Problems solved by technology

[0002] Firefighting clothing usually has high fire resistance. Because it is easy to sweat during fire rescue, it is common to wear sweat-absorbing cotton clothing inside the firefighting clothing. However, because cotton cloth absorbs sweat, it is easy to breed bacteria, and because cotton cloth has good hygroscopicity, It is easy to shrink and wrinkle after absorbing sweat, and it is easy to cause wrinkles of the fabric. In the prior art, the cotton cloth is usually directly dipped in a medium containing silver ions, so that the surface of the fabric is loaded with silver ions to achieve antibacterial properties. The content of active groups interacting with ions is less, which leads to a lower content of silver ions introduced into the surface of the fabric, which in turn results in lower antibacterial performance of the fabric. flammability, but the existing clothes directly achieve the flame retardant effect by padding the flame retardant, the flame retardant performance is low, and the clothes after the padding of the flame retardant are physically adsorbed between the flame retardant and the clothing, after many years After washing for the first time, the content of flame retardant decreases, which in turn reduces the flame retardant performance of the clothes.

Embodiment 1

[0031] The concrete preparation process of polyamino modifier is as follows:

[0032] Step 1: Take by weighing 0.91g thiosemicarbazide and add in 6mL ethanol solution and stir to dissolve, then add the dissolved thiosemicarbazide solution in an ice-water bath, then add 3.4g methyl acrylate dropwise to the reaction vessel, and control the rate of addition as 3ml / min, after the dropwise addition is complete, stir and react for 50min, then raise the temperature to normal temperature and stir for 2h, then carry out vacuum distillation to obtain product A, the reaction structure is as follows;

[0033]

[0034] Step 2: Add 10g of the product A prepared in step 1 and 90mL of ethanol to the reactor, and at the same time, add thiosemicarbazide to ethanol and stir to dissolve it into a thiosemicarbazide solution with a mass concentration of 60%, and then add it dropwise to the reactor 15g of the configured thiosemicarbazide solution, the rate of addition was controlled to be 3ml / min...

Abstract

The invention discloses an antibacterial crease-resistant fabric with flame retardation. The antibacterial crease-resistant fabric with flame retardation is characterized in that yarns are prepared from modified cotton fibers and flame-retardant fibers according to a mass ratio of 1:(0.82 to 0.84); then the prepared yarns are soaked for 1 to 1.5h in silver nitrate solution with mass concentrationof 200ppm; the obtained yarns are dried and spun; and then crease-resistant treatment is carried out on the obtained fabric to obtain the flame-retardant antibacterial crease-resistant fabric. In thefabric prepared by the invention, the nitrogen element and the phosphorus element are grafted onto the fibers by the chemical action, and after repeated washing, flame retardation cannot be changed, so that the flame retardation of the antibacterial crease-resistant fabric cannot be reduced due to repeated washing.
