Embodiment Construction

[0012] A kind of dust-absorbing and shrink-resistant velvet fiber, made of the following raw materials in parts by weight: soybean fiber 24, Australian cashmere 20, coconut charcoal fiber 13, chitosan fiber 11, nano-silica 2.1, alumina sol 3, N, N dimethylcyclohexylamine 1.2, lily juice 7, tetraethoxysilane 6, vermiculite 2, methacrylamide 7.2, ammonium persulfate 0.3, butylmethylimidazole chloride 170, appropriate amount of water.

[0013] The preparation method of the described a kind of anti-shrinkage anti-dust velvet fiber, comprises the following steps:

[0014] (1) Put the vermiculite in a mixed solution of concentrated sulfuric acid and concentrated nitric acid with a volume ratio of 3:1, reflux at 100°C for 4 hours, cool, filter with suction, wash until neutral, and then dry it in a vacuum oven at 100°C Internal drying for 2 hours, ultrafine grinding to obtain acid oxidation treated vermiculite powder;

[0015] (2) After drying soybean fiber, Australian cashmere, coco...

Abstract

The invention discloses an anti-shrink velvet fiber capable of preventing dust absorption. A chitosan fiber is creatively blended with a soybean fiber, Australia cashmere and the like, so that chitosan is uniformly distributed, is difficult to fall and can permeate into a cell body to be adsorbed so as to disorder the normal physiological activity of a cell and thus kill bacteria; the added vermiculite is oxidized and modified by mixed acid so as to generate a carboxy group and a hydroxyl group, so that the anti-shrink velvet fiber has favorable dispersibility and stability; furthermore, the prepared cashmere crude fiber is subjected to surface grafting modification by taking methacrylamide as a grafted monomer, irregular graft product sediment particles exist between fibers, the surface scale expansion of the fibers is restricted, the interfibrous oriented friction is reduced, the velvet felting property is improved to a certain extent, and the manufactured velvet fiber is high in breaking strength and excellent in dust absorption prevention and anti-shrink property.

Description

technical field [0001] The invention relates to the technical field of non-woven materials, in particular to a dust-absorbing and shrink-resistant velvet fiber and a manufacturing method thereof. Background technique [0002] With the continuous improvement of people's living standards, the quality requirements for textiles are also increasing. Velvet has the characteristics of thick fabrics, no deformation, no pilling, no fading, comfortable wool, delicate, comfortable, and skin-friendly. Deeply loved by people, velvet is one of the traditional Chinese fabrics because of the name of the silk fabric in which the velvet warps form loops or fluff on the surface of the fabric. Now the velvet fibers on the market are easy to absorb dust and are relatively thick when used, which is inconvenient to carry and use. Contents of the invention [0003] The purpose of the present invention is to provide a dust-absorbing and shrink-resistant velvet fiber and a manufacturing method ther...
