Description
Technical Field
The invention belongs to the technical field of wool, and particularly relates to a method for preparing anti-pilling wool.
Background
Wool is a natural protein fiber with complex structure, and mainly comprises a scale layer, a cortex layer and a medulla layer, wherein cells in each layer are bonded by cell membrane composites among structures of each layer.
The scale layer is formed by overlapping flat scale cells on the surface of the fiber along the direction from the root to the tip of the fiber, and the scale layer only accounts for 10 percent of the total weight of the wool fiber, but the existence of the scale layer has great influence on the chemical and physical properties of the wool fiber. The surface of the outer skin layer of the flake is covered with a layer of tidily and compactly arranged lipoid substance, and the outer skin layer is composed of keratinized protein, so that the wool has good hydrophobicity and chemical inertness, and has the function of protecting the inside of the wool fiber from chemical substances. However, the scale structure and the pseudo-prismatic ridges on the surface of the scale layer enable wool fibers to generate a directional friction effect, the wool fibers gradually move towards the root end under the action of external force due to the existence of the directional friction effect of the scale, so that the fabric gradually contracts tightly, interweaving felting is realized, the directional friction effect also enables the tail ends of the fibers to have a tendency to slide outwards all the time, the tail ends of the slipped fibers cause fuzzing of the wool fabric, the fuzzing and the mutual entanglement of the fuzzing are gradually realized, the felting phenomenon, the itching feeling, the fuzzing and the fuzzing problems in the wearing process are generated, and the like, so that the wearability of wool clothing is limited to a great extent.
In addition, the mass of wool fibers is mostly composed of a leather layer, which is an important part affecting the physical and mechanical properties of wool fibers. The medullary layer has loose structure, is filled with air, and has the characteristics of crisp structure and low strength. The cell membrane complex occupies a small proportion of wool fibers, but can influence the effects of water and chemical agents on wool fibers to a certain extent. .
In recent years, the requirements of consumers on wool fabrics are continuously improved, and higher requirements are put on the performances of wool fabric, such as fuzzing and pilling resistance, fulling property, crease resistance, post-washing flatness and the like. At present, in addition to factors affecting the fulling property and fuzzing and pilling property of fabrics, such as fiber performance, spinning technology, yarn structure and fabric organization structure, in recent years, textile technicians focus on the scale layer of wool fibers, and the effect of reducing the scale layer of the wool fibers from pilling is achieved by adding amino silicone oil or resin anti-pilling agent and increasing lubrication.
For example, chinese patent application No. CN201710510701.3 discloses a wool fabric anti-pilling finishing agent comprising, in parts by weight: 40-50 parts of anti-pilling agent, 10-30 parts of softener, 4-6 parts of amino acid powder, 2-4 parts of tea saponin, 3-5 parts of thickener, 1-3 parts of anti-wrinkle agent, 3-5 parts of polyethylene glycol, 0.1-0.3 part of methyl palmitate, 0.1-0.3 part of defoamer and 80-100 parts of water, wherein the softener comprises amino silicone oil.
For example, chinese patent application No. CN200610086273.8 discloses an anti-pilling process for wool fiber products, wherein the anti-pilling treatment is performed in a treatment bath, the amount of anti-pilling agent is 2-6% by weight of the wool fiber products, the pH of the treatment bath is adjusted to 8.2-8.5, the temperature of the treatment bath is 25-30 ℃, the treatment time is 25-30min, and the anti-pilling agent is an aqueous emulsion containing polyacrylate resin.
However, wool treated with the amino silicone oil or resin and anti-pilling agent of the above prior art is deformed after washing with water many times. Thus, the method is applicable to a variety of applications. There is a need to develop a method for preparing anti-pilling wool which has excellent anti-pilling effect, dimensional stability after washing and appearance stability after washing.
Disclosure of Invention
The invention aims to: in order to overcome the defects, the invention aims to provide the method for preparing the anti-pilling wool, which has reasonable step design, adopts the soaping agent to remove impurities such as grease on the wool surface, then hydrolyzes peptide bonds on the surface of wool fibers through the combined effect of pretreatment and biological modification treatment, peels off scales on the surface of the wool fibers, has small damage to the wool fibers and better modification effect, and the prepared anti-pilling wool has excellent anti-pilling effect, dimensional stability after washing and appearance stability after washing, has great application value and has wide prospect.
The invention aims at realizing the following technical scheme:
a method of making anti-pilling wool comprising the steps of:
s1: placing wool into a dye vat, then sequentially adding water and soaping agent for cleaning, and preserving heat for 20-40min at the temperature of 30-50 ℃ to obtain first treated wool;
s2: pretreating the first treated wool to obtain second treated wool;
s3: placing the second treated wool into a dye vat, sequentially adding water, an organic phosphine compound, a stabilizer and ferment for biological modification treatment, preserving heat for 10-20min at the temperature of 30-50 ℃, and preserving heat for 20-40min after the temperature is raised to 40-60 ℃ at the heating rate of 0.5-1.0 ℃/min to obtain third treated wool;
s4: adding hydrogen peroxide into the dye vat of the third treated wool, and preserving heat for 10-20min at the temperature of 40-60 ℃ to obtain fourth treated wool;
