Embodiment 1

[0024] 1. Preparation of strong alkaline electrolyzed water

[0025] The present invention is based on the principle of electrolysis of water-chemical reaction, water is a weak electrolyte, and there is an ionization balance inside, and the balance formula is expressed as:

[0026] ①H 2 O = H (+) + OH (-)

[0027] ②H (+) + OH (-) = H 2 o

[0028] v① = v② v is the reaction speed;

[0029] Under the action of direct current, hydrogen and oxygen are released, and the hydrogen ions and hydroxide ions are continuously reduced, breaking the equilibrium system and making the water continuously ionized, and v①>v②, so that the reaction can continue.

[0030] Anode reaction: 4OH (-) -4e (-) = 2H 2 O+O 2 ↑

[0031] Cathode reaction: 2H(+)+2e(-) = H 2 ↑

[0032] Total reaction: 2H 2 O=(power on)2H 2 ↑+O 2 ↑

[0033] water (H 2 O) is electrolyzed to generate electrolyzed water. Current passing through water (H 2 O), oxygen is formed at the anode and hydrogen is for...

[0041] 1. Silk reeling with strong alkaline electrolyzed water (low temperature reeling)

[0042] In this example, the strong alkaline electrolyzed water prepared in Example 1 is used to reel a grain of silk using a new silk reeling process. The process steps and conditions are as follows: select a cocoon shell with a uniform texture, and place it at a pH of 11.50 with a bath ratio of 1. : 40 strong alkaline electrolyzed water, in a water-bath shaker with a temperature of 70 °C and a rotation speed of 120 rpm, immerse silkworm cocoons for 5-7 minutes; take out the treated silkworm cocoons and place them at 50-70 °C , pH11.50 warm water for constant temperature reeling. When reeling, according to the sequence of silk fibers, one strand is formed every 100 times, and then the strands are interlocked in sequence, the first to tenth strands are interlocked in sequence, so as not to disturb the order of silk fibers, and obtain the cocoon of silk reeling under low temperature condit...

[0057] Preparation of strong alkaline electrolyzed water with electrolysis accelerator:

[0058]In this embodiment, the electrolytic cell is used to feed ordinary tap water containing 0.01% NaCl electrolyte promoter, the DC power supply is turned on to make the electrolytic cell work, the alkaline electrolyzed water at the cathode outlet is collected, and the current or tap water flow rate is adjusted to obtain a pH of 12.10. After the electrolyzed water is filtered or left standing overnight, the filtrate or supernatant is used for all experiments of the present invention. The specific experiment is as follows: tap water is directly passed into the electrolytic cell for electrolysis, and 50L of ordinary tap water (~pH8.04) is used to produce 25L of acidic electrolyzed water (pH2.50) and 25L of alkaline electrolyzed water (pH12.10).

[0059] The silk reeling process provided in Example 2 is used for reeling to obtain silk raw silk, and the reeling results meet the quality requ...

Abstract

The invention discloses a method for reeling silk at low temperature by utilizing strongly alkaline electrolyzed water, falling into silk making technical field. The method includes subjecting common tap water to electrolytic treatment via water electrolyzer or electrolytic cell, to obtain strongly alkaline electrolyzed water with pH of 11.0-12.0; performing constant-temperature oscillation swelling soaking treatment on silkworm cocoon in strongly alkaline electrolyzed water at 60-80 DEG C directly for 5-10 min; and taking strongly alkaline electrolyzed water as reeling hot water bath, transferring the swollen silkworm cocoon to the reeling hot water bath at 40-70 DEG C, and immediately reeling silk, to obtain raw silk product. The inventive method performs reeling at low temperature, to improve product quality and save energy. The invention can realize industrial production of strongly alkaline electrolyzed water at low cost and high yield, high-efficiency low-cost recovery of sericin, and cyclic utilization of reeling waste water after simple purification treatment, to thereby avoid environmental pollution caused by a large amount of waste liquid.

Description

technical field [0001] The invention relates to a technique and process for processing raw silk in strong alkaline electrolyzed water. This strong alkaline electrolyzed water can be used as a low temperature cocoon swelling agent and silk reeling soup bath. This technology is also involved in the field of low-cost, green recycled sericin in silkworm cocoon swelling agent and silk reeling soup bath. Background technique [0002] Silk is a natural protein fiber produced by silkworms, and the sericulture and silk industries are traditionally advantageous industries in my country. In the world, it has the longest history and traditional silk culture. [0003] Silk fiber is mainly composed of 65-75% silk fibroin, 20-30% sericin and about 5% wax, pigment, sugar and impurities. Among them, silk fibroin is a kind of crystalline fibrous protein, and it is covered with a colloidal sericin protein, which plays the role of glueing silk fibroin fibers and reinforcing the cocoon space,...
