Description
Technical Field
The invention relates to the field of warp knitting machines, in particular to a tricot jacquard warp knitting machine with a jacquard.
Background
The jacquard fabric is a pattern formed by warp and weft tissue changes when the fabric is woven. Jacquard is usually realized by the yarn guide end deviation action of a jacquard guide needle, and the jacquard yarn transversely traverses is changed on the woven ground structure to form patterns. Jacquard needles are a unit in two courses, in one course only one offset can be done at the needle back. When the jacquard guide needle does not carry out jacquard, local weft insertion with two needle pitches is carried out to form a thin structure; when the jacquard guide needle is blocked, weft insertion with the needle pitch of 1 is carried out, and the jacquard yarns are wound on the longitudinal chaining after being contracted and wound to form meshes; when the jacquard guide needle pushes forward a stitch length to make 3-stitch weft insertion, a yarn is additionally padded between adjacent needles to form a thick structure.
Tricot machines are commonly used to weave warp knitted fabrics with simpler structure, such as fabrics, mosquito nets, headscarfs, bed sheets, small pattern household fabrics, and the like. Typically tricot machine fabrics are relatively loose, but have a relatively high fabric density. The tricot machine for tricot is high in production efficiency, one guide bar is 2-4, the other guide bar is 6-10, and the highest guide bar can reach 18. The machine degree is generally 700-1000 rpm, and the highest machine degree is 4400 rpm.
The tricot machine has the characteristic of high speed, but more guide bars cannot be used, so that the jacquard effect is single and simple, and is not flexible enough, and the variable and diversified jacquard effects are difficult to form; in addition, the force of the special knitting needle is large due to the special drawing structure, and the transverse movement of the yarn guide needle cannot be too large; these greatly limited applications of tricot machines, there are currently no tricot machines with jacquard on the market for weaving jacquard fabrics. The raschel warp knitting machine has a low fabric density and a fabric formed by the raschel warp knitting machine is not thick enough although the needle is subjected to a small force.
At present, home decoration textiles such as sofa cloth, pillowslip, curtains and the like cannot be directly woven by single needle bed through weaving, and are formed by secondary combination, such as embroidery, flocking and other processes.

2. The invention effectively solves the problem of overlarge pressure of the yarn on the yarn guide needle caused by the upward yarn outlet direction of the tricot machine by utilizing the yarn feeding mode of the creel.
3. The invention can simply, conveniently and obviously improve the needle pitch change of the tricot machine, thereby improving the jacquard flexibility and more easily realizing the complex and diversified jacquard effect; and the whole needle pitch can be lengthened under the condition of not increasing the traversing distance of the back of the yarn guide needle.
4. The invention adopts the process of forming loops by two ground combs after jacquard combing, the loops are firmly sleeved with each other, and the fabric is firm. The density of the fabric matched with the tricot is high, so that the formed fabric is thick and solid.
5. According to the jacquard machine, the jacquard flexibility is improved by using the jacquard comb, the complex and diversified jacquard effect is easier to realize, and the soft and firm fabric with clear and thick patterns can be woven by using a machine matching process and is used for home-decoration textiles such as sofa cloth, throw pillows, curtains and the like.
