Problems solved by technology

At present, the yarn knots of the base fabric for filter cloth mainly include manual knotting and mechanical knotting, and the yarn knots obtained by these methods are common: large knots, low strength, and large differences in the strength of finished fabrics , uneven ventilation, etc.
At the same time, in the weaving process, due to the large knots of the yarn, it is difficult to pass through the reed teeth, knot slippage, etc., resulting in increased yarn breakage and increased loom stoppages, which affect the weaving production efficiency and the overall performance of the fabric (such as: fabric Surface appearance, fabric strength, strength uniformity, etc.)

Embodiment 1

[0023] An industrial yarn and fabric. Polyphenylene sulfide fiber is selected as the raw material of the yarn and fabric. After the 531 Denier double-ply yarn is produced by air-twisting, the weaving process is carried out, and the length is 400m and the width is 400m. 2. The number of knot weaving stops of the yarn within 32m is counted and measured, and the results are calculated in rounds / meter. The results are shown in Table 1 below.

Embodiment 2

[0031] A kind of industrial yarn and fabric. Polyphenylene sulfide fiber is selected as the raw material of yarn and fabric. After the single-strand yarn of 760 Denier is produced by the air-twisting method, the weaving process is carried out, and the length is 350m and the width is 350m. 2. The number of knot weaving stops of the yarn within 45m is counted and measured, and the results are calculated in rounds / meter. The results are shown in Table 2 below.

Abstract

The invention discloses an industrial yarn and a fabric manufactured by the yarn. The yarn takes heat resistant fiber as raw material, and the diameter of the yarn at the knot is 0.8 to 2.5 times of that of the yarn at non-knot position. The fabric has small knots and high intensity. The invention provides a product for reducing broken end and machine halt due to big knots and low intensity of yarn when the fabric is weaved, thereby improving the weaving efficiency, the intensity of fabric and the stability of permeability value, and enhancing the combination property of finished goods.

Description

Technical field: [0001] The invention relates to a yarn and fabric used in the industrial field. It is a fabric and yarn used in the field of filtration of gas-solid, liquid-solid and other forms (including filtration of industrial smoke and dust, filtration of water treatment, etc.) . Background technique: [0002] In recent years, with the rapid development of industry, industrial pollution has become increasingly serious, which has endangered the natural environment and people's health. Flue gas dust removal is an important part of pollution control, and bag dust removal is an effective method for flue gas treatment. At present, the country is paying more and more attention to environmental protection issues, especially in the "People's Congress" to include key issues to be resolved. As early as January 1, 2004, coal-fired boilers in thermal power plants and other industries implemented 50mg / m 3 In order to achieve this new standard, it is imperative to adopt the most effect...
