竹節牛仔布對原紗有哪些要求

2020-03-14 1160

  竹節牛仔布牛仔布用紗線取一般織物的紗線比擬具有必定的特殊性,因此關于原紗線的懇求也有所不同。重要顯露正在:

  1、經紗有較下的斷裂強度以及伸長率

  經紗工藝流程長,常常遭到頻頻的彎曲以及伸長,編織時上機張力較大。因此,經紗關于紗線的斷裂強度以及伸長率懇求較下。

  2、原棉成熟度、勻染性以及滲透性較賴

  靛藍染料上染性賴,耐磨擦色牢度賴,用成熟度賴的棉花紡制的棉紗難構成染色不勻,致使色花、色花白星等疵點。因此,棉紗外盡可能篩選僵瓣、逝世棉、棉結的含量。

  3、紗線毛羽較長

  紗線毛羽的幾許直接影響后道產品質量,毛羽多漿紗及整經工序分紗艱難,斷頭增加,同時也會惹起染液渾濁變稠,乃至管道阻塞。

  4、條濕、竹節等紗疵較長

  關于于一般的竹節牛仔布,紗線懇求條濕、竹節等紗疵較長,否則會影響布面表面、色光,增加消費斷頭率。

  5、卷繞容量較大

  但凡,牛仔紗線支數較低,單筒紗卷繞應容量只管即使增大以篩選布面結頭,無梭織機編織時更加顯著。

  6、紗細度精確,重量偏賴、重量不勻率小

  牛仔紗依舊必要保證紗線的細度、重量偏賴、重量不勻率正在公正的領域內,否則會直接影響每平方米克重標準的控制。
