Problems solved by technology

Although the above patents all belong to the use of natural aluminosilicate as a deodorizing adsorbent to prepare cellulose fibers, if the traditional cellulose fiber production process is adopted, as known knowledge, the pulp is soaked in lye and yellowed with carbon disulfide and then added with lye The viscose spinning solution is made into viscose spinning liquid, which is formed by wet spinning and spinning process after degassing and aging. The antibacterial and deodorizing function of the fiber, the test shows that after dissolving and adding aluminosilicate powder with a content of 7% p-methyl fiber, mixing evenly, spinning and refining, the burning residue method is used to detect the aluminum in the final fiber The content of silicate is about 1.9%, and more than 5% of the effective substances of aluminosilicate are decomposed and lost by sodium hydroxide and sulfuric acid

Abstract

The invention provides an antibacterial and deodorization cellulosic fiber which comprises 1-10wt% of aluminosilicate sustained-release microcapsule and 1-5wt% of bamboo charcoal nano powder, wherein the dry breaking strength of the antibacterial and deodorization cellulosic fiber is 1.80-2.60cN / dtex and the wet breaking strength is 0.90-1.50cN / dtex. A preparation method of the antibacterial and deodorization cellulosic fiber comprises preparation of denatured viscose, spinning and after-treatment, wherein the aluminosilicate sustained-release microcapsule is added in the processes of spinning and after-treatment. The antibacterial and deodorization cellulosic fiber has the advantages that the taking performance is excellent, the spinning performance is good and the antibacterial and deodorization functions are prominent; the bamboo charcoal sizing agent is dissolved and then is added into aluminosilicate powder, and then the bamboo charcoal sizing agent and the aluminosilicate powder are uniformly stirred, so that the aluminosilicate powder is prepared into the aluminosilicate sustained-release microcapsule; the aluminosilicate sustained-release microcapsule is added before the spinning by using a pre-spinning injection manner; in the presence of the microcapsule, the active substance decomposition loss and structure damage caused by the direct contact of the strong acid-base and aluminosilicate are prevented; along with the acid bath forming or friction fracture, the active ingredients of the aluminosilicate microcapsule in the textile are slowly released; the nano charcoal powder adsorbs the peculiar smell, so that the long-term antibacterial and deodorization functions are realized.

Description

technical field [0001] The invention relates to the technical field of modified cellulose, in particular to an antibacterial and deodorizing cellulose fiber and a preparation method thereof. Background technique [0002] With the progress of society and the improvement of people's living standards, the concept of people's clothing is constantly updated, which puts forward higher requirements for the functionality of textiles and the comfort and beauty of products. However, the production of natural fibers such as cotton, hemp, silk, and wool is affected by the natural climate and the contradiction between grain and cotton, and the output growth is very slow, which is far from meeting the actual demand. [0003] Cellulose in nature is not only a large reserve, but also an inexhaustible renewable resource. Only a very small part of this raw material is currently made into fibers. With the continuous deepening of human understanding of nature, the utilization of cellulose wil...
