Embodiment 1

[0022] A) Finishing the dyed garments, specifically to distinguish the front and back of the garments before sending them into the stone mill, to ensure that the fronts are facing outwards, the curling parts need to be ironed and smoothed, and the bag flaps are checked to see if they are stitched. Garments with plackets should be temporarily sewn with thread, and for garments without pocket flaps and / or without plackets, the corresponding sewing work can be omitted, and ready-to-wear garments can be obtained;

[0023] B) select pumice stone, preferably adopt the pumice stone that the specification that Indonesia produces is 1.8-2.2 * 1.8-2.2 * 3.8-4.2cm, the pumice stone of specific gravity<1 should account for 9-11%, Mohs hardness control is <2, and The selected part of the pumice is pre-soaked in a container containing a 0.08% potassium permanganate solution, such as a tank, vat, or barrel, for 25-35 minutes, and then taken out and drained for 10-20 minutes to obtain an impre...

Embodiment 2

[0027] The strong oxidizing agent solution in step B) is changed to the sodium hypochlorite solution of concentration 1%; Step C) dry, wet pumice in the machine room of stone mill account for a volume ratio of 40: 1, i.e. dry, wet pumice The occupancy rate is 40%, and the stone grinding time is 12 minutes; in step D), the water is heated to 60°C, and 3g / L of sodium soda is added to wash for 9 minutes. The add-on amount of the clothes is respectively 9%, 2.2%, 1.2% of the weight of the clothes, and the clothes are dehydrated to a water content of 28%, and feed into the cold wind for 26min, and all the other are the same as the description of embodiment 1.

Embodiment 3

[0029] Change the concentration of the potassium permanganate solution in step B) to 2%; Step C) in the dry and wet pumice in the machine storehouse of the stone mill account for a volume ratio of 35: 1, that is, dry and wet pumice The occupancy rate is 35%, and the stone grinding time is 8 minutes; the clear water in step D) is heated to 65°C, and 4g / L of oxalic acid is added to wash for 10 minutes, the amount of soda ash added is 1g / L, cotton softener, fluffy agent, silicone oil The addition amount of the clothes is respectively 8.5%, 2.5%, 1.5% of the weight of the clothes, and the clothes are dehydrated to a moisture content of 27%, and feed into the cold wind for 27min, and all the other are the same as the description of embodiment 1.

Abstract

A method for aging the clothes after dying process comprises that: cleaning the dyed clothes; selecting pumex and putting some pumex into strong oxidant solution to be immerged, taking out and drying, to obtain wet pumex; putting dry and wet pumexes into the chamber of grinder; putting clothes into chamber, grinding and taking out clothes to obtain the grinded aged clothes; washing that washing clothes in washing machine, leading in clean water, heating, adding oxalic acid or sodium thiosulphate to wash and adjust pH value, discharging water, leading in water, adding sodium thiosulphate, neutralizing and washing, controlling pH value, softening, dewatering, drying, cleaning to obtain the final product. The inventive clothes have soft, flexile and wet-adsorption properties.

Description

technical field [0001] The invention relates to a method for returning old knitted garments after dyeing treatment, and belongs to the technical field of post-treatment of cotton fabrics. Background technique [0002] Cotton knitted garments (also known as cotton knitted sweaters) are the best-selling garments in the world because of their good air permeability, soft touch, hygroscopicity and elasticity, and the absence of annoying static electricity and environmental protection. One of the varieties, but also gradually tends to be worn outside from the traditional use as underwear. However, under the influence of denim garments, cotton knitted garments cannot be compared with denim garments because they do not have a washed-out feel, thus restricting the outer wear of cotton knitted garments. Although all-cotton knitted garments have the advantages of long-lasting bright color retention effect and economical price and are suitable for popular wear, if they cannot be given ...
