Good afternoon, friends! Haven’t seen you in a week, are you looking forward to CTMTC news? This week we will introduce filament to you. In the vast world of materials, filament occupies a unique and important position, integrating various characteristics and wide applications into every aspect of our lives.
From the perspective of raw materials, the sources of filament are diverse and abundant. Chemical fiber filaments are made from various polymers, with polyester filaments derived from the polymerization reaction of terephthalic acid and ethylene glycol, which have a wide range of raw material sources and relatively controllable costs, laying the foundation for large-scale production; Nylon filament is made from polyamide as raw material and is synthesized through complex chemical processes, possessing unique performance advantages. The silk in natural filaments comes from the diligent spinning and cocooning of silkworms. Its natural, environmentally friendly, and protein rich characteristics endow it with innate skin friendly and noble attributes.
In terms of production technology, the production of chemical fiber filaments is like a precise technological dance. The melt spinning method heats and melts the polymer, then extrudes a fine stream through a spinneret and rapidly solidifies into silk in cooling air; The solution spinning method involves dissolving the polymer into a solution and spinning it, followed by processes such as stretching, curling, and heat setting to precisely control the crystallinity, orientation, and morphological structure of the filament, thereby creating filament products with different performance characteristics. The acquisition of silk requires traditional processes such as raising silkworms, cocooning, selecting cocoons, boiling cocoons, and spinning silk. Each step contains the craftsmanship and wisdom passed down by our ancestors, in order to extract continuous, smooth, and fine filaments from silkworm cocoons.
Specification characterization is a key means of finely distinguishing long filaments. Denier (D) is a commonly used indicator, which measures the thickness of 9000 meters of filament by measuring its weight in grams at a predetermined moisture regain. The higher the value, the thicker the filament. For example, 30D filament is slender and lightweight, suitable for weaving lightweight summer clothing fabrics; The 150D filament is relatively thick and is commonly used to make thick winter clothing or industrial textiles. Equally important is dtex, which provides precise quantitative basis for the standardized production and application of long fibers by measuring the weight grams of 10000 meters of fibers at a predetermined moisture regain.
The performance is also the highlight of the charm of long filaments. Polyester filament has excellent performance in outdoor equipment, industrial filtration and other fields due to its high strength and good dimensional stability. It can withstand large external forces and is not easily deformed; The wear resistance of nylon filament is unique, and it frequently appears in products such as sportswear and hiking ropes, ensuring the durability of the product in frequent friction scenarios; Silk filament, with its soft and smooth hand feel, good moisture absorption and glossiness, has become the preferred material for high-end home textiles and close fitting clothing, bringing people a dual experience of comfort and luxury.
The application fields of filament manufactured by CTMTC are beyond imagination. In the fashion textile industry, from elegant silk cheongsams to modern functional sportswear, from exquisite bedding four piece sets to blackout and heat-insulating curtain fabrics, long filaments shape a rich and colorful textile world with their unique texture and performance; In industrial production, long filaments transform into tough tire cords, enhancing the structural strength of tires and ensuring driving safety; It is also used as a key material in various fields such as filtration, geotechnical engineering, and medical care. It accurately intercepts fine particles in filter cloth, reinforces soil and prevents erosion in geotextiles, and assists in wound healing in surgical sutures. It silently contributes an indispensable force to the efficient operation of modern society and the improvement of human quality of life.
