Problems solved by technology

The silk quilt with silk as the inner tube has unique qualities and advantages such as close-fitting warmth, fluffy and soft, breathable and healthy. The existing silk is easy to cake after being washed. The reason is that the silk contains a lot of oil and glue. After washing and stirring , the oil glue and the silk mixed board are agglomerated. These problems are mainly caused by defects in the process, especially in the preparation of the refined product. If the oil and impurities of the refined product are not thoroughly removed Too much, the silk quilt is easy to harden and the quality is poor

Embodiment 1

[0030] The method for preparing dried silk product comprises the following steps in turn: putting silk cocoons into a scourer for soaking, adding 5% of the cocoon weight of soda ash and 1% of the silk cocoon weight of detergent and keeping the pH of the soaking solution at 8.5-10.5, controlling The water temperature is 80°C, and the soaking time is 12 hours; the soaked silkworm cocoons are taken out of the washing machine and put into the dehydrator for the first dehydration; the silkworm cocoons after the first dehydration are opened by the cotton opener to form cotton sheets; the cotton sheets are put into the water tank For the second soaking, add 3% soda ash based on the weight of the sheet, control the water temperature at 80°C, and soak for 60 hours; after the second soaking, the sheet is dehydrated twice, then rinsed, and then dehydrated three times; the sheet after the third dehydration Put it in the water tank for bleaching, add 20% hydrogen peroxide of the weight of t...

Embodiment 2

[0034] In Example 2: add 9% soda ash and 1.3% detergent based on silkworm cocoon weight for the initial soaking, control the water temperature at 100°C, and soak for 18 hours; control the water temperature for the second soaking at 100°C, and soak for 72 hours; 40% of the sheet weight hydrogen peroxide, bleaching time 16h; wet the sheet into 32 ° C water; other steps and parameters are the same as in Example 1.

Embodiment 3

[0036] In Example 3: add 7% soda ash and 1.1% detergent based on silkworm cocoon weight for the initial soaking, control the water temperature at 90°C, and soak for 15 hours; control the water temperature for the second soaking at 90°C, and soak for 70 hours; 40% of the weight of the sheet with hydrogen peroxide, bleaching time 15h; when wet, put the sheet into water at 30°C to wet; other steps and parameters are the same as in Example 1.

[0037] With embodiment 1, 2, 3 the fine dried product of silk made, the data detected by National Textile Products Quality Inspection and Inspection Center (Jiangyin) are as follows:

[0038]

[0039] From Examples 1, 2, and 3, it can be seen that the oil content of the dry product made by the method of the present invention is far lower than the industry standard, and the finished product made from the dry product with a low oil content is not easy to harden after washing, and the dry product after repeated rinsing The impurity rate of ...

Abstract

The invention discloses a method for preparing silk fine dried product, which comprises the following steps: primary soaking, primary dehydration, foaming, secondary soaking, second and third dehydration, bleaching, fourth dehydration, reduction, tank washing and five dehydration, wetting, After six times of dehydration, fluffing, drying, awakening, and multiple rinsing, the dry product has a lower impurity rate and improves the quality of the entire product.

Description

technical field [0001] The invention relates to the field of silk processing, in particular to a method for preparing dried silk products. Background technique [0002] Silk is a natural fiber that integrates lightness, softness and fineness in nature. It is known as "the second skin of the human body" and is called "the queen of fibers" by the industry. The silk quilt with silk as the inner tube has unique qualities and advantages such as close-fitting warmth, fluffy and soft, breathable and healthy. The existing silk is easy to cake after being washed. The reason is that the silk contains a lot of oil and glue. After washing and stirring , the oil glue and the silk mixed board are agglomerated. These problems are mainly caused by defects in the process, especially in the preparation of the refined product. If the oil and impurities of the refined product are not thoroughly removed Too much, the silk made is easy to harden, and the quality is poor. Contents of the invent...
