Problems solved by technology

However, in the actual production process, in addition to the difficulty of grasping the conditions of resin setting, it is also more difficult to grasp the enzyme washing, because the effect of enzyme washing also needs to grasp the balance between the effect of cloth surface and the loss of strength.

Embodiment

[0044] This embodiment provides a method for manufacturing a washable piece-dyed knitted fabric to produce a 50S / 1 double-sided (Interlock) fabric with a width of 58 inches and a weight of 190GM, CPI=90, WPI=55, such as figure 1 As shown in the process flow, it includes the following steps:

[0045] Knitting: Use 50S / 1 grey yarn to weave the stock according to 32G33”50C=129MM;

[0046] Scouring: With a bath ratio of 1:10, the use of 2g / L refining agent can stabilize ONE (Huntsman Chemical Trading Co., Ltd.), 2g / L NaOH with a mass concentration of 50%, and 3.6g / L specification of 27.5% H 2 O 2 The treatment agent of the solution is scoured under the conditions of a treatment temperature of 95°C and a treatment time of 45 minutes;

[0047] Enzyme washing: at a bath ratio of 1:10, using a washing solution containing 2.5g / L cellulose fiber enzyme (Cellusoft combi, Novozymes China Biotechnology Co., Ltd.) and adjusting the pH to 4.5-5.0 with NaAC and HAC. Enzyme washing is performed unde...

Abstract

The invention provides a manufacturing method of a washable piece-dyed knitted fabric. The production method comprises the following steps: knitting greige yarns into greige fabrics, sequentially scouring, enzyme washing, dyeing, opening, drying, liquid ammonia mercerizing, neutralizing, oversoftening, opening, drying, shaping, pre-shrinking, The described washable piece-dyed knitted fabric is obtained. The production method of the present invention adopts the steps of scouring, enzyme washing and dyeing, and then liquid ammonia mercerizing, which is beneficial to the effect of liquid ammonia mercerizing and the recycling of liquid ammonia, and combined with resin treatment, the dimensional stability of the knitted product obtained is better , the feel and color remain longer, and the cloth surface has high flatness, comfortable hand feeling, soft and elastic, and better strength. This production method not only improves the various performances of knitted products, but also increases its added value and technological content, and the use of recyclable liquid ammonia for treatment has the concept of green environmental protection.

Description

Technical field [0001] The invention relates to a method for manufacturing a washable piece-dyed knitted fabric, belonging to the technical field of knitted dyeing and finishing. Background technique [0002] Knitted fabrics are widely used in sportswear, casual clothes and underwear. They are comfortable, breathable and elastic. But its own dimensional stability is poor, and it is easy to deform, pilling and discoloration (whitening) after washing, which seriously affects the wearing performance. At present, the purpose of washing durability is generally achieved through the following methods: [0003] 1. Adopting a styling resin finishing method. The resin is cross-linked with cellulose fibers to improve the wrinkle resistance, elasticity and dimensional stability of the knitted fabric, and to a certain extent improve the anti-pilling and color change effect of the fabric after washing. However, it is difficult to grasp the temperature, time and dosage in the reaction condition...
