Problems solved by technology

However, no matter which technology is used, it has not been fully recognized by consumers at present. The most common deficiency is that after washing, there are many problems in terms of hand feeling, shape stability, shrink resistance, etc.: because The emergence of problems such as thread separation, fluffing, and pilling lead to the coarse hardening of the fabric; in terms of hydrophobicity, after some waterproof and oil-proof treatments, it also has a great negative impact on the pulling degree of organic fiber structures.
[0006] In order to improve the waterproof performance of organic fiber structures, some methods such as reconciling the processing agent and increasing the amount of coating have appeared. The resin is used to coat a thin film on the surface of the organic fiber to achieve the waterproof effect, but its durability is relatively poor.
Because it is processed by resin coating, it also has many disadvantages in terms of feel, cost, hygiene, etc.
Moreover, in order to improve the waterproof performance, a large amount of static electricity will appear, which also promotes the ability to absorb dust, garbage and other substances, making people less pleasant to wear.
What's more serious is that due to the use of toxic agents and resins, it has brought potential safety hazards and environmental pollution problems.

Embodiment 1

[0077] 100% silk dyed with acid dyes, EC / 72 counts, using the "exhaust in bath method". Water 360L in the dyeing machine, concentration 10% 2,6-dichloro-4-(3-sulfonic acid group)-S-triazine aqueous solution 3.6kg, acetic acid (4.8% concentration) 170g, sorbitol 360g, Adjust the liquid with the above raw materials. After that, the speed does not exceed 2°C per minute until the temperature rises to 50°C, and the machine runs for 20 minutes in this state. After that, the standard is not to exceed 2°C per minute, and it has been raised to 85°C. In this state, after 30 minutes of machine operation, the water is drained. Then wash with 85°C hot water for 10 minutes to make it hydrophobic. Wash again with ordinary water, and after dehydration, use 120°C dry heat to carry out the first stage of substantial drying process. Afterwards, mix 100L solution with hydrophobic function, calculate according to the water absorption rate of 70%, dehydrate the cloth after absorbing the correspo...

Embodiment 2

[0081] 100% cotton of navy blue 60 / 22 / 2 counts dyed with chlorotriazine reactive dyes, the cloth with a total weight of 24kg is injected with 360L of water in the dyeing machine, and dropped into 10% sodium chloride aqueous solution (o.w.f20%) 4.8 kg and 9kg of sodium bicarbonate, 1.8kg of sodium carbonate, 10.8kg of sodium sulfate, and 480 pieces of hydrolyzed silk components (o.w.f 2%). Put the above raw materials into water below 30°C for stirring. Gradually raise the temperature to 50°C at a speed exceeding 2°C, and run the machine for 20 minutes while maintaining this temperature. Gradually heat up to 85°C at a rate of no more than 2°C per minute. At this temperature, run for 30 minutes to drain water, then wash with hot water at 85°C. After the hydrophobic process, wash with water again, and after dehydration, Substantial drying treatment was carried out at a temperature of 120°C, and then, as the last process, a high-temperature heat treatment at 170°C was carried out a...

Abstract

The invention provides a method for improving the organic fiber material and imposing hydrophobic property, wherein, it immerges organic fiber material into the solution of dihalogen triazine compound, hydroxyl alcohol and hydroxyl compound which has hydrophilic group substitute, to treat the organic fiber material with heating method and bath adsorption method at 30-90Deg. C in thermal conditionand 120-180Deg. C for drying, while the dihalogen triazine compound is formula (1). The invention uses aforementioned solution to impose stable property and anti-soil property into the organic fiber material.

Description

technical field [0001] The invention belongs to the technical field of production of organic fiber structures, such as wool, cotton, silk, hemp, nylon, etc., and specifically relates to a method for improving the wearing comfort and hydrophobicity of organic fiber structures. Background technique [0002] In terms of the feel and moisture absorption of fabrics, organic fiber structures such as natural fibers, recycled fibers, and nylon are very good raw materials. [0003] Compared with synthetic fibers, because the organic fiber structure contains a large amount of hydrophilic NH 2 Therefore, when washing, the fabric absorbs a large amount of water and swells up, causing friction between the fabrics, causing a series of splitting, fluffing, pilling, etc., which makes the fabric hard; and , Through the drying process, the organic fiber structure not only causes shrinkage, but also is inferior to synthetic fibers in terms of rigidity, flexibility, shrink resistance and other...
