preparation example Construction
[0037] The antibacterial masterbatch mentioned in this embodiment is prepared by a preparation method of an antibacterial masterbatch in the present application, and the preparation method of the antibacterial masterbatch specifically includes the following steps:
[0038]Modification treatment: use silane coupling agent to modify nano-silica, filter and dry to obtain modified nano-silica;
[0039] Loading and coating: add dispersant in water, mix and stir modified nano-silica and nano-silver in water, filter and dry to obtain nano-silver carrier; then add dispersant and silane coupling agent, mix and stir nano-silver Carrier and PVC paste resin to obtain the coated nano-silver carrier;
[0040] Mixing extrusion: add silane coupling agent, mix and stir the coated nano-silver carrier and polyester resin, melt extrusion and granulate to obtain antibacterial masterbatch.
[0041] There is no particular limitation on the fiber-grade polyester chips mentioned in this embodiment, a...
preparation example 1
[0051] An antibacterial masterbatch, including the following components: 0.33kg of nano-silver, 0.85kg of nano-silica, 1.55kg of silane coupling agent, 4.2kg of dispersant, 83kg of polyester resin, and 10kg of PVC paste resin.
[0052] Among them, the silane coupling agent is KH-550;
[0053] The dispersant is sodium hexametaphosphate;
[0054] The preparation method of this antibacterial master batch comprises the following steps:
[0055] S1 modification treatment: Divide the silane coupling agent into three parts according to the mass ratio of 2:1:1, mix and stir nano-silica and 1 / 2 the amount of silane coupling agent, mix and stir for 30 minutes, then let it stand for 1 hour, keep The temperature is 40°C, modify the nano-silica, and then filter and dry the nano-silica, the drying temperature is 90°C, and the drying time is 40min, to obtain the modified nano-silica;
[0056] S2 load-bearing coating: add half of the amount of dispersant in water, and mix and stir the modif...

Abstract
The invention relates to the field of spinning, and particularly discloses an antibacterial master batch, a polyester DTY (Draw Textured Yarn) using the antibacterial master batch and a production method of the polyester DTY. The antibacterial master batch is prepared from the following components: nano silver, nano silicon dioxide, a silane coupling agent, a dispersing agent, polyester resin and PVC paste resin. The polyester DTY using the antibacterial master batch comprises the following components: the antibacterial master batch, a fiber-grade polyester chip, a color master batch, a bamboo fiber, an antistatic agent and other auxiliary agents. The nano-silver is used as an antibacterial active substance, and the nano-silica and the PVC paste resin are used for assisting the nano-silver to be dispersed in the polyester resin, so that the nano-silver dispersion uniformity in the antibacterial master batch is better, the nano-silver stability is better, and meanwhile, the compatibility of the antibacterial master batch with the fiber-grade polyester chips and the color master batch is better. Therefore, the dispersion uniformity of the nano-silver in the prepared terylene DTY yarn is good, and the terylene DTY yarn has a good antibacterial effect.
Description
technical field [0001] The application relates to the field of textile technology, more specifically, it relates to an antibacterial masterbatch, polyester DTY yarn using the antibacterial masterbatch and a production method thereof. Background technique [0002] Polyester DTY yarn is a type of textured yarn of polyester chemical fiber. In addition to the characteristics of general polyester such as wear resistance, heat resistance, corrosion resistance, easy washing and quick drying, it also has high bulkiness, good heat insulation, comfortable feel, Features such as soft luster. Polyester DTY yarn is widely used in clothing, bedding, decorative fabrics, national defense military supplies and other industrial fiber products. [0003] However, fiber products are prone to stains during use. These dirt not only affect the use of textiles, but also provide a good environment for microbial reproduction. Moreover, during the storage of fiber products, microorganisms are also pr...
