Embodiment 1

[0070] A kind of polylactic acid fiber blended fabric of the present invention and production method adopt the polylactic acid fiber of following weight percentage composition, bamboo fiber, Newdale blended textile to form:

[0071] Polylactic acid fiber 44

[0072] bamboo fiber 50

[0073] Newdale 6

[0074] The production method includes four major production process steps of spinning - weaving - printing and dyeing - post-finishing, among which

[0075] C. Spinning

[0076] Including the following processes: blowing - carding - drawing - roving - spinning - winding

[0077] ①, cleaning process

[0078] Polylactic acid fiber, bamboo fiber, and Newdale are cleaned separately and rolled into rolls

[0079] a. Polylactic acid fiber: Blowing adopts the method of "grasping frequently, catching less, beating more loosely and lightly", increasing the pressure of cotton laps, and doing a good job of pretreatment. The process conditions of blowing:

[0080] Lap weight g / m 420 ...

Embodiment 2- Embodiment 3

[0132] According to the method and steps of Example 1, the polylactic acid fiber, bamboo fiber and Newdale blended fabric formed according to the weight percentage of Table 1 are made: 53 / 40 / 7, 60 / 30 / 10, the product obtained through testing Technical index is basically the same as embodiment 1.

Abstract

The invention relates to a polylactic acid fiber blended fabric and a production method. The polylactic acid fiber blended fabric is woven by blending the following components in percentage by weight: 35-65% of polylactic acid fiber, 60-30% of bamboo fiber and 5-10% of Newdal. The production method comprises the processing steps of spinning, weaving, printing and dyeing and later finishing. Through the invention, the natural ecological functions and excellent performance of the polylactic acid fiber, bamboo fiber and Newdal are maintained, and the elasticity and shape maintenance are good. The glass transition temperature of the polylactic acid fiber is improved so that the weaving is easier. Meanwhile, the strength and the pilling resistance of the fabric are enhanced, and the shape maintenance of the fabric is further improved.

Description

technical field [0001] The invention relates to a polylactic acid fiber blended fabric and a production method. Background technique [0002] Polylactic acid fiber, commonly known as corn fiber, is biodegradable, has good moisture absorption and perspiration breathability, good wrinkle resistance and resilience, high tensile strength, silk luster, soft and smooth hand feeling, and comfortable to wear. It is flame retardant, easy to color, and also has antibacterial and deodorizing functions. It is a natural cycle process from raw material, production, use to disposal. It is an ecological fiber that is non-polluting and non-toxic to the environment. Polylactic acid has a very high development value. However, the melting point of polylactic acid fiber is low, the glass transition temperature is low, it is sensitive to heat, it is easy to be stretched under force, and the weaving process is demanding. [0003] Bamboo fiber is a regenerated cellulose fiber made from bamboo thr...
