Problems solved by technology

[0004] The purpose of the present invention is to solve the traditional pretreatment in the prior art that uses caustic soda and other highly corrosive materials for bleaching, which is easy to cause damage to the yarn, and the traditional pretreatment process makes the yarn poor in moisture absorption or wettability , resulting in poor adhesion between yarn and dye, and the disadvantage that dye is easy to separate from yarn, and a low-temperature pretreatment process for cheese is proposed

Embodiment 1

[0037] Such as figure 1 As shown, a cheese low temperature pretreatment process specifically comprises the following steps:

[0038] S1: Washing in the initial flow: first wash the yarn with running water;

[0039] S2: Bleaching: Add sodium borate into the bleaching tank, put the yarn into the bleaching tank for bleaching;

[0040] S3: Neutralization: neutralize the bleached yarn inside the neutralization pool that puts the acidic solution into it;

[0041] S4: washing with running water again: washing the neutralized yarn with running water;

[0042] S5: drying: drying by pressing rollers and dryers;

[0043] S6: Oxidation treatment: Control the pressure inside the oxidation device to 60-80Pa, and then perform low-temperature oxidation treatment on the yarn through the oxidation device.

[0044] Further, in S1 and S4, the water temperature is controlled at 60-70 degrees Celsius.

[0045] Further, in S2, control the concentration of sodium borate in the bleaching tank at ...

Abstract

The invention discloses a cheese low-temperature pretreatment process. The cheese low-temperature pretreatment process comprises primary flow washing, bleaching, neutralization, secondary flow washing, drying and oxidation treatment. Through primary flow washing, bleaching, neutralization, secondary flow washing, drying and oxidation treatment, the cheese low-temperature pretreatment process can greatly improve yarn cleanthreadss, effectively reduce yarn damage, greatly improve yarn hygroscopicity or wettability, increase adhesiveness between yarns and dyes and facilitate subsequent dyeing.

Description

technical field [0001] The invention relates to the technical field of cheese processing, in particular to a low-temperature pre-treatment process for cheese. Background technique [0002] Package yarn is the output product of the winding process of the spinning mill in the textile industry. It is the bobbin that falls from the spinning frame or twisting machine in the previous process. According to the requirements of the subsequent process, the length of the yarn is lengthened and the defects and impurities on the yarn are removed. On the winding machine, it is rewound into a borderless or bordered yarn through a grooved drum or a rapidly reciprocating yarn guide hook, and wound into a certain shape ( Such as conical, there are also cylindrical) and a certain winding density of large-volume package yarn, usually called "cheese yarn"; size - such as a diameter of about ∮ 250mm, a height of about 150mm, different specifications, no requirements Splices (air-spliced) or smal...
