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, dirt, and 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, barbed rollers and cylinders, further shake off the dust and sundries adhering to the silk, and compare the length and length of the silk fibers Consistent and easy to handle in the next process.

[0043] Evenly spraying concentration on the short silk fibers after opening is 1.5% aminohydroxy acidic silicone emulsion (softening agent) and let it stand for 24 hours.

[0044] The pre-set silk is combed with a 186 combing machine, mainly to achieve that the silk does not contain threads and sundries, so that the length of the fiber is between 1.5-2.5. Then use the contract detergent-method for silk scouring:

[0045] (a)...

Embodiment 2

[0065] The silk head purchased from the silk textile factory is first opened twice on the opener with steel nails, and then layered and evenly sprayed with 1.5% softener and left to stand for 24 hours, and then the left silk is placed in 186 precision Comb three times on the carding machine. After finishing, use soap-alkali method to refine the silk. The process flow is: preparation before refining→pretreatment→primary refining→re-training→softening and whitening→post-scouring treatment:

[0066] 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.

[0067] (a) Preparation before training: water, steam, electricity, raw materials, chemical additives and various tools, scales, thermometers, clocks, hydrometers, etc.

[0068] (b) Pretreatment: Put the silk fiber in 0.5g / l soda ash solution for 30min (hot solution at 80°C).

[0069] (c) initial training: ...

Embodiment 3

[0089] First, preset and comb silk staple fibers from different sources according to the above method (Example 1 or 2), so that the silk fibers are between 1.5-2.5 cm, loosen and break up after scouring by soap-alkali method, and spray evenly in layers 1.5% silver ion inorganic antibacterial agent, in the mechanical granulation process, the antibacterial component is implanted into the particles to achieve the purpose of long-term antibacterial, and can be granulated twice, which can save expensive antibacterial agents and significantly improve the flocculation. The resilience of the sheet, before entering the constant temperature oven, the antibacterial agent in the spray glue emulsion is 1%, in order to improve the feel of the floc, the dry weight ratio of the plant resin emulsion and silk is 1: 100, and the temperature of the constant temperature oven is 60 ℃. The weight of the piece per square meter is 75g, and the width of the door can reach 250cm.

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 sheet, in particular to a functional silk non-woven wadding sheet. 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. Therefore, how to endow traditional silk with natural quality and chemical fiber performance has become a technical problem to be solved by many enterprises. To be sure, if these "weaknesses" of silk are resolved, along with the acceleration of the process of gl...
