Description

Fiber treatment agent and fiber treated with the fiber treatment agent

technical field

The present invention relates to a fiber treatment agent and fibers treated with the fiber treatment agent.

Background technique

In the past, products using fibers such as blouses, dress shirts, shorts, skirts, linings, and surface materials for seats of furniture and vehicles have flooded the market.

These fiber products require different characteristics of fiber materials according to their different uses. Such desired properties are, for example, moisture retention, water absorption, hygroscopicity, antistatic properties, and the like.

For example, as a blouse, because it is generally worn, it is often required to have hygroscopicity due to a lot of sweating. In order to satisfy this hygroscopicity, various fibers are used. Examples of such fibers include synthetic fibers such as nylon, polyester, acrylic, and polyurethane; natural fibers such as cotton, hemp, and wool; and composite fibers of the above.

In addition, attempts have also been made to treat these fibers with a specific fiber-treating agent to improve the above-mentioned properties, or to impart other special properties in addition to the above-mentioned properties.

For example, it is well known that, in addition to improving the above-mentioned characteristics, when the eggshell membrane is attached to the wound on the skin surface, it has the effect of healing the wound early, that is, it has wound healing properties. Therefore, in order to easily apply it on a large wound For upper application, the powder of eggshell membrane and fiber material are mixed together to make a thinner material, which is made into a sheet for healing wounds.

However, in order to make the wound-healing properties more effective in a sheet made of the fiber material having the aforementioned wound-healing properties, there has been a proposal (see JP-A-7-246234) of a production method in which eggshell membranes are used as soluble Prepare an aqueous solution, dip fabrics or non-woven fabrics into the aqueous solution, and dry them to form a sheet.

By this method, in the case of a one-time use such as a disposable, it is of course possible to exhibit characteristics such as wound healing properties without any problem.

However, in the technique described in the aforementioned gazette, a sheet such as a woven or non-woven fabric is immersed in an aqueous solution containing only eggshell membranes and dried, and thus the fixing force of the eggshell membranes to the sheet is weak. For this reason, when the sheet is repeatedly washed or used for a long time, the eggshell membrane will be removed, and the durability will decrease, and the moisture retention, water absorption, hygroscopicity, antistatic performance, and wound healing properties will not be maintained continuously. and other characteristics.

Evaluation Method 1

For the taffeta fabrics according to the first invention of Examples 1 and 2 and Comparative Examples 1 and 2, hygroscopicity, water absorption speed, and frictional electrification were measured. In addition, the water absorption rate and the frictional electrification voltage were measured for the taffeta fabrics according to the second invention of Example 3, Comparative Example 3, and Reference Example 1. In addition, the sample of the processed taffeta fabric was placed at 23° C. in an atmosphere with a relative humidity of 30% for 12 hours. After conditioning, the sample was placed at 30° C. and an atmosphere with a relative humidity of 80% to measure its weight change. This measures the aforementioned hygroscopicity. The aforementioned water absorption is measured according to the JIS L 1096-A method. The aforementioned friction zone voltage was measured according to the JIS L 1094-B method. The evaluation results are shown in Table 1.

Table 1 Hygroscopicity[%] Water absorption speed Friction band voltage [V] Example 1 2.1 1 second or less 200 Example 2 2.0 1 second or less 400 Comparative example 1 0.1 Does not absorb water for more than 5 minutes 4800 Comparative example 2 0.2 Does not absorb water for more than 5 minutes 4500 Example 3 - 1～5 seconds 1400 Comparative example 3 - Does not absorb water for more than 5 minutes 4200 Reference example 1 - 2 to 5 minutes 2800

From the evaluation results of this evaluation method 1, it can be seen that compared with Comparative Example 1, the hygroscopicity and water absorption speed of Example 1 are higher, and the frictional electrification voltage is lower, which is good in all aspects. Therefore, the fiber treated with the fiber treating agent (substance containing a reactive organic compound) of the present invention has improved water absorption, hygroscopicity, and antistatic performance.

Comparing Example 2 and Comparative Example 2, it can be seen that Example 2 has high hygroscopicity and water absorption speed, low frictional electrification voltage, and is good in all aspects. Therefore, the fiber treated with the fiber treating agent (substance containing a reactive organic compound) of the present invention maintains its effect even after washing, and thus has good durability.

In addition, in Comparative Example 2, in the initial state without washing, the hygroscopicity was 2.0%, the water absorption rate was 1 second or less, and the frictional electrification voltage was 500V. From the comparison between the initial state and after washing, it can be seen that when the fiber treatment agent contains only soluble eggshell membranes like the prior art, it has no durability.

In addition, comparing Example 3 and Comparative Example 3, it can be seen that Example 3 has higher water absorption speed and lower frictional voltage than Comparative Example 3, which is good in all aspects. In addition, when Example 3 was compared with Reference Example 1, the same results were obtained. Therefore, the fiber treated with the fiber treating agent (fiber treating agent containing an adhesive organic compound) of the present invention has improved water absorption and antistatic properties.

Evaluation method 2

A commercially available adhesive tape is pasted on the skin, after peeling off, after the skin glue is made rough with acetone/ether solution, the taffeta fabric cloth made by Examples and Comparative Examples is fixed on the upper arm, 6 hours a day, On fixed days, the conductivity of the upper arm wrapped with the cloth was measured. The evaluation results are shown in Table 2.

Table 2 0 days 1 day 3 days 7 days 14 days 21 days Conductivity [μS] Example 1 1.8 2.3 2.5 7.5 40.0 43.0 Comparative example 1 2.0 2.1 2.0 3.0 15.0 20.0

From the evaluation results of this evaluation method 2, it can be seen that Example 1 has higher conductivity than Comparative Example 1. The larger the value of the electric conductance, the higher the electric conductivity of the skin, regenerates the skin at the rough skin portion, and improves the moisturizing state of the skin.

Therefore, it can be seen that the fibers treated with the fiber treating agent (substance containing a reactive organic compound) of the present invention regenerate the roughened part of the skin, thereby improving wound healing and moisturizing properties. Furthermore, as in the test of this evaluation method 2, even if it is used for a long time, it is confirmed that there is a wound healing effect and a moisturizing effect, so that it can last for a long time and can maintain each characteristic.
