Description

[Detailed Description of the Invention] The present invention provides excellent flexibility and antistatic effect to clothing, etc., even when used in both rinsing and drying processes in the washing process of textile products such as clothing. The present invention relates to articles for processing textile products that can be used to process textile products.

Conventionally, a common method for imparting flexibility to clothing has been to add a liquid softener during the washing process. However, with the spread of clothes dryers, from the viewpoint of simplifying washing operations and effective use of fabric softeners,
A variety of fabric softeners have been proposed in which an absorbent base layer is impregnated with a softening component as a fabric softener that imparts flexibility and antistatic properties when drying damp clothing in a dryer after washing. 4, e.g. an absorbing group 1 with a specific absorption capacity
- impregnated with a fabric softener having a melting point of 100T to 170°F (Special Publication No. 47''L19594), and non-woven fabric coated with a waxy substrate and coated with a fabric softener on the outside (Special Publication No. 47''L19594). 47-40120).

Furthermore, in order to improve usability by lowering the melting point of di-long-chain alkyl di-short-chain alkyl quaternary ammonium salt, which is one of the main fabric softeners, we developed a fatty polyhydric alcohol ester (% 118089/1989). , lanolin alcohol or its aliphatic carbo/acid ester (JP-A-52-
This is an improved composition that uses a melting point depressant such as 124998') in combination. When these are used in a dryer, although they impart flexibility to clothing, they do not provide sufficient antistatic properties. Especially in a dryer, clothing made of synthetic fibers can become extremely statically charged due to repeated friction between clothing and clothing.
Static electricity often causes discomfort to the user. It is also said that these softeners can be used in the rinsing process of laundry, but the softening effect is much inferior to that in a dryer, so it is inconvenient for the user.

Therefore, an object of the present invention is to provide an article for treating textile products that can impart excellent flexibility and antistatic properties to clothing when used in both the rinsing and drying steps of the washing process. be. The object of the present invention is to prepare an absorbent material (a product obtained by soaking a cationic fiber softener and l'l: constant fat) (b acid amide compound and fatty acid ester or specific ethylene oxide adduct in X). By using this, the cationic fiber softener is improved, and when used in the rinsing process, the cationic fiber softener is made into fine particles, providing excellent antistatic properties equivalent to those used in a dryer. This is based on the knowledge that it is effective.

5) Any space that can hold one mJ (C,) is sufficient. For example, paper, woven fabrics, non-woven fabrics, sponges, etc. Among these, nonwoven fabrics and sponges are preferred from the viewpoint of usability. Examples of nonwoven fabrics that can be used include cellulose, rayon, polyester fibers, etc. treated with a binder, polyolefin fibers mixed therein without using a binder, and spunbond fabrics. The sponge is preferably a plastic foam such as polyurethane foam or polyester foam having open cells.

In addition, a flexible sheet-like material is preferable from the viewpoint of presentation and use, and in particular, the apparent specific gravity is 0.01 to 0.03 and the porosity is 95.
Plastic homes such as sheet polyurethane homes with a thickness of 1 to 5 mm and a thickness of 10 to 5 mm

The present study is about a garment treatment article made by impregnating an absorbent material with components (A), (B), and CC), including component (4).
(As a result of the synergistic action of Q, especially when used in the rinsing process, an excellent antistatic effect equivalent to that used in the drying process is exhibited.Ratio of component (A) (B> can be selected arbitrarily, but if the mixing ratio of component (5) and component ω) is within the range of 9515 to 40/60, preferably 9515 to 60/10 (weight ratio), the rinsing step The flexibility of component (A) (

When the weight ratio is within the range, flexibility in the drying step and the rinsing step will be good.

Therefore, a product in which the components (At (B) and (C)) are within the range that satisfies the above two blending ratios has excellent flexibility and antistatic properties even when used in both the drying process and the rinsing process. This is particularly preferable because it exhibits the following properties.

In addition, the amount of components (A), (B), and (Q) impregnated into the absorbent material can be selected arbitrarily, but in the rinsing step, when used, the components (A), (B, and C) become fine particles. In order to perform the process quickly, it is preferable that the proportion occupied by the component (Al (B) .

A mixture of component (5) (B) whose ratio 1F was measured at temperature was impregnated to a predetermined void occupancy.

The product of the present invention further includes a small number of fluorescent brighteners, dyes, pigments,
Flavoring agents, etc. can be added, but these and other ingredients (~

It's a bit cumbersome to keep it within the range of ~50 volumes.

According to the product of the present invention, it is possible to impart excellent flexibility and band resistance to clothing, etc., even when used in either the rinsing process of washing or the rolling process. In particular, it has an excellent antistatic effect on clothing made of synthetic fibers such as acrylic fibers and nylon, and eliminates the discomfort caused by static air to the user. Next, the invention will be explained in detail with reference to examples. 1. The manufacturing method of the hawk a product processing article, the textile product processing method, and the performance evaluation were performed by the following methods.

After heating and melting the mixture (A), (B), and (C), and immersing the absorbent material in this solution, a squeezing roller is used to process the mixture into the sheet-like absorbent material. The amount of impregnation was adjusted so that the void occupancy was at a predetermined value. Next, the rice cake was cooled to room temperature and cut into predetermined sizes.

Processing method for o#I textile products (processing in the drying process) Cotton towels and acrylic cloth (acrylic jersey) were used as the 4 textile products, and after washing these with a commercially available detergent, they were thoroughly rinsed and squeezed to a dehydration rate of 140%. , the dry weight is 1/1 (
A total of 311 kg (cotton towel to acrylic cloth) was placed in a vertical rotary household dryer. After adding one article for textile processing, it was dried at about 50-70°C for 45 minutes.

(Treatment in the rinsing process) Water 301 was placed in the rinsing bath of the washing machine, and a cotton towel and acrylic cloth similar to those used in the drying process were placed therein. Next, add 1 article for textile processing to 3 liters at room temperature.
Rinsed for minutes.

After the fabrics treated in this way were air-dried indoors, the fabrics for evaluating the softening effect were left at 25°C and 65% 1 for 24 hours, and the fabrics for evaluating the antistatic effect were left at 20°C and 45% 1 (
It was left under Jl conditions for 72 hours and exposed to various tests.

- Performance evaluation (a) Flexibility: The feel of the test fabric before and after treatment was compared and evaluated based on the following criteria.

Example 1 As an absorbent material, a sheet-like polyurethane foam having a thickness of 2 mm, an apparent specific gravity of 0.014, and a porosity of 99% and having open and closed cells was used. impregnated with a mixture of lauroyl jetanolamide (component B) and POE (p = 2) nonyltunyl ether (component C) with varying blending ratios (weight ratio) to produce a product with a void occupancy of 20%, It was cut into 20 ClrL1 length and 7 CrIL widthwise. Performance was evaluated using this. The results are shown in Table-1.
