7.5 Double width cloth 1. Concept 2. The main points of designing a double width cloth 3. The main points of weaving plan
1. Concept: • Double width fabrics are widely used for industrial purpose, such as paper making blanket. • Double width fabric is a kind of double weave which one selvedge is joined. See Fig. 7.22. Fig. 7.22 Construction of double width weave
2. The main points of designing double width cloth • (1) Base weave selection: Base weave should be simple, such as plain, twills, and regular satin/sateen, nevertheless, the base weave must meet the requirements of the end product. • (2) Arrangement of face and back threads Arrangement in warp way of face and back can be 1:1, 2:2, and usually 1:1 is considered firstly. Arrangement in weft way of face and back must be 2:2.
(3) The first insertion is limitation in direction. See Fig 7.22. where: The base weave is 1/1 plain. Arrangement in warp direction is 1:1. Arrangement in weft direction is 2:2. A—selvedge cord B—stitching yarn to achieve an evenness selvedge which will be removed after the fabric is woven
3. The main points of weaving plan: • (1) The material, count, weave of the face and back should be the same. Therefore, one beam is adaptable to construct the weave. • (2) Either one shuttle or multi-shuttle is suitable. • (3) Using grouped draft or straight draft. Grouped draft can easily get even tension of warp ends. • (4) Selvedge cord is used to achieve the evenness of selvedges.
