Royal Group Geotextile Production

1. Knitted geotextiles Knitted geotextiles by a string of one or more yarns circle from each other, rarely used geotextile. But with directional fabric structure geotextile advent, people gradually changed his views. DSF fabric comprises uniaxial fabric, biaxial fabric and multi-axial fabrics.

2. Nonwoven geotextiles nonwoven geotextiles are mainly spunbonded, needle-punched,hot-melt and adhesive type geotextile, it has lower strength and initial modulus,but good elongation at break. Nonwoven geotextile has good elasticity, good frictional properties, porosity and uniform, high filtration efficiency. Non-woven geotextile features simple production process, high labor efficiency, low cost, multi-process changes.

3.Woven geotextile woven geotextile is composed of two groups of filaments or flat woven into the fabric wear, a variety of single-layer woven geotextile (also known as anti-geotextile cloth), double layer geotextile (also known as geotextile mold cloth bags) and woven fabric impermeable.

PET, PP and Biomass are used for cleanliness of environment.

pet flakes

Recycled Polyester staple fibre is a synthetic man made fibre made from Polyester waste and post consumed PET bottles. It is used in Non-Woven carpets, wadding, filtration industries, as a polyfill for stuffing cushions, pillows, soft toys, quilts. Its also used for spinning yarns and making geotextiles. Hollow Polyester staple fiber gives good resilience properties and is used to make premium pillows, cushions and quilts. We can manufacture solid and hollow Recycled Polyester Fibre in various deniers and cut-lengths.

Jute in Bangladesh

Jute is the second most important vegetable fiber after cotton due to its versatility. Jute is used chiefly to make cloth for wrapping bales of raw cotton, and to make sacks and coarse cloth. The fibers are also woven into curtains, chair coverings, carpets, area rugs, hessian cloth, and backing for linoleum. While jute is being replaced by synthetic materials in many of these uses, some uses take advantage of jute’s biodegradable nature, where synthetics would be unsuitable.

Manufacturing Recycled Polyester Staple Fibre

Worldwide millions of PET bottle are consumed daily and thrown to trash. PET is also called polyester. Polyester is a synthetic polymer made of purified terephthalic acid (PTA) or its dimethyl ester dimethyl terephthalate (DMT) and monoethylene glycol (MEG). Since PET bottles are practically non bio-degradable, its was very difficult to dispose them. New technology was developed in Europe, Korea and finally China which helped in recycling these post consumed PET bottles to make man made fibres like Recycled Polyester Staple Fiber.

geotextile fibre

These fibers are then used to make non woven carpet for auto-mobiles, making quilts, yarns, pillows etc. First bottles arrived in a factory, collected from trash, in bale form. These bales are opened and manually sorted to take out contaminations like iron, PVC, stones etc.

pet

Once cleared these PET bottles are crushed to make 12-15 mm flakes and are hot washed in chemical solution containing 2% solution of Sodium Hydroxide. This chemicals helps in taking out glue from bottles and also cleaning them. The overall contaminations in PET flakes should not be more then 200 ppm. These flakes are then dried and taken to vacuum driers where surface moisture as well as inherent moisture is taken out and flakes becomes soft/crystallized and dried. Moisture held within the PET flakes itself is known as inherent moisture. The Driers helps to reduce the inherent moisture to less then 200 PPM. These dried flakes are then taken to Extruder for spinning. Spinneret are available to make either hollow or solid PSF of varying denier (1.5Den 50Den).

filament

Filaments coming out of spinning are collected in cans or bobbins. This completes the spinning. Hollow and Solid PSF can be treated to make Siliconized, conjugated, polyfill, harsh, bouncy, anti static, anti fungal. In second step these cans are taken to Creel area where many cans or bobbins are combined to make tow and stretched several times in a chemical hot bath to make fibre. These fibres are then dried and relaxed in a relaxer and cut in various cut length before bale packing.
