Description

Water-dropping manufacturing method

The invention relates to a method for manufacturing water-repellent down which can prevent the down jacket from losing moisture, and a down product made by the method.

Down and feathers grow on ducks and geese, while ducks and geese are waterfowls that can live on the water, so down and feathers are born with the ability to dial water. However, the fat attached to the surface of the down and feathers contains the odor of the original duck and goose. Before being applied to the product, it needs to be cleaned first, and most of the grease on the surface of the duck goose is removed, which of course reduces the water-repellent effect of the down. .

Feather and down have the characteristics of lightness and heat preservation, which keep hot air in the fabric, so they are processed into warm products such as down jackets, duvets or sleeping bags. When such a warm product is covered or covered on the user, it can retain the heat released by the user, thereby achieving the purpose of keeping the user warm and cold, and the weight is light, and does not affect the user's active body.

As mentioned above, feathers and down have the characteristics of high warmth, but they are very afraid of moisture. Feathers and downs are easily adhered to agglomerates due to moisture and moisture. At this time, there is no warmth, and in this state, Very difficult to dry and restore. If the body quickly discharges a lot of sweat or moisture, the tangled down will lose the ability to keep warm, causing the user to easily catch cold and catch a cold.

In view of the above reasons, the creator has invested a lot of research and development resources and spirit in this field, and hopes to solve related problems with novel technologies, and then bring excellent products to the society and promote industrial development.

In order to make the description more concise, the down system described in the present case is a mixture containing feathers and feathers, which will be described first.

The water-repellent down system made by the invention can prevent the feather from sticking after being damp, so even if the user discharges a large amount of sweat or moisture, the down will remain in the original state, and the hot air is retained therein to provide the wearer with warmth. Function to overcome the problems of conventional technology.

To achieve the above object, the water-repellent down of the present invention is coated on the surface of the down surface by a water-repellent layer, wherein the water-repellent layer is formed of a water-repellent agent containing a fluoride or a siloxane-based functional group. By the arrangement of the water-repellent layer, water can be prevented from remaining on the down, so that the downs are not affected and the bonding occurs, so as to overcome the shortcomings of the prior art.

In order to make the water-repellent layer well coated on the down, the method adopted by the water-dropping manufacturing method of the present invention comprises a soaking step, a bridging agent adding step, a water-repellent adding step, a stirring step and a dehydrating step. , drying steps.

The soaking step is to soak the washed down in a solution having a pH between 4 and 7, so that the down can be fully wetted to facilitate the subsequent bridging reaction: the bridging agent addition step will contain isocyanates or acrylics. The functional group bridging agent is added to the solution, and the weight ratio of the down and the bridging agent is 1:0.005 to 1:0.06: the water-repellent addition step is to add a water-repellent agent containing a fluorocarbon or a decane-based functional group to the solution. Medium, and the weight ratio of down and water repellent is 1:0.01 to 1:0.1; the stirring step is continuous stirring for at least 15 minutes after the addition of the bridging agent and the water repellent, and the feather can be solidified by continuous stirring. Fully react in the space, so that the water-repellent agent is evenly attached to the down; the dehydration and drying steps are after the reaction is completed, drainage and dehydration are performed to separate the down and the solution, and then the down is dried by hot air of 120 degrees Celsius or above. After the drying is completed, it is cooled to normal temperature to make a water-dropping down.

By the bridging reaction generated by the water-repellent agent and the bridging agent of the invention, the water-repellent agent can be properly coated on the surface of the down, and will not fall off due to the process of stirring, drying, wind blowing, etc., and the water-dropping and feathering produced The water-based property is good, the water-repellent layer is more durable and durable; in addition, the process of the invention is simple, can be mass-produced quickly and efficiently, reduces the cost incurred by the processing, and the yield of the water-dropping feather is extremely high and low. There is a problem that the water layer is not completely covered. In the process of the present invention, the weight ratio of the down to the solution may be between 1:20 and 1:35, and the bridge reaction can be fully reacted on the surface of the down by properly controlling the ratio.

Preferably, the weight ratio of the down and the bridging agent may further be between 1:0.005 and 1:0.05, and the weight ratio of the down and water repellent may further be between 1:0.03 and 1:0.09; A good ratio of the agent to the water repellent makes the reaction more complete.

More preferably, the bridging agent contains an isocyanate functional group, and the weight ratio of the down is 1:0.03 to 1:0.05; the water repellent contains a fluorocarbon functional group, and the weight ratio of the down is 1:0.03 1:0.09.

More preferably, the bridging agent contains an isocyanate functional group, and the weight ratio of the down is 1:0.005 to 1:0.03; the water repellent contains a fluorene-based functional group, and the weight ratio of the down is 1:0.05. To 1:0.07.

Preferably, the stirring step is continued for a period of up to 30 minutes.

Preferably, in the dehydration and drying steps, after the drainage and dehydration are completed, the down is first stirred and loosened before the drying operation.

Preferably, the dehydration and drying steps are performed by hot air at 120 to 140 degrees Celsius.

Preferably, the soaking step is carried out by adding glacial acetic acid to the solution to adjust the pH, and the pH can be further controlled between 4 and 5.

Preferably, the soaking step to the stirring step maintains the temperature of the solution between 20 and 60 degrees Celsius.

By using the water-dropping down process of the invention, it can be filled into a variety of down products, such as common down jackets, duvets, down pillows, etc., with good water repellency, the product can maintain fluffy and warm characteristics, and has better Quality.
