What fabric is the jacket made of? And why can it be used as outdoor clothing?
Overview
The jacket is a type of windbreaker, sometimes also called a windbreaker or raincoat. It is a functional windbreaker and one of the essential equipment for outdoor sports enthusiasts. It is also a “functional windbreaker”. coat”. Considering that its use environment is quite special, it can also be translated as “multifunctional outerwear”. Simply speaking, a jacket is a jacket worn when climbing to the summit, and now it is called a jacket. What people generally refer to when they refer to jackets is mostly called parka in the product catalogs of major manufacturers, and there is also a small amount of jacket. According to Webster’s Encyclopedia Dictionary, the word parka comes from Russian, and its original meaning is a leather pullover with a windkerchief from the Russian Arctic region. Later, it was extended to the general term for all pullovers or jackets with hoods and linings.
Property
The basic functions of a jacket are waterproof, windproof, breathable, wear-resistant, etc. The jacket is windproof and waterproof and does not have a thermal effect. The quality of the jacket fabric mainly depends on its waterproofness and breathability. On the premise that the waterproofness of the fabric is guaranteed, more attention is paid to the breathability of the fabric. through
The breathable fabric makes it dry and comfortable to wear. There are three major types of waterproof and breathable fabrics currently on the market:
① High-density fabric: A dense fabric made of high-count cotton yarn and ultra-fine synthetic fibers, which has high water vapor permeability and has a certain degree of waterproofing after water-repellent finishing sex. High density is characterized by good moisture permeability, good softness and drape, but low water pressure resistance, high defective rate, difficulty in dyeing and finishing, and poor hemming and friction properties.
②Coated fabric: It can be divided into two types: hydrophilic coating and microporous coating fabric. Hydrophilic coating If there are hydrophilic genes on the polymer chain with appropriate content and arrangement, they can interact with water molecules and use hydrogen bonds and other intermolecular forces to adsorb water molecules on the high-humidity side and pass through the polymer chain. The aqueous groups are transferred to the low humidity side for desorption. The coating is generally simple to process, and is characterized by low moisture permeability and low water pressure resistance. Due to the limitations of raw materials, technology and this method itself, it has been unable to solve the problem of moisture permeability, permeability,
And the contradiction between water pressure resistance and water washing resistance.
③Laminated composite fabric: It combines water permeability and windproof and warm properties, which has obvious technical advantages. It uses lamination technology to combine ordinary fabric E-PTFE into one body, complementing each other’s strengths and weaknesses. It is the main development direction of waterproof and breathable fabrics at present.
