Problems solved by technology

[0004] The current antibacterial fiber can be modified by the original silk modification method, in which the original silk modification method will produce wool and broken ends, and can not get a fiber with a smooth handle
In addition, some antibacterial agents treat the fiber surface by impregnation, adsorption, etc., and the fibers may also fall off after repeated washing, and the antibacterial effect will be reduced.
Through the analysis of the existing technology, it is easy to find its shortcomings

Embodiment 1

[0022] Raw materials: 98 kg of polyester chips, 2 kg of nano-layered silver-based inorganic antibacterial agent.

[0023] Polyester chips are dried and pre-crystallized (drying temperature 170°C, drying time 3h, drying medium is hot air with a dew point of -70°C), blended with nano-layered silver-based inorganic antibacterial agents, and then melt-spun (spinning process parameters See Table 1), the first tanker oiling, clustering, two drafting, crimping (control the number of crimps is about 10%, and the curling rate is about 7%), the second spraying oiling (tanker oiling accounts for 80% %, spraying and oiling accounted for 20%, and the total oiling rate was 0.3%), cutting, relaxing heat setting, and packing.

[0024] The melt-spinning process flow adopted, and some of the spinning process parameters are shown in Table 1.

[0025] Table 1 The process parameters before spinning

[0026]

[0027] Combined oiling method is adopted to control the oiling rate.

Abstract

The invention relates to an antibacterial fine denier silicon polyester short fiber and process for preparation, wherein the fiber comprises nano layered Ag-type inorganic antibacterial agents and polyester chips, and the two are made through blending, melting and spinning. The process for preparation comprises that: (1) the polyester chips are dried in hot air at 160-180 DEG C under -70 DEG C ofdew point for 2-4 hours to do a pre-crystallizing. (2) The polyester chips and the nano layered Ag-type inorganic antibacterial agents are mixed and through melting, spinning, a first tanker oil, bunching, two working drafting, curling, a second tanker oil, cutting, a relaxation heat setting machine and packing. The invention is capable of using prior production facilities, the production is capable of being done through changing process parameters, products not only are capable of being used for related bed clothes such as a quilt cover, but also have wide using in health and medical fields.

Description

technical field [0001] The invention belongs to the field of fine-denier silicon-containing polyester staple fibers, in particular to antibacterial fine-denier silicon-containing polyester staple fibers and a preparation method thereof. Background technique [0002] With the continuous improvement of people's living standards, people's requirements for clothing are not only beautiful and durable, but more and more focus on comfort. Irregularization and functionalization are hot spots in the development of chemical fibers today. Clothes made of various differentiated fibers that have emerged in recent years are increasingly favored by consumers. The development of micro-denier silicone polyester staple fibers with antibacterial properties is just in line with the above-mentioned trends. [0003] The fine denier silicone polyester staple fiber has soft hand feeling, good bulkiness and strong warmth retention effect, and is a substitute for down products. It can be used in t...
