Description
Technical Field
The invention belongs to the field of wet tissues, and particularly relates to a degradable disinfectant wet tissue.
Background
In daily life, in order to eliminate bacteria and viruses which may be contacted with a human body, people adopt a plurality of disinfection modes, and the wiping disinfection mode adopted in the plurality of disinfection modes is the most convenient, accurate and effective disinfection mode. Therefore, the disinfectant wet tissue becomes one of the necessary cleaning products. The effective disinfection mode aiming at the virus and bacteria is to adopt alcohol for disinfection, and the adoption of the alcohol for disinfecting the wet towel is the most convenient, fastest, most safe and effective mode.
However, most of the traditional wet tissues take non-woven fabrics made of polyethylene, polypropylene, polyester and polyamide as substrates, and although the cost is low, the most defects are that biodegradation cannot be carried out, recycling is difficult, and white pollution can be caused by using a large amount of the traditional wet tissues. In addition, in order to manufacture functional wet tissues, a solution containing a plurality of chemical components is required to be prepared, and a water source is easily polluted. With the enhancement of the environmental awareness of people, the biodegradable materials are used for manufacturing the environment-friendly wet tissues, which becomes a appeal for people, and more countries, companies and enterprises are vigorously developing various degradable textiles. In particular to degradable textile which can be suitable for being used as a disinfection wet tissue.
In view of the above, the present invention is particularly proposed.

The natural viscose fiber has the characteristics of comfort, good hand feeling, easy dyeing and the like of natural fiber cotton, and also has the environmental protection advantage which is not possessed by the traditional viscose fiber. The wood pulp fiber is one of the raw materials of wood pulp of trees. However, unlike the conventional plant fiber, it is a secondary fiber (i.e., a product separated from the original wood fiber, which is frequently used in spinning, such as Australian wood fiber underpants, SIMWOOD fiber socks, and towels made of wood fiber), and is named as wood pulp fiber since it is mainly extracted from wood pulp. Bamboo fiber is cellulose fiber extracted from naturally growing bamboo, and the fifth most natural fiber is cotton, hemp, wool and silk. The bamboo fiber has the characteristics of good air permeability, instant water absorption, strong wear resistance, good dyeing property and the like, and has the functions of natural antibiosis, bacteriostasis, mite removal, deodorization and ultraviolet resistance.

The sterilized wet tissues of examples 1 to 3 and examples 7 to 9 were treated by soil landfill and the degree of degradation thereof was measured, and the results are shown in Table 1.
TABLE 1
As can be seen from the results of the above table, the nonwoven sheet of the present invention made of lyocell fiber in an amount of 100% and the nonwoven sheet made of lyocell fiber, wood pulp fiber and bamboo fiber are naturally and rapidly degraded.
Experimental example 2
The sterilized wet tissues of examples 1 to 3 and examples 7 to 9 were measured for their antibacterial properties using the existing standards, and the results are shown in Table 2.
TABLE 2
Comparative example 1
In this comparative example, the influence of the water absorption of the spunlace nonwoven fabric prepared from the mass ratio of lyocell fibers, wood pulp fibers and bamboo fibers was examined. The process in this comparative example was conducted in accordance with the process of example 7, and the mass ratios of lyocell fiber, wood pulp fiber and bamboo fiber were varied, and the results are shown in Table 3 below.
TABLE 3
| Mass ratio of lyocell fiber, wood pulp fiber and bamboo fiber | Water absorption% |
| Example 1 | 904％ |
| 70：20：10 | 885％ |
| 75：10：15 | 923％ |
| 80：15：5 | 962％ |
| 80：10：10 | 941％ |
| 85：10：5 | 927％ |
| 90：5：5 | 928％ |
From the above results, it can be seen that when the mass ratio of the lyocell fibers, the wood pulp fibers and the bamboo fibers is 80: 15: when 5, the nonwoven fabric sheet has the best water-absorbing effect.
Comparative example 2
In this comparative example, the influence of the degree of fibrillation of lyocell fibers on the water absorption of the produced spunlace nonwoven fabric was examined. The process in this comparative example refers to the process of example 7, the mass ratio of lyocell fibers, wood pulp fibers and bamboo fibers being 80: 15: the lyocell fibers were fibrillated to different degrees, and the results are shown in table 4 below.
TABLE 4
| Index of fibrillation | Water absorption% |
| 1 | 885％ |
| 2 | 923％ |
| 3 | 962％ |
| 5 | 941％ |
| 6 | 927％ |
| 7 | 928％ |
As can be seen from table 4 above, the nonwoven sheet made of lyocell fiber, wood pulp fiber and bamboo fiber has the best water absorption effect when the fibrillation index of lyocell fiber is 3 to 5.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
