摘要

本實驗主要以Tencel/Cotton交織物於有張力及無張力兩種加工狀態下，以氫氧化鉀強鹼劑進行絲光加工，並改變絲光鹼劑的濃度及處理的溫度與時間，以探討張力及其他加工條件對Tencel/Cotton交織物的絲光效果，染色性，經緯向強力，乾濕抗縐性，經緯向收縮率及經緯向柔軟度的影響。由實驗結果得知：鹼濃度的增加，將使織物呈明顯收縮及柔軟度下降，又絲光織物之抗縐性以有張力者為佳，至於絲光性(BAN值)及染色性(K/S值)係隨鹼濃度增加而提高，且有張力者比無張力者為佳。

The alkali treatment of Tencel/Cotton fabric using potassium hydrate (KOH) between treatment under constant fabric length and width (as tension mercerization) and treatment without tension (as slack mercerization) were investigated. The influences of tension, concentration of alkali agents, treating temperatures and time on mercerization and physical properties of Tencel/Cotton fabric in series had been studied. Treating Tencel/Cotton fabric in a highly concentrated alkali solution induces fabric shrinkage in width and length which is not the tension applied. The mercerization tends to decrease the softness of Tencel/Cotton fabric. In addition, the tension mercerization was better dry &wet wrinkle recovery than slack mercerization. The barium activity number (i.e. BAN value) of mercerized fabric and K/S value of dyed fabric increased with increasing concentration of alkali agent , and the tension mercerization was better effectiveness than the other.
