Description
Technical Field
The invention belongs to the field of non-woven fabric production and manufacturing, and particularly relates to a manufacturing method of elastic non-woven fabric, the elastic non-woven fabric and an elastic product.
Background
The non-woven fabric is formed by arranging textile short fibers or filaments in an oriented or random mode to form a fiber web structure, and then reinforcing the fiber web structure by adopting a mechanical method, a thermal bonding method or a chemical method and the like, has the characteristic of crossing multiple disciplines and technologies, has the characteristics of continuously expanding the application field of the non-woven fabric in recent years, is developed rapidly in the textile field, and is considered as a new economic growth point for the development of the future textile industry. The elastic non-woven fabric has good extensibility, so that the elastic non-woven fabric can be widely applied to the fields of clothing, household textiles, medical and health materials and the like, and is valued by various research units and enterprises. The appearance of elastic non-woven fabrics not only widens the application field of the existing non-woven fabrics, but also improves the additional value of the non-woven fabrics. For example, in the field of clothing, the elastic non-woven fabric can adapt to the movement of a human body, has the advantages of close fitting, comfort and the like, and improves the comfort and the corresponding functionality of the clothing; the fabric can be used for hair leather, shoe covers, bedspreads, quilt covers, home textile coating materials, lining materials and the like in the field of home textiles, and can meet the requirements of home textiles on the appearance or elastic function of products; in the field of industrial textiles, in particular to medical and sanitary materials, the requirements of certain medical and sanitary materials are met by the technical scheme of compounding the elastic non-woven fabric with other non-woven fabrics and the like, and the elastic non-woven fabric can be widely applied to products such as bandages, sanitary towels, paper diapers and the like. With the development of nonwoven technology, the application field of elastic nonwoven fabrics will be continuously expanded. Elastic non-woven fabrics have more products and more preparation methods, and the elastic non-woven fabrics are classified according to the processing technology of non-woven fabrics and roughly classified into three methods: short fiber carding and web forming, elastomer filament spinning and web forming, and composite processing.
The short fiber carding and web forming method is to adopt elastic fiber or high-crimp fiber to carry out carding and web forming, and then to carry out reinforcement methods such as needling, spunlace or thermal bonding, and the elastic non-woven fabric is prepared. Due to the physical properties of the elastic fibers and the mechanical characteristics of the carding machine, the elastic fibers bring certain difficulties to carding and web formation, have extremely high requirements on a carding process and card clothing, and are difficult to popularize and use in a large area, so that the elastic non-woven fabric is prepared by carding and web formation processing of crimped fibers. However, the elastic nonwoven prepared by the method has insufficient elasticity, the application of the product is limited, and excessively high crimp is easy to form neps and the like in the carding process, so that the performance of the product is influenced. Or mixing non-elastic fibers and elastic fibers, carding to form a web, and then performing elasticizing treatment to prepare the elastic non-woven fabric.
Elastomeric filament spunlaid processes include both spunbond and meltblown processes of elastomers. The thermoplastic elastomer master batch is used for melt spinning to form a net-shaped structure, so that the elastic non-woven fabric is obtained. For example, chinese patent CN1772992A discloses a method for manufacturing elastic nonwoven fabric by spunbonding and an apparatus thereof, wherein the method comprises the steps of stirring, filtering, metering, spinning, drafting, lapping and hot rolling, and the apparatus comprises a feeding system, an extruder, a filtering system, a metering pump, a spinning chamber, a drafting device, a web forming machine, a hot rolling system and a winding machine. The elastic non-woven fabric prepared by the method needs to be provided with a heating system, has high requirements on the rheological property of the elastomer master batch and has higher preparation cost. Chinese patent CN1445390A discloses a method and apparatus for manufacturing polyurethane elastic nonwoven fabric by melt-blowing web, feeding polyurethane particles into a screw extrusion mechanism, heating and melting at 180-260 ℃, extruding from a spinneret orifice of a die head, blowing hot air flow at two sides of the spinneret orifice, stretching the melt to form superfine fibers, and forming polyurethane elastic nonwoven fabric by self-adhesion. The method has the same requirements as a spunbond method on the rheological property of the polyurethane master batch, and simultaneously needs a large amount of hot air flow, so that the energy consumption is high; the elastic non-woven fabric is composed of superfine fibers, the physical and mechanical properties of the product are weak, and the application of the product is limited to a certain extent. In addition, there is also a method of preparing elastic nonwoven fabric by improving elastomer master batch or by mixing master batch and composite spinning. For example, U.S. patent No. 2009068912, "ELASTIC spun non woven AND ELASTIC non woven FABRIC composite SAME", published 3, 2009 on 12, is a method of making ELASTIC NONWOVEN FABRICs by multicomponent composite spinning.
The composite processing method is to make two or more than two kinds of nonwoven fabrics with different properties or the composite of the nonwoven fabrics and textile and plastic film products into elastic nonwoven fabrics by chemical bonding, thermal bonding, water jet or needle punching reinforcement. The composite processing method includes an embedding method and a fiber web composite method according to different composite processing modes and product structures. Embedding methods elastic web embedding methods and elastic filament embedding methods. The elastic filament adopts more spandex fibers, and the elastic net has various forms, can be woven fabric or knitted fabric. Generally, an elastic net or elastic filaments are compounded with an upper layer of non-elastic non-woven fabric and a lower layer of non-elastic non-woven fabric, the elastic net or the elastic filaments are positioned in the middle to form a sandwich structure, and the elastic non-woven fabric prepared by the method generally has unidirectional elasticity, namely, elasticity is provided in one direction, and non-elasticity is provided in the other direction. For example, chinese patent CN104647860B, discloses a "elastic nonwoven sandwich composite device and process that is stretchable in the cross direction", where the nonwoven is elastic in the cross direction, US20090047855 discloses a nonwoven laminate having elastic in the cross direction by laminating an elastic layer along at least one surface to an extensible nonwoven by means of strand spacer elements that are extensible in a first direction of the nonwoven, forming longitudinal elasticity, and being inelastic in the cross direction.
