Description
Technical Field
The utility model relates to the technical field of wool flakes, in particular to a wool flake with a sandwich structure.
Background
Wool is widely used as a natural animal fiber in household clothing articles such as clothing and bedding. Wool quilt is also a common bedding in the market, and has the advantages of moisture absorption, dryness retention, dust prevention and electricity resistance. However, conventional wool batts have problems of boring and unhairing when used as a quilt core. The conventional method for solving the problem of wool flock drilling is to provide a layer of non-woven fabric on the outer side of the wool flock, but the conventional non-woven fabric is also of a porous structure, and fibers are connected through physical entanglement, so that if the wool flock is bonded by using a chemical adhesive, injury to a user can be caused.
How to prepare a wool batt with good anti-drilling properties and without the use of chemical binders is a problem to be solved.

Detailed Description
The utility model will be further described with reference to the drawings and specific examples.
Example 1
The present embodiment will be described in detail with reference to fig. 1, 2 and 3. The wool flocculus with the sandwich structure comprises a first fiber layer 1, a wool fiber net 2 and a second fiber layer 3; the first fiber layer 1 and the second fiber layer 3 are made of bicomponent fibers, and the bicomponent fibers are sheath-core bicomponent fibers or side-by-side bicomponent fibers.
Further, the sheath-core bicomponent fiber comprises a sheath layer 11 and a core layer 12; the skin layer has a melting point lower than that of the core layer. Specific alternatives are ES fibers or sheath-core polylactic acid fibers. In this embodiment, ES fibers are selected.
Further, the bicomponent fibers may also be selected as side-by-side bicomponent fibers. The side-by-side bicomponent fiber includes a low melting point portion 13 and a high melting point portion 14 arranged side by side. Specifically, polylactic acid side-by-side bicomponent fibers are selected, the low melting point portion 12 is low melting point polylactic acid, and the high melting point portion 14 is high melting point polylactic acid.
Further, the fleece web 2 is formed by cross-lapping. Can form thicker wool fiber net 2, and has good warm-keeping effect.
When the wool flocculus with the sandwich structure is prepared, three layers of fiber nets are stacked and then needled, so that the three layers of fiber nets can be combined, after needling and combining, a hot roller is adopted to carry out surface treatment, so that the low-melting point part in the fiber net on the surface is melted and is bonded with adjacent fibers, and wool drilling can be effectively avoided.
Example two
This embodiment will be described in detail with reference to fig. 4. One of the differences between the wool wadding with the sandwich structure according to the present embodiment and the first embodiment is that a thermal insulation fiber layer 4 is arranged between the first fiber layer 1 and the wool fiber web 2.
The second difference from the first embodiment is that: a thermal insulation fiber layer 4 is also arranged between the second fiber layer 3 and the wool fiber net 2.
Further, the thermal insulation fiber layer 4 is made of polylactic acid aerogel fibers or hollow fibers. Selected as polylactic acid aerogel fibers in this example.
Example III
This embodiment will be described in detail with reference to fig. 5. The wool flocculus with the sandwich structure comprises a first fiber net 1, an incense type polyester fiber flocculus 5, a wool fiber net 2, a thermal insulation fiber layer 4, the wool fiber net 2, the incense type polyester fiber flocculus 5 and a second fiber net 3 in sequence.
The fragrance type polyester fiber flocculus 5 emits light fragrance along with the body temperature of a human body during sleeping or under pressure and friction, so that the smell of wool is inhibited. The raw materials of the fumigating type polyester fiber flocculus 5 are 85% of 2.5D fumigating type polyester fibers and 15% of 2D low-melting-point cotton.
