Embodiment 1

[0023] This example provides the preparation of a cellulose fiber having the functions of anti-mite, anti-mildew and anti-bacteria with a specification of 1.11dtex*32mm.

[0024] Step 1. Preparation of Semen Cassiae-Houttuynia Alcohol Extract Microcapsules

[0025] The cassia seeds and Houttuynia cordata are pulverized to obtain a mixed powder of the cassia seeds and Houttuynia cordata, the particle diameter of the mixed powder body is 120 mesh, and it is set aside. Put the crushed cassia seed and Houttuynia cordata powder in a high-pressure tank, add it into the ethanol solution with a concentration of 60% at a bath ratio of 30:1, keep the temperature stable at 10°C, and stir under the pressure of 0.4MPa After grinding for 120 minutes, filter the treated feed liquid to obtain the filtrate and feed residue respectively, discard the feed residue, then heat and concentrate the filtrate to remove excess water and ethanol, and obtain the extract mainly containing Semen Cassiae and...

Embodiment 2

[0034] This example provides the preparation of a cellulose fiber with a size of 1.56dtex*38mm, which has anti-mite, anti-mildew and anti-bacterial functions.

[0035] Step 1. Preparation of Semen Cassiae-Houttuynia Alcohol Extract Microcapsules

[0036] The cassia seeds and Houttuynia cordata were pulverized to obtain a mixed powder of the cassia seeds and Houttuynia cordata, the particle size of the mixed powder was 98 mesh, and it was set aside. Put the crushed cassia seed and Houttuynia cordata powder in a high-pressure tank, add it into the ethanol solution with a concentration of 69% at a bath ratio of 25:1, keep the temperature stable at 12°C, and stir under the action of a pressure of 0.5MPa After grinding for 107 minutes, the processed feed liquid was filtered to obtain the filtrate and feed residue respectively, and the feed residue was discarded, and then the filtrate was heated and concentrated to remove excess water and ethanol to obtain the extract mainly contain...

Embodiment 3

[0045] This example provides the preparation of a cellulose fiber with a size of 1.56dtex*38mm, which has anti-mite, anti-mildew and anti-bacterial functions.

[0046] Step 1. Preparation of Semen Cassiae-Houttuynia Alcohol Extract Microcapsules

[0047] The cassia seeds and Houttuynia cordata were pulverized to obtain a mixed powder of the cassia seeds and Houttuynia cordata, the particle size of the mixed powder was 75 meshes, and it was set aside. Put the crushed Semen Cassiae and Houttuynia cordata powder in a high-pressure tank, add it into the ethanol solution with a concentration of 76% at a bath ratio of 20:1, keep the temperature stable at 15°C, and stir under the pressure of 0.6MPa After grinding for 88 minutes, the processed feed liquid was filtered to obtain the filtrate and feed residue respectively, and the feed residue was discarded, and then the filtrate was heated and concentrated to remove excess water and ethanol to obtain the extract mainly containing Semen...

Abstract

The invention belongs to the technical field of functional cellulosic fiber, and in particular relates to a cellulosic fiber with antibacterial anti-mold anti-mite functions and a preparation method of the cellulosic fiber. The cellulosic fiber comprises cassia seeds, houttuynia cordata, picrasma quassioides and a cellulosic fiber body. The invention further provides the preparation method of the cellulosic fiber. The invention further provides application of the cellulosic fiber or a product prepared by using the preparation method in fields of miteprevention, mold prevention and bacterium prevention. Experimental tests show that the inhibition rate of the cellulosic fiber provided by the invention for mites can be greater than or equal to 80% when compared with that of conventional adhesive fiber, the anti-mold grade of the cellulosic fiber can be greater than the level 2 provided by the GB / T 24346-2009 Textiles Evaluation On Anti-Mold Activity, the inhibition rate of the cellulosic fiber for staphylococcus aureus is greater than or equal to 90.2%, the inhibition rate of the cellulosic fiber for escherichia coli is greater than or equal to 91.8%, and the inhibition rate of the cellulosic fiber for candida albicans is greater than or equal to 89.6%. By adopting the cellulosic fiber, the technical defects that in the prior art cellulosic fiber is single in function and poor in anti-mite or anti-mold effect are solved.

Description

technical field [0001] The invention belongs to the technical field of functional cellulose fibers, and in particular relates to a cellulose fiber with antibacterial, anti-mildew and anti-mite functions and a preparation method thereof. Background technique [0002] Viscose fiber products have the characteristics of moisture absorption, good air permeability and comfortable wearing, and have been widely used. However, most viscose fibers in my country are ordinary varieties. With the improvement of people's living standards and the continuous enhancement of health and environmental protection awareness, ordinary varieties can no longer meet the needs of market and enterprise development, and vigorously promote the development of healthy, environmentally friendly products and green functionality. Fiber has become an irresistible trend. [0003] Mites belong to a class of tiny animals belonging to Arthropoda Arachnida. The body size is generally about 0.5 mm. The harm to the h...
