Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a padded cotton, particularly a padded cotton made of feathers that has both bulkiness and an antistatic effect, and is characterized by having alumina sol adhered to the surface of the feathers.

It is widely known that feathers can be used as filling cotton for comforters, cushions, and clothing, but as a result of long-term use, the bulk of the feathers gradually decreases, and they lose their elasticity, resulting in poor usability. It has been recognized that it has negative effects, and also generates static electricity during use, attracts fine dust, and gradually becomes contaminated.

Therefore, the present invention aims to obtain cotton padding made of feathers that does not have the above-mentioned drawbacks, and as a result of various studies, by attaching alumina sol to the surface of the feathers, it is possible to maintain bulkiness over a long period of time and prevent static electricity. It was possible to obtain cotton wadding made of feathers that has both excellent performance.

However, the cotton pad made of feathers of the present invention is prepared by first completely washing and removing dust mixed in the feather raw material, and then adding alumina sol, that is, an alumina hydrate having a colloid size of 5 mμ to 20 μm. A water-dispersed colloid containing ~0.5% by weight was sprayed onto the dust-free feathers using a spray method, and dried at 80-110°C in a rotating drum dryer at 12-3°C.
After drying for 0 minutes, it is possible to obtain cotton padding consisting of feathers with an alumina coverage of 05 to 0.05% by weight.

Now, I use 60% gray down (for the gray lines that grow densely around the chest of waterfowl) and small feather (length 6.5%).
Table 1 and Table 1 show the bulkiness of standard feathers mixed with 40 wt. Shown in Figure 1.

As is clear from the table, the standard feathers treated with alumina sol are
The specific volume is improved by 10-25% compared to untreated standard feathers.

Table 1 Notes 1) FTC method % formula % A 25 g feather sample was put into a cylinder with an inner diameter of 32.4 cTL and a height of 50 cm, a disk with a diameter of 31.9 cm and a weight of 108 g was placed, and the disk was The height of the feather when the support string is loosened and the height of the feather 1 minute after the load is applied are measured on a scale, and each value is taken as the bulkiness at the beginning and after 1 minute has passed.

Calculation of specific volume - Face of the shield
Put it in the cylinder of rrL, diameter 24cm.

A disk weighing 66g was placed, and 24 hours passed. Measure the height of the feathers after passing with a scale. Make it bulky.

Calculation of specific volume is the same as the FTC method.

3. Alumina sol AS-100. As-200 All product code numbers for alumina sol manufactured by Nissan Chemical Industries, Ltd. AS-100 contain cl- as a stabilizer and have a pH of 2.5.
Viscosity at ~4.5.25'C&C (by B-type viscometer) 100-10000C,P.

So, 5A-200 contains the stabilizer I, CH3COO-, and the viscosity at PH4.0-6.0.25℃ is 5O
-3000CP, except for specific gravity.

Particle shape 9 Particle size, charge, etc. There is no difference in physical properties between the two.

Furthermore, in order to confirm the effects of the present invention, the following tests were conducted on feathers having the composition shown in Table 2.

First, Table 3 shows the analysis results of the above two types of feathers.

As is clear from Table 3, alumina sol-treated feathers have less oil and fat on the feather surface than untreated feathers, and the oxygen coefficient has been reduced to 1/2, reducing the stickiness and odor of the feathers caused by oxidation of oil and fat. It also has the effect of preventing feathers from rotting.

Note to Table 3 Transparency is the turbidity G of the washing water. The higher the measured value, the more refined the feathers are.

Next, we measured the bulkiness of the two types of feathers using the mini-tic method and calculated the specific volume.As a result, the specific volume of the untreated feather was 340C1t/g, and the specific volume of the alumina sol-treated feather was 380C1ll/g. An improvement of 12% was observed.

In addition, each feather was placed in a rotating drum dryer for 3 hours, rotary dried at a temperature of 60°C, and subjected to a so-called tumbler treatment.The bulk of the feather was then measured using the mini tick method, and the specific volume was determined. As a result, the specific volume of untreated feathers is 320
0 gauze, specific volume of alumina sol treated feather is 356c
An 11% improvement in a/g was observed, and the bulk of the tumble-treated feathers decreased by approximately 6% in both untreated feathers and alumina sol-treated feathers compared to those without tumble treatment. did.

The above results are shown in Table 4 and Figure 1G.

Table 4 Note 1) Minitic method Internal diameter 29 accommodated 20g of feather sample Stack the measuring plate from the top of the cylinder a. Extremely lower the measuring plate. Measure the height of the feathers when it stops Make it bulky. Calculation of specific volume is F The same applies to method C.

Next, a so-called European-style Western-style futon with lattice-like quilting on the entire surface, which is 1/2 the size of the standard size, was made using the untreated down and the alumina sol-treated down as padding, and the bulk of the duvet was measured. The bulkiness of the futon was measured using a machine.

The duvet bulkiness measuring device generally has the configuration shown in FIG. The futon 6 placed on the futon 6 is once compressed from above by the load plate W1 on which a load of 1 g is placed, and then when the load of 1 g is removed and the load plate stops rising due to the restoring force of the futon 5, the measurement is carried out. The height from the top surface of the stand 4 to the bottom surface of the load plate W1 is read on a scale 6 and is defined as the bulk height.

The futon used for measurement is usually a standard size futon (1) 5 x 210 cm in side size and 1.5 kg of cotton padding, which is folded into four and placed on a measuring table for measurement.

However, in the present invention, as mentioned above, measurements were taken on a V2 size futon, and as a result, the bulk of the futon using untreated down as the filling was 17.2 cm, and the bulk of the futon using alumina sol treated feather as the filling was 17.2 cm. The bulk of the futon used as a futon was 18.3 cm, and it was found that the futon used as a padding was approximately 7% bulkier when filled with alumina sol-treated feathers.

Furthermore, the bulkiness of the two types of futons was measured after dry cleaning, and there was almost no difference between the bulkiness before and after cleaning. As a result of measuring the bulkiness and calculating the specific volume, the specific volume of the untreated feather was 274 ca/g, and the specific volume of the alumina sol treated feather was 287 CrVg, a difference of 5%.

As described in detail above, the padded cotton of the present invention with alumina sol attached to the feather surface retains its bulk for a long period of time,
It is already known that alumina sol is a processing agent that maintains elasticity and provides a comfortable feel when used as filling cotton for futons, cushions, and clothing, and has good antistatic properties. , since the cotton pad made of feathers of the present invention with the alumina sol attached to the surface does not generate static electricity and does not attract fine dust and become contaminated.
This makes it possible to fully utilize the wonderful functions and bulk of feathers, and to obtain a sanitary padded cotton that is free from contamination.
