Description

[Detailed description of the invention] (Industrial use distribution) FIELD OF THE INVENTION The present invention relates to cleaning fabrics.

(Prior art and its problems) Eyeglass lenses, cameras and other optical devices, mirrors and window glasses, polished or plated metal products, painted products, elegant furniture, lacquerware, tableware, glass products It is desirable that the surfaces of various products such as lint-free products be clean and clean, and cleaning cloths and soft papers should be used to keep them beautiful.

Many of these cleaning cloths and papers are made of cellulose-based fibers. Although fibrous materials such as cellulose have considerable cleaning power, they are inferior in strength and durability. For example, it is common for fiber fragments to fall off the fabric during cleaning, creating dust.

On the other hand, synthetic fibers are superior in terms of strength and durability, but
It was inferior in terms of cleaning power and was rarely used in practice. However, in order to overcome the drawbacks of this synthetic fiber, extensive research has been carried out, and for example, it is reported in Japanese Patent Publication No. 59-30149 that more than 25% of the pongee that forms the surface that touches the cleaning material is 6 It has a surface area of 0 0 0 om" or more, a polygonal or similar shape, and an aspect ratio of 2.
A wide surface area man-made fiber cleaning cloth having a shape that is a combination of six or more flat portions has been proposed. This cleaning cloth has excellent cleaning power against oil-based stains, but because it is made of synthetic fibers, it has the problem of lacking a luxurious feel.

The present invention has been made in view of the above-mentioned problems, and provides a cleaning cloth that has excellent cleaning ability for water-based and oil-based products, has excellent durability without generating fuzz, and has a luxurious feel. It is intended for the purpose of providing.

(Means for solving the problem) The above-mentioned purpose is to clean two fibers forming the surface that comes into contact with the object to be cleaned.
5% by weight or more of the silk fibers have a surface area of 600 G am' or more per gram, and the fibers forming the surface that comes into contact with the object to be cleaned have a loudness of 6μ or less. This is accomplished with cleaning cloths.

The present inventors have been engaged in research on natural fibers for many years,
The fineness of the fibers that form the surface that accidentally comes into contact with the object to be cleaned is 5μ
We discovered that silk fibers with the following loudness (fiber splitting M of fibroin) have extremely excellent cleaning power, and as a result of investigating the phenomenon in detail, we found that the cleaning power for cleaning the surfaces of glass products, etc. The present inventors have found that the material is particularly excellent when the surface area per weight is large and the fiber fineness is small, and the present invention has been completed.

For example, if the fineness of normal silk fiber is 10μ, the surface area is 1
2,000 to 3,000 cm" per unit, and the cleaning power is extremely poor.

The cleaning power here refers to the ability to remove dirt, fog, etc. from the surface of the glass product, etc. For example, when the surface of a mirror that is dirty with fingerprints is gently wiped with a cloth, the cleaning power increases as the number of times it is wiped is reduced to make it look more beautiful. To erase fingerprints from a mirror, it takes 20 to 30 times to wipe with tissue paper (soft thin paper) by pressing lightly with your hand.

Similarly, 20 to 30 times are required for cotton cloth (raised product), and 10 to 20 times is required for the above-mentioned silk fiber cloth. On the other hand, with the product of the present invention, fingerprints and the like can be wiped off with just a few wipes, and in most cases five or fewer wipes.

According to the findings of the present inventors, the larger the surface area per gram of fiber M (hereinafter simply referred to as surface area), the greater the cleaning power. In order to achieve the object of the present invention, the surface area of the silk fibers forming the surface that comes into contact with the object to be cleaned needs to be at least S O O am', preferably at least II 000 om.

Furthermore, according to the findings of the present inventors, the finer the Im fiber, the greater the cleaning power. In order to achieve the object of the present invention, the fineness of the silk fibers forming the surface that comes into contact with the object to be cleaned must be 6μ or less, preferably 5μ or less.

In the present invention, the silk fibers include raw silk or silk spun alone, or woven and knitted fabrics made by mixing and weaving them, and it is preferable that the densities of these four delicate structures are dense.

Next, a method for manufacturing a cleaning cloth made of silk fibers of the present invention will be described.

In general, it is known that in order to increase the surface area of silk fiber fabric and produce fine-grained loudness, it is sufficient to scouring it or handling it roughly in hot water, but the above method causes spots. However, you cannot obtain high-quality products.

Therefore, the silk fiber fabric is prepared by known methods - desizing, scouring,
Pre-treatments such as dyeing and fixing are performed, then a finishing agent is applied, the material is stuffed into tuffing bags, rolled in a rotary wafer, and then dried in a tumble drier.

In the above method, the finishing agents used include a softener, a silicone-based texture control agent, and, if necessary, a resin. As the softener, cationic and nonionic softeners can be used, but cationic softeners with good adsorption to fibers are preferable, and the amount of adhesion is 0.000% on the silk fiber fabric. 2-1. 8
Good weight percentage. As the silicone-based texture control agent used in combination with the softener, amino silicone is preferable, and the amount of adhesion is 0.1 to 1. 0% by weight is good.

In addition, in the case of silk fiber fabrics using raw silk, wrinkles are likely to occur due to large fibrillation during rotary wuffshering, so it is preferable to use a resin in addition to a cationic softener and amino silicone. As the resin, glyoxal-based, melamine-based, ethylene urea-based, urov-based, etc. can be used, but glyoxal-based 61 fingers is preferable from the viewpoint of texture, and the amount of adhesion is 0.9 to 2.0 weight per silk WUa fabric. %
Good. When applying a finishing agent to the above-mentioned silk fiber fabric, a conventional padding device is used and drying is carried out according to a conventional method, and when M fat is used in combination, curing is performed.

The above method is M'!

(Example 2 Next, the present invention will be specifically explained with reference to Examples.

As shown in Table 1, two types of silk fabrics were subjected to desizing, foil kneading, dyeing, and fixing treatments according to conventional methods.

Table 1 Using a padding device on silk fabric after fixing treatment,
Cationic beam softener (manufactured by Ipposha Yushi Co., Ltd., Vicron 29, solid content 20%) 6-layered silicone (manufactured by Osaka Chemical Co., Ltd., Texasilicon, solid content 12%) 3-layer [L-static] Inhibitor (Daiichi Kogyo Seiyaku former L Zureno:, -f'&20
) 2% by weight, the balance being 100% water, was applied to the tissue to give 60% of the basis weight of the tissue, and the tissue was dried at 120°C for 40 seconds using an infrared drying oven.

Next, the silk fabric with the finishing agent was sewn [1 was divided into two pieces (ζ folded along the width direction), and the edges were bound with thread at intervals of 10 oixx. The silk fibers were put into a 4.5mm reester net and put into a rotary washer.
The silk fabric was rolled at 1,550 yen, and then the silk fabric was dried in a tumble dryer.The product of the example of the present invention was obtained.

The above-mentioned crystal was placed in a 25°CG 5% constant temperature and humidity chamber at 481°C.
After storing it for more than 1x, cut it and measure the cleaning force to the liver value L. , 1 is listed in Table 2. In addition, the cleaning power is 1 on the mirror surface.
The grease was applied in an amount of mg/ont with the palm of the hand, and after 30 minutes, it was wiped with a sample cloth until it became beautiful, and the number of times (per 50 crn) was expressed.

Note: As is clear from Table 2, the product of the present invention has excellent cleaning power for cleaning surfaces such as glass.

Also, during the cleaning test, there was a good degree of adhesion between the fabric and the object to be cleaned (because there was little slippage), and it was easy to repeat the operation, and the fabric was free from fibers during cleaning. ．． There were no fragments that fell off.The appearance is made of silk fiber, giving it a luxurious feel.

(Effects of the Invention As detailed above) The cleaning cloth of the present invention has excellent cleaning power and excellent durability without generating fuzz, so it can be used for cleaning glasses, cleaning lenses, cleaning glass, and piano keys. It can be used for cleaning boards, painted surfaces, car windows and car bodies, metal surfaces, ceramics (food, artwork), floors, wood, etc., and it has a luxurious feel. It is extremely useful and can be used for both casual and formal purposes such as handkerchiefs and formal handkerchiefs.
