Embodiment 1

[0042] First select silk staple fiber raw materials, and select them in different categories according to different raw material sources. The main purpose is to remove impurities, stolen goods, oil stains, and separate silk raw materials of different colors. Then carry out silk pretreatment: open the finished silk raw materials on the opener equipped with rollers and cylinders, further shake off the dust and sundries adhering to the silk, and make the length of the silk fibers consistent, which is convenient Disposition of the next process.

[0043] Evenly spraying concentration is 1.5% amino, hydroxyl organosilicon emulsion (softening agent) on the short silk fiber after opening and let stand for 24 hours.

[0044] Comb the silk after standing still with a 186 comber, mainly to achieve that the silk does not contain thread and sundries, so that the length of the fiber is between 1.5cm-2.5cm. Then use synthetic detergent-alkali method for silk refining:

[0045] (a) Process ...

Embodiment 2

[0066] The silk head purchased from the silk textile factory is first opened twice on an opener with steel nails, and then layered and evenly sprayed with 1.5% softener and left to stand for 24 hours, and then the silk after standing is placed at 186 Combing three times on the combing machine, after the completion, use the soap-alkali method for silk scouring, the process is: preparation before scouring→pretreatment→primary scouring→re-scouring→softening and whitening→post-scouring treatment.

[0067] Scouring agents: the main scouring agent is soap, and the auxiliary scouring agents are soda ash, sodium phosphate, sodium phosphate, hydrosulfite, whitening agent, and softener.

[0068] (a) Preparation before training: water, steam, electricity, raw materials, chemical additives and various tools for use, balances, thermometers, clocks, hydrometers, etc.;

[0069] (b) Pretreatment: place the silk fiber in 0.5g / l soda ash solution (80°C) for 30min;

[0070] (c) Preliminary trai...

Embodiment 3

[0091] Earlier the silk short fiber of different sources is carded by above-mentioned (example 1 or 2) method, makes silk

[0092] The fiber is between 1.5cm-2.5cm, loosen and disperse after soap-alkali scouring, and spray 1.5% silver ion inorganic antibacterial agent evenly in layers. In the mechanical granulation process, the antibacterial ingredients are implanted into the particles so that To achieve the purpose of long-term antibacterial, granulation can be carried out twice, which can save expensive antibacterial agents and significantly improve the resilience of flocs. Before entering the constant temperature oven, the antibacterial agent in the spray emulsion is 1%. The feel of the sheet, the dry weight ratio of resin emulsion to silk is 1:100, the temperature of the constant temperature oven is 60°C, the weight of flakes per square meter is 75g, and the width of the door can reach 250cm.

[0093] In the manufacture technology of the present invention, the prescribing ...

Abstract

Functional silk non-woven wadding is prepared from natural silk, plant resin emulsion and inorganic nano bactericidal. The said emulsion is of self cross-linked anion resin, co-polymerized from acrylic diester, arylonitrile itaconic acid and N hydroxy acrylamide as cross-linking agent. The ratio of emulsion : silk is 100: (1.5-5.0) by dry weight. Silver ion nano bactericidal is also added into the wadding with the ratio of the bactericidal : silk is 100: (0.5-15.0). The product is soft and light, moisture-absorbing and gas permeable, high thermal insulation, elastic, water washing resistance, safety and usable widely.

Description

technical field [0001] The invention relates to a non-woven wadding, in particular to a production process of a functional silk non-woven wadding. Background technique [0002] Human beings have entered the 21st century with highly developed science and technology, and the textile consumption that people rely on for survival must be based on the theme of natural green environmental protection. However, with the continuous advancement of science and technology, the emergence of a large number of simulated chemical fibers has made silk protein fibers with a long history show many relative weaknesses, such as elasticity, washing performance, wrinkle resistance, coloring performance, etc., and become a green consumption for people. obstacles. Therefore, how to retain the natural quality of traditional silk and endow it with chemical fiber properties has become a technical problem to be solved by many enterprises. To be sure, if the above-mentioned "weakness" of silk is solved,...
