針織面料常見的瑕疵匯總
[ 發布時間:2014-12-10 15:25:45  訪問量:3723  字體: ]

破洞:在織物成圈中,有一根或幾根紗線斷裂,線圈脫撒,稱作破洞。

漏針:紗線未斷裂,但針鉤內未墊入新紗線,造成線圈脫散的直向疵點,叫漏針。針盤織針形成的漏針,叫里漏針,針筒織針形成的漏針,叫外漏針。

花針:在成圈過程中,舊線圈為脫出針鉤,又吃進新紗線,形成新線圈,新舊線圈重合在一起,形成的疵點叫花針,有直條型花針和分散型花針。

吊針:是花針的一種特殊類型。在一枚織針上連續多次成圈,不脫出舊線圈,導致多個線圈集中在針鉤下,形成的疵點叫吊針。

稀密路:在布面縱向形成松或緊的條紋,織物線圈太長或太短,叫稀密路,俗稱厚薄針。

短紗:俗稱豁子。一路紗線斷裂后,織針不能墊到紗線成圈,在布面橫向形成一定長度的疵點叫斷紗。

橫路:又稱橫條。在織物的若干橫列中線圈由大到小,再由小到大發生周期性的變化,呈現稀密不均的橫向隱條叫橫路。

油污:織造的時候由于織針或機臺上的油布沾到布面而產生的異常。 

混紗:在織造掛紗的時候,批號或紗支型號搞錯。

Pre-requisites for faultless knitwear production

無瑕疵針織布生產的必要條件

Assume that circular knitting machines, currently on the market are suitable for processing staple fibre and filament yarns.

我們假定市面上的針織大圓機適合加工長纖或短纖紗線

With regards to the state of the machines the following points must be noted

機器的如下狀態必須注意

The machine must be installed on a horizontal floor and, as far as possible, without any vibrations.

機器需要安裝在平穩的地面上,盡可能保證沒有任何的震動。

The bobbin carriers must be mounted in such a way, that the yarn does not rub against the sides of the package when it is withdrawn.

紗架的安裝達到這樣的狀態,紗線輸送的時候不會與紗筒摩擦。

Yarn should be guided from the package up to the knitting area without unnecessary deviations in order to avoid additional increases in tension.

導入到編織區域的紗線保證沒有不必要的偏差,避免額外張力。

If basic knitted structures are used to a large extent, the machines should be equipped with yarn feeding units which generate a constant and low yarn tension (running-in tension) and deliver a uniform yarn length.

如果編織的大部分是基本的針織結構,機器應該配備儲紗器,產生穩定的,固定紗長的低紗線張力輸紗。

Yarn guide devices must be flawless, eyelets made of porcelain or sintered ceramic must have a smooth surface without any furrows.

導紗器必須完美無瑕,陶瓷導紗孔表面平滑無皺紋。

The needles must also be flawless. If synthetic yarns are processed to a large extent in a 3 shift operation, they might have to be renewed just after 6 months.

舌針完美無瑕。如果三班倒大批量生產人造纖維, 舌針在六個月后有必要更新。

The shape of the needle,and especially of the needle hooks, must be adapted to the machine gauge and the yarn count.

舌針的形狀,尤其是針舌,要根據機器的針距和紗線的紗支來配套。

Needle beds are subjected to a high strain while producing tight fabrics from synthetic yarns. If wear and tear occurs here it can cause problems in subsequent processing(Roughening, cracks)

針床在生產比較厚的人造纖維布料時,承受較高生產張力。如果發生磨損, 在后續的生產中會產生較嚴重問題

The drive to the needle dial and needle cylinder must be free from play.

The needle beds must be exaxtly centered towards one another.

針筒和針盤相對同心。
