Problems solved by technology

For the current processing method, due to the large number of yarn joints and uneven twist, the strength value of the fabric has a large deviation and the air permeability is uneven.
Moreover, in the weaving process, due to the large number of yarn joints, the number of shutdowns increases, the production efficiency is greatly reduced, and the stability of the finished product is reduced, resulting in low performance of the finished product.

Embodiment 1

[0022] A kind of industrial yarn and fabric, it selects polyphenylene sulfide fiber as the raw material of yarn and fabric, through the following process:

[0023] Cotton cleaning→carding→drawing→roving→spinning→winding→doubling→two-for-one twisting→yarn

[0024] After the yarn is produced by the above processing technology, the weaving process is carried out, and then the number of joints of the inner strands with a length of 280m and a width of 2.32m is counted and measured. The results are based on 100m 2 The area conversion results are shown in Table 1 below.

Embodiment 2

[0032] A kind of industrial yarn and fabric, it selects polyphenylene sulfide fiber as the raw material of yarn and fabric, through the following process:

[0033] Cotton cleaning→carding→drawing→roving→spinning→winding (by air-twisting joint method)→doubling (by air-twisting joint method)→two-fold twisting (by air-twisting joint method)→yarn

[0034] After the yarn is produced by the above processing technology, the weaving process is carried out, and then the number of joints of the inner strands with a length of 280m and a width of 2.32m is counted and measured. The results are based on 100m 2 The area conversion results are shown in Table 2 below.

Embodiment 3

[0042]A kind of industrial yarn and fabric, it selects polyphenylene sulfide fiber as the raw material of yarn and fabric, through the following process:

[0043] Cotton cleaning→carding→drawing→roving→spinning→winding (by air-twisted joint method)→doubling (by air-twisted joint method)→twisted thread (by air-twisted joint method)→winding (by air-twisted joint method) piecing method) → yarn

[0044] After the yarn is produced by the above processing technology, the weaving process is carried out, and then the number of joints of the inner strands with a length of 280m and a width of 2.32m is counted and measured. The results are based on 100m 2 The area conversion results are shown in Table 2 below.

Abstract

The invention discloses an industrial yarn and an industrial fabric as well as a use thereof. Yarn is the yarn which is made from a raw material of heat resistant fiber, after the yarn is weaved, the joint number of the yarn in a fabric is below 10 / 100m2. Tensile strength of the fabric, of which the longitude direction is above 500 N / 5cm based on JIS L 10968.12.1A law, and the fabric is applied in the filtering material field and a reinforcement fabric of non-woven fabric. The invention has the advantages of reducing the joint number of the yarn, reducing unevenness of yarn twist, improving strength of the fabric and stability of ventilation degree value and improving overall performance of the finished product.

Description

Technical field: [0001] The invention relates to a yarn and a fabric used in the industrial field, which is suitable for the filtration of gas-solid and liquid-solid forms, including the filtration of industrial smoke and dust, the filtration of water treatment, and the fabric and the yarn for the fabric. Background technique: [0002] With the progress of society, people have higher and higher requirements for the environment and environmental protection. Of course, the relevant laws and regulations of the country are becoming more and more strict. Therefore, for the environmental protection and industrial industries, this popular industry in the 21st century, the requirements for its products are getting higher and higher. For the field of flue gas filtration, more and more coal-fired power plants and waste incineration plants at home and abroad use bag filters. The bag filter is one of the most effective technical equipment for controlling industrial dust and smoke at ho...
