Abstract

The invention discloses a dense straight type cleaning terry fabric and a weaving method thereof and a special auxiliary needle hook, wherein a plurality of auxiliary needle hooks penetrate through a reed and are connected in series through a pair of square pin latch seats on a temple seat, and during weaving, auxiliary weft yarns are driven into upper layer sheds formed by two groups of terry warp yarns respectively in sequence, so that the auxiliary needle hooks hook the auxiliary weft yarns, the auxiliary weft yarns hook the terry warp yarns positioned on the upper layer in the upper layer shed, the parts of the terry warp yarns which are not hooked by the auxiliary needle are interwoven with the ground warp yarns and the base fabric weft yarns of a base fabric, the parts of the terry warp yarns which are not hooked by the auxiliary weft yarns form terry yarns, the parts which are not hooked are woven into the base fabric, after weaving, the fixed ends of the auxiliary weft yarns positioned on one side of the fabric are released, and the auxiliary weft yarns are simultaneously pulled out of the fabric.

Description

Dense straight type cleaning terry fabric and weaving method thereof and special auxiliary needle hook Technical Field The invention relates to the technical field of textile of cleaning fabrics with a terry structure, in particular to a dense straight cleaning terry fabric, a weaving method thereof and a special auxiliary needle hook. Background The terry fabric is widely applied to products such as bath towels, cleaning cloths, scouring pads and the like due to a fluffy and water-absorbing terry structure formed on the surface of the terry fabric. For functional cleaning fabrics, especially scrubbing products with strong scratch, soil release and durability properties, not only are loops required to have high density, but also loops are required to be uniform in height and upright to ensure uniform, strong and durable cleaning. Currently, the main technical means for forming such straight loops in the industry mainly include: 1. In the process of weaving, a metal or plastic height-fixing sheet with a specific height is inserted into the warp yarn layer, and the looped warp yarn surrounds the height-fixing sheet to form a looped pile. The method can directly control the height of the terry, but has the problems of high consumption of fixed height pieces, complicated management, easy aggravation of reed abrasion, possibility of yarn damage and the like, has poor adaptability in high-speed weaving and has lower production efficiency. 2. Mechanical action by making the difference in relative displacement between warp and weft yarns to form loops by complex mechanical mechanisms such as moving the fell (cloth movement) or varying the beat-up stroke (long and short beat-up). The method has extremely high requirements on the mechanical structure of the loom, high equipment manufacturing cost, complex process adjustment and maintenance and great difficulty in controlling the stability and consistency of the pile height. 3. The water-soluble weft yarn method is to introduce water-soluble chemical fiber (such as PVA) as temporary supporting weft yarn during weaving, and to immerse the fabric in hot water to dissolve the weft yarn after weaving, thereby releasing the terry. The method can form good terry, but involves the environmental protection problems of water consumption, energy consumption, wastewater treatment and the like, And the raw material cost and the post-treatment process are increased, and the production flow is long. In summary, the prior art generally faces challenges such as complex equipment, high cost, limited production efficiency or insufficient environmental friendliness. Therefore, a technical scheme which is novel in principle, simple in equipment, efficient, environment-friendly and capable of stably producing high-quality straight terry fabrics is needed in the industry. Disclosure of Invention The invention aims to provide a dense straight type terry cloth for cleaning, a weaving method thereof and a special auxiliary needle hook, and aims to overcome the defects in the prior art. The invention aims to completely abandon the dependence on a physical fixed-height sheet, a complex cloth-motion/long-short beating-up mechanism and chemical water-soluble yarns, and provides a subversion solution which has the advantages of low equipment transformation cost, simple process principle, stable operation, environmental friendliness and capability of efficiently producing dense, straight and highly uniform looped fabrics. The technical aim of the invention is realized by the following technical scheme: the present invention provides in a first aspect a dedicated auxiliary hook for weaving dense straight terry fabrics, the auxiliary hook being an elongated sheet member independent of the loom reed, comprising: the front end of the auxiliary needle hook is a front part which can be inserted between reed teeth; The rear end of the auxiliary needle hook is provided with a connecting part for connecting a plurality of auxiliary needle hooks at a uniform height and a uniform front and rear position and a guiding part for guiding weft yarns, and the connecting part at the rear end of the auxiliary needle hook is also provided with a waist-shaped long hole, and the auxiliary needle hooks are connected in series through a pin of a pin seat arranged on a side support seat of the loom; And a hooking part between the guiding part and the front part is a hook structure with an opening facing the weaving port direction, and the hook structure is used for hooking the inserted weft yarn during beating-up. By adopting the technical scheme, a plurality of auxiliary hooks are arranged and fixedly installed at equal intervals (for example, every interval of 2mm, 5mm, 10 mm, 20 mm or 50 mm) or according to a specific non-uniform pattern along the length direction of the reed of the shuttle machine according to the transverse distribution density of the required loops, the front part of the auxiliary hooks positioned at
