Embodiment 1

[0023] White masterbatch formula: 39% of bottle-grade PET polyester chips with an intrinsic viscosity of 0.82dL / g, 1% of calcium stearate, 60% of Japanese Fuji titanium dioxide TA301, and 5% of silver zeolite antibacterial agent.

[0024] Preparation method: mix each component according to the mass ratio, then mix in a high-speed mixer, and then use a twin-screw extruder to melt and blend, granulate, dry, and pack to obtain the special color masterbatch for antibacterial health material fiber. Among them, the temperature conditions of twin-screw extruder melt blending are: 240°C in zone 1, 260°C in zone 2, 265°C in zone 3, 260°C in zone 4, 255°C in zone 5, 250°C in zone 6, 250°C in zone 7, Zone 8: 250°C, Zone 9: 240°C, Zone 10: 240°C, Head temperature: 260°C.

Embodiment 2

[0026] 39% of bottle-grade PET polyester chips with an intrinsic viscosity of 0.82dL / g, 1% of calcium stearate, 60% of Japanese Fuji titanium dioxide TA301, and 4% of silver zeolite antibacterial agent.

[0027] Preparation method: same as Example 1.

Embodiment 3

[0029] White masterbatch formula: 39% of bottle-grade PET polyester chips with an intrinsic viscosity of 0.82dL / g, 1% of calcium stearate, 60% of Japanese Fuji titanium dioxide TA301, 5% of silver zeolite antibacterial agent, and 1% of silane coupling agent .

[0030] Preparation method: same as Example 1.

Abstract

The invention relates to a special color master batch for antibacterial sanitary material fibers, and a preparation method thereof, and belongs to the field of sanitary material auxiliary materials. The special color master batch for antibacterial sanitary material fibers is prepared from, by mass, 30-50% of PET polyester chips, 0.5-3% of auxiliary agents, 30-70% of titanium dioxide and 4-6% of asilver ion antibacterial agent, wherein the polyester chips are bottle-grade chips with the intrinsic viscosity of 0.82 dL / g. The white master batch obtained by strictly controlling the temperature inthe preparation process can be widely applied to various sanitary material products, and has the characteristics of good dispersing performance, good filtering performance, long spinning period, highwhiteness, antibacterial performance and the like.

Description

technical field [0001] The invention belongs to the field of sanitary material auxiliary materials, and in particular relates to a special color masterbatch for antibacterial sanitary material fibers and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, the use of daily hygiene products such as wet wipes, masks, medical gloves and diapers continues to increase. At present, PE and PET skin-core composite yarns and PET non-woven fabrics have become the mainstream direction of the sanitary material market, and the consumption of white masterbatch for PET sanitary materials is also increasing year by year. In the field of sanitary materials, there are high requirements for the antibacterial performance of products, but the white masterbatch products currently on the market generally have poor antibacterial performance, and in the production process, due to poor dispersion, the replacement cycle of equipment components ...
