Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings.

[0017] As shown in Figure 2, ① use the large bright fiber grade polyester chip with an amount of 75% by weight as the first raw material A, enter the material continuous drying tower 1, and make the big bright fiber grade polyester with a moisture content < 35PPm Dry slices, enter the first screw extruder 3, and become spinnable polyester melt through melt extrusion. The melt extrusion process of the first screw extruder 3 is equipped with 3 to 5 heating zones. The heating of each zone The temperature is set between 275°C and 295°C (for example: 275°C, 285°C, 295°C), and then the polyester melt is transported to the spinning box 5 and further evenly distributed to the spinning box 5. Among the "rice" type polyester and nylon composite components, it is a component. In addition, in the actual production process, a pre-filter can be set between the first screw extruder ...

Abstract

The invention discloses a bi-component polyester-brocade ultrafine drawing yarn which has beautiful appearance, excellent performance, simple process and easy operation and its production method; among them the components of brocade includes polyamide 6 slicers in optical fiber grade which are distributed in '*'shape, the component of polyester includes polyester slicers in optical fiber grade which are distributed in other spaces; said production method is: drying, melting and squeezing said two raw materials, then transporting them into the '*'shape polyester-brocade composite assemblies in spinning box, squeezing out two components in composite assemblies at the same time, drying and shaping by lateral blowing, oiling by oiling system, then guiding them to the first and second heat roller through pre-network nozzle blowing network, last winding-up tows through winding head and preparing the desired bi-component polyester-brocade ultrafine drawing yarn, the rolling speed when winding-up is 3900-5300m/min. Said products can be used in the high-grade textiles productions of artificial chamois skin, peachskin suede, super-high density textiles and other textiles widely.

Description

technical field [0001] The invention relates to a two-component polyester nylon ultrafine drawn yarn and a production method thereof. Background technique [0002] Two-component polyester nylon microfiber monofilament is small in size, soft and fluffy, moisture-absorbing and breathable, soft in luster, and comfortable to wear. It is widely used in jeanette series products. After sanding, the style is delicate and plump. It has waterproof effect and is deeply loved by people. [0003] At present, two-component polyester nylon microfibers are usually processed in a two-step process, using ordinary fiber-grade polyester chips (PET) and ordinary fiber-grade polyamide 6 chips (also known as: nylon 6, PA6) as raw materials , respectively, after being dried, extruded and melted, distributed to the "rice" or orange petal-shaped polyester-nylon composite components in the spinning box, and then processed by the pre-orientation process and the texturing process respectively to obtain...
