1. Textile English TASK 4 HAVE A LOOK AT THE FABRICS AND PRODUCTION- An Outline of the Weaving Process

2. In order to interlace warp and weft threads to produce fabric on any type of weaving machine, three operations are necessary:threads Paragraph Ⅰ

3. (a) shedding: separating the warp threads into two layers to form a shed.shedding Paragraph Ⅰ 1 2 织物 经纱

4. Paragraph Ⅰ (b) picking: passing the weft thread, which traverses across the fabric, through the shed.pickingtraverses

5. Paragraph Ⅰ (c) beating-up: pushing the newly inserted weft, known as the pick, into the already woven fabric at a point known as the fell.beating-upfell

6. Paragraph Ⅱ These three operations are often called the primary motions of weaving and must occur in a given sequence, but their precise timing in relation to one another is also of extreme importance and will be considered in detail.sequence Two additional operations are essential if weaving is to be continuous:

7. (d) warp control (or let- off): this motion delivers warp to the weaving area at the required rate and at a suitable constant tension by unwinding it from a flanged tube known as the weaver’s beam.let- offflanged tube Paragraph Ⅲ

8. (e) cloth control (or take- up): this motion withdraws fabric from the weaving area at the constant rate that will give the required pick- spacing and then winds it onto a roller.take- upwithdraws Paragraph Ⅲ

9. The yarn from the weaver’s beam passes round the back rest and comes forward through the drop wires of the warp stop motion to the heald, which are responsible for separating the warp sheet for the purpose of shed formation.drop wires heald Paragraph Ⅳ

10. It then passes through the reed, which holds the threads at uniform spacing and is also responsible for beating-up the weft thread that has been left in the triangular warp shed formed by the two warp sheets and the reed.triangular Paragraph Ⅳ

11. Temples hold the cloth firm at the fell to assist in the formation of a uniform fabric, which then passes over the front rest, round the take-up roller and onto the cloth roller. Templesthe front restcloth roller Paragraph Ⅳ
