Problems solved by technology

When the conventional non-woven fabric is used as a rag, due to the small fibers in the non-woven fabric, the adsorption force is not strong when used as a rag, and the small limit cannot clean the surface and surface gaps of the wiped object well.
Therefore, it is a technical breakthrough to physically modify the non-woven fabric by the adsorption force and roughness of the fluffy loops after planting loops on the non-woven fabric, which cannot be achieved by any conventional equipment including quilting machines, quilting machines, and stretching machines. Parallel knitting at very small pitches

Embodiment 1

[0024] like figure 1 As shown, a non-woven fabric loop planting process is characterized in that it includes the following steps: plant loops 3 on the non-woven fabric 1 and reserve the loops. Puncture with a terry piercing needle with a terry thread, then bring the loop out and reserve it with a pin; then the terry piercing needle exits.

[0025] In this embodiment, the existing structure is used to make the pile fall down: the needle with the pile piercing needle is inserted into the non-woven fabric, and then the needle is inserted into the pile thread, and then the needle with the pile piercing exits and pulls the pile thread, and then the nonwoven When the cloth feeds or the needle moves backward, the loop thread falls backwards along the trend.

[0026] Secure the loops to the non-woven fabric with chain stitch 3. It specifically includes: using a puncture array poured with fixed thread needles to puncture the non-woven fabric with loops; using a crochet needle array p...

Embodiment 2

[0030] like figure 2 Shown: This embodiment is an improvement of Embodiment 1. In this embodiment, in order to increase the lateral stretch resistance of the product, it also includes that the loop puncture needle moves laterally by one needle position after the loop puncture needle penetrates into the non-woven fabric for the second piercing.

Embodiment 3

[0031] Embodiment 3: This embodiment is an improvement of Embodiment 1. A pressing roller is used to set between the loop piercing needle and the fixed thread piercing needle, and the pressing roller is used to overwhelm the pile to form an overturned pile.

[0032] like image 3 Shown: a non-woven fabric terry planting process equipment, including a terry puncture needle 4, and a needle 5 that cooperates with the terry puncture needle to realize terry reservation; it also includes a fixed line puncture needle array cast in one 6, and the crochet needle array which is located below the puncture needle array and cooperates with the puncture needle to realize the hook and loop, and complete the chain stitch. The fixed line needle spacing is 14 needles within 1 inch.

Abstract

The invention relates to the field of spinning, and discloses a non-woven fabric looped pile planting process. Looped piles are planted on non-woven fabric, the looped piles are reserved, the looped piles are fixed to the non-woven fabric through chain stitches; the invention also discloses non-woven fabric looped pile planting process equipment; the equipment comprises a looped pile puncture needle and an insertion needle matched with the looped pile puncture needle to achieve looped pile reservation; the equipment also comprises a fixed line puncture needle array which is poured into a whole, and a crochet hook array which is located below the puncture needle array and matched with the puncture needles to achieve loop hooking and loop sleeving and complete chain type stitches. The looped pile threads and the chain stitches for fixing are combined to attach looped piles to the non-woven fabric, ultra-high-density processing is achieved in a small area, the use characteristics of the non-woven fabric are greatly improved, covering threads can be replaced with threads with special functions according to requirements, and the use characteristics and use scenes of the non-woven fabric are increased.

Description

technical field [0001] The invention relates to the textile field, in particular to the loop planting process and equipment for non-woven fabrics. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics, are composed of oriented or random fibers. Its manufacturing process is to form a web structure formed by directional or random arrangement of short textile fibers or their filaments, and then strengthen them to a certain extent by means of mechanical, thermal bonding or chemical reinforcement. , Non-woven fabrics have the characteristics of short production process, fast production speed, high output, low cost, wide application and many sources of raw materials. Lightweight, soft, water-repellent, breathable, non-toxic, non-irritating, anti-bacterial, chemical-resistant, anti-bacterial, and good physical properties. When conventional non-woven fabrics are used as rags, due to the small fibers in the non-woven fabrics, the adsorption force is not s...
