Description

Sheet-type fabric detergent using eco-friendly dyeing agent including bleach and softener

The present invention relates to a sheet-type textile detergent using an eco-friendly dye, and more particularly, to simultaneously solve the high cleaning power, bleaching, and fabric softening effects of a non-woven fabric-type textile material so that it can be cut to a predetermined size to inject an appropriate amount of detergent into the laundry. It relates to a sheet-type textile detergent using an eco-friendly dyeing agent including a bleach and a softening agent that is impregnated with a detergent active ingredient that is capable of being combined with a non-woven fabric fiber.

Laundry detergent is a generic term for substances used in the washing process, and includes a detergent that separates foreign substances contaminated with fibers, a bleach to create a brighter color for fibers, and a fabric softener that softens or restores fibers to their original state.

There are two main types of bleach: chlorine-based bleach and oxygen-based bleach. Chlorine-based bleaching agent is sodium hypochlorite (NaClO) a hypochlorite bleaching action by generating free radicals that occur when the main component was a dissolved in water, and oxygen-based bleaching agent and sodium carbonate _{(2Na 2 CO 3 · 3H 2} O 2) is As the main ingredient, hydrogen peroxide, which is decomposed when dissolved in water, generates active oxygen and acts as a bleaching agent.

Fabric softeners contain cationic surfactants to soften fibers whose texture has been altered during washing, and to prevent static electricity from negatively charged fibers.

The sheet-type laundry detergent is composed of non-woven fabric fibers randomly in three dimensions. Detergent powder is impregnated in the pores between the fibers and can be maintained in the form of a sheet by bonding between the non-woven fibers and the detergent. The non-woven fabric fibers and detergent are dissolved and have a cleaning action.

Existing laundry detergent is in powder or liquid form and is used by putting it through a measuring cup or container. It is recommended to use an appropriate amount depending on the amount of laundry. In the case of a small amount, washing is not performed properly, and if an excessive amount is added, not only a loss of detergent but also environmental pollution is caused, which is undesirable from an environmental point of view.

In particular, powder-type detergents can be easily wetted by moisture in the air and harden into lumps, and can cause contamination around the time of input. In addition, there is a problem that the lumped detergent is not easily dissolved in water, so that residues may remain even after washing is completed.

In order to solve these problems, liquid detergents are sometimes manufactured in the form of vesicles or pouches, but they do not satisfy the fast solubility required for use and have storage problems such as bursting during transport.

Most laundry detergents in powder or liquid form are marketed in packaging containers with a capacity of 1 to 5 kg, which is heavy and inconvenient for housewives.

In addition. Laundry detergent used at home consists of three types of detergent, bleach, and softener, and it is inconvenient to increase the number of inputs because it is separately added in each washing process.
