(Evaluation of textile processed products)
Regarding the processed Sacran (registered trademark) fiber product C of Example 3, its hygroscopicity, moisture releasing property, and stain resistance were evaluated by the following methods, and the results are shown in Table 5. Further, Examples 4 to 7 and Comparative Examples 2 to 4 were also evaluated in the same manner as in Example 3, and the results are shown in Table 5.
Furthermore, the sacran fiber processed product C of Example 3 was evaluated for charging property (antistatic property) by the following method, and the results are shown in Table 6. Further, Comparative Example 3 was also evaluated in the same manner as in Example 3, and the results are shown in Table 6.

(1) Hygroscopicity and desorption properties According to the JIS L-1954:2022 test method for moisture absorption and desorption properties of fabrics over time, the moisture absorption process was carried out by moving the textile product from a low humidity side to a high humidity side, and from a high humidity side to a low humidity side. The mass change of the fiber processed product during the moisture release process when it was moved to the side was measured over time, and the moisture absorption rate, moisture release rate, and moisture absorption rate and moisture release rate of the test fabric were calculated. Hygroscopicity and moisture release properties were evaluated in the following three grades (ABC rank).

Hygroscopicity A: Moisture absorption rate is 0.60% or more or moisture absorption rate is 0.10%/min or more
B: Moisture absorption rate is 0.36-0.59% or moisture absorption rate is 0.06-0.09%/min C: Moisture absorption rate is 0.35% or less or moisture absorption rate is 0.05%/min or less Moisture release property A: Moisture release rate is 0.60% or more or moisture release rate is 0.10%/min or more B: Moisture release rate is 0.36 to 0.59% or moisture release rate is 0.06 to 0.09% /min C: Moisture release rate is 0.35% or less or moisture release rate is 0.05%/min or less

A simple stain evaluation test was conducted. A test cloth sample of each fiber processed product and a contaminant were placed in a polyethylene bag, and the inflated bag was rotated to determine how easily the fabric was stained and how easily the stains were removed by washing the sample. was determined.

<Powdered pollutants>

<Difficult to get dirty>
After putting 0.25 g of powdered contaminants into a polyethylene bag with a zipper (manufactured by Seisaku Nihonsha Co., Ltd., Unipack F-8), add one test piece and use an air pump to completely inflate the bag. A pillow-shaped bag filled with air was fixed to a rotating machine and rotated for 60 minutes at a speed of 60±2 rotations per minute. Next, while holding the four corners of the test piece, the central part of the back surface of the test piece was flicked with a finger five times to remove excess powder dirt, and then the degree of dirt on the test cloth was determined. When flicking with fingers, it was done with two fingers, and the test piece was rotated 90 degrees after each flick, making a total of 5 flicks.

<Easy to remove dirt>
The washing operation was carried out with reference to the method specified in Method No. 103 of JIS L-0217 Appendix 1 [Test methods by symbol - Washing method (washing with water)]. In the washing operation, JAFET standard combination detergent available from the Fiber Evaluation Technology Council was used as a detergent. After washing, rinsing, and dehydration, the specimens were hung to dry at room temperature. After drying, the degree of contamination of the test piece was determined.

<Determination of antifouling property>
The color difference between the test piece before exposure to the contaminant and the test piece after contamination and after washing/drying was determined using the gray scale for contamination specified in JIS L-0805. In addition, when the density of stain is not uniform, the judgment is usually made based on the average of the entire test piece. If the test piece was curled up and the stain density varied greatly depending on the area, the dark area was judged. If the stain in the wrinkled area of the test piece became darker, that area was excluded from the evaluation.
Based on the grade value obtained from the stain gray scale, the stain resistance in terms of stain resistance and ease of removing stains was evaluated in the following three grades (ABC rank).

Stain resistance/stain resistance A (good): Grade 4 or higher in gray scale value B (slightly good); Grade 3 to 3-4 in gray scale value C (poor): Grade 2-3 or lower in gray scale value

Stain resistance/ease of removing dirt A (good): Grade 4 or higher in gray scale value B (fairly good); Grade 3 to 3-4 in gray scale value C (poor): 2-2 in gray scale value Grade 3 or below

(3) Electrostatic properties (antistatic properties)
In accordance with JIS L-1094; Electrostatic test method for woven and knitted fabrics, the following methods A and B were carried out on processed fiber products at a temperature of 20°C ± 2°C and a relative humidity of (40 ± 2)%.

Method A Half-life measurement method; evaluation of the ease with which static electricity escapes Using a half-life measurement device, a test cloth piece (45 mm x 45 mm) is charged with an applied voltage of 10 KV, and then this charged voltage is attenuated to 1/2. The time (S)/half-life was measured.

Method B: Frictional charge voltage measurement method; evaluation of resistance to static electricity accumulation Using a frictional charge voltage measuring device, rub a piece of friction cloth (wool or cotton) while rotating a drum to which a test cloth piece (50 mm x 80 mm) is attached. One minute after the start of friction, the charging voltage (V)/friction charging voltage was measured.

Based on the measured values obtained by Method A and Method B, the chargeability of the fibers is evaluated based on half-life: 10 seconds or less and frictional charging voltage: 2000V or less, and textile processed products that meet both numerical standards are charged. The antistatic property (antistatic effect) was rated as "good."

(Consideration)
As shown in Tables 5 and 6, the Sacran (registered trademark) fiber products of Examples 3 to 7 obtained from the fiber treatment compositions containing the sulfated polysaccharide of the present invention were treated with urea of Comparative Example 2. In contrast to the fiber treatment composition F containing fiber treatment agent composition F and the polyester of Comparative Example 3, which is only a base fabric and does not contain a fiber treatment agent, it was excellent not only in hygroscopicity and moisture release properties but also in stain resistance and antistatic properties. In addition to the coating method of dipping the fiber treatment agent composition in a solution state using a mangle coating machine, high functionality can also be imparted by screen printing using a stencil. When the processed fiber product of the present invention is used, for example, in clothing, it is thought that the amount of water vapor in the clothing is controlled to reduce stuffiness, and the surface of the clothing is also less likely to get dirty.
Furthermore, it is possible to provide a fiber treatment agent containing a polysaccharide that is more biodegradable and safer than synthetic polymer-based functional fiber treatment agents. The sulfated polysaccharide used in the present invention not only has excellent functionality but also has low bioirritant properties and is safe. It can be suitably used in fields where safety is important.

The processed fiber product of this embodiment has excellent water absorption, moisture retention, hygroscopicity, and moisture release properties, and is a processed fiber product that is comfortable to the touch, and also has excellent stain resistance and antistatic properties. For example, it is expected to be used in a variety of applications, including clothing such as gloves, underwear, socks, shirts, and clothes, face masks, surgical masks, materials for disposable diapers, and cosmetic sheets such as wipe-off lotion sheets.
