Development of non-woven bags in the field of environmental protection bags:

Fuzhou its origin is introduced into non-woven polypropylene, is the first ingredient is a kind of don't need a spinning weaving, fabric, textile short fibers may be only the filament for directional or random supporting columns, a fiber network structure, and then choose the way such as mechanical, hot glue or chemical reinforcement. Simple say is: it is not by one of the interlaced yarn and knitting together, but the fiber directly by the steric (physical) method together, so, when did you get your clothes stick said, you will find, is can't afford the loose thread ends. Nonwoven fabric breaks through the traditional textile principle, and has the characteristics of short technological process, fast production speed, high output value, low cost, wide use, and abundant quality materials. As a product that existed as early as 10 years ago, nonwoven fabric is not widely used at the time, and its development is still in recent years. The primary reason for this is to benefit from the environmental protection products we propose now, as well as their unique characteristics:

1. Excellent softness

2. Non-toxic and antibacterial

3. Excellent ventilation and waterproof function

4. High tensile strength and elongation

5. Excellent processing function and thermal stability

6. Corrosion resistance

7. Recyclable retention

Because its price is relatively low, it is now widely used in industries such as industry, agriculture and health care.

Non-woven environmental protection bag is a kind of environmental protection product. It is now widely used in shopping, mainly used in packaging, advertising, electronics, clothing, decoration and other products. Because of its printability and beautiful and generous. Elegant, and therefore very fashionable women, became their shopping shopping bag of choice, even now many children are carrying non-woven bags to school. So now in Hong Kong, Canada, Europe and many other local supermarkets, they have replaced ordinary PP, PE and other plastic bags with non-woven cloth bags.

With the increasing awareness of environmental protection and the deepening of people's understanding of non-woven fabrics, I believe that in the future market, non-woven products will be more and more useful, and the market will be bigger and bigger.

Testing the quality of non-woven environmental bags? That's it.

1. Sensory inspection

(1) color: visually measure the color of the non-woven bag in natural light.

(2) odor: smell the non-woven bag.

2. Check the appearance quality of non-woven bag

Visual measurement in natural light, using visual hand - feel method for inspection.

3. Material requirements inspection

Check the certificate of eligibility for non-woven bags.

4. Scale deviation inspection

The non-woven bag was measured with a measuring tool of 1mm.

5. Non-woven bag sewing needs to be checked

(1) sewing appearance: lay the non-woven bag flat on the inspection table and measure it with a ruler and inspect it visually.

(2) stitch density: count the stitch number after measuring the length of every 3cm part with a ruler.

(3) non-woven bag suture strength: according to GB/T 3923.1-1997 rules. The sample length is 300mm and the width is 50mm. The stitched sample should be kept at both ends of the stitching place for 4 stitches and knotted at the end to avoid loose stitching.

6. Physical and mechanical performance inspection

(1) cracking strength: according to GB/T 3923.1-1997 rules. Samples were taken on the non-woven bag, and the sample was 300mm long and 50mm wide.

(2) non-woven bag lifting experiment: the bag lifting fatigue experiment machine used by the experimental machine has an amplitude of 30mm plus or minus 2mm and a frequency of 2Hz~3Hz.
