According to a conventional man-made fiber Dingence (Chinese translation: Tencel) is a new man-made fiber manufactured by spinning engineering using cellulose as a raw material, because Tencel fiber uses amine oxide (nmm〇) as a solvent. The solvent can be almost completely recovered, and there is no pollution problem, and the waste can be simply burned or not decomposed. Because of the demand of the base and the %, the Tence丨 fiber can be widely used; the Tence丨 fiber is better than the general fiber and the Ten cel fiber has the microfibrillation property, so that the tree can be obtained. The right to make its products have better comfort. Therefore, Yanhai-$/τ φ material can be expected to be used in high-grade clothing, baby clothes, due to good characteristics, so the future use should be very extensive. However, TenCe 丨 fiber also has its shortcomings, that is, it belongs to the 维 纤维 fiber, its main components are C, H, 〇 three elements, because b rence 丨 fiber is not flame resistant, so in the general environment, In this case, the phenomenon of burning a fire in a fire is a potential crisis in use. 1342907 In order to avoid the occurrence of fire and igniting when wearing Tencel fiber, especially for the use of children's clothing, the fireproof manufacturing of Tencel fabric is an important issue, and the study of the fire and fire resistance The method should also be based on environmental protection, which is a good method of anti-combustion processing. This is an extremely research topic for the existing industry. SUMMARY OF THE INVENTION The main object of the present invention is to provide an improved flame retardant effect of Tencel fabric, and also improve the antibacterial property of the fabric. After the environmental protection processing procedure, it is non-toxic to the human body, but still retains the original Tencel. Soft and comfortable for the purpose. In order to achieve the above object, the present invention can be achieved in the following manner: A substance called chitin (chitin) is widely distributed on the earth, and is present in cells of lower plant fungi and algae. The cell rafts of higher plants, as well as the arthropods, the skeleton of squid, the outer shell of insects, etc.; in the industry, the shells of shrimp and crab are generally used as raw materials to make chitin. The chitin loses the acetamidine group after deacetylation, and generates chitin (c h i t 〇 s a η ). Chitin (chiti η) and chitosan (chitosa η) are natural non-toxic polymers and are biodegradable. Their structure is similar to cellulose, from 1 000-3000 4 'Glucosamine ) N- G-glucosamine (N-Acetyl and Glucosamine) is a linear polysaccharide polymer composed of stone-丨, 4-bonded structure. Its structure is similar to that of cellulose. The acetamino group (-NHC Ο C Η 3) or the amine group (-N Η 2) attached to the C-2 position. Chitin is insoluble in water but soluble in organic acids and inorganic acids. The brewing is soluble in adipic acid, formic acid, acetic acid, propionic acid, lactic acid, malic acid, succinic acid and other organic acids. Generally, chitosan with a degree of acetylene above 75% is very soluble in dilute acetic acid (acetic acid). Among them, chitosan has strong film-forming properties and is similar in chemical structure to cellulose. They have good adsorption and compatibility. The hydroxyl groups of chitosan, a part of amine groups and cellulose hydroxyl groups form numerous Intermolecular hydrogen bonding, and the solvent dilute acid of chitosan can also serve as a crosslinking agent for both. Therefore, 'the solution of adding chitosan (C hit 〇sa η ) is used for the processing of the Tencel fabric after soaking, and the effect of achieving the flame retardant is an excellent method. The present invention utilizes A series of processes 'developing this technology to make the existing Tence] artificial fabric 'processed into a soft, comfortable 'safe (anti-combustible), anti-, environmentally friendly clothing technology. [Embodiment] To make your review board The contents of the present invention can be clearly understood, and the following description will be made with the following description, and the following will be described. The flame-retardant processing method of the fabric of the present invention includes at least: 342907
(1) The Tencel fabric is washed and dried first. D (2) The first flame retardant processing procedure is based on low molecular weight chitosan (Chitosan, lowmolecular) ALDRICH, especially 〇·ι% ~1% Chhosan solution. Increase the concentration 〇·丨 each time. /. The solution was immersed in the Ten cel fabric for about 20 minutes, and then pressed by a press (2dip-2nip method, the pressure ratio was about 90%), and pre-dried at 1200 ° C for 5 minutes.
(3) The second flame retardant processing procedure, and then the last step of the Tencel fabric is again amine-based acid salt (A rn ηι ο niumamid 〇su 1 fate) NH4〇S02NH2, SHOWA, (with 5~30% concentration For Fan Tianshou, but especially 20% amm ο niumsu 1 famate is the best) ' Urea NH2CONH2 (5~30% concentration is the standard * life, but especially 20% urea is the best) formula Mix the solution, soak for about 20 minutes, then press it with a press (2dip-2nip), pre-dry at 120 °C *5 minutes, then dry at 1 60 0: * 5 minutes Curing processing.
(4) Cleaning and drying: According to the CNS 8 1 48 textile clothing labeling method, the ratio of the sample to the washing liquid is 1: 30, and the liquid temperature is 4 〇. C Add 2 g of synthetic detergent per liter of water, wash for 5 minutes, rinse with water for 2 minutes, then dehydrate and dry.
Among them, the second flame-retardant processing procedure in the above step (3) can still add 'hydrogen phosphate diamine solution (2%) to the original 20% amm ο niumsu 丨famate, 20% urea solution. DAP 342907 (diammonium hydrogen phosphate) (ΝΗ4) 2ΗΡ〇4 As a flame retardant additive, it is subjected to the original soaking treatment for more than 20 minutes, and is sucked by a pressure suction machine (in 2 dip - 2 ni ρ mode, the pressure absorption rate) About 90%), after pre-drying treatment at 1 20 ° C * 5 minutes, the treatment is carried out at 1 60 ° C * 5 minutes for cu ι · ing, and the effect is also good. The fireproof processing theory achieved by the invention processed on Tencel fiber is .
The Tencel fiber is treated with sulfamate as a flame retardant process for sulfation, and the following reaction formula can be formed:
Cell-OH +NH2-S020H II CdOSO, NH4 and hydrogen phytide are reacted as follows: (NH4)2HP〇4 a nh3 + nh4h2po4 Δ (ΝΗ4)2ΗΡ〇4 — νη3 + η3ρο4 Δ
It can be seen from the above formula that the decomposition of hydrogen phosphate diamine produces Ν3 gas, which can dilute the concentration of flammable gas to prevent flame flame. When the cellulose fibers are subjected to heat treatment at different temperatures after being processed by the flame retardant of the present invention, the reaction as shown in Fig. 1 is initiated, and the flame retardant is carbonized at a relatively low temperature, and the temperature is about 200 ° C ( T!), but the processing agent that produces carbonization at this temperature is limited to the phosphorus-nitrogen series of flame retardants. At higher temperatures (25 0-300 C), volatile substances are formed (deuterated to CO at the lower 3 and C〇2 at τ5), and more than 400'C carbon is deuterated to CO (τ6) and C〇2 (T7). After the fabric treated by the present invention and the fabric without the invention, the following data will be obtained: Please refer to Fig. 2 for the TGA analysis of the Tens 1 fabric after the flame retardant processing method of the present invention. Figure, where curve A is the thermal weight loss (τ g A) curve of the untreated Ten s fabric; and curve B is the thermal weight loss of the Tencel fabric treated with 20% amine sulfonate and 20% urea (TGA) curve.
