Description

Technical Field

[0001] The utility model relates to the technical field of textiles, in particular to a high-elastic composite waterproof nylon yarn. Background Art

[0002] The scientific name of nylon is polyamide fiber, which is called nylon internationally. Nylon silk is a fiber made of polyamide, which is divided into nylon filament and staple. Nylon filament can be made into stretch yarn, and staple can be blended with cotton and acrylic to improve its strength and elasticity. Nylon silk has a very wide range of applications, and the most common in daily life is in clothing and decorations. Nylon fiber is mainly filament, and nylon has the best wear resistance among commonly used fibers. It is widely used in the production of deformed silk. However, the waterproofness and fire resistance of deformed silk made of nylon are poor, and after the deformed silk made of nylon is used for a period of time, its elasticity and toughness are greatly reduced, affecting the normal use of the product. In view of this, the inventor proposes a high-elastic composite waterproof nylon silk, which is made of nylon silk and stretch yarn by blending and then compounding waterproof and fireproof materials, so that the nylon silk has elasticity and can be waterproof and fireproof, and improves applicability and practicality.

[0003] In order to improve the waterproof performance and stability of nylon yarn, a Chinese patent (authorization announcement number: CN207875039U) discloses a composite nylon warp and weft homogeneous fabric. The utility model includes a homogeneous fabric body, which is provided with a waterproof and breathable layer, a first natural material fabric layer, a metal wire mesh layer, a thermal insulation layer and a second natural material fabric layer from top to bottom. The metal wire mesh layer includes warp, weft and metal fine wires. The first natural material fabric layer and the second natural material fabric layer both include a nylon yarn body, and the nylon yarn body includes a nylon layer and a core layer. The nylon layer is coated on the outside of the core layer. The utility model has waterproof and breathable properties, and has thermal insulation functions, and is antibacterial, which improves adaptability.

[0004] This solution still has some shortcomings in application. After the deformed yarn made of nylon is used for a period of time, its elasticity and toughness are greatly reduced. When it is pulled, it is easy to tear, which will affect its service life. At the same time, the fabrics woven with nylon yarn are widely used. In addition to having waterproof properties, they also need to have good fire resistance to improve their adaptability and practicality. Therefore, it is necessary to improve the structure of nylon yarn so that it has good waterproof and fireproof effects, while also having high elastic properties to improve the practicality of nylon yarn.
