Environment-friendly fibers are finding their way into more China-made textile bags as suppliers address growing overseas demand for sustainable products.

Factories are blending bamboo rayon into conventional cotton canvas models. A few are even switching to organic variants of the latter. Both options result in smoother fabrics.

Instead of bleaching and dyeing the materials, companies are offering off-white designs. Naturally beige and green cotton grown without pesticides are available as well. This strategy not only eliminates toxins but also reduces energy consumption and labor expenses.

For buyers looking for more vibrant colors, exporters are encouraging them to source their own pigment.

Other textiles are sent to third-party testing institutes to ensure that inputs are recyclable.

In terms of aesthetics, manufacturers are employing various trimmings that serve as a counterpoint to the textiles. For example, plaited straw adds dimension to printed silk, while leather gives a refined or preppy appearance. Embroidery, patches, rhinestones, tassels, zippers and rosettes are incorporated.

Textile bags from China are either cut and sewn, crocheted or knitted. The first is dominated by polyester and cotton releases, although nylon is also utilized. The density is either 190 or 210 tex. Products formed by looping yarns are mostly made of rayon and wool.

T/C, cotton and polyester are the usual lining choices. Many canvas pieces do not have an inner layer because of the strength of the weave. A plastic board can be inserted at the bottom for better reinforcement.

Silk-screening, and heat-transfer and offset printing are the mainstream methods for applying patterns and logos. Zippers, snap buttons, hook-and-loop tabs and drawstrings are the common closures.

Prices vary from just below $2.50 to $15 per piece based on materials and construction complexity. This is about 10 percent higher than three months earlier. Quotes are anticipated to rise up to 15 percent in the next half-year.

Low-end models are made of locally sourced textiles. They may or may not have lining and an interior pocket. The fastener is a nylon zipper.

Upscale designs come in heavier fabric and are densely embellished. More compartments and outer sections are incorporated.

In the 12 months to May 2011, China exported nearly $1.5 billion plastic and textile bags, increasing 33 percent YoY. The US is the main export market, accounting for one-fourth of revenue. Guangdong is the largest hub, contributing at least 30 percent to the national total.
