Abstract

Usage: during the initial processing of kenaf bast to obtain fiber from it. SUMMARY OF THE INVENTION: The apical part of the sheaves is removed by cutting off its non-fiber part 15-20 cm long. The main part of the sheaves is combed from leaves, flowers and seed bolls. Bales are formed from the main part of the sheaves. Their lobe and machining are carried out.

Description

FIELD OF THE INVENTION This invention relates to a primary treatment of bast crops, which can be used in the primary treatment of Kenaf bast.

A known method of primary processing of kenaf bast, which consists in the formation of bales from sheaf bast, their lobes and machining.

The application of this method showed that the presence of leaves, flowers, seed bolls, and also non-fiber tops in the bast reduces the yield and quality of the fiber, worsens environmental protection, as in the process of the forehead lobe, the quality of the washing liquid deteriorates due to their decay.

The closest analogue is the primary processing method, including cutting the apical part 50-70 cm long from the main part, forming bales separately from the apical and main parts of the sheaves, the bobbin and the machining.

The disadvantage of this method is to reduce the yield of long fiber by cutting off the fibrous apical part of the bast, creating additional labor costs when forming bales separately from the apical and main parts of the sheaves and their separate lobe.

An object of the invention is to improve quality and increase fiber yield.

The stated goal is achieved in that the top part of the sheaves is removed by cutting its non-fiber part 15-20 cm long, followed by stripping the main part of the sheaves from leaves, flowers and seed boxes, the formation of bales is made from the main part of the sheaves.

The method is carried out as follows (example of a specific embodiment).

15–20 cm long apical part is removed from the sheafs of bast by cutting, then leaves and seed boxes are removed from the remaining part by stripping, then bales are formed from sheaves, they are made from the sheaves and machined.

Using the proposed method allows to increase the fiber yield by 4- b%, increase its quality by 0.3 grades and improve environmental protection due to

the absence of removed leaves, flowers, seed bolls and non-fiber tops in the process of wetting, and also allows the use of these non-fiber impurities in livestock farming as livestock feed,

In order to establish the length of the removed non-fibrous part (tops) of the bast, the bast length is measured from the cut-off point (butt) to the growth point. Then, fiber is obtained by the lobe and its length is measured. The difference between the length of the bast and volcna shows the portion of the non-fibrous apex of the bast.

As a result of studies, it was found that the new-fiber tops do not exceed 15-20 cm.

To determine the influence of non-fibrous impurities (leaves, seed bolls, flowers, non-fibrous tips) of the bast on the yield and quality of fiber, a sheaf is selected from the batch of bast and divided into two parts, each of which is weighed.

From the first part of the sheaf, fiber is obtained in the existing way, and from the second part - the proposed one.

A comparison of the obtained experimental results showed that with the proposed method, the fiber yield is 4-6% (abs.) Higher and its quality is O. Zsorta better than fiber obtained by the existing method.

To establish the use of leaves, seed boxes,

flowers and non-fibrous apices as animal feed, the fodder qualities of non-fibrous impurities of Kenaf bast were determined by zootechnical analysis.

The analysis shows a rather high

nutrient content in them, i.e. in terms of protein, they are equal to alfalfa.

Seed boxes contain 16.5%

protein and 9.16% fat, and the leaves, respectively, 17.9 and 8.3% and the non-fibrous tips are 16, 7 and 3.9%.

As a result of the study, the possibility of using non-fibrous Kenaf impurities as feed in animal husbandry was established.
