Embodiment 1

[0018] Embodiment 1. A nylon flame-retardant and infrared-resistant camouflage webbing production process, comprising the following steps:

[0019] S1, spinning, spinning nylon yarns with a Y-shaped monofilament cross section, specifically including: configuring spinning raw materials, preparing a spinning melt, and extruding the spinning melt through a spinneret hole on a spinneret to form a melt The body trickle and the melt trickle are cooled and solidified to form primary fibers, and the primary fibers are stretched and formed;

[0020] Specifically, the addition amount of cooling masterbatch in the spinning raw material was 2.2%, the temperature during spinning melt spinning was set to 260°C, and the stretching ratio of the spun fiber during drawing and forming was set to 4 times. Increase the spinning temperature of the spinning melt, increase the content of the cooling masterbatch, and increase the stretching ratio to increase the softness of the monofilament, so that t...

Embodiment 2

[0032] Embodiment 2, a nylon flame-retardant and infrared-resistant camouflage webbing production process, comprising the following steps:

[0033] S1, spinning, spinning nylon yarns with a Y-shaped monofilament cross section, specifically including: configuring spinning raw materials, preparing a spinning melt, and extruding the spinning melt through a spinneret hole on a spinneret to form a melt The body trickle and the melt trickle are cooled and solidified to form primary fibers, and the primary fibers are stretched and formed;

[0034] Specifically, the addition amount of cooling masterbatch in the spinning raw material was 2.2%, the temperature during spinning melt spinning was set to 260°C, and the stretching ratio of the spun fiber during drawing and forming was set to 4 times. Increase the spinning temperature of the spinning melt, increase the content of the cooling masterbatch, and increase the stretching ratio to increase the softness of the monofilament, so that t...

Embodiment 3

[0046] Embodiment 3, a kind of nylon flame retardant anti-infrared camouflage webbing production process, comprising the following steps:

[0047] S1, spinning, spinning nylon yarns with a Y-shaped monofilament cross section, specifically including: configuring spinning raw materials, preparing a spinning melt, and extruding the spinning melt through a spinneret hole on a spinneret to form a melt The body trickle and the melt trickle are cooled and solidified to form primary fibers, and the primary fibers are stretched and formed;

[0048]Specifically, the addition amount of cooling masterbatch in the spinning raw material was 2.2%, the temperature during spinning melt spinning was set to 260°C, and the stretching ratio of the spun fiber during drawing and forming was set to 4 times. Increase the spinning temperature of the spinning melt, increase the content of the cooling masterbatch, and increase the stretching ratio to increase the softness of the monofilament, so that the...

Abstract

The invention discloses a nylon flame-retardant infrared-resistant camouflage braid production process which comprises the following steps: spinning, braid weaving, braid washing, ground color dyeing, printing, high-temperature color development, post-treatment and flame-retardant treatment. The invention has the beneficial effects that: 1, the cross section of the monofilament ejected from the spinneret orifice is Y-shaped by transforming the spinneret orifice, so that the surface brightness of the monofilament is increased, and the reflective refraction of the surface of a nylon braid woven by nylon yarns consisting of the monofilament is improved, and the color and luster of the nylon braid are saturated; 2, the spinning temperature of a spinning melt is increased, the content of cooling master batches is increased, the stretching ratio is increased, the softness of monofilaments is improved, the monofilaments can be tightly cohered together without being dispersed after being fully stretched, and therefore the nylon yarn is not prone to fuzzing; and 3, the air pressure during padding is improved, and the stability of the pressure is ensured, so that the nylon braid is fully padded, the moisture content of the nylon braid during secondary dip dyeing is consistent, and the dyeing uniformity of the nylon braid is improved.

Description

technical field [0001] The invention relates to the technical field of camouflage webbing production, in particular to a production process of nylon flame-retardant and infrared-resistant camouflage webbing. Background technique [0002] Webbing is made of narrow fabrics or tubular fabrics from various yarns. There are many varieties of belt fabrics, which are widely used in various industrial sectors such as clothing, shoe materials, luggage, industry, agriculture, military supplies, and transportation. In the 1930s, webbing was produced by hand workshops, and the raw materials were cotton thread and hemp thread. In modern times, the raw materials for webbing have gradually developed to nylon, vinylon, polyester, polypropylene, spandex, viscose, etc., forming three types of technology: weaving, knitting, and knitting. The fabric structure includes plain, twill, satin, jacquard, double-layer, Multilayer, tubular and joint tissue. [0003] Nylon webbing has good elasticity...
