Embodiment Construction

[0018] Singeing: Singeing is the same as ordinary cotton fabrics, using two fronts and one back, the speed is 80-90m / min, and the effect reaches 3-4 grades.

[0019] Descouring and bleaching treatment: According to the performance of Tencel fiber and the production experience of cotton fabric, Tencel cotton is suitable for cold pad batch and continuous open width pretreatment. The cold pad batch process has low energy consumption and low water consumption. It is a clean production process recommended by the printing and dyeing industry. It uses a high-efficiency osmotic scouring agent that integrates the functions of dispersing, emulsifying, scouring, cleaning, and osmosis. Under the action, the impurities on the swollen pulp and cotton fibers are removed by sufficient steam and water washing. Continuous open width utilizes high-efficiency pre-processing equipment, adopts AC frequency conversion drive, composite steamer, washing step-by-step reverse flow and other technologies...

Abstract

The invention discloses a dyeing and finishing technique of a tencel and cotton blended fabric. Firstly, textiles are treated by two positive and one reverse singeing, desizing and scouring and bleaching treatment, clipless mercerizing by a clipless mercerizing machine, and continuous open width pad dyeing, then loose color of the textiles and surface active agent are removed by washing to carry out easy care treatment, finally softening is carried out by adopting mechanical force. The invention has simple process. The invention greatly increases the strike immigration performance of the textiles and is easily dyed uniformly, thus improving the quality of tencel and cotton fabric and the product levels. The dyed surface fabric has good textural quality which is similar to tencel, soft hand feeling, soft light color, comfortable and breathable wear, easy care, and can be widely applied to shirt fabrics with top quality and home surface fabrics.

Description

【Technical field】 [0001] The invention relates to the field of textile printing and dyeing, in particular to a dyeing and finishing process for fabrics blended with tencel and cotton. 【Background technique】 [0002] The bonding force between Tencel fibrils is weak (that is, the characteristics of fibrillation). In a wet state and under the action of mechanical force, the fiber longitudinal surface splits to produce microfibers. After finishing, the fabric has a special velvet effect. In wet state, the lateral expansion can reach 40%, but the length remains unchanged. After the fabric is wet-processed, the gap between the yarns becomes larger, giving the fabric a sense of drape and fluidity. Tencel fiber has high crystallinity, long crystal region, dry strength close to that of polyester fiber, wet strength only drops 15%, higher than wet cotton, while viscose fiber wet strength drops 50%. Tencel fiber has a high Young's modulus, so the dimensional stability of the fabric is...
