Embodiment 1

[0041] see figure 1 , a drying device in a raw silk degumming process according to a preferred embodiment of the present invention comprises a drying box 3, which is a thermal environment inside the drying box 3, and its temperature can be set according to needs, and the drying box 3 includes a lower inlet port and a Top exit port. The tow 1 before drying enters the drying oven 3 from the inlet end, and while drying is completed in the drying oven 3, the elasticity and bulkiness are increased, and the tow 2 after drying passes through the outlet end. A winding mechanism is arranged at the outlet end of the drying box 3, and the dried tow 2 is wound into a required package by the winding mechanism.

[0042] Drying box 3 is provided with tow cover 6 and air supply unit 4, and tow cover 6 is used for passing tow to be dried, and tow cover 6 is generally conical, and its height is 30cm, and the side wall of taper and vertical The angle α in the vertical direction is 10 degrees. ...

Embodiment 2

[0045] This embodiment provides a drying method in the raw silk degumming process, which is carried out by using the drying device in Embodiment 1, and the specific steps are as follows:

[0046] 1) The degummed raw silk tow after washing passes through the drying oven 3 continuously and evenly at a certain pulling speed (speed 0.2m / s). The linear density of the tow can be 20 / 22D, 40 / 44D, 60 / 66D, etc. The temperature inside the box 3 was 100°C. After washing, the degummed raw silk bundle enters the drying box 3, enters from the bottom opening 62 of the tow cover 6, and passes through the top opening 61. During this process, the air supply unit 4 supplies air from the obliquely downward side of the bottom opening 62 to generate the air supply airflow 5 , the air direction is from bottom to top, and forms a certain angle with the horizontal plane, and the angle can be selected as 30 degrees. The falling point of the blowing air flow 5 on the tow cover 6 is controlled within the...

Abstract

The invention relates to a drying device and drying method in the raw silk degumming process. The drying device comprises a drying box. A strand cover and an air supply unit are arranged in the dryingbox. The strand cover is used for allowing a to-be-dried strand to penetrate through. The top and the bottom of the strand cover are provided with a top opening and a bottom opening respectively. A protruding part is arranged on part of the side wall of the strand cover and protrudes towards the outside the strand cover. The air supply unit is used for blowing supplied air flow into the strand cover to dry the strand. The falling point of the supplied air flow is located in the protruding part of the strand cover. By means of the drying device, silk can be endowed with the special elastic property and fluffy property in the drying stage of raw silk degumming.

Description

technical field [0001] The invention relates to the field of textile science and technology, in particular to a drying device and a drying method in the process of degumming raw silk. Background technique [0002] Silk is the fiber that solidifies after the silk liquid in the silkworm body is spouted out, and is called cocoon silk. Raw silk is the product obtained after silkworm cocoon reeling, commonly known as factory silk. Among them, the protein is about 70-80%, and the sericin is about 20-30%. [0003] In raw silk, sericin is irregularly coated on the surface of silk fibroin in scales to protect silk fibroin. But too much sericin will affect the luster and feel of silk, and will also affect the subsequent processing of silk products. Therefore, the sericin on the silk must be removed. The process of removing sericin is called degumming. After removing part of the gelatin, the raw silk is soft and shiny, which is called "cooked silk". [0004] The technological pro...
