The invention relates to a using method of an anti-pilling agent for spinning, which comprises the following steps:
the invention discloses an anti-pilling agent for textile on polyester knitted fabric, which adopts a one-bath one-step padding process:
the dosage is as follows: 20-40 g/L of anti-pilling agent
The process comprises the following steps: padding the anti-pilling agent working solution (the pressure is 2Kgf/cm2, the vehicle speed is 50rpm) → shaping the solution at 160-170 ℃ for 80S; the anti-pilling performance is judged to be 1-5 grade, and 5 grade is optimal.
The application test results are as follows:
the main component of the product is special high molecular polymer emulsion, the main chain of the polymer is provided with active groups, and the active groups have multifunctionality and extremely strong activity and can be self-crosslinked; or can be bonded with active groups on the fiber to form a net-shaped transparent film with friction resistance, water washing resistance and sunlight resistance on the surface of the fabric. The function of a polymer in a cross-linking film on the surface of the fiber is utilized, so that the surface of the fiber is coated with a layer of wear-resistant polymer film, the slippage of the fiber is weakened, and the fluffing and pilling tendency is reduced; meanwhile, the polymer is uniformly cross-linked and bonded on the surface layer of the yarn, so that the fiber tips are adhered to the yarn, and the yarn is not easy to fluff and pill during friction. In the finishing process of the fabric, the fabric has excellent film forming property and permeability, so that the fabric can permeate into the fiber while forming a film on the surface of the fabric, and the fiber and the plush are bonded in a cross-linking way to form a net-shaped film structure, thereby having good anti-fluffing and anti-pilling effects.
The use of cationic emulsifiers in the present invention, rather than anionic emulsifiers commonly used in the prior art, allows for their use with other cationic finishes (in one bath) without the anions of the prior art being readily neutralized with other cations. In production, the anti-pilling agent in the prior art must be used alone and cannot be used together with finishing agents related to other processes, such as a hand feeling agent (a softening agent), a color fixing agent and the like, so that a plurality of process steps are required in cloth processing. The invention has no reaction problem, thereby reducing the process flow in the cloth processing, reducing the energy consumption and improving the printing and dyeing efficiency.
The polyvinylpyrrolidone added in the invention accounts for 1 to 3 mass percent of all raw materials, so that the anti-pilling agent has better film forming property and scratch resistance; the polyvinylpyrrolidone is a high molecular polymer, is soluble in water, has good film forming, dispersing, thickening, bonding and scraping resistance, has a synergistic effect after being mixed with the acrylate emulsion, and improves the anti-pilling effect of the product.
The above embodiments are merely illustrative of the technical concept and features of the present invention, and the present invention is not limited thereto, and any equivalent changes or modifications made according to the spirit of the present invention should be included in the scope of the present invention.
