Description

The present invention relates to a fiber treatment composition, a fiber processed product, and a method for producing a fiber processed product.

In recent years, in order to impart functionality such as moisture retention to fibers, various functional agents have been attached to the fiber surface or incorporated into the fiber. For example, Patent Document 1 proposes a rayon fiber containing Aphanothece sacrum-derived polysaccharides in a ratio of 0.01 to 0.5 parts by mass per 100 parts by mass of rayon in order to obtain a rayon fiber with excellent moisture absorption, water absorption, and quick-drying properties. It is reported that a rayon fiber with excellent moisture absorption, water absorption, and quick-drying properties can be obtained.

JP 2019-11542 A

However, Patent Document 1 describes dissolving polysaccharides derived from Aphanothece sacrum in a fiber raw material liquid for rayon and then spinning the material. Because the fiber treatment agent is also contained inside the fiber, there was a problem in maintaining the original properties of the fiber while also imparting new properties such as moisture absorption. In addition, it was difficult to mix polysaccharides derived from Aphanothece sacrum into the raw material liquid for various fibers other than rayon, animal fibers, and synthetic fibers, and there were problems in extending the use to fibers other than rayon.

The present invention has been made to solve the above problems, and aims to provide a fiber treatment composition containing sulfated polysaccharides, which can be used to obtain a fiber processed product that is excellent in water absorption, moisture retention, moisture absorption and release properties, and has a pleasant feel to the touch. Another aim is to provide a fiber treatment composition that can obtain a fiber processed product that has, in addition to the above properties, stain resistance and antistatic properties. Another aim is to provide a fiber processed product that has, in addition to the above properties, washing resistance that does not lose its functionality even after washing. Another aim is to provide a fiber processed product obtained using the fiber treatment composition, and a method for producing the fiber processed product.

"Sakuran"
An example of a sulfated polysaccharide derived from A. sacrum is "Sacrum (registered trademark)". Sacrum, which is one type of sulfated polysaccharide according to this embodiment, is a polysaccharide extracted from A. sacrum, which is a species endemic to Japan. Although Sacrum according to this embodiment is not limited to that derived from A. sacrum, it is preferable that it is a sulfated polysaccharide derived from A. sacrum.
SACRAN (registered trademark; hereinafter, the term "registered trademark" may be omitted) according to this embodiment is a polymer containing the same structural units as a polymer extracted from Aphanothece sacrum. For example, it may be a sulfated polysaccharide containing monosaccharides such as 6-deoxy sugar (and/or pentose), uronic acid, hexapyranose, and sulfated muramic acid as structural units. A preferred example of such a sacran is a sulfated polysaccharide extracted from Aphanothece sacrum (hereinafter, sometimes referred to as "sacran"). An example of a method for extracting sacran from Aphanothece sacrum is described in International Publication WO2008/062574.

For example, a specific method for extracting sacran from A. sacrum is to freeze and wash an appropriate amount of A. sacrum with water to remove water-soluble pigments, then remove fat-soluble pigments with an organic solvent such as ethanol, and dry the algae of A. sacrum. Then, 0.1N sodium hydroxide is added to the dried algae of A. sacrum, and the mixture is stirred at 60 to 80°C for 6 hours. The sugar derivative solution obtained by the above operation is neutralized, filtered, concentrated, and dried. In another example, sacran can be extracted from A. sacrum by heating an aqueous dispersion of A. sacrum in an autoclave at 135°C for 30 minutes. The extracted sacran may be purified by centrifugation, filtration, alcohol washing, etc. In addition, before extracting sacran from A. sacrum, A. sacrum may be frozen and then thawed, and then a process of removing pigments may be performed.
SACRAN according to this embodiment is a polysaccharide containing monosaccharides such as (A): 6-deoxy sugar (and/or pentose), (B): uronic acid, (C): uronic acid, (D): hexapyranose, and (F): sulfated muramic acid as structural units. An example of the state in which they are linked is shown in the following formula (1). Note that the arrangement of the structural units (monosaccharides) shown in formula (2) is only an example, and the arrangement of the structural units is not limited to the arrangement of general formula (2).

The ratio and average molecular weight of monosaccharides constituting SACRAN in this embodiment vary depending on the harvesting time and place of Aphanothece sacran. In one example of SACRAN, the ratio of sulfated muramic acid to the total structural units is in the range of 0.1 to 20 mol%, and the ratio of uronic acid to the total structural units is in the range of 1 to 50 mol%.
Moreover, the weight average molecular weight of an example of SACRAN is in the range of 1 million to 30 million.

A specific example of SACRAN in this embodiment is SACRAN manufactured by Green Science Materials Co., Ltd.

In this way, when the cationic resin contains the repeating unit (2), the affinity between the solvent of the pretreatment liquid and the cationic resin tends to be appropriately reduced. As a result, the stability of the pretreatment liquid as an emulsion can be improved.

By setting the content of the repeating unit (2) to 40% by mass or more and 90% by mass or less, the affinity between the solvent of the pretreatment liquid and the cationic resin tends to be appropriately reduced. As a result, the stability of the pretreatment liquid as an emulsion can be improved.

The temperature of the water vapor is within the range of 100 to 260°C, preferably 100 to 200°C, and more preferably 120 to 180°C. If the temperature of the water vapor is too low, the heat treatment may take a long time and may be insufficient.

If the material is deteriorated by the heat treatment, the material may be treated in multiple steps within a temperature range where the material is not deteriorated.
Any type of generator can be used as long as it can generate high-temperature steam. In addition to pressure cookers and autoclaves, superheated steam generators, superheated steam batch furnaces, nozzle-type steam sprayers, and the like can be used in this heat treatment process. In such cases, the base fabric may be treated by exposing it to high-temperature steam, or the surface of the base fabric may be treated in a pinpoint manner.

In addition, in order to promote adhesion of the fiber treatment agent of the present invention after the drying process and improve washability, the fiber may be heated in multiple steps within the temperature range. For example, the fiber may be treated twice at the same temperature within the above temperature range. One example is a method in which the fiber is treated at 120°C for 1 minute, and then treated at 150°C for 1 minute and 30 seconds. The first treatment may be performed at a temperature outside the above range, and the second and subsequent treatments may be performed at temperatures within the above range. One example is a method in which the fiber is treated at 70°C, and then treated with high-temperature steam such as steam at 160 to 180°C. The drying process in the present invention has the purpose of removing excess moisture and solvent, as well as the effect of promoting adhesion of the sulfated polysaccharide to the fiber and promoting film formation of the sulfated polysaccharide. Therefore, it is desirable to select the optimal drying process depending on the type of sulfated polysaccharide and the type of fiber substrate.

(2) Stain Resistance Based on JIS L-1919:2012, Test Method for Stain Resistance of Textile Products, Method A-2, powdered contaminants were prepared and a simple evaluation test for stains caused by fine powders such as dust and dirt was conducted. A test fabric sample of each textile product and the contaminant were placed in a polyethylene bag, and the inflated bag was rotated to determine the "resistance to staining" of the fabric, and the sample was washed to determine the "ease of removing stains."

<Powder-state pollutants>

<Resistance to dirt>
0.25 g of the powdery contaminant was placed in a polyethylene bag with a zipper (Unipack F-8, manufactured by Nippon Seisakusho Co., Ltd.), one test piece was then placed inside, and air was sealed in the bag using an air pump so that the bag was completely inflated. The pillow-shaped bag was then fixed to a rotating machine and rotated at a speed of 60±2 revolutions per minute for 60 minutes. Next, while changing the four corners of the test piece, the center of the back surface of the test piece was flicked five times with a finger to remove excess powder stain, and the degree of staining of the test cloth was evaluated. When flicking with a finger, two fingers were used, and the test piece was rotated 90 degrees after each flick, for a total of five flicks.

＜Easy to remove dirt＞
The washing operation was carried out with reference to the method specified in JIS L-0217, Appendix 1 [Test methods by symbol - Washing method (water washing)], No. 103 method. The detergent used in the washing operation was JAFET standard blend detergent available from the Japan Textile Evaluation Technology Council. After washing, rinsing, and spin-drying, the test pieces were hung to dry at room temperature. After drying, the degree of contamination of the test pieces was evaluated.

<Evaluation of stain resistance>
The color difference seen between the test piece before exposure to the contaminant and the test piece after contamination and washing/drying was judged using the staining gray scale specified in JIS L-0805. When the staining density was not uniform, the judgment was usually made on the average of the entire test piece. When the test piece was curled up and the staining density varied greatly depending on the part, the darker part was judged. When the staining density was darker in the wrinkled part of the test piece, that part was excluded from the judgment.
Based on the grade obtained from the staining gray scale, the stain resistance, which relates to the resistance to staining and the ease of removing stains, was evaluated into the following three stages (A, B, C ranks).

Stain resistance/resistance to dirt A (good): Grade 4 or higher on the gray scale B (fairly good): Grade 3 to 3-4 on the gray scale C (poor): Grade 2-3 or lower on the gray scale

Stain resistance/ease of removal of stains A (good): Gray scale value of grade 4 or higher B (fair): Gray scale value of grade 3 to 3-4 C (poor): Gray scale value of grade 2-3 or lower

(3) Electrostatic property (antistatic property)
According to JIS L-1094; Test method for electrostatic properties of woven and knitted fabrics, the textile products were subjected to the following methods A and B in an environment of temperature 20° C.±2° C. and relative humidity (40±2)%.

Method A Half-life measurement method; Evaluation of ease of dissipation of static electricity Using a half-life measurement device, a test piece of fabric (45 mm x 45 mm) was charged with an applied voltage of 10 KV, and the time (S) until the charged voltage decayed to half was measured as half-life.

Method B: Frictional electrification voltage measurement method; evaluation of resistance to static electricity accumulation Using a frictional electrification voltage measurement device, a test cloth piece (50 mm x 80 mm) was attached to a drum, which was rotated while being rubbed with a friction cloth (wool or cotton), and the electrification voltage (V)/frictional electrification voltage was measured 1 minute after the start of friction.

Based on the measurements obtained using Methods A and B, the electrostatic chargeability of the fibers was evaluated based on the criteria of half-life: 10 seconds or less, and frictional charging voltage: 2000 V or less, and textile products that met both numerical standards were deemed to have "good" antistatic properties (antistatic effect).

(Discussion)
As shown in Tables 5 and 6, the SACRAN (registered trademark) fiber processed products of Examples A3 to A7 obtained from the fiber processing composition containing the sulfated polysaccharide of the present invention were superior in moisture absorption and moisture release properties as well as in soil resistance and antistatic properties compared to the fiber processing composition H containing urea of Comparative Example A2 and the polyester base fabric only not containing the fiber processing agent of Comparative Example A3. In addition to the coating method of immersing the fiber processing composition in a solution state using a mangle coater, high functionality can also be imparted by a screen printing method using a stencil. When the fiber processed products of the present invention are used for, for example, 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 be soiled.
Furthermore, it is possible to provide a fiber treatment agent containing a polysaccharide as an ingredient, which has higher biodegradability and safety 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 bioirritation and is therefore safe, so that the fiber treatment agent of the present invention can be suitably used in fields where safety is important, such as clothing.

(Discussion)
As shown in Table 10 above, by carrying out the treatments of Examples B1 to B2 using the fiber treatment agent of the present invention or a fiber treatment agent containing the same, it is believed that the polyester fiber SAKRAN (registered trademark) fiber processed products are firmly fixed to the polyester fiber fabric base via the sulfate groups and carboxyl groups of the SAKRAN molecule of the sulfated polysaccharide and the cationic resin that constitutes the fiber treatment agent.

As shown in Table 10 above, the SACRAN® fiber processed products using polyester fiber as a base fabric in Examples B1-2, which are obtained by using a fiber pretreatment agent containing the cationic resin and binder of the present invention in advance and then a fiber treatment agent containing sulfated polysaccharides, are believed to be firmly fixed to the polyester fiber fabric base fabric via the sulfate groups and carboxyl groups of the SACRAN molecules of the sulfated polysaccharides on the surface of the fibers and the cationic resin and binder that make up the fiber pretreatment agent. This is because the surface of the polyester fiber is positively charged by the cationic resin contained in the fiber pretreatment agent, making it easier for the anionic sulfated polysaccharides that have sulfate groups and carboxyl groups to approach the surface of the fibers. It is also believed that the coexistence of a binder allows them to be firmly fixed to the surface of the fibers.

As shown in Table 12 above, in the SACRAN (registered trademark) fiber processed products having a base fabric of polyester fiber obtained by performing each of the treatments of Examples B3 to B7 using a fiber treatment agent containing the sulfated polysaccharide of the present invention, the sulfate groups and carboxyl groups of the SACRAN molecule of the sulfated polysaccharide are crosslinked with the functional groups of the crosslinking agent that constitutes the fiber treatment agent, and are further firmly fixed to the surface of the polyester fiber fabric of the base fabric via a binder.
Furthermore, as shown in Table 14 above, the sacran molecules of sulfated polysaccharides attached to the surface of the fibers can penetrate into the interior of the polyester fibers and be firmly fixed to the polyester fibers by subjecting them to the drying and heat treatment processes of Examples B8 to B11 of the present invention.
According to the present invention, the Sakuran fiber processed products shown in Examples B1 to B11 can be obtained as fibers in which the Sakuran molecules do not detach from the fibers but remain there even after repeated washing, and the functional properties such as moisture retention, moisture absorption and release, stain resistance, and antistatic properties are not reduced.

The viscosity of the dispersible fiber treatment agent of Example C1 after the dispersion step was measured using an E-type viscometer VISCOMETER TVE-25L (manufactured by Toki Sangyo Co., Ltd.)
