Problems solved by technology

pH-sensitive synthetic dyes usually have hazards such as toxicity and sensitization, and cannot be directly applied to textiles for consumption
At the same time, some acid-base color-changing indicators cannot be used repeatedly, and the range of acid-base indication is small, which greatly limits the scope of application.

Embodiment 1

[0042] A method for dyeing clothing with intelligent sweat acid-base discoloration, comprising the following steps:

[0043] 1) Pre-dyeing treatment: soak the cotton fabric or cotton label sample in dimethyl sulfoxide (DMSO) solution at room temperature for 1 hour before dyeing.

[0044] 2) Dyeing:

[0045] Dyeing formula: Benthic algae natural raw material concentrate is 2% relative to the weight of the fabric; dimethyl sulfoxide; NaHCO3 / Na2CO3 buffer solution with pH=8;

[0046] When dyeing, select 2% benthic algae natural raw material concentrate relative to the fabric weight, mix the soaking solution (DMSO) and water one to one as the dyeing solution, control the bath ratio at 1:30, and combine it with ultrasonic waves (300W, 26KHZ) To achieve mordantless dyeing, the temperature is 45°C, and the dyeing time is 30min. After that, the temperature was raised to 65°C at 2°C / min, and the NaHCO3 / Na2CO3 buffer solution was added twice, the pH was controlled at 8, and the color ...

Embodiment 2

[0053] A method for dyeing clothing with intelligent sweat acid-base discoloration, comprising the following steps:

[0054] 1) Pre-dyeing treatment: Before dyeing, after winding the cotton yarn according to the density of 0.33g / cm3, because the pressure between the yarns is tighter than that of the fabric, fully soak the yarn in dimethyl sulfoxide (DMSO) solution for one hour Two hours, during which ultrasonic vibrations are used to promote yarn expansion.

[0055] 2) Dyeing:

[0056] Dyeing formula: Benthic algae natural raw material concentrate is 2% relative to the weight of the fabric; NaHCO with pH=8 3 / Na 2 CO 3 buffer solution;

[0057] When dyeing, take 2% benthic algae natural raw material concentrate relative to the weight of the fabric, mix the soaking solution (DMSO) and water one to one as the dyeing solution, and the bath ratio is 1:30. Put the cheese dyeing machine at room temperature for dyeing, adjust the cheese dyeing machine to start dyeing from the po...

Embodiment 3

[0064] 1) Printing:

[0065] Dye formula: 2% benthic algae natural raw material concentrate relative to the weight of the fabric, 5% mordant, 4% urea, 2% ammonium sulfate, mix with water, stir to fully dissolve, then add paste (sodium alginate and synthetic dragon Glue 1:1 mixed with 40% solid content paste) and fully stirred in a beaker for two hours for later use.

[0066] Print the clothes, dry at 60°C for 10 minutes, and steam at 105°C for 15 minutes.

[0067] 2) Post-processing: ① Drain after dyeing → ② Rinse with cold water to remove undyed dye → ③ Soap (85℃×20min, soap flakes 2g / L) to remove floating color and increase gloss → ④ Wash with water → ⑤ Dry at 60℃ Dry.

[0068] The discoloration effect of the resulting printed clothes is shown in Table 3.

[0069] Table 3 The discoloration effect of the clothes printed with benthic algae natural dyes

Abstract

The invention discloses an intelligent sweat acid-base discoloration clothing, which belongs to the field of textile dyeing and finishing technology. The present invention provides a method for preparing yarns or fabrics with fast response to pH, specifically, soaking yarns or fabrics in dyes containing natural raw material concentrates, wherein the natural raw materials include benthic algae, alizarin red S , one or more of red bayberry. The intelligent sweat color-changing fabric prepared by the method of the present invention has obvious and reversible discoloration when the pH of the sweat changes. When it reaches a certain color, it will warn the wearer to keep the clothes clean in time, and the color change from sweating to fabric color does not exceed 80s. It can meet the rapidity, reversible pH discoloration and durability, and realize the intelligent real-time monitoring of the sweat volume of the clothes worn by the human body.

Description

technical field [0001] The invention belongs to the field of textile dyeing and finishing technology, and in particular relates to an intelligent sweat acid-base discoloration clothing. Background technique [0002] Color-changing textiles can change color according to external stimuli, such as temperature, light, electricity, etc., and then transmit external changes through visual signals, and play a role in warning, detection, and tracking. At present, the research on color-changing textiles is mainly focused on thermal and photochromic, but acid-base discoloration cannot be ignored. It can be used in many fields for pH monitoring. At the same time, textiles are light in weight, large in coverage, breathable, and Washable, strong and other advantages. Researchers have shown great interest in textiles dyed with natural dyes, and endowing fabrics with novel functions while dyeing with natural dyes has also attracted more and more attention from researchers. Among them, the...
