Embodiment Construction

[0019] The following is attached figure 1 , 2 The specific embodiment of the present invention is described in further detail

[0020] A manufacturing process of spandex silk webbing, comprising the following steps:

[0021] (1) Material selection, choose spandex yarn as the warp yarn of the ribbon, polyester yarn or nylon yarn as the weft yarn of the ribbon, the elastic elongation of the spandex yarn can reach 6-7 times, and the elastic recovery rate can reach 95%-98%. Accounting for 20%, polyester yarn or nylon yarn accounting for 80%, the F number of polyester yarn or nylon yarn is 150 ~ 180dtex / 48F; use electronic tension measurement to ensure consistent tension during warping process, and the package size of spandex yarn is consistent , The ribbon conveying speed is controlled at 35-40m / min.

[0022] (2) warping, the warp yarns on several first drums are wound onto one or more second drums by a yarn drawing machine, and the second drum segments are arranged to wind a wa...

Abstract

The invention discloses a manufacturing process of a polyurethane filament knitted belt. Polyurethane filaments are selected to be used as warp yarns; polyester filaments or nylon filaments are used as weft yarns; and a plurality of warp yarns and a plurality of weft yarns are interwoven and connected on a knitting machine. By aiming at the use characteristics and requirements of a flat elastic belt knitted by the polyurethane filaments, according to production practice, ironing is directly performed after knitting of the polyurethane filament knitted belt is completed. The polyurethane filament knitted belt is shaped, the knitted belt deformation is prevented, and the problem that the deformation of the polyurethane filament knitted belt or the dimension nonuniformity of the polyurethanefilament knitted belt can be caused by conventional subsequent ironing is solved.

Description

technical field [0001] The invention relates to a textile production process, in particular to a production process of a spandex silk ribbon. Background technique [0002] Elastic band is a commonly used important auxiliary material for underwear and other clothing. Because the knitted elastic band has the characteristics of convenient use and comfortable wearing, it has gradually become the mainstream product of consumption. In recent years, spandex yarn has been favored by the market because of its elongation rate of 500% to 800%, elastic recovery rate of more than 95%, and better resilience and softness. Many places have replaced spandex yarn in the manufacture of knitted flat elastic products, and the market share is also expanding year by year. Spandex yarn is generally used in combination with polyester yarn or nylon yarn. Because the elasticity of these two yarns is very different, it will inevitably lead to more difficulties in the production process, especially af...
