Problems solved by technology

The traditional fiber opening treatment is generally treated under high temperature (100-110°C) alkaline conditions for 30-40min. This type of fiber opening treatment is beneficial to save processing time. It is difficult to control the degree of dissolution of the "sea" component in an alkaline environment. Once the "sea" component is completely dissolved and the "island" component is separated into ultrafine fibers, it is difficult to quickly find the end point of the fiber opening treatment or If the fiber opening treatment is terminated in time, the "island" component separated into ultrafine fibers will be more easily hydrolyzed, resulting in weight loss / weight loss of the "island" component

Embodiment 1

[0050] Embodiment 1: a kind of fiber opening method of sea-island fiber textile, comprises the steps:

[0051] Step 1, according to the amount in Table 1, each component is formed to cooperate with each other to make a padding solution;

[0052] Step 2, the sea-island fiber textile (the content of "sea" component and "island" component, whether the textile is pure sea-island fiber is shown in Table 2) is immersed in the padding solution, and the strip as shown in Table 1 The island-in-the-sea fiber textiles of the liquid rate are rolled to form a cloth roll, and the outside of the cloth roll is coated with a plastic film, and the cloth roll is rotated around the axis line of the cloth roll at the speed in Table 3, and the cloth coil is disclosed in Table 3. The rotational speed of the axis line, the stacking temperature and the corresponding time;

[0053] Step 3: Remove the plastic film, take out and unwind the stacked cloth rolls, and wash them on the open-width continuous ...

Abstract

The invention discloses a fiber opening method for sea-island fiber textiles, which comprises step 1, preparing a padding liquid; step 2, immersing sea-island fiber textiles in the padding liquid, and rolling the textiles with a liquid-carrying rate of 80-100% Form a cloth roll, and wrap a flexible hydrophobic layer on the outside of the cloth roll, and stack it for 6-22 hours at a temperature of 30-40°C; step 3, remove the flexible hydrophobic layer, and place the stacked cloth Coiling, unwinding, washing, and drying; the padding liquid in step 1 includes the following components in weight percentage: NaOH is 3-8%; accelerator is 1.0-2.0%; scouring agent is 1.0-2.0%; The balance is water. Due to the high-efficiency and low bath ratio processing method of the present invention due to the cold stack fiber opening and open-width vibration cleaning, the fiber opening effect is mild and easy to control. It has the advantages of not easy to appear colored flowers and stains, and adopting this treatment method can also achieve the purpose of "water saving, energy saving, and emission reduction", which is beneficial to environmental protection.

Description

technical field [0001] The invention relates to the field of functional finishing methods of textiles, more specifically, it relates to a fiber opening method of sea-island fiber textiles. Background technique [0002] Sea-island fibers, also known as hyperconjugated fibers, are composed of a core component (also known as "island" phase or dispersed phase) composed of a polymer material dispersed in a sea group composed of another polymer material in a longitudinally continuous form. Partition (also known as "sea" phase or continuous phase). [0003] The island-in-the-sea fiber uses two polymers with different solubility properties as spinning raw materials for composite spinning, in which the polymer with good solubility is used as the "sea", and the other polymer is used as the "island". The cross section of the obtained fiber is a sea-island structure in which the skin layer of the sea component surrounds the core layer of the island component. The island-in-the-sea fib...
