Problems solved by technology

However, the surface of the needle-punched cotton produced through the above-mentioned process is relatively smooth and hard, and the inside of the cotton layer is soft. When it is used as a filling material for furniture or quilts, most of the surface of the needle-punched cotton will stick to the cover, resulting in poor ventilation. , prone to mildew when the air humidity is high
And because the surface is smooth, it will slip with the face cover after long-term use, and it is easy to agglomerate, which will affect the performance of the product

Embodiment 1

[0010] The preparation method of the special-shaped surface needle-punched cotton of the present embodiment, concrete steps comprise:

[0011] The cotton fiber is mixed, opened, carded, screened, pre-punched, stabbed down, stabbed up, and dried in an oven. The heating method of the oven is double-layer electric heating, the temperature is 180°C, and the time is 20 seconds. , the surface is shaped by a shaping roller with a regular irregular concave-convex structure, and then the surface of the cotton layer is instantly cooled by strong cold air to achieve the shaping effect.

[0012] After shaping, the cotton fibers evenly spread on the surface of the needle-punched cotton will form a special-shaped surface structure with different shapes, unevenness and distinct layering. The thickness of the special-shaped cotton layer of the needle-punched cotton accounts for 15% of the total thickness of the needle-punched cotton. Needle-punched cotton with a special-shaped surface has gre...

Abstract

The invention relates to a preparation method of special-shaped-surface acupuncture cotton, which comprises the following steps of carrying out cotton mixing, opening, carding, net arrangement, pre-puncturing, downward puncturing, upward puncturing and baking-oven baking and drying, wherein the heating mode of a baking oven is double-layer electrical heating, the temperature is controlled at 180 to 190 DEG C, and the time is 15 to 20 seconds; shaping through a shaping roller which is provided with a regular special-shaped concave-convex structure on a surface after baking, and then instantaneously cooing the surface of a cotton layer through strong cold air to achieve the effect of shaping. In the preparation method of the special-shaped-surface acupuncture cotton, special-shaped-surface structures with different shapes, unevenness and vivid layering are formed on the surface of the acupuncture cotton by adding a shaping working procedure after heat pressing, so that the air permeability, the pressure resistance and the anti-sliding property of the special-shaped-surface acupuncture cotton are greatly enhanced, and the special-shaped-surface acupuncture cotton has the advantages of soft and fluffy cotton body, good warmth-retaining property, air permeability, good skin-friendly property, difficulty in sliding and clustering and the like when being filled in bedding and clothing as well as furniture; moreover, the double-layer electrical-heating baking oven is adopted on a production process, so that the cotton body is more uniformly heated, and therefore the utilization ratio of heat energy is high.

Description

technical field [0001] The invention relates to the field of improving the processing technology of needle-punched cotton, in particular to a method for preparing needle-punched cotton with a special-shaped surface. Background technique [0002] Needle-punched cotton has a wide range of uses. It can be used not only as filling material for clothing, clothing, cushions, and household items, but also as interior wall decoration. In actual production, needle-punched cotton is made by processes such as cotton blending, opening, carding, netting, pre-punching, down-punching, up-punching, hot pressing, winding, and baling. However, the surface of the needle-punched cotton produced through the above-mentioned process is relatively smooth and hard, and the inside of the cotton layer is soft. When used as a filling material for furniture or quilts, most of the surface of the needle-punched cotton will stick to the cover, resulting in poor ventilation. , Mildew is prone to occur when...
