Embodiment 1

[0024] An anti-drilling nonwoven fabric for a down jacket, which sequentially includes a waterproof breathable layer, a nonwoven fabric layer and an inner lining layer from outside to inside; in terms of mass percentage, the waterproof breathable layer includes 30-40% polymer waterproof breathable film and 60-70% silk fabric; in terms of mass percentage, the non-woven fabric layer includes 60-80% polyester and 20-40% conductive fiber; the inner lining layer is cotton fabric.

[0025] A preparation method for down wear anti-drilling down nonwoven fabric as described in any one of the above, comprises the following steps:

[0026] Step S1: The polymer waterproof and breathable membrane and the silk fabric are interlaced and compounded in proportion to form a multi-layer composite waterproof and breathable layer, which is ready for use;

[0027] Step S2: Arranging the polyester and the conductive fibers evenly in proportion, then fixing and bonding them to form a non-woven fabric...

Abstract

The invention relates to a downproof nonwoven fabric for a down jacket. The downproof nonwoven fabric orderly comprises a waterproof breathable layer, a nonwoven fabric layer and a lining layer from outside to inside; in mass percent, the waterproof and breathable layer comprises 30-40% of macromolecule waterproof and breathable film and 60-70% of silk fabrics; the nonwoven fabric layer comprises60-80% of terylene and 20-40% of conductive fiber; and the lining layer is cotton fabric. By arranging three layers of fabrics for the down jacket, the protection effect of the whole down jacket fabric is enhanced, and the downproof effect of the down jacket fabric is better; by adding the macro-molecular water and breathable film in the waterproof and breathable layer, the outermost layer of thedown fabric is waterproof and breathable when the downproofness is reached, and the hand feeling of the outer layer fabric is more silky after combining with the silk fabric.

Description

technical field [0001] The invention belongs to the technical field of down fabrics, and in particular relates to an anti-drilling down nonwoven fabric for down clothing. Background technique [0002] Down is flower-shaped, light in weight, highly elastic, and smooth. It is the best natural thermal insulation material in the world and is widely used to make down jackets, duvets, and mattresses. Due to the silky properties of down, if it is directly placed in the fabric as a thermal insulation material, there will be velvet overflowing from the pores of the fabric, affecting the overall appearance, and the flying velvet drilled out will also give people an uncomfortable feeling When making down products, it is necessary to wrap the anti-drilling down material outside the down to prevent the down from drilling out. [0003] Most of the down jacket fabrics currently on the market have the effect of anti-drilling down, but while enhancing the anti-drilling effect of down fabric...
