Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a resin emulsion migration inhibitor.

Currently, resin emulsions are processed into textile products such as woven fabrics and non-woven fabrics, and are used in many applications such as resin processing, leather, and binders. Methods for using resin emulsions include dipping, spraying, and conniting. The migration inhibitor of the present invention prevents the resin emulsion particles generated during drying from migrating to the extreme parts of the textile product (for example, areas that dry quickly such as the surface) in a processing method in which the textile product is wetted with a resin emulsion and then dried. In the method of impregnating fibers with a resin emulsion and drying them, the migration of the resin is particularly noticeable in the case of thick textile products, and the resin is concentrated near the surface of the textile product. However, there are disadvantages such as the texture is hard and the drapability is lost.
"there were.

The inventors of the present invention conducted various studies in order to eliminate such drawbacks, and as a result, the general formula: ;50-700,X
, Yl or R-Co, R; hydrocarbon group having 7 to 22 carbon atoms] When processing a textile product with a resin emulsion by adding a compound having the following, the resin adheres uniformly to the inside of the textile product. In addition, it was discovered that the hand and drape properties were also improved, leading to the present invention. The water-soluble compound represented by the general formula is already known as a printing paste for conventional dye and pigment printing and as a thickener for printing paste. It is about 10%, but for dyes, pigments, etc., it is very high at 30-800%.

In the present invention, since it is necessary to uniformly adhere the resin emulsion to the textile product, the viscosity of the treatment liquid must not be made high like that of printing paste, and the viscosity is used within a range that keeps the viscosity low. To specifically explain the compound of the general formula, it is a polyalkylene glycol consisting of ethylene oxide alone, propylene oxide mainly composed of ethylene oxide, and a copolymer of butylene oxide, and a carbon number 7.

Examples include compounds such as nonylphenol stearyl ether ester of O).

As the resin emulsion, a polymerized resin emulsion of acrylic acid (ester), methacrylic acid (ester), vinyl acetate, etc., or a urethane emulsion obtained from an active hydrogen compound and polyisocyanate, etc. are used.

An example of a urethane emulsion is Sunbren UX-
2000 (f, riether type urethane emulsion, solid content 35%, manufactured by Sanyo Chemical Industries, Ltd.), Sunburen UX-2
700 (polyester type urethane emulsion, solid content 50%, manufactured by Sanyo Chemical Industries, Ltd., Sunbren UX-35
00 (polyether type urethane emulsion, solid content 4
0%, manufactured by Sanyo Chemical Industries, Ltd.).

The amount of the compound represented by the general formula in the present invention is 1 to 0.000%, preferably 0.8 to 0.00000%, more preferably 0.95 to 0.00000.000% in the resin emulsion treatment bath.
0. It is Ol. It is 0.01 to 20% with respect to the resin content, preferably 0.05 to 15%, and more preferably 01 to 10%. If it is added in excess of 1% to the treatment bath, the viscosity of the treatment bath increases, resulting in the disadvantage that the resin emulsion does not impregnate the textile product.The viscosity of the treatment bath is usually LOOOcp.
s or less, preferably 500 cps or less, more preferably 100 cps or less.

The method of adding the compound of the present invention is not particularly limited, and may be a method in which the compound of the present invention is first added to a resin emulsion and diluted with water, or a method in which the compound of the present invention is diluted in water and then applied by resin emulsion, dipping, etc.

In addition to the compounds of the present invention, the treatment bath may also contain finishing agents such as softeners, antistatic agents, water repellents, surfactants, dyes, pigments, and water-soluble substances such as poval, carboxymethylcellulose, methylcellulose, ethylcellulose, and sodium alginate. Polymers can also be added to the treatment bath.

Textile products can include woven, knitted, and nonwoven fabrics made of natural fibers, chemical fibers, and synthetic fibers such as cotton, rayon, vinylon, nylon, acrylic, and polyester.

The treatment conditions for resin emulsion are not particularly limited, but in the case of dipping treatment, usually textile products (squeezing ratio 40 with a mangle) are used.
It is squeezed to ~300% and dried in a dryer at a temperature of 60-150°C. When processing by coating, spraying, etc., the processing may be performed under approximately the same conditions.

Examples will be described below, but the present invention is not limited to the following examples. In the examples, "parts" indicate parts by weight.

Example 1 5 parts of a 5% aqueous solution of polyethylene glycol (MWaOOO) dicetyl ether and 75 parts of water were added to 20 parts of Sunbren UX-3500 (urethane emulsion manufactured by Sanyo Chemical Industries Ltd., C40% solids) and mixed by stirring uniformly. An emulsion and a treatment solution were prepared. After immersing a polyester nonwoven fabric in this treatment solution and squeezing it with a mangle (squeezing rate 1
20%), and dried at 100°C for 10 minutes.

As a comparison, polyethylene 1 glycol (MW6
, 000) without the addition of dicetyl ether was treated in the same manner. The results showed that the product without additives was very hard and had little elasticity and had a paper-like texture, but the product with additives was more elastic and voluminous.

It had a good texture with a uniform feel. This difference in texture is due to the fact that the emulsion particles do not migrate when the compound of the present invention is added, and the resin adheres uniformly.
This is thought to be due to the resin migrating in the case of additive-free products.

Example 2 To 10 parts of Sunbren UX-2700 (urethane emulsion manufactured by Sanyo Chemical Industries, Ltd.) [50% solid content], 5 parts of a 5% aqueous solution of the compound of the present invention (see Table-CI)) and 85 parts of water were added. The emulsion treatment liquid was prepared by uniformly stirring and mixing.

A polyester nonwoven fabric was immersed in this treatment solution and squeezed with a mangle (with a squeezing rate of 100% and dried at 100°C for 10 minutes.The results are shown in Table 1).The compound of the present invention was added. All of the samples had a soft and elastic texture, but the sample with no additives had a hard, paper-like texture.This may be due to migration of emulsion particles as in Example 1. It can be considered that the difference is whether or not.

Table - Item 0 Example 3 A polyester knitted fabric was immersed in the same treatment bath as in Example 2, squeezed with a mangle (squeezing ratio 100%), and then dried at 100°C for 10 minutes. The results are shown in Example 1. Similarly, those without additives had a hard and paper-like texture, but those containing the compound of the present invention all had a soft texture with a voluminous feel.

Example 4 20 parts of Sunblen UX-3500, 5% polyethylene glycol (MW 6,000) dicetyl ether aqueous solution, 5 parts, and 75 parts of water were added vertically to an emulsion treatment solution for 22 hours.
cm, width 5mm polyester non-woven fabric is dipped and squeezed with a mangle (squeezing ratio 120%) immediately lengthwise and widthwise 10mm (!I1
The nonwoven fabric was sandwiched between two glass plates in step 1 and dried at 1-00℃ for 10 minutes, then the two glass plates were removed and dried at 100℃ for 10 minutes.The nonwoven fabric was easily dyed by urethane resin, and polyester Alloy dye that is difficult to dye (Kayak)
The sample was immersed in a 1% aqueous solution of Alan Red BL (manufactured by Nippon Kayaku Co., Ltd.) for 10 minutes, and then washed with water to remove excess dye. Figure 1 shows a nonwoven fabric treated with the addition of the compound of the present invention, and Figure 2 shows a nonwoven fabric treated without the addition of the compound of the invention. Figure 1 shows that the urethane resin is evenly adhered because it is uniformly dyed, and the white part of Figure 2 is not dyed, indicating that the urethane resin is not attached. This shows that the emulsion particles in the area sandwiched between the glass plates migrate with the evaporation of water when the migration inhibitor of the present invention is not used, but do not migrate at all when it is used.
