Abstract
The invention discloses a method for preparing a nanometer chitosan fiber containing antibacterial yarn, which comprises the following steps of: dissolving chitosan into a 0.1-3% chitosan solution with 0.2-4% acetic acid, lactic acid or phosphoric acid; then preparing nanometer chitosan fiber by using an electrostatic spinning method; and ensuring that cotton yarns or yarns of flax and ramie pass through an anode and a cathode of an electrostatic spinning device and accept the nanometer chitosan fiber to prepare a product. The nanometer chitosan fiber prepared through an electrostatic spinning technology has the characteristics of fine fiber, high porosity, high surface specific volume, and the like, therefore, the binding force of the nanometer chitosan fiber and the cotton yarns or yarns of flax and ramie is strong. The invention has the advantages of simple process and low cost.
Description
Technical field
The present invention relates to a kind of preparation method of antibiotic yarn.
Background technology
Along with improving constantly of progress, development of science and technology and the living standards of the people of society, people are more and more higher to the requirement of textiles, and the development of functional textile product has become the focus of textile industry, and wherein antibacterial fabric more is subjected to user's favor.Shitosan is the unique alkaline polysaccharide of occurring in nature, obtains application more and more widely in recent years at aspects such as chemical industry, environmental protection, food, medicine, cosmetics, agriculturals.Because chitin fiber has positive charge, when electronegative bacterium microbe contacted, the electric charge of bacterium surface was neutralized, thereby makes bacterium receive inhibition, loses activity, and reaches antibiotic purpose.
At present chitin fiber is by making chitin fiber with shitosan through wet method, dry method or dried wet method Direct Spinning, then with chitin fiber by with blending such as cotton, fiber crops, make the anti-bacterial fibre of chitosan-containing fiber, further be processed into various textiless again.But because the chitin fiber for preparing like this is thicker, fragility is big, easy fracture, and after particularly washing through the bubble of water, chitin fiber is easier to be lost, so the antibacterial textile effect descends significantly.
Summary of the invention
The object of the present invention is to provide a kind of preparation method who contains the antibiotic yarn of Nano chitosan fiber with durable antibacterial functions.
Technical solution of the present invention is:
A kind of preparation method who contains the antibiotic yarn of Nano chitosan fiber, it is characterized in that: comprise the following steps: shitosan is 0.1 ~ 3% chitosan solution with 0.2 ~ 4% acetic acid, lactic acid or phosphoric acid dissolving, adopt the Nano chitosan fiber of electrospinning process preparation then, with cotton yarn or the dimity between the anode of electrostatic spinning apparatus and the negative electrode by and accept the Nano chitosan fiber, promptly make product.
Technological parameter during electrostatic spinning is: voltage 15 ~ 30KV, solution flow rate is 0.2ml/h, and needle point and the distance of collecting between the screen are 5 ~ 15cm, and the point-to-point speed of cotton yarn or dimity collecting drum is 0.5 ~ 5m/ hour, rotating speed is 0 ~ 10 rev/min, and the weight percentage of shitosan is 0.5 ~ 5%.
The present invention has characteristics such as tiny, the highly porous property of fiber, high face specific volume by the Nano chitosan fiber of electrostatic spinning technique preparation, and is therefore strong with the adhesion of cotton yarn/dimity; Can be by change time and the rotation or non-rotating that the cotton yarn or the dimity stop between anode and negative electrode by regulating the content of shitosan in the blended fiber, the content of shitosan can be controlled at 0.1 ~ 5%; Technology of the present invention is simple, and cost is low.
The invention will be further described below in conjunction with embodiment.
The specific embodiment
A kind of preparation method who contains the antibiotic yarn of Nano chitosan fiber, comprise the following steps: shitosan with 0.2 ~ 4%(example 0.2%, 2%, 4%) acetic acid (or lactic acid or phosphoric acid) dissolving be 0.1 ~ 3%(example 0.1%, 1%, 3%) chitosan solution, adopt the Nano chitosan fiber of electrospinning process preparation then, with cotton yarn or the dimity between the anode of electrostatic spinning apparatus and the negative electrode by and accept Nano chitosan fiber (being about to the Nano chitosan fiber is directly injected on the cotton yarn or the dimity), promptly make product.
Technological parameter during electrostatic spinning is: voltage 15 ~ 30KV(example 15KV, 20KV, 30KV), solution flow rate is 0.2ml/h, needle point and the distance of collecting between the screen are 5 ~ 15cm(example 5cm, 10cm, 15cm), the point-to-point speed of cotton yarn or dimity collecting drum is 0.5 ~ 5m/ hour (example 0.5 m/ hour, 3 m/ hour, 5 m/ hour), rotating speed is 0 ~ 10 rev/min (0 rev/min, 5 rev/mins, 10 rev/mins of examples), and the weight percentage of shitosan is 0.5 ~ 5%(example 0.5%, 2%, 5%).
