaped hot melt adhesive 3 is 0.5-1 mm.

Specifically, the cloth strips 4 are rectangular cloth strips which are mechanically cut, and are uniform in size.

The working principle is as follows: in the production process of the down quilt, the strip-shaped hot melt adhesive 3 is formed by firstly coating slurry on corresponding positions of an inner down-proof layer 1 and an outer down-proof layer 2 in a mechanical spraying mode according to needs to form adhesive strips, then spreading adhesive powder on the adhesive strips and sucking away redundant adhesive powder, attaching the strip-shaped hot melt adhesive 3 at two side edges of a cloth strip 4 and connecting the cloth strip 4 between the outer down-proof layer 2 and the inner down-proof layer 1 in a hot pressing mode to form a plurality of down filling channels, and sealing the down filling channels by the strip-shaped hot melt adhesive 3 after filling down.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
