Problems solved by technology

The above two methods cover two methods of anti-felting treatment. The former introduces grafting groups on the wool surface, and the hand feeling of the fabric will be significantly affected by the existence of the coating, while the latter will inevitably lead to relaxation of the fiber structure. , which is not conducive to the shape retention of hollow fabrics

Embodiment 1

[0024] The air-permeable and warm-keeping air layer fabric of embodiment 1 is bonded or sewed by the hollow fabric and the air layer auxiliary material, and the preparation method of the hollow fabric comprises the following steps:

[0025] S1: Immerse the dry wool fabric in the ionic liquid containing soluble rare earth chloride lanthanum chloride, heat in microwave for 2 minutes, cool down to room temperature, keep it for 20 minutes, take out the wool fabric, wash it with ethanol, and dry it; the ionic liquid and chloride The weight ratio of rare earth is 1:0.0005.

[0026] S2: Configure the chitosan zinc sol finishing solution. The main components of the chitosan zinc sol finishing solution are chitosan, zinc dioxide, organic polyacids, and water. The pH of the chitosan zinc sol finishing solution is 3.5. The percentage by weight of chitosan in the polysaccharide zinc sol finishing solution is 0.5%, and the zinc content of the chitosan zinc sol finishing solution is 1.5%; ...

Embodiment 2

Abstract

The invention discloses a breathable and warm air layer fabric which is formed by bonding or sewing a hollowed-out fabric and air layer auxiliary materials. The preparation method of the hollowed-out fabric comprises a wool fabric pretreatment step, a chitosan zinc sol finishing liquid preparation step, a finishing step, a baking and drying step and the like. The breathable and warm air layer fabric is formed by bonding or sewing the hollowed-out fabric and the air layer auxiliary materials; the fabric is good in moisture permeability and thermal insulation property; and in the preparation process of the fabric, wool is pretreated by an ionic liquid, and the wool fabric is finished by a chitosan zinc sol finishing liquid. Condensation reaction is carried out between the components in the finishing liquid, and a film with certain rigidity is formed on the surface of the wool fabric in a crosslinking manner, so that the wool fabric has anti-felting performance and prevents the tendency that wool fibers restore the normal position; the wool fabric tends to be compact in microstructure; the wool fabric at orifices is not easy to fluff after laser punching treatment; and the punched hole pattern is stable.

Description

technical field [0001] The invention relates to the technical field of fabrics, in particular to a breathable and warm air layer fabric. Background technique [0002] Hollow fabrics are divided into two types according to the way of forming holes: one is made by setting weaving method, and the other is made by laser punching. Hollow fabrics are mostly found in fabrics made of synthetic fibers, such as chiffon, polyester, etc. Unfinished wool fabrics will shrink when they are continuously squeezed and rubbed in water, which will cause changes in the punching shape of the hollow fabrics , and the wool around the punching hole is easy to fluff, the accumulation of the above-mentioned changes will affect the appearance and wearing performance of the fabric, which limits the application field of wool to a certain extent. The reason for the felting of wool fabrics is traditionally believed to be mainly caused by the directional friction effect caused by the wool scale layer struc...
