Abstract

The present invention related to the technological field of washing process of textile articles in general.

• • The washing process here revealed can, by the orderly execution of its steps, separate physically part of the “standard detergent” particles defined on ordinance 185 from Inmetro, of Sep. 15, 2015, making the “detergent type A” to reach first the proteinaceous soils, and together, with perborate having bigger and more dense particles it is laid up on the bottom of the washing basket, needing to be taken inside the basket by the water flow generated by mechanic stirring of washing machine. Consequently, the process of perborate being dissolved and interacting with “detergent type A” enzymes.

Claims

1. Washing process including step of proteinaceous soils removal, capable of implement on washing machines, CHARACTERIZED by the fact that comprises, at least, the following sub-steps:

(A) Introduction of textile articles to be washed inside the washing basket;

(B) Filling the washing basket until reaches between 45% to 65% of the water column selected with aqueous solution with level of hydrogenionic potential (pH) between 5 and 7;

(C) Maintenance of textile articles submerged on the aqueous solution with hydrogenionic potential level (pH) between 5 and 7 during at least 90 seconds;

(D) Introducing the washing inputs on the aqueous solution to alter the hydrogenionic potential level (pH) for between 10 and 13;

(E) Adding the mechanical stirring means of the washing machine to generate friction between the textile articles and at least one portion of the washing basket; and

(F) Introduction, again, of an aqueous solution with hydrogenionic potential level (pH) between 5 and 7 until reaches 100% of water column level selected.

2. Washing process including step of proteinaceous soils removal, according to claim 1, CHARACTERIZED by the fact that the aqueous solution of step (B) comprises pure water.

3. Washing process including step of proteinaceous soils removal, according to claim 1, CHARACTERIZED by the fact that the washing inputs of step (D) comprises a formulation mainly composed by base powder blown with enzyme and foam inhibitor, tetra hydrate sodium perborate and bleach activator tetra acetyl ethylene diamine.
