Technical Field

The invention mainly relates to the technical field of textile fiber processing, in particular to a strengthening treatment method of flowering cotton.

Background

The flowering cotton is cotton produced by using old cotton fabrics, cleaning and bleaching the old cotton fabrics again, then flowering the old cotton fabrics by a flowering machine, and then drawing the cotton fabrics; along with the gradual improvement of living standard of people, the fashionable and quality requirements of clothes are higher and higher, people generally like cotton clothes, because the cotton clothes or other articles are softer and more skin-friendly, safe and healthy and can not cause skin allergy, but along with the continuous appearance of styles, the cotton old clothes are more and more, a plurality of accumulated old clothes are thrown away at any time, resources are wasted and the environment is polluted, so the waste cotton products are recovered, most of the prior waste cotton products are recovered by bleaching the waste cotton products, then a flowering machine is used for flowering, and then the cotton products are prepared into the flowering cotton through drawing, but the cotton products are the waste cotton products which are used for a period of time, and then the cotton products are washed and bleached with high strength in the recovery processing process, so that the strength of the prepared cotton for flowering is further reduced, and the use range of the flowering cotton is limited, can only be used for preparing low-grade products, so the strength of the flowering cotton needs to be improved to expand the application range of the flowering cotton.

Disclosure of Invention

In order to remedy the defects of the prior art, the invention aims to provide a method for strengthening treatment of flowering cotton.

A strengthening treatment method of flowering cotton comprises the following steps:

(1) cleaning: placing the waste cotton products into a washing powder solution, ultrasonically cleaning for 50-60 min at the temperature of 45-55 ℃ and the frequency of 28-30 kHz, washing the waste cotton products clean by using clear water, drying the waste cotton products, fully removing stains in the waste cotton products, facilitating post-treatment, and improving the whiteness of flowering cotton to obtain cleaning cotton;

(2) and (3) flowering: carrying out flowering treatment on the cleaned cotton by using a flowering machine, so that the post treatment is more sufficient and uniform, and obtaining the primary flowering cotton;

(3) primary reinforcement: soaking the primary flowering cotton in a sodium bicarbonate solution, adjusting to a vacuum state, soaking at normal temperature for 10-12 h, taking out, washing with clear water, and subjecting the flowering cotton to vacuum treatment by a low-concentration sodium bicarbonate solution to cause slight alkali shrinkage, so that the elasticity and tensile strength of the flowering cotton can be improved, the whiteness and durability of the flowering cotton are enhanced, and primary reinforced cotton is obtained;

(4) softening treatment: soaking the primary reinforced cotton in a polyethylene glycol solution at 40-50 ℃ for 3-4 h, so that the flexibility and the antistatic property of the cotton can be remarkably improved, the defect that the waste cotton is aged and hardened is overcome, the grade of the cotton is improved, the cotton is convenient to use, and the cotton is taken out and washed with clear water to obtain softened cotton;

(5) secondary strengthening: soaking softened cotton in a strengthening solution, adjusting vacuum, soaking for 5-6 h at 40-45 ℃, further improving the strength of flowering cotton, adding carboxymethyl chitosan, potassium polymetaphosphate, a nano silver solution and polyethylene imine into the strengthening solution, enabling the strengthening solution to be adsorbed on cotton fibers after vacuum soaking, improving the whiteness and antibacterial effect of the flowering cotton, enhancing the tensile strength and anti-aging performance of the cotton fibers, enabling the flowering cotton to avoid hardening and yellowing of color and luster in the long-term use process, prolonging the service life of the flowering cotton, taking out, washing with clear water, and freeze-drying until the water content is 0-8%, so as to obtain secondary strengthening cotton;

(6) drawing: the secondary strengthening cotton is subjected to wire drawing, so that the later-stage use of the blossoming cotton can be facilitated, the flexibility of the blossoming cotton is improved, the practicability is improved, and the high-strength blossoming cotton is obtained.

And (2) repeating the ultrasonic cleaning in the step (1) for 2-3 times, taking out after each ultrasonic cleaning, washing with clear water, and then placing in the washing powder solution again for ultrasonic cleaning.

And (2) drying in the step (1) at the temperature of 45-50 ℃ until the water content is 10-15%.

The sodium bicarbonate solution in the step (3) has a mass percentage concentration of 3-4%.

The volume fraction of the polyethylene glycol solution in the step (4) is 63-67%.

The strengthening liquid in the step (5) is prepared from the following raw materials in parts by weight: 31-33 parts of carboxymethyl chitosan, 24-26 parts of potassium polymetaphosphate, 18-20 parts of nano silver solution, 10-12 parts of polyethyleneimine and 350-400 parts of water.

The nano silver solution has the nano silver particle size of 35-40 nm and the nano silver content of 20-22%.

The wire drawing in the step (6) has the length of 26-32 mm and the linear density of 1.65-2.15 dtex.
