Description

Double-sided fusible interlining and manufacturing method thereof

technical field

The invention relates to the field of textiles, in particular to a double-sided adhesive interlining and a manufacturing method thereof. By coating the adhesive resin on the front and back of the base fabric to obtain the characteristics different from the traditional one-sided adhesive interlining, it has a broader market, to a large extent, it has broken through the limitations of the interlining, and has a certain advanced sex.

Background technique

As a traditional industry, interlining has formed a specific range of use in people's consciousness. Its purpose is to assist fabrics to obtain new advantages that are different from the original fabrics such as style, feel, and appearance. Although this is the function of the interlining itself, with the development of society and the continuous improvement of requirements, the interlining industry also has a higher pursuit goal: how to break through the limitations of the original industry and expand its use while retaining its characteristics .

Contents of the invention

The object of the present invention is to find a kind of double-sided fusible interlining and its manufacturing method, which can be used to bond the front and back sides of the same or different kinds of fabrics or other decorative handicrafts, so as to obtain products that can meet the needs of customers. .

The feature of the double-sided adhesive interlining cloth is: the two surfaces of the base cloth are respectively coated with an adhesive layer.

The adhesive layer is a dotted resin coated on the surface of the base cloth; the resin is polyamide, polyethylene, copolyamide, polyester, polyvinyl alcohol resin.

The manufacture method of described double-sided fusible interlining comprises:

Scouring: Add water and scouring additives to the required amount in the liquid tank of the scouring machine to prepare a scouring liquid. After heating up to 50-70°C, put the base cloth into the liquid tank to make the scouring liquid and the base cloth together in the liquid Rotate circularly in the cylinder, then raise the temperature to a scouring temperature of 80-100°C, and after scouring for 15-25 minutes, drain the scouring liquid, add cold water to wash and take it out, and then open the scouring base cloth through an open-width machine, and dry it Machine drying, drying temperature is 80 ~ 120 ℃;

Finishing: Add water and finishing liquid into the liquid tank of the finishing machine to make the base cloth dip and roll the finishing liquid, and then enter the drying and setting machine in the finishing machine for drying and setting. Dry setting temperature: 100-200°C; speed 25-35 m/min;

Bonding: Coat one side of the base fabric with dotted resin, the setting temperature is 100-170°C, and the processing speed is: 25-45 m/min; use the same method to coat the same or different dots on the other side of the base fabric Shaped resin, stereotyped tenter.

Auxiliaries for scouring metal ion chelating agent 0.1-0.4 g/L, desizing agent 1.0-2.0 g/L, bath softener 1.0-2.0 g/L, sodium carbonate 1.0-3.0 g/L, the rest in the refining liquid for water.

The amount of additives in the finishing liquid is 1-5 g/L softener, 1-5 g/L waterproof agent, 0.1-0.3 g/L antistatic agent, and 1-3 g/L anti-yellowing agent. The rest of the liquid is water.

When bonding, the primer is evenly coated on the surface of the base cloth in dots by using the mesh cylinder transfer method, and then the powdery resin is sprinkled, and then the excess resin is absorbed to make the place where the primer is on the base cloth sticky. Put on or keep the resin, and then carry out infrared heating at a temperature of 220-270°C to dry the primer and fix it on the surface of the base cloth, and then enter the drying room to shape the base cloth. The temperature of the drying room is 100-170°C, and the processing speed is 25- 45 m/min.

During drying and setting, there are nine drying and setting rooms. The temperature of each room is as follows: the first room is 100-110 °C, the second room is 100-110 °C, the third room is 100-110 °C, the fourth room is 130-140 °C, and the fifth room is 130-140 °C. 150～160℃, six chambers 170～180℃, seven chambers 190～200℃, eight chambers 190～200℃, nine chambers 190～200℃.

After scouring and before finishing, the base fabric is dyed first: add the dye liquor prepared by water and auxiliary agents in the high-temperature liquid flow dyeing machine, and the amount of auxiliary agents added is 2-5 grams per liter of acid dye, leveling agent 1-4 g/L, 1-4 g/L pH regulator, 1-4 g/L softener in the bath, dye the base fabric in the dyeing solution at 80-100°C for 15-25 minutes.

Soaping after dyeing: soaping in the soaping solution prepared by water and soaping agent for 10-20 minutes, the temperature is normal temperature, and the content of soaping agent is 1-3 g/L; then washing in water: washing in clean water , the time is 10-20 minutes, and the temperature is normal temperature.

In the process of processing, different processes can be used to obtain different styles and feels:

1) During refining: Since polyester does not contain cotton, there is no primary inclusions such as glue, cotton wax, cotton seed shell, etc., and only the secondary inclusions need to be removed during the refining process. At the same time, due to the particularity of the long fiber, the gray cloth of the long fiber must be smelted in a relaxed state, while removing impurities, NaOH, H ₂ O ₂ and other chemicals must be added to corrode and thin the long fiber fiber for removal. Gloss and easy to dye, soft, elastic and other properties.

2) Dyeing: Make the dye attach or fix to the fiber or enter the inside of the fiber, so that the fabric can obtain a beautiful, uniform and firm color, which is the same as the required sample.

In order to maintain the good elasticity of the long-fiber fabric, the dyeing of the long-fiber continues to use a high-temperature and high-pressure liquid flow dyeing machine or a high-temperature and high-pressure liquid jet dyeing machine in a relaxed state, and is dyed with disperse dyes or acid dyes or disperse/direct dyes.

3) Finishing: the process of performing sensory treatment on gray fabrics by physical or chemical methods.

After refining and dyeing, the gray cloth that is completely relaxed and shrunk is made to a certain width, and then heated and shaped. During this process, softeners and antistatic agents are added to infiltrate the gray cloth and dried, so that the gray cloth not only has a flat appearance, but also has certain elasticity and antistatic ability after finishing.

4) Bonding: This process is the key to the technology of double-sided fusible interlinings. The hot-melt resin is evenly spread and fixed on the base cloth by the method of net cylinder transfer or slurry coating method. The specific operation is: after the base cloth passes between the roller and the net cylinder, the slurry (the slurry is a colloid composed of polyacrylic acid and polyacrylate copolymer and water) comes out from the mesh of the net cylinder and sticks on the net in dots. On the base cloth, the base cloth continues to move forward, and a layer of powdery resin is sprinkled on the powder spreading device, and then, after being vibrated by the vibrating device, the powdery resin is evenly sprinkled on the base cloth, and then passed through the air pump and After recycling the device, absorb the excess powdery resin located between the dotted slurry, so that the powdery resin is uniformly distributed on the surface of the base cloth in dotted form, and it will be fixed by raising the temperature in the subsequent process. One side of the base cloth is coated with resin, and the other side of the base cloth is processed by the same processing method. Since the fixing temperature of the machine is not too high, it has little effect on the formed coating resin, and its performance will not be affected. As for the adhesion fastness on both sides, the same or different resins can be coated or the same or different meshes can be used to obtain satisfactory adhesion according to customer requirements.

The greatest contribution of the present invention is to break through the limitation that interlining can only be used on fabrics as garment accessories, and turn two completely independent things into a whole like a bridge, which can not only retain the original characteristics of interlining but also endow interlining with new features. style of. With this bridge, as long as the appropriate texture is used, the corresponding double-sided interlining can be made and widely used in handicrafts, decorations and other required industries, so its market prospect is broad. At the same time, although double-sided fusible interlinings are also seen in the market, their essence is quite different: A) The double-sided interlining on the market adopts a principle similar to that of solid glue to form a smooth film on the base fabric. Layer, the film layer is partially melted under the condition of heat so that it is bonded to the fabric in a surface manner, so as to achieve the intended purpose, but this kind of adhesive is affected by water flow, temperature and mechanical force during the initial washing process. B) the present invention adopts hot-melt resin, and the uniform hot-melt resin melts in the process of heating and completely has an affinity with the fabric, penetrates into the fiber, and directly contacts the fiber in a point-like manner. Once formed, the resin The crystal structure is fixed, and its corresponding physical and chemical properties are also stable, so it can withstand repeated washing without falling off and foaming. This is the difference between glue and resin essence, the former is physical bonding, while the latter is chemical bonding.

The double-sided fusible interlining of the present invention is developed for the needs of the current market. It not only has the characteristics of general fusible interlinings, but also is different from general fusible interlinings. Its research and development is based on some special requirements: Two pieces of different or the same fabrics are glued together to form a garment with a special feel and style.
