Abstract

The invention discloses antibacterial, anti-yellowing and environment-friendly chest circumference cotton and a preparation method thereof. The antibacterial, anti-yellowing and environment-friendly chest circumference cotton is prepared from the following raw materials in parts by mass: 50-95 parts of high EO-terminated polyether polyol, 1-30 parts of high-activity polymer polyol, 1-10 parts of allyl alcohol polyoxyethylene ether, 1-2 parts of a cross-linking agent, 0.5-3 parts of a foam stabilizer, 0.5-3 parts of a composite reactive amine catalyst, 1-8 parts of a pore opening agent, 3-6 parts of a composite yellowing-resistant agent, 2-4 parts of water, 4-8 parts of traditional Chinese medicine powder, 0.5-3 parts of an anti-ultraviolet additive, 0.5-3 parts of nano-silver, 0.5-3 partsof a chitin finishing agent and 30-60 parts of modified MDI. The antibacterial, anti-yellowing and environment-friendly chest circumference cotton has the advantages that the aperture ratio is largerthan 95%, the breathability is larger than 3 cfm, and dryness and breathability are achieved; the falling ball rebound rate is greater than 55% or even 60%, and the cotton has Q-bounce property and isnot easy to deform; and the color-fastness-to-light grade and the phenol yellowing resistance grade are more than 3.5.

Description

technical field [0001] The invention relates to the technical field of bust cotton, in particular to an antibacterial, yellow-resistant and environment-friendly bust cotton and a preparation method thereof. Background technique [0002] In modern society, bras have already become an indispensable product for women's body shaping. The core material of the bra, namely the bust cotton, plays a vital role in the quality of the whole bra. At present, bra cotton on the market can be roughly divided into polyurethane foam, latex, standing cotton, and sandwich mesh. Among them, traditional polyurethane foam accounts for more than 80% of the consumption due to its lightness and high cost performance. Traditional polyurethane bust cotton uses TDI foaming, and TDI itself is a dangerous chemical, which is harmful to operators during the production process and causes air pollution; the organotin metal catalyst used in TDI foaming is also harmful to the human body. Traditional bust cot...
