Problems solved by technology

[0004] To solve this problem, a presetting device is needed, but the existing device has technical defects. When the fabric is passed through water, the temperature of the water cannot be well controlled, which affects the quality of the product, and the effect of presetting is affected by many factors. Interference is not ideal

Abstract

The invention relates to the technical field of polyurethane material production, and discloses a pre-setting device for low-temperature stability-maintaining polyurethane filament. The device comprises a water passing tank; guide wheels movably sleeve two sides of an inner cavity of the water passing tank; a polyurethane filament body is movably connected to the outer sides of the guide wheels; a moving opening is formed in the upper part of the rear side of the water passing tank; a first motor movably sleeves an inner cavity of the moving opening; and a moving block is fixedly mounted on the rear side of the water passing tank. According to the pre-setting device for the low-temperature stability-maintaining polyurethane filament, a heater is arranged in the inner cavity of the water passing tank, so that water in the inner cavity of the water passing tank is conveniently heated; and a screw rod is driven to rotate through the moving block as a driver, the first motor is conveniently driven to move along the interior of the inner cavity of the moving opening due to the fact that the screw rod is in meshed connection with the first motor, and a connecting strip and an inclined plate are driven to move in the inner cavity of the water passing tank, so that the water in the water passing tank can be uniform in temperature, and the water passing efficiency of the polyurethane filament body is not affected.

Description

technical field [0001] The invention relates to the technical field of spandex fabric production, in particular to a presetting device for maintaining the stability of spandex yarn at low temperature. Background technique [0002] The full name of spandex fiber is the abbreviation of polyurethane fiber, which is polymerized by PTMEG and MDI. It is a modern garment industrial material, clothing fabric, spandex filament coated with short fiber yarn, that is, spandex core-spun yarn, and the elastic fabric woven with it is comfortable, fit and elastic, and has the reputation of the second skin of the human body. [0003] For knitted fabrics containing spandex, the spandex inside the fiber has a certain internal stress formed during weaving after it is off the machine. Therefore, the purpose of preheating and setting is to eliminate stress through the process of fabric sheeting and relaxation, make the size of fabric fully stable, and eliminate permanent creases in fabric in pos...
