A kind of anti-shrinkage and anti-wrinkle treatment process of pure cotton fabric

Abstract

The invention discloses a shrink-resisting and anti-wrinkle treatment process for pure cotton fabrics. According to the process, a resin treatment process is added in a pretreatment process in the dyeing and finishing processes of the pure cotton fabrics, and an optimized preshrinking process and an optimized mercerizing process are adopted in a post-finishing process in the dyeing and finishing processes of the pure cotton fabrics, wherein due to the resin treatment process in pretreatment, officially resin and a cotton fiber form a three-dimensional net structure, thereby improving the dimension stability of cotton fabrics, and reducing the shrinkage rate of fabrics; and due to the preshrinking process, an overfeeding process is optimized, and because a multistage progressive overfeeding rate is adopted, a situation that the water shrinkage rate is increased because fine gauzes of fabrics are re-stretched due to stress is effectively prevented; a low alkali removal temperature is adopted in the mercerizing process, and therefore, the alkali removal effect is obvious, and the shaping effect on fabrics is strengthened. Compared with common processes, the process disclosed by the invention has the advantages of strong shrink-resisting and anti-wrinkle capabilities, soft handfeel of treated fabrics, and slight forced damage, and is strong in practicability.

Description

technical field [0001] The invention relates to a fabric processing technology, in particular to an anti-shrinkage and anti-wrinkle treatment technology for pure cotton fabrics. Background technique [0002] Pure cotton fabric is a textile made of cotton as raw material, which is interwoven vertically and horizontally by warp and weft yarns through a loom. Comfortable, sweat-absorbing, moisture-retaining, etc., are widely loved by consumers, but also because the pure cotton fabric itself needs to be stretched by a certain external force during the textile processing process, and after finishing, this stretch Stretching is in a temporary stable state. When soaking in water for washing, the water will gradually weaken the connection between the fiber molecules, and the friction on the fiber surface will decrease, thus destroying the temporary stable state, and the fiber will return to the state before the external force stretching, thus Cause consumer to often appear shrinkin...

When soaking in water for washing, the water will gradually weaken the connection between the fiber molecules, and the friction on the fiber surface will decrease, thus destroying the temporary stable state, and the fiber will return to the state before the external force stretching, thus Cause consumer to often appear shrinkage phenomenon when washing the pure cotton fabric that buys back, thereby caused certain trouble to consumer, thereby has limited the popularization and application of pure cotton fabric
