Air interlayer quilt and manufacturing technology thereof

Abstract

The invention discloses an air interlayer quilt and a manufacturing technology thereof. The air interlayer quilt is manufactured by wrapping quilt batt with a quilt cover; the quilt batt is composed of outer wrapping cotton layers, supporting columns and a seal film bag, the seal film bag is filled with air and wrapped by the outer wrapping cotton layers, the supporting columns penetrate through penetrating holes in the seal film bag, and the two ends of each supporting column are fixedly connected with the inner surfaces of the outer wrapping cotton layers respectively; each outer wrapping cotton layer is made of raw cotton, polynosic, viscose acetal fiber, silk, spandex fiber, rabbit hair, sheep wool and polyester fiber; each supporting column is made of raw cotton, polyvinyl alcohol fiber, polyvinyl chloride fiber, coconut fiber and polyacrylonitrile fiber. The air interlayer quilt is low in weight, and the seal film bag in the quilt batt effectively prevents the quilt from deforming; the seal film bag is filled with the air, so that the quilt is high in rebound resilience, and due to the water resistance of the seal film bag, the quilt batt has good dampproof performance.

Description

technical field [0001] The invention relates to a quilt and its manufacturing process, in particular to an air interlayer quilt and its manufacturing process. Background technique [0002] Cotton quilts, duvets, silk quilts, wool quilts and chemical fiber quilts are one of the quilts commonly used by people. Down quilts have the advantages of lightness, softness and good warmth retention. But down products also have many deficiencies: [0003] 1. The use of down as a filling material has higher requirements on the fabric, otherwise the phenomenon of down drilling will be very serious; [0004] 2. Coated high-density fabrics are generally used as duvet covers. This kind of fabrics are mostly chemical fiber fabrics. In winter, the electrostatic phenomenon is serious and the comfort is poor; [0005] 3. The duvet is bulky, bloated, and inconvenient to carry and store. One of the biggest disadvantages of duvets is that they are poorly resistant to moths and mildew, and insect...

AI Technical Summary

Problems solved by technology

[0004] 2. Coated high-density fabrics are generally used as duvet covers. This kind of fabrics are mostly chemical fiber fabrics. In winter, the electrostatic phenomenon is serious and the comfort is poor;

[0005] 3. The duvet is bulky, bloated, and inconvenient to carry and store

Their disadvantages are poor wear resistance, heat resistance, hygroscopicity, and air permeability.

[0009] Compared with quilts such as down, silk, and wool, the cotton quilt has the advantages of good warmth retention, softness and comfort, and the cotton quilt has no static electricity, which is beneficial to people with cardiovascular diseases and infants. , easy to deform, poor resilience, and easy to be damp, and the warmth retention of the current quilts needs to be further improved
