Problems solved by technology

However, the melting method or dry spinning method requires complicated equipment, large investment and high cost.
[0005] Most of the known composite fibers containing alginate components are co-spun with non-alginic acid polymers, but because sodium alginate is mixed with other polymer components, the physical and mechanical properties of the final finished fibers are poor. , the fiber strength and elongation are low, and its application is limited to some specific fields, which greatly limits the application range of this fiber

Abstract

The present invention discloses a kind of composite negative ion cellulose / alginate fiber and its preparation process. Technologically, the present invention features that viscous sodium alginate solution prepared in certain technological condition, functional finishing agent slurry of negative ion generating material and cellulose xanthate in certain weight proportion are mixed to form the spinning solution, and the through further spinning and refining steps, the composite negative ion cellulose / alginate fiber is prepared. The composite fiber consists of cellulose 76-99.6 weight portions, sodium alginate 0.02-15 weight portions and negative ion generating material 0.02-9 weight portions. The composite fiber may be used in weaving fabric with the functions of killing bacteria, protecting skin, promoting wound healing, generating negative ion, etc. and is suitable for use in medical field and in making various kinds of high grade underwear, etc.

Description

Technical field [0001] The invention relates to man-made cellulose fibers, in particular to a negative ion cellulose / alginate composite fiber, and also relates to a preparation method of the composite fiber. Background technique [0002] Air anion is a substance that is very beneficial to human health. Inhaling a certain concentration of anion air can regulate the function of the nervous system, promote blood circulation, improve myocardial function, enhance myocardial nutrition and cell metabolism, improve immunity and promote health. Negative ions can make people energetic, healthy and long-lived. In addition, they can also get rid of asthma, high blood pressure, neurasthenia, emphysema, coronary heart disease and other diseases. The main component of tourmaline is a silicate material with a ring structure of aluminum, sodium, iron, magnesium, and lithium characterized by boron. Tourmaline has pyroelectricity and piezoelectricity, and can effectively generate negative ions. [...
