Embodiment 1

[0020]In this embodiment, a production method of using fruit natural dyes for garment dyeing, taking 5000 pairs of underwear made of a (50s Modal + 30D spandex) fabric as an example, illustrates the method of using fruit dyes to produce natural dyed underwear: first Choose dragon fruit and mangosteen, which grow in nature and are rich in pigments, as dyes. After washing the fruits, extract the natural dye solution without adding any chemical additives and dyes (including mordants); choose high-efficiency refining agents, compare The traditional process prolongs the refining time by 30%, raises the refining temperature to 110°C for pre-treatment of gray cloth; after pre-treatment of gray cloth to obtain white cloth, cut out the size of about 1.5m*1.5m from the white cloth, and use an anti-dyeing pen to draw on the length Draw a square of 1m*1m in the two directions of width and width. According to the corresponding garment dyeing process requirements, this piece of cloth is dyed...

Embodiment 2

[0022] In this example, a production method of using fruit natural dyes for garment dyeing, taking 3000 sweaters made of a 40s pure cotton knitted fabric as an example, illustrates the method of using fruit dyes to produce naturally dyed sweaters: first choose nature Pigment-rich strawberries and pomegranates are used as dyes. After washing the fruits, the natural dyeing solution is obtained through extraction without adding any chemical additives and dyes (including mordants). Then cold stack, wash, and pre-treat the gray cloth; after the white cloth is obtained through the pre-treatment of the gray cloth, cut out a size of about 1.5m*1.5m from the white cloth, and draw a 1m in the length and width directions with an anti-dyeing pen *A square of 1m, according to the corresponding garment dyeing process requirements, this piece of cloth is placed in a garment dyeing vat (air-flow dyeing vat for dyeing cloth) like clothes, and the size changes after dyeing, and the length direct...

Embodiment 3

[0024] In this embodiment, a production method of using fruit natural dyes for garment dyeing, taking 2000 pieces of home clothes made of 21s Modal fabric as an example, illustrates the method of using fruit dyes to produce natural dyed home clothes: first choose nature Pigment-rich wild berries and coconuts are used as dyestuffs. After washing the fruits, the natural dyeing solution is obtained through extraction without adding any chemical additives and dyes (including mordants); 100% refining time, increase the refining temperature to 90°C for gray cloth pre-treatment, after the gray cloth pre-treatment to get white cloth, cut the size of about 1.5m*1.5m from the white cloth, use the anti-dyeing pen on the two sides of the length and width Draw a square of 1m*1m in two directions, and according to the requirements of the corresponding garment dyeing process, put this piece of cloth in the garment dyeing vat (air overflow dyeing vat for dyeing cloth) like a garment and dye it...

Abstract

The invention discloses a production method for carrying out garment dyeing by utilizing a fruit natural dyestuff. According to the production method, fruits with high pigment content are selected asraw materials of natural dyeing, and any chemical auxiliary agent and any dyestuff are not added; after the garment dyeing is selected, dehydration and drying are carried out; then water washing is carried out; then secondary drying is carried out; then the garment dyeing is carried out through selecting a dyeing vat with a dyeing channel having a relatively great pipe opening diameter. The methoddisclosed by the invention has the beneficial effects that a production process has the advantages of low carbon and environment protection; a novel fruit natural dyeing technology is used for replacing a traditional chemical dyeing technology; fruit dyed garments produced by the method disclosed by the invention have good quality, are green and healthy and have a good market prospect.

Description

technical field [0001] The invention relates to the field of clothing, in particular to a production method for dyeing garments with natural fruit dyes. Background technique [0002] Colored garments can be produced through yarn dyeing, cloth dyeing and garment dyeing. Garment dyeing is traditionally produced by dyeing with chemical dyes. This chemical dyeing method pollutes the environment and is not conducive to consumer satisfaction. Dress healthy. Some technicians have used natural dyes to carry out research and production of garment dyeing without using chemical auxiliaries at all. As a result, the color fastness is not up to standard, and color flowers appear in the dyeing. There are serious chromatic aberration and other problems. The main reason for these problems is that without the use of chemical auxiliaries, natural dyes have low fixation to fabric fibers and poor dyeing levelness. In addition, the traditional garment dyeing equipment has a small dyeing vat cap...
