Problems solved by technology

[0003] Traditional thermal clothing such as down jackets mainly increase the thickness of the fabric to increase the space of the still air layer of the fabric to improve the thermal effect, and the clothing is bloated and single
New thermal insulation fabrics usually adopt methods such as vapor-depositing metal on the surface of the fabric, composite metal layers, etc., using the specular reflection properties of metals to inhibit the heat radiation from the human body, such as Columbia's OMNI-HEAT heat reflection technology, but there are strong heat conduction, lack of coloring, Disadvantages such as poor air permeability and moisture permeability, and inability to wash
The UNIQLO HEATTECH thermal underwear that is currently sold in the market is a hygroscopic heating fiber. When the fiber absorbs water, the hydrophilic groups in the fiber molecules combine with the water molecules, and release heat when the water is liquefied. However, the heating effect is limited, and the warmth retention effect is general. Heating yarns are mostly made of chemical fiber blends, which are not as comfortable as cellulose fibers, and are not suitable for people with skin allergies to wear next to the body

Abstract

The invention discloses a method for processing a multilayer thermal knitted fabric (Smart Thermal). The method includes processing steps of 'sandwich' multilayer weaving, automatic scutching and rolling, pre-shrinking, preliminary type approval, pretreatment, dyeing, hydrophilic soft finishing, dehydrating and drying and type approval. The method has the advantages that the multilayer thermal knitted fabric is a comprehensive thermal fabric as compared with an existing product with a single thermal function and comprises independent heating materials with moisture absorption heating and far infrared heating functions, large quantities of thermal elements are added into the multilayer thermal knitted fabric in the design, heat of garments can be locked in the multilayer thermal knitted fabric to be fed to human bodies, and accordingly the multilayer thermal knitted fabric is a comprehensive thermal product in the true sense; the multilayer thermal knitted fabric produced by the aid ofthe method is soft and comfortable, is high in elasticity, has diversified far infrared heating, natural antibacterial, moisture absorption heating and heat storage thermal composite functions, has amoderate thickness and is suitable for diversified thermal garment styles.

Description

technical field [0001] The invention relates to knitted fabrics in the field of textiles, in particular to a multi-layer thermal knitted fabric (SmartThermal) and a processing method thereof. Background technique [0002] The most important function of clothing is to maintain the normal temperature of the human body and make the human body feel comfortable. With the fashion of clothing, it is troublesome and sometimes difficult to maintain a suitable temperature for the human body only by increasing or decreasing the thickness of the fabric. At the same time, due to climate change in recent years, the number of cold days in winter has gradually increased, and extreme cold weather has appeared in many places. How to wear fashion and keep warm in the cold winter and make warm clothing lighter and thinner has become consumers' demands for winter clothing fabrics. With people's increasing requirements for high-grade clothing and functional finishing fabrics, the development of ...
