Problems solved by technology

[0002] Polyester-cotton blended fabrics are composed of two fibers with different properties. The dyeing and finishing process needs to take into account the fibers of two different properties. The traditional processing flow is to pre-treat the cotton according to the pre-treatment process, then dyeing and washing reduction washing, and then dyed cotton soaping , the whole process takes more than 12 hours, the energy and water consumption is large, the production cost is high, and a large amount of waste water containing high pollutants is discharged at the same time

Embodiment 1

[0035] The preparation method of antibacterial finishing agent is:

[0036] Nano-titanium dioxide powder was pre-dried in a vacuum oven at 80°C for 4 hours, weighed 20 parts into a jar filled with 150mL of absolute ethanol and 50mL of water, ultrasonically dispersed for 30min, then transferred to a three-necked flask, and put Stir in a constant temperature water bath at a constant speed, adjust the pH value to 6.5 with HCl, add 5 parts of coupling agent KH-570 and 12 mL of anhydrous ethanol mixture from the bottle mouth through a dropper after the stirring is stable, take it out after 2 hours of reaction, filter and wash, The obtained solid was Soxhlet extracted with absolute ethanol for 24 hours, and then dried in a vacuum oven at 80°C for 12 hours to obtain surface-modified nano-titanium dioxide;

[0037] Add 214 parts of water and 13 parts of cationic surface-modified nano-titanium dioxide into the reaction kettle, stir to dissolve and disperse for 30 minutes, raise the tem...

Embodiment 2

[0042] Short-process dyeing and finishing process of polyester-nylon-viscose blended fabrics, the technological process is one-bath pretreatment→polyester-nylon-viscose dyeing in the same bath→soaping→functional finishing;

[0043] 1) One-bath pretreatment:

[0044] According to the bath ratio of 1:10, put gray cloth and clear water in the machine tank; add alkali-resistant high-efficiency scouring agent XY-1 2g / L, oxygen bleaching stabilizer CN-215 2g / L, hydrogen peroxide 3g / L, chelating dispersant DR-520 2g / L, sodium hydroxide 3g / L; heat up to 98°C at a rate of 2°C / min, keep warm for 30min; cool down to 50°C, discharge waste liquid, and wash with water;

[0045] 2) Dyeing of polyamide and viscose in the same bath:

[0046] According to the bath ratio of 1:10, put the pre-treated polyester cotton cloth and clear water in the machine tank; add disperse dyes, neutral color-fixing reactive dyes, neutral dyes, sodium chloride 20-40g / L, leveling agent 1 -3g / L; heat up to 120°C a...

Abstract

The invention discloses a short dyeing and finishing process for polyester and viscose blended fabric. The short dyeing and finishing process for the polyester and viscose blended fabric includes thesteps of one-bath pretreatment, one-bath dyeing of polyester and viscose, soaping and functional finishing, wherein the one-bath pretreatment includes the steps of putting gray cloth and water in a cylinder according to the bath ratio of 1: 10, raising the temperature to 98 DEG C at a rate of 2 DEG C per minute, keeping the temperature for 30 minutes, cooling down to 50 DEG C, discharging waste liquid and washing with clear water; the one-bath dyeing of the polyester and viscose includes the steps of placing the pre-treated polyester-cotton cloth and clear water in the cylinder according to the bath ratio of 1: 10, adding dye auxiliaries, raising the temperature to 120 DEG C at a rate of 2 DEG C per minute, keeping the temperature for 40 minutes, cooling down to 60 DEG C, discharging wasteliquid and washing with clear water; the soaping includes the steps of washing with soap lotion whose mass concentration is 2 grams per litre, the bath ratio of 1: 10, and the temperature of 90 DEG Cfor 10 minutes; the functional finishing includes the steps of preparing finishing fluid, completely immersing the polyester and viscose blended fabric in the above-mentioned finishing liquid, conducting two dipping and two rolling with 85%-100% of mangle expression and drying at the temperature of 180 DEG C.
