Lesson 15 The manufacture of hosiery on small-diameter circular machines

15.1 Types of hosiery

Hose, which have a leg-length extending above the knee

3
15.2 Classes of hosiery machines
Except for the few Griswold type hand-turned machines(Fig.4.4), all hosiery machines are of the revolving cylinder type. This arrangement offers the advantages of high revolution speeds, a simplified drive, and the possibility of selectively striping-in yarn from stationary packages placed at fixed feed positions around the cylinder. The three types of hosiery machines, in order of their increasing complexity and needle bed arrangement, are single cylinder, cylinder and dial and double cylinder.
Micromesh is similar although less effective because it contains less tuck stitches.

12.4.4 Needle selection shaping
In needle selection shaping, the selvedge needle(s) is introduced or withdrawn from the knitting width by means of needle selection. 1.By transferring and re-transferring rib loops in conjunction with needle bed racking 2.By pressing-off loops, or 3.By causing needles to hold their loops for large numbers of traverses

❖ 成形编织
▪ 为了达到成形的要求,可采用的 方法:
• 利用组织结构和织物密度的变化。 • 通过增减参加工作的针数使所编
织的产品的宽窄和形状发生变化。
▪成型是横机编织的一 个重要特点,也是横 机能够存在和发展的 一个重要原因。

❖ 起口与翻针
▪ 起口
• 2+1(假2+2)罗纹下摆采用2隔1 选针,前后针床针槽相错(针对 齿)编织,如右图第2、3横列所 示。但在空针上起头时,如果采 用这种排针容易形成大线圈,即 相邻两枚针形成一个线圈,为此, 一般先将后针床(或前针床)向 左(或向右)移动一个针距,如 右图第1横列所示,然后再进行正 常编织,就可以避免形成大线圈。
• 握持式放针,是使前面退出工作但 针钩里仍然含有线圈的织针重新进 入工作。(利用休止机)
• 将边缘线圈先套到新加入的针上, 然后将上一横列线圈套到移去线圈 的空针上,编织下一横列。
– 特点:较复杂,边缘质量最好。

20.1 Basic principles 基本原则

Carefully arranged variation of one or more of the above conditions enables patterns, surface interest, relief and open-work structures to be knitted, as the guide lines below indicate: Variation in the threading/穿纱的 of one or more guide bars (guides threaded with different types of yarn or empty guides without yarn). Variation in the extent of underlaps Varying the rate of warp supply/送纱比 or selectively tensioning the warp threads at certain courses.

The guide bar threading for one width repeat is usually shown in its correct relative position between the needle spaces at the first link of the design. Overlaps composed of only a single thread will be inclined, whereas loops produces by the overlaps of two bars lapping in opposition will be smaller and upright. Wales will be drawn together where underlaps pass across between them and will separate at points where no underlaps cross, producing net pillars/孔柱 in the former and net openings/孔眼 in the latter (Fig 20.2).

针织学(双语)课件Chapter17

The number of links per course /每横列所需链块数 is fixed for each machine. A minimum of two is usually required, with the underlap occurring between the second link of one course and the first link of the next.

17.5 Single needle bar structures
10
A swing motion (fig.17.1 A-A) and a shogging movement (fig.17.1 B-B) act at right-angles to each other in order for their threads to form overlap and underlap paths that combine as one thread path around the needles.

17.7 the chain links 链条

A chain notation/垫纱数码记录 is a list ,in correct sequence of chain link numbers, spaced into knitting cycles, for each guide bar necessary to produce a particular fabric structure repeat (Fig.17.4D). The difference between the first two links is normally the overlap.
