Technical Field

The utility model relates to the technical field of heat-insulating linings, in particular to a dress heat-insulating lining.

Background

Most thermal clothes adopt fiber secondary composite aerogel, aerogel composite spinning and EPTFE laminated composite aerogel modes. The secondary composite aerogel fiber has the advantages of unobvious improvement on the heat preservation effect, hard hand feeling and no close fitting. The current technology of the aerogel spinning method is difficult to complete, in the wire drawing process, due to the existence of aerogel, the wire drawing process can be frequently broken and difficult to form wires, so that the final cost is very high, and in addition, in order to ensure the wire forming, the aerogel addition proportion is small, so that the heat preservation effect is poor. The EPTFE laminated composite aerogel is soft and comfortable, and is easy to manufacture, but due to the multi-layer EPTFE laminated structure, the air permeability is poor, and in addition, the coated aerogel material can be scattered by cutting the cut surface in the cutting process.

Detailed Description

The present invention is further described below in conjunction with the following figures and specific examples so that those skilled in the art may better understand the present invention and practice it, but the examples are not intended to limit the present invention.

Referring to fig. 1, in the preferred embodiment of the utility model, a garment thermal insulation lining is disclosed, which comprises a coated fabric 1, a lining core 3 and a liner 5, which are sequentially arranged from outside to inside, wherein the coated fabric 1 and the lining core 3 are pressed through a first hot melt adhesive layer 2, and the lining core 3 and the liner 5 are pressed through a second hot melt adhesive layer 4. The size of the lining core 3 is matched with that of the coating fabric 1 and the liner 5, the lining core is respectively pressed through the first hot melt adhesive layer 2 and the second hot melt adhesive layer 4, and the lining core can be cut to manufacture clothes after the pressing is finished.

Preferably, the lining core 3 is formed by compounding aerogel and PTFE particles, so that the shedding of aerogel powder is avoided.

In some of these embodiments, the aerogel and the PTFE particles are compounded and then calendered and stretched to match the cross-sectional area of the compounded material to the cross-sectional area of the coated fabric and the cross-sectional area of the inner container.

Preferably, the coating fabric 1 is a warp and weft yarn fabric, and the warp and weft yarn fabric is made of high-density silk, cotton cloth, cotton polyester and other cloth materials.

Preferably, the warp and weft fabrics are subjected to rolling treatment to reduce gaps between the warp and weft yarns, and then are coated with polymer slurry to form a cross-linked transparent film covering layer with the warp and weft fabrics, so that the gaps between the warp and weft of the fabrics are closed.

Preferably, the water-proofing agent adopts fluorine phosphorus resin or organic silicon, so that the fabric has the properties of preventing fluff and water seepage.

Preferably, the inner container 5 is made of polyester taffeta, and the polyester taffeta is smooth in hand feeling and suitable for being directly contacted with skin.

Preferably, the surface of the polyester taffeta is also coated with a down-proof coating, so that the condition that the polyester taffeta is easy to rise when the polyester taffeta is always contacted with the skin to cause the skin to feel uncomfortable is avoided.

Preferably, the polyester taffer adopts 190T-290T. The type of the fabric can be based on actual requirements and economic cost, and 190T and 210T are not preferred due to poor hand feeling.

In some embodiments, the first hot melt adhesive layer 2 bonds the warp and weft fabrics and the lining core 3, and since the warp and weft fabrics are porous fabrics, when the adhesive melts, the adhesive penetrates into the pores, and although a certain bonding effect can be achieved, the bonding strength is greatly reduced. The thickness of the first hot melt adhesive layer 2 is slightly larger than that of the second hot melt adhesive layer 4.

Preferably, the thickness of the lining core 3 is 0.5-5 mm. The basic process for manufacturing the lining core 3 is as follows:

(1) taking a certain amount of water, adding a specific dispersing agent, then slowly adding PTFE particles, carrying out defibering and dispersing on the particles, and carrying out 30min at 2500rpm of a high-speed dispersing machine.

(2) After completion of dispersion of the above PTFE, it was filtered and dried (drying temperature: 180 ℃ C.)

(3) The dried PTFE was dry blended with an aerogel (particle size less than 30 μm).

(4) Hot pressing (temperature 300 ℃) is carried out after the drying is finished, and rolling and stretching (stretching temperature 250 ℃) are carried out by adopting specific equipment after the hot pressing is finished

(5) After the stretching is finished, sintering is carried out with tension, and the sintering temperature is 330 ℃. And sintering to obtain the target material.
