Abstract

The invention discloses a method for processing down jacket fabrics that are hot-rolled and bonded instead of seams. (1) A durable waterproof finishing agent is obtained from an organic fluorine water repellent, a blocked isocyanate crosslinking agent, and glacial acetic acid; (2) a defoaming agent is used. , water-based sulfonate type aliphatic polyurethane emulsion, thickener, polyacrylic acid sodium salt dispersant, silica matting powder, nano-calcium carbonate, expandable microsphere powder, cross-linking agent, blocked acid catalyst, to prepare the coating Glue; Nylon or polyester fabric padding finishing, calendering treatment, coating treatment, the fabric feels soft, downproof, waterproof, breathable, washable, cold resistance, so that the down jacket fabric can be hot-rolled to form a grid Between, high bonding strength, free from seams.

Description

technical field [0001] The present invention relates to the finishing technology of textile fabrics, and specifically relates to down jacket fabrics that are processed so that the fabrics can be attached to the special seamless adhesive strips for down jackets to realize hot-rolled lamination, instead of needle and thread seams, and the lamination strength is high , At the same time, the fabric feels soft, and has excellent fleece resistance, water resistance, air permeability, washability, and cold resistance. Background technique [0002] Seam seaming is also called crimping, which is a sewing method, generally made of two (or more) fabrics, with filler added to the middle interlayer, seam seaming is to fix the filling material in a small compartment, so that the filling Substances are held stably within the compartments. Down jacket fabrics generally have linear or rhombus-shaped inter-cell seams, the purpose of which is to fix the filled down, distribute the down evenly...
