Description

  The present invention relates to a textile treatment agent containing amino-modified silicone and a method for suppressing yellowing of amino-modified silicone.

  Conventionally, it is known to use amino-modified silicone as a fiber conditioning agent in the textile industry. However, amino-modified silicones have a serious drawback in that amino groups are deteriorated by heat or ultraviolet rays due to aging and yellowing occurs. In order to prevent the above yellowing, a method of modifying an aminoalkyl group has been proposed. For example, Patent Document 1 discloses a reaction between an aminoalkyl group-containing organopolysiloxane and an epoxy compound, Patent Document 2 discloses a reaction with a higher fatty acid, and Patent Document 3 describes a modification of an aminoalkyl group by a reaction with a carbonate. The technology about is described.

It is also known to use an acid in combination when producing a silicone emulsion. For example, Patent Documents 4 to 6 disclose techniques related to a method for producing a microemulsion using amino-modified silicone. Patent Documents 7 to 8 disclose techniques related to a fiber treatment agent using amino-modified silicone.

  That is, in Patent Document 4, monovalent carboxylic acid (acetic acid, propionic acid, fatty acid) is used for the purpose of reducing the interfacial tension and promoting the decrease in particle size when producing a microemulsion containing linear polysiloxane. This technology is used together. Patent Document 5 is a technique of adding an acid (particularly an acid containing an amino group, such as glutamic acid or aspartic acid) as a neutralizing agent when producing a microemulsion composed of amino-modified silicone. Patent Document 6 is a technique that uses an acid (hypophosphorous acid, nitric acid, hydrochloric acid, lactic acid, glycolic acid, propionic acid, formic acid, acetic acid) as a neutralizing agent when producing a microemulsion containing amino-modified silicone. is there.

  Patent Document 7 discloses that when producing an emulsion-type fiber treatment agent having dilution stability, blending stability and mechanical stability, no oil spot formation, and good water repellency and flexibility. This is a technique in which an acid (a carboxylic acid such as formic acid, acetic acid, propionic acid, or butyric acid or an inorganic acid) is used in combination. Patent Document 8 describes a carboxylic acid (saturated aliphatic carboxylic acid) as a component that provides stability when producing a fiber treatment agent that does not cause yellowing problems and can impart good flexibility and smoothness. Acid, unsaturated aliphatic carboxylic acid, carbocyclic carboxylic acid, acid anhydride). In the example of Cited Document 8, a technique using acetic acid or phthalic acid in combination is disclosed, but both are formulated for the purpose of providing stability of the composition, and for the purpose of suppressing yellowing of amino-modified silicone.

Dye: Purple No. 201 Example 1
Using each component shown in Table 1, 150 g of the fiber product treating agent having the composition shown in Table 1 was prepared. At that time, a plastic plastic cup (capacity 200 mL) was used as a mixing container, and a magnetic stirrer was used as a mixing method. First, the component (e), the component (g), and water corresponding to 10% by mass of the entire fiber product treating agent were weighed and mixed in a container, and then the component (c) heated to the melting point or higher was added and further mixed. Next, a predetermined amount was added while mixing the component (a) at a rate of about 2 g / min, and mixed for about 30 minutes after completion of the addition. The remainder of the blended water was added to this and mixed, and component (d) was added. While continuing mixing, the component (b) and other components were added, and the pH was adjusted to a predetermined pH with the component (f) to obtain each fiber product treating agent. The yellowing inhibiting effect and texture of the obtained textile product treating agent were evaluated by the following methods. The results are shown in Table 1.

<Evaluation method of yellowing suppression effect>
15 g of each textile product treating agent blended by the above method is put in a glass screw tube (No. 6, 30 mm × 65 mm) having a capacity of 30 mL and sealed under atmospheric pressure (two each). This was stored in a thermostatic bath at 5 ° C. and 50 ° C. with the stoppers facing upwards and stored for 20 days, and then the cret value (420 nm absorbance × 1000) was measured with an absorptiometer. The difference in the cret value between the product stored at 5 ° C and the product stored at 50 ° C was determined. The Δklet value was calculated according to the following formula.

Δ kret value = (Kret value of product stored at 50 ° C.) − (Cret value of product stored at 5 ° C.)
<Texture evaluation method>
・ Pretreatment of textile products for evaluation New cut-and-sew (9 to 5 made by Chikuma Co., Ltd., beige, cotton / polyester = 50/50%) and new shirts (form-stabilized shirt (SSP), Flex Japan) BLUE RIVER, white, 100% cotton) is prepared, and 0.9 kg of underwear (100% cotton) and 0.6 kg of white shirt (white, cotton / polyester = 60/40%) are prepared as a weight adjustment cloth. In addition, a total of 1.8 kg of clothing was repeatedly washed 10 times with a two-basin washing machine (Toshiba Ginga VH-360S1) using a commercially available weak alkaline detergent (Kao Corp. Attack) (detergent concentration 0.0667 mass%) , Using 36 L of tap water (20 ° C.), washing 10 minutes—dehydration 3 minutes—rinsing 8 minutes (rinsing with running water, water volume 15 L / min.)). At the time when 5 minutes have passed since the rinsing of the last treatment time (the 10th time) has started, running water was stopped, and after draining, dewatering was performed for 3 minutes. Next, 36 L of tap water (20 ° C.) was injected, 23.33 g of each fiber product treating agent shown in Table 1 was added, and the mixture was stirred for 3 minutes. After the stirring was stopped, it was dehydrated for 3 minutes, and a cut-and-sew and a shape-stabilized shirt were taken out as evaluation clothes, each hung on a hanger in the shade, and hung and dried for 12 hours.

・ Texture evaluation After pre-treatment, after drying and drying for 12 hours, the fiber product that was left to stand in a constant temperature and humidity room at 25 ° C.-65 RH for 24 hours to be subjected to humidity conditioning treatment was used after the pre-treatment. As a contrast, a fiber product that was treated with tap water alone and similarly conditioned in a constant temperature and humidity room of 25 ° C.-65 RH was used as a control. The average score was obtained. The average score is greater than 1.0 and less than or equal to 2.0, ◎, greater than 0 and less than or equal to 1.0, ○, 0, Δ, −1.0 to less than 0 ×, −2.0 to less than −1.0 Judged as xx.

Both cut-and-sew and shape-stabilized shirts were evaluated against the control, but the trend was the same. Table 1 shows the results for the form-stabilized shirt.
・ Smoothness Contrast product is smoother: -2 points Contrast product is slightly smoother: -1 point Equivalent to control product: 0 points Slightly smoother than control product: +1 point Smoother than control product: +2 points
