Problems solved by technology

There are two kinds of yarns with different properties in the carding process, the carding effect is not good, and the mixing ratio of the two fibers cannot be controlled.
And there is no report for the research of PTT and spun silk adopting strip mixing

Embodiment 1

[0036] The production process of a spun silk / PTT blended yarn involved in this embodiment comprises the following steps: step S1 pretreatment of spun silk, step S2 preparation of spun silk pre-drawing, step S3 preparation of PTT fiber pre-drawing, step S4 preparation of mixed cooked sliver, step S5 preparation of blended yarn, step S6 dyeing of blended yarn, step S7 winding.

[0037] In step S1 pretreatment of spun silk, the pretreatment of spun silk includes pretreatment and retreatment. The selected spun silk fiber has a linear density above 1.11dtex and a length of 70-120mm.

[0038]The pretreatment is to immerse the spun silk fiber in the pretreatment solution at room temperature according to the bath ratio of 1:10, and under the condition of 25kHz ultrasonic wave, the temperature is raised to 70°C at a speed of 0.7°C / min, and the temperature is kept for 30min; After the pretreatment liquid is discharged, wash it with water at 50°C, add a dispersing chelating agent YSN2g / ...

Embodiment 2

[0064] The production process of a spun silk / PTT blended yarn involved in this embodiment comprises the following steps: step S1 pretreatment of spun silk, step S2 preparation of spun silk pre-drawing, step S3 preparation of PTT fiber pre-drawing, step S4 preparation of mixed cooked sliver, step S5 preparation of blended yarn, step S6 dyeing of blended yarn, step S7, cylinder.

[0065] In step S1 pretreatment of spun silk, the pretreatment of spun silk includes pretreatment and retreatment. The selected spun silk fiber has a linear density above 1.11dtex and a length of 120mm.

[0066] The pretreatment is to immerse the spun silk fiber in the pretreatment solution at room temperature according to the bath ratio of 1:20, and under the condition of 59kHz ultrasonic wave, the temperature is raised to 75°C at a speed of 1°C / min, and the temperature is kept for 40min; After the pretreatment liquid is discharged, wash it with clear water at 55°C, add a dispersing chelating agent YS...

Abstract

The invention discloses a production process of spun silk/PTT blended yarn. The process comprises the following steps of S1, pretreatment of the spun silk; S2, preparation for pre-drawing of the spunsilk; S3, preparation for pre-drawing of PTT fibers; S4, preparation of mixed drawn slivers; S5, preparation of the blended yarn; S6, dyeing of the blended yarn; S7, winding. According to the production process of the spun silk/PTT blended yarn, the spun silk and the PTT yarn are separately subjected to carding and sliver mixing during blending so that the carding process can be controlled more easily, and the blending proportion of the two fibers in the prepared blended yarn can be precisely controlled; the blended yarn has better properties and higher yarn evenness, and the quality of the blended yarn is improved.

Description

technical field [0001] The invention relates to the technical field of novel textile yarns, in particular to a production process of spun silk / PTT blended yarns. Background technique [0002] Silk fabric has pearl-like soft luster, soft and smooth to the touch, especially the skin-fitting feeling is incomparable to other fibers. It has good hygroscopicity, good air permeability, good drape and elegant feeling when worn in summer. However, silk fabrics also have certain defects, such as: easy to wrinkle, poor elasticity, easy to shrink, yellowing, etc. In addition, real silk products have a single material, with a single mulberry silk as the main raw material, which has a narrow range of use and short wearing seasons. [0003] Polytrimethylene terephthalate (PTT) fiber has excellent resilience performance, and at the same time has the softness of nylon, the bulkiness of acrylic fiber, and the stain resistance of polyester, so it has a wide range of applications in clothing f...
