Example Embodiment

[0015] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific embodiments.

[0016] The dyeing and finishing method of nylon spandex knitted fabric of the present invention is mainly realized by the following steps in sequence: pretreatment step A, blank setting step B, dyeing step C and finished product forming step D. For the convenience of description, the nylon spandex knitted fabric is called grey cloth.

[0017] A. Pretreatment steps

[0018] The blanks are arranged in the Taiwan Huashan washing machine, and continuous open-width relaxation washing is carried out in 1 to 6 boxes. The washing time of each box is 1.5 minutes. The parameters of the relaxation washing are shown in Table 1.

[0019] Among them, each washing temperature can be changed within the range of ±2℃, and the tension ratio and speed ratio in Table 1 correspond one-to-one. Because the grey fabric shrinks during washi...

Abstract

The invention discloses a method for dyeing and finishing nylon spandex knitted fabrics, which comprises the following steps of: A, performing pretreatment, namely washing the nylon spandex knitted fabrics continuously in a mode of open width and loosening at the temperature of 85+/-2 DEG C, 90+/-2 DEG C, 85+/-2 DEG C, 70+/-2 DEG C, 50+/-2 DEG C and 35+/-2 DEG C for 6 times and 1.5 minutes every time, and adding 5g of degreaser into each liter of first-time, second-time and three-time washing liquid respectively, wherein a tension ratio is 98.5-100.7, and a speed ratio is 20-18.6; B, performing grey cloth sizing for about 40 seconds, and adding 20 to 30g of antioxidant into each liter of padding liquid, wherein the pressure of a padder is 1 kilograms, the temperature is 198 DEG C, the speed is 15 yards, the wind power is 60Hz, and the large overfeeding is between 20 and 25 percent; and C, dyeing in a dyeing machine by a pretreatment step I, a pretreatment step II and a coloring step. The nylon spandex knitted fabrics which are dyed and finished by the method have the characteristics and styles of high strength and vertical sense, smoothness and abundant three-dimensional texture, are not wrinkled and are suitable for overclothes, so the application range is expanded greatly.

Description

technical field [0001] The invention relates to a method for dyeing and finishing fabrics, in particular to a method for dyeing and finishing nylon and spandex knitted fabrics. Background technique [0002] The existing general process of dyeing and finishing is pre-relaxation, setting, dyeing and finishing in sequence. After dyeing and finishing treatment of nylon and spandex, the fabric has poor verticality, is easy to wrinkle, does not stand up and scratches, and has a narrow application area. For a long time, nylon and spandex fabrics are usually As an underwear fabric, the scope of application has been greatly limited. Contents of the invention [0003] In view of this, the object of the present invention is to provide a method for dyeing and finishing nylon spandex knitted fabrics. After dyeing and finishing nylon spandex knitted fabrics, it can have high strength, good vertical feeling, no wrinkle, straight and scratchy, and rich three-dimensional texture. Features...
