Embodiment 1

[0012] A preparation method of low-shrinkage composite yarn, the inner core of the yarn is made of spandex yarn, characterized in that the outer skin of the yarn is made of glass fiber, crosslinking agent, antioxidant, flame retardant, antistatic agent, orange The leather is melt-coated and dried. The drying method is: vacuum drying at a temperature of 42 degrees Celsius for 5 minutes, and then vacuum drying at room temperature for 30 minutes.

[0013] The sheath of the yarn was melt coated and dried by 7 parts glass fiber, 2 parts crosslinking agent, 0.5 part antioxidant, 1 part antistatic agent and 2 parts orange peel. The melting temperature is 150 degrees Celsius. The diameter of the glass fiber is 5-10um. The inner core of the yarn is twisted with 2 spandex filaments. Described antioxidant is DLTP.

Embodiment 2

[0015] A preparation method of low-shrinkage composite yarn, the inner core of the yarn is made of spandex yarn, characterized in that the outer skin of the yarn is made of glass fiber, crosslinking agent, antioxidant, flame retardant, antistatic agent, orange The leather is melt-coated and dried, and the drying method is: vacuum drying at room temperature for 50 minutes.

[0016] The sheath of the yarn was melt coated and dried by 7 parts glass fiber, 2 parts crosslinking agent, 0.5 part antioxidant, 1 part antistatic agent and 2 parts orange peel. The melting temperature is 150 degrees Celsius. The diameter of the glass fiber is 5-10um. The inner core of the yarn is twisted with 2 spandex filaments. Described antioxidant is DLTP.

[0017] The shrinkage rate of the material of embodiment 1 and 2 is measured, the shrinkage rate of embodiment 1 is 2% in the drying process (that is, the shrinkage volume accounts for the total volume percentage before drying), and the shrinkag...

Abstract

The invention belongs to the field of composite yarns and concretely relates to a low-contraction composite yarn preparation method. The inner core of the yarn is formed by spandex filaments. The low-contraction composite yarn preparation method is characterized in that glass fibers, cross-linking agent, anti-oxidant, fire retardant, antistatic agent and orange peel are fused, then plastered and dried to form the external skin of the yarn. The dying method is that the above components are dried for two to five minutes at vacuum environment at the temperature of 42 DEG C and then dried for 30 to 60 minutes at vacuum environment at the normal temperature; the glass fibers are linked to form a net structure by the cross-linking agent to further enhance strength of the composite yarn. With the dying method, contraction of the composite yarn during natural drying can be prevented; and yarn tension force can be guaranteed at the vacuum environment, so contraction of the yarns can be avoided.

Description

technical field [0001] The invention belongs to the field of composite yarns, and in particular relates to a preparation method of low-shrinkage composite yarns. Background technique [0002] At present, the existing composite yarns are limited in material composition, and the antistatic effect is not strong, and they also have a certain shrinkage rate. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned problems, and provide a kind of preparation method of composite yarn with low shrinkage rate. [0004] In order to achieve the above object, the technical solution adopted in the present invention is: a preparation method of low-shrinkage composite yarn, the inner core of the yarn is made of spandex yarn, and it is characterized in that the outer skin of the yarn is made of glass fiber, cross-linked agent, antioxidant, flame retardant, antistatic agent, and orange peel, which are melt-coated and dried. The dryin...
