1. Clothing adhesive lining
Non woven fabric lining includes general lining and adhesive lining, used for non-woven fabric lining in clothing, which can endow clothing with shape stability, shape retention, and stiffness. It has the characteristics of simple production process, low cost, comfortable and beautiful wearing, long-lasting shape retention, and good breathability. Non woven adhesive lining is widely used and is the most commonly used type of non-woven fabric in the clothing industry. Non woven adhesive lining is a process in which non-woven fabric is coated with hot melt adhesive and directly bonded to the fabric during garment processing. After pressing and ironing, it can be tightly combined with the fabric to form a whole. The main function is to support the skeleton, making the appearance of the clothing flat, firm, and stable. It can be divided into shoulder lining, chest lining, waist lining, collar lining, etc. according to the different parts of the clothing lock. In 1995, the global consumption of non-woven clothing adhesive lining exceeded 500 million US dollars, with an annual growth rate of approximately 2%. Non woven fabrics account for 65% to 70% of various clothing linings. The products range from simple mid to low end hot melt transfer adhesive linings, powder spreading linings, powder dot linings, and pulp dot linings, to high-end adhesive linings such as double point adhesive linings, low elasticity linings, four sided linings, ultra-thin fashion linings, and color series non-woven linings. Since the application of non-woven adhesive lining in clothing, the use of adhesive instead of sewing has further propelled clothing production into the era of industrialization, improving the efficiency of garment production and increasing the diversity of clothing styles.
2 synthetic leather base fabric
The production methods of synthetic leather are divided into dry processing method and wet processing method. In dry processing method, it is further divided into direct coating method and transfer coating method according to the coating method. The direct coating method is a technique in which a coating agent is directly applied to a base fabric. This method is mainly used to produce thin synthetic leather waterproof clothing; The transfer coating method is the main production method of dry synthetic leather. It involves applying a prepared solution slurry onto release paper, drying it to form a film, then applying an adhesive and bonding it to the base fabric. After pressing and drying, the base fabric is tightly bonded to the bonding film, and then the release paper is peeled off to become patterned synthetic leather. Wet processing methods include immersion, coating and scraping, and immersion and scraping coating. Using immersion method to produce synthetic leather by impregnating with water-based latex, improving the density of the base fabric and enhancing the bending recovery of synthetic leather. Using latex for chemical bonding enhances the moisture absorption and breathability of the base fabric. In addition, using water-soluble polyurethane for impregnation results in good product quality and avoids environmental pollution issues. Wet non-woven synthetic leather is mainly used for shoemaking, luggage, and ball leather, and the strength ratio in the warp and weft directions should not be too high. The processed synthetic leather is further processed into synthetic leather through layering, grinding, surface grinding, embossing, and printing. In 2002, Japan developed a faux deer skin non-woven fabric based on ultra-fine fiber hydroentangled non-woven fabric. Due to its good breathability, moisture permeability, soft hand feel, bright color, full and uniform fuzz, and advantages such as washability, mildew resistance, and moth resistance compared to genuine leather, it has replaced a large number of genuine leather clothing products abroad and become a new favorite of fashion designers.
3 Warm materials
Non woven insulation materials are widely used in warm clothing and bedding. According to different processing methods and usage, they are divided into products such as spray bonded cotton, hot melt cotton, super imitation down cotton, and space cotton. Their fluffiness is over 30%, air content is as high as 40% to 50%, and their weight is generally 80 to 300 g/m2, with the heaviest being up to 600 g/m2. These types of thermal insulation materials are basically made of synthetic fibers (such as polyester and polypropylene) that are combed into a net and then bonded together with highly fluffy fibers using adhesives or hot melt fibers to form thermal insulation flakes. They have the characteristics of being light, warm, and wind resistant, and are widely used in ski suits, cold coats, etc. Non woven thermal flocs have been widely used in the clothing industry, replacing traditional cotton wool, down, silk wool, ostrich velvet, etc. to make cotton jackets, winter coats, ski shirts, etc. This kind of products usually use three-dimensional crimped hollow fiber as raw material, conventional polyester and polypropylene fiber as auxiliary raw materials, and then use hot-melt method or spray method to strengthen them, so as to maintain the loose structure, which is light and warm. The three dimensional hollow polyacrylate fiber or two-component fiber treated with organosilicon lotion, which is made by hot air bonding, is known as artificial down. The thermal insulation film made of far-infrared fibers not only improves the bulky appearance of the insulation material for winter clothing, but also enables the wearer to achieve comfort, warmth, beauty, and health while keeping warm and covering the body! Therefore, far-infrared cotton is a new and good thermal insulation material. Whether wet washed or dry cleaned, the thermal insulation film has almost no effect on its canopy looseness and performance, and is highly welcomed by consumers. With the development and application of various ultrafine fibers, as well as the advancement of non-woven fabric processing technology, multi-layer composite thermal insulation flocs will have good market prospects.
4 Non woven protective clothing
In modern daily life and work environments, various types of pollution, including electromagnetic waves, constantly threaten human health. With the strengthening of human self-protection awareness, the protective performance against various hazardous environments has become a new challenge in today's protective clothing market. The new type of protective clothing material must not only have protective properties, but also high requirements for softness, drape, breathability, and sometimes must be wear-resistant or reusable, and even biodegradable. Compared with protective clothing made from traditional textile fabrics, non-woven fabrics produced by various production processes interpenetrate each other, and through hybridization and compounding, many new and colorful products can be created. The combination of multiple processes makes up for the shortcomings of a single process, thus meeting different needs in different environments. For example, the use of needle punching, spunbonding, coating processes, and high-temperature resistant treatments can prevent moisture and insulation; Spunbond polypropylene, water jet chemical bonding, and melt blown ultrafine fibers can be used to defend against liquids and gases; A non-woven fabric made by uniformly mixing textile fibers and metal fibers can effectively control static electricity phenomena; The use of ultrasonic bonding and flash spinning of polyethylene nonwoven fabric and polypropylene SMS nonwoven fabric can eliminate released pollutants and bacteria. Non woven fabrics have a wide range of applications in the field of protective clothing, and can be made into flame resistant clothing, electromagnetic wave resistant clothing, chemical resistant clothing, anti-static clothing, antibacterial and dust resistant clothing, and so on. The medical clothing used to prevent and control SARS in 2003 was a composite non-woven fabric. A brand new product that combines various advantages with special craftsmanship. Non woven fabrics have been widely used in the protective clothing market due to their superior protective properties, heat dissipation, comfort, and environmental friendliness.
5 Clothing and Ready to Wear Clothing
The emergence of non-woven fabrics as ready to wear clothing is still relatively rare. With the deepening of research on new non-woven fabric technologies, some manufacturers have entered the clothing industry and competed with traditional knitted and woven fabrics. Large enterprises such as the United States and Germany have demonstrated the application ability of non-woven fabrics in the field of clothing, which is worth looking forward to in the clothing industry. The Miratec hydroentangled nonwoven fabric produced by PGI in the United States using Apex technology is a new generation of nonwoven fabric products that can replace textiles and knitwear. The introduction of new technologies has brought broad market prospects and development directions to non-woven fabrics, opening up a huge market for non-woven fabrics to enter the field of clothing and ready to wear. Miratec spunlace nonwoven fabric has outstanding strength, durability, and uniformity. It has high strength in both vertical and horizontal directions, which can have true elasticity and is not easy to tear, wear, or shrink. The overall design of the product reflects comfort and fashion. At the same time, it can be treated with spray dyeing, circular screen printing, heat transfer printing, mechanical pre shrinking finishing, and coating processing to present various colors and patterns. Its typical consumer markets are clothing, home furnishings, and car interiors. NIKE Corporation in the United States has now launched a sleeveless low neck sweatshirt made from 75% recycled polyester fiber and utilizing PGI's Apex technology several times. It also has the function of regulating temperature, indicating that non-woven fabrics are gradually entering our lives. The use of ultrasonic fusion stitching technology also provides support for the production process of non-woven fabrics as clothing materials. The world's largest non-woven fabric manufacturer, Freudenberg Nonwovens from Germany, launched a new type of spunbond filament micro denier spunbond nonwoven fabric called Evolon in February 2000. It is produced on a single assembly line that includes spinning, web formation, and hydroentanglement. This process is the company's third major technological breakthrough in non-woven fabric production. Hermann Eidel, General Manager and Chairman of Freudenberg, said that the production process of this fabric is comparable to the various processes required for woven and knitted fabrics. In addition, Evolon hydroentangled nonwoven fabric can withstand conventional water washing and has high tensile strength, tear resistance, as well as good drape and hand feel in all directions. Evolon nonwoven fabric is positioned in a wide range of durable and disposable product markets, especially in the clothing market dominated by traditional textiles, including adult and children's sportswear, casual wear, and workwear. At the 2010 Shanghai World Expo, the German Pavilion with the theme of a harmonious city actively reflected green environmental protection thinking and promoted the achievements of circular economy by starting with daily life clothing. The uniform jacket worn by the staff of the German Pavilion is a special polyester fiber non-woven fabric. Not only durable but also recyclable, and can be reused as textile fibers after processing. The white T-shirt worn by the staff in summer looks no different from ordinary cotton clothes, but it has the characteristic of rapid degradation. Once it comes into contact with the corresponding bacteria in the soil, it will be completely decomposed. Even clothing dyes and buttons do not pose any environmental hazards during the degradation process. It is reported that after the World Expo, these used T-shirts will be buried underground in the German Pavilion and degraded to provide nutrients for the trees to be planted later. In addition, the hydroentangled wool non-woven fabric developed by the New Zealand Wool Institute Non woven Group has good rebound, can withstand 30000 bending cycles without damage or breakage, can regulate heat, and can be used as an ideal sportswear fabric. It has also been developed for use as outerwear materials such as pants and jackets. In 2004, the high visibility fluorescent fabric MHV was launched by Mogul Nonwovens Company in Türkiye. The polyester spunbonded fabric has no wear and tear at the edges and is suitable for ultrasonic sewing. It can replace traditional fabrics in the clothing field. With the continuous advancement of non-woven technology and the extensive development of new non-woven fabrics, the combination of non-woven fabrics with clothing will become more and more common.
