Method for manufacturing cleaning cloth

Abstract

A method includes a preparing step including providing a substrate made of high-density woven cloth, a scouring step including scouring the substrate, a sanforizing step including sanforizing the substrate at a high temperature, a brushing step including brushing the substrate to form a layer of fluff on the substrate, a water repelling treatment step including applying a water repellent on the substrate to fully blend the water repellent into fibers of the substrate, a calendering step including performing a calendering treatment to pressurize the substrate at a high temperature, to shorten and fill a gap between the fibers of the substrate by the fluff, and a waterproof treatment step including applying a waterproof agent on the substrate to form the cleaning cloth.

1 . A method for manufacturing cloth, comprising:
 a preparing step including providing a substrate made of woven cloth;   a scouring step subsequent to the preparing step including scouring the substrate to remove oil, sizing agent, and dirt from the substrate;   a sanforizing step subsequent to the scouring step including sanforizing the substrate at a high temperature so that the substrate has a determined amount of shrinkage in a warp direction and a weft direction, to reduce a water shrinkage;   a brushing step subsequent to the sanforizing step including brushing the substrate to form a layer of fluff on a surface of the substrate;   a water repelling treatment step subsequent to the brushing step including applying a water repellent on the substrate to fully blend the water repellent into fibers of the substrate;   a calendering step subsequent to the water repelling treatment step including performing a calendering treatment to pressurize the substrate at a high temperature, to shorten a gap between the fibers of the substrate, and to fill the gap between the fibers of the substrate by the fluff; and   a waterproof treatment step subsequent to the calendering step including applying a waterproof agent on the substrate to form the cloth;   wherein:   the preparing step, the scouring step, the sanforizing step, the brushing step, the water repelling treatment step, the calendering step, and the waterproof treatment step are serially performed in sequence;   the water repelling treatment step includes coating the water repellent on the substrate;   the waterproof treatment step includes impregnating the substrate in the waterproof agent; and   the waterproof agent is made of polyurethane (PU).
