Description

  The present invention relates to a fiber treatment agent and a fiber material treatment method. More specifically, the present invention relates to a fiber treatment agent capable of imparting moisture retention and antifouling properties to a fiber material, and a fiber material treatment method including a step of attaching the fiber treatment agent to the fiber material.

  Conventionally, research on so-called functional processing has been carried out in which natural fibers, regenerated fibers, semi-synthetic fibers, synthetic fibers, or composite fiber materials thereof are imparted with properties that the fibers themselves do not have. Examples of such functional processing include flexible processing, hard finishing processing, shrink-proofing processing, flaw-proofing processing, flameproofing processing, waterproof and water-repellent processing, and the like. Furthermore, recently, specially functional processing that contributes to human health, such as deodorization processing, antibacterial processing, and moisturizing processing, has been studied, particularly in the field of textile materials that come into direct contact with the human body such as clothing and bedding. Or have been implemented.

  However, in spite of such processing aimed at contributing to human health, chemical products are generally used for the fiber treatment agent itself, so the safety of the fiber treatment agent to the human body from consumers. There is a doubt about natural products, and natural product orientation is increasing. Furthermore, the recent interest in ecology has demanded a textile treatment agent that is friendly to the global environment.

On the other hand, research on various effects and functions of the components collected from various plants is underway. For example, a treatment agent for fibers containing a plant collection material such as cucumber, carrot and tomato and a natural oil-soluble material such as olive oil, rice germ oil and almond oil has been proposed (see Patent Document 1). However, there are still few examples.

In addition, the effect of moisture retention and antifouling property by the fiber treating agent of the present invention was evaluated as follows.
(1) Moisturizing test Untreated cloth (fabric to which no fiber treating agent is applied) and treated cloth (12 cm × 25 cm) were placed in an oven dryer at 105 ° C. for 3 hours and then dried completely, and then untreated cloth And the mass of the treated cloth was precisely weighed with a chemical balance. The mass of the untreated cloth at this time is W ₀ (g), and the mass of the treated cloth is W ₁ (g).

Next, the completely dried untreated cloth and treated cloth are placed in an atmosphere adjusted to 20 ° C. and 78% RH, humidity is adjusted for 18 hours, and the mass of the conditioned untreated cloth and treated cloth is put on an analytical balance. And weighed precisely. The mass of the untreated cloth at this time is W _x (g), and the mass of the treated cloth is W _y (g). The moisturizing rate at this time was a value of 0 minutes.

Further, after that, the conditioned treated cloth was placed in an atmosphere adjusted to 20 ° C. and 40% RH, and the mass at every 30 minutes, 60 minutes, and 120 minutes was precisely weighed with an analytical balance. The mass at this time is also W _y (g). The moisture retention rate for each time of each treated cloth was calculated by the following calculation formula.
That is, the moisturizing rate is shown as a relative value based on the untreated cloth immediately after humidity control.
Moisturizing rate (%) = {(W _y −W ₁ ) / (W _x −W ₀ )} × 100

(2) Antifouling property test 0.1 mL of corn oil or soybean oil was dropped on untreated cloth and treated cloth, heat-treated at 120 ° C for 1 minute, and then washed at 40 ° C for 30 minutes. The washing bath was an aqueous solution containing 0.5% by mass of tridecanol ethylene oxide 5 mol adduct and 0.001% by mass of lipolase 100T (manufactured by Novo Nordisk), and the bath ratio was 1:30. . After washing, it was washed with overflow water for 2 minutes and dried at 80 ° C. for 15 minutes.

Next, the obtained untreated cloth and treated cloth were heated at a heating rate of 2 ° C./min in a dyeing bath containing 1% owf of Kayanol Milling Brown4GW and a bath ratio of 1:20. In the case of a polyester knit raw machine, the dyeing temperature was 100 ° C., and in the case of a cotton knitted raw machine, dyeing was performed at a dyeing temperature of 50 ° C. for 10 minutes, followed by light washing and drying.

  The dyed state of the obtained dyed fabric was visually evaluated in 10 stages. The case where the oil spot portion and other portions are stained equally is “10”, and the case where the oil spot portion is not stained at all is “1”. That is, the larger the evaluation value, the more oil is removed and the better the antifouling property.

Example 1
A 50 g (v / v) ethanol aqueous solution was immersed in 50 g of Akanekon strips and extracted for 24 hours at room temperature to obtain an extract. A 1% by mass solution of a non-volatile content of the extract (a 10% (v / v) 1,3-butylene glycol aqueous solution was used as a solvent) was prepared and used as a fiber treating agent.

  The non-volatile content of the extract was calculated from the residual mass ratio after taking 5 g of a sample in a petri dish and leaving it in a dryer at 105 ° C. (Perfect Oven PV-210, manufactured by Tabai Espec Co., Ltd.) for 3 hours. .

Examples 2-5
A fiber treating agent was obtained in the same manner as in Example 1 for each of the strips of Onji, Senna, Habusaw or Betel wax.

Test example 1
Nylon knitted fabric was treated by a continuous padding method using a treatment liquid in which 90 parts by mass of water was added to 10 parts by mass of the fiber treating agent obtained in the examples to make the total amount 100 parts by mass. The pickup was 50%. Subsequently, it was dried at 100 ° C. for 3 minutes and further heat-treated at 150 ° C. for 1 minute. This treated cloth was subjected to a moisture retention test.

Test example 2
The polyester / spandex knitted fabric was treated by a continuous padding method using a treatment liquid in which 90 parts by mass of water was added to 10 parts by mass of the fiber treating agent obtained in the examples to make the total amount 100 parts by mass. The pickup was 55%. Subsequently, it dried at 100 degreeC for 3 minute (s), and also heat-processed for 1 minute at 170 degreeC. This treated cloth was subjected to a moisture retention test.
The evaluation results of Test Examples 1 and 2 are shown in Table 1.

  As is clear from the above results, the fiber material treated with the fiber treating agent containing various extracts exhibits better moisture retention.

Test example 3
A polyester knit raw machine or cotton knitted raw machine was processed by a continuous padding method using a treatment liquid in which 90 parts by weight of water was added to 10 parts by weight of the fiber treatment agent obtained in the examples to make the total amount 100 parts by weight. The pickup was 60%. Subsequently, it dried at 100 degreeC for 3 minute (s), and also heat-processed at 170 degreeC for 1 minute (s). This treated cloth was subjected to an antifouling test. The evaluation results are shown in Table 2.

  As is clear from the above results, in the fiber material treated with the fiber treating agent containing various extracts, the attached oil stain is more easily removed by the lipase-containing detergent than the untreated cloth. I understand that.

  The fiber treating agent of the present invention can impart moisture retention and antifouling properties to the fiber material. Since the moisture retention property of the fiber material leads to the moisture retention effect of the skin, and therefore it is expected to prevent rough skin and reduce allergies, the fiber treatment agent of the present invention is a fiber material used for the part that directly contacts the skin, especially clothing. Is particularly useful. In addition, in the fiber material treated with the fiber treating agent containing the extract of the present invention, the adhered oil stains are easily removed by the lipase-containing detergent.
