Discussion on Low Temperature Port Treasure

2022-03-16

Today, let Cheng Guan introduce what is a low-temperature port treasure. The so-called low-temperature port treasure is used under the heel of the shoe to make the heel play a fixed role. The material used is a bit like cardboard, which is relatively hard, but glue is used when fixing the low-temperature port treasure and the shoe. The low temperature port treasure according to the material is generally divided into the following three kinds 1, leather pulp low temperature port treasure Soaking water softening method, this kind of low-temperature port treasure is made of cowhide midsole leather as the material of low-temperature port treasure, which is also the softening method used to make leather shoes by hand. At present, Italian leather shoes are trapped in traditional ideas, and this kind of low-temperature port treasure is often used, which is not in line with economic benefits. 2, chemical film low temperature port treasure Soaking solvent (toluene) softening method; this kind of low-temperature Hong Kong Bao immersion solvent can be softened, which is one of the revolutionary shoe materials in the shoe industry in recent years. Its characteristics for soaking solvent can be very soft, the most conducive to footwear molding, without adding or strengthening any treatment, drying and cooling can achieve a stiff effect, for the shoe industry to use more ways. Advantages: cheap, easy molding. Disadvantages: thick, long forming time. The worst elasticity. 3, hot melt adhesive low temperature port treasure Heating softening method: heating (about 100-120 degrees) is used to soften the "hot melt adhesive" pre-pressed to the lining position in front of the shoe, so as to facilitate gang forming. its advantages are fast, thinner and more elastic than ordinary low-temperature port treasures. Disadvantages: molding difficulty is high, heat control is not easy. Dongguan Chengguan Enyou Material Technology Co., Ltd. is a Taiwan-funded professional hot melt adhesive manufacturer. The company has achieved advanced and excellent development since it was put into production in 1980. The company has 5,000 SQM in its production workshop and seven advanced production lines with a daily output of 100,000 SQM. The main products are: hot melt adhesive molding network, Dongguan hot melt film, low temperature Hong Kong Bao, Hong Kong Bao, hot melt film, hot melt adhesive film, etc. Very professional technical support.

The selection method and precautions of hot melt adhesive film: There are many types of hot melt adhesive film, and it is particularly important to choose the one that suits you according to the thickness and melting point. Hot melt adhesive film selection methods and precautions: 1, what is the need to bond the material? Different materials of hot melt adhesive on different materials of different materials, the degree of adhesion to all materials (such as polyurethane) is not greater than all other glue. For example, polyurethane is very strong to textile fabrics, and the adhesive strength to PE plastic is almost zero.

Hot melt adhesive film is a kind of plastic adhesive, which belongs to environmental protection chemical products. Its physical state can be changed with temperature change within a certain temperature range. The chemical characteristics of hot melt adhesive film are unchanged, and it is non-toxic and tasteless. Hot melt adhesive film is used in the bonding between two different substances, not only the bonding performance is superior, but also the washing resistance is relatively strong, and become a lot of heat-resistant textile seamless bonding heat transfer material.

Hot melt adhesive film is a kind of film with a certain thickness made of materials that can be melted and bonded to the adherend at normal temperature, without any stickiness, but as long as it passes through high temperature, it immediately shows its stickiness, and the fabric to be compounded can be successfully compounded quickly without any trace of glue. At present, the main hot melt adhesive films on the market are: PA, PES, EVA, EAA, TPU, etc. The characteristics of each hot melt adhesive film are also very different. Therefore, when selecting the hot melt adhesive film for compounding, one must understand the needs of the hot melt adhesive film and the composite products, so as to correctly select the appropriate hot melt adhesive film!
