Problems solved by technology

At present, most antibacterial fabrics are obtained by coating antibacterial agents on fabrics by post-finishing padding or coating. This type of antibacterial fabrics has the problem of not being washable. With the increase in the number of washings, the antibacterial agents are completely peeled off. The antibacterial effect is also lost

Embodiment 1

[0017] Embodiment 1: 1.5D × 38mm cotton staple fiber

[0018] Raw material: PTT chip 1000kg, functional masterbatch 8kg

[0019] Dry the PTT slices and functional masterbatch separately. The dried PTT slices enter the dry slice silo, and the functional masterbatch is added to the color masterbatch injection device. After fully stirring before entering the screw extruder, enter the screw extruder for further processing. Melt spinning, UDY undrawn yarn is obtained by winding and falling barrel. After equilibrating for 24 hours in a balance room with a temperature of 22°C and a humidity of 65RH, post-spinning and drafting are carried out, and the drawn tow is dried at 85°C for 60 minutes, cut and packed to obtain a cotton-type antibacterial PTT short of 1.5D×38mm Silk. The nano-silver content in the PTT fiber is 50ppm.

[0020] After spinning and weaving, the fiber blended and pure spun fabrics are obtained, and their antibacterial effects are as follows:

[0021] 50% Antibac...

Embodiment 2

[0023] Example 2: 3D × 70-100mm ranging from long-haired staple fiber

[0024] Raw material: PTT chip 1000kg, functional masterbatch (nano-silver) 18kg

[0025] Dry the PTT slices and functional masterbatch separately, the dried PTT slices enter the dry slice silo, the functional masterbatch is added to the color masterbatch injection device, and after fully stirring before entering the screw extruder, enter the screw extruder for melting Spinning, UDY undrawn yarn is obtained by winding and falling barrel. After equilibrating for 24 hours in a balance room with a temperature of 22°C and a humidity of 65RH, post-spinning and drafting are carried out, and the drawn tow is dried at 85°C for 60 minutes, cut and packed to obtain 3D×70-100mm unequal length antibacterial PTT hairy staple fiber. The nano-silver content in the PTT fiber is 110ppm.

[0026] After spinning and weaving, the fiber blended and pure spun fabrics are obtained, and their antibacterial effects are as follow...

Embodiment 3

[0029] Example 3: 2D × 50-70mm ranging from long-haired staple fiber

[0030] Raw material: PTT chips 1000kg, functional masterbatch (nano silver) 5kg

[0031] Mix PTT slices and antibacterial functional masterbatch evenly, melt in the same spinning screw at 230-260°C, mix and stir well, and then spray the mixed spinning melt through the spinneret hole at 255-265°C , and was wound and collected at a speed of 1000m / min to obtain UDY tow, stored in a balance room with a temperature of 24°C and a humidity of 65RH for 24 hours, and then post-drawing, using a two-step drafting method in a cold water bath, cold water temperature 20-24°C, tension heat setting temperature is 110-120°C, post-spinning drying temperature is 80-85°C, time is 40-50min, the dried fibers are cut and packed to make 2D×50 -70mm long-haired antibacterial PTT wool-type staple fiber. The nano-silver content in the PTT fiber is 40ppm.

Abstract

The invention discloses a short and antibacterial polytrimethylene terephthalate fiber and production method thereof, which adds master batches with antibacterial functions and amounting for 0.2-2 percent in mass to fiber during the spinning fiber smelting. The invention mixes antibacterial silver nanoparticle master batches to PTT slice for mixed spinning. The produced short fiber can be spun purely or spun with other various long or short fibers into blended yarns. The finished yarn has an antibacterial rate above 95 percent and can effectively kill most harmful bacteria. The antibacterial effect can not be changed after even a plurality of washing and the invention is also provided with excellent performance of ordinary PTT fiber product and is ideal spinning material in fields such as medical treatment, sanitation and sports, etc.

Description

1. Technical field [0001] The invention discloses a short polytrimethylene terephthalate fiber and a production method thereof, and more particularly discloses an antibacterial polytrimethylene terephthalate short fiber and a production method thereof. 2. Background technology [0002] With the advancement of science and technology, while enjoying the pleasure brought by science and technology, people also suffer the consequences of civilization development. Environmental pollution makes us have nowhere to escape. While we are using high-tech methods to find complete cures for each disease, new and unknown diseases are emerging one after another, seriously threatening human health. Therefore, more and more people hope to find an umbrella to protect themselves from disease. Adding a fungicide with a bactericidal effect to clothing can achieve the purpose of killing most of the currently known pathogenic bacteria, and can properly remove body odor caused by sweating and other...
