Embodiment 1

[0016] Embodiment one: a kind of open-width desizing process of MFPET fiber dyeing

[0017] A kind of open-width desizing process of MFPET fiber dyeing, the open-width desizing auxiliary agent that described open-width desizing process uses contains following material per liter:

[0018] Liquid caustic soda 25 grams;

[0019] Emulsified dispersion desizing agent M 1.5 grams;

[0020] Sodium tripolyphosphate 2 grams;

[0021] Degreaser F 2 grams.

[0022] The temperature condition of the open-width desizing process is 98°C.

[0023] The vehicle speed of the open-width desizing process is 40 / min.

[0024] The liquid caustic soda is selected from the currently commonly used liquid caustic soda with a mass concentration of 30-32% or with a mass concentration of 40-42%.

Abstract

The invention discloses a full width desizing technology of MFPET stock dying. Full width desizing auxiliaries adopted by the full width desizing technology are prepared from 20-30 g of liquid caustic soda, 1-2 g of emulsification dispersion desizing agent, 1.8-2.2 g of sodium tripolyphosphate and 1.8-2.2 g of a degreaser. The full width desizing technology is good in treatment effect and convenient to implement.

Description

technical field [0001] The invention relates to an open-width desizing process for MFPET fiber dyeing, which belongs to the technical field of textile printing and dyeing. Background technique [0002] MFPET is a new type of organic polymer aromatic polyester product belonging to the same polymer series as PET and PBT. The crystallinity of MFPET polymer is smaller than that of PET, so it has some advantages that PET fiber does not have, such as good elasticity, softness, and easy dyeing; the structure of MFPET fiber itself can endow the fabric with good elasticity, and the elastic elongation is much higher. in PET fibers. [0003] MFPET is a new type of modified polyester product, MFPET has excellent characteristics. In the field of chemical applications, MFPET fiber combines the good elasticity, wear resistance and fatigue resistance of nylon; the excellent bulkiness, softness and color fastness of acrylic; and the good wrinkle resistance, dimensional stability and heat r...
