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] The present embodiment provides a kind of manufacture method of washable piece-dyed knitted fabric, to produce the 50S / 1 double-sided (Interlock) fabric of finished product width 58inch, finished product grammage 190GM, CPI=90, WPI=55, such as figure 1 As shown in the technological process, it comprises the following steps:

[0045] Knitting: use 50S / 1 gray yarn to weave blank according to 32G33”50C=129MM;

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

[0047] Enzyme washing: with a bath ratio of 1:10, use a washing solution containing 2.5 g / L cellulose cellulase (Cellusoft combi, Novozymes China Biotechnology Co., Ltd.) and adjust the pH value to 4.5-5.0 with ...

Abstract

The invention provides a production method of washable piece-dyed knitted fabric. The production method comprises steps as follows: undyed yarn is knitted into gray fabric, the gray fabric is sequentially subjected to boiling-off, enzyme wash, dyeing, scotching, drying, liquid ammonia mercerization, neutralization, softening, scotching, drying, setting and preshinking, and the washable piece-dyed knitted fabric is obtained. The production method adopts steps of boiling-off, enzyme wash, dyeing and liquid ammonia mercerization sequentially, the liquid ammonia mercerization effect and the liquid ammonia recycling are facilitated, and resin treatment is combined, so that an obtained knitted product has better dimensional stability, and more durable hand feeling and color are kept; and the fabric has high flatness, touches comfortable and is soft, elastic and better in strength. By means of the production method, various properties of the knitted product are improved, the additional value and the technological content of the knitted product are increased, and recyclable liquid ammonia used for treatment is environment-friendly.

Description

technical field [0001] The invention relates to a manufacturing method of a washable piece-dyed knitted fabric, which belongs to the technical field of knitting dyeing and finishing. Background technique [0002] Knitted fabrics are widely used in sportswear, casual clothes and underwear, and are characterized by comfort, breathability and good elasticity. However, its poor dimensional stability, easy deformation, pilling and discoloration (whitening) after washing seriously affect the wearing performance. At present, the purpose of washing resistance is generally achieved through the following methods: [0003] 1. Using the finishing method of shaping resin, the resin improves the wrinkle resistance, elasticity and dimensional stability of the knitted fabric by cross-linking with the cellulose fiber, and to a certain extent improves the anti-pilling and color change effect of the fabric after washing. However, the temperature, time and dosage in the reaction conditions of...
