preparation example Construction

[0035] In order to solve the above problems, one or more embodiments of this specification provide a method for preparing a waterproof, breathable, machine washable anti-drilling fleece composite fabric, including:

[0036] For the preparation of fiber membranes, add polylactic acid to a mixed solvent of chloroform and acetone, stir and mix evenly to form a polylactic acid solution, and electrospin the polylactic acid solution at a voltage of 10-18kV and a spinning speed of 15-30ml / h Silk, to prepare micro-nano electrospun polylactic acid fiber membrane;

[0037] For the preparation of the composite fabric, the base fabric is taken, the surface of the base fabric is sprayed with glue, and then the micro-nano electrospun polylactic acid fiber film is laminated with the base fabric to obtain a composite fabric.

[0038] At the same time, one or more embodiments of this specification also provide a composite fabric prepared by the preparation method of the waterproof, breathable,...

Abstract

According to a waterproof breathable machine-washable down-proof composite fabric and a preparation method thereof provided by one or more embodiments of the invention, a micro-nano electrospinning fiber membrane with high porosity and low density is compounded with the fabric, and the micro-nano electrospinning membrane is compounded with a cotton fabric, so that the light down-proof fabric is prepared; meanwhile, the fabric has waterproof, breathable and machine-washable functional properties and fills the blank in the market ; and the problem that a traditional down quilt cannot be used for machine washing is solved, and the gram weight of the prepared fabric does not exceed 80 g / m < 2 > and is lower than that of a universal down-proof fabric in the market.

Description

technical field [0001] One or more embodiments of this specification relate to the technical field of composite fabrics, in particular to a waterproof, breathable, machine washable anti-drilling fleece composite fabric and a preparation method thereof. Background technique [0002] As the natural fiber with the strongest thermal performance and the lightest quality, down has been widely used in textiles, clothing, home textile bedding and other fields. The special structure with an acute angle to the down silk leads to the phenomenon of down drilling frequently and "only comes out but not in", which seriously affects the warmth retention rate, bulkiness and consumer experience of down products. [0003] The current methods of preparing anti-drilling fleece fabrics are mainly high-count, high-density calendering and anti-drilling finishing methods. Among them, the high-count, high-density and calendering method specifically uses high-fineness yarns, combined with a tight wea...
