Embodiment 1

[0023] A) Finish the finished garment after dyeing. Specifically, make sure that the front and back of the finished garment are distinguished before being sent to the stone mill. Make sure that the front is facing outwards. The curling part needs to be ironed and flattened. Check whether the bag cover is sewn or not. Garments with plackets should be temporarily stitched with threads. For garments without flaps and / or plackets, the corresponding sewing operations can be omitted to obtain the garments to be ground;

[0024] B) Select pumice stone, preferably 1.8-2.2×1.8-2.2×3.8-4.2cm pumice made in Indonesia. Pumice with a specific gravity of <1 should account for 9-11%, and the Mohs hardness should be controlled to <2, and The selected part of the pumice is pre-soaked in a container such as a tank, vat, or barrel containing a potassium permanganate solution with a concentration of 0.08% for 25-35 minutes, and then taken out and drained for 10-20 minutes to obtain an impregnated pot...

Embodiment 2

[0028] Change the strong oxidant solution in step B) to a sodium hypochlorite solution with a concentration of 1%; in step C), the volume ratio of dry and wet pumice in the chamber of the stone mill is 40:1, that is, dry and wet pumice The occupancy rate is 40%, and the stone grinding time is 12min; in step D), the clean water is heated to 60℃, and 3g / L of soda is added to clean for 9min. The amount of soda ash is 0.9g / L, softener, fluffing agent, silicone oil for cotton The added amount is 9%, 2.2%, 1.2% of the weight of the garment. The garment is dehydrated to a moisture content of 28%, and cold air is introduced for 26 minutes. The rest is the same as described in Example 1.

Embodiment 3

[0030] Change the concentration of the potassium permanganate solution in step B) to 2%; the volume ratio of dry and wet pumice in step C) in the chamber of the stone mill is 35:1, that is, dry and wet pumice The occupancy rate is 35%, the stone grinding time is 8min; the clean water in step D) is heated to 65℃, and 4g / L oxalic acid is added for cleaning for 10min, the soda ash content is 1g / L, cotton softener, fluffing agent, silicone oil The added amount is 8.5%, 2.5%, 1.5% of the weight of the garment. The garment is dehydrated to a moisture content of 27%, and cold air is introduced for 27 minutes. The rest are the same as those described in Example 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 restoring an old knitted garment after dyeing treatment, and belongs to the technical field of cotton fabric post-treatment. Background technique [0002] Because cotton fabric has good air permeability, soft hand, moisture absorption and elasticity, and does not have annoying static electricity phenomenon and is environmentally friendly, cotton knitted garments (also known as cotton knitted sweaters) are the world's best-selling garments One of the varieties, but also from the traditional wear as underwear gradually tends to wear outside. However, under the influence of denim garments, cotton knitted garments cannot be compared with denim garments because they do not have a washed-out feeling, which restricts the outer wear of cotton knitted garments. Although all-cotton knitted garments have the advantages of long-lasting color retention and economical price, which are suitable for popular wear, if they can not be giv...
