The choice of raw materials for suede fabrics is mainly made of polyester microfiber as raw material. Polyester microfiber is a new product with high quality, high performance, high technology content and high added value. Its monofilament linear density is much lower than conventional polyester fibers, which gives it superior performance properties compared to conventional polyester fibers, such as moisture absorption, breathability, soft hand, fullness, elasticity, bulkiness and airiness.
Polyester microfibers have much lower linear density than conventional fibers, so they are different from conventional fiber dyeing properties, which are mainly reflected in dyeing rate, dyeing amount, dye lifting property, color depth, leveling property, and transferability. , color vividness and color fastness are obviously different from conventional fibers.
The increase in surface area due to low linear density first causes an increase in the degree of adsorption and desorption of the dye during dyeing. The increase in the degree of adsorption leads to an increase in the dyeing rate, a decrease in wet fastness and light fastness, and secondly, a dyed fabric. The color concentration is lowered. Improving the dyeing properties of polyester microfibers and fabrics has become a topic of great interest to companies.
The suede fabric is a special style textile fabric which is made of special textile materials and processed with special dyeing and finishing process. It is one of the most popular high-end fabrics in the domestic market. The suede feel and appearance are similar to natural suede. Its surface texture is similar to natural suede. After special finishing, it is fine and smooth, soft and full, more durable than natural suede, and easier to maintain. .
It is widely used in modern fashion, shoe materials, toys and furniture decoration, and is a novel decorative material. The suede is made of new raw material microfiber as the main raw material. After the reduction (grinding) process, it has not only soft hand feeling, good drapability, strong stability (no shrinkage or elongation due to cleaning), but also good ventilation. Sex, insect proof, anti-corrosion.
1 method of making suede and suitable raw materials
1. Method for making suede The method for making suede can be roughly divided into three types: a weaving method, a knitting method, and a non-woven method. Some companies in the domestic region use the first method.
2. The raw materials suitable for the production of synthetic suede weaving method In the development of synthetic fiber suede products, the raw materials selected are microfiber filaments, which are woven into fabrics and subjected to special dyeing and finishing processes. Processing, the formation of fine and uniform fluff on the surface of the finished fabric. The microfiber has the advantages of being fluffy, elegant, and soft to the touch, and the drape and softness of the microfiber fabric are excellent, and the hand feel is comfortable. There are various types of microfibers, which are suitable for suede-like polyester/polyester island type and polyester/japanese bell type. The island-type fiber is opened by dissolving method, and the orange-shaped fiber is opened by stripping method.
The method of dissolving the polyester/polyester island-type fiber by the dissolution method to make it into an ultra-fine fiber after opening is relatively reliable. Therefore, the weft is made of polyester 16.7tex/36fx371 (island silk) + 7.6tex conventional polyester coated double-twisted, and the polyester with l1.1tex is used as the raw material for developing suede products. At present, the raw materials used by some downstream enterprises in China are all polyester island silks purchased from Korea Huiweis Co., Ltd., which has 37 islands in the single fiber. After the sea is partially dissolved, the single fiber is 0.05De. It has a powdery and soft hand and a suede-like appearance. In order to ensure the stability of the quality of the finished cloth, domestic manufacturers are required to ensure that the raw materials are first-class products and are the same batch number. The cellosolve formulation uses a proprietary high-temperature alkaline water (150 ° C, pH = 13-14 water) process formulation that matches the feedstock.
