Abstract.The article presents the results of a study of the properties of curved fibrous waste. Standards determined the availability of fibers of acceptable length for the production of yarn from used fibers. Cleaning options are available depending on the type of waste in different plants. A spinning plan is developed and the test results of the physicomechanical properties of yarn samples are analyzed. The possibility of obtaining medium-density yarn with attachment in a mixture of spins of the group directly under conditions of maximum purification and high uniformity of mixing of the components is shown.

At present, improving the quality of textile products, in particular yarn from the same raw materials, is an urgent task to help increase the export opportunities of relevant market demand products. The production of high- quality competitive products in the world market, based on the use of new, more advanced technologies, is the most important task of the textile industry. The quality of textile products depends largely on the uniformity, purity and strength of the yarn. Improving the quality of textile products can be achieved through the introduction and use of modern equipment based on advanced technological principles [1 … 9].

The efficiency of spinning production largely depends on the rational use of raw materials, which to a greater extent affects the cost of yarn. The release of fibrous waste from textile fiber processing is known in spinning machines and engravers. Direct waste is of great importance among them, since it allows to save high- quality fiber and reduce the cost of production [1 … 9].

In production conditions, to produce [8] fabric, reinforced yarn was used as weft, and linear density 25 tex yarn was used as the main threads.

The table shows that the properties of the harsh fabrics of I twisted yarn meet the requirements of GOST, and the properties of the fabric fabric from reinforced yarn are higher than these requirements.

For an hour, the breakage of the yarn on the looms was checked. There are 10 cliffs in the reinforced yarn of all: 6 of them are in the base, and 4 in the duck; and in twisted yarn there are only 15 clippings: 7 at the base of 8 in the duck. The productivity of looms is 3.54 m / hour of twisted yarn 3.01 m / hour.

From the indicators it is seen that the use of reinforced yarn increases the quality indicators of the fabric.

The prepared harsh fabrics were rewound onto a roll, and the LBOX FIRM "Kyoto" bleaching machines were filled with E, where they bleached, steamed, washed and dried the fabric. We checked the capillarity and whiteness of the fabric leaving the machine.

The table shows that laboratory tests for all samples meet the requirements of technical conditions, and capillarity is higher than standard.

To improve the properties of the tissue, it was emulsified using an emulsifying unit.

After emulsification, tissue samples are refueled on pile machines. Samples of three variants of the fabric obtained from reinforced yarn gave a satisfactory result in

the yield of nap even at one transition, and the serial fabric was released repeatedly, because in the first combing, the pile of fabric came out unsatisfactorily. If you change the parameters of the machines, the material will deteriorate.

For the prepared materials shown in Figure N
