Principle of Non-woven bag

- Apr 05, 2018 -

The non-woven fabric is a non-woven fabric, and it directly utilizes a high-polymer section, short fiber, or filament yarn through a variety of web forming methods and consolidation techniques to form a novel fiber product having a soft, breathable, and planar structure. The advantages of non-woven bags compared to traditional plastic bags: Non-woven bags are inexpensive, environmentally friendly, practical, widely used, and have prominent advertising positions. Applicable to all types of business activities and exhibition fairs, is an ideal promotional gifts for enterprises and institutions.

The raw material of the non-woven bag is polypropylene, and the raw material of the plastic bag is polyethylene. Although the two materials have similar names, their chemical structures are quite different. The chemical molecular structure of polyethylene is very stable and extremely difficult to degrade. Therefore, the plastic bag needs 300 years to be decomposed; while the chemical structure of polypropylene is not strong, the molecular chain can be easily broken and can be effectively degraded. , And in the non-toxic form into the next environmental cycle, a non-woven bag can be completely decomposed within 90 days.

Non-woven fabrics are products that do not require a textile process and are made of fabrics, also called non-woven fabrics. Because it is only the orientation of the textile staple fibers or filaments or random support, forming a network structure, and then using mechanical, thermal adhesive or chemical methods can be made of reinforcement. Most non-woven bags are spunbonded non-woven fabrics.

Simply put: the non-woven fabrics are not interwoven or knitted together by a single yarn, but the fibers are directly bonded together by physical methods, so when you get the sticky name in your clothes At that time, you will find that it is impossible to pull out the thread. Non-woven fabrics have broken through the traditional textile principles, and have the characteristics of short process flow, high production speed, high output, low cost, wide use, and many raw material sources.

Laminated non-woven bag, the product adopts casting method, it is compound and firm, it is not sticky in the compounding process, it has soft hand feeling, no plastic feeling, no skin irritation, it is suitable for single-use disposable medical sheets, sheets, and surgical gowns. Separation suits, protective clothing, shoe covers, and other health protection products; this kind of cloth bag called non-woven bags.
