Description

High-strength TPU composite thermal fabric and preparation method thereof
Technical Field
The invention relates to a high-strength TPU composite thermal fabric and a preparation method thereof, and belongs to the technical field of textile fabrics.
Background
With the development of science and technology, various warm-keeping materials come out. At present, the heat-insulating material in the textile industry is a hollow fiber which is developed more rapidly, and the variety is also extremely rich. The natural hollow fibers comprise kapok, cotton, rabbit hair and the like, the hollow structure endows the kapok, the cotton, the rabbit hair and the like with unique style and performance such as good heat retention, light weight and the like, but the spinnability of the kapok is poor, and the pure cotton fabric has some defects such as wrinkling, heavy weight and not too fluffy, and the quantity of the rabbit hair is limited. The synthetic hollow fiber is made of terylene, chinlon, polypropylene fiber and the like, has light weight but poorer moisture absorption than natural fiber, and is uncomfortable to wear. Because the cotton fiber is thin and soft, the fabric of the cotton fiber has no stimulation to the skin, and is an ideal close-fitting material for human beings all the time, and particularly for infants with delicate skin, the cotton fabric is the best choice. The appearance of the cotton hollow core yarn not only can keep various performances of the traditional natural fiber, but also can meet some advantages of the artificial fiber. The cotton hollow yarn is produced by adopting a process of spinning the core-spun yarn, the outer wrapping fiber is cotton fiber, the inner core yarn is vinylon filament, so that the yarn has a double-layer structure, the core yarn is dissolved after the yarn is subjected to fiber removal, and the yarn forms the cotton yarn with a hollow structure, namely the cotton yarn with the hollow structure. The hollow yarn fabric has the advantages of the traditional cotton fabric, can overcome the defects of poor filling power and heavy mass per unit area of the traditional pure cotton fabric, has the advantages of both cotton fiber and artificial fiber, meets the requirements of light, thin and warm clothes, meets the requirement of modern pursuit of 'all natural' basic tone, and has higher added value of products. Has good moisture absorption and air permeability while keeping warm, and improves the wearing comfort.
Thermal materials can generally be divided into two broad categories: one type is a traditional passive warm-keeping material, which achieves the purpose of keeping warm by simply preventing or reducing the heat loss of human bodies, such as down, some animal furs, various natural fibers, chemical fiber hollow fabrics and the like. The other type is a novel positive heat insulation material, which not only follows the traditional heat insulation theory, but also can absorb external heat, store and transmit the heat to the human body to generate heat effect. Such as far infrared cotton, zirconium carbide thermal insulation fiber, etc. Most of the existing heat-insulating products sold in the market belong to the former heat-insulating materials, and the aim of reducing the heat loss of the human body is achieved by mainly utilizing the structures of fibers, yarns and fabrics and the heat resistance of clothes.
Thermoplastic polyurethane elastomer (TPU) is An (AB) n-type multiblock linear polymer. The A chain segment is composed of soft polymer dihydric alcohol, provides extensibility for the TPU material and is called as a soft segment; the B chain segment is composed of diisocyanate and small molecular diol, and the structure of the B chain segment is rigid, so that the B chain segment provides crystallinity and strength for the material and is called a hard segment. The TPU material has excellent mechanical properties such as high strength, high elasticity, high wear resistance, high flexibility and the like, and also has the properties of oil resistance, solvent resistance and common chemical resistance. These good properties make TPU useful in a wide range of applications, including medical and health applications, cables, tubing, automotive applications, apparel, footwear, films and sheets. The novel application of the thermoplastic polyurethane in the clothing industry is that the thermoplastic polyurethane can be made into a film to be attached to a fabric, so that the thermoplastic polyurethane gives a user good protection and comfort;
however, the mechanical properties of the materials are reduced due to poor bonding strength between the substrates of the existing prepared TPU film attaching composite materials, and the warm-keeping and moisture-permeable properties are also affected, so that the TPU film attaching composite materials are in need of effective improvement.
